An icy sheening mechanical arm stretched forward, clamping a rough turquoise crystal from the sealed vessel. At the other end, the laser emitter shoots out a beam of icy light, cutting through the rough at a precise and precise angle. A moment later, a hexahedral hexahedron appeared on the robotic arm. It shone with a green light, and when a blue light shone through the middle of the hedron, the hedron refracted countless staggered green beams in all directions, spreading all over the vessel, blooming with dazzling light.

"That's ......"

When the light in the vessel converges and disappears. Merlin took off his goggles and looked at Rhodes, a scholar in charge of a new energy development project next to him. Rhodes nodded, "As you can see, this is a new element that replaces the Sky Stone. It can be cut and then accelerated by particles to produce clean energy without pollution. It can replace the Sky Stone, but its energy intensity is only about 55% of that of the Sky Stone. Therefore, after reducing the energy, the Netheres shield can only make up for the lack of purification range through quantity. ”

"These are not problems, Rhodes. With the processing technology of Dawning City, they can completely mass-produce a reduced version of the purification device. Merlin patted the scholar's thin shoulder: "Sort out the relevant records and production materials, and then let Artemili send them to Dawning City." ”

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

Merlin thought for a moment and said in a deep voice, "Let's call it Yasuo." ”

Yasuo...... Hopefully? That's a fitting name. The scholar said softly.

In the language of the green capital, Yasuo means hope. The advent of Yasuo Crystal will completely change the whole world. This spar is not a natural product, but is made from several ores that are crushed, melted and then synthesized. In the end, if it is cut into a perfect hexahedron in the right way, it can be used as an energy source for the Netheres Shield.

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

In short, with the Yasuo Spade, at least the energy problem of the Netheres shield will be solved. It is conceivable that when this kind of purification device is no longer limited by energy, it can enter the factory assembly line for production. It won't be long before life on Earth can live on the surface under the protection of the Netheres Shield, instead of hiding in underground bases or other harsh environments.

Even the earth's environment has been improved as a result, ushering in a new era!

When he walked out of the lab, Merlin felt that the world was completely different today. But the Red Grand Duke didn't know that the crisis was approaching step by step. As Merlin strode to the temple to tell Ademili the good news, five hundred kilometers away from the Green Capital, a paw covered in light armor was pressing on the mossy lichen that covered the ice fields.

The soft lichen made the claw sink slightly, and one of the guards lowered his head, and after a flicker of his three pupils, he whispered behind him. Then only a black guard rushed past it, and from the sky, a black wave quietly poured into the dark green ground, continuing in the established direction. But the guards also didn't know that under their feet, the moss covering the entire tundra was not a natural plant, but a vigilant system specially set up by the green capital.

The moss was pressed, and their rhizomes soon began to quiver. Encrypted signals are transmitted through the rhizomes underground, and are quickly fed back to the intelligence room of the green capital. A special alarm immediately sounded in the intelligence room that only intruders would appear, causing Director Revan to jump on his ass.

"What's going on?" raven exclaimed.

"It seems that the watcher has spotted the intruder, and now the footage of the backhaul is being parsed. Okay, sir, please take a look. ”

A staff member taps the light key under his hand at great speed, and soon, the main screen of the wall appears one after another. Seeing these quietly and rapidly advancing biological weapons, Raven almost screamed, "Quick, get Lord Merlin." ”

Ten minutes later, both Merlin and Ademili appear in the intelligence room. Looking at the black biological weapons in the picture, Merlin's face was heavy. Ademilius looked at the Grand Duke and said in a deep voice, "Hamomis once said that once the mother awakens, the black wave will flood the earth. ”

"You think this is the creature legion of that thing?" Merlin asked rhetorically.

Ademili looked at the screen, "Look at them closely, Merlin. They are almost identical, and there is no communication during the entire process, indicating that they have received some kind of command. If these things aren't biological weapons, can you tell me what they are?"

"Well, damn it. Raven, do you know how many of them there are?" Merlin said loudly.

Director Raven himself threw himself in front of the workbench, waving his hands continuously, after a moment. He raised his head and said with an ugly face, "Based on the information fed back by the monitors, it is inferred that there are at least thirty thousand of them. ”

"Ladies and gentlemen, look at these. A staff member suddenly shouted.

The main screen changes again, this time with Crimson Guards flapping their wings and flying low. There was no doubt that these red guards were the elite of the biological legions, and when Raven reported the thousands, Merlin's breath was a little heavier.

"How long will it take for them to arrive?" Merlin asked.

"Less than 36 hours!"

