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

"Can I ask for anything?"

"There are two principles to follow. First, your work cannot interfere with our original plan, such as lifting the technological blockade or stopping the pursuit of Luo Ji. Second, your request must be within our capabilities. Sophon can only intervene at the micro level and cannot interfere at the macro level. Therefore, you can only ask ETO to assist you in this regard."

Lin Xuan nodded slightly, which was similar to what he thought.

"It's okay. My requests will not violate these two principles."

"When I went to the Wallfacer hearing, you should have heard that I wanted to build an underground city."

"To defend against our attack on Earth?"

"No, no, I have another use for it, so don't worry about it."

Lin Xuan didn't know what was happening to her. As a wall-facer, she could chat with the Trisolarans as if they were her own people.

“This is actually very difficult to do.”

Tomoko replied.

"I don't understand. What kind of help do you want us to provide you? As far as I know, you have already completed the design concept of the dungeon. What other factors can prevent you from carrying out this plan smoothly?"

"money!"

"What is money?"

Lin Xuan was stunned, and then she remembered the development gap between the Trisolarans and Earth civilization. Perhaps they really didn't know what money was, or perhaps this ancient thing only existed in their history books.

"A substitute for material transactions, that is, a currency used to facilitate the exchange of materials between individuals of the same civilization."

"understood."

"Have you Trisolarans never had the concept of currency?"

“Yes, but our currency exchange system is based on demand and contribution. All actions should be based on the interests of the entire ethnic group. Individual interests should not override the interests of the group.”

Lin Xuan finally understood what the salvationists were thinking.

If we ignore the humanistic factors, the Trisolaran social system is indeed amazing, and all their actions are based on absolutely rational considerations, but this will also be the biggest hidden danger that hinders the progress of their civilization.

To achieve a short-term leap in science and technology, three conditions are required: energy storage, contradiction, and direction.

Energy storage refers to the way a civilization uses energy at a certain stage. Whether it is the First Industrial Revolution or the Second Industrial Revolution, it started with a completely different way of using energy than before. It is like firewood for lighting a bonfire.

Contradiction is the spark that ignites the firewood. Contradiction is the unity of opposites, which is also one of the major factors in promoting the development of science and technology. The three-body people have similar thinking and their communication cost is very low, but humans are different.

Compared with the Trisolarans, humans' communication efficiency is extremely low. The same sentence can even express different meanings at different times and in different scenarios.

Communication between humans can only achieve a general consensus on meaning, but an individual can never express his or her complete meaning to another person.

China even treats Chinese language as a major subject with the aim of reducing the difficulty of communication between people.

The result of this is the emergence of conflicts among humans. Where there are conflicts, there will be struggle, and where there is struggle, there will be accelerated development of science and technology.

The direction is easy to understand, it is the process of scientific discovery of laws.

Now the sophons have locked the end of physics, preventing humans from discovering the laws of nature, and they themselves cannot have internal conflicts due to the nature of their own civilization.

As a result, both civilizations fell into an embarrassing situation of scientific stagnation.

"Back to our previous question, I need ETO to help me provide enough funds to build the underground city, but judging from the current situation of mankind, the economic system is on the verge of collapse, so in fact, I need you to provide more supplies."

“That’s going to be a huge number.”

Chiko said.

"Choose one of the two. If all else fails, you can help me build Reach. You will provide less materials for that project."

"veto."

"Really? I've calculated that the first scientific research spacecraft of the Asian Fleet, the Seeker, will be completed soon. By then, as long as we can find available materials from other planets in the solar system, the establishment of Reach will be much smoother than expected. Would you like to consider taking this job?"

"Observer, we accept your previous conditions."

Seeing that she failed to fool the Trisolarans, Lin Xuan didn't say much.

The construction of the dungeon was carried out simultaneously with the construction of the Reach Space Station.

Lin Xuan is responsible for the construction of the main structure of the three underground cities.

The three cities are located in London, New York, and Los Angeles.

The choice of the city was based on the results of a public vote, and Luocheng was far ahead in the votes. Even Lin Xuan did not expect this, as he thought it would be in Shuzhou.

Since the underground city design drawing given by Lin Xuan looks like an inverted city that is a mirror image of the one on the ground, the underground city project is also called the "Mirror Project".

……

"Shi Qiang, thank you for saving me again!"

Luo Ji sat in the hibernation cabin and seemed very grateful to Shi Qiang.

He couldn't remember how many times Shi Qiang had saved his life.

Since the last attack, ETO seemed to have completely given up on assassinating Luo Ji, so PDC took this opportunity to arrange Luo Ji's hibernation.

Shi Qiang wanted to light a cigarette, but the staff member next to him glared at him.

Only then did Shi Qiang realize that smoking was prohibited in the hibernation center.

"Okay, brother, let's save our words of gratitude for when we meet again in the future."

Luo Ji was stunned.

"You want to hibernate too?"

Shi Qiang nodded slightly.

"Lin Xuan insisted that I hibernate with you, saying that I could continue to protect you in the future."

