Daming: I became Zhu Yuanzhang's eldest son

What he quoted was the pheasant and rabbit in the same cage algorithm proposed in Nine Chapters of Arithmetic. He thought that this algorithm was quite subtle, and it was far beyond the comprehension of Zhu Tao, who had no reputation.

I just wanted to humiliate him in this regard, who knew that Zhu Tao was not a vegetarian either.

"I said you kid, I guess you haven't graduated from elementary school, and you dare to call yourself invincible? The boys in my college can do calculations, can you still be worthy of my young master, who, you son of a bitch, you come and tell him the answer. If the answer is correct, I will give you a skewer to eat as a reward."

Goudan is a ten-year-old boy who usually attends classes in the school opened by Zhu Tao.

"Yes, Dean!"

He was not at all stage frightened, and stared straight at the invincible said.

"Such a simple linear equation in two variables, don't show it off, 48 pheasants, a rabbit, please come up with some difficult exam questions."

The one who was considered invincible almost dropped his jaw, clapped his hands and said.

"The old man has been calculating for several years before he can fully understand the problem of the pheasant and the rabbit in the same cage. You kid has studied for a few more years, and you are so smart. You are a prodigy. Would you like to go with the old man? As long as you have been trained for a few years , Guaranteed that you will go to the court hall to enter the court, and no one can compare."

Goudan showed his white teeth and laughed a few times.

"In the dean's school, I'm the stupidest bastard. Even an elm lump like you dare to call yourself a genius in the world. You learned your knowledge from your teacher, right?"

The invincible face turned into a big red cloth with shame, and hid behind Xu Ya disheveledly.

Xu Ya was not surprised by Zhu Tao's performance. If he couldn't handle such a small fight, what kind of genius would he be?

Seeing that Zhu Tao was about to ask her for exam questions again, she said very generously: "Brother Zhu, for the sake of fairness, it's up to you to come up with the next one."

As soon as these words came out, the cheerleaders around him cheered in unison: "Wow, Mr. Xu is a man of high integrity and integrity, which is admirable. This is a unique talent. The kid surnamed Zhu, you are still far behind!"

Zhu Tao turned a deaf ear to these arguments, and casually pointed to the nearby field.

"This land needs to be irrigated by people using water trucks. I have always wanted to drill a well here. Let's bet whoever drills the well is convenient and practical. Come first."

Among Xu Ya's friends, there are really some people who are good at construction. After discussing together, they immediately found a group of laborers. Everyone took tools. After a while, a well was dug out and built with bricks. up.

That's not to mention, there is also an orange tree on it for carrying water, which is quite convenient.

These people have been busy for a whole noon before it was done, which attracted infinite praise. Xu Ya looked at Zhu Tao proudly: "Brother Zhu, how about this equipment, my lord?"

Zhu Tao nodded, "This kind of water-lifting device is ingeniously conceived and very difficult, but it is very time-consuming and labor-intensive. Let me show you the water dragon in Zhujiazhuang!"

Tap water?

These famous equipment experts all opened their eyes wide: "What kind of weird thing is this?"

Zhu Tao said: "It just so happens that the fields on this side of the road also need to divert water. Old Tang, go and bring our water hose for irrigation. Once it's done, we can divert water and let's go back to eat!"

It took Xu Ya and the others a long time to dig a well just now, which is already extremely fast. Who knew that Zhu Tao was not ashamed to say that he would go back to have lunch after drilling the well. Doesn't this mean that a well can be drilled in about an hour?Is there such a bragging?

All the people burst into laughter, thinking that Zhu Tao would lose this time.

Who knew that Old Tang had gone, and soon he rushed over carrying a large iron pipe more than four feet long.

The diameter of this iron pipe is about two and a half inches. One end is connected with a forked iron pipe with a thickness of one foot, and the other end is shaped into a cone with densely packed small holes.

Several people erected an elevated frame, erected the iron pipes, and smashed them into the ground with a sledgehammer.

The soil here is soft, and within half an hour, the four-foot-long iron pipe had already been smashed into the ground.

There is also a small part on the iron pipe, which was quickly assembled. In the end, only a three-foot-long lever was exposed.

What Zhu Tao drilled is a very common pressurized well in modern times, that is, a piston pump. Since this thing originated in ancient Greece, it is also called Aristotle's well.

It was introduced to China in the early twentieth century, but no one had seen it in the Ming Dynasty. After all the work was done, Old Tang came over and saluted Zhu Tao respectfully.

"Young Master, the well has been dug."

Xu Ya was so angry that she almost jumped up: "What is this well called, how do you get water? How do you irrigate?"

Zhu Tao didn't talk nonsense, and directly told Old Tang: "Drain the water and go back to eat!"

I saw a servant carrying a bucket of water and pouring it into the pressurized well. Several people pressed it hard a few times, and water really came out of it.

Seeing that the water was pumped out with a slight pressure, everyone was dumbfounded: "This is simply amazing!"

At this time Zhu Di came out: "Cousin, can you use this kind of pressurized well anywhere?"

Zhu Tao smiled: "Of course, this kind of pressurized well can be used as long as there is a water source. Even if it is carried on the march and fight, it is very convenient to fetch water. It can be put away when not in use, and can be drawn out repeatedly when in use. Use it, it’s an artifact for fetching water.”

Zhu Di excitedly grabbed his hand and said loudly, "Tell me quickly, how many pressurized wells do you have? Our State Commercial Division purchases all of them!"

Seeing Zhu Di's expression, Xu Ya was at a loss. Although the pressurized well was ingenious, it was not enough to conquer her. She also prepared the third test questions.

On the other hand, why did she and the third brother come forward? Isn't it the prince's brother-in-law?But the victim didn't pursue the responsibility, so what's the point of arguing with the whole group.

Seeing that Zhu Tao turned to talk about purchasing with Zhu Di, he had no time to take care of her, so he said: "Today's competition is tied. But don't get too carried away, my son will come again!"

After uttering harsh words, he was about to lead people away, but was stopped by Zhu Tao, who said, "Why, brother Zhu, do you still want to keep food?"

"I miss you too much."

Zhu Tao said to Old Tang: "Let's not keep that person, since they have suffered enough, let's let them go."

After hearing Zhu Tao's order, Old Tang agreed, and after a while, he brought all the second-generation ancestors who came to the village to make trouble.

These people saw that Zhu Yuanzhang and his son were here, and no one dared to do anything wrong, and they came to Zhu Tao with their heads downcast.

Zhu Tao had nothing to say to them, and waved his hand: "Stop wasting food here, go back to each house and find your own mother, don't let me see you again next time, or I have to educate you."

Xu Zengshou was dejected, and Xu Ya walked over. He didn't go far, but was stopped by Old Tang, who rolled his eyelids, "Do you want to go back on your word?"
