Let you be the wall-facer: you turn around and join the Three-Body Problem?

"Principal Liu, the sowing of the No. 3 experimental field has been completed, and we can proceed to the next step of cultivation."

Zhang Beihai took out a box of purple fruits with thorns from the trunk of the spacecraft and placed it on the ground.

These strange-looking fruits are Liu Chang's latest research results. When you eat them, it feels like chewing meat.

At the same time, it can also replenish most of the nutrients needed by the human body, and can be said to be a must-have choice for daily snacks.

Food is the most important thing for people. No matter where you go, eating is the most important thing.

There are many poultry and livestock in the Navigator's breeding cabin that Liu Chang brought from the Earth before leaving. However, eating these things alone cannot meet the dietary consumption of a human civilization, so equivalent substitute species must be available.

That’s right, human civilization.

After completing the last task assigned to him by Lin Xuan, Zhang Beihai led everyone on the ship back to Green Star and re-suppressed the development of tree civilization.

A planet cannot accommodate the existence of two civilizations at the same time, even if the development of the Treeman civilization is guided by the Human Alliance.

In order to avoid conflict between the two civilizations, Zhang Beihai chose to suppress them directly. Although the Treeman Civilization and the Human Alliance shared the right to reside on Green Star, the Treeman Civilization did not have the right to govern and could only obey the government.

This common understanding was reached after Zhang Beihai deployed a railgun above the Green Star.

In order to ensure the absolute safety of the treeman civilization, Zhang Beihai even cut off most of their technological development. If some technology trees were not profitable to the Human Alliance, the technological progress of the treeman civilization would probably have to be completely banned.

The political structure of the Human Union was based on part of the Earth Union.

For example, the presidential system, but Zhang Beihai still prefers everyone to call him captain.

Under Zhang Beihai, Chu Yan, Liu Chang and Dongfang Yanxu formed the same three-seat system as Fleet International.

Further down, the coordination rights of departments at all levels are handed over to AI Cheng Xing.

In general, the entire human united political system is like a pyramid.

Government affairs are reported to AI Chengxing by the lower-level departments, and AI Chengxing gives options. The options are then voted on by the three seats at the center, and the results of the vote are then decided by Zhang Beihai.

Then, following this process, the data is summarized from the hub to the AI.

The three seats have the right to vote and elect on all matters, even including the optimization of Zhang Beihai's own rights.

If the bill is passed unanimously by the three seats, even if Zhang Beihai himself refuses, it will still be implemented according to the final result of the three seats.

This is a layer of deterrence that Zhang Beihai set for himself.

He knew very well that he was just an ordinary person, and the only reason he could stand in his current position was his determination to sacrifice everything to achieve his goal.

But precisely because he is an ordinary person, one day he may be afraid that he will become greedy for power and refuse to step down from this position. After all, people always change.

Therefore, he set up a deterrent for himself while he was still conscious.

"If one day, my existence affects the development of the human union, please send me to the guillotine with your own hands."

Chapter 278 Historical Overlap

When dealing with non-human races, Zhang Beihai's strategy has always been simple, direct and efficient.

"The Human Union does not need slaves."

In the first year after Green Star completed its infrastructure construction, the first thing Zhang Beihai did was to send out a reconnaissance fleet to search for possible life in nearby star systems.

Once the observation window finds that the planet may have life, the orbital cannon will be used to destroy it without any further ado.

Only after ensuring that all life on the planet has been almost wiped out will Zhang Beihai send a landing force into the planet to explore whether there are any rare metals that can be mined.

The Human Union has assigned levels to these planets.

If the planet has no life, it is defined as safe.

If the planet has life but no intelligence, it is defined as needing to be colonized.

If the planet has intelligent life but does not have the ability to enter the universe, it is defined as needing to be cleaned up.

If there is intelligent life on the planet and it has the ability to observe the universe, it is defined as dangerous or must be wiped out.

Later, everyone found that this efficiency was still not high enough, so they simply skipped the detection process. As long as they sensed life, they would treat it equally and kill it all.

