Chapter 298 Past, Present, Future

"Ready to fight!"

   At the same time as the voice fell, the five people cooperated tacitly and spread out to the surrounding bunkers.

Lao Bai rushed into the building on the street, kicked open the half-closed door, put the cuboid box containing the fuel rods in a safe place, loaded the sickle assault rifle in his hand, and quickly approached by the window.

  The action is done in one go.

   "Arrived at position!"

   "+1"

   "I'm fine too!"

   They have cooperated countless times like this. According to the green dots on the VM map, the five-member team spread out evenly around the building, controlling all possible approaching directions.

   Almost no dead ends!

  The members of the cattle and horse team nervously waited for the start of the battle.

  However, after a long time, the street was still silent.

   Still no sound at all.

  Standing in the front row with Lao Bai, Quit held his breath and carefully observed his surroundings.

  However, except for the vines swaying gently by the window and the leaves shaking in the breeze, there is no obvious movement on the whole street.

   Is it an illusion?

  As soon as such a thought came into my mind, there was a whoosh sound above my head.

   Before everyone could speak, something exploded above their heads.

boom-!

  Ye Shi, who was standing behind the half-collapsed concrete wall, froze for a moment.

   "Fuck?! Mortars!"

  In fact, the combat efficiency of mortars in street fighting is very poor, and there are bunkers everywhere, and the fragmentation damage range will be extremely limited.

   However, the other side didn't seem to realize this, and then fired three shells at them.

   These shells exploded in the air without exception, and they were all twenty meters away from them!

   "And it's an airburst bomb..." Kuangfeng frowned, glanced at the signal on the VM screen, and then quickly glanced out the window, narrowing his eyes slightly.

   A grain of tiny fibers slowly falling from the air, they are like cilia on a dandelion.

   That is the culprit of blocking the signal!

   "It's a signal jammer!"

  Ye Shi's scolding came from afar.

   "Fuck! I said why the drone can't move!"

The latest "Five-style" light cavalry exoskeleton sold in the NPC store is not only equipped with a tactical helmet with eyepieces, but also includes a palm-sized small close-range reconnaissance drone mounted on the shoulder, which can share the field of vision with yourself or Teammate's helmet visor.

   But now.

   Drones lose their meaning.

   Not only Ye Shi’s drone was useless, but also the “Y-1 Firefly” quadcopter of Kuangfeng was also useless.

  Old Bai turned on the speaker of the helmet and shouted loudly.

   "Ye Shi, look for the commanding heights, find out the observers and destroy them! Quit smoking and follow me, we will find a way to end their mortars!"

  The advantage of the language barrier is fully displayed at this moment. They can't understand the words of the NPC, and the same NPC can't understand their communication.

"receive!"

  Smoking Quit was about to get up, but at this moment, thick tongues of flames suddenly shot out from the window directly opposite the street, and bullets shot over like raindrops.

  A piece of debris exploded on the concrete slope, and Quit was so frightened that he quickly buried his head and hid behind the bunker, moving low amidst the chaotic gunfire.

   Seeing that his teammates were suppressed by firepower, Lao Bai immediately raised his rifle and fired at the window directly in front to cover his teammates' transfer.

  At the same time, there were also intensive gunshots from the other side of the street.

  There is the direction of the strong wind and square length!

  Old Bai frowned.

  The combat quality of these people is not like a motley crew!

At least-

   Much better trained than those marauders!

   "Free Fire!"

   Shouting loudly, Lao Bai emptied the last shuttle in the magazine towards the window across the street, replaced it with a new magazine and began to move towards the outside of the bunker.

  The mortar on the opposite side continued to fire, and soon the signal in this block will be completely isolated from the outside world. Ye Shi is moving towards a higher place, and the area above the 20th floor should be able to resume communication with the shelter.

   At the same time, Fang Chang and Kuangfeng had already approached the enemy.

  The four-person team approached from their flanks and hit them in the face. The sprayed gun flames flickered and moved in the narrow alley, and the whole street was full of gravel and soil debris.

  There is no communication between the two parties.

   A fierce exchange of fire broke out in silence.

  Two shots were shot in the chest, but fortunately they were blocked by bulletproof panels. Fang Chang gritted his teeth and let go of the PU-9 submachine gun that was emptying bullets.