"I told you to stop talking nonsense. I am affiliated with the PDC, not Luo Ji's personal bodyguard."

"The results of it?"

"As a result, I applied to the PDC as a Wallfacer to let me hibernate with you into the future. Damn it, the policy of delaying retirement to 90 years old is really going to happen to me!"

Shi Qiang was stunned when he learned about Lin Xuan's move, but there was nothing he could do. He also knew that the road ahead might be more difficult. Since Lin Xuan said so, he couldn't refuse.

"I don't remember you have a son, what about him?"

"You mean Shi Xiaoming?"

"Correct."

"He's in jail. I just found out about this. He was in jail for selling fake insurance and committing fraud."

"Do you want me to get him out? With my identity as a wall-facer, this is still possible." Luo Ji asked.

Shi Qiang curled his lips. He subconsciously wanted to take a puff of his cigarette, but then he remembered that the cigarette was not lit yet.

"Brother, you don't have to worry about this. If you really want to get that guy out, I can do it with my power, but it's a matter of principle."

"I can get away with it for him for some things, but not for this one. He is an adult and should be responsible for his own actions."

Shi Qiang is not a person with a strong sense of justice. When he was a policeman, he ignored the safety of hostages, used gangsters, tortured and extorted confessions, etc. He was a person with a "bad record".

If Chang Weisi had not recruited him to the PDC, he might have had nowhere to go after being expelled from the police force.

But Shi Qiang has always had his own set of principles in doing things, which is why he has been entrusted with important tasks time and time again.

Shi Qiang took a last look at Luo Ji and then helped him close the lid of the hibernation chamber.

"Okay, see you in the future!"

"See you in the future."

……

Chapter 66 Accommodating 20 Billion People

Crisis Era: 10 years.

With the help of Chieko, Lin Xuan's speed is quite fast.

"The progress of the Mirror Project is much faster than expected, but it also brings good news and bad news."

At the Wallfacer hearing, Lin Xuan crossed his legs and sat leisurely in his seat, recounting his work for the past year.

The current Wallfacer hearing has truly become a meeting where he speaks and others listen.

"Let's talk about the good news first. I haven't heard any good news that makes me happy in almost one or two years." said Olivia, the rotating chairperson.

She was the former representative of the Republic of Italy. Ever since the influence of the British Empire began to radiate throughout Europe, the situation of the Republic of Italy has become somewhat awkward.

The financial crisis has completely destroyed the entire European Union. Italy has some experience in this regard, so the government has been exercising restraint on the issue of inflation, but with little success.

It won't be long before reality overlaps with history, and the situation of a loaf of bread costing 50 marks will be repeated in Italy.

"During the mining process of the Mirror Project, we discovered a large number of rare minerals, which may help alleviate the upcoming financial crisis to a certain extent."

Upon hearing the news, everyone present's eyes lit up.

"As I said long ago, building an underground city is a good thing that kills two birds with one stone!" the British Empire representative said excitedly.

Lin Xuan glanced at him. If he remembered correctly, this guy was the first person to stand up and oppose his building of the underground city.

"Don't be too happy, gentlemen. There is still some bad news waiting for you."

The meeting room suddenly became quiet, waiting for Lin Xuan's next words.

"Our budget for Reach is far below the actual standard."

"This is impossible."

The Eagle Sauce representative was the first to refute.

"China, us, and the Russians all participated in the construction of Reach. The data model was established from the beginning. Even if there are deviations in the budget, it will definitely not be too different from the planned schedule."

"Yes." Chinese representative Zhang Huaimin also agreed with this statement.

"Are you trying to get kickbacks from the Reach project?" the island nation representative asked suspiciously.

Lin Xuan smiled.

"Mr. Chairman, could you please cut off the communication between this meeting and the outside world?"

Olivia nodded.

"Of course that's no problem, Mr. Wallfacer."

Soon, the communication of the Wallfacer hearing was cut off from the outside world, and some reporters present were forcibly stopped from continuing to film.

The door was closed and no one knew what Lin Xuan was going to do.

If he was trying to conceal his next words, then Tomoko would also hear them. Once the information was leaked, his words would be concealed in vain.

After everything was ready, Lin Xuan said.

"I never intended to build Reach as a space station from the beginning."

Shock value from the Chinese representative +50.

Shock value from the island nation representative +50.

……

Lin Xuan smiled.

"Everyone, think about it, why did Wang Miao give this space station this name? Zhiyuan... It represents the fate of this space station from the very beginning."

Everyone pondered for a moment, and then Zhang Huaimin, the representative of China, was the first to react, followed by Eagle Sauce, and the Bear...

"Asshole, you are an escapist. This plan is not allowed by the Wallfacer Act!"

The representative of the British Empire slammed the table and shouted.

Representatives from other countries also condemned Lin Xuan's behavior.

Lin Xuan seemed to have known that this group of people would have this reaction. He waited until these people's excitement had passed before speaking.

"What if I take away all of humanity? Is that still escapism?"

There was dead silence in the venue.

"This is impossible."

Huaxia representative said.
