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

"Because the deterrence mechanism exists." Zhang Xiang answered without hesitation.

"Why are the Trisolarians afraid of my brother?"

"Because Lin Xuan is strong enough."

"So under what circumstances would this situation occur?"

Zhang Xiang thought about it.

"It seems that there is only one possibility, something happened to Lin Xuan."

"If the Trisolarans had a way to deal with your father, or if your father himself had problems, it might lead to the Trisolarans directly attacking the Earth instead of being afraid of him like they are now."

"But Lin Xuan is different. If they had a way to deal with Lin Xuan, given Lin Xuan's personality, she would definitely choose to take the initiative to attack. But now both sides are silent. The problem should be with Lin Xuan herself."

Luo Congmin nodded slightly and slowly stretched out three fingers.

"There are three speculations. First, Lin Xuan and the Three Bodies are mutually restrained for some reason. Second, Lin Xuan was replaced by someone else. Third, both of the above speculations are correct!"

Zhang Xiang's breathing suddenly became rapid.

"Then...what should I do? Now that you mention it, it seems like I haven't seen Lin Xuan for a long time. He...won't really."

Luo Congmin sighed.

"No matter what, Lin Xuan must have been in trouble, but we can solve the problem directly from the root."

"How to solve it?" Zhang Xiang didn't understand.

"So, if you were a Trisolaran, what would you most likely do after Lin Xuan's threat was gone?"

Zhang Xiang thought about it and then said.

"To take control of human power?"

However, Luo Congmin shook his head, indicating that Zhang Xiang's answer was wrong. Without waiting for Zhang Xiang to think more, Luo Congmin directly gave the answer.

"Controlling the human political power has nothing to do with Lin Xuan. Lin Xuan never interferes in the politics of the Earth Alliance. If they rashly want to control the human political power through Lin Xuan, it would be absolutely stupid. The Trisolarans... should not be that stupid..."

"Then it seems that he only has one target left."

"Sword bearer!"

"Unless the Sword Wielder is eliminated, all actions of the Trisolarans against humanity will be meaningless."

"The only solution is to get rid of the Sword Wielder."

Zhang Xiang did not comment.

"This is difficult. Let's not talk about whether they have the ability to assassinate the Sword Bearer. Just getting close to the Sword Bearer could cause the broadcast to be transmitted. The Trisolarans will never take this risk."

"Who said that the only way to deal with the Sword Wielder is assassination?"

"What should we do? Is there any better way?"

Luo Congmin raised his chin.

"The deterrence itself does not lie in the ability of the broadcast, but in my father as a person."

"There is no need for the Trisolarans to target the position of Sword Bearer. They can just target my dad. If something happens to my dad and he loses his position as Sword Bearer, then humanity will be in great danger."

Zhang Xiang nodded slightly, thinking that what Luo Congmin said made sense.

"So...what's the specific plan?"

Upon hearing this, Luo Congmin couldn't help but give Zhang Xiang a blank look.

"How could I know? I'm not the head of the Trisolarans. Anyway, if I were to do it, I would most likely ask humans to elect someone who has no deterrent ability to replace my father. In this way, the Sword Bearer would be in name only."

"But these are just my guesses. As for the specific plans, how would I know?"

Chapter 176 Treeman Civilization

March of the 80th year of the Deterrence Era, 3 AD.

Zhang Beihai walked quickly through the spherical cabin of the ship and came to the living area in the rear half.

This is a place that provides leisure and entertainment for the ship's crew. The venue is similar to a sake bar on Earth. The liquors stored inside are all aged wines that have been sealed for hundreds of years. One sip of it is absolutely refreshing.

At this time, Chu Yan was already waiting here. When he saw Zhang Beihai coming, he smiled and handed a glass of wine to him.

"I still need to command the battleship, so that's not necessary."

Zhang Beihai rejected Chu Yan's kindness and poured himself a glass of boiled water.

"Boring."

