"Master, please tell me the correct answer..."

Wang Dingjue knelt in front of Zhao Hao, looking at his disheveled hair and bloodshot eyes, no wonder his brother thought he was crazy.

Wang Xijue hurriedly reminded in a low voice: "Brother, you are the same generation..."

"Go away, I don't have a brother like you." Wang Dingjue suffered inhuman torture in the past two days. He was stabbed by a witch, poured incense and ash water into his mouth by the old Taoist, and was whipped by a sage by a sage. He was so humiliated that he was dying.

Moreover, this humiliation actually came from his dearest brother, which made Wang Dingjue even more unacceptable. He glared at Wang Xijue with his eyes blazing fire and said:

"Wang Xijue, I will never forgive you in my life!"

"This, this..." Wang Xijue made his younger brother blush and rubbed his hands awkwardly: "If you do this, anyone would think you were crazy."

"Where am I crazy? Didn't I tell you that I'm fine, I'm very sober, have I never understood that way?" Wang Dingjue asked angrily.

"No madman admits that he is crazy..." Wang Xijue muttered in a low voice. He was a little silly and didn't know how to coax his younger brother to speak.

Naturally, Wang Dingjue became more and more popular. His eyes were red like bullfighting, and he was about to jump up and fight against him.

Zhao Hao was originally thinking about watching the show. After all, Wang Xijue's funny drama was an important pastime for the people during the Longwan period.

Now the protagonist is giving a wonderful performance on the spot, so you can't miss this opportunity.

However, seeing that the funny drama showed signs of ethical tragedy, he had to speak to Wang Xijue: "Get the book."

This sentence is better than the red cloth, and Wang Dingjue's attention was distracted and he looked at Zhao Hao with excitement on his face.

"What book?" Wang Xijue was stunned, then slapped his head and said, "Oh, you said that monster..."

Before he finished speaking, he saw Wang Dingjue and Eryang showing murderous gazes. He had to change his words quickly and said, "Geometry is the first to see, geometry is the first to see."

"You won't ruin it, right?" Zhao Hao asked. Usually, there are steps to burn unclean things in such large rituals.

"No, I just burned the ghost painting talisman he wrote. The book is still preserved." Wang Dingjue greeted the housekeeper and brought a wooden box covered with talismans.

"Uncle Shi is really willing to pay for his capital." Hua Shuyang couldn't help laughing at this. He knew that those talismans all claimed to contain magic power and were calculated based on the money.

"Oh, what money is not worth? It's all for him to recover as soon as possible. Don't delay the test?" Wang Xijue looked at his younger brother helplessly, looking like a parent who was not understood. In fact, if the spring exam was not imminent, he wouldn't be so nervous.

Wang Dingjue just tilted his head and snorted.

~~

Wang Xijue tore open the talisman, took out the key, and took out a wooden box with seals from it.

Zhao Hao and others could see clearly that the seal read "It's Om, well, Ni, Ba, Mi, Hum". The corners of their mouths twitched. This old king also practiced the three practices of Confucianism, Taoism and Buddhism.

"Isn't this a rush to seek medical treatment? I'm thinking about asking for more companies, and there will always be a useful thing."

Wang Xijue embarrassedly uncovered the seal and took out the sealed "A First Look at Geometry".

As soon as he saw the book "The First Peeping of Geometry", Wang Dingjue immediately became energetic. He jumped up from the ground like a cat, held the book in his hand, then jumped back to Zhao Hao and knelt down. He turned to one of the pages, raised it high above his head and said:

"Teacher, this question is too difficult, I don't know how to do it!"

Zhao Hao took the book and saw that it was the Proposition 11 of the second volume. The original title is 'You can divide a known line segment so that the area of ​​the rectangle formed with a small line segment is equal to the area of ​​the square where the remaining line segment is the edge'.

Of course, in order to meet the habits of scholars and officials, Zhao Hao specially gave classical Chinese and replaced the letters with twelve heavenly stems such as ‘A, B, C, D’.

Zhao Hao smiled slightly and couldn't help but praise: "It's hard to see this, it can be said that it's rare."

These words are sincere.

"Student is foolish, and there are many propositions in front of me that I can't figure it out. It's just that this question makes me most obsessed." Then Wang Dingjue said with a confused look on his face:

"I always feel that this division is so mysterious, and I'll fall into it without knowing it."

"Yes, this point is the so-called golden division point." Zhao Hao laughed and said to his apprentice: "Who will deduce it for him?"

Wang Wuyang immediately raised his hand.

Hua Shuyang was slowing down and had to withdraw his hand, lay the paper for his senior brother, and then took out a ruler and pencil from his treasure bag...

Because the brush cannot be used to make drawings with ruler, Zhao Hao wanted to invent the pencils earlier. But the students understood what he meant and did not dare to remind the teacher directly. Instead, they bought a box and placed it on his desk. Only then did Zhao Hao realize that pencils had already existed in the Ming Dynasty.

Wang Wuyang told him that this thing is called "lead" and is made of graphite as powder and rubbed with glue, and can be used directly for writing. In the scriptures passed down from the Tang and Song dynasties, a common boundary called "black silk railing" is drawn with pencils.

It was just because Zhao Hao didn't pay attention to it because he was not very commonly used, so he made a mistake.

Seeing that the master also didn't understand something, Eryang not only did not feel it was shattered, but instead felt closer to the master.

After all, omniscient saints can only worship them. Only those who are confused by flesh and blood will make people feel intimate.

~~

"This question is actually not difficult, but it needs to be proved based on the sixth proposition in this chapter..."

Wang Wuyang explained while making pictures, and made it clear for Wang Dingjue.

Even Wang Xijue, who was on the side, was alert to observation, showed a look of surprise.

After all, the beauty and pleasure contained in that clever and rigorous derivation process is, to some extent, no less than reciting a majestic article or reciting a famous poem.

When Wang Wuyang finished his explanation, Hua Shuyang, who couldn't help but snatched the pen and ruler, then showed off:

"In fact, this point can also be found using the Pythagorean technique of our ancestors. If you don't believe it, let's assume that the length of the slit of a triangle is twice the length of its hook, then the sum of the slits of this triangle is equal to the difference between the slits and the sum of the slits and the golden division of the slits. The problem is solved. Master, am I doing this right?"

"Oh..." Wang Dingjue suddenly realized and said excitedly: "I'll just talk about this mystery? It seems to be a different source of Pythagoreans, but it's still in Pythagoreans!"

In fact, Zhao Hao also wanted to say "Oh" because it was the first time he heard about the solution outside of this textbook.

But considering the decentness of his teacher, he could only pretend to be profound and nod slightly, indicating that Hua Shuyang did a good job and was right.

Alas, there is no way to be a teacher for a genius disciple. It is just that boring, guilty, and easy to hurt self-esteem...

"Now you understand? Why does the family teacher only give the proposition but not the deduction process? He is afraid of limiting our thinking." Seeing Zhao Hao nodding, Hua Shuyang's excited face turned red, and he shouted excitedly: "The family teacher is asking us to break the rules and learn to think independently!"

Zhao Hao had no choice but to nod, in fact, he was just deliberately digging a hole and waiting for someone to jump in...

"Yes, this is all the hard work of the master!" Wang Wuyang also emphasized the key point: "This is the spirit of science, the qualities that a master must possess!"
