"The caving is in place, and the intended penetration position is about fifty meters outside the shelter." Lu Jian waved his arm excitedly, "In order to prevent the drill from destroying the power equipment and causing unnecessary accidents, you must turn off the artificial gravity equipment in the power compartment in advance. ”

Despite sufficient design demonstrations, how is it possible that more than 200 kilometers of caving can be accurate without the slightest error? If the drill bit is drilled directly into the gravity equipment, it is likely to cause the gravity equipment to malfunction, if the artificial gravity disappears directly, it is okay, I am afraid that the gravity equipment will suddenly cause an abnormal increase in gravity when the equipment is damaged, and then all the seriously injured people will not want to survive.

"Understood, how much time do I have left?"

Lu Jian raised his eyes and glanced at the time: "The drill bit will enter the sixteenth floor in ten minutes, but the Liuzhou will wait for your signal to drill through the formation...... Hurry up. ”

"Yes!" Ye Fei strode out of the shelter, grabbed his rifle and roared, "All assemble - put on your armor, quick!" Fast! Fast! ”

The scattered rest commandos quickly put on their battle armor and rushed out of the dormitory to the lobby, and the hallways were immediately filled with running figures and heavy footsteps.

The soldiers quickly lined up in front of Ye Fei, and the three captains of the whole team sounded the password, and each reported the assembly situation to Ye Fei and returned to the team.

Ye Fei's eyes were blazing: "Brothers, the Liuzhou will soon be able to open up the asteroid, and the health officers of each detachment will come out and go to the sea, under your command, and immediately prepare to transfer the wounded." ”

"Yes!"

"Black Bear, take your people and seize the passage between the sixteenth and fifteenth floors as fast as possible. Before the order to retreat is given, you must nail me there firmly, not a single step back! ”

"Yes!"

"Saber, completely sweep the sixteenth floor, be sure to remove all the outer skeletons, and leave no one behind."

"Yes!"

"Monkey, follow me with your guys and snatch the gravity equipment bay down, be careful, before turning off the gravity equipment. No one is allowed to shoot at gravity equipment. ”

"Yes!"

"Are the tasks clear?"

"Clear!"

"Good!" Ye Fei strode in front of the queue with a gun in one hand. "Win or break here, monkey, take your man, line up behind me. Get ready for battle! ”

Shortly after retreating into the shelter. A dense tapping sound could be heard on the bulkhead near the hallway of the base. For a whole day and a night, I didn't stop for a second, and I don't know how many exoskeletons gathered outside the road.

"Yes!" The monkey strode out of the queue. "Three teams, turn to the right, run to walk...... The first row is lying down, the second row is crouching, ready to shoot—"

The sound of pulling the bolt and loading the bullet was extremely neat, and dozens of rifles were all adjusted to a burst of fire to aim at the gate.

Don't look at the fact that there are less than fifty people left in the three teams that have drawn out the hygienists, but the area of the gate of the shelter is limited, so it is impossible for such people to spread out, even if the three-stage firing queue is discharged, the length of the queue is still much wider than the gate, and it must be gathered into an arc to exert the firepower of all the team members.

"Open the door—"

"Open the door!" Xiang Hai personally pressed the switch of the gate, and the heavy iron door of the opposite door slowly parted under the drive of the motor.

The door opened only a thin slit less than a finger's width, and a sharp purple bone shield blade suddenly plunged into the crack in the door. Ye Fei picked up his rifle against the crack of the door and pulled the trigger, the crisp sound of gunfire echoed in the lobby, and the dense bullets hit the purple bone man outside the door, directly turning it into a honeycomb.

At this time, the gate had been opened more than a palm's width, Ye Ye quickly evacuated the gate, and the monkey roared: "Free fire-"

Fierce gunfire rang out suddenly, and a series of explosions were like the waves of the sea, and it was impossible to tell the number.

The Outer Skeletons as they prepared to storm the shelter were met head-on, a rain of bullets piercing through their bone armor, stirring their internal organs, and tearing apart their bodies at the very end.

The stormy warheads pierced the Outer Skeleton and then all hit the side arms of the corridor opposite the gate, and the surface of the bulkhead made of aluminum foam was riddled with holes in the blink of an eye.

