Chapter 291 (2/2)

Although he was knocked down by Cheng Nuo today, old Tang is not angry at all.

Cheng Nuo is still a student of his own! From his hands out of such a student, enough for him to boast for a lifetime.

Pa Pa Pa Pa Pa!

Other students in the classroom also applauded. Some of them really admired Cheng Nuo's unique thinking of solving problems, such as Chen Gong. And some of them are pure ignorance.

All of a sudden, the whole classroom Pa Pa Pa sound endless.

…………

In the corridor, Cheng Nuo is reminiscing about the past with Comrade Tang. He saw a little boy, some hesitant toward the direction of Cheng Nuo.

Cheng Nuo knew him. He was Chen Gong who was sitting in the first row of the competition training.

Chen Gong walked to Cheng Nuo hesitantly and raised his head. He was embarrassed and hesitated for a long time before he began to speak shyly, ”schoolmaster, can I add your wechat?”

Cheng Nuo:???

I I wipe it!

For a moment, Cheng Nuo feels a cool air rising from the chrysanthemum to his brain.

A sentence of MMP is enough to express Cheng Nuo's present mood.

Why? Why is it that all the beautiful students who want wechat become shy students?Cheng Nuo subconsciously leans to Lao Tang, ”you What do you want to do? ”

Chen Gong's face rose red, and he summoned up the courage of his whole body and said, ”schoolmaster, I want to be your man!”

”Well, no, no, wrong, wrong, to be someone like you.”

False alarm A false alarm!

Just now, Cheng Nuo almost jumped directly from the fifth floor. It's too exciting.

Chen Gong said the reason why he asked for Cheng Nuo's wechat, ”senior student, I think I can ask you any questions about mathematics.”

”It doesn't matter. Please ask for advice. You are my brother in law, and I will teach you with all my heart. ” It doesn't matter if you ask questions, as long as you are not my person, everything is OK.

After getting Cheng Nuo's micro signal, Chen Gong left happily.

Next, Cheng Nuo and old Tang strolled in the campus for a while. Cheng Nuo originally wanted to invite old Tang to have dinner with him, but he still had a few nights to study, so he could only take another day.

”The day after tomorrow, there will be a lecture for you at school. After you go back, you must prepare well and give a lesson to the group of kids in senior three. Try to let our No.2 Middle School to be the champion in the college entrance examination again. ”

Cheng Nuo smiles bitterly and nods. It seems that no school has ever done it in history.

Farewell to Old Tang, Cheng Nuo found a small restaurant to make do with dinner, and then took a taxi home.

Just returned to the bedroom, Cheng Nuo mobile phone will prompt to receive a new message. I thought it was Mu Leng who sent him the test questions like taking medicine. But I didn't expect to open the wechat and have a look. It was not Mu Leng's beautiful girlfriend who sent the message, but Chen Gong, a shy student who just met today.

Chen Gong: ”whining, is the student there?”

Chen Gong: ”can you help me look at this problem?”

Here's a picture of a picture taken with a mobile phone.