   Bullet Time!

   The flying dust suddenly slowed down.

   The whole world slows down together.

   Including himself!

   Locked on the figure in the smoke, he pulled the bowstring as fast as he could, and let go of his fingers.

  The bowstring trembled at a frequency visible to the naked eye, and the three-edged arrow shot out with full power sank into the smoke like lightning.

   Meanwhile, bullet time lifts!

  whoosh—

  The black shadow's chest collided with Fang Chang's charged arrow, and with a muffled grunt, he fell back and fell to the ground.

   Seeing the jet-black armor on the man, Fang Chang's eyes flashed with surprise.

  Who are these people? !

  …

   Reached out and dragged the teammate who fell to the ground with the arrow back to the back of the bunker. Dimit, who was holding an assault rifle in his hand, was also full of surprise.

   It's not surprising the identities of these people, their goals are very clear, and they know who these people are. However, to his surprise, these people's equipment and combat awareness completely exceeded their expectations.

   Pre-war police exoskeleton!

   Where did they get all these goodies! ?

   But whoever they are, don't try to slip away today!

   "The left lung has been pierced! LaVine is dying!" shouted the medical soldier handling the wounded.

   "Hemostasis spray! Quick! Help him deal with the wound first!"

   "These savages... are using bows and arrows?!" As soon as a soldier finished speaking, a shuttle of submachine gun bullets flew past his head, scaring him to hide in a hurry.

   "Don't underestimate them!" Dimit shouted loudly, "The bow in that man's hand is weird!"

  Helmet Aim Assist?

   Or electronic eyes?

   This reaction speed is a bit too fast!

  Especially the fact that this group of people saw through their ambush in advance, which caught him by surprise.

  Their exoskeletons can shield the heartbeat and 90% of the heat source. Even the Awakened Ones of the Intuition System can’t detect them at such a long distance, right? !

  Dimit pulled a fragmentation grenade from his waist, but before he could pull the ring, a whoosh broke through the air and exploded above his head almost at the same time as the explosion.

  Hundreds of steel **** exploded from the arrow, sweeping across a cylindrical surface, and they were caught off guard while hiding behind the cover.

  Thanks to the exoskeleton on their bodies that prevented the flying shrapnel, otherwise this arrow would have killed and injured most of them.

  Dimit didn't dare to take it lightly, and immediately clenched his fists, signaling to the two teammates who could still fight, to spread out the surrounding ruins on both sides, and bypass the opponent's dense firepower area.

  While the hearts of the group were shocked, Fang Chang, who shot the arrow, was also full of surprise on his face.

   It's okay to be shot by a bursting arrow from him?

   Good guy.

   Then come again!

   Without hesitation, he drew another bursting arrow worth 50 silver coins and put it on the bowstring. Fang Chang was about to charge up and shoot when the strong wind next to him patted his shoulder.

   "They got it!"

   Fang Chang's expression changed slightly, and he said decisively.

   "Retreat!"

  …

  The browsing room on the B4 floor of Vault 404.

  The digital screen next to the wall is simulating the flames of the fireplace, making a peaceful crackling sound.

  The environment here is really good.

  The only disadvantage is that it is easy to forget the day and night.

  Chu Guang did not go outside to inspect today, but sat on the soft sofa, flipping through the popular science books he took off the bookshelf.

  The name of the book is "Past, Present, Future".

  Some of the things mentioned in it, although they are only superficial descriptions, still opened Chu Guang's eyes.

   "As early as the 20th year of the Prosperity Era, the research ship of the People's Federation has explored all the planets in the solar system, and started the exploration plan of Nanmen 2."

   "Until the 30th year of the Prosperity Era, the South Gate 2 exploration plan has been initially completed, and the first colonial ship of the People's Federation has successfully left the port..."

   "Nanmen 2 must be 4.24 light years away from the earth."

   "Is this the mastery of faster-than-light navigation?"

  When his eyes stopped on a certain line of description in the book, Chu Guang had a weird expression on his face.

   “…a gravitational bond?”

  According to the description in the book, in the Era of Prosperity, physicists of the People's Federation discovered that there is a "gravitational bond" between two massive celestial bodies.

   Aerospace engineers call it the "gravitational channel."

