After Ying Xingchen replied [good night] to Yang Fan, he suddenly remembered Yi Shuyan again. However, she has only been separated from Yi Shuyan for a short time, and he should have slept now, so should she send him a goodnight message?

It used to be sent every day, so let's send it today, so that the team will be neat.

Thinking of this, Ying Xingchen, as usual, whispered a voice message to Yi Shuyan: "Boss, good night." Then he fell asleep.

Yi Shuyan lay quietly on the bed, his hands folded under the back of his head, his eyes looking at the ceiling. He remembered what he had done to the stars tonight, and he couldn't help but blame himself again.

When facing her, he is really unprincipled and undisciplined.

He didn't like himself like this, he was annoyed by her words, and he rejoiced because of her words. He became moody, his emotions were touched by her smile, and things were completely out of his control.

Tonight, he couldn't help but do such a thing to her while she was unconscious. Is this still him? What a difference this is from a hooligan! After going downstairs to buy medicine to calm down, he planned to be cold to her from now on, but as soon as he saw her pitiful appearance, he immediately couldn't help but treat her well, is his restraint and willpower just decorations? How did they become so weak?

can't indulge herself like this anymore, just take advantage of her military training to adjust her mentality.

Suddenly, Yi Shuyan received a voice message saying good night from Ying Xingchen. He didn't reply to her, just put on headphones and listened over and over again until finally, inadvertently falling asleep.

The golden autumn sunshine and the cool breeze fell on the campus, making this morning both charming and comfortable.

Ying Xingchen woke up early in the morning and received a message from Yang Fan [Get up, little star]

She was overjoyed in her heart and replied [You have to perform today, come on!] 】

She felt that she was in good shape today, so she didn't ask for leave, after breakfast, she took the medicine that Yi Shuyan bought for her, and then went to the square with everyone to train.

After Yang Fan saw Ying Xingchen's message, he was also very happy in his heart, and he replied to her [Well, you also have a good military training today, and I will look for you tonight. 】

After the show, there was another party, and after the party, the military training officially ended.

Yang Fan stayed in the library on Saturdays and Sundays to read textbooks, in other words, he must have gone to the library with Ying Xingchen to study, but now that she is far away, he can't help but feel a little lost. But he knew that Ying Xingchen was still training at this time, so he didn't bother her, and he himself quickly immersed himself in the scientific world described in the book.

On Monday, Yang Fan finally met Zhou Xuechen, a quantum mechanics teacher who is one of the three crazy people at HKUST.

Zhou Xuechen is a classroom teacher and has his own laboratory at the university to specialize in quantum mechanics. He is a scientific maniac, an authority on the academic world, and at the same time a maverick, a maverick, unreasonable and unreasonable physicist.

He's still unmarried, because he's always forgetting that he's dating a girl or that he's dating a girl in order to solve a physics problem that pops up in his head.

Yang Fan listened to his lecture very carefully, and after listening, he only had one feeling, all the cells in his body were surging, and he couldn't wait to explore this world of quantum mechanics more deeply.

He was eager to share his feelings with Ying Xingchen, and he was used to sharing everything about him with her. [Xingchen, I took a class on quantum mechanics today. 】

Ying Xingchen, who was sitting at the desk in the bedroom and doing nothing, quickly replied to him, [How do you feel?] 】

[I'm very happy, excited, and want to learn more.] 】

Seeing Yang Fan say this, Ying Xingchen was also very happy for him, and replied [Well, classmate Xiaofan, come on!] 】

As soon as the message was sent, Yang Fan called. Ying Xingchen took his mobile phone and walked to the corridor outside the dormitory to chat with Yang Fan.

Yang Fan excitedly talked to her about the knowledge he learned about quantum mechanics today and his own opinions and understandings, and Ying Xingchen listened quietly with a smile on his face as before, occasionally interjecting two sentences and asking two questions. Although the two of them could not meet, everything seemed to be back to the way it was, and their hearts were full of joy.

After a long time, the phone call finally ended, and the two reluctantly said goodnight, and then hung up the phone.

Ying Xingchen held on to the guardrail, looked at the night view of the campus, took a deep breath, and when her eyes touched the warm yellow street lamp, she suddenly remembered Yi Shuyan.

Yi Shuyan didn't pass by the square today, and he didn't send her any message. In fact, this is not surprising, because she had told him not to disturb her during her military training. Moreover, now that he knew that she was sick, he would not do anything to her.

Ying Xingchen clicked on WeChat and sent a message to Yi Shuyan in a task-style manner: "Good night." Then he went into the dormitory, washed up, and got ready for bed.

Before Ying Xingchen went to bed, he looked at WeChat and found that Yi Shuyan had not replied to her, and he couldn't help but wonder a little in his heart. He will reply to her on weekdays, and a casual reply with the word "um" is also a reply. He didn't reply yesterday or today, making me feel like I was talking to myself and singing a one-man show, when did the boss become so rude? Belch...... Could it be that he was infected by me, also caught a cold, and was recuperating, so he didn't even look at his phone.

Don't guess, maybe he's just busy, he also said before that he has a lot of subjects to repeat, maybe he's studying hard! Leave him alone, anyway, tell him good night just to complete the task, just do it.

Ying Xingchen sighed, and then fell asleep.

Yi Shuyan squinted at the phone with cold eyes, and his fingers couldn't help but move over and click on WeChat, and then click on Ying Xingchen's voice message to listen. He suppressed the joy in his heart, quit WeChat expressionlessly, and continued to read.

Zhou Xuechen gently closed the door of the research room and returned to the faculty dormitory alone. He was in a particularly happy mood today, and that joy came from one of his students.

More than half a year ago, Zhou Xuechen saw an article on quantum mechanics in a physics journal, and he saw the author's understanding of this field, his deep insight into physics, his rich imagination, his excellent mathematical derivation ability, his grasp of language, his systematic expression, etc., all of which surprised Zhou Xuechen.

And the author's name is also deeply imprinted in his mind - Yang Fan. He expected that Yang Fan must be an old scientist who had studied quantum mechanics for many years, but he wondered why he had only seen his published article for the first time now.
