Learning Demon Cultivation System

He secretly opened a crack in the door and peeped in.

This peek is just a stare.

Outrageous!

The two were not overwhelmed at all.

Instead, they are whispering!

In fact, as soon as Zhu Hongbo left, the conversation had already begun.

First of all, Li Zheng pretended to be talking to himself.

"Old Zhu came up with this question... on purpose..."

"Hmm..." Lin Yujing sent a response that wasn't really a response.

After struggling for a while, Li Zheng struggled to pull up the chair: "Do you want to unite?"

"..." Lin Yujing also struggled for a moment, then nodded "Hmm".

After that, the two got closer and closer until they got together.

Whispering, endless.

"Yes, first prove the lemma, and then prove the more general proposition."

"Well... the big idea, the disproof and contradiction in the middle, I thought about it as soon as I came up, but I couldn't find a suitable algebraic variant."

"I have this, look at this identity..."

"!!! It really is a scum suitable for foolish mechanical calculations!!!"

"Mao, I thought of this as soon as I came up. It's the intuition of the mathematical brain."

"Scrap! This is all out, and it will be super simple to prove later."

"Is that... oh? That's it! She is indeed a lazy woman who is opportunistic."

"Slag! Pinch you!"

"Am I wrong? Aren't you opportunistic?"

"..."

"Aren't you lazy?"

"..."

"Aren't you a woman?"

"...Scumbag! I have already proved your ability to tell lies."

"Damn... wait for me... let's hand it in together, let's put aside the ones between us first, and make it public."

"Well, Zhu Zhu was scared to death."

After the two decided on their strategy, they pulled their chairs back to their original positions before Zhu Hongbo came back.

Of course, Zhu Hongbo personally witnessed the second half of the process.

His eyes were bloodshot by now.

Damn, isn't it what you guys want to compete with?

How come they are unanimous?

At this moment, Zhu Hongbo realized.

Little two... two little classmates are fighting, the best way to persuade them to fight.

is to become their common enemy.

Zhu Hongbo originally wanted to push the door open and go in.

But looking at the virtues of the two, he just sighed, and slipped back to the corridor with the thermos cup behind his back, walking all the way to the window.

Able to use mathematics to fight against the enemy and move forward side by side...

Isn't this a great happiness.

While Zhu Hongbo was sentimental, he also felt inexplicably sad.

After all, my wife doesn't want to talk about maths except when she takes away her salary...

It's hard to imagine that a 40-year-old man would be sour.

Zhu Hongbo raised his arm and glanced at his watch, trying to swallow the sour taste.

The beauty of adults is also limited, give them another 5 minutes.

After all, even 50 minutes, 500 minutes, the result is still the same.

Impossible, they can't solve this problem.

Five minutes later, Zhu Hongbo opened the door of the office.

After Li Zheng and Lin Yujing exchanged small glances, they got up at the same time.

"finished."

"Well."

"Hmph." Zhu Hongbo only replied with a sneer, not caring about the pettiness between them.

He took the answers from the two, walked to the table, and laid them side by side.

The left and right sheets of paper were examined line by line simultaneously.

almost the same.

Ok……

Prove a lemma first, this step is correct, but it is estimated that this step is correct.

Then there was the assumption...the assumption was correct.

After that……

and many more……

Can they figure out this identity? ?

After that, there are turning points, variants, contradictory proofs...

Then, generalize the lemma to prove a general proposition with universal applicability.

Finally, the existence of N is proved.

In just 1 minute, Zhu Hongbo completed the marking.

No need to read it a second time, the idea is very clear.

Then, big beads of sweat dripped down.

The skin also trembled.

This fucking...

It doesn't make sense...

Behind Zhu Hongbo's trembling body, Li Zheng and Lin Yujing exchanged small glances at the same time.

comfortable.

Awe does not exist.

After a long period of self-doubt, Zhu Hongbo stared blankly at the two scrolls, and said in a trembling voice, "You... you two... tell me the truth... have you looked for the answer?"