Although it takes hundreds or even thousands of years for the spacecraft to fly from the solar system to other galaxies in the classical movement mode, no matter what things are used to accelerate the spacecraft, if the gravitational channel is used, the spacecraft only takes a relatively short time, It can "jump" between two massive star systems.

  Generally speaking, the time taken for the transition is proportional to the mass of the spacecraft and the distance from the celestial body, and inversely proportional to the mass of the celestial body. There is a specific formula that can be calculated.

  According to this formula, the jump between the solar system and the Southern Gate II system will be faster than the jump between the earth and Mars.

   Yes, there are many gravitational channels.

  It can exist between star systems and star systems, it can also exist between planets in star systems, and it can even exist between star clusters and star clusters. It's just that due to the problem of the jump point, almost 99.99% of the gravitational channels are useless even if they exist.

Fortunately, the physicists of the People's Federation have solved this problem. They not only calculated the method to determine the course of the gravitational channel, but also summed up the formula for calculating the jump point, so that the People's Federation can use the gravitational channel to carry out "hyperspace navigation" became possible.

   And this also laid the foundation for the continuation of the prosperous era.

  Controllable fusion solved the energy problem, and the discovery of the gravitational channel made it possible to colonize the outer solar system, and at the same time solved the two problems of matter and living space.

  Human civilization also ushered in the first "ascension" and took the first step from the interstellar natives to the star sea overlord.

  Honestly speaking, this popular science book writes this section like a cool article.

  Maybe considering that the audience of popular science stories is children, the colony cabin sailing to South Gate 2 is simply described as a paradise on earth.

   As for now...

   It's more like after a failed robbery.

   Not only was "all power lost", but the entire People's Association was completely annihilated.

  Chu Guang now somewhat understands Yin Fang's feelings.

  The more you know, the easier it is to feel confused about the future.

   "Nimma..."

   "It would be great if we traveled a hundred years earlier!"

   Ask if you don’t understand, is it too late to drink fake wine?

According to the book "Past, Present, Future", if you travel to the early or even middle period of the prosperous era, as long as you don't go to the dormant cabin to do "time travel" or "want to see the future", you will die. It may not be possible to see the collapse of the prosperous world.

  Chu Guang turned a page backwards.

It is a pity that this popular science book does not give a detailed explanation of the "gravitational bond", just like most popular science books in the parallel world will not fully paste the derivation process of the theory of relativity, but generally summarize it as "Finding shortcuts from hyperspace".

   Hyperspace Chu Guang still understands a little bit, literally means multi-dimensional space.

   And this is what surprised him the most.

   In "modern physics", force is usually explained as the process of collisions between the particles that make up matter and the particles that transmit the force. Under such a framework, the four fundamental forces, except gravity, can be explained and calculated consistently, and agree with the experimental results.

   This is the "Standard Model".

   is also the cornerstone of modern physics.

  However, this model is not perfect, just like Newton’s classical mechanics cannot explain the laws of motion of massive celestial bodies, this model also has limitations of the times—it cannot be perfectly compatible with gravity.

  So someone put forward the "string theory". Under this conjectured theoretical framework, the three basic forces are interpreted as open strings, and gravity is interpreted as closed strings.

  Based on this conjecture, gravity can transcend all dimensions.

   The physics of the two worlds seem to be connected?

  Although it is only a conclusion of two sets of theories.

   Staring at the line of description in his hand, Chu Guang suddenly thought of the recordings that were unlocked on the B2 floor, and the part about the morphological field mentioned in it.

  “… There can be a gravitational bond between star clusters and star clusters, so is there a similar bond between universes?”

   Chu Guang is unclear about the mass of the universe. This thing is like oil reserves. With the advancement of exploration technology, it may "dig more and more".

  But assuming that the mass and distance of the two universes are both infinite, Chu Guang tried to bring in the simplified formula mentioned in popular science books, and the obtained mass of the spacecraft m is infinitesimal.

   In other words, according to the theory of "gravitational bond", even if there is such a bond between two parallel worlds, it cannot allow even a single quark to pass through it.

   But what about particles with "0 rest mass"?

   Such as photons.

  The transmission of information requires a carrier, and the ability to exchange carriers means that the transmission of information is possible. As for what this medium is, I am afraid that only physicists in the Renlian era can answer.