"Time is of the essence. Merlin looked at Ademili and said, "It seems that you have to leave early, and I asked the people from the new energy development team to speed up." Once you've got all the information in order, you'll take it to Dawning City and tell Zero about the situation. Ademili, ten hours at most. At that point, you have to leave. ”

"What about you?"

Merlin looked at the screen and said, "Someone has to buy you time, if these guys catch up with you, our hopes...... No, the hope of the planet is gone. Remember, you want to leave as fast as you can. ”

Ademili sighed softly, but nodded.

Merlin then said to Raven, "Go and inform the other cities of the Federation and ask them to send troops into Stormkeep." If we're done, we'll need a second barrier to keep these black guys at bay. ”

On this day, the whole green was boiling. The army needed to be mobilized, the civilians began to move and retreat, and Merlin himself sat alone in the temple. He sat on the ground and looked at the throne that had once been high above Hammisis. Flame Planter lay across his knees, and Merlin sighed, "My lord, maybe this time, I won't be able to keep this city." ”

The wind blew into the temple, and it reverberated lowly, like the sigh of Hamomis.

In the green capital, civilians and soldiers are just as busy. The former packed his bags and prepared to leave the city where he was born and raised. The latter carry all kinds of ammunition out of the warehouse, or inspect the power mechs to make sure they don't have any surprises when they are fighting. There is still more than a day before the contact with the Black Army, and this time is neither long nor short, just enough for the green capital to deal with.

This was due to the green moss that covered most of the tundra, and if it weren't for them, it would have been too late by the time Midori discovered the Black Army.

The noise of the city continued from daytime to evening, and groups of civilians began to leave. Merlin drew an army of five hundred men to escort them, and Ademilius would follow. But before she could set off, she came to the temple. Taking a deep breath, she pushed the door of the main hall open. The moment the door opened, she even had the illusion that Hamelmis was still sitting on the throne of the Temple.

If Hamelmis had not departed, would it have been a different situation at this moment?

Merlin's majestic back caught Ademili's eyes, and in him, Ademili saw many things. The Red Grand Duke sensed her arrival, but he didn't even look back for a moment.

"I'm leaving. ”

"I know. ”

"Will we meet again? Ademili said softly.

A smile escaped from the corner of Merlin's mouth: "You know the answer, why do you bother to ask me." Let's go, Artemilie. Take ours, and the hope of the world, out of here. Whether it's Lord Hamermis or the Green Capital, we have all fulfilled the mission entrusted to us by the times. Even if it disappears, it is not a good thing. Adults have foreseen this for a long time, haven't they?"

"I see. Take care then, Merlin. Ademilius gave Merlin a deep look, as if to engrave his figure in her mind.

Another close friend is leaving, and a slight sentimentality crosses Ademili's heart. She turned and walked away, in the opposite direction to Merlin. One side is life, and the other side is death!

Gradually, the noise in the green capital quieted down. The civilians had left, and now only 5,000 soldiers remained in the Green City. At dusk the next day, all the soldiers received the order to assemble, and 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 Verdict, and stood up. Putting on the dark red armor components placed next to him one by one, when the armor was all put on, Merlin's eyes flashed sharply, and he strode out towards the square.

Seeing the Green Capital warriors standing like javelins in the square, Merlin shook his axe and said loudly: "I am very relieved to see that you have not flinched, the warriors of the Green Capital!"

"Your commander should have told you the specific situation, so I won't repeat it. I would say that this battle is going to be so hard that I don't even know how many people will survive. All I know is that we have to do everything we can, even at the cost of our lives, 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 by half a step! Tonight, we will fight to the death!"

"Fight to the death!"

"Fight to the death!"

The warriors of the Green Capital raised their weapons and let out a continuous roar.

The western light finally fell below ground level, and night fell. The reddish light of the sky fell like a veil on the tundra, casting a faint layer of blood on everything. In the basin on the surface of the Green Capital, a ring of metal defensive walls is the artillery fortress of the wind-operated cannon, which is connected by railroad rails, which allows the wind-operated cannon to move and concentrate fire as needed.

More than 200 Marauder power mechs have been moved to the ground, and the Green City Warriors are located in the cantonment barn, allowing them to quickly enter the surface to fight if needed. Merlin stood alone on the tundra in front of the fort, his tomahawk touching the ground, and the wind blowing the red cloak behind him, like an unquenchable fire of war in the night.

The wind was blowing from the front, accompanied by the night breeze and a slight tremor of the ground.

"It's coming. Merlin said softly.

Although in the vast night, the distant tundra was shrouded in a dim skylight, and nothing could be seen. However, in the intelligence room of the Green Capital, Director Raven was able to see a large number of guards approaching through the watchers. Raven immediately grabbed the communicator and shouted, "They're coming, they're coming!" and 10 minutes are still in the range of the cannon. ”

At his reminder, the turrets of the wind-moving guns began to move. The large pieces of iron gathered along the rails behind Merlin, the forts next to each other, and the muzzles of the guns were reoriented towards the far end of the tundra in the darkness of the night.

