Compared with mathematics, it was just a very difficult thing for Lu Jiayi. Physics and chemical biology were simply eye-opening for him.

It turns out that the world has no end. The earth is spherical. There are many planets outside the earth. The sun is not a big fireball, but a star that is many, many times larger than the earth. It turns out that when one substance encounters another substance, it will immediately react chemically, become a new substance, and produce other colors. Human beings were not created by Nuwa, but evolved from a monkey. Giving boys and girls does not look at the belly of a woman, but at the chromosomes.

These things are both incredible and difficult for Lu Jiayi. He is equivalent to reshaping his worldview and living in the fog every day, he simply doubts his life.

He was a little lucky that he had only come into contact with these things after adapting to life in this world. If he learned these things when he first came through, he would definitely collapse.

But overall, these subjects are more interesting than mathematics. He thinks the most boring and boring, and the most difficult one is mathematics. He even wonders, is it really useful to learn these mathematics so profound? Will these things be used in real life after graduation? He doesn't know that these are also very good now.

Fortunately, the mathematics he is studying now is Qi Yang.

Although Qi Yang is a poor student, he is still very good at teaching mathematics in elementary school. Even if he has learned the first year of junior high school, Qi Yang is still more than enough to teach him.

In addition to Qi Yang, Xu Lin would also help him. Seeing that he was still memorizing history and geography while eating, Xu Lin said to him: "Actually, we science students, geography, history, just learn about the same thing. If we don't take the college entrance examination, we will be a little useful when we take the exam. But I heard them say that it's not difficult to get the exam at all, almost everyone can pass it, and the invigilator is also very relaxed. If you don't know how to get it, you can copy it. Zhou Yangliu said that in the last class, the seniors of the seniors in the third year of high school. When they know how to take the exam, some invigilators directly helped the students watch the exam teacher and protected them at the door to ask them to copy it."

"I learned these things either for the exam, or I think you can do them, and I should do them." Lu Jiayi smiled, "By the way, how are you with Zhou Yangliu now?"

After Zhou Yangliu finished the exam last time, she was transferred to the front and became a deskmate with Xu Lin.

"It's still the same. He has that personality and doesn't like me very much, but it's fine. I don't like him much anyway."

"Actually, he is just a stubborn and a little arrogant. If you want to have a good relationship with him, you can take the initiative to talk to him first."

"I know he is like this, but I still can't be friends with him. I think he seems a little unstable. I took the initiative to talk to him some time ago. We had a good relationship, but one day he came late, so I asked him why he came late. As a result, he glared at me and became angry. He said I was too much and he was very careful. Do you think it's annoying?"

Since then, Xu Lin has been too lazy to pay attention to him. The two of them are basically polite now, but they rarely deal with each other.

Lu Jiayi smiled and said, "He is so awkward."

He continued to memorize his history cards. He had memorized them carefully last month, and now he reviewed them from beginning to end, so he would ignore them in the future.

Of course, Lu Jiayi knew that it would be enough to learn these subjects, but the problem was that he didn't understand anything before, and others might have learned enough, so he didn't need to spend any effort on it. But he started from scratch, so he had to learn very well now to be similar to other people's level.

Just like in his era, the most important thing was to get a Jinshi exam, but in addition to the Four Books and Five Classics, ordinary scholars would also learn some piano, chess, calligraphy and painting. This has nothing to do with the exam, but it is related to personal comprehensive quality. A top scholar who is not as good as a piano, chess, calligraphy and painting will be laughed at. High school is actually a stage of laying the foundation. It cannot be said that he graduated as an excellent science student in the future, but he didn't even know some of the history and geography knowledge that high school students knew. This is the reason why he worked hard to study geopolitical history.

Students with outstanding grades like Zhou Yangliu and Xu Lin, even those with science and history and geography are very good, so they stand out because of this. There are few academic top students who are biased towards subjects, and those who are biased towards subjects have geniuses, but certainly there are no academic top students.

Because of his hard study, he learned every day until late at night. The weather was cold, and his hands actually had frostbite and the back of his hands was red and swollen. It was fine, but when he washed his hands with hot water, or when he was lying in the quilt at night, his hands were painful and itchy. He had never suffered such a crime.

Qi Yang bought him two frostbite creams, and he applied them, but it was useless. Instead, he rubbed the quilt so dirty. Lin Xiuying's slap delayed his study and did not let him touch cold water at home. But the frostbite on his hands not only did not decrease at all, but became more and more serious.

Qi Yang bought him the kind of half-gloves exposed on his fingers. They don’t affect writing and can keep warm.

