A powerful country in scientific research

The next afternoon.

The bell for the last class rang, and people left the classroom one after another, leaving only Su Ran and He Cheng.

Su Ran smiled and said to Xu Kai and Wu Hongying, "Today I will teach you about mathematics. I have sorted out all the knowledge points and formulas. I will talk about each one in a while. After I finish, you can start doing exercises. The most important thing about mathematics is to know how to use it. When doing the exercises, you can always ask me and He Cheng if you encounter any problems."

Xu Kai and Wu Hongying nodded repeatedly.

Seeing that the two of them had no objection, Su Ran took out the knowledge points he had sorted out and gave each of them a copy, and then began to explain.

Su Ran’s talk was lively and interesting, and both Xu Kai and Wu Hongying listened very attentively.

He Cheng was also listening. He looked at the girl talking in front of him, and a smile appeared on his face unconsciously.

This girl seemed to have some magical power. Every time she appeared in front of him, his eyes could no longer accommodate anyone else.

Su Ran, who was speaking very attentively, felt the burning gazes from people other than Xu Kai and Wu Hongying. She tilted her head to look at He Cheng and raised her eyebrows.

Feeling her gaze, He Cheng shifted his eyes elsewhere as if nothing had happened, and he touched the tip of his nose uncomfortably.

When Su Ran saw him look away, she knew he was fine and continued talking.

She talked about mathematics for half an hour, and then He Cheng started talking about physics.

An hour passed quickly. He Cheng had just finished explaining a key point of knowledge. He looked at his watch and it was already seven o'clock.

He said calmly to the three people sitting in front of him, "It's time. Let's stop here for today. Xu Kai and Wu Hongying, you two go back and review what we talked about today, and then finish the few questions Su Ran just left. If you have any questions, come to school tomorrow morning to ask me and Su Ran, how about that?"

Xu Kai and Wu Hongying nodded repeatedly upon hearing this.

Su Ran and He Cheng had invited two people to come home an hour later in order to give them extra lessons, and they were also so careful to help them summarize the key points and difficulties. If they had any objections, they would be ungrateful.

The four of them packed their bags and headed outside.

When they arrived at the school gate, Xu Kai said with a smile, "Wu Hongying and I are going the same way, so I'll take her home. He Cheng, Su Ran is in your hands now, you have to take her home safely."

He Cheng responded with a faint smile.

Then the four of them separated, and Su Ran and He Cheng walked side by side towards the food factory’s staff quarters.

Around seven o'clock, most people in Hai City were eating at home and there were few people on the streets.

It was so quiet all around that the only sound was the sound of two people's footsteps.

Su Ran glanced sideways at the boy next to her.

He was wearing the same white shirt he wore when we first met, and a pair of black trousers. These were very common clothes, but He Cheng relied on his excellent figure and good looks to make the clothes look more noble.

Su Ran glanced at his long legs and asked the question she had always had, "He Cheng, how tall are you?"

He Cheng was a little surprised that she would ask this, but he still smiled and answered: "I measured it once before returning to Hai City, and it was 189, what's wrong?"

Su Ran looked as if he had realized what was going on. "It's okay. I'm just curious. I don't think I'm short, but when I stand next to you, I can only reach your mouth. I'm a little frustrated."

He Cheng laughed and said, "What's so depressing about this? You're not short, I'm too tall. My grandma always said that it takes a lot of fabric to make pants for me, and she looked disgusted when she said that."

When Su Ran heard his words, a picture suddenly appeared in her mind, and then she couldn't stop laughing.

"Grandma is right."

Looking at the girl beside him with a beautiful smile, he also curled up the corners of his mouth.

The awkward atmosphere between the two of them dissipated a lot because of the conversation just now, and they started talking about tutoring.

He Cheng: "Su Ran, your summary of the key and difficult points of mathematics knowledge is really good."

Su Ran waved her hands in embarrassment after being praised. "It's OK, it's OK. You taught physics very well, in a simple and easy-to-understand way. The two of them got a much higher accuracy rate in answering the questions after listening to you."

He Cheng: "I'm still a little worse than you. Besides, I don't have any strong points. I'm just good at studying. I'm very happy to be able to help them." His tone was a little heavy, with a smile.

Su Ran frowned in disapproval.

"He Cheng, don't be too modest. You are full of advantages. You are tall and handsome, and you always rank first in your studies. You are good at math, physics and chemistry, so you can become a teacher. And you speak English so well that you can become a translator in the future. You have to learn to face yourself."

He Cheng's face turned a little red due to the praise, luckily it was dark and the people around him couldn't see it.

He cleared his throat, "Thank you for the compliment, then."

Su Ran didn't feel anything unusual and replied with a smile: "You're welcome."

As the two were talking, they soon arrived at the food factory’s staff quarters.

Su Ran said goodbye to He Cheng and went upstairs.

At this time, Su Jianguo was looking downstairs from his window, and then he saw with his own eyes a boy sending his daughter downstairs. He watched his daughter go upstairs before turning around and walking out of the family compound.

He had seen this boy before. He was the one who helped Wang Zhibin translate documents at the food factory.

When they first met, Su Jianguo felt that the boy's outstanding looks and dignified demeanor made him feel that he definitely did not come from an ordinary family.

Su Jianguo looked at the boy's figure walking away and raised his eyebrows. It seemed that his daughter did not lie to him.

When he has time, he will go and ask Mr. Wang about the boy’s family situation.

Jiang Hongmei was sitting on the sofa watching TV. She saw her husband looking downstairs and asked curiously, "What are you watching? You're watching it so intently."

When Su Jianguo heard what his wife said, he smiled and replied, "Nothing, I just wanted to see if anyone was playing chess downstairs."

Jiang Hongmei thought he was addicted to chess, so she said with a smile, "Uncle Zhang and Uncle Wang are always here, so go ahead and play if you want."

Su Jianguo smiled and shook his head, "Let's do it tomorrow. I'm a little tired today and don't want to go down." After that, he sat next to Jiang Hongmei and watched TV together.

This was the scene Su Ran saw when he came in.

Jiang Hongmei heard the sound at the door and hurriedly looked towards it.

She looked at Su Ran with surprise, "Ran Ran, you're back. You must be hungry. I'll get you some food."

The rice was reserved in advance and kept simmering in the pot.

Su Ran responded with a smile. She put her schoolbag in the bedroom and then sat down at the dining table.

Jiang Hongmei brought the meal to the table and then sat down at the table.

"How was your study today?"

Su Ran nodded, "I feel fine, Mom, are you tired from work today?"

Jiang Hongmei smiled and shook her head. "Why should I be tired? It's like this every day. Ranran, I heard you guys are going to take exams? Don't be too stressed."

"Yeah, don't worry, Mom. When have you ever worried about my grades?" Su Ran curled her lips. Her mother was really worried.

Jiang Hongmei nodded. That was true. Her daughter had never given her any worries since she grew up.

She gave her daughter a few more instructions and then went back to sitting on the sofa to watch TV.

After Su Ran finished her meal, she cleaned up the dishes and went back to her bedroom to continue reading and studying. Studying made her happy.
