There are large pools in the square, tall woods, and large stones. These are all props that Yun Yao prepared in advance, and they will be used later.

"Dare to ask what is the name of the Yue Nu?" Mozi saluted Yun Yao and asked, very politely. Apparently genuinely seeking answers.

Yun Yao is not a Yue girl, but she didn't bother to explain, so she said: "I've seen Juzi, my name is Yun Yao." ”

Mozi remembered, and he asked, "Zhu Cheng's three questions are really interesting, but I only solved one question, and I hope to ask for advice." ”

"I wonder which question the giant answered?"

Mozi said: "The first question about the height of the tree, our Mo family has the skill of the ladder, you can climb the city wall, you can reach the top of the tree, you can use the rope to compare the height of the tree when you stand on the ladder, as long as you measure the length of the rope, you can know the height of the tree." ”

The disciples of the Mo family are still very proud, because the cloud ladder is the high technology of this era, and ordinary people can't understand the wonder of the cloud ladder at all.

Yun Yao thought to herself that this was the case, she was not surprised, after all, the Mo family was famous for being good at defending cities in the future, and it was normal to know these high-tech. However, this method is still too troublesome, and the error is still large, so he said: "Why bother. ”

Mo Zhai, who has thick eyebrows and big eyes, is interested, is there any other solution to the secret path? So he saluted and said, "Please also ask the Yue Nu to solve the problem." "With a wave of your hand, it's like saying please start your show.

Yun Yao led everyone to a standing tree and said, "For example, this wood is a big tree. This analogy is not difficult for the Mo family.

"I can figure out the height of the standing timber from the shadow." Yun Yao didn't sell Guan Zi either, and instructed Simei to operate directly: "Xi Shi, Zheng Dan, you go and measure the shadow length of the standing tree." "Xia Ji, Nanzi, you stand here with a ruler and measure the shadow length of the ruler."

When the four beauties operated, Yun Yao smiled slightly.

Mozi watched the movements of the four of them seriously, keeping these steps in mind, and couldn't see the mystery for a while.

In fact, it is very simple, the ratio of the ruler to the shadow of the ruler is equal to the ratio of the height of the wood to the shadow of the wood, and the length of the ruler, the shadow of the ruler, and the shadow of the wood can be easily measured, and finally the height of the wood can be found.

After all three data were measured, Yun Yao used a slender wooden pole to write an equation in the sand table, and finally calculated the height of the standing tree.

"So as long as we know the shadow length of a tall tree, we can also use this method to solve the height of the tree, even if the tree is tall. As long as it is below the same day height, this equation holds. "If someone measures the shadow of a tree in the morning and the ruler in the evening, it will definitely not work.

Mozi clapped his hands and exclaimed: "It's wonderful, it's really amazing." He admits that Yun Yao was right, and although he didn't understand the principle, experience and intuition told him that this method was possible.

The disciples of the Mo family in the back also nodded one after another, they are all experienced craftsmen, they must have all come into contact with similar triangles, and they know that the two sides are similar, so the proportion of the other side will definitely not change.

They were all very happy, and they couldn't help but have a trace of admiration for Yue Nu, and they were even more looking forward to how Yue Nu would answer the following two questions.

The second question is also simple, Cao Chong called the elephant.

There is a shrunken boat in the large pool, and Yun Yao demonstrates putting stones on the boat and marking the waterline of the boat. Remove the large stone and replace it with a small stone, and stop when the waterline is the same.

"Wonderful, it turns out that you can use the draft of the boat. I see boats coming and going in Zhuhe every day, why didn't I think of using boats as scales? Mozi exclaimed in surprise, but in fact, he saw so many boatmen on the side of the Zhu River, and he should have thought of the method of ship scales a long time ago.

"Admire, admire." Seeing Yun Yao solve the two questions in a row, Mo Zhai was already convinced.

The four beauties behind Yun Yao almost laughed, thinking that these questions were all made by Yun Yao herself, and she was testing herself. Mo Zhai admired Yun Yao so much, he was deceived at all.