Lu Jiayi thought that gloves were very convenient, so she almost wore them except washing her hands. After wearing them for a few days, Qi Yang couldn't see how frostbite was on her hands.

"Have you applied all the frostbite cream?" Qi Yang asked as he looked at his hands.

"No, I didn't wear gloves. I was afraid that it would get dirty if I got it on the gloves."

"Don't be afraid of being dirty. If it is dirty, I'll give you a new one. I still have to apply frostbite cream. How about frostbite now?"

Lu Jiayi took off her gloves and showed them to him, saying, "I will wipe it all at night."

Qi Yang looked at his hands and felt that it was not healed at all, but instead looked even redder and swollen;

Qi Yang stopped looking at his hands, and felt panicked when he saw them. Lu Jiayi was very white, and her hands were thin and white. Now the back of her hands was swollen like a small steamed bun, and it was as dry as if it was about to crack. He couldn't see this.

"I have to apply it during the day, and if the gloves are dirty, I will give you new ones. There are many at home."

Qi Yang did what he said, and the next day he gave him a stack of gloves, which were more than a dozen pairs. He asked Lu Jiayi to wear one pair a day, and when it was dirty, Lin Xiuying asked him to wash it.

"Don't touch the cold water yourself."

But he himself did not wear gloves. It was cold, especially in the morning and evening. He rode his bicycle with his hands exposed, and his memories were frozen when he looked at it. But Qi Yang said that he was not cold, and his hands were really not frozen at all.

Lu Jiayi looked at Qi Yang's hands and was so envious. She was white and long. She was exposed to playing basketball every day. She didn't have frostbite, but she was so white and beautiful.

New Year's Day is coming, and No. 1 Middle School held a football match. Their school basketball game is actually very common, but the reason why this time caused a big sensation was because a group of foreigners came.

To be more precise, a group of black people came.

Fuchuan County is a small county town in the north, and there are very few opportunities to meet foreigners in daily life. For students of No. 1 Middle School, most of them have seen so-called foreigners for the first time in real life. Everyone’s unification is: “Those people are so dark, much darker than what they see on TV.”

I heard that these black people came from the city and wanted to play a friendly match with their No. 1 Middle School football team.

It is logical that football matches have nothing to do with Qi Yang, but Qi Yang was called to the office by the principal and the others.

The time in high school is precious, and the school did not intend to let ordinary students watch this football friendly match. So they were still in class during the game, and until the afternoon after school, the game was not over, and all the students in the school gathered around to watch it.

Of course, there are also people who haven't gone there, such as Zhou Yangliu. He said disdainfully: "If you have this time to read these things, it's better to do an extra set of test papers."

Most of the students in No. 1 Middle School come from rural areas, few people can play football, and few people can understand football. Everyone is watching the fun. Xu Lin pulled Lu Jiayi over and crowded in the crowd to watch football games.

Among all the students in the school, Lu Jiayi was the most surprised. He didn't know that there were such a dark person in this world. He had never even seen it on TV.

"Which country are they from?" he asked Xu Lin.

"It's from Africa." Xu Lin said.

He actually didn't understand a lot, and probably knew that Africans were black. Just like when talking about white people, the first thing they thought of was Europe and the United States.

These black men were tall and big, and ran very fast, and seemed particularly explosive on the court. Lu Jiayi looked around the crowd and saw Qi Yang sitting next to the principal of the rostrum, talking to him and another black man who was dressed in kind.

"Oh Lu Jiayi, you'll come over to watch the fun too."

Lu Jiayi looked back and saw that it was Jiang Chao.

Jiang Chao probably just finished training and was sweating.

"Do you know why the principal called Qi Yang over?"

"Oh, I'm about to tell you, guess what the principal called him over?"

"Aren't I asking you?"

Jiang Chao smiled and said, "The principal of the high school called him as an interpreter."

Xu Lin asked: "As a translator? What is translating, English?"

"Otherwise, I'll speak African." Jiang Chao teased.

Xu Lin said, "Then he is so powerful and can talk to foreigners."

He had done a good job in English, but he still didn't dare to let him talk to foreigners.

"We only knew that Qi Yang had studied abroad before. He has been in the UK for more than a year. His speaking language is very good."

Lu Jiayi and Xu Lin were both surprised when they heard this.

In fact, Qi Yang's spoken language is very good, and there are already traces to follow. From the beginning, he felt that Qi Yang's English pronunciation was particularly standard, just like in a tape. Even their English teachers couldn't tell the taste.

After hearing this, Lu Jiayi turned her head and looked at Qi Yang. Qi Yang sat generously next to the principal, performing an interpreter expressionlessly.
