Several drones had already flew out and circled nearby for a while, but lost the trace of the black shadow.

There are many trees growing around it, and the environment is too complicated. The black shadow doesn't look big, so it's hard to find it if you hide anywhere.

The drone did not withdraw and continued to circle and was responsible for the alert.

"Take two robots to check if the monitoring hard drive is still there. If it is still there, bring it back." Chen Xu ordered Wang Zhu next to him.

Wang Zhu took his weapon and got out of the car.

"What is that?"

Luo Xiyun looked at the screen and was frozen on the image of the black shadow I just took. Although it was not clear in the thick smoke, it could be seen generally that it was like an elongated black figure, which looked a bit weird.

"It should be the little monster in this game." Chen Xu's tone was quite relaxed.

After a while, Wang Zhu came back, "The cameras were destroyed, the host and hard drive were destroyed. However, we discovered these things."

This news was somewhat beyond Chen Xu's expectations. It was not surprising that the camera would be destroyed, but it was a bit unusual to know how to destroy the host and hard drive. This means that the intruder is likely to understand these things, that is, the enemies he has to face have a certain level of technology.

This is not good news.

These thoughts flashed through his mind, and his face remained silent, and he looked at the thing that Wang Zhu brought over. It was a ball of kelp, with burning marks on it. It was trembling slightly like life, and green juice oozed out from time to time. It looked a little disgusting.

Was it the invader left behind?

In his impression, there was no such thing in the farm.

"Put it in a sealed container and take it back for research," he ordered, and asked, "What's going on inside?"

Wang Zhu replied, "All the animals raised were killed, and all the equipment inside was destroyed."

Chen Xu was even more sure of his guess.

Luo Xiyun said, "Let's go back."

"Okay." Chen Xu naturally would not refuse her proposal.

…………

After returning to the base, Chen Xu first sent Luo Xiyun back to rest, and then came to the control center again to start strengthening the prevention work of the base.

When he built a farm, he considered that there might be beasts coming in and installed weapons on the walls. Once the camera detects that there are wild beasts or the like, it will activate the weapon equipment and shoot them to death.

This design failed to stop the shadow, and he had to be vigilant.

If the black shadow touches the base and the equipment is destroyed, it is still a trivial matter, and it will be hurt by Luo Xiyun and the others, I will regret it.

"It seems that the iron ore must be developed in advance."

Chen Xu made a decision.

After all, the farm was raided this time and almost ambushed him. The biggest reason is that the information is not smooth. If the farm could be connected to the base, he would know immediately as soon as the black shadow appeared. How could it be like now, and he would not even see the enemy clearly.

This incident finally made him determined to build a network within his own sphere of influence.

Although he doesn't know how to solve the problem of wireless signal attenuation, he has other solutions. It's very simple. Just build a wired network.

However, this requires laying a lot of optical cables and wires, which requires a lot of human resources. More importantly, whether it is optical cables, wires, or corresponding supporting facilities, a complete set of production lines is required. This is not one or two, but it may be more than a dozen, or even dozens.

Take the insulator of the cable for example. First of all, there must be raw materials, such as commonly used polyethylene, which are processed from ethylene, while industrial ethylene is separated from gases produced in petroleum refining.

In other words, we must first find oil, from the mining of oil to refining, then separate ethylene from the gas, process it into polyethylene, and then make it into an insulator...

This involves many links, and each link may involve new links. If it continues to extend out in this way, it may eventually involve the entire industrial chain.

This is the era of large-scale industrialization. One link involves countless links. If it is stuck, it will not be produced.

Moreover, after the production line is built, people will always need to control it. The human resources in the base are too tight now, and there is not enough.

Therefore, Chen Xu has never made up his mind to do this.

Now, he couldn't help but hesitate. No matter how difficult it was, he had to do it. The enemy had appeared, and he felt that the black shadow would be quite difficult to deal with.

After he readjusted the base's security system, he came to a medical laboratory.

"Mr. Chen."

After Chen Xu entered the door, three biochemical people in white coats stood up and saluted him.

He waved his hand and signaled that they didn't have to be too polite. He asked about the serious matter, "Feng Song, have you developed any research on the sample I just sent?"

The youngest of the three said, "This should be the tissue of some kind of organism, but its cell structure is very strange. There is no match or even similar one found in the biological database. It is a completely new type of organism."

Chen Xu frowned when he heard this. There were no similar creatures in the biological database. What kind of thing would it be? Even the rockets on the transport truck could not be killed, and the speed displayed when the black shadow fled.

The enemy I am about to face is really a bit beyond imagination.

He said, "Put down the other work you have on hand for the time being, and start researching it first. I will notify me immediately if it has any results."

"OK."

When Chen Xu left the medical laboratory, he was thinking about how to solve the problem of population shortage.

The only one who can really come in handy for this huge medical laboratory is Feng Song.

The surname Feng was the ninth batch of biochemical people. At that time, he lacked the subordinates who could stand alone, so he gritted his teeth and trained a group of fourth-level biochemical people. The cultivation cycle of this level of biochemical people is as long as one and a half years.

Each of these ten people is responsible for a field, biological laboratories, physics laboratories, chemistry laboratories, etc.

As for the other two, they are secondary biochemical people, who are assistants, and do some simple and repetitive work in the laboratory.

The output of the biomanufacturing room is limited, with only ten cultivation tanks. The problem he faces is whether to cultivate first-level biochemical people with short growth cycles or cultivate advanced biochemical people with more professional knowledge but long growth cycles.

When Chen Xu returned to the living area, he had already made a decision.

Cultivate natural persons.

The shortest cycle of cultivating natural persons is used in a biological manufacturing room and can only be born in one day, because it only takes him to grow into infancy, without ripening into adulthood, or instilling knowledge. This is the most time-consuming.

If all ten cultivation tanks are used to cultivate natural persons, they will have more than 3,000 people in a year. Moreover, natural persons have the ability to reproduce, and after twenty or thirty years, the population will be doubled after the second generation is born. If legislation encourages more children, it will be fine.

Before, Chen Xu had not been able to make up his mind. It was not entirely a matter of too long training cycle. More importantly, the Constitution stipulates that the free will of natural persons is not violated. Even if he has the highest colonial authority, he cannot use machines to brainwash natural persons.

When a natural person grows up and has the ability to think independently, he must spend a lot of energy to consolidate his position.

Moreover, doing so is equivalent to creating a human society. Just thinking about it makes you feel a huge pressure.

…………

Chen Xu thought about these troubles, before entering the living area, he let out a long breath and left all the things behind.

Anyway, it was just a game. To him, it was not as important as the woman inside. He relaxed the muscles on his face and made himself smile more naturally before walking in.

At this time, it was just night.

He entered the hall and smelled a scent. When he looked into the kitchen, Luo Xiyun was standing in front of the stove, holding a spoon, and savoring the taste.

The hair behind Luo Xiyun's head was tied up, and Chen Xu could see her side face. His focused look was less cold and arrogance than before and more quiet.

At this moment, the tenderness she showed inadvertently hit Chen Xu's heart.

"It seems a little faded." Luo Xiyun said to himself, as if he had all the feelings. He turned around and looked over. When he saw him, his expression changed. He became colder and did not say hello to him, and put the spoon back.

She took out the lunch box, packed the soup and food, and turned back to her room. She didn't say a word to him during the whole process.

Chen Xu walked into the kitchen and saw that half of the rice was left in the pot, there were vegetables and soup in the basin, which was obviously reserved for him.

There was a warm current in his heart. He took out the bowls and chopsticks, stood by the stove and started eating. After taking a bite, he seemed to have returned to his first dream...
