Han Yuan casually dropped the eraser in his hand on the ground.

He put one hand in his pocket, stood there, looked in Lin Yi's direction, and looked at Lin Yi without giving in.

Originally, he only gave people the impression of being gentle and modest.

But at this moment, Han Won's whole body suddenly gained countless sharp edges.

Everyone around was shocked.

"I left something for you on the blackboard. I hope it can help you solve this problem."

Han Won looked contemptuous.

What he erased from the blackboard were the most important formulas to answer the questions.

What is left behind is nothing more than some trivial and ordinary things.

But when these words came out of his mouth, Han Yuan immediately won the favor of countless people.

At least on the surface, he still gave Lin Yi a hand.

"Why, now it's your turn to solve the problem, why are you still standing there, not moving?"

When Zhao Shengping saw Han Yuan's menacing look, he couldn't help but feel a bit of anticipation in his heart.

Even the way he looked at Lin Yi over there was full of contempt.

Can he compare with South Korean won?

School and momentum are not on the same level!

"Just wipe the blackboard well. You have to write such a simple question and use so many steps. Are you still very proud?"

Lin Yi shook his head slightly and stood in front of the curtain. After briefly looking at the questions, he slowly walked towards the blackboard over there.

"Isn't this a bit too crazy to say? This is still a simple question?"

"I think he doesn't know what the difficulty of mathematical models is at all. Maybe he has never been exposed to mathematical models? After all, he seems to be only a freshman, and it hasn't been long since the freshman year. He probably hasn't taken the first volume of advanced mathematics.

over."

Listening to Lin Yi's words, many people below looked at Lin Yi with a lot of suspicion.

The reason why digital models are called mathematical models.

This is because the concept of the model itself is a three-dimensional image, which is not the same thing at all as ordinary mathematics problems, the kind of mathematics that only stay on paper and answer so-called application problems and proof problems.

It is precisely because of this that the application of various elements and different formulas and theorems involved is particularly important.

Needless to say, the complexity of solving the problem is needless to say.

Han Won only used the entire blackboard to answer this question, and it was considered simple.

"I want to see what this student who is so optimistic about Gu Chujie is capable of."

Director Chen was also very prejudiced against Lin Yigang's words.

In his eyes, Han Won's solution to the problem is not necessarily the optimal solution, but it has reached an extremely high level.

Now that Lin Yi has completely rejected him with just one sentence, isn't it also saying that there are some problems with his strength and vision?

There was a little worry in Zheng Qiuchan's eyes.

She had never seen Lin Yi answer such a thing as a digital model.

The mathematics books she had found for Lin Yi before not only explained formulas, but also had some training questions on numerical models, but those training questions seemed too childish.

Stand in front of the blackboard.

Lin Yi did not pick up the eraser on the ground, but directly stretched out his hand and slapped the blackboard with his palm.

"What is he going to do?"

"Is it possible that you are so angry that you want to smash the blackboard?"

Seeing Lin Yi's actions, many people's expressions changed.

Zhao Shengping subconsciously rushed to stop him.

Director Chen and others' expressions suddenly changed.

Han Won still sneered.

But the next moment, everyone's eyes widened.

"how so?"

"Fuck!"

"How did he do that!"

Waves of exclamations sounded one after another.

In the eyes of everyone, they could only see that Lin Yi slapped the blackboard with his palm, but did not smash it into pieces. The expected loud sound did not appear.

On the contrary, as Lin Yi's palm fell, the various numbers and formulas left by Han Won on the blackboard all turned into chalk dust and fell off the blackboard.

It takes less than a few breaths.

The entire blackboard is as smooth as new.

It's as if no one has ever written or drawn on it.

The degree of cleanliness is much cleaner than that wiped with a board eraser.

Chalk dust flew into the air.

Before everyone had recovered from Lin Yi's palm.

But he could see Lin Yi, standing in the dust, holding one hand behind his back, and then stretched out a finger.

This finger, passing through the layers of chalk dust, looks like a fairy guiding the way out of the dust.

next moment.

Lin Yi's fingertips were stained with dust that had not yet fallen to the ground, and they touched the blackboard.

The students below were all at a loss.

Zheng Qiuchan looked surprised.

Director Chen was completely stunned.

Han Won frowned slightly.

At this moment, the expressions of all the mathematics professors suddenly changed.

The classroom was eerily quiet.

You can hear the needle drop.

Everyone's eyes were focused on Lin Yi's fingertips.

They just saw Lin Yi draw a square on the blackboard with one finger, and then without any hesitation, he pointed out the location of the old well designed in the question one after another.

Next, there is the azimuth axis, plus the coordinates of different points and the location of each optimal solution.

Done in one go.

Lin Yi's face was dull, and the mathematical model illustration that appeared at his fingertips in an instant did not look like he was writing a math problem, but more like he was drawing a picture.

A complete construction design illustration!

Three minutes later.

Lin Yi's fingertips lightly swiped over it, and a line of dust immediately connected the locations of all possible points on the illustrated book.

Lin Yi followed closely, substituting the coordinates in the figure at the end of the mathematical model illustration, and obtained the final complete answer formula.

Lin Yi lightly dusted the dust between his fingers.

When he put his hands away and carried them on his back, all the chalk dust that was flying around him finally settled and fell on the ground.

There was silence.

No one spoke, everyone stared blankly at the blackboard in front of them.

On the blackboard, there are coordinates, illustrations, and formulas.

Everything is available.

And these things combined only occupy a quarter of the blackboard space.

Not only that, the students who watched Han Yuan solve the problem before were somewhat specious and full of puzzlements. Now when they saw the picture behind Lin Yi, all their doubts and confusion were solved.

"The answer... seems to be the same as Han Won's answer just now?"

After a long silence, someone finally spoke with some anxiety.

The voice seemed to be asking, quite uncertain.

"How long did it take him to solve this question?"

Another student asked in a low voice.
Chapter completed!
