A mechanical arm glowing with icy luster stretched forward, picking up a rough green crystal from the sealed vessel. At the other end, the laser transmitter emits a beam of icy light, cutting the rough stone at a precise and accurate angle. After a while, a spar with a perfect six-sided shape appeared on the robotic arm. It shines with green light. When a beam of blue light shines in the middle of the spar, the spar refracts countless interlaced green light beams in all directions, spreading across the entire vessel, blooming with dazzling light.

"This is……"

When the light in the vessel converges and disappears. Merlin took off the goggles and looked at the scholar Rhodes who was in charge of the new energy development project nearby. Rhodes nodded and said: "As you can see, this is the new element that replaces the sky stone. It can produce pollution-free clean energy through cutting and particle acceleration. It can replace the sky stone, but its energy intensity Only about 55% of the Sky Stone. Therefore, the Nethresian Shield after reducing its energy can only compensate for the lack of purification range through quantity."

"These are not problems, Rhodes. With the processing technology of Dawn City, they can mass produce reduced versions of the purification device." Ademili will send it to Dawn City."

"Speaking of which, the name of this new element has not yet been named."

Merlin thought for a while, then said solemnly: "Just call Yasuo."

"Yasuo... hope? It's really an appropriate name." The scholar whispered.

In the language of Ludu, Yasuo means hope. The advent of Yasuo Spar will completely change the entire world. This kind of spar is not a natural product, but is obtained by pulverizing, melting and synthesizing several kinds of ores. Finally, as long as it is cut into a perfect six-sided shape according to the correct method, it can be used as an energy source for the Nethrace shield.

As for the raw materials of those ores, they are not rare products, so Yasuo spar can be produced in large quantities. Although in terms of the consumption level of ordinary industrial products, its loss is still a bit larger, reaching 33%. However, as a valuable energy source that can replace Sky Stone, this loss is completely acceptable. What's more, this technology can be further improved, or find other more efficient synthetic materials, in order to reduce consumption.

In short, with Yasuo Spar, at least the energy problem of the Nethrace Shield has been solved. It is conceivable that when this kind of purification device is no longer subject to energy constraints, it can enter the factory assembly line for production. It will not be long before life on Earth can live on the surface under the protection of the Nethres Shield, instead of hiding in underground bases or other harsh environments.

Even the earth's environment has been improved for this, thus ushering in a new era!

When she walked out of the laboratory, Merlin felt that today's world was completely different. But the Red Duke did not know that the crisis was approaching step by step. When Merlin strode to the temple and wanted to tell Ademili the good news, it was located five hundred kilometers away from the Green Capital, and a paw covered with light armor was pressing against the green moss lichen spreading over the ice field.

The soft lichen sank the paw slightly, a guard lowered his head, and after a flash of three pupils, he whispered behind him. Then only black guards rushed past it, and from the sky, a black wave quietly poured into the dark green ground, continuing to move in the predetermined direction. But the guards also didn't know that the moss coats all over the tundra under their feet were not natural plants, but a warning system specially erected by the green capital.

The moss clothing was pressed, and their rhizomes soon showed a special tremor. The encrypted signals spread through the roots in the ground, and were quickly fed back to the information room of Ludu. A special alarm that would only appear when an intruder was found in the intelligence room immediately sounded, which made Supervisor Raven jump up.

"What's the matter?" Raven called.

"It seems that the monitor has found the intruder, and now the returned picture is being analyzed. Okay, please see it, adults."

A staff member tapped the light key under his hand at extremely fast speed. Soon, guards appeared on the main screen of the wall. Seeing these quiet and rapidly advancing biological weapons, Raven almost screamed: "Quickly, invite Master Merlin."

Ten minutes later, both Merlin and Ademili appeared in the intelligence room. Looking at the black biological weapons in the picture, Merlin's face was heavy. Ademili looked at the Grand Duke and said solemnly: "Hamemis once said that once the mother wakes up, the black wave will flood the earth."

"Do you think this is the biological army of that thing?" Merlin asked rhetorically.

Ademili looked at the screen: "Look at them carefully, Merlin. They are almost the same. There is no communication during the whole process, which means that they have received some kind of order. If these things are not biological weapons, please Tell me what they are?"

"Okay, **** it. Raven, do you know how many of them are?" Merlin said loudly.

Supervisor Raven threw himself in front of the workbench, waving his hands continuously, after a moment. He raised his head, his face was ugly, and said: "According to the feedback from the monitors, the number of them is at least 30,000."

"Masters, look at these." A staff member called out suddenly.

The picture on the main screen changed again. This time, it appeared on the screen as the Scarlet Guards flapping their wings and flying at low altitude. There is no doubt that these red guards are the elite of the biological army. When Raven reported the number of thousands, Merlin even breathed heavily.

"How long will they arrive?" Merlin asked.

"Less than 36 hours!"