Chu Yan didn't make things difficult for the other party. After spending the past few years together, he already knew Zhang Beihai's character very well. He did everything meticulously, just like a clockwork machine.

"The ship's command system can be completely handed over to Cheng Xing. With the control capabilities of that AI, it can even do better than you and me. Besides, the spacecraft will stay in the orbit of this green planet for many days, so you don't have to worry about it."

"Ok, I know."

Zhang Beihai responded casually, but Chu Yan knew that this guy was just trying to fool him.

"How long will it take for Dashi and Principal Liu?"

"I only gave them the last four years. If there is still no progress in the research within four years, they will have to leave temporarily."

More than ten years ago, after the observer Tianchen left Green Star, Principal Liu said that he wanted to study this planet.

After all, this is the first time that human civilization has seen the existence of another human civilization.

So the research began.

After a series of terrain surveys, Principal Liu discovered that this planet was almost identical to the Earth he and others knew.

Before they were destroyed by Willow, the planet's technology tree had almost developed to the nuclear age of mankind, and was only one step away from developing controlled nuclear fusion.

However, the appearance of willow seeds cut off all possibilities.

However, this also verified a new theory for Liu Chang, that is, the environment does change as people change.

Yang Dong had done this experiment a long time ago. If there is no life on Earth, then the Earth will eventually become a wasteland.

It is precisely because of the existence of low-entropy life that we have the Earth we have today.

The same is true for this planet. When human civilization emerged, their environment had the same resources as our own Earth, such as oil, coal, monsoon climate...

These are things that come after life appears.

So Liu Chang came up with a new research topic. In the past, humans were the masters of this planet, so this kind of environment came into being. Now that the masters of this planet have become willow trees, what changes will happen to the environment of this planet?

Thinking of this, Liu Chang immediately contacted the three tree people and asked them to move towards the path of transforming the planet's environment. Based on the actual conditions of the planet, see if they can develop a technology tree system of their own?

Liu Chang did it as soon as he thought of it. He asked Cheng Xing to wake up a group of biological researchers to arrive at Green Star together and begin to track and study this new civilization.

But the formation of a civilization requires hundreds or thousands of years of accumulation. Although the development speed of the Tree People civilization is very fast and it has the technical support of humans, it may take many more years to produce substantial changes to the planet.

In desperation, the Navigator had to stay here for more than ten years, quietly waiting for changes to occur.

However, during this period, Liu Chang also discovered some very interesting things.

The Tree People seem to be very interested in the music and works of art of human civilization, and the more they understand these things, the faster their technology develops.

This discovery was purely accidental.

At first, after Shi Qiang found that he had nothing to do on this planet, he began to brag to the Triangle Tree and other tree people, telling them stories about his time as a criminal policeman.

"I once took over a case where a woman cut off her husband's genitals. Do you know what weapon was used? A fish, a tilapia frozen in the refrigerator. After the fish was frozen hard, the row of spines on its back was like a knife." Shi Qiang said, and gestured twice with his hands.

"What is a refrigerator?"

The tree people's focus was obviously a bit strange, but considering that they had never seen a refrigerator, Shi Qiang had to start explaining to them the relationship between refrigerators and compressors.

As a former criminal policeman from the Intelligence Department, Shi Qiang still understood some basic mechanical principles. He just looked uneducated on the surface, but if you think about it carefully, you will know that the person with the lowest education who can work in the PDC should be Lin Xuan.

After a while, the tree people began to deduce some basic scientific knowledge from Shi Qiang's story, and soon they had their first creation.

It was something that looked similar to a Chinese rolling lantern.

The overall shape is spherical, and the sphere is formed by branches, and the part wrapped inside has a tree seed as the core energy device.

This thing absorbs energy through photosynthesis and can keep running forward. Although Liu Chang has not yet thought of its specific use, this is the first invention of the tree people, which surprised Liu Chang a little.

He quickly asked the team members to upload some stories and works of art of human civilization into the storage chip, and then instilled them into the tree man.

