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

"Hmm."

Yang Jinxia stretched out his other hand and touched his face, "You want to be a good person, and I will do good deeds with you." You want to be a villain, I'll accompany you to kill people and set fires. ”

Chen Xu held her hand tightly, looked into her eyes, and didn't speak for a long time.

……

"The damage report is out-" Zheng She's words sounded beside him, "a total of seven thousand robots and five hundred drones have been lost." There are also 652 signal relay stations. ”

This is a big loss for the entire base. Chen Xu arranged two lines of defense, one with 2,000 robots, and three kilometers away, with 5,000 robots, and stronger fortifications.

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

At this moment, the robot lost nearly one-fifth.

There are also five hundred drones, a third of which are lost.

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

However, at this time, no matter how big the loss is, Chen Xu no longer cares about it.

…………

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

The original mission of the landing ship was to explore, and the original plan was that there would be a steady stream of reinforcements, so the amount of nuclear fuel brought with it was not much. Fortunately, the later supply ships had plenty of fuel.

In the past seven years, Chen Xu has expanded wildly, and his fuel consumption is very large, and he is about to bottom out.

Now, with a constant supply of fuel, you can spread the stall without any scruples.

This can be regarded as the second stage, and Chen Xu's plan is to build a controllable nuclear fusion power generation device. If he wants to do this, he must first fill up the front-end technology one by one. Going back in time, the sheer number of technologies that need to be lit up is daunting.

Roughly estimated, it will take ten years.

The underworld may have been frightened and did not send any more troops. Chen Xu didn't take the initiative to attack the underworld, but it didn't mean that he didn't do anything, he sent the clone out again and entered the underworld. The main quest still needs to be done.

Half a year later, the clone returned safely.

The forces of the underworld really didn't dare to do anything to him.

This time, the clone who learned the underground language brought back a lot of information about the underground world. Later, all major forces rushed to contact him, and this time he even learned the writing of the underground world, which can be said to be a huge gain.

After extracting the contents of the brain, Chen Xu sent the clone to the underground world again.

In this way, two years later, Chen Xu hollowed out the secrets held by the major forces in the underground world. It's unbelievably simple.

According to the records of the "Temple", a thousand years ago, this planet, like the earth, lived on the ground, and at that time, there was neither the clouds that enveloped the entire planet, nor the strong radiation.

Until one day, war broke out.

The cause of the war remains a mystery to this day. I only know that suddenly, a certain big country threw a nuclear bomb on another family, and in just one day, a nuclear war began. It was unexpected.

And this is only the beginning, and the next is a hundred years of war.

In this protracted war, in addition to nuclear weapons, there are also various newly developed super weapons, meteorological weapons, genetic weapons, etc., which are scrambling to be used.

The damage to the environment caused by the war was so severe that it became uninhabitable, and countries began to dig holes in the ground. This is where the Underworld comes in.

In the end, the small countries were almost dead, and only a few big countries were left to survive, and they really couldn't fight anymore, and the war was over. By that time, all humans had moved underground.

In the beginning, the underground of this continent was connected, and there was a subway. Until an unprecedented earthquake collapsed a large area of the underground world, killing and injuring countless people, and at the same time, completely cut off transportation.

The area of the thirteenth arrondissement is not small, enough to accommodate a population of millions. It would not have been impossible if we had been able to work together at that time to reopen the passage.

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

Chen Xu also got the entrance map of the underground world of the entire continent. The closest, five hundred kilometers away, is the entrance to District Twelve.

"These people's bones are too soft."

Yang Jinxia looked at the information and couldn't help but sigh. This is the fourth time she has entered the dream world, and it is also the tenth year that Chen Xu has entered the dream world.

"Even such a secret was voluntarily revealed."

Chen Xu said, "If they have a little backbone, they will not fall into today's fate." I have to say that this food manufacturing technology is quite thoughtful. ”

"If they hadn't spoken out, the clones wouldn't have been able to find the entrance to the basement."

In the underworld, there's another layer down there, and it's all about labs, manufacturing plants, and places to grow food. Corresponds to the living area on the upper floor, and the production area on the lower floor.

To enter 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, and the task of the clone is to collect intelligence, and will not take the initiative to cause trouble, so as not to delay the task.

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

The factories and laboratories on the basement level are largely abandoned, and only the planting area is still functioning.

The so-called people take food as the sky, and they can rule the thirteen districts because they control the planting areas and control the grain.

After Chen Xu learned that there was a production area underground, he sent a robot to search for it, and the people of those forces seemed to be frightened and didn't even dare to stop it.

In this way, Chen Xu got a large amount of technical information on the planet. A large part of it has been lost, after all, it is so old that many computers have been scrapped, and even the storage equipment has been completely damaged.

Of course, these things are just icing on the cake. He couldn't even learn the technology on the spaceship, let alone the technical information of the underground world, so at most he could use it for reference.

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

Yang Jinxia said, "I don't think there is a need to have too high expectations, 500 kilometers is not too far away. ”
