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

"Teacher Luo, what are you doing here?"

Zhang Xiang came from behind and waved his hand in front of Luo Ji.

Luo Ji couldn't help but roll his eyes when he heard this.

"There's a wall in front of me. What can I do?"

Zhang Xiang was stunned.

"You are cosplaying as the Wallfacer!"

"Zhang Xiang, your ability to find something to talk about has improved over the years."

Luo Ji couldn't remember how many times Zhang Xiang had come to see him this week.

This may be the tragedy of the immortals. Except for himself, all his friends have passed away one after another over the years. Except for Shi Qiang, almost all of Zhang Xiang’s former comrades-in-arms have turned into a pile of bones.

Therefore, Luo Ji did not seem too disgusted with Zhang Xiang's arrival. They all belonged to the AD era, and were old guys in the Deterrence Era.

In this era, it is probably only the two of them who can understand each other.

When he thought of this, for some reason, Luo Ji felt a wave of sadness welling up in his heart.

"How pitiful! We are both people who have been eliminated by the times, trapped in the gap of time, decaying and dying bit by bit."

Hearing what Luo Ji said, Zhang Xiang laughed.

"Teacher Luo, you are the one who is miserable. I am not imprisoned. I can enter and leave the deterrence center at will. By the way, I also went to eat Chongqing hot pot this morning. You know what, it was really delicious, especially the blood clots that were put into the cold pot and the tripe that was cooked in seven seconds. It was so delicious!"

"Also, Mr. Luo, let me teach you a trick. When you go to eat, don't look for those big stores. Hot pot is only delicious in those small restaurants in corners. Those big stores are just trying to trick outsiders."

Luo Ji took a deep breath and suppressed the urge to press the switch directly.

"Thank you, Zhang Xiang. Next time you tell me this technique, I won't mind letting you clean toilets for a month."

Although he knew that Zhang Xiang's starting point was good, please don't do it next time.

The last time Luo Ji left the deterrence center was more than ten years ago. The Ground Alliance transferred him from one deterrence center to another new deterrence center. During this period, he only saw the scenery outside the window in the car.

More than eighty years of sword-wielding career has transformed Luo Ji from a cynical academic fraudster into a guardian of civilization.

Although his body was still young, Luo Ji's soul had long since died.

Over the past eighty years, he began to speak less and less. If it weren't for Zhang Xiang who would bother him every week, Luo Ji felt that his language skills would degenerate sooner or later.

The only thing he could do every day was to face the wall and repeat his short and ridiculous life over and over again.

The outside world believes that as the Sword Wielder, the pinnacle of human civilization, possessing the power to control both worlds, Luo Ji should be very happy.

After all, he is no different from the ancient emperors.

But only Luo Ji himself knows that his current life is even worse than that of a prisoner in prison.

At least when you are in prison, you know when you will be released or when you will be executed.

But Luo Ji couldn't even die.

He didn't know how long he would stay here.

How long will I be trapped here?

The huge mountain of "responsibility" weighed on him so much that he felt it was difficult to breathe and he could hardly catch his breath.

When he first became the Swordholder, he was very excited and full of confidence in the future.

But as time went on, Luo Ji became more taciturn and his temper became more and more irritable.

At that moment, he suddenly realized that perhaps he had really been tricked by this guy Lin Xuan, and the job of a swordsman was not something a human should do.

Later on, he gradually became relieved. He started to daydream, read books, learn about the changes in the outside world, and gradually adapted to this boring life.

In the end, Luo Ji now feels that he has transcended the scope of human beings.

He felt his soul drifting outside the century, outside the deterrence center, outside the earth, outside the solar system...

The staff thought he had a mental problem at the time and reported the matter to Lin Xuan, who simply said that Luo Ji could take a few days off to rest.

Then Lin Xuan personally came to serve as the sword bearer for a few days.

Luo Ji thought he could have a good rest for a few days, but he was away from the radio switch for less than three hours before he returned again.

That's right, after he left the deterrence center, he inexplicably began to feel a little panic and uneasiness.