Some people have questioned Zhang Beihai's decision, believing that doing so would be nothing more than a massacre, and that launching genocide too frequently would also consume a lot of energy from the spacecraft.

Zhang Beihai had no intention of arguing with him. After all, in his opinion, the safest way was to nip the threat in the bud.

As for the accusations made by the People's Union against him, he didn't care. Unless such behavior made Liu Chang and others who held the third seat feel dissatisfied, he would give a proper explanation.

Zhang Beihai is like a calm killing machine. All his actions are just to achieve the goal of keeping people alive.

In order to achieve this goal, he can do whatever it takes.

Some people compare Zhang Beihai and Wade, but in fact, the two people's ideas are completely different.

Thomas Wade was a complete madman who had no regard for the feelings of the people he was protecting. Zhang Beihai, on the other hand, was just fulfilling his duty as a soldier.

With the assistance of the Human Union, the two civilizations developed extremely rapidly, and Green Star also gained unprecedented vitality.

But Liu Chang discovered a problem, that is, how come the development of this tree man civilization is getting closer and closer to the early development of human beings?

The development speed of the tree people civilization is very fast. Since Liu Chang met these tree people, less than a hundred years have passed, but the technology of these tree people has developed to the point where they can break free from the constraints of the ground.

It took humans thousands of years to develop to this point.

But looking back at history, Liu Chang discovered that the history of tree people over the past few decades has a high degree of overlap with human history.

The Industrial Revolution, the Enlightenment, the fall of the feudal system...

It was as if Liu Chang was quickly reviewing the history of mankind from primitive times to the present day again.

But what’s interesting is that if you compare the history of Tree Man civilization with human history in the form of a timeline, you will be surprised to find that the closer the development of Tree Man civilization is to human civilization, the slower its development speed becomes.

The speed at which they develop is like a huge mountain.

In the early days when Liu Chang and others did not meet, the development speed was extremely slow and the country remained in primitive society for a very long time.

Later, after Liu Chang and his companions arrived at Green Star, the development speed of the Tree People civilization began to rise rapidly, until Zhang Beihai returned, when it began to decline and even reach a bottleneck.

At first, Liu Chang thought that this was due to the suppression of them by the Human League, but Shi Qiang saw the crux of the problem at a glance.

“Isn’t this just copying homework?”

Shi Qiang lit a cigarette and took two puffs.

"Old Liu, the reason why the tree people civilization developed so fast in the early stage was that they were just copying the homework of our ancestors. Now there is nothing for them to copy, so naturally their development is slow."

Liu Chang was silent for a moment, and then looked at Shi Qiang who had a smug look on his face.

"You're right, but there's a question. How did these tree people get to copy the homework? At that time, there were only the two of us on Green Star. I never told you about the history of the Earth and human development. Could it be that you told me?"

Shi Qiang was shocked when he heard this!

"Old Liu, you can't slander me, Shi Qiang. You know I'm the most tight-lipped person!"

Liu Chang rubbed his head helplessly.

"I know that, but it's not you who said that, nor is it me. They can't just develop into what they are now out of thin air. You have to think of a way, otherwise we won't be able to clear ourselves of the suspicion of leaking the information."

When Shi Qiang heard this, his expression suddenly froze.

"My goodness, we've been in jail for several years, and we finally waited for Zhang Beihai to come and rescue us. Why do I feel like we'll be in jail again in a few days?"

The two stared at the two timelines in front of them, wondering what went wrong.

Suddenly, the stiff expression on Shi Qiang's face changed slightly, and he turned his head to look at Liu Chang.

"Principal Liu, I suddenly remembered a case I took over a long time ago. There was a couple who were both imprisoned for intentional homicide. They were both orphans and had no relatives, but they had a child who was less than one year old and needed to be raised."

"We had no choice at the time, so we sent the child to a boarding family to be raised. Later, when I checked the files after hibernation, I found that the child had also been imprisoned for intentional homicide."

"What do you want to say?"

"What I mean is that this child has rarely seen his parents since he was a child, but he still committed a crime and went to jail. This actually has nothing to do with whether his parents taught him or not. Once this kind of influence appears, it will subtly affect you. So is it possible that the Tree People civilization has been influenced since the first time they met us and they can't walk out of their own civilization path?"

