"Everyone, this time the mission is to revolve around ‘rescue’. This is also our purpose when we first left the home planet..."

　　 After several years, relying on a giant tool called a space battleship, which can be called a miracle, across the long distance between the stars, aliens came to their battlefield.

　　 Now, Bocaul, commander of the Fourth Fleet of the Empire, is doing the final war mobilization.

　　 "A thousand years ago, the empire defeated the world! Achieved global unity!"

　　 "Five hundred years ago, the empire defeated civil strife! The shadow of the imperial empire dissipated!"

　　 "Four hundred years ago, the empire defeated the famine! No one will be hungry again, no one will be trapped for survival!"

　　 "Three hundred years ago, the empire defeated resources! The progress of industry allowed us to end the long construction period of the first mothership class!"

　　 "Ten years ago, the great plague was rampant, and the empire won! We developed biology, and we defeated the disease! In the future, we will get ‘longevity’ thanks to this technology!"

　　 "Now the empire is facing new enemies, new challenges, this time...we will win again!"

　　'S impassioned words inspired the morale of the Fourth Fleet, the flames in his heart were gradually ignited, and every alien was full of blind confidence in this battle.

　　 Standing Bokauer leaned down, and in front of the captain's seat was a three-dimensional structure of the starry sky battlefield, with various geometric coordinate systems marked in it.

　　 A standard space combat simulation sand table.

　　 Bokauer stared at the phantom of the planet in the projection, and released the final speech.

　　 "For the empire, crush them!"

　　 A strong sense of war filled the hearts of every imperial warrior, and the excitement even caused a slight gradation of their skin color.

　　 "Crush them!"

　　 "Crush them!"

　　 Warships ‘departed’ from the mothership class, battleships, escorts, supply ships... the size of the fleet is expanding at a speed visible to the naked eye.

　　The unfolding battleship group can be roughly divided into three categories based on its role, long-range firepower, close guards, and transportation supplies. These ships are centered on the mothership class.

　　 "Deliver ground combat units."

　　 "Long-range firepower ships provide fire cover, pay attention to the firepower density and the position of the bombardment, and do not harm the colony."

　　 "The **** ship pressed forward on the front line and cooperated with the autonomous ship to build an interception net."

　　 "Pay attention to each mothership and prepare for recharging."

　　...

　　 Quantum-encrypted electromagnetic wave commands flood the Fourth Fleet’s local area network. The entire fleet is like a huge machine at the moment. Each ship is like a part of it, faithfully playing its role.

　　 battleships, cruisers and other long-range firepower ships' bow valves slowly opened, revealing their black hole shaft gun muzzle.

From the side, the long-range fireship stretches out a huge plane, the area of ​​this plane has reached the same level as the hull, and it is completely facing the direction of the star. If it is close enough, you can occasionally see the blue arc flashing on the plate from time to time. .

Under the action of the internal magnetic field, one projectile leaves the barrel at a very high speed, one after another, without friction and no secondary effects. This provides the foundation for the continuous firing of electromagnetic railgun projectiles. The earth In those film and television works, the scenario where the main gun needs to be cooled after firing did not happen.

A large number of long-range fireships repeat similar things. Countless projectiles form a "wall", not a densely tangled solid wall. The principle is similar to that of Saturn's rings, and it only appears under the refraction of stellar light. 'wall'.

　　 But, even so, it is quite spectacular—imagine a planet-scale piece of paper slowly approaching the surface.

　　 is on the surface, whether it is a colony of aliens or Hogu, they rely on tools or their own observation capabilities to capture the abnormality from the stars of the universe, and at the same time, they also understand what it means.

　　 The first wave of offensive of the Fourth Fleet!

　　 Huogu, of course, can’t sit and wait for death. The enemy has already fired. If he doesn’t respond, he is at the mercy of others.

　　The honeycomb on the surface uses electromagnetic wave radar to lock the projectiles approaching at high speed and calculate the trajectory of the projectiles. It also relies on the magnetic railgun to launch projectiles into outer space.

　　 The ‘Meteor’ dragging a long trajectory due to friction with the atmosphere quickly met the projectiles fired by aliens in the gravity-free space of space.

　　 There are no gorgeous explosions, no shrapnel splashing around, only a very dazzling light, and a dusty residue that remains.

　　 [That is... so it is. 】

　　 This is an abnormal phenomenon, which naturally aroused Min's interest. After careful observation, Min understood the reason for this phenomenon.

　　 "Did you see it?"

　　 Huogu’s mood swings revealed an ‘accident’. It was able to see the principle of the alien weapon at the beginning, but it was also due to the information obtained by the collectors who sacrificed their lives to test.

　　【Using a certain fixed frequency vibration to break the molecular bonds, this causes this phenomenon in the macroscopic view. 】

　　 [Those guys are very clever in the use of ‘frequency’. 】

　　 "It's really a shame that you can see at a glance, UU reading www.uukanshu.com, the general principle of the alien weapon called ‘sonic boom’, do you know the specific details?"

[I can’t see it. In theory, this should not make sense. Let’s not talk about how to solve the large residue if the substance is broken from the internal molecular bonds first, just say what is needed to break almost all the molecular bonds of the target. Energy, I don’t even know where it comes from. 】

　　 "Of course it's nuclear energy. If you rely on chemical energy, it can't be of this size, and the strong light of those shells has already explained the problem."

　　 "I guess the aliens should achieve the kind of effect by spreading most of the energy of the nuclear explosion in the form of that wave frequency."

　　 "It's just that, how do they ensure that the frequency wave can be completely diffused? I haven't figured it out yet, otherwise I want to come out in a batch."

　　 Huo Gu is also very helpless about this, and can't use it if he doesn't understand it.

　　 is like a nuclear bomb. Although it is extremely powerful, it is very safe. As long as it does not reach the right temperature and pressure, even if the nuclear bomb is rolled from the top of the Himalayas to the foot of the mountain, there will be no nuclear explosion.

　　Long defense must be lost. What's more, the aliens didn't expect these ‘popping’ shells to break through the enemy’s blockade at the beginning, it was just a feint to attract the enemy’s attention.

　　 The real killer moves are those ground combat bodies hidden in the dust residue.

The 　　 optical gradual camouflage system is very good to give the combat body a certain degree of "stealth", coupled with the dust residue that could interfere with radar detection, they successfully concealed Huogu's eyes.

　　 When entering the planet, these combat bodies are exposed to Huogu's vision due to the trails that are exhibited by friction with the atmosphere.

　　 However, it was too late to take countermeasures at this time. The huge base number destined Huogu to be unable to stop all the ground combat bodies that were landing.