Something unexpected happened. In just three months, the development of the tree man civilization rose at the speed of a rocket.

They even built a magnificent building of their own on the equator of the Green Star, which stunned the crew of the Navigator.

"Technology explosion!"

Liu Chang looked at the giant building about six stories high in the distance. The structure of this thing was a bit like a bird's nest, but the steel bars were all replaced by thick branches.

This is the real bird's nest.

Humankind has experienced this rocket-like speed of technological development at least three or four times, so it is not unfamiliar to us, but Liu Chang sees something more profound in it.

"What triggered the technological explosion of the Treeman civilization? The answer is obvious."

Renaissance!

Human cultural artworks provided the Tree People civilization with sufficient imagination, which enabled their technology to advance rapidly in a short period of time.

The same is true for the premise of technological explosion in the development of human civilization.

Therefore, by comparing the situations of the two civilizations, Liu Chang obtained an axiom!

The premise for technological explosion is the accumulation of humanities and social sciences, and ideological enlightenment guides the future of science and technology.

Chapter 177 This is part of Lin Xuan's plan

"Hello, my name is Cheng Xin, I want to interview for a job..."

This was the 41st job resume Cheng Xin submitted, and as expected, she was rejected again.

After three months at the shelter, Cheng Xin still hasn't found a decent job. Fortunately, there is enough money in her bank account to last her almost half a lifetime, otherwise, just eating would be a problem.

Cheng Xin's education and abilities were quite outstanding. Although two centuries had passed, she was definitely not in a state where she couldn't find a job.

Where the problem really lies is her resume.

Former PDC member, senior technical advisor to PIA.

This identity almost has the words "remnants of the previous dynasty" written on his face.

Although nearly two centuries have passed, the pain that PDC brought to people has not been eliminated. Therefore, the middle and lower levels are more hostile to PDC officials, and only the upper level does not care much.

The reason is simple, because senior officials only care about gains and losses, and rarely tie the rise and fall of a dynasty or a country to their own goals.

Just like in the era of the United Nations, most of the stars in the domestic entertainment industry are descendants of the Eighth Emperor. There are quite a few PDC officials who hold important positions in the Local Union. They even love the Local Union era more than the people of the Deterrence Era.

That's why Luo Congmin doesn't take their identities so seriously.

After a person leaves his original group and joins another one, the first thing he does is to ridicule and belittle the group he once belonged to. Only by devaluing the former group to the point of being worthless can they highlight their foresight in leaving that group and how right it was to leave.

But the grassroots don’t think so. Their hatred for the PDC is real, and almost no one has a good face towards these former PDC officials.

After being rejected again, Cheng Xin has been considering whether she should start her own business.

She had a lot of money, but Cheng Xin knew that starting a business was not something she was born to do.

She still prefers to live a stable life, go to work every day, do something she likes, and have a small home of her own. The repetitive life does not make her feel bored, but makes her feel at ease.

She was born to be a public official. If it weren't for the political review, which would have been almost impossible to pass, Cheng Xin would have signed up for the local civil service examination long ago.

Cheng Xin is an orphan and has been without parents since childhood.

Before being adopted, she had been living a homeless life with no hope for the future.

Later, even though she was adopted, she still lacked love, or perhaps it was her deformed childhood that made her unable to obtain love, which made her remain single until she graduated with a doctorate.

She has many admirers, but she always treats them with respect. Yun Tianming is one of the few people she has memories of.

Cheng Xin didn't know why she remembered Yun Tianming. It might be because he also worked at PDC. It was a pity that the man later became a member of the Ladder Project. He was really great, which changed Cheng Xin's opinion of him.

The more a person lacks something, the more he desires it.

The experience of lack of love in her youth pushed Cheng Xin to an extreme. She longed for a stable life, a stable family, a stable job... and even a stable peace.

Moreover, she will spread her love to the people around her, because she once lacked this kind of thing, so she hopes to bring it to the people around her.

This is the other extreme.
