Chen Xu saw her serious face and knew she was serious at the moment, so he let go of her hand and followed her to the room where the life support chamber was placed.

Luo Xiyun lay down in her life support chamber, closed her eyes, and went offline.

Chen Xu felt a little empty in his heart. From childhood to adulthood, what he feared most was separation. In the past seven years, whether it was Luo Xiyun, Yang Jinxia, ​​or Bai Jinxuan, every time they went offline, he would feel uncomfortable for several days.

This emotion became even more obvious when he was the only one left in the base.

It wasn't until a week later when Yang Jinxia came online that the feeling of loneliness was alleviated.

"He looks good with a beard, too."

Yang Jinxia came online two days earlier than Chen Xu expected and appeared directly in the living room, which scared him.

"You're here." When Chen Xu saw that it was her, he put down what he was holding and hugged her in his arms. He hugged her tightly, as if he wanted to rub her into his body.

…………

Inside the control center, Chen Xu, who had just shaved his beard, looked much more energetic. He said to Yang Jinxia, ​​"The development of the base has reached a bottleneck. We are running out of energy."

He was introducing the current situation of the base. Among the three women, only Yang Jinxia cared about the base's affairs. Luo Xiyun and Bai Jinxuan rarely asked about it.

These things can only be discussed with her.

Yang Jinxia stood in front of the screen, flipping through the information, and asked, "How do you plan to solve the energy problem?"

Chen Xu said, "In the early stage, we usually rely on solar energy. However, this planet is special. The entire planet is covered by thick clouds, which does not meet the conditions for solar power generation. At present, we can only consider hydropower. Building a few power stations on the river over there can also alleviate some of the problems."

Yang Jinxia said casually, "That river doesn't seem to have any particularly large drop in elevation, so the power generation efficiency isn't very high."

"I have explored all the areas we can explore so far. There are no coal mines or mines containing radioactive elements. Other methods of power generation are useless."

Yang Jinxia looked away from the screen and asked him, "Is there no other way?"

"Yes." Chen Xu pointed upwards and said, "The satellites above have abundant nuclear fusion fuel. If we mine all of it, we will have enough to build a base like this on the entire planet."

Yang Jinxia asked curiously, "Where did this information come from?"

Chen Xu said, "Last time, a satellite fell down and I found relevant information on it."

"oh."

"Now, we have to find a way to get on the satellite and mine the fuel."

"Then we can only use another landing ship."

"I thought so too. Two years ago, we started training cyborgs that can fly spaceships. It will take a few months to mature."

Seeing that he already had a solution, Yang Jinxia nodded. What restricted the development of the base was energy. As long as the energy problem could be solved, everything else would not be a problem.

Chen Xu added, "I plan to take advantage of these few months to get rid of those black birds."

When the landing ship landed, it was the attack of those blackbirds that killed the rest of the exploration team. Now, it is time to avenge them.

Chen Xu had also conducted research on these black birds. He had killed quite a few of them and through studying the corpses, he had gained some understanding of the habits of these creatures.

Their hearing is very sensitive. When the sound is too loud, they will become enraged and go into a rampage state, frantically attacking the object that made the sound.

He planned to solve this problem in advance.

Since they are sensitive to sound, it is easy. Chen Xu chose a place, placed a high-power speaker, and deployed a large number of weapons around it. When the black birds were lured over, they would be killed.

Chen Xu did not go to the scene, but stayed at the control center, watching the video and seeing that the plan was going smoothly, he stopped paying attention. This was a completely one-sided massacre.

The number of black birds was beyond his imagination. He killed them for nearly a month before no new black birds appeared.

After eliminating the hidden danger of the black bird, all we have to do is wait for the cyborg to mature.

Everything went very smoothly. Chen Xu trained a top-level bio-human, so piloting a spaceship was no problem. The ship that took off this time was the one Yang Jinxia and her group were on, with three top-level bio-humans and a group of robots.

…………

"The underground human world is interesting."

In the living room, Yang Jinxia sat on the sofa, looking through the information. Ever since she knew about the existence of the underground world, she has shown great interest in it.

"To be able to build such a huge base underground, the level of technology is extremely high. I didn't expect that it would degenerate into what it is now."

Chen Xu said, "This is a negative example, proving what happens when a civilization loses its vitality."

As to why it lost its vitality, it is obvious.

At this time, Chen Xu saw the red lights in front of him lit up, and two lights lit up at the same time, which meant that there was a very urgent incident.

Yang Jinxia noticed his gaze, turned around and said, "Let's go and see what happened."

The two came to the control center, and Zheng She, who was on duty, said, "The underground human army has appeared."

Chen Xu was not too surprised to hear the news. When the clone came back some time ago, he had already expected such a day to come, but the underground humans came later than he expected.

Seven years had passed, which was about one tenth of his lifespan. The base had reached the limit of its current energy.

When the fuel on the satellite is transported back, the base's strength will once again usher in a period of rapid growth. At that time, appearing again will be like delivering food.

Right now, this point is just right.

In the video, there are underground humans appearing, wearing silver protective suits that look much lighter than the ones in the base.

In addition, large vehicles were continuously driving out of the cave.

The most conspicuous among them was a group of people wearing parasitic armor, numbering more than a hundred. The most obvious feature was that they were not wearing protective clothing.

The last vehicle to come out was an oversized car with a long carriage at the back. No one knew what was inside.

When the largest car stopped, the front of the car suddenly lit up, and then the video went black.

PS: I am too sleepy and can’t hold on any longer. I will go to sleep first. Please give me some monthly votes.