"Time is pressing." Merlin looked at Ademili and said, "It seems that you have to leave early. I asked the people on the new energy development team to speed up. After all the information is sorted out, you will immediately take it to Dawn City. And tell zero about the situation here. Ademili, ten hours at most. At that time, you must leave."

"And you?"

Merlin looked at the screen and said, "Someone has to buy you time. If these guys catch up with you, our hope... No, the hope of this planet will disappear. Remember, you have to use the fastest Speed ​​away."

Ademili sighed softly, but nodded.

Merlin said to Raven again: "Go and inform other cities in the Federation to send troops to Storm Fortress. If we are finished, we need a second barrier to stop these black guys."

On this day, the whole green is boiling. The army needed to be mobilized, the civilians began to retreat, and Merlin himself sat alone in the temple. He sat on the ground, looking at the throne where Hamomis had been arrogant. The flames lay down on both knees, and Mei Lin sighed slightly: "My lord, maybe this time, I can't keep this city."

The wind blew into the temple, with a low echo, like a sigh of Hamemis.

In Ludu, civilians and soldiers are equally busy. The former organizes his own clothes and prepares to leave the city where he was born and grew up. The latter carried all kinds of ammunition out of the warehouse, or inspected the power mechas to ensure that they would not have any accidents during the battle. There is still more than a day before contact with the Black Legion, this period of time is neither long nor short, just enough green to deal with it.

This is due to the green moss coats that have paved most of the tundra. If it weren't for them, it would be too late for Green to discover the Black Legion.

The hustle and bustle of the city lasted from day to evening, when a group of civilians began to leave. Merlin drew an army of five hundred people to **** them, and Ademili would also leave. But before setting off, she came to the temple. Taking a deep breath, she pushed the door of the hall open. The moment the door opened, she even had an illusion, as if Hamomis was still sitting on the throne of the temple.

If Hamomis never left, would it be another situation at this moment? Ademili did not seek the answer to this question, because the world has always said if it is.

The majestic back of Mei Lin was reflected in Ademili's eyes. In him, Ademili saw many things. The Red Duke felt her coming, but he didn't even look back for a moment.

"I gotta go."

"I know."

"Will we meet again? My friend." Ademili said softly.

A smile appeared at the corner of Merlin's mouth: "You know the answer, so why ask me. Let's go, Ademili. Take ours and the hope of the world and leave here. Lord Hamomis, Ludu Well, we have all fulfilled the mission given by the times. Even if it disappears, it has never been a good thing. Adults have foreseen this from a long time ago, have they not?"

"I understand. Then you take care, Merlin." Ademili took a deep look at Merlin, as if to engrave his figure in his mind.

Another close relative is leaving, and Ademili's heart is slightly sentimental. She turned around, left, and walked in the opposite direction to Merlin. Life is on one side, and death on the other side!

Gradually, the hustle and bustle in the green city quieted down. The civilians have left, and now there are only 5,000 soldiers left in Ludu. In the evening of the second day, all the soldiers received the order to assemble. They stood in the square in front of the temple, quietly waiting for the arrival of the Grand Duke.

Merlin finally moved, holding the flame ruling, and stood up. Wearing the dark red armor components placed next to him one by one, when all the armors were worn, a sharp light flashed in Merlin's eyes and strode out toward the square.

Seeing the soldiers of the Green Capital standing upright like a javelin in the square, Merlin paused with the handle of the axe and said loudly: "I am very pleased to see that you have not flinched, the Warriors of the Green Capital!"

"Your chief should have told everyone about the specific situation, so I won't repeat it. What I want to say is that this battle will be extremely difficult, and I don't even know how many people will survive. I only know that we We must do everything we can, even at the expense of our lives, but also to keep those black guys. Otherwise, our people will die under their minions."

"Since they have given us their backs, we can't let those black monsters cross the line for half a step! Tonight, we will fight to the end!"

"Fight to the death!"

"Fight to the death!"

The soldiers of Ludu raised their weapons high and let out a continuous roar.

The sky light to the west finally fell into the ground, and night fell. The reddish sky light fell on this tundra like a tulle, covering all things with a faint blood. On the basin on the surface of the Green Capital, a ring-shaped metal defensive high wall is the artillery fort of the pneumatic cannon, which is connected by rails, which allows the pneumatic cannon to move and gather fire as needed.

The two hundred "predators" power mechas have been deployed to the ground, and the Ludu fighters are located in the garrison. When needed, they can quickly enter the surface to join the battle. Merlin stood alone on the tundra in front of the ring of forts, his battle axe hit the ground, and the wind blew the red cloak behind him, like a fire that never extinguished under the night.

The wind was blowing from the front, and accompanied by the night wind, there was also a slight vibration of the ground.

"Here," Merlin said softly.

Although in the vast night, the distant tundra is shrouded in a dim sky, nothing can be seen. But in Ludu's intelligence room, Supervisor Raven was able to see a large number of guards approaching through the monitors. Raven immediately grabbed the communicator and shouted: "They are here, they are here! We will enter the firing range of the pneumatic cannon in 10 minutes."

