After the wheat fields in North America initially helped relieve Wang Miao and Ding Yi's confusion about the future, Li Yang and Wang Miao returned to Northern Star under the protection of Shi Qiang.

After arriving at the Northern Star, Li Yang went home to rest for a few days, and then went to school to find Luo Ji. He had not gone to see him before because of the International Federation Conference. Now Li Yang wondered whether Luo Ji had communicated with Ye Wenjie. Ye Wenjie

Have you taught him those two axioms?

Li Yang chose Wednesday afternoon. Luo Ji happened to have a sociology class on that day, so Li Yang chose to go directly to the classroom to find him. After all, he was also a student at Northern Star University and had some connections with the military and the police, so he knew what to do.

The location of Luo Ji.

Sitting in the audience and looking at Luo Ji, who was still talking eloquently, Li Yang couldn't help but think of the scene when he had just returned from time travel. It was also in Luo Ji's class, but who knew that in less than a year, what happened

There have been so many changes.

Indeed, Luo Ji's handsome appearance attracted Li Yang, who was looking at him at this moment, "Maybe he is the only one who hasn't changed much!"

Luo Ji, who was giving a lecture on sociology on the podium, also saw the student sitting in the back row, the student who had contact with Yang Dong, the student who he personally gave him Yang Dong's contact information, the one who could be said to be the one between him and Yang Dong.

Luo Ji was the last student he contacted. Luo Ji had a deep impression on him. He still remembers him as Li Yang, and he was a sociology student who did well.

The class time passed very quickly, and soon the bell rang. When all the students in the classroom were about to leave, Luo Ji, who was packing his things, looked up and saw that Li Yang hadn't left yet, and was looking at Li Yang with his arms folded.

Looking at myself, I understood that this guy wanted to talk to him.

After Luo Ji packed up his things, he walked off the podium with his backpack and walked towards where Li Yang was sitting, saying as he walked:

"Long time no see. I see you haven't left even after class. Do you still have any questions to ask me?"

Seeing Luo Ji walking up, Li Yang, who was sitting at the back of the lecture theater, also stood up, "I don't want to ask you a question, I just want to have a chat with you, Professor Luo."

"Let's talk? What should we talk about? How about we go out and talk while we walk?" Luo Ji stood next to Li Yang's chair and motioned for Li Yang to go out for a walk.

"Okay, I can do that. Then, Professor Luo, let's go for a walk."

"Okay!" So Luo Ji took the lead and walked around in the garden of North Star University with Li Yang.

"It's been half a year since we first had a heart-to-heart talk. A lot of things have happened in the past six months. Yang Dong, whom I introduced to you, has passed away. Do you know this?"

"Professor Luo, I know what you said about Professor Yang's death. I not only know about Professor Yang's death, I also know why she died. I even know who is the mastermind behind this.

I have experienced a lot in the past six months, and I am even dissatisfied with you for saying that I have experienced life and death. After experiencing so much, I want to come back and talk to you again.

Confucius said, "Three people walking together must learn from each other. You, as the astronomer and sociologist our country has contact with, I can gain a lot from chatting with you, so I came to you."

"It's hard for me to imagine that a college student can say such words as having experienced life and death. I don't know what you have experienced, but I think I can be a listener and answer some questions that I know."

"Teacher Luo, I can take the liberty to ask, what is the relationship between you and Professor Yang Dong? It should not be a simple relationship between high school classmates."

"Me and her, to be honest, I liked her in high school. She was the goddess in my heart at that time or she is still now, but it's a pity that she and I can't get together. Personality determines everything.

But I don’t regret it, because compared to her, I am a waste, I am not as pure as her, and I am not worthy of her. Now that she is gone, I think she has gone there to pursue her dream of physics.”

"Teacher Luo, maybe there is just a little bit of fate between you. It's a pity. It's such a pity for you. By the way, have you seen the mother of Teacher Luo and Professor Yang? Just recently."

"You are talking about Professor Ye Wenjie, right? I met her when I went to Yang Dong's grave some time ago. She was not in a good condition at the time. You ask me, what happened?"

"Oh, Professor Ye passed away and was buried next to Professor Yang Dong. If you want to visit them in the future, you can buy a bouquet of flowers for Professor Ye.

Moreover, I am currently studying something about the universe, and I know that Professor Ye is also an astronomer. I wonder if she told you anything about the universe and astronomy when you two met."

"You said that Professor Ye passed away. I didn't expect her to die so soon. Maybe it was because of the death of her daughter. As for your question, did she tell me anything about cosmology and astronomy? Yes, she did.

When I met Teacher Ye in front of Yang Dong’s tomb, she told me that she wanted me to create a subject called cosmic sociology, which assumes that there are thousands of planets with civilizations in the universe, and that there are connections between these civilizations.

What kind of relationship, what kind of communication relationship, Professor Ye wants me to study this, that is, to study the sociology of the universe.

In fact, in my opinion, there is a big difference between cosmic sociology and human sociology. The key to human sociology is actually to study social problems and solve problems, while cosmic sociology is because I don’t know if there is such a civilization at present, and I don’t know.

What kind of civilization exists in the universe?

I don’t even know if some kind of civilization exists in the universe, whether it is carbon-based organisms, silicon-based organisms, or other organisms. We don’t know what their thinking mode is, we don’t know everything, we only know where we are.

So in my current opinion, this sociology of the universe is quite difficult, but Professor Ye told me two axioms, which I think are very reasonable. First, survival is the first need of civilization; second, civilization continues to grow.

and expansion, but the total amount of matter in the universe remains the same.

There are even two key words, chain of suspicion and technology explosion. These are what Professor Ye told me. I have thought about it a lot these days, but I haven’t figured out the reason yet. I hope these can be helpful to you.

"

"Okay, thank you, Teacher Luo. I have chatted with you for so long and learned a lot. Thank you.

By the way, Teacher Luo, you should have read the news. The Three-Body Problem really exists, which means that the sociology of the universe is worth pondering. I also suggest that you create the discipline of sociology of the universe.

The last piece of advice is to be safe when traveling!”

After saying that, Li Yang looked at Luo Ji deeply, then said goodbye to Luo Ji, turned around and left. Li Yang planned to start the wall-facing plan.
Chapter completed!