Even though he knew that the person who now controlled the transmitter was Lin Xuan, and that he was even more threatening to the Three Body than himself, Luo Ji still felt extremely uneasy, as if he always felt that something was missing from him.

Lin Xuan joked that he had the "occupational disease of a sword wielder" and returned the switch to Luo Ji. Only then did he feel much better.

He has become one with the identity of the Sword Bearer and cannot separate himself from it.

Just like his daughter Luo Congmin.

If you ask her to resign from the presidency now, even if Luo Congmin can get used to it, the top leaders of the Local Federation will not get used to it.

So, Luo Ji returned to his simple and boring life, facing a white wall, and continued to think about his life.

There was a small incident during this period.

About a month or two ago, Ding Yi came to see Luo Ji once to ask about his wife Yang Dong.

Luo Ji was very surprised at the time, because Ding Yi was... well, he only cared about his own physics.

He had built a model of Yang Dong when the Mewtwo world was first established, but at that time he just wanted to focus on research.

And now that Ye Wenjie's daughter Yang Dong was mentioned again, Luo Ji was having trouble figuring out what this devilish old man was thinking.

"The antimatter energy source is almost complete. Bi Yunfeng and Cao Bin's solar accelerator was very successful, and the construction of the ring world has been put on the agenda."

"So, I want to research the next energy direction as soon as possible - vacuum zero-point energy."

Ding Yi raised his glasses and said.

"I haven't figured out how to conduct the specific research yet. I don't even know if this energy source really exists, but I think it has a high probability of existing. It's a pity that Taylor's wall-facing plan was broken by Lin Xuan, otherwise the quantum ghost plan could actually verify this conjecture."

"So, you want to get inspiration from Yang Dong?"

"Yes, she sees things more clearly than I do on many issues. That was true before, but I'm not sure now. I have been working hard to restore her model, not only to commemorate her, but more to dig out from her the relevant experiments she participated in before she died."

Ding Yi said as he pulled up a document.

"To do this, I have to analyze her first. I can't do it by myself. As her former classmate, you may know something."

Luo Ji burst out laughing.

"You must be kidding. Ye Wenjie knows very little about her daughter. What clues do you expect me to give you?"

"Just give it a try. I even found Wang Miao, let alone you."

Chapter 173: The Team is Difficult to Lead

The completion of the construction of the Heliocentric Accelerator indirectly confirmed Luo Congmin's previous conjecture.

The technology provided by the Trisolarans is fake and even full of loopholes.

Except for the three technologies that Lin Xuan wanted eighty years ago, the Trisolarans concealed the rest of the technologies.

This was not surprising to the officials of the Ground Union. After all, when they used the Mewtwo database to reverse engineer these technologies, they found that there were big problems with the parameters. Now, these conjectures have been confirmed.

China has suffered losses in this regard before, so it is naturally impossible to pin all its scientific research efforts on the Trisolarans.

Therefore, most of the technologies shared with them by the Trisolarans were only used as a reference and should not be taken seriously.

This can also be considered a credit to Lin Xuan. The third-phase Super Dream Database has indeed enriched human biodiversity and caused all kinds of strange problems to emerge one after another.

But it is precisely this spirit of questioning that has prevented human scientific development from falling into a dead end from the very beginning.

With the circumsolar accelerator, antimatter energy has been put on the agenda.

The speed of the human fleet has been improved again, and the fastest speed can reach 70% of the speed of light, which is close to the speed of light. If you don’t consider the issue of burning money, it only takes about a hundred years to accelerate to this level with full fuel.

So now the direction of ship upgrades is very clear.

The first priority is still the upgrade of weapons and defensive means. After all, you build these things to fight wars. No matter how much you say, if the fleet weapons are not upgraded, it is just a toothless tiger.

Humans once imagined whether to use antimatter energy as the main attack method of ship main guns, but Ding Yi ridiculed this idea for a long time in an article published in an academic journal.

"Humans discovered that fire can cook food, and then tried to use sparks to burn elephants to death. What era is this? Some people's scientific thinking is still so narrow and limited."

