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

Wen Qin tore open the envelope directly, only to find out that Qi Hong and Yan Mengjuan found out after returning home that their teacher had returned to the capital.

They were both a little anxious because, according to their understanding, the teacher's husband had passed away due to illness a few years ago and his children had long lost contact with him.

He was in poor health and returned to the imperial capital alone. Qi Hong and Yan Mengjuan were very worried.

So they wrote to Wenqin and asked her to see if she could find their teacher, see how she was doing, and then write a letter to them.

Their teacher left them his address before leaving.

Wen Qin took a look at the address left, which was not far from the courtyard she rented, so she decided to go there today.

First, I bought a box of local snacks, wrapped them in oil paper, and hung them on the handlebars of my bicycle. Then I started asking around in the alleys. When I found the place, Wenqin was a little surprised.

This is a relatively well-preserved courtyard, but the yard is a bit messy and is divided into several parts, some of which are used as kitchens, some face the coal pile, and some are used to dry clothes.

A middle-aged woman squatting over there burning the stove was surprised to see Wen Qin: "Girl, who are you looking for?"

Wen Qin smiled and said, "Aunt, I'm looking for an old man named He Zhengliang. Does he live here?"

The middle-aged woman showed a trace of surprise on her face, and looked Wen Qin up and down: "Who are you to him? What do you want to see him for?"

Wen Qin thought that he had found the right place, so he said, "I am a friend of his student. His student heard that he had returned home and could not come to the capital for the time being, so he asked me to come and see him."

The middle-aged woman nodded and muttered something. Wen Qin didn't hear it clearly. Then she looked up and shouted, "Lao He, I'm looking for you."

There were noises in the only room in the middle that was not cluttered with things. Then the door opened and a man wearing blue work clothes, a hat and black-framed glasses, with an almost invisible face, staggered out of the room on crutches.

He reached out and lifted his glasses, obviously wanting to confirm Wen Qin's identity, but in the end he found that Wen Qin was a stranger, so he asked in confusion: "Looking for me?"

Wen Qin parked her bicycle and smiled at the old man, "Hello, Mr. He. I am a student in the Computer Science Department of Shuimu. I live in the same dormitory with Qi Hong and Yan Mengjuan."

"Hey, Mizuki's college student!"

Before He Zhengliang could say anything, the woman who had been squatting over there tending the stove immediately called out, looking as if she was watching a foreign spectacle, which scared Wen Qin.

Wen Qin could only smile at her shyly.

He Zhengliang relaxed when he heard the names of Qi Hong and Yan Mengjuan: "Xiao Hong and Juan Juan's classmates, then come in, it's cold outside."

Wen Qin hurriedly followed Mr. He into the house. The aunt outside who was watching the fun looked like she was about to pounce on her.

After entering the house, Wenqin found that the dirtiness and mess inside and outside were completely two different worlds.

Perhaps because there were thick curtains covering the room, a stove burning charcoal and a pipe connected to the outside, the room was very warm.

The tables, chairs, windows and cabinets inside are all antique, but the colors and styles don't seem to match.

There was a rattan chair with a thick cushion. Mr. He put his crutches on the side and reached for the blue and white porcelain teapot with trembling hands.

Wen Qin hurriedly went up to help: "Teacher, please sit down, no need to entertain me, I can do it myself."

Mr. He let go of the teapot, sat down on the rattan chair with a smile, and pointed to the chair next to him: "Little girl, sit down."

Wen Qin held the teacup with water in her hand and sat down respectfully.

Mr. He smiled and said, "Judging from the girl's accent, she is not from the imperial capital."

Wen Qin nodded: "Yes, I'm from Jiang Province."

The old man seemed very happy: "I also lived in Jiang Province when I was a child. My grandfather worked as the governor of Jiangnan, but we returned to the imperial capital after a few years."

Wen Qin smiled: "That's far away, my hometown is in Jiangbei."

The old man waved his hand and said, "It was far before, but now there is a bridge across the river, so it is not far anymore."

Wen Qin nodded: "Yes, when we get a train and build an airport, it will be even closer."

The old man was stunned for a moment, then he laughed: "It is indeed classmate Wenqin."

Wen Qin was not surprised. She guessed that her two classmates would also mention her when they wrote to the teacher.

"Xiaohong said that you are optimistic and positive, have wild ideas, and are full of hope for the future. She also told me about your future life. Today, I see that it is indeed true."

Wen Qin was a little embarrassed: "I was reckless and thought too much."

Mr. He waved his hand and said, "You are studying computer science, which is the most advanced, cutting-edge and futuristic subject in the world. It would be ok if you were to be dull and gloomy. You are the one who dares to think."

Wen Qin was a little curious: "Did the old man also learn this?"

Mr. He smiled and said, "If I had studied this back then, I would probably not have been able to come back. I later learned computer science little by little by myself, but there was too little information to count for much."

Wen Qin thought, he is indeed a returnee.

As the son of an official of the previous dynasty and a student studying abroad, Mr. He’s previous identity must have been something extraordinary.

Just a quick glance and it seemed full, but in fact, it was not a house very convenient for the elderly person living alone, so Wen Qin felt a little concerned.

"Teacher He, Qi Hong and the others are very worried about your life in the imperial capital, so if you have any inconvenience, just tell me. Qi Hong's teacher is my teacher, so don't be polite to me."

He Zhengliang seemed very satisfied with the word "teacher": "Don't be polite, it's not inconvenient for me. Tell Xiaohong and Juanjuan not to worry about me. I will go back to my own home to live my life. There is nothing to worry about."

Wen Qin looked around and looked at the sun: "Teacher He, how about I make you dinner? I'm a good cook."

Mr. He thought about it and finally nodded.

When Wenqin went out, she saw several children in the yard. When the aunt who was lighting the stove saw Wenqin coming out, her eyes lit up and she quickly reached out and pushed the little girl who was hugging her thigh: "Go and call your sister. This sister is a college student. Touch her to learn some knowledge."

Wen Qin was a little amused and confused by the fact that he was trying to gain academic recognition in such a blatant way.

The little girl was obviously very shy and hid behind her aunt. As a result, the older children around her all surrounded her and asked, "Sister, are you really a college student?"

Wen Qin was suddenly hugged by someone, she didn't know whether to laugh or cry, so she had to squat down and push the group of kids away: "Yes, I'm in college, but now I have to go to make dinner for Teacher He inside, can you guys give way?"
