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

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

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

"You go away, I don't have a brother like you." Wang Dingjue suffered inhuman torture in the past two days, he was pricked by a witch with needles, poured incense ash water into his mouth by the old Taoist, and was whipped by a god, and the whole person was humiliated to death.

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

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

"This, this ......" Wang Xijue made his younger brother blush, rubbed his hands awkwardly and said: "If you are like this, anyone will think you are crazy." ”

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

"No madman admits that he is crazy...... Wang Xijue muttered quietly, he was a little straightforward, and he didn't know how to coax his brother to speak at this time.

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

Zhao Hao originally had the mentality of watching the play, after all, Wang Xijue's funny drama was an important pastime for the people during the Longwan period.

Now that the protagonist is presenting a wonderful performance on the spot, such an opportunity cannot be missed.

However, seeing that the funny drama showed signs of developing towards an ethical tragedy, he had no choice but to say to Wang Xijue: "Bring the book." ”

These words were better than red cloth, and Wang Dingjue immediately diverted his attention and looked at Zhao Hao with excitement on his face.

"What book?" Wang Xijue was stunned for a moment, then patted his head and said, "Oh, you said that demon ......"

Before he finished speaking, he saw Wang Dingjue and Er Yang showing murderous eyes, so he had to quickly change his words: "Geometry first glimpse, geometric first glimpse." ”

"You're not going to ruin it, are you?" Zhao Hao asked. Usually in such large rituals, there is a step to burn the unclean things.

"No, no, it's just that the ghost drawing talisman he wrote was burned, and the book is still well preserved." Wang Dingjue beckoned to the butler and brought a wooden box full of talismans.

"Uncle Shi is really willing to pay the capital." Hua Shuyang couldn't help but laugh when he saw this, he knew that those talismans were claimed to contain mana, and they were calculated by the sheets.

"Oh, what money is not money, isn't it all about letting him recover as soon as possible, don't delay the try?" Wang Xijue glanced at his younger brother helplessly, looking like a parent who was not understood. In fact, if it weren't for the imminent spring season, he wouldn't be so nervous.

Wang Dingjue only tilted his head and snorted.

~~

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

Zhao Hao and the others could see it clearly, the seal said, 'It's Om, Well, Why, Horn, Mi, Sigh', and the corners of his mouth twitched, this old king is still Confucianism, Taoism, and three cultivations.

"It's not a rush to the doctor, thinking about asking for a few more, it always works."

Wang Xijue embarrassedly unsealed the seal and took out the sealed copy of "A Glimpse of Geometry".

As soon as he saw the book "A Glimpse of Geometry", Wang Dingjue immediately came to his senses. I saw him jump up from the ground like a cat, take the book in his hand, then jump back to Zhao Hao and kneel, turn to one of the pages, hold it high above his head and say:

"Teacher, this question is too difficult, I can't!"

Zhao Hao took the book and looked at it, only to see that it was the proposition eleven of the second volume. The original question was 'You can cut a known line segment so that the area of a rectangle formed by it and a small line segment is equal to the area of the square where the remaining line segments are sides'.

Of course, in order to conform to the habits of scholars, Zhao Hao deliberately gave Wen Yan a little, and replaced the letters with twelve heavenly stems such as 'A, B, C, D'.

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

I mean it from the bottom of my heart.

"The student is stupid, and there are a lot of propositions in front of me that I don't understand, but this question fascinates me the most." Seeing Wang Dingjue's entangled face, he said:

"I always feel that this syncopation point is mysterious and mysterious, and I fall into it unconsciously."

"Yes, this point is the so-called golden section point." Zhao Hao laughed, and said to his apprentice: "Which of you two will deduce it for him?" ”

Wang Wuyang immediately raised his hand first.

Hua Shuyang took a step slower, so he had to withdraw his hand, help his senior brother lay out the paper, and took out a ruler and pencil from the treasure bag he carried......

Because the brush could not be used to draw with rulers, Zhao Hao wanted to invent the pencil earlier. But the students figured out what he meant, and did not dare to remind the teacher directly, but bought a box and quietly placed it on his desk. At that time, Zhao Hao knew that there was already a pencil in the morning.

Wang Wuyang told him that this thing is called 'lead tree', which is made of graphite powder and glue rubbing strips, and can be used directly for writing. In the scriptures handed down from the Tang and Song dynasties, there is a common boundary called 'Wusi Column', which is drawn with a pencil.

It's just that because it's not very common, Zhao Hao didn't pay attention to it, so he made a fuss.

Seeing that the master also had things that he didn't understand, Eryang not only didn't feel disheartened, but felt closer to the master.

After all, the all-knowing saint can only worship, and the flesh and blood who will be confused will make people feel close.

~~

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

Wang Wuyang explained while making pictures, and divided three times by five to give Wang Dingjue a clear and clear explanation.

Even Wang Xijue, who was vigilantly observing on the side, showed a look of surprise.

After all, the beauty and pleasure contained in the ingenious and rigorous deduction process are, to some extent, no less than reciting an eloquent essay or reciting a famous poem.

After Wang Wuyang finished explaining, Hua Shuyang, who couldn't hold back, snatched the pen and ruler again, and then said:

"The Pythagorean technique of its ancestors can also find this point. Believe it or not, if we assume that the length of the strands of a triangle is twice the length of its hook, then the sum of the hooks of this triangle is equal to the difference between the hooks and the strands, and the sum of the hooks is the difference between the hooks and the golden section of the strands, and the problem is solved. Master, I'm doing this, right? ”

"Oh......" Wang Dingjue suddenly realized and said excitedly: "I'll just say this is a little mysterious, right?" It turns out that it seems to be heterologous to the Pythagorean, but it is still in the Pythagorean! ”

In fact, Zhao Hao also wanted to follow the 'oh', because it was the first time he had heard of the solution outside the textbook.

But considering his dignity as a teacher, he could only pretend to be a profound slight bow, saying that Hua Shuyang did a good job, and he was right.

Hey, there's no way, being a teacher for a genius disciple is boring, weak-hearted, and easy to hurt self-esteem......

"Now you understand? Why does the tutor only give propositions and not the derivation process, he is afraid of restricting our thinking. Seeing Zhao Hao nodded, Hua Shuyang's excited little face flushed, 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 continue to nod, in fact, he was just deliberately digging a pit and waiting for someone to jump in......

"Yes, this is all the hard work of the family teacher!" Wang Wuyang also nodded heavily and said: "This is the spirit of science, the quality that must be possessed by the family teacher!" ”