On the left and right, the power mechs walked out and came to Merlin's side, forming a steel defense line. More soldiers were in the cantonment barn, waiting for orders from their commanders.

Finally, in the far reaches of the night, something flickered. Merlin took a deep breath and roared, "Smash those bastards for me!"

"Wind cannon, fire!"

"Fire!"

Suddenly, the artillery fort behind Merlin roared incessantly. The muzzle of the wind-operated cannon was slightly adjusted upward, and after the air compressor accelerated the airflow, it pushed the physical live ammunition to burst out from the muzzle, and after passing through the parabola in mid-air in a projectile mode, one after another firelight fell from the sky and fell towards the tundra more than 2,000 meters away.

The first shell whistled down, and in the firelight, several guards could be seen raising their heads, and then everything was shrouded in the flames of the explosion. From a distance, the tundra thousands of kilometers away exploded, and the expanding flames continued to dissolve, forming a blazing fire cloud! In the fire cloud, a large number of guards who had been shot and fell, but more biological weapons passed through the fire curtain.

The black guards moved forward in the pattern of flywheels, and they let out a sharp whistling across the tundra, and the swirling bone spurs ploughed up the ice chips and moss of the tundra, and flew forward under the constant bombardment of the green capital artillery array. The Crimson Guardians flew into the sky, their wings vibrating, swept up to a height of more than ten meters, and then rushed towards the green capital. So in the night sky, a red cloud suddenly appeared.

"It's a flying unit, shoot down!

The cantonment warehouse opened, and a group of gunners from the green capital poured out, occupying the top of the defensive wall, raising weapons like gunpowder rifles of the old era, but blasting high-energy beams from the muzzles. In front of the artillery array, the power mecha also raised its arm, and the mecha pilot pressed the firing button hard, so the six-barreled cannon hanging on the mecha's arm also roared.

For a moment, countless beams of light swept up obliquely into the sky, along with the bright chains of fire shot out by the machine guns, and blasted into the red clouds that drifted from afar. The Crimson Guards immediately dispersed in formation, and they nimbly shuttled between the beam and the line of fire, but from time to time the Guardians were hit and fell from the air.

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

After the black guards on the ground advanced another kilometer, the infantry soldiers in the cantonment warehouse finally drove out. Each of these infantry soldiers carried a heavy sword with a thick back, and the captain of the guard, Balmore, was armed with a double sword. Baltimore came to Merlin's side, eyes fixed on the front. By the time the Black Guard had advanced another 500 meters, the pneumatic cannon had switched to flat-fire mode.

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

"It's our turn, do a good job, boys!" Balmo shouted at the infantry soldiers behind him.

Merlin pointed forward with a battle axe and shouted, "Mecha troops, face the battle!"

Immediately, the Marauders pressed down on their guns, ignoring the Crimson Guards in mid-air and instead concentrating their fire on the ground. The powerful cannon barrage was overwhelmed, and the powerful bullets slammed into the flywheels, immediately blasting huge wounds on their bodies. If the guards can't take a few bullets, they will be killed by Boom Fly. For a moment, the Defenders' forwards fell in large swaths, and only a few flywheels were able to cross the firenet.

The Baltimore heavy sword swung down with great force, and the roar of a foot warrior sounded behind him. Crowds poured past him and Merlin, slashing at the flywheel that crossed the firenet. Warriors work in groups of four, and with a single swing of their heavy swords, they can easily slash and tear apart the guards. The fire of the raiders and wind-activated cannons continued to hit the Black Legion, and under the strong fire of these weapons, only 12 out of 10 guards were able to cross the fire net.

This amount was quickly eaten by the infantry soldiers.

But whether it's Baltimore or Merlin, they are quite aware that the advantage of the green capital is only temporary. When the Marauders and Wind Cannons run out of ammunition and don't have enough firepower to block the enemy's advance, the tide will turn in an instant.

What's more, these black legions also have air support units, which are temporarily intercepted in the night sky at a distance of several hundred meters. But once it gets close, it will also pose a threat to the ground forces in the green capital.

Therefore, the temporary advantage of the green capital does not mean anything. As Merlin foresaw, this will not be an easy battle!

At this moment, a strange whistling suddenly sounded in the sky. But a ball of fireball swept down diagonally, smashing into the position of the infantry soldiers, and in the bright flames of the explosion, at least a dozen soldiers fell to the ground. The Crimson Guardian of the Sky has begun to threaten.
