Chen Xu turned his head to look at Yang Jinxia, ​​his eyes flashed slightly, and said, "I know, no matter what I do, you will support me."

"Um."

Yang Jinxia stretched out her other hand and touched his face, "You want to be a good person, I will do good things with you. You want to be a bad guy, I will accompany you to kill and set fire."

Chen Xu held her hand tightly, looked into her eyes, and did not speak for a long time.

...

"The loss report is out" Zheng She's words rang out next to her, "A total of 7,000 robots and 500 drones were lost. There are 652 signal relay stations."

This was a huge loss for the entire base. Chen Xu arranged two lines of defense, one was two thousand robots, and three kilometers away, there were five thousand robots, and there were more solid fortifications.

Unexpectedly, the mysterious weapon was so powerful that even five thousand robots a few kilometers away were destroyed.

With this, the robot lost nearly one-fifth.

There are still five hundred drones, losing one-third.

In comparison, more than 600 signal relay stations are nothing, and they can be completely repaired in one day.

However, at this time, Chen Xu no longer cared about the big losses.

…………

A few days later, the landing ship came back and brought back a large amount of nuclear fuel, which finally solved the problem of energy depletion.

The original mission of the landing ship was to explore. The original plan would have continuous reinforcements, so the amount of nuclear fuel was not large. Fortunately, there was sufficient fuel on the later supply ship.

Chen Xu has been expanding wildly over the past seven years, and his fuel consumption is very large, and he is almost at the bottom.

Now, with a constant stream of fuel, the stall can be spread out without any scruples.

This can be regarded as the second stage. Chen Xu’s plan is to create a controllable nuclear fusion power generation device. To do this, he must first fill the front-end technology one by one. Looking back, the number of technologies that need to be lit is simply daunting.

It's roughly estimated that it will take ten years.

The underground world may have been scared and did not send troops to the ground. Chen Xu did not take the initiative to attack the underground world, but this does not mean that he did nothing. He sent the clone out again and entered the underground world. The main mission still needs to be done.

Half a year later, the clone came back safely.

The forces in the underground world really did not dare to attack him.

This time, he learned the clones of the underground language and brought back a lot of information about the underground world. Later, major forces rushed to contact him. This time he even learned the writing of the underground world, which can be said to have gained a lot.

After retrieving the contents in the smart brain, Chen Xu sent the clone to the underground world again.

In this way, two years later, Chen Xu emptied the secrets mastered by major forces in the underground world. It was so simple that it was unbelievable.

According to the "Shrine", a thousand years ago, this planet, like the earth, lived on the ground. At that time, there were neither the clouds that wrapped the entire planet nor the strong radiation.

Until one day, the war broke out.

The cause of the war is still a mystery. I only know that suddenly, a major country threw a nuclear bomb at another person. In just one day, the nuclear war started, which caught people off guard.

And this is just the beginning, and the next is a war that lasts for a hundred years.

In this protracted war, in addition to nuclear weapons, there are also various newly developed super weapons, meteorological weapons, genetic weapons, etc., rushing to use them.

The damage to the environment by war was too serious, and it became uninhabitable, so countries began to dig holes at the same time. This is the origin of the underground world.

In the end, the small countries were almost dead, and only a few big countries were left to survive. In order to survive, and they could not continue, the war was declared over. At that time, all human beings had moved underground.

At the beginning, the underground of this continent was connected and had subway access. Until an unprecedented earthquake caused a large-scale collapse of the underground world, countless casualties, and at the same time, it also completely cut off traffic.

The area of ​​District 13 is not small enough to accommodate millions of people. It would not be impossible if we could work together to reopen the channel at that time.

Unfortunately, under the selfishness of some people, this option was abandoned. Gradually, it evolved into what it is now.

Chen Xu also obtained the map of the underground world entrance of the entire continent. The closest distance is 500 kilometers away, which is the entrance to the 12th District.

"The bones of these people are too soft."

Yang Jinxia couldn't help but sigh as she looked at the information. This was her fourth time entering a dream, and it was also the tenth year that Chen Xu had entered a dream.

"Even such secrets are revealed on their own initiative."

Chen Xu said, "If they have some backbone, they will not end up today. I have to say that this food manufacturing technology is quite interesting."

"If they hadn't spoken out on their own, the clone might not have found the entrance to the underground floor."

In the underground world, there is another floor below, where laboratories, manufacturing factories, and places to grow grain. Corresponding to the living area on the upper floor, the next floor below is the production area.

When entering the production area, you have to pass through several entrances, and these entrances are occupied by major forces and outsiders are not allowed to enter. The task of the clone is to collect intelligence and not to cause trouble on its own initiative, so as not to delay the task.

As a result, several forces in the underground world frightened themselves and actually took the initiative to explain.

The factories and laboratories on the underground floor are basically abandoned, and only the planting areas are still operating.

The so-called food is the most important thing for people. They can rule the Thirteenth District because they control the planting area and the food.

After Chen Xu learned that there was a production area underground, he sent a robot to search. The people from those forces seemed to be scared and didn't even dare to stop them.

In this way, Chen Xu obtained a large amount of technical information on this planet. A large part of it has been lost. After all, it is too old, and many computers have been scrapped and even the storage devices have been completely damaged.

Of course, these things are just icing on the cake. He couldn't even learn the techniques on the spacecraft, let alone the technical materials of the underground world, so he could only use them as a reference.

Chen Xu said, "According to our current progress, we will be able to expand the base to the entrance of District 12 in another half a year. I don't know what the situation is there."