   "The morphogenetic field connecting parallel worlds might be based on a similar theory."

   "How is the parallel world positioned?"

  Chu Guang gently closed his eyes, digesting the knowledge he had just absorbed for a while.

  The intelligence of 20 points played a little role.

  If he was not a manager, he might be able to become an astonishing physicist in the parallel world Earth.

  At least the content of this book alone, if he updates the database on the official website, it will be enough to set off an earthquake in the physics community of the parallel world.

   Maybe you can get a Nobel Prize.

   But this is ideal.

  The Earth in the parallel world does not have the ability to verify these theories, and the superficial descriptions in popular science books are not enough to serve as rigorous scientific conclusions, at most they serve as a "correct direction".

  As for myself, there is a high probability that I will be regarded as the messenger of "advanced civilization", and this popular science book will also be regarded as evidence of "advanced civilization's good intentions to enlighten earth civilization".

   So here comes the problem.

  How many silver coins should this book sell for?

  Thinking of Brother Fengfeng in the server, Chu Guang couldn't help but smile.

   "Let's upgrade well."

   "When you help the manager revive the People's Federation, I will give you the title of Chief Physicist of the Earth Federation to enjoy yourself, and how about giving you a few Nobel Prizes by the way?"

Of course.

   If you can't bear it, don't blame your brother.

  Chu Guang turned down a page with a smirk, and at this moment, Xiao Qi's voice suddenly came from the side.

"Owner."

"What's wrong?"

   "Your Burning Legion signal has disappeared from the map."

   What the hell? !

   Shocked, Chu Guang quickly closed the book in his hand and put it aside, picked up the tablet on the table and opened the map without saying a word.

  Five green dots have disappeared from the east side of Qingquan City.

"system!"

  A light blue window appeared in front of his eyes, Chu Guang directly cut to the player list, saw the online icons of several players, and then he breathed a sigh of relief.

   It was only the radio communication that was disconnected, not the morphing field!

  Clones are still alive!

   It should be some kind of signal jamming device, blocking their signal.

  Although there is the possibility of accidents, the safety of the fuel rods is related to whether the No. 401 shelter can be used, and no accidents are allowed in this matter.

   It only took a second to make a judgment. Chu Guang stretched out his index finger and tapped on the tablet, and clicked to send the "pre-edited" task command.

   "Let the mosquito planes go and see!"

  Xiao Qi's energetic voice came.

"okay!"

  At the same time, the runway in the north of Dawn City.

  A wooden plane turned its propeller and slowly opened the hangar door.

   The mosquito who was teaching his apprentices how to operate the glider a minute ago jumped into his car without saying a word, and put the pilot hat made of dog skin on his head.

  The two machine guns on the plane have been replaced by 10mm Maxim-II from 7mm small water pipes, and the entire wooden glider has completely changed from a reconnaissance aircraft to a ground attack aircraft.

  The mosquito drew a shark tooth on the nose with paint, and the whole nose looked like a shark with its mouth wide open.

  Although the skin does not add attack power, it looks cool.

  Who will dare to say that he licks the floor like pee in the future!

   "Practice by yourself! You can play whatever you want except don't go to heaven!"

  The four training planes are not equipped with weapons, so it is useless even if they go up.

  However, when they heard this sentence, the four apprentices were instantly unhappy.

  Deadly: "Damn!"

  Chasing the soul: "What the **** are you eating alone again!"

  Shashen: "Come down and I'll drive!"

   Persuading the fight: "%￥#@!"

   "Football, can I do serious tasks for you? Go to reality to test for a certificate first!"

  Deadly: "You have a certificate?!"

  There were not many mosquitoes beeping, he smiled and pushed the switch to the bottom, pulled up the joystick the moment it reached the take-off speed, and lowered the visor of the helmet at the same time.

   The task is simple.

  Cruising in the east area of ​​Qingquan City, searching for the signal of Lao Bai and the others in the air.

  Back up if something unexpected happens.

   If it is safe to do so, scout out where they are headed before the energy runs out.

   Intuition tells Mosquito that this kind of task is generally spawned, and the second situation can basically be ignored. Don't even think about it, it's probably true!

  The entire team disappeared from the map.

  The background of the enemy is probably not small!