The outer skeleton man who wandered outside the shelter for three days was like a bandit army besieging the city for three years, seeing that they had entered the city, and there were a lot of silver women, how could they give in a little?

The two sides fought fiercely around the gate of the shelter, and the nine machine gunners of the three teams made a great achievement, and the nine Gatlings swung in the door, and the gate, which was only a few meters wide, could be defended even if it was a position of several hundred meters, and no matter how many people came from the outer bones, they all had to be filled into the pit.

The reason why Ye Fei has the confidence to fight to the death is because there are enough ammunition stored in the shelter, and no matter how fierce the battle is, it is enough.

The number of casualties of the Outer Bone Man skyrocketed, and after holding out for more than ten minutes, the Outer Bone Man finally couldn't hold on anymore and reluctantly stopped the death charge.

"Grenades—" The prepared black bear roared, and the three-stage firing queue of the three major teams quickly retreated, and more than a dozen grenades were thrown out of the gate, and all the corpses of the outer skeletons piled up outside the door exploded with a bang.

"A big team, follow me!" The black bear rushed out of the vault first, and Gatling's bullet swept through the hallway like a long whip of flame, catching the evacuated Exoskeleton by surprise.

"Second Brigade, let's go!" Saber followed, leading the warriors to protect the rear of the black bear, and the two brigades advanced to both sides of the corridor at the same time, constantly compressing the space for the movement of the outer skeleton with the strongest firepower.

"Three teams, forward!" The monkey was the last to break out, and the hallway had been cleared, but the road to the equipment bay still needed to be cleaned up by himself.

Ye Fei strode out of the shelter: "To the sea!" ”

"Here!" The answer was immediately heard on the radio.

"Close the gates and let me know when you're ready to evacuate."

"Yes!"

The three teams rushed to the goal, and Ye Fei rushed to the equipment cabin with the three teams.

I don't know if all the outer skeleton people of the road are concentrated near the refuge, after eliminating the first wave of enemies, Ye Fei's group of people did not encounter large-scale resistance until they arrived at the equipment cabin, only to encounter a large-scale enemy, after five minutes of fighting to eliminate this enemy army, the soldiers suddenly found that the equipment cabin had actually become the base camp of the outer skeleton people!

The outer skeleton people are all diehards, and they all resist to the end. After retreating into the equipment cabin, he refused to come out again, but Ye Fei was afraid of hurting the gravity equipment, so he didn't dare to attack at all, and the two sides fell into a stalemate that no one expected.

"One-one-one, Black Bear reports, our army has occupied the exit."

"Okay, you must hold it!" Ye Fei advised again.

"No. 1, No. 1, Saber report, the sixteenth floor has been cleared, and the fish that have slipped through the net are being searched." Not for a while. The saber also fulfilled the intended goal.

"What a net. The bony mongrels are fucking in the equipment bay! Ye Fei didn't fight when he mentioned this.

"Huh? What the! Saber was startled, and cautiously suggested, "Do you need us to come to help?" ”

"What is the support, there are enough people here. If you weren't afraid of breaking the equipment. I had already rushed in. Ye Fei gritted his teeth and grinded his back molars with a gurgling sound.

The saber looked up at this time: "Boss." My current position is outside the power cabin ......"

Ye Fei's brain was like a bolt of lightning: "You just stay there, ready to shut down the reactor at any time." "Why didn't I think about it, since the gravity equipment cabin can't get in. Why not cut off the power of artificial gravity equipment?

"Understood!" The saber roared, rushed into the power cabin with a squadron, and carefully checked it until he was sure that there was no outer bone man to hide, and then asked a few soldiers to guard the hatch and wait for Ye Fei's order.

"Monkey, block the gravity equipment hatch and wait for my orders."

"Yes!" The monkey immediately arranged for the fighters to block the corridor.

If so many Outer Bone People were all scattered all over the sixteenth floor, it would be enough for the saber to be busy for a while, and now that they take the initiative to gather here, it would save a lot of effort.

As soon as Ye Fei turned around, his gaze seemed to be able to look in the direction of the shelter through the layers of bulkheads.

Now it's time to see when the sea will be ready.

Transporting a wounded person in standard gravity conditions is easy, but transporting a seriously injured person in low gravity or weightlessness requires adequate preparation.

