Yang Dong also quickly finished washing up, carried a small suitcase, and went downstairs with Ye Wenjie.

Jiang Yu took the initiative to help her carry her suitcase. After asking, she found out that where Ye Wenjie gave this speech, she wanted to take a ride with her workplace.

A business car has been parked downstairs, and this is the car that came to pick up Ye Wenjie.

Jiang Yu put the box behind and was about to sit in the co-pilot, but found that there was a slim and beautiful girl sitting in the co-pilot.

She was playing with her phone intently, as if she felt Jiang Yu's gaze. She looked up and smiled at Jiang Yu.

This smile is very moving and eye-catching, but for some reason, Jiang Yu felt a little chilled in his heart when he saw it.

"Xiao Yu, come back!" Ye Wenjie greeted.

Jiang Yu nodded and sat behind.

This trip will take more than three hours, and Jiang Yu and the other three sat in the back seat and started chatting.

Sometimes people talk about dialogue, art and physics, and sometimes they talk about the research that Yang Dong is doing.

Yang Dong said that all the particle collision tests recently seemed to have stopped due to unknown reasons. She hoped to use Ye Wenjie's relationship to understand why it stopped?

Ye Wenjie fell into a brief meditation and did not agree to her daughter's request.

Evans concealed the role of Zhizi, which even Ye Wenjie had only a general understanding of Zhizi, but she could guess that the stop of the particle collision test must have something to do with the Three-Body Stars.

Yang Dong did not continue this topic, but judging from her appearance, she should continue to understand this aspect.

In order to change the topic, Ye Wenjie discussed some propositions of sociology with Jiang Yu: "Xiao Yu, since we talked at the dining table last time, I have developed a strong interest in sociology and have been reading this topic recently."

She continued, "Xiaoyu, what do you think civilization is?"

Jiang Yu smiled and said, "Teacher Ye, can I tell you my personal understanding?"

Ye Wenjie was very happy: "It is a basic quality of a scholar without sticking to books. I and Gao Qing can see this quality in you."

"Teacher Ye has been awarded." Jiang Yu said: "I think civilization is survival."

Yang Dong, who was also attracted by this topic, asked, "Survival?"

"Yes, survive." Jiang Yu explained: "All manifestations of civilization are for survival.

"Let me give an example, why did you need to choose a spouse in ancient times, 'the parents' orders, the words of the matchmaker'?"

Jiang Yu asked and answered: "At that time, people at that time found that intimate relatives were prone to problems such as hereditary diseases after long-term observation.

"In order to avoid getting married in close relatives, we cannot fall in love freely, because at that time, everyone's playmates from childhood to adulthood were basically their own brothers and sisters, or close relatives.

"If you start a family through free love, a large number of close relatives will be married. In this case, it will be a question whether the ethnic group can continue.

"Only parents and matchmakers know who are not close relatives, so they have to listen to whom they get married."

Yang Dong smiled and said, "I didn't expect the sociological discussion to be so interesting."

Ye Wenjie also smiled and nodded, looking at Jiang Yu and listening to his explanation.

Jiang Yu smiled and said, "Every discipline has the charm of every discipline. Only by discovering the charm of one's own discipline can one find some tricks."

He continued to explain: "So ancient customs have some truth, but they are not applicable now.

"Now people living in the city live a life of separation from their wives and children, and can have a bold and free relationship, because the probability of getting married in the city is too small.

"But now there are new problems that are in front of free love, such as houses.

"Why do everyone value houses so much? It's just for survival! Come to this world and have no place to stand, and it's nothing to survive.

"Psychologically, having a residence and a way to survive can one be considered as having the illusion of being in the world."

Jiang Yu scratched his head: "If you continue to discuss, you will be elevated to the philosophical level, and the discussion is of little significance.

"As long as everyone understands that all appearances of modern people are also based on survival as the essence, it is just that it is more abstract than before, and most people are more difficult to detect."

Yang Dong nodded: "Your theory makes sense, at least it can explain most of the appearances."

Ye Wenjie smiled and said, "It can even explain some things in astrophysics. After all, the universe is also a large society!"

After saying this, Ye Wenjie suddenly realized that she seemed to have figured out something.

She murmured to herself: "The universe...social...survival..."

Jiang Yu's liver trembled, and he thought to himself: "It was my thought just now that Ye Wenjie had a basic concept of the 'Law of Dark Forest', right?"

It is not impossible for Ye Wenjie to propose the basic concept of "dark forest" to Luo Ji without having any idea of ​​this.

Ye Wenjie had never been exposed to sociology before, and only came into contact with this subject after getting to know him, Jiang Yu.

Jiang Yu immediately realized that he was not "rewriting history" now, but rather, it was like putting "history" back on track.

The topic of sociology continues, and Jiang Yu thought about it casually and then he withdrew his thoughts.

After driving for more than three hours, everyone came to a university in the neighboring province, where Ye Wenjie's first speech place was.

The driver took Yang Dong to the research institute not far from here. Jiang Yu and the girl accompanied Ye Wenjie to chat with the school staff briefly. Ye Wenjie went to the podium and started her speech.

Jiang Yu showed a strong interest in Ye Wenjie's speech. Every time Ye Wenjie turned her attention to Jiang Yu, she saw Jiang Yu listening to his speech with all his heart.

Although the old lady didn't show it on the surface, she was still very happy.

After having lunch prepared by the school, the afternoon was a physics discussion. Jiang Yu and the girl were not qualified to attend, so the two of them were waiting for Ye Wenjie in the seat outside the conference room.

The girl had a moving smile, but didn't say much: "Chu Xu."

"Your name will tell you that you have many passbooks in your hand." Jiang Yu joked.

But the girl did not laugh, Jiang Yu said a little embarrassedly: "Jiang Yu."

Chu Xu took out a box of cigarettes and handed them to Jiang Yu.

Jiang Yu did not refuse, and the atmosphere was already very awkward. If he refused again, it would be even more awkward.

Chu Xu lit the cigarette and glanced at Jiang Yu: "Why don't you advise me: It's better not to smoke a little girl?"

Usually, people who see her smoking for the first time, especially men, will persuade her.

Jiang Yu tasted the long-lost tobacco taste: "My life experience tells me that you should never use the moral high ground to persuade others. The more you persuade them, the more others will be prepared for you."

Chu Xu's eyes suddenly became dim: "If my mother didn't run away with other men, she would definitely let me continue to go to school. If I could go to so much school like you, I would have learned so much in school."
