After leaving the library, Chen Zhou and Yang Yiyi walked back to the dormitory.

When the two of them walked to Wuming Lake, they stopped unconsciously.

Under the lights, Wuming Lake has a unique view.

Chen Zhou turned his head and looked at Yang Yiyi and said softly: "Yiyi, let's walk along Wuming Lake for a while?"

Yang Yiyi nodded: "Okay."

Chen Zhou took Yang Yiyi's hand, and the two of them walked quietly by the Wuming Lake.

Objectively speaking, Yan University is not only a top university in China, but also one of the most beautiful universities in China.

After all, there are many antique buildings on the Yan University campus, and they also have certain historical significance.

Take Yanyuan as an example. It was originally a Shaoyuan in the Ming Dynasty and later a royal garden in the Qing Dynasty.

Now it has become the Yan University campus.

The most famous thing about Yanda is the Wuming Lake where Chen Zhou and the others are currently strolling.

It is known as "Yitahutu" together with Yabota and Yanda Library.

If the lotus flowers bloom, the entire lakeside of Wuming is filled with fragrance.

In addition, the Yabo Tower on the shore is towering into the clouds and standing tall, as if guarding the mountains and rivers.

The movement of Wuming Lake is matched with the tranquility of Yabo Tower, the movement of the lake is quiet, the soft and the tower is strong, and the tower and the lake complement each other.

Chen Zhou pointed to Yabota in the distance and asked softly: "Yiyi, do you know what this Yabota originally did?"

Yang Yiyi glanced at the Yabo Tower, which imitated the ancient tower of Lanting, and said with a smile: "Of course I know, it was originally used as a water supply tower."

Chen Zhou nodded slightly and asked again: "Do you know the meaning of Yabota and Wuming Lake?"

Yang Yiyi thought for a while and replied: "Yabota means Boya. If Wuming Lake is the case, I won't know."

Chen Zhou stopped, looked at Yabota in the distance, and said slowly: "In front of Yabota, I sought Boya, and I swear to be famous by the Wuming Lake. Their meaning is to swear to become a Boya person in Wuming Lake."

Yang Yiyi looked at Chen Zhou with a smile: "Okay, okay, I know you are a master of Chinese literature."

"Hehe." Chen Zhou smiled embarrassedly.

Yang Yiyi glanced at Chen Zhou and asked softly: "Do you have any worries?"

Chen Zhou shook his head, nodded again, but said nothing.

Seeing this, Yang Yiyi said softly: "What's the subject?"

"Yes." Chen Zhou nodded, "Today, Professor Zhang taught a math game in the small class, which is an inspiring class."

Yang Yiyi asked: "What game?"

Chen Zhou: "Hail conjecture."

As smart as Yang Yiyi, she naturally understood what Chen Zhou meant.

She thought for a while and said, "It's really difficult to study this as a subject. But if you decide it, why would you hesitate?"

Chen Zhou turned his head and looked at Yang Yiyi. He was indeed hesitant.

Although I made the decision to study the hail conjecture, I also set a deadline for myself.

However, he was still a little worried about this global problem.

The most fear is that I spend time but get nothing.

Chen Zhou admitted frankly: "I don't know if I can complete this project."

Yang Yiyi held Chen Zhou's hand tightly and said softly: "If you hesitate like this, you won't be like you. The one who dared to make an agreement with all the teachers and students in the school, and plans to complete the Department of Mathematics and Physics in her freshman year.

People who graduate from the double should be someone who will never hesitate when encountering anything."

"We don't know what the future is like, but we can take every step of today for the sake of the future. And the result of this topic should only be known after we have done it."

"The most important thing is that I believe your decision."

This was the first time Chen Zhou heard Yang Yiyi say so much. What he saw from Yang Yiyi's eyes was full of belief.

Chen Zhou smiled gently and rubbed Yang Yiyi's head with his other hand: "You are right, you should have known it after doing it. Instead of hesitating after you have made a decision."

"Yes." Yang Yiyi said with a smile, "Isn't it just like you said, asking for Boya in front of Yabota, and swearing to be famous by the Wuming Lake, why don't we just..."

Before Yang Yiyi could finish her words, Chen Zhou suddenly used force in his hand and pulled her into his arms.

He hugged him very tightly.

Her hands were also panicked from the beginning, and then slowly put on his body.

Chen Zhou said softly in Yang Yiyi's ear: "Thank you, Yiyi, it's great to have you."

Although Yang Yiyi didn't speak, she smiled unconsciously.

It took a long time before the two separated.

Chen Zhou looked at Yang Yiyi's red face and couldn't help but quip: "Did you become a Red Apple?"

"Hmph." Yang Yiyi snorted, "You are the Red Apple."

When Chen Zhou returned to the dormitory, it was almost 11 o'clock, which was much longer than usual when he came back from the library.

As soon as they entered the dormitory, Zhao Qiqi and the other two looked at Chen Zhou together.

Chen Zhou asked in confusion: "Why are you looking at me like this?"

The three of them said in unison: "It's nothing, I thought you wouldn't come back tonight."

Chen Zhou was slightly embarrassed: "If I don't come back, where will I sleep?"

Zhao Qiqi said, "I don't know."

After a pause, Zhao Qiqi discovered something keenly, and then said softly: "You have the smell of her perfume on you, it's my nose that I have committed a crime..."

Chen Zhou: “…”

Zhu Mingli and Li Li laughed secretly.

Neglecting these three people, Chen Zhou picked up the basin and went to wash.

"Damn..."

When washing up, Chen Zhou realized why these three people looked at him like this.

When he hugged Yang Yiyi, Yang Yiyi's hair fell on his clothes.

Still a very conspicuous position...

At night, Chen Zhou, who was lying on the bed, remembered Yang Yiyi's words, and there was a smile on his lips.

Chen Zhou's heart became more eager to solve the problem of hail speculation.

After sending Yang Yiyi a [Good Night], Chen Zhou fell asleep.

In the next few days, Chen Zhou studied the physics teaching materials according to the plan.

On the one hand, spend a lot of time on looking up related issues of hail conjecture.

There was one unexpected discovery to him, that was the algebra discussion class about Zhang Zhongyuan.

Some of the content discussed in the class were recorded in the wrong questions.

This also verifies from the indirection that the class is flawed.

Those who have not been recorded also provide Chen Zhou with some references to the topic.

"Forming the problem is something that must be done to solve the conjecture. Regarding the hail conjecture, or the 3x1 conjecture, his formula is an iterative formula, with input, output, and feedback..."

Chen Zhou first formulated the hail conjecture and then studied it.

【xn1=(3xn1)/2^m, in the formula, each x is an odd number, m=1,2,3…】

[Until the even number 2^m in 3x1 is precipitated and canceled, so that the right side of the equation is an odd number. If this odd number is not 1, but other odd numbers, continue iterating until 1.]