The seriously injured have no way to wear pressure suits at all, so they can only be transported into a barrel-shaped pressure support cabin, and the lightly injured should also be distinguished according to the situation.

Regardless of the battleship or the base, in order to prevent the soldiers from suddenly losing pressure when they are resting, they usually use the life-support cabin as a bed to sleep, and once the pressure is lost, the life-support cabin cover will be immediately closed to ensure the safety of the fighters, so there is no shortage of life-support cabins in the base, otherwise it will be difficult for everyone just how to transport the wounded.

Time passed minute by minute, and Ye Fei waited anxiously, but he would rather endure it himself than urge it.

The preparation for transporting the wounded is a meticulous job, the wounded must be properly placed in the life-support cabin, and the external medical equipment, such as body monitors, infusion sets, etc., must be placed.

After waiting for more than an hour, Ye Fei finally waited for Xiang Hai's communication request.

"I'm Ye Fei, please speak."

"Regiment commander, all the wounded are ready to be transferred, please instruct!"

"Good!" A big stone in Ye Fei's heart finally fell to the ground, "Contact the fleet immediately, inform the Liuzhou to drill through the base, remember, make it clear, after asking the Liuzhou to drill through the base, don't turn off the drill bit for the time being, when to wait for my notice, when to stop." ”

"Yes!" Xiang Hai agreed, and his heart was full of doubts, what did he want to do if the drill bit was not closed?

"This is where it begins." Ye Fei took a deep breath, "All pay attention, fix yourself, prepare for weightlessness and lighting, saber, and turn off the reactor." ”

He had never commanded such a battle, and on the one hand, he arranged his own crew, and on the other hand, he had to contact the fleet by going to the sea and turn several turns to command the Liuzhou.

"Yes, the reactor is off!" The saber slammed into the panic button to shut down the reactor, and the roaring reactor gradually stopped, and then the gravity under the soldiers' feet instantly weakened, leaving only the pitiful gravity of the asteroid itself; After a few seconds, all of the original illumination on the sixteenth floor disappeared, replaced by an emergency light source whose luminosity was weakened many times.

The core device of a fusion reactor is to bombard the reaction atoms with a high-energy laser to produce a fusion reaction, which is clean and clean, unlike a fission reactor that must go through a series of control measures to achieve shutdown.

All the members of the three teams waiting outside the gravity equipment cabin stood still, and the bright beams of the tactical lights illuminated the entire corridor as bright as day.

The commandos had been prepared for a long time. The sudden drop in gravity didn't cause any undesirable consequences, but not the unprepared Exoskeletons, who were thrown into a mess by the sudden change in gravity.

Originally, this was a good time to assault, but I don't know what kind of medicine was sold in Ye Fei's gourd, so he resolutely rejected the monkey's proposal to rush into the equipment cabin.

The wait in the darkness seemed to be incomparably long, and the warriors suddenly felt as if they had heard something, and the sound was getting louder and louder, and suddenly there was a bang in the equipment cabin, and the air quickly drained like a sudden storm that swept through the sixteenth floor.

At the same time, a bright laser beam instantly penetrates the bulkhead of the equipment. Criss-cross beams swirl and wreak havoc. Cutting the bulkhead to pieces, the already chaotic Exoskeleton Men exploded the nest like a flock of frightened sheep, and all the Exoskeletons who failed to hold themselves firmly in place were blown towards the laser drill bit by the wind. A very small number of exoskeletons who held their bodies in place rushed out of the equipment compartment in a panic.

Shattered walls and skeletal corpses flew towards the drill bit. Wall fragments and skeletons are like being poured into a blender. It is cut into finer pieces by the laser of the drill bit.

The soldiers guarding the sides of the corridor gave the escaped exoskeleton a happy shot with a mess, and seeing the rapidly rotating drill bits and flashing beams in the equipment cabin, the monkey lying next to Ye Fei suddenly realized: "Boss." Yours is the real thing. "No wonder Ye Fei asked everyone to lie on the ground just now, feeling awkward and lying down, no matter what happens, they are absolutely not allowed to get up, not even turning over.

If it weren't for that, the soldiers would have to let the wind sweep into the equipment bay and cause a tragedy.

"It's okay, it's nothing." Ye Fei smiled slightly.