  Blood surged all over his body. Although there was still a distance of more than ten kilometers, the index finger of the mosquito had already touched the safety of the fire.

   "Brother Meng!"

"wait for me!"

  …

  East District of Qingquan City.

   Gunshots sounded like firecrackers.

  Letting Quit stay in place to restrain the machine gun on the opposite side, Lao Bai went around to the flank and planned to get rid of the annoying mortar first.

  However, when he arrived at the location, he realized that things were not as simple as he thought.

  I saw a heavy-duty exoskeleton standing in the center of the flower bed in the community, with two armored arms supporting the ground, as if running up, and the gun barrel raised on the back fired continuously.

  Every time a shell is fired, a cloud of dust will shake up on the ground.

   What the **** is a mortar.

   It’s clearly an exoskeleton version of a self-propelled artillery!

  The three exoskeleton soldiers guarding the "self-propelled artillery" immediately spotted Lao Bai the moment he appeared, raised their rifles and fired at him without saying a word.

   Almost got swept away, and Lao Bai, who was hiding behind the residential building, immediately shot back with his gun out of the cover.

   However, the opponent was obviously not a vegetarian. Three assault rifles fired at the same time, and the ferocious firepower suppressed him back.

  The three exoskeleton-wearing soldiers didn't stop there, they formed a triangle with tacit cooperation, and fired alternately towards him.

  Looking at the crack in the bulletproof plate of his left arm, Lao Bai gritted his teeth and replaced the clip, and began to move towards the half-collapsed building next to him.

  There is no signal in the entire area. It should be the dust from the jamming bombs being blown over. Now he doesn't even know whether his teammates are dead or alive.

   Fortunately, the gun barrel on the back of the heavy-duty exoskeleton has ceased fire, so the pressure on Fang Chang and the others can be reduced.

   "Damn... where the **** did these people come from!?"

   Could it be that Fang Chang was targeted by the planner for smashing the goods and shipping them?

   Can't it? !

  They are not the only ones cutting leeks.

   Just when Lao Bai was secretly surprised, there was a gunshot in the distance.

   Of the three exoskeleton soldiers chasing after him, one of them was shot sideways, the bulletproof plate cracked, and he almost fell to the ground.

  The teammate next to him immediately grabbed the man and pulled him into the next bunker. Forced by the deterrence of sniper rifles, they dare not come out of the bunker, and can only detour through the ruins with a narrow view.

"pretty!"

  Old Bai was overjoyed, he didn't miss this once-in-a-lifetime opportunity, and immediately counterattacked, suppressing them who were about to make a detour.

  The two sides have reached a stalemate!

   Leaning against each other on the bunker, they put cold guns.

  However, what made Lao Bai's heart sink was that the "self-propelled artillery" started firing again.

   And this shell directly hit him ten meters sideways!

   As a last resort, Lao Bai had no choice but to give up the suppression of the three exoskeleton soldiers and retreat to the building across the street from the community.

  Ulen, who was crouching behind the bunker, changed the magazine, gritted his teeth and led two teammates to catch up.

  The other party's difficulty exceeded his expectations!

  There is no news from Dimiter's side, and someone actually bypassed their front and penetrated into the mortar position 600 meters away from the firefighting area.

   Tapped his index finger on the helmet of the exoskeleton, Uren had an idea, and shouted loudly.

   "Surrender! You are surrounded!"

   "We will not kill you, as long as you are willing to hand over the black box you stole from us!"

  The sound echoed in the street.

   Lao Bai, holding an assault rifle, frowned.

  What is this guy talking about?

  His human connection language is not as good as Fang Chang, and he can jump a few words. Sometimes it's okay to speak slowly, but he becomes confused when he speaks fast.

  However, if you don’t understand it, you don’t understand it, so you can’t be weak in momentum.

  Old Bai imitated the pronunciation of the other person, and returned the sentence intact.

   "Surrender! You are surrounded!"

  Uren: "???"

   It's okay that we're surrounded.

  Is this person hallucinating?

  However, just when he was thinking this way, there was a piercing scream in the air.

  Ulen looked back suddenly, and saw a "shark" with its **** mouth wide open, roaring towards the mortar positions behind them.

   There was a flash of fear in his eyes, and he roared out of his voice.

