He just started to listen a little, and he knew what the teacher was going to say.

"That classmate, are you so sleepy?" The chemistry teacher on the podium looked at Di Li, who was lying on the desk.

"A little bit, it was too late to play games last night." Di Li raised his head and answered the teacher

"Are you so confident?" Of course, the chemistry teacher knew Di Li and knew that he had good grades in high school.

But now it has been three years, he should have almost forgotten about it.

"Not really, the main reason is that I didn't expect that I would be arranged to attend classes with Senior Three."

"Besides, it's okay, sir, to frighten them with this topic. As for me, I really can't frighten me." Di Li's tone was a bit arrogant, but the chemistry teacher asked him: "The large-scale production of magnesium powder in industry is the reason for this." To cool magnesium vapor in a gas, what can be used as a cooling gas?"

Di Li, who was questioned, said: "Carbon dioxide, argon and hydrogen."

Di Li replied without thinking, and the teacher was a little surprised.

"Okay, then let me ask you, why doesn't magnesium react with hydrogen?" The chemistry teacher continued to ask Di Li.

"Because magnesium can only be used as a reducing agent, its lowest price is zero."

"Hydrogen can only be used as an oxidizing agent, and it is reduced by itself. The reducing property of magnesium is not enough to reduce hydrogen to a negative value..."

"And, teacher, this doesn't seem like a high school course, does it? You won't take the college entrance examination."

"Woohoo!!!!"

Di Li's operation made the whole class booed.

A top student is a top student, he just knows the answer and the principle as soon as he hears the question.

I even know that this is not a high school course, and the college entrance examination will not be taken.

"Sure, I didn't expect you to know all these three years after the college entrance examination?" The chemistry teacher was also very surprised. Di Li is really a genius.

"It's okay. Although I basically don't need chemistry in my life, I can understand and remember some of these things from reading books." I was arrogant just now, but now I am humble.

"Okay, don't disturb your deskmate."

After the teacher finished speaking, Di Li also turned to look at Guan Xiaotong beside him.

The latter blushed when he saw her, and knew that he was peeking at her, but she just didn't want to turn her head to look at him.

Because there was a camera behind him, and he was wearing a headset, Di Li didn't dare to say that.

Avoid the embarrassment of being recorded and then broadcast through the program.

"I took the wrong book, chemistry class." Di Li reminded Guan Xiaotong that he took the wrong book.

Di Li is a little strange, is this a science class?Why is there a chemistry class in the third year of high school?

Although strange, but did not ask.

"..." Guan Xiaotong was even more embarrassed now.

Then he closed the book silently, and then took out the chemistry book.

Now she just wants to find a crack in the ground to get in.

"Did you use the lipstick I gave you?" Di Li looked at Guan Xiaotong's lips and asked her. ,

"No, mine." Guan Xiaotong didn't even look at Di Li, and lied and denied it with a blushing face.

"Oh." Not even if he didn't say hello.

Di Li didn't speak, and continued to sleep lying on the desk.

To be honest, it's really boring, if it's not for the exposure, to promote my TV series.

He really didn't want to do such a show before.

The main thing is that he knows and remembers all these knowledge points.

To be honest, it’s not bragging. If you let him take the college entrance examination now, if you take the exam seriously, you will get a perfect score in the college entrance examination.

At the beginning, it was only more than 710 points, and that was because he didn't take the test seriously and just wrote it casually.

When Di Li was sleeping, Guan Xiaotong reached out to his thigh and squeezed it politely.

"Oh!!!" Di Li, who was soundly asleep, felt a pain in his thigh, which made him howl subconsciously.

The sudden wailing made the whole class look at him.

Di Li also realized something at this time, and then looked at the teacher on the podium.

"Student Di Li, no matter how good your grades are, you can't disturb the class like this." The chemistry teacher asked helplessly

"No, teacher, I, I, I..." Di Li, who wanted to explain, glanced at Guan Xiaotong next to him, and then grabbed her hair: "It was Guan Xiaotong's desk and my desk that caught my flesh."

Guan Xiaotong was secretly happy in his heart, but he also knocked off his hand: "You deserve it, letting you sleep interrupts my study."

"No, I don't snore when I sleep, how does it affect your study?"

"Brother, if you sleep, you will make people around you feel sleepy too." Guan Xiaotong's words were correct, but Di Li couldn't find a reason to refute.

Under the teacher's signal, Di Li sat down, and then gave Guan Xiaotong a vicious look.

Although it is said that when the teacher is in class, I have to listen to the lecture. This is the respect for the teacher, which is right.