The two were taken aback, facing this, they naturally felt a little guilty.

Li Zheng lowered his head and said, "To be honest, Mr. Zhu... I saw Lin Yujing's thinking."

Lin Yujing also murmured, "I used Li Zheng's identity..."

"Except for this?" Zhu Hongbo stared and asked with tremors, "Did you find this question online? Have you seen it before? Did you get ideas from places other than yours?"

The two shook their heads at the same time.

"Damn it." Zhu Hongbo swears, and sits down on the chair, "You two...too much..."

"It's not too difficult." Li Zheng scratched his head.

"Isn't it just an identity equation?" Lin Yujing also felt that Zhu Hongbo had overreacted.

"Fuck." Zhu Hongbo cursed again, then picked up two answers and yelled angrily, "Do you know what this question is? IMO real question! Only 35% of IMO contestants have solved this question!"

The two opened their mouths at the same time.

IMO, International Mathematical Olympiad.

This is undoubtedly the most grand and top-level mathematics competition.

Hello, Zhu Hongbo!

Use this kind of thing to bully people!

There is no doubt that the number competition is going to be held, but it is still in the very basic preparation stage. Now I will take the IMO real questions, Lao Zhu, you are really ruthless!

However, this hatred is over.

Only then did they understand that Zhu Hongbo's trembling was not from anger, but from excitement.

It's exciting to be able to solve IMO problems with very limited training

But Li Zheng and Lin Yujing were far less excited than Zhu Hongbo.

"There's nothing to be happy about. I'm still far behind..." Li Zheng clenched his fists and said, "I can't do it by myself. After more than an hour, even the big idea is a mess."

Lin Yujing also lowered her head: "I haven't been able to find the identity equation either. I don't have enough time, so I can't solve this problem."

"Where is this?" Zhu Hongbo got up excitedly, grabbed the shoulders of the two of them and said, "I just realized now that the strengths of the two of you are completely complementary, one is a strategist, the other is a practitioner. One One is stronger than unconventional thinking, and the other is stronger than unconventional calculation. If it is possible...it is possible...you two must not be separated in the future! You must cooperate together!"

Zhu Hongbo was too violent, which made both of them flinch.

After Zhu Hongbo got excited, he also knew that he had slipped his words: "I... I said that we are working together in a project, not that kind of being together. Of course, that kind of being together is also possible...hahahahahaha..."

"Dong dong dong".

There was a knock on the door.

Tang Zhifei and Tao Feifei suddenly appeared at the door.

"Mr. Zhu, please come out and talk." Tang Zhifei hooked his hands.

Tao Feifei covered her face and snickered: "Well...it's really stable...mathematics really has a natural depth."

Chapter 247 Condoms Condoms Condoms

Zhu Hongbo blushed when he saw the two teachers at this time, and scratched his head in embarrassment.

"Ah, ah, accidents, all accidents..."

After turning around and giving some instructions, he pushed the two female teachers out of the office.

After closing the door, he lowered his head and told the truth.

"I was wrong, I couldn't hold back..."

"Hehe~~" Tao Feifei raised her hand to cover her mouth, and smiled happily, "Now you know how I feel?"

"Isn't it stable?" Tang Zhifei took Tao Feifei's arm and smiled, "I'm just pointing at you to restrain those two."

"My fault, my fault." Zhu Hongbo waved his hands and smiled wryly, "I judged based on experience, and I have placed them in the position of the most outstanding students I have ever met, but now it seems far from enough, it is myself I have seen too few... But I believe that even if the teacher attached to the Renda University comes, the result will be the same miscalculation."

"What's the matter?" Tao Feifei pouted towards the office.

"Let's just say that." Zhu Hongbo gestured, "My mathematics competition training didn't even finish the basic concepts, and they are already at the level of the national mathematics training team."

"..."

"..."

Now Tang Zhifei and Tao Feifei were also dumbfounded.
