Then he pointed to the ruler and said...

"Now, I'll ask you, if the hook is three times long and the strand is four times long, how long should the string be?"

Upon hearing this, the disciples present were completely at a loss. They exchanged glances and shook their heads repeatedly.

"have no idea."

Upon hearing this, the scholar snorted coldly.

"I just taught you this a few days ago, and you've already forgotten it."

"Alright, I'll say it to you again today. If you can't answer clearly when I ask you later, then I'll hold you accountable."

After he finished speaking, he pointed directly ahead.

"If the hook is three and the leg is four, then the hypotenuse should be five."

"Because that's how the Pythagorean theorem and the chord are calculated."

"If the hook is three, then three times three is nine."

"The number of shares is four, four times four is sixteen, and adding nine and sixteen together gives twenty-five."

"This twenty-five is five multiplied by five, so the chord is five."

"Therefore, the right triangle is 3-4-5, do you understand?"

The disciples below shook their heads repeatedly, as if listening to something completely foreign to them.

"What an idiot! It's just that the length of the leg is multiplied by itself, and the length of the spur is multiplied by itself. Adding the two together gives you the length of the hypotenuse multiplied by itself. Don't you even understand something as simple as this?"

"Didn't I tell you before that I was going to prescribe a medicine?"

"Don't you understand this?"

"You don't even know how to extract a root?"

After saying that, the old man swung the ruler down hard again, hitting the people so hard that they grimaced and cried out for a long time.

After that, the scholar lost interest. He waved his hand and then gestured for his disciples to leave.

"Alright, you can go and study on your own now."

"You can go down and think about it yourselves."

"I won't keep you company any longer."

After he finished speaking, the disciples immediately bowed and paid their respects, and then they vanished into thin air.

Immediately, the two great scholars walked to the front of the barrier and calmly looked outside.

"Now you should understand what a Pythagorean theorem is, right?"

"Tell me, did you understand?"

Yang Fan was taken aback upon hearing this.

To be honest, he didn't understand the Pythagorean theorem very well. Although he had a general idea, he was afraid it would still be difficult for him to calculate it.

Unexpectedly, at that moment, Xiao Ling stepped forward and lowered her voice.

"Kid, hurry up and say you've learned it, then answer."

"If you delay any longer, you might be held accountable."

Hearing this, Yang Fan gave a wry smile. He looked at the others and saw Xiao Baihua and Gan Lu staring at each other, while Luo Changhe looked up at the sky.

He understood that these people were obviously unreliable.

He had no choice but to nod, even though he was reluctant.

"Yes, kid, you know what to do."

"Alright, I'll give you a problem now, and you can solve it."

Now, the length of the hook is eight, the length of the leg is fifteen, what is the length of the chord? Can you calculate it?

The two Confucian scholars looked at Yang Fan with great hope.

The length of the hook is eight.

Yang Fan grinned; it was indeed quite difficult for him to calculate.

Thinking of this, Yang Fan could only lower his head and silently calculate in his mind.

Xiao Ling reached out and grabbed Yang Fan's shoulder.

"Kid, don't try any tricks, you have to figure it out."

"If you can't figure it out, I have plenty of ways to make you feel better."

Then he clenched his fists, looking like he was about to torture Yang Fan.

Yang Fan could only nod helplessly and hurriedly began to calculate.

After a while, Yang Fan tentatively looked at the Confucian scholar.

"The string length should be seventeen, right?"

Yang Fan had just done a quick mental calculation, and he wasn't entirely confident.

Upon hearing this, both scholars beamed with joy.

"That's right, that's right, it really is seventeen."

"You're definitely a promising young man."

The two men then waved their hands, and a passage immediately appeared on the other side of the barrier. They then beckoned to Yang Fan and gestured for him to enter.

Seeing this, Xiao Ling wanted to jump in.

Unexpectedly, at that moment, one of the scholars pointed forward, and a beam of light shot out from the ruler, which actually blocked Xiao Ling.

Then another person reached out and grabbed Yang Fan, forcibly pulling him inside.

"Damn it, we came here together, we should have gone in together."

Upon hearing this, the two glanced at Xiao Ling and then smiled slightly.

"If you can also answer the Pythagorean theorem, then we can naturally..."

He was about to pose a question.

Seeing this, Xiao Ling immediately covered her ears and even stepped aside to sulk.

Clearly, given her mathematical abilities, it was impossible for her to understand these things.

After entering, one of the Confucian scholars bowed to Yang Fan and then handed him the ruler he was holding.

"This item has been with me for many years and has served some purpose. You might as well accept it."

Upon receiving the ruler, Yang Fan merely touched it lightly, and his eyes lit up immediately. The ruler was clearly a top-grade magic weapon.

Just as Yang Fan was overjoyed, he glanced at Xiao Baihua and the others behind him who were full of hope.

Yang Fan knew that even if he accepted this item, it probably wouldn't end up in his hands.

Yang Fan wanted to refuse.

But the two of them waved their hands repeatedly.

"Take it; consider it a favor to you."

Then one of them waved his hand, and another jade slip flew over.

"Here are some things about the Pythagorean theorem; you might want to take a look."

Upon hearing this, Yang Fan nodded repeatedly.

He then followed suit, carefully searching through the jade slip until he found the jade pendant fragment. He immediately and quietly put the fragment away again before pretending to examine the contents of the jade slip.

The contents of this jade slip are all about how to calculate these Pythagorean theorems.

After looking around, Yang Fan became more and more familiar with the Pythagorean theorem.

He then took a deep breath and carefully withdrew with the jade slip in his hand.

After the barrier in front was removed, Yang Fan returned to Xiao Baihua's side.

Xiao Baihua snatched the ruler and jade slip from his hand. He then threw the ruler to Luo Changhe, who was standing to the side, for him to examine, while he himself began to read the contents of the jade slip.

After looking around and confirming that it was just some math stuff, he became increasingly bored.

"What, is this all there is to it?"

Yang Fan nodded.

"That's all there is."

Then, Luo Changhe, who was standing to the side, nodded.

"It's just a top-grade magic weapon, nothing else."

Finally, he handed over the magic weapon.

Then, Xiao Baihua wanted to take the ruler.

Luo Changhe snorted coldly.

"This is something Young Friend Yang obtained; what right do you have to take it?"

"Return it to Young Friend Yang."

"This is what young friend Yang deserves."

Finally, he snatched the ruler back and handed it to Yang Fan.

Xiao Ling, standing to the side, was somewhat dissatisfied, but upon closer reflection, she realized that a small act of impatience could ruin a great plan. In any case, she would have to kill Yang Fan afterward, and the items would eventually belong to Xiao Baihua anyway, so it didn't really matter.

Therefore, she remained silent.

Then, the group left the palace and continued on to the next one.

The Nine Chapters Palace consists of nine palaces, each corresponding to one of the nine mathematical disciplines in the Nine Chapters of the Mathematical Classic, which they naturally value highly.