   "Ted! Get out of the way!"

  Ted, who was wearing a heavy-duty exoskeleton, apparently also noticed the abnormality in the sky, and quickly retracted his arms inserted on the ground.

However-

   It's too late!

  Two 10mm machine guns sprayed flames from the shark's **** mouth!

   "Ah da da da! Go to hell!"

   Outputting firepower with its mouth, the mosquito trembling with the cabin, excitedly pulled the trigger to the bottom, and swept the exoskeleton carrying the gun barrel with the front sight.

  Although the body is covered with bulletproof plates, the exoskeleton is an exoskeleton after all. No matter how many bulletproof plates are hung, it cannot stop the firepower of the fixed wing.

   Facing the random sweep of two 10mm machine guns, in just a few seconds, the heavy exoskeleton was smashed into a sieve.

  Sparks half a meter high erupted from the ammunition box and the battery in an instant, and the man was blown to pieces together with the armor on his body before he could even utter a scream.

  The plane regained altitude and flew towards the sky.

"asshole!"

   Staring desperately at the plane, Uren's eyes were bloodshot.

  His teeth were almost shattered, and his index finger pulled the trigger to the bottom, emptying the entire clip of bullets, and did not stop until the plane disappeared from view.

  The same goes for the other two teammates.

   Anger nearly drove them out of their minds.

  However, as the captain of the team, Uren's remaining sanity finally calmed down quickly.

  The opponent has air support!

  Although it is just a ridiculous propeller plane, those two heavy machine guns are not a joke, and their equipment has not advanced to the level of counter-common sense.

  This is the valley province far away from the coast of death. It is just at the door of the other party. The supplies and reinforcements on the opposite side are almost unlimited, but there are no supplies and reinforcements available on your own side.

  Thinking of what the man said earlier, Ulun's heart sank even more.

   Maybe that person wasn't joking.

   The reinforcements of these people have really surrounded them!

   They only have one chance!

   If they can't catch anyone, they can only adopt plan B and continue north to seek help from the raiders they have funded.

  With no time to hesitate, Uren immediately pulled out the flare gun on his waist and fired a flare into the sky to alert his teammates in front.

   Immediately afterwards, he shouted at the two teammates beside him.

   "Withdraw!"

  …

  The battle is over.

  The other party gave up their position and retreated back into the ruins.

  The mosquito circled several times in the sky, but finally failed to find a second chance to dive. After confirming the safety of its own people, it began to return.

  Smoking Quit took the box containing the fuel rods, first joined with Guafeng and Fang Chang, and then moved towards the direction of the signal flare for reinforcements.

   Here they met Lao Bai.

   "Fuck?! Are you okay?" Looking at the torn bullet-proof plate on Lao Bai's chest, Fang Chang's face showed a surprised expression.

   "Don't worry too much, you just got shot seven or eight times," Lao Bai removed the sagging bulletproof plate, and said with emotion, "If this happened in reality, I guess it would be gone."

  Guang Feng coughed lightly.

   "No need to estimate, just be more confident."

   Quit smoking nervously.

   "Do you want to chase?"

  Old Bai shook his head.

   "Chasing the hammer, the mission is urgent. Call Ye Shi back, and we're on our way quickly... If they have reinforcements, we'll be in trouble!"

  How to chase?

   Up to now, their VM signal has not been recovered, and the opponent has already retreated into the ruins.

   You can't leave the fuel rod here.

  Looking at the heavy exoskeleton not far away, Fang Chang stepped forward and pulled the charred corpse out of the armor.

  Fumbled around the corpse for a while, Fang Chang's hands stopped suddenly, and he took out a necklace from the neckline, with a burnt iron plate strung on it.

  There is a torch engraved on it.

   "Did you find anything?" Lao Bai came over and asked.

"Um."

  Fang Chang nodded and shook the iron plate in his hand.

   "The emblem of the torch... has his name engraved on it, but I don't understand the words."

  Looking at the burnt black exoskeleton wreckage, Lao Bai took a signal flare from his waist, pulled off the ring and threw it beside the exoskeleton wreckage.

  The signal flare emits billowing red smoke.

   "Leave this to the NPC."

  Old Bai patted Fang Chang on the shoulder.

"let's go."
