We are all reborn, who will be your control group?

Chen Xiang rolled her eyes at the three of them and just left.

Shang Daqing was a little embarrassed: "Chen Xiang has a problem with the two of us, I don't want to implicate you."

Wen Qin originally wanted to ask why, but there were so many people walking around, and it was not appropriate for the three of them to keep talking like this, so she could only smile and say it was okay, then started to concentrate on her work.

Although the alley is long, it is relatively narrow, so the three of them can work very quickly with this division of labor. Some old men and women see how busy they are and bring water out of their houses for them.

Wen Qin was wearing too many clothes and sweated a lot after exercising. When she saw that the snow had been cleared, she hurried home to change clothes.

It’s too cold and there’s not enough hot water at home. I don’t dare take a shower now and can only wipe myself twice.

After a whole morning of such fun, she lost interest in playing in the snow anymore.

The door, which was usually left unopened, was knocked again, and Shang Daqing came over to return the candle.

"Thank you for the candle."

"No need to thank me. Everyone has times when they don't have what they need. If I were to borrow something from you, wouldn't you lend it to me?" After working together for a while, they became familiar with each other, and Wen Qin spoke more casually to Shang Daqing.

"My mother said that you are home alone and probably haven't cooked yet. Why don't you come to my house for a meal?" Shang Daqing took a look inside and confirmed that Wen Qin had not started the fire to cook lunch, so he quickly invited her.

Wen Qin was just about to boil water to cook instant noodles, but she didn't expect someone to be willing to let her eat for free.

But Wen Qin knew how important food was right now, and felt a little embarrassed to ask for someone else's food, so she refused: "No, no, I made noodles. If you don't eat it, it will get mushy."

Seeing Wen Qin insisted, Shang Daqing said nothing more and went back.

Faintly in the next room I could hear his mother scolding him for not calling the person back.

Wen Qin felt somewhat heartwarming.

Have you confined yourself to a small circle? Should you go out for a walk?

Wen Qin ate two large bags of instant noodles while they were still hot, and took a long breath. She remembered that it was inconvenient for the elderly to take care of the elderly on a snowy day, and then she thought of Teacher He. Since it was her good friend who had entrusted her with the task, she always had to pay more attention to it.

The wontons she had made earlier could be frozen outside if it was cold today. She took a lunch box and packed some.

Because she didn't know whether other neighborhood committees had shoveled snow and because the roads were slippery, Wen Qin didn't dare ride her bike. She just picked up a bag and walked to Teacher He's house.

When I arrived at the place, I was surprised to find that the professor was also there.

This was awkward. Looking at the bag in Wen Qin's hand, the professor pointed at her and said to Mr. He, "See, my student has never sent me food, but he has come to you twice."

On the table were the snacks that Wen Qin brought yesterday.

These words were so hurtful that even though Wen Qin had become thick-skinned, he still felt embarrassed.

"Professor, what you said is wrong. I wanted to give it to you, but you didn't give me the chance." Wen Qin said this with a straightened back. Yes, she didn't even know where the professor lived, so how could she have the chance to give it to you.

The professor just looked at Wen Qin. When he saw Wen Qin lower her head, he slowly spoke: "As for me, I live in the school dormitory."

Wen Qin felt her back getting wet again. This professor seemed to dislike her recently.

"I'll cook wontons for the two teachers. I made them myself." Wen Qin quickly picked up the box of wontons and ran away.

When Mr. He saw Wen Qin running away, he smiled and shook his head, "This kid is pretty good. Why scare her like this?"

The professor reached out and poured a glass of water for Mr. He: "This child... is hard to say."

Mr. He was a little surprised: "Why? Although I only spent one day with her, she was concerned about someone like me just because of a classmate's request. I think she is a good person."

The professor put down the teapot in his hand and said, "I borrowed a book from her."

Mr. He was a little surprised: "You old man, you can borrow books from anywhere. You are so shameless to borrow books from students."

The professor simply said the title of the book, and successfully changed Mr. He's expression.

"I remember there was only one copy of this book in the school library, right?"

Because this set of books was unpopular, not many copies were published, and many of them were destroyed by ignorant men and women. Apart from the collections in a few major universities, there are not many left outside.

"Does she have a family tradition of learning?" If it was passed down by the elders in the family, it would not be surprising.

"She was the top scorer in the college entrance examination in Jiangcheng County last year. At first, I just knew that she was a student who came from the countryside and passed the exam. Later, she proposed the idea of ​​a microcomputer, and I paid attention to her. I specially wrote a letter to Lao Lu who was sent down to Jiangcheng County at that time." The professor looked at the busy figures outside the room, "Lao Lu's reply was very meaningful."

Mr. He's expression also turned serious: "Is there something wrong with her?"

The professor shook his head. "She was born in poverty for eight generations. She is the youngest in the family. Her eldest sister is a worker, her brother-in-law is also a worker, and she married a worker. Old Lu even revealed a piece of information. She was the key figure in the Shanghai trafficking case that shocked the whole country last year. She was called a heroine and made a report. If she had been recommended to go to college before, she would have been qualified."

Mr. He felt even more confused: "Then there is no problem. Why do you look so wary?"

"Don't you think this is the biggest problem? She not only helped me find the book, as far as I know, any classmate who asked her to find a book, she would find it without exception. It is said that she has a relative who works in the library, but Old Lu said that her family has been poor peasants for eight generations and she has no connections in the imperial capital."

As the professor spoke, he took out a book from his arms. If Wen Qin was there, she would have noticed that it was the book she found for the professor.

The book looked intact, but the words had been torn or worn off in several places, making it look half-old and half-new, and there were even some places that had been splashed with water.

But even so, the professor was still very careful when he took it out and handed it to Mr. He.

After Mr. He took it, doubts grew in his eyes.

"There's something wrong with this layout."

"The layout is clearer now. I remember there was a misprint here, but it has been corrected in this edition."

The professor turned the book to a certain page: "A page has been torn off here."

He Lao stared at the page for a long while before saying, "The title page and the back cover usually have edition numbers and printing times..."

"I compared it with the one at school, and the paper is different."

"Is this book privately printed?" It's not that there are no privately printed books, but if someone prints a privately printed book, I will check the typos. The paper is better than the original.

"What does all this prove?" Mr. He had such a good impression of Wen Qin that he couldn't bear to doubt anything.

The professor was silent for a while: "I don't know either."