At his reminder, the fortress of the pneumatic cannon began to move. These large iron blocks gathered behind Merlin along the railroad tracks, the artillery fortresses were close to each other, and the muzzle of the muzzle adjusted its direction towards the distance of the tundra under the dark night.

On the left and right, the power mech walked out and came to Mei Lin's side, building a steel line of defense. More soldiers are in the military barn, waiting for the commander's orders.

Finally, something flashed under the night in the extreme distance. Merlin took a deep breath and snarled: "Batter me those bastards!"

"Pneumatic cannon, fire!"

"Fire!"

Suddenly, the artillery wall behind Merlin continued to roar. The muzzle of the wind-actuated gun was fine-tuned upwards. After the air compressor accelerated the airflow, it pushed the physical live ammunition to burst out of the muzzle. After passing the parabola in mid-air in a projectile mode, the flames fell from the sky, towards more than two thousand. The tundra fell away from the rice.

The first shell screamed down, and in the fire, you could see the scene of several guards raising their heads, and then everything was shrouded in the flames of the explosion. From a distance, the tundra exploded continuously from a kilometer away, and the expanding flames melted away, forming a fiery cloud of fire! In the fire cloud, a large swath of guards fell down, but more biological weapons passed through the fire curtain.

The black guards joined end to end, advancing rapidly in a flywheel mode. They whizzed sharply on the tundra, and the spinning bone spurs plowed the icy debris and moss of the tundra, and shuttled under the continuous bombardment of the green city artillery array. Advance. The Crimson Guards flew into the sky, their wings vibrated behind them, swept up to a height of more than ten meters, and then rushed to the green capital. So a red cloud suddenly appeared in the night sky.

"It's a flying unit, shoot it down! Shoot it down!"

The army barn opened, and a group of Ludu gunmen rushed out, occupying the top of the defensive wall, raising weapons like gunpowder rifles in the old times, but blasting high-energy beams from the muzzle. In front of the artillery formation, the powered mech also raised its arm, and the mech driver pressed down the firing button forcefully, so the six-barreled cannon hanging on the mech's arm also roared.

For a time, countless beams of light slanted up into the sky, along with the bright chains of fire blasted out by the machine guns, and blasted into the red clouds that floated from a distance. The Crimson Guards immediately dispersed their formation, they flexibly shuttled between the beam and the line of fire, but from time to time there were still guards hit and fell from the air.

Suddenly, the battle between the sky and the ground began at the same time, and the flames of the explosion almost illuminated a small half of the tundra.

After the black guard on the ground advanced another kilometer, the infantry soldiers in the military barn finally came out. Each of these infantry soldiers is carrying a thick-backed epee, and Baltimore, the head of the guard, holds two swords. Baltimore came to Merlin's side, his eyes fixed on the front. When the Black Guard advanced another 500 meters, the pneumatic gun had switched to flat-fire mode.

With such a bombardment, one explosion was enough to engulf hundreds of guards in the flames. But the wind-driven artillery array only had time to fire two more times, and the Black Guard had already advanced two hundred meters!

"It's time for us, do it hard, boys!" Baal Mo yelled at the infantry soldier behind him.

Merlin pointed his battle axe forward and shouted, "Mecha troops, fight!"

Immediately, the muzzle of the looters was pressed down, no longer paying attention to the Crimson Guards in the air, and instead focused their firepower on the ground. The powerful bullets of the machine cannon pressed over, and the powerful bullets blasted on the flywheel, immediately blasting huge wounds on them. The guard can't survive a few bullets, and he will be shot to death. For a time, the guard's forward fell down a blockbuster, and only a few flywheels were able to cross the firepower net.

The Baltimore epee vigorously swung down ~lightnovelpub.net~ and the roar of the infantry warrior sounded behind him. The crowds rushed from both sides of him and Merlin, slashing the thick-backed epee towards the flywheel that had crossed the firepower net. The fighters were in groups of four, and the epee slashed in one round, easily beating and tearing the guards to pieces. The firepower of the looters and wind-operated artillery continued to hit the Black Legion. Under the strong firepower of these weapons, only one or two guards could cross the firepower net.

This amount was quickly eaten by infantry soldiers.

But whether it's Baltimore or Merlin, they are quite aware that Ludu's advantage is only temporary. When the ammunition of the marauders and wind-operated artillery is exhausted, and there is not enough firepower to block the enemy's advancement, the situation will be reversed in an instant.

What's more, these black legions also have air support units, which are temporarily intercepted in the night sky hundreds of meters away. But once it gets close, it will also pose a threat to Ludu's ground troops.

Therefore, Lvdu's temporary advantage does not explain much. As Merlin predicted, this will never be an easy battle!

At this time, a strange howl suddenly sounded in the sky. But it was a ball of fire slanting down and smashing into the position of the infantry soldiers. In the bright flames of the explosion, at least a dozen soldiers fell to the ground. The Crimson Guard of the sky has already begun to pose a threat.
