There are large pools, tall trees and big stones in the square. These are props prepared in advance by Yun Yao and can be used later.

"Dare you ask what the name of a Yue girl?" Mo Zi bowed to Yunyao and asked, very polite. He was obviously asking for advice and answers sincerely.

Yunyao is not a Yue girl, but she was too lazy to explain, so she said, "I have seen a giant, my name is Yunyao."

Mo Zi remembered it and asked, "The three questions of Zhucheng 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 is the question of the height of the tree. Our Mo family has the skills of a ladder. They can climb the city wall and reach the top of the tree. When standing on the ladder, you can use a rope to compare with the tree. As long as you measure the length of the rope, you can know the height of the tree."

The Mo family disciples are still very proud because the cloud ladder is the high-tech of this era, and most people cannot understand the beauty of the cloud ladder.

Yun Yao thought it was true, and she was not surprised. After all, the Mo family is famous for being good at defending the city in the future, so it is normal to know these high-tech. However, this method is still too troublesome and has a large error, so she said, "Why do you have to do this?"

Mo Zhai, who had thick eyebrows and big eyes, was very interested and thought to himself that there were other solutions. So he saluted and said, "Please ask the Yue Girl to solve the problem." With a wave of his hand, it seemed as if he was saying that you should start your performance.

Yun Yao brought everyone to a standing tree and said, "For example, this wood is a big tree." This metaphor is not difficult for the Mohist school.

"I can draw the height of the standing wood based on the shadow." Yunyao didn't keep it a secret and ordered Simei to operate it directly: "Xi Shi, Zheng Dan, you go and measure the length of the shadow of the standing wood." "Xia Ji, Nan Zi, you put the ruler here and measure the length of the shadow of the ruler."

When the four beauties started to operate, Yunyao smiled slightly with his hands in his arms.

Mozi looked at the four people's actions seriously, remembering these steps in mind, and could not see the mystery for a while.

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

After all the three data were measured, Yunyao wrote an equation in the sand table with a slender wooden pole, and finally calculated it to find the height of the standing wood.

"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 high, it is fine. As long as it is under the same sun height, this equation is true." If someone measures the shadow of the tree in the morning and the ruler in the evening, it will definitely not work.

Mo Zi applauded and exclaimed: "It's amazing, it's really amazing." He admitted that Yun Yao was right. Although he didn't understand the principle, his experience and intuition told him that this method was feasible.

The Mo family disciples behind also nodded. They were all experienced craftsmen and must have been exposed to similar triangles. Knowing that the two sides are similar, the proportion of the other side will definitely not change.

They were all very happy and couldn't help but feel a little admiration for the Yue Girl, and they were even more looking forward to how the Yue Girl answered the following two questions.

The second question is also simple, Cao Chong calls it a symbol.

There was a shrinking boat in the large pool. Yun Yao demonstrated that he placed the stone on the boat and marked the waterline of the boat. Then he removed the big stone and replaced it with a small stone, and stopped when the waterline was the same.

"It's amazing, it turns out that I can use the draught of the boat. I see boats coming and going in Zhuhe every day, why didn't I think of using the boat to make a scale?" Mo Zi exclaimed that he had actually seen so many boatmen on the edge of Zhuhe, and he should have thought of the method of boat scales.

"I admire you." Seeing Yun Yao solve two problems in a row, Mo Zhai was convinced.

The four beauties behind Yunyao almost laughed out loud, thinking that these questions were all produced by Yunyao herself, and she just took the exam by herself. Mo Zhai admired Yunyao so much and was simply cheated.

Yunyao, a god in the Heavenly Court, does not need to deceive mortals at all. If she was asked to say something herself, she would definitely think that this was an inspiration for the giant. How could it be said that it was a fraud? Can a liar teach victims so much knowledge?

Of course, Yun Yao appeared here entirely because of the superiority of gods. Mortals have to wait a hundred years later, or even a thousand years later, and they have to wait until the words of the scholars are practiced and tempered and proved to be correct before they can be accepted happily. Gods and immortals locked on them before the appearance of the scholars and used them to improve their cultivation. The choice of immortals is ahead of human experience.

Therefore, it is difficult for mortals to understand what the immortals do, and Yunyao doesn’t know how to explain it. After all, she is just a half-baked immortal, and there are still many things to improve.

"Now there is only the last question left." Mo Zhai looked at Yunyao expectantly, waiting for Yunyao to answer.

But Yunyao stopped and said, "If I can answer the last question, can we join the Mohist school and become the Mohist?"

Mo Zhai didn't expect that the other party had such a request and became embarrassed. The reason for the dilemma was that Yun Yao was a woman, and if they were men, Mo Zhai would not ask for it.

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

Mo Zhai agreed that this is the case. However, these five Yue women mastered the techniques that the Mo family had never mastered. He had a loving talent, but it was difficult for them to surpass the vast crowd of people in the world, so he was struggling in his heart.

The Taoist Lingbao, whose pseudonym was Mo Wei, said: "Since we want to oppose Confucianism, then we who support Confucianism should oppose it. Confucianism does not accept female disciples, so we Mohist school should accept it. Moreover, women weaving cloths and seeking the world are also very skillful."

Yun Yao couldn't help but glance at the Taoist Lingbao and found that he had changed a lot. Unexpectedly, he had already produced a Taoist foundation in a short period of time when he joined the Mo family. It seems that after Yan Hui, Taoist Lingbao also had the opportunity to return to the Xuan Realm.

However, Yunyao was not very clear about why Taoist Lingbao suddenly spoke for him. Could it be that he was the cause and effect of smuggling through himself?

This is true. Although Yun Yao and Taoist Qingxu are the most familiar, Ling Bao and others also came through Yun Yao, so this cause and effect must be returned.

Mo Zi fell into silence, and the other disciples had different expressions. They obviously couldn't accept Lingbao's suggestions and were reluctant to let the woman enter the Mo family.

Xia Ji smiled secretly, thinking that Yunyao would help the man speak, but in the end she was rejected by the man? Women should look like women, and should aim to eliminate men and not dream all day long. She wanted to see how she would make a decision if Yunyao's plan failed.

Xi Shi and Zheng Dan looked at each other. It was their profession to seduce men with beauty, but it would be a bit beyond their imagination to compete with men in the field of men. And they didn't think men would really accept women who were better than themselves.

Yunyao saw Mo Zi's entanglement and said, "Since you love each other, why are there any difference between men and women? Is it true that men are the property of heaven, and women are not? Nuwa created people to distinguish men and women, and women can hold half of the sky."

Mozi was speechless, and Yunyao used the theory of love to break Mozi's inner hesitation in a loud manner. If Mozi did not accept them, it would be that love both love and flaws, but only love both men and women, so how could he love the world?

There is a difference between men and women, a difference between old and young, and health and disease. If you can be picky about both sexes, then the system of sexes will eventually fall apart.

Moreover, Mo Zi has just established the idea of ​​"Director Love and Fighting", and is still an idealist, so when he heard Yun Yao say this, he realized that he must set an example, which determines whether the Dire Love and Fighting can continue.

"As long as you can solve the third question, you are disciples of the Mo family." The giant said loudly, not repentance.
