Su Yun had actually found out that the principal was coming, but the principal didn't want to come forward to interrupt them, so he continued to 'guide' Meng Meng.

To be honest, in the past few days, Su Yun really likes to talk to Meng Meng.

Because he found that no matter what he said or how complicated it was, Meng Meng seemed to be able to understand what he meant very quickly.

Sometimes, he feels terrible about his ability to understand, no matter what he sees, he can understand it naturally, as if he can do anything.

But when discussing problems with Mengmeng, he will feel that he and she are the same kind.

The two of them are the same kind of people, so the more they communicate, the more relieved Su Yun will feel in his heart.

Finally, he and Mengmeng said about the same, and suddenly stood up and turned to the principal who had been standing aside for a long time:

"Yo~ Principal, why are you here?"

Zhang Jianguo rolled his eyes:

"If I don't come, you still have to tear down my library?"

"Hehe, principal, you're laughing, why am I demolishing this library? I just think that this library should be like this! Quietly, panicked!"

Cai Zhou nodded in the back, indicating that he agreed.

Zhang Jianguo didn't say anything, and hummed:

"Let me introduce to you, this is my old friend, Cai Zhou, academician of the Yangshen Branch of the Chinese Academy of Sciences, academician of the Department of Mathematics, Academician Cai. ”

"Vegetable porridge?" Su Yun looked at the sloppy old man behind Zhang Jianguo, and said respectfully:

"Hello Academician Cai. ”

Cai Zhou nodded:

"Su Yun, right? Then I'll sell you an old man and call you Xiao Su. ”

Su Yun nodded and asked:

"Well, I don't know ..... principal, you're looking for me?"

Cai Zhou rushed in front of Zhang Jianguo and asked:

"I heard that you finished the quick math problem given to you by the principal in less than three minutes, I don't know if this is true?"

Su Yun thought for a moment, and then said:

"2 minutes and 41 seconds to be exact. ”

Zhang Jianguo:

“。。。。。。。 ”

"Impossible!" Cai Zhou suddenly rushed in front of Su Yun and roared angrily:

"Do you know what 2 minutes and 41 seconds mean? It means that you are 7 minutes and 27 seconds faster than the world's No. 1 speed calculation champion! Nearly 3~4 times faster than him! Do you know what this concept is?!!?

Su Yun looked at Cai Zhou, whose face was flushed and emotional, and asked with a puzzled expression:

"Am I 7 minutes and 27 seconds faster than the world No. 1 champion?"

Cai Zhou looked at Su Yun viciously:

"Yes, the French world speed arithmetic champion took 10 minutes and 8 seconds, now I know that you are a, blow it up!"

Su Yun sneered:

"If he is really 7 minutes and 27 seconds slower than me, what kind of world champion is he? ”

Cai Zhou:

“。。。。。。 ”

Zhang Jianguo:

“。。。。。 ”

Meng Meng looked east and west with a cute face, and seemed to think that this old man was very interesting.

Cai Zhou's face flushed angrily, and he shouted:

"I don't believe it! You can do it for me on the spot! If you finish it in 3 minutes, I will give you the position of academician of the Chinese Academy of Sciences!"

As he spoke, Cai Zhou took out a thick stack of A4 paper from his arms and threw it on the table.

Zhang Jianguo's face was rubbed and twitched, you are this broken thing, have you been hiding in your arms for a day? Also, this academician of the Chinese Academy of Sciences, you said let, then let it?

After all, he didn't stop Cai Zhou, because he knew that once something was related to mathematics, this old thing would not give up.

Otherwise, the whole class wouldn't have called him Cai stubborn.

Su Yun spread his hands and said indifferently:

"Okay, I'll do it, but your academician of the Chinese Academy of Sciences, I don't dare to ask for it. ”

As he spoke, Su Yun sat down, sat beside Meng Meng obediently, and handed Su Yun a pen.

Su Yun touched her head, picked up the pen, and prepared to start writing.

"Wait! I'll count first!"

Cai Zhou took out an ancient watch from his arms, stared at the second hand on the watch, and finally walked to the 12 position, he shouted:

"Let's go!"

