"Ten thousand taels of gold, a hundred hectares of farmland?"

Liu Yizhen was a little funny after hearing the news.

Fan Daoji, who came to report the news to Liu Yizhen, also laughed.

"How can that man have so much wealth? At first glance, he is deceiving the ignorant."

The corners of Liu Yizhen's mouth twitched.

He looked at Fan Daoji angrily: "It's me he wants to deceive."

Fan Daoji: "..."

Fan Daoji asked cautiously: "Does the Duke of Chang'an think he really has ten thousand taels of gold?"

"have!"

The truth about Liu Yi should be determined.

"He is worth more than ten thousand taels of gold."

Fan Daoji was a little dumbfounded. He didn't expect Liu Yizhen to have such a high opinion of Gao Yun.

Liu Yizhen took the question and shook his head after reading it once.

Fan Daoji came up and asked, "Mr. Chang'an, could it be that the question is too difficult and you don't know it?"

Liu Yizhen was helpless: "No, it's just that this question is really easy."

Simple?

Fan Daoji can’t even understand the question, okay?

"Just use the elimination method."

It's just a system of linear equations, which is actually a linear equation of three variables.

In later generations, questions that even junior high school students could solve were too childish for Liu Yizhen.

Liu Yizhen immediately used "A, B, C" instead of "XYZ" to list the equation and solve the answer.

After finishing answering the questions, Liu Yizhen asked another question.

"Go and take it to Gao Yun. I have already written down the solution to the problem on paper. I don't care whether you can understand it or not."

"By the way, let me tell him that it is rude to come back without reciprocating. I also gave him a question and asked him to find the answer and come back to me."

Fan Daoji took a curious look at it after taking the paper.

Um!

I really can’t understand it!

Let’s look at Liu Yizhen’s question again: “Today there are one rooster, worth five; one hen, worth three; and three roosters, worth one. If you buy a hundred chickens for a hundred dollars, ask how many roosters, hens, and roosters are?”

Fan Daoji: "..."

At this moment, Fan Daoji began to doubt his own IQ.

I know all the words, but why can't I understand them?

To be honest, Liu Yizhen's answer to this question is really simple.

It is an integer solution to an indefinite square.

It’s also a junior high school math problem.

If Liu Yizhen asked Gao Yun about the positive and negative prescriptions of Qin Jiushao, Liu Yizhen was afraid that Gao Yun would not be able to think about it.

As for doubling the cube, the square circle, the third angle...

never mind.

Mathematics can really kill people.

Don't kill Gao Yun or make him stupid, then Liu Yizhen will have nowhere to cry.

When Fan Daoji gave the answer to Gao Yun, Gao Yun was dumbfounded.

Before his brain could react, Gao Yun's eyes saw the question Liu Yizhen asked him.

boom!

Messy.

Gao Yun's mathematical system... collapsed.

Fan Daoji suddenly felt a little better when he saw that even Gao Yun looked like this.

It's not that I'm stupid, it's that Liu Yizhen is too evil.

He patted Gao Yun's shoulder sympathetically: "Go and untie it properly. Duke Chang'an said that you can only go to see him after you untie it."

Unfortunately, Gao Yun could no longer hear Fan Daoji's words at this time.

Now his mind is full of "A, B, C" and "chicken".

Returning to his residence in despair, Gao Yun huddled himself in the room and looked at the answers given by Liu Yizhen over and over again.

"I can definitely make it!"

"Three days at most!"

"must!"

Gao Yun's eyes were bloodshot, and he picked up the brush and started sketching on the paper.

A week later…

"I made it!"

"I made it!"

Somewhere in an unknown corner of Chang'an, there was a sound of howling ghosts and howling wolves.

Gao Yun's face looked like a ghost at this time, his long hair was scattered and was so greasy that it could stick up.

But he is full of energy, or can this be said to be... a comeback?

"Mr. Chang'an! I've made it!"

Gao Yun seemed to be crying and laughing, looking up to the sky and roaring.

Gao Yun felt that this week was longer than centuries.

He ran like crazy on the street with his shirt naked, all the way to the gate of Liu Yizhen's mansion, shouting inside: "Mr. Chang'an! You can't beat me! Hahahaha! I can do it! I win.

Alright! Hahahahahahahahahaha!”

The wise man Gao Yun looked like before was completely gone, instead he looked like a madman.

"Mr. Chang'an! I don't believe you can still stump me with any questions! I have now developed a new method! I am now the best arithmetic person in the world!"

Just when Gao Yun was talking nonsense, a waiter walked out of Liu Yizhen's mansion holding a piece of paper in his hand.

"Gao Yun, this is the second question given to you by Duke Chang'an. The Lord said that if you are willing to solve it, you can solve it and come back. If you are not willing, you can go in and see him now."

"hehe!"

Gao Yun took the paper with disdain and saw that it was divided into nearly two hundred squares, large and small.

"Q: Two adjacent squares are colored in different colors. How many colors can be used to color the squares in the picture?"

Gao Yun... died.
