Nagku entered the interior of the colony, turned right and descended the stairs, and Frost came to a fork in the road. Bright lights illuminated the passages in front of and behind, and the enemies hiding behind the obstacles would be exposed by the slightest movements, and the cold concrete walls left no traces of time, and he could not guess how old the stronghold of this private armed group was.

This base is deep into the mountain, like a bomb shelter, unexpectedly large. The sheer size of the space made it easier for Frost to move, and despite the enemy's sheer numerical superiority, they were far less familiar with the colony than the data burned on the hard drive. With the assistance and guidance of Aixia, Frost quickly broke through the enemy's encirclement and interception, and at the same time used up tactical items such as smoke grenades and flashbangs.

When an enemy was confirmed dead and died in the control room, Frost had Axia open the two rail fence gates. There was almost nothing behind the fence door, and the doors of the four cells merged with the gray walls, as if after that there was another space, and the cells would be the end, a dead end.

"Room four. As soon as Axia finished speaking, Frost heard the sound of unlocking. He walked over and pushed open the door to cell four.

There was nothing in it, nothing but four white walls. The silver-haired girl was sitting against the wall opposite him, her arms folded around her knees, and when she heard the door open, she raised her head and looked at him indifferently with a pair of amber eyes. Wendy saw that it was Frost and struggled to stand up, but her legs were weak and she almost fell, but she was able to stand on her own.

"So the gunshot was caused by the chief?" Wendy said lightly, "I don't know what reason you have to come to the rescue, but I should still thank you." ”

Frost was silent, just looking at her.

"Don't you say something? I don't know the current situation and can't act effectively, so I suggest you give orders. ”

"Time is of the essence, Wendy," said Exia, "and the order will be delivered by me, the guide. ”

"Understood. ”

"Before that, I want to confirm your physical condition and whether you are fit to fight. ”

"Yes," Wendy said nonchalantly, "Based on the judgment that there is no escape, a hunger strike has been adopted in the past few days, intending to self-destruct before the experts of the Southern Alliance's relic biotechnology arrive, in case of a potential intelligence leak." But don't worry, as an artificial ligand, the current state of the body can still fight to a certain extent. ”

"I know, when I can't hold on, I have to report in time. ”

"Understood. ”

Frost waited quietly for them to finish, then unloaded the sniper rifle from behind his back and handed it to Wendy, the delicate work that might be more appropriate for him to leave to the artificial ligands than to himself.

"The goal now is to support Master Chief Unakin, so please follow the waypoint in the head-up display. ”

The two fought their way back, bypassing the enemy's sight from a workshop full of jars and machines, and using an elevator that was carrying an unknown object to the upper floor, which was divided into two rooms, each with just enough room for one person. After they went up, they walked out of the room and ran into a squad of the Southern Union and exchanged fire with the enemy again.

On the other side, Master Chief Unakin seemed to have arrived at the control room of the electron cannon, and Frost heard the sound of Exia connecting to the device, which was probably the control terminal of the electron cannon.

"We were too late. Axia said.

"What's going on?"

"The enemy has already started the launch program, and once the program is activated, it cannot be aborted, after all, a certain amount of energy has been accumulated, and it can only be released. ”

"What about the target of the Positive Electron Cannon?" asked Yunakin.

"The fleet at sea. ”

"Can't I change the target of the lock?"

"The locking was done on another terminal, and as you can see, it was breached before you broke down the door. ”

"Really...... In the end, it was a step too late. ”

It sounds like the situation is not good, and the end of the electron cannon fire may be irreparable.

"We can't stop the firing of the positive electron cannon, but there is another option. Axia said.

"What is it?"

"How about having the pyroelectric cannon 'fire at itself?'" the AI said with a laugh.

"What do you mean?"

"I looked at the construction of the electron cannon and found that there was an engineering terminal near the top, which was left over from the construction process to separate the parts when the power was on. The internal parts of the anodeon cannon are each separated, not fixed to each other, and the terminal can be used to reverse the launcher and the accumulator, so that the accumulated positive electron flow collides with the positive electron flow generated by the converter......"

"It's going to blow itself up," Mr. Yunakin said, "and what about the scale of the explosion?"

"It involves the whole of the Upper Town and half of the Lower Town, and only the waterfront area is spared. ”

"That's it. Unakin, who learned the result, only hesitated for half a second before making a decision. If they succeed, it will undoubtedly be a death sentence for countless soldiers.

Their pathpoint immediately changed, leaving the deep base, and they found themselves in a huge cavern, where large and small cables were laid on the floor, and after passing through several transformers, the number of wires became smaller, but overall, at least Frost had never seen a power supply of this scale.

"The power grid is already out of power, climb up the yang electron cannon along the circuit, and I will power it again after reversing the launcher. ”

Frost understood what that meant, and he jumped from above and landed on a cable longer in diameter than his height, the exoskeleton that mitigated the impact on landing, allowing him to run right away.

He looked at the entrance of the cave, the outline in the sunlight was part of the Yang Electron Cannon, and in addition to that, there were some surging shadows, and it was only when he entered the cave that he could clearly see that it was the troops of the Southern Alliance.

"Wendy, cover Frost!" a brief command came out of the communicator, and gunshots rang out from both the left and right rear.

Frost ran forward as best he could, bullets flying in front of and behind him, and he didn't look sideways. He could only move forward, without hesitation, crossing the dividing line between light and shadow, climbing the gun mount, and the ladder of the Yang Electron Cannon was in front of him.

He looked up with wide eyes, the sunlight stinging his eyes, and he kept his eyes on his target as closely as he could, reaching out his left hand towards the sky, and his hook flew into a white glow. Once the rope was tightened, Frost drove the exoskeleton's thrusters to the top.

The gunfire continued all around, and the wind in the cold wind above became much stronger, and the pitch-black metal surface reflected its own appearance. Frost crawled forward step by step, the cold and smooth shell was very difficult to navigate, but fortunately it was not a long road, he quickly climbed to the side of the electron cannon, uncovered the protective plate of the terminal, and connected the wiring to the corresponding port.

"Ready, powered-up, countdown to three seconds. "If you don't want to be electrocuted, jump off." ”

Aren't they all dead, Frost thought, and there's no way they're going to escape such a massive explosion.

Still, he jumped.

Overhead, the sound of electric currents stirring, and electric flashes illuminated the outer circle of his vision. Everywhere his eyes could see was quickly filled with a burst of white light.