Su Yun unhurriedly turned the first page, and after reading the question, he wrote without thinking:

“743182*36474=27106820268”

“896402033033÷68954002541=13”

“2496552453-98254446=2398298007”

“5895558761+911214983+6806773744”

“665703843714÷7315426854=91”

“5959565956*173=1031004910388”

“........”

“........”

“........”

Su Yun picked up the pen and began to write the answer, during which it seemed that there was no time to think at all.

When Su Yun wrote the tenth way, Cai Zhou was already standing in place, his eyes were distracted.

When Su Yun wrote the twentieth way, Cai Zhou's mouth opened slightly, and his eyes bulged out, as if he had seen something unbelievable.

When Su Yun wrote the thirtieth word, Cai Zhou's face was flushed, and his whole body trembled as if his hair had exploded.

When Su Yun wrote the fortieth way, Cai Zhou suddenly laughed wildly.

"Hahahahaha

Interrupted by Cai Zhou, Su Yun didn't write, stopped writing, looked at Meng Meng next to him, and asked:

"How's that? Can you keep up with me?"

Meng Meng was on the side, her small eyebrows furrowed, and her mouth was biting the nail of her thumb.

"No, people are slower than Brother Su Yun. ”

Su Yun touched her head:

"It's okay, you're still young. ”

At this time, Cai Zhou on the side couldn't calm down, three steps and two steps, rushed to Mengmeng, and asked excitedly:

"How much slower, how much slower?"

Meng Meng thought about it and said uncertainly:

"Maybe 20 seconds. ”

"Hahahahaha!"

Cai Zhou laughed out loud again, not at all like an old man.

"You two, come with me! Old man, I will personally lead you into the Chinese Academy of Sciences and personally canvass for you! I promise that this year, I will let you become academicians of the Chinese Academy of Sciences! From now on, you two will be the two youngest academicians of the Chinese Academy of Sciences!"

Zhang Jianguo gave Cai Zhou a thumbs up on the side, and thought to himself: Cai stubborn, if you pull this plague god away for me today, you will be my own brother!

Cai Zhou looked like he was going to pull them away directly, and he didn't mean to invite them at all.

Think about it, Chinese Academy of Sciences, what kind of place is that? That's the highest academic institution in the country!

What is his authority? That's the State Council!

Directly under the highest organ of state power, that is, his position is only below it!

As long as you become an academician of the Chinese Academy of Sciences, a high-ranking official of a province sees you, then he has to be respectful.

Hehe, only a person with a good brain would refuse this kind of invitation.

However......

"Well, that, I'm not interested in entering the Chinese Academy of Sciences. ”

"Hmm.... People don't want to go. ”

Cai Zhou:

“。。。。。。。 ”

As soon as Zhang Jianguo patted his head, he knew that it would be like this!

It seems that the plague god is not so easy to send away!

Cai Zhou looked at Su Yun and Mengmeng in disbelief:

"Are you sure? You don't know what the Chinese Academy of Sciences is?"

Meng Meng was the first to say:

"People know! It's all old grandfathers like you there, Meng Meng doesn't like it there!"

Su Yun spread his hands out, indicating that he was the same.

Cai Zhou looked back at Zhang Jianguo, and Zhang Jianguo nodded with a wry smile.

"Hey, if you don't come to the Chinese Academy of Sciences, it's a waste of talent!"

He looked at Meng Meng, then at Su Yun, and asked without giving up:

"Mengmeng is still young, let's not talk about it, Su Yun, you have such a high talent, are you sure you won't come to the Chinese Academy of Sciences?

Su Yun glanced at this old man a lot, and felt that this 'vegetable porridge' was quite suitable for his appetite.

"No need, Mr. Cai, if you are busy, you can find me at any time, but I really can't enter the Chinese Academy of Sciences. ”

Cai Zhou sighed again and asked:

"If you don't come to the Chinese Academy of Sciences with such talent, what do you want to do in the future?"

Su Yun smiled, glanced at Zhang Jianguo, and said lightly:

"I... I want to be a big star. ”