Liu Chang listened to Shi Qiang's analysis without commenting.

"You have a point, but this analogy is not appropriate. After all, genetic factors may also be one of the triggers of crime. There are too many influencing factors, and it is not necessarily easy to determine what is playing a role."

"Do you remember Tianchen? He was the observer number five. When he came to see us, he mentioned something to us."

"Knowledge Sealing Criteria?"

"Yes, the knowledge sealing code. He was deliberately avoiding some things at the time and didn't tell us. I suspect he did it to prevent us from being influenced by them, just like the current tree civilization."

"But there is one thing I can't understand. If we are influenced by him, so what? It should be a good thing for him, but why would Tianchen avoid this matter?"

"Besides, I always feel that Tianchen has no good intentions!"

Chapter 279 Only Destruction

"The ship has entered the Elbato Nebula and is activating internal navigation."

"Navigation Landing Site: Earth-3."

"Space jump ready, sending jump request..."

"3...2...1."

"Jumping begins!"

Inside the cabin, there was a slight shaking sensation, and the doors began to be sealed layer by layer.

The Earth Union has also been researching this kind of space jumping technology, but the results are not perfect.

At least there is still a long way to go before it can be officially put into use.

The current technological level of the Earth Union's civilization can only be considered as the middle or late stage of a Level 2 civilization, and it still has a long way to go before it can become a Level 3 civilization.

But the other three Earths are different. They have already entered the technological realm of Level 3 civilization. Some have even stayed in Level 3 civilization for a very long time. They are only half a step away from becoming a Level 4 civilization like the Singer.

Technology of this level can have a say even in the Carbon-based Federation.

"By the way, I haven't asked you yet, why did you go to so much trouble to get me from Lin Xuan?"

Lin Xuan turned her head and looked at No. 3 who was operating the spacecraft with his eyes closed, and asked about the doubts in her mind.

"This is a long story. Before you came, did Lin Xuan tell you about Earth No. 1?"

Lin Xuan shook her head.

What are you introducing?

What should I let him know?

At this moment, Lin Xuan suddenly felt fortunate that she had pretended to be Bai Bing and came with No. 3. If Bai Bing had come alone, wouldn't her knowledge of nothing have been exposed?

Number Three looked at the confused "Bai Bing" in front of him and was speechless for a moment.

"Forget it. It seems he forgot to tell you. It doesn't matter. We still have some time before entering the starport. I can introduce it to you slowly on the way. If you have any questions, you can interrupt me at any time. After all, I don't know how much you know about Earth No. 1."

When Lin Xuan heard this, her eyes suddenly lit up.

"no problem!"

This is what I'm waiting for!

"There are six Earths. Excluding Earth No. 4 where you are, there are three left."

"They are Earth One, Earth Two, and Earth Three, which I rule."

"These three Earths have now developed to the level of Level 3 civilization and have the ability to move stars. However, if they want to break through to Level 4 civilization, they need to compete in this ancient battlefield selected by the administrator to determine the final winner."

Having said that, No. 3 thought about it, and the viewing window on the outside of the spacecraft was opened.

Through the viewing window, Lin Xuan saw a scene that shocked him extremely.

A black hole!

A black hole that is tens of thousands times larger than the sun is located at the center of this space.

And around it, three planets are slowly rotating around the black hole, as if they regard the black hole as a part of their star system.

Various densely packed facilities are being built around the three planets.

Space stations, starports, ring-belt residential areas...

If Lin Xuan had previously thought that the Earth Union's defense had been armed to the teeth, now it seemed that compared with these three planets, the Earth Union's defense was as ridiculous as the sticks and stones of primitive people.

Without asking, Lin Xuan could guess that these three planets were the three Earths controlled by three observers.

"This place, on the star map, is called the Elbatto Cluster. There are about 3410 permanent planets and 17 permanent stars. Our civilization was the first to arrive here. At that time, the Elbatto Cluster was just an undeveloped wasteland."