The beam intensity of the laser drill level is not much worse than the laser cannon of the battleship, but because the frequency relationship spreads and weakens relatively quickly, the beam cannot reach far.

But this is far from the weapon-grade laser, the equipment cabin is so small, it can't affect the strength of the laser at all, and the next step is to give the outer skeleton people gathered in the equipment cabin a cauldron.

The lucky few who escaped the laser cutting could not escape the resistance of the foreign warriors.

It wasn't until there were no more external skeletons jumping that Ye Fei contacted Xiang Hai unhurriedly: "Okay, notify the fleet, you can turn off the drill." Saber, withdraw to protect the unobstructed passage from the shelter to the equipment compartment, and don't let the out-of-the-net out-of-the-net escape. ”

"Yes!" The two spoke in unison.

After waiting for another thirty seconds, the bright laser on the drill bit gradually faded and finally disappeared, and then the drill bit stumbled into the hole and disappeared.

If in space, the laser on the drill bit cannot be seen by the naked eye, and the drill bit is bright when it first penetrates the ground, because the equipment compartment is not only filled with air, but also filled with the blood that evaporates when the outer skeleton man dies.

However, with the gradual loss of air, the brightness of the laser on the drill bit is getting worse and worse, not because the power is reduced, but because the air loss takes away the gases and floating dust that produce the Tyndall phenomenon.

Ye Fei got up in a hurry: "Okay, get up, monkey, leave a few people to guard, and the rest of the people will help transport the wounded at the refuge." ”

The door of the shelter opened again, and the advantage of low gravity was that the survival pod for the wounded was incredibly light, and even ordinary warship soldiers without power armor could easily carry the pod alone. A team of more than 100 people was like a team of ants, carrying a life-support cabin larger than a body to the equipment cabin, and the lightly wounded were much simpler, just fly over.

Battleship soldiers are often active in the vacuum environment outside the cabin, and their rigid pressure suits can also be connected to external flight devices.

Xiang Hai's battle armor was broken, and at this time, he had to change into a hard pressure suit, and flew to Ye Fei's side and slowly lowered: "Regiment Commander, what about the remains of the martyrs?" ”

"Take away as much as you can and what you can't...... Bring one of the things they usually use, at least to give it to the relatives of the martyrs. Remember to mark it and don't mess it up. Ye Fei said gloomily.

In addition to the remains in the shelter, there were about six hundred bodies scattered all over the base, Ye Fei was impossible, and he had no time to collect the remains of the martyrs, he had to take the living out of the city first.

"Yes!" Xiang Hai whispered back, saluted, and flew away, retrieving the more than twenty uninjured battleship soldiers and handing over the task.

The evacuation work was orderly, all the bodies of the martyrs were transported, it was easier to collect the relics, each person's belongings had their own name on them, and they could be stuffed into the survival cabin at random, and it would not take a few survival cabins to transport all the relics of more than 600 people.

Everything was ready, Ye Fei left the shelter last, returned to the equipment cabin, looked at the messy life-support cabin and the wounded, and said: "Monkey, send a detachment to take the lead, the others, the commandos take the life-support cabin, and the lightly wounded bring the remains of the martyrs, and go!" ”

One of the fighters of the detachment was picked out by the monkeys, each holding a survival pod, and one by one they jumped headfirst down into the bottomless burrow.

The armor on their bodies can maximize the impact of the rubble in the hole and protect the soldiers who follow them.

The others then jumped in one by one according to the distance, until only Ye Fei was left.

"Black bear, how's it going?"

"No problem, the passage is sealed for me, and even if the outer bone mongrel wants to get in, it will take several hours."

"Just know that you're okay, withdraw it, don't forget to leave some surprises for the outer bone mongrel." Ye Fei said.

"Don't worry, I understand."

"Alright, I'll go first." Ye Fei jumped lightly and got into the hole like diving.

It was pitch black in the burrow, and he had to turn on the tactical lights.

The air in the base is all gone, the vertical hole is in a vacuum, there is no resistance at all, there is no need to fly in the first half, the gravity of the asteroid will pull the falling person to land all the time, due to inertia, the speed will only gradually and slowly weaken after passing through the center of mass, and it will not suddenly lose all the speed and stop at the center of mass of the asteroid can not go up or down.