Then Ding Yi threw out a design plan to annihilate the main gun.

This main gun is different from traditional kinetic weapons and electromagnetic weapons, but it is also different from energy weapons.

Through the annihilation effect of matter and antimatter, it can kill any enemy warship that is scratched by this main gun.

There is no need to continuously output damage to the target, just simply touching it will cause the annihilation effect to destroy the opponent bit by bit, which can be said to be an armor-piercing artifact.

At least with humanity's current means of defense, whether it's composite materials or energy shields, they can be easily broken when encountering this thing. Even Sophon said that if the Trisolaran First Fleet encountered this kind of weapon, it would almost certainly be killed.

Actually, there are three Tomoko in total.

But their functions are not the same, which was designed by the Trisolarans from the beginning.

The original second-generation Tomoko, after completing the blockade on Lin Xuan, was also trapped in the force field.

Therefore, the Trisolarans had prepared two more sophons long before they made their plans to fill the vacancy left by the original sophon.

The other two Zhizi, one has the ability to disguise himself, and he is the guy Lin Xuan met before who can change his appearance at will.

The other one possesses a terrifying fighting power comparable to that of an army.

Everyone knows that Tomoko is not good at fighting.

After all, her function is limited to that of a spy, at least that's the case with the original Tomoko.

But the two extra sophons are different.

Disguise Chieko's true image, which no one has ever seen, she can change into the facial features of anyone in the database and imitate their voices.

The combat Tomoko is a woman dressed in a black combat uniform.

The Trisolarans had a complete set of endoskeleton armor embedded in her body. The material was so hard that it could withstand the bombardment of a nuclear bomb.

Because of Lin Xuan's existence, the Trisolarans could not allow the combat Sophon to carry too many weapons into the earth, so she, like the original Sophon, only had a black high-frequency cutting sword on her back.

Now, one of the sophistry has successfully restrained Lin Xuan, and the remaining two sophistry naturally began to act.

"Special Forces Team Zero, reporting to you!"

The combat sophon, dressed in a black combat uniform, saluted slightly to the officer in front of her. The moment she saw the person in front of her, she simulated and analyzed hundreds of human expressions, and selected the most appropriate expression to display on her own face.

"Very good. Your physical fitness indicators during your time in the army were quite excellent. From today on, you will be a special operations member of the Deterrence Center."

The officer looked at the woman in front of him and made a few casual remarks.

People like them who are able to become members of the task force will all have a bright future. In addition, Zero seems to be highly appreciated by the top management, so his future prospects are limitless.

Since the beginning of the Deterrence Era, traditional warfare has been replaced by technology.

The direct impact of this was that a large number of women began serving in the military.

In the past, the military was mostly composed of men because men were physically better suited to fighting than women.

However, since the establishment of the Space Force, more and more people have discovered that the advantages in biological physical fitness have been eroded by the rapid development of technological equipment, so men and women have equal rights to join the military.

This can actually be seen from the composition of Fleet International.

One third of the fleet members who participated in the escape with Zhang Beihai were women.

Women having equal rights to join the military is an inevitable trend in future technological wars.

In order to protect the Sword Bearer Luo Ji, the Ground Alliance formed a task force and recruited elite troops from various units in an attempt to establish a defense force led by Zhang Xiang around the deterrence center.

And the combat sophon, or should she be called Zero on the human side.

Her performance was outstanding.

During his five years in the army, Zero has performed quite well in physical training, fighting skills, and even mecha control.

"Isn't it outstanding? Damn, a human disguised as an artificial intelligence has an IQ and combat capability that is at least several levels higher than that of ordinary humans!"

As for the political background, according to the information.

Zero's parents were space soldiers in the Doomsday War, and his grandfather was a rebel who assisted Lin Xuan in defeating the PDC.

Zero’s political background is much more perfect than imagined, so perfect that it seems unreal, as if someone has hacked into the system and tampered with her resume.

The top military brass had never seen anyone with such a strong political background.
