"General control, the report has been uploaded, you can check it." Staff reported.

Yang Ping raised his wrist, and the mobile phone intelligence automatically projected the content of the report for him, which confirmed that the Sky Wolf was depleting oxygen and filling carbon dioxide, and the way it was used was to burn, which was equivalent to adding five furnaces to the inside of the Sky Dome.

However, the overall consumption is not large, except that the temperature inside the sky dome will rise to a hotter level, and the oxygen can still support the consumption of one day and two hours.

"If we keep the central gas circulator running, will we be able to use oxygen?" Yang Ping asked.

"Yes, if the werewolves can't increase the burning rate, it's fine."

"Then keep the machine running, as for the werewolves, their landing module is not a carbon stove, I don't believe they can increase their combustion any more."

"Is there a plan?" Owen, who had been sitting on the sidelines, said that he did not intervene in technical matters, and he was a good hand when it came to action.

"Plan A, Owen, you try to see if you can solve a sphere and restore the energy line, I will take people to the top of the sky dome, plan B, I will take people to replace the battery, plan C, immediately build a new line, three plans at the same time, the first two plans buy time for plan C, after all, even if the line is restored, it will inevitably be destroyed by the werewolves again."

"No problem, I don't believe I can't pry that wrecking ball." Owen patted his chest and reassured.

"No, the sphere has been fused with the sky, the twisted part is likely to be damaged, it is all up to the sphere to block it so that there is no gas loss, I need you to take the sphere, and then take a detour or reconnect the line through the sphere, I will assign a maintenance worker to assist you."

"Okay, I'll do my best to keep the communication going."

"Yes, I have notified the maintenance worker, he will be there immediately, in addition, turn on the maintenance mode, close the room, and use it as oxygen storage."

The maintenance mode is a unique feature of colonial buildings, and is designed to take into account the loss of oxygen if the sky dome is damaged, so a sealing device is installed at the gas entrance and exit of each building.

People can take refuge in the house and use the oxygen in the room to wait for the repair to be completed, so as to avoid the long repair time and the rapid loss of oxygen causing casualties.

"The repair mode is on, and the condition is normal."

"Okay, so ...... you guys"

"Ah~~~!"

A scream echoed in the general control room, causing Yang Ping to almost bite his tongue and ...... What's wrong again?!

I saw that the staff of the surveillance drone was pale, a lot of cold sweat broke out behind his back, and the screen in front of him was dark.

My colleague hurriedly handed me a glass of water and asked him to quickly recover from the shock.

"What happened?" Yang Ping frowned, and he didn't reassure people, what tricks does the wolf people have that they can't come together, the soldiers will block, the water will come to the earth, and the grinding and chirping look like.

The previous replay was projected on the big screen, and the frightened staff members decisively turned their heads away, not ready to be stimulated again.

I saw that in the round hole in front of the drone, there was an extremely ugly four-like, which was the head of a robot, but the aesthetic of the wepreus is really different from that of humans, and the person with a bad heart was basically cured at a glance.

Staring at it for a while, the strong psychological acceptance can finally bear it, but it's a little disgusting, just looking at this face can be ugly to death, and it has its own lethality.

The robot destroyed the drone with one palm, causing the picture to be lost, and the hapless staff member was caught off guard and screamed as if he had watched a thriller movie.

The screen switches, and a hundred robots are lowered from under each sphere and fall into the colony.

The Martian Guards guarding below immediately opened fire, strafing the robots, and several of them exploded in the air.

The bullets at the firing site of the gunpowder weapon have little effect on the robot's outer armor, and only if you are lucky enough to hit the back of the robot's neck and eyes and other fragile and unarmored parts can you paralyze the opponent.

When everyone found out about this, it was too late to reload under the command of the commander, and the ugly robots fell to the ground, they were also equipped with gunpowder weapons, but they were more ferocious in vitality, rapid-fire machine guns automatically locked onto humans, and people without cover protection were shot.

Reacting to this, the Martian Defenders jumped into cover and began to return fire, and the men without guns rushed out to rescue their seriously wounded and undead companions.

However, the rapid-fire machine guns did not give humans any respite, and those who rescued the wounded not only failed to save their comrades, but also took their own lives.

For a while, blood flowed in the battle zone between humans and Sirius robots, and dozens of people were killed and injured in an instant, and each war zone was the same.

The drone filmed this scene from above, making everyone's faces in the control room hot and painful, and the wepus were not only ready to consume humans from oxygen, but also to kill them from firepower.

In just a dozen seconds, the war zone changed again, and more than a dozen Sirius robots took off some kind of canistry-like object on their backs and threw it at the human bunker.

A violent burst of light rose up, and the vibration of the explosion was felt throughout the sky.

After the explosion, the human defense line turned into a puddle of ruins, with heavy casualties, and the houses on both sides also collapsed, enclosing the landing site of the Sirius robot, and turning to form the defense line of the Sirius.

The sphere throws a box again, which is caught by a robot underneath, and is opened to assemble into a makeshift repair site, where the less severely damaged Sirius robots can be repaired, and the more completely destroyed ones become parts to repair other robots.

The intact robots were pushed outward in several queues, and the surviving humans in the ruins got up, grabbed steel bars and tools, or cluster grenades, and launched a melee attack on the Sirius robots, and the results were naturally not good.

In less than ten minutes, the casualties of five hundred humans in five war zones were replaced by less than thirty robots, half of which were destroyed in the air, and after landing, the flexible and powerful Sirius robots were even more difficult to kill, and they knew how to protect the vital points.

"I remember that there is a gas circulation system in the ecological greenhouse, right?" Yang Ping said.

"Yes, the power of that unit is not large, and the energy line used is also independent."

"Okay, change the system, Owen, you assign the defense forces to fortify around these five war zones, be sure to withstand the attack, and the rest of the people abandon the defense line and stay in the house or ecological greenhouse without receiving the order to take position, so that the defense forces in the battle have enough oxygen to breathe, and at the same time buy time for the laying of the new line, everyone should act immediately!"

"Yes, Master Master!"

The people in the general control room were busy, and when they got into their respective positions, Yang Ping took Owen's hand and stuffed his own gun into Owen's hand.

"Your mission is more dangerous, you must come back alive, the sky needs you!"

"Thank you, Brother Yang, isn't it just a ball, nothing to be afraid of!"

That's right, isn't it just a ball, if you can't kick it away, you have to smash it!