Yun Yao, a Heavenly Court Immortal, doesn't need to deceive mortals at all, if she is allowed to say it herself, she will definitely think that this is an inspiration to the giant, how can it be said to be a lie? How much can a scammer teach his victim?

Of course, Yun Yao appeared here entirely because of the superiority of the immortals. If a mortal wants to accept the power of the hundred schools of thought, he must wait for a hundred years, or even a thousand years, until the words of the sons have been tempered and proven to be correct, before they can happily accept it. And the immortals locked down the hundred schools of Zhuzi before they appeared, and used Zhuzi to improve their cultivation. The choice of the immortals precedes human experience.

Therefore, it is difficult for mortals to understand what the immortals do, and Yun Yao doesn't know how to explain it, after all, she is only a half-hung immortal, and there are still many things that need to be improved.

"Now that's the last question left." Mo Zhai looked at Yun Yao expectantly, waiting for Yun Yao to answer.

But Yun Yao stopped and said, "If I can answer the last question, can we also join the Mo school and become Mo scholars?" ”

Mo Zhai didn't expect the other party to have such a request, and he was immediately embarrassed. The reason for the embarrassment is that Yun Yao's gender is female, if they are men, Mo Zhai can't ask for it.

"Because we are women, it is inconvenient for the giant to agree?" Yun Yao was not angry, and asked with a faint smile.

Mo Zhai acquiesced, that's it. However, these five Yue girls have mastered the technology that the Mo family has never mastered, and he has the heart to love talents, but it is difficult to defeat the world's long mouths, so his heart is entangled.

A Lingbao Taoist with the pseudonym Mo Wei on the side said: "Since we want to oppose Confucianism, then we should oppose what Confucianism supports." Confucianism does not accept female disciples, so our Mo family should accept it. Besides, women's weaving, the world asks, is also very skilled. ”

Yun Yao couldn't help but glance at the Lingbao Daoist, and found that he had changed a lot, but he didn't expect that he had already produced a Dao base in a short period of time after he entered the Mo family, and it seemed that after Yan Hui, the Lingbao Daoist also had the opportunity to return to the Xuan Realm.

However, Yun Yao didn't know why Lingbao Daoist suddenly helped him speak, could it be the cause and effect of smuggling by himself?

Indeed, although Yun Yao and Qingxu Dao are the most familiar with each other, Lingbao and the others are also smuggled through Yun Yao, so this cause and effect also has to be returned.

Mozi fell silent, and the other disciples had different expressions, obviously not quite accepting Lingbao's suggestion, and were not very willing to let the woman enter the Mo family.

Xia Ji looked at it and smiled secretly, thinking that she wanted Yun Yao to help the man speak, but in the end, she was not rejected by the man? Women should look like women, and they should aim to eliminate men, and don't daydream all day long. She wanted to see how Yun Yao would make a decision if her plan fell through.

Xi Shi and Zheng Dan looked at each other, if it was their profession to seduce men with beauty, but it was a little beyond their imagination to compete with men in the field of men. And they don't think that men will really accept women who are better than themselves.

Yun Yao saw Mozi's entanglement, and said loudly: "Since there is love, why is there a difference between men and women?" Is it true that men are the property of God, but not women? Nuwa creates men and women, and women can hold up half the sky. ”

Mozi was speechless, and Yun Yao used the words of love to break through Mozi's inner hesitation. If Mozi doesn't accept them, it means that love is defective, but he loves men and not women, so how can he love the world?

There are differences between men and women, between old and young, between health and disease, and if love can be picky, then eventually the system of love will fall apart.

And now Mozi has just established the idea of both love and non-attack, and he is still an idealist, so when he heard Yun Yao say this, he realized that he had to set an example, which determined whether he could go on with love and non-attack.

"As long as you can solve the third question, you are a disciple of the Mo family." The giant said loudly that he would not regret it.

Yun Yao bowed and said, "Then I will be ugly." ”
