After Li Yang had dinner, Li Yang rested.

Li Yang woke up again, it was 8 o'clock the next morning, got dressed, packed the necessary things, took the car keys, and went downstairs to drive, heading to Yang Dong's laboratory.

His driver's license was taken by him in the summer vacation after the college entrance examination, and his father did not buy him a car, but now he drives his father's car, which can be said to be a trick.

When the car drove in the morning rush hour on the North Star, when Li Yang drove the car that his father had driven before his death, it seemed that his father was everywhere in the car, maybe the memory in his mind didn't want him to forget his father.

Li Yang, who was driving the car, was not in a high mood, but when the car arrived at its destination. Before 12 noon, according to the address given by Luo Ji, Li Yang found the address of the laboratory where Yang Dong worked.

Outside the laboratory, Li Yang took out his mobile phone after parking the car and dialed Yang Dong's work phone, his mobile phone was Motorola V3, which his father bought for him before his death, which can be regarded as a birthday gift for Li Yang.

After the phone rang a few times, a crisp voice rang in Li Yang's ears, "Hey, hello, who are you?" What's the matter with you? The other end of the line said.

Hearing the voice on the other side of the phone, Li Yang hurriedly said, "Professor Yang, hello, my name is Li Yang, and I am the son of your colleague Li Ziyan." My father, before he died, left me a letter in which he said that you are a good scientist and he asked me, if I am in trouble, to come to you.

At the same time, I am also a student in the Department of Sociology of North Star University, my teacher Luo Ji, gave me your contact information and address, he asked me to communicate with you if I have questions about the three-body game, I don't know if you have time, it just so happens that I do have some questions now, I hope to get answers from you. ”

There was silence on the other side of the phone for a while, and then Yang Dong said: "Hello Li Yang, since your father and Luo Ji asked you to come to me, and you also have questions, then you can come." I'm in the lab right now, and you have the address, so I have time this afternoon so I can answer your questions. When you get to the door, send me a message and I'll ask the doorman to take you in and go to my office and I'll talk to you. ”

After Yang Dong finished speaking, he hung up the phone, Li Yang listened to the sound of the phone on the phone, smiled, then put down the phone, put down the driver's seat, closed his eyes and rested, he planned to go to Yang Dong later.

About half an hour later, Li Yang sent a message to Yang Dong, saying that he had arrived and that he was going up. Then Li Yang walked out of the car, locked the car door and walked to the doorman, found the security guard on duty at the time and told him that he had made an appointment with Yang Dong.

Later, under the leadership of the security guard, Li Yang followed the security guard to Yang Dong's office, and when he arrived at the office, the security guard left, and when he saw that there was no one in the office, Li Yang waited for Yang Dong's arrival at the door of the office.

Li Yang waited at the door of Yang Dong's office for less than five minutes, and saw an intellectual, mature woman in a white coat walking towards the office at the top of the stairs.

Li Yang thought to himself, she is Yang Dong, he is the white moonlight that haunts Luo Ji's dreams, and it is also Luo Ji's youthful regret.

When Yang Dong walked in front of Li Yang's body, he said, "Hello, you are Li Yang, I'm Yang Dong, your father's colleague, let's go in and talk if you have any questions." Then he walked into the office.

Li Yang replied, "Yes, Professor Yang, hello, I'm Li Yang." As she spoke, she followed Yang Dong into her office.

As the master, Yang Dong gestured to Li Yang with his right hand and said, "Please take a seat."

Then he sat down at his desk, Yang Dong said, "I have a good relationship with your father, the two of us are also teachers and friends, after I entered this scientific research institute, he is my guide in astrophysics, although I mainly focus on the field of basic physics, but he still has a great influence on me."

But the other day, I was at a loss when I heard the news of his suicide, and he committed suicide because the basic astrophysical rules saw no hope for research, how similar to me, and now I am in a cage.

I don't know what exactly you're here to ask today, but I'm willing to answer everything I know, just because you're the son of Li Ziyan. After speaking, Yang Dong stared at Li Yang.

Li Yang also looked at Yang Dong's eyes, looked at her, and said at the same time: "Professor Yang, I listened to what you just said, and what I said in the suicide note that my father left for me before his death, makes me feel that the basic scientific research of Blue Star is hopeless, why is this?"

Could it be that you great scientists have reached the end of these cutting-edge theoretical disciplines such as basic physics? I always felt something was wrong, but I couldn't tell what was wrong.

And I heard the three-body game from Mr. Luo Ji, I heard that you told him, although I have not played the three-body game, but listening to Mr. Luo's narration, I have a big question, no game company can make such a realistic game, the current technology is impossible to complete.

Therefore, I feel that the three-body problem really exists, and I do not rule out this statement, because it is difficult for me to imagine that my father, as a staunch materialist, as a scientific researcher engaged in astrophysics research, would commit suicide because there is no hope for research, which is one thing that I can't figure out.

So I came to you, Professor Yang, to clear the doubts in my heart, and at the same time, I feel that if the Three-Body World really exists, and if a civilization is found that is even lower than the Three-Body Civilization, then they will definitely not give up.

Even I don't rule out that there are civilizations like the Three-Body Problem that maliciously block the technological development of Blue Star. ”

Yang Dong smiled and said, "Your idea is a bit sci-fi, if there are really external forces that interfere with the development of Blue Star's basic science and technology, then how powerful such a civilization must be."

The reason why I told Luo Ji about the Three-Body Problem Game was to let him wake up from his depravity as soon as possible, and I hoped that the cyclic suffering of the Three-Body Civilization in the Three-Body Problem Game would not defeat their spirit and allow him to learn, not that the Three-Body Problem Civilization really exists.

In my opinion, it was just a game, and as for what you said about someone who caused your father's suicide, I think this matter should be referred to the relevant authorities for investigation. As for the lack of progress in my basic scientific research work, I think I should take another look, scientific research itself is not an easy road, and maybe new discoveries will be made soon.

Child, wait and see, don't rush it, you have to know that when something happens, it's actually been brewing for a long, long time before it happens.

If the result can't be changed, then just change the process, and I hope you can study hard, even if you study sociology, I think you can make a difference to this society.

Strive to become a scientific researcher like your father, sociology is also a science, worthy of your study, Luo Ji is also a good teacher, although life is informal.
