Cheng Nuo pointed at himself and said with a dry smile: "Teacher, the person you are talking about can't be me, right?"

"What do you say?" said Old Tang with a smile.

"Teacher...... Can I refuse?" Cheng Nuo said with a wry smile.

"What do you say?" said Don still smiled.

"Uh...... All right. In this regard, Cheng Nuo could only reluctantly accept it.

Since the last time Lao Tang asked Cheng Nuo to come to the stage to give a lecture and messed up, it seems that Lao Tang has not let Cheng Nuo on the podium for a long time.

This time, he actually asked Cheng Nuo to take his own class, I don't know who gave Lao Tang the courage, Liang Jingru?

Either way, the matter is settled.

"You're going to tell me a good story tomorrow, do you know? We must let the students understand these questions!" Old Tang finally instructed.

Cheng Nuo patted his chest and promised, "Teacher, don't worry, with my scholarly strength, it's no problem!"

............

Cheng Nuo and Old Tang returned to the classroom together. The students were still in the classroom and struggling with the test papers.

Cheng Nuo slowly returned to his seat and took out a book from his school bag.

A Study of Newton-Leibniz-Green-Gauss-Ostrogladsky-Stokes-Poincaré Theorem

Then pull out another one.

A Study of the Bogoliubov–Born–Green–Kirkwood–Yvon Levels

Combined, the two books are almost as thick as a dictionary.

Cheng Nuo put the two books on the table, turning the pages with ten lines at a glance.

Hao Shuai, who was next to him, looked dumbfounded.

These two books are very hung just by looking at the name, Cheng Nuo is actually reading this!

No wonder Cheng Nuo was able to become one of the new top students in the second middle school in a short period of time, and he was just hovering on the edge of the scumbag.

I don't know when I will be able to become a top student like Cheng Nuo...... The man!

Hao Shuai was melancholy for a while, lowered his head again, and accepted the fate of being tortured by math problems.

And Cheng Nuo, as if the noise around him did not exist, browsed the data in the book at a glance.

The two of them don't listen to the affairs of the world, and only read the books of sages.

is talking about Cheng Nuo's current state. Uh(⊙o⊙)... , although Cheng Nuo himself doesn't know what the use of these two formulas is after thorough research.

But...... The promise he made, with tears in his eyes, will also read him.

When the flash flood broke out, I said that once I lived, I must use my abilities in high-end atmospheric places!

............

Bell bell bell ——!

The metallic bell rang for the end of class, and Old Tang slowly got up on the podium, said "Wrap up!", and walked out of the classroom slowly with a thermos cup.

The three class representatives also began to collect the test papers for a while.

Cheng Nuo also gathered around a large group of people, most of whom were one of the thirteen people who climbed the mountain with them a week ago.

On the day of the May Day holiday, a total of 13 people from their 18th class participated in the activity of climbing the mountain in Luoshan.

Among them, Li Yang and the three girls went down the mountain early, so they were naturally fine.

And Jiang Qingqing, Su Xiaoxiao and other seven people, hurriedly and slowly took the cable car and caught the last train at six o'clock in the afternoon.

The flash flood outbreak began at half past six in the afternoon, and because of this, Su Xiaoxiao and the other seven people were not affected by the flash flood.

But Cheng Nuo and Mu Leng are different. They are two people who have come out of the torrent by hard life.

The number of victims of the flash flood a week ago has been counted.

Of these, 15 people died, 60 were injured and 10 were missing.

After all, the area of Luoshan is so large, it is not easy to search all of them. To this day, there are still armed police officers and soldiers who have launched a search in Luoshan.

However, a week has passed, and the ten missing people, unless they have the ability of Bei Ye, are more than lucky!

At that time, Jiang Qingqing and others, who had already returned home, were immediately frightened when they saw the news of the flash flood.

They still clearly remember that Cheng Nuo and Mu Leng were still on the mountain.

The first reaction, Jiang Qingqing dialed Mu Leng's phone. Can...... No one answered......

Su Xiaoxiao was also there, and called Mu Leng's phone, but no one answered. When I called Cheng Nuo's phone again, there was still no answer. Su Xiaoxiao was anxious and cried.

"Woo woo, Cheng Nuo, Mu Leng, you must not have anything to do! Woo woo~~"

But they had no other way but to wait and pray.

That night, Su Xiaoxiao stayed awake all night. Have been anxiously waiting for the results.

It wasn't until the next day that Mu Zhengdao sent a message saying that Mu Leng and Cheng Nuo were safe, and a hanging heart was put down.

After all, he had to pull Mu Leng to challenge the gossip array around the mountain. If the two of them were killed in this flash flood, Su Xiaoxiao would feel guilty for the rest of his life.

"Cheng Nuo, you don't know how worried I was about you that day. Su Xiaoxiao pouted and said, "I'm worried that I've eaten a few packs of potato chips." So, how are you going to compensate me?"

Cheng Nuo Great Khan, Waterfall Khan. Xiaoxiao, are you here to care about me? Are you sure it's not for snacks?!

"Then I'll bring you snacks next time. Cheng Nuo completely grasped Su Xiaoxiao's thoughts.

"Okay!" Su Xiaoxiao's excited cheers pushed Mu Leng from the crowd of onlookers to Cheng Nuo.

winked at Cheng Nuo with a little meaning, and then quickly disappeared from the sight of Cheng Nuo and Mu Leng with a Lei Feng mentality of doing good deeds without leaving a name.

Cheng Nuo and Mu Leng, the two of them were watching each other under the watchful eyes of more than a dozen classmates.

The eyes of both of them were full of mixed emotions.

After a few seconds of silence, Cheng Nuo's gaze gradually returned to calm, leaning back in the chair, and said with a smile, "When did you come back?"

"I came to school after a day in the hospital. It's just a fever and dehydration, it's not very serious. After a day in the hospital, I was almost recovered. My parents said that learning is the most important thing. So I came to school the next day. With Mu Leng's cold character, this is probably the longest sentence Mu Leng has said so far. And also to a boy.

But...... Cheng Nuo's focus does not seem to be here......

Why can Mu Leng enjoy a comfortable campus life the next day, but he can only stay in the hospital where there is no mobile phone, no computer, and only one TV can be received for seven days. Tragic!

"Cheng Nuo, that day...... Thank you so much. Mu Leng whispered to Cheng Nuo with gratitude in his tone.

The more I experienced it, the more I realized how dangerous flash floods can be.

In the face of such natural disasters, a person's strength is too weak and too small.

Mu Leng knew that if it weren't for Cheng Nuo, he would probably have died in the torrent three times!

Mu Leng's cold personality does not mean that she will not be grateful.

Cheng Nuo's care for her along the way, she saw it in her heart and remembered it in her heart.

In Mu Leng's heart, Cheng Nuo has changed from the image of a junior good person, huh...... Upgraded to Intermediate Good Guy!
