Zhu Youxiao still doesn't know how much the one plus one question he issued today will have in the future Ming Dynasty, and even directly accelerated the historical process of the Ming Dynasty.

From then on, the development of science and industry in the Ming Dynasty was like a chicken blood. Under the leadership of Xu Guangqi's concept of how fast, how easy it is to save money and not take detours, the research level has risen step by step and the results have emerged one after another.

The Ming Taxation Department also achieved brilliant results. They gradually changed their routines and quoted the idea of ​​Sun Yuanhua, the first tax officer of the Ming Dynasty, that is, no matter how complicated your accounts are, as long as you have too much money, you have to pay taxes, even if you have robbed the money, you have to pay taxes!

This has led to the inexplicable forces in the future Ming Dynasty. They can be aggressive and arrogant when facing other government departments. However, they will be honest in the face of tax authorities and will become a bastard. They will have to hold back their farts and dare not make any noise.

However, at this time, Zhu Youxiao was still accepting this respectful look with a smile, seeing that this was the consequence of being sunk by me.

If he knew how much benefit his unconscious action brought to Daming today, he would have told outsiders very humbly.

That’s right! It’s all my credit. I’m afraid they will be in a period of confusion, so I specially gave them some profound ideological education. Well, don’t spread it outside, and don’t give me a positive image across the country. Be selfless, love the people as your son, and be harmonious with the ruler and the ministers. These are all insignificant things I should do, and I’m doing every day what I’m doing.

The first question tests mathematics, the second question tests psychology, and the third question tests Li Tianjing's logic.

The logic of taxation must be meticulous. Zhu Youxiao wanted to see how Li Tianjing's logic was, so he thought of a classic logic "mathematics" problem.

"There is a small village where fifty families live, each of which has a dog. One day, a mad dog appeared in the village. Everyone discussed together that they had to check the dog every morning. Once they found that their dog was a mad dog, they had to beat their mad dog to death that night. The families in this village all had the same ability, that is, they could see whether other people's dogs were mad dogs, but they could not see whether their dogs were mad dogs. And they could not tell others about the situation. So on the first day and the next day, no one in the village killed the dogs, but on the third day, someone in the village killed the dogs, so all the mad dogs in the village were killed. So how many mad dogs are there in this village? "

In fact, Zhu Youxiao is also looking forward to it. Tax work requires strong logical meticulousness. Therefore, if Li Tianjing cannot withstand this most important logical test, then he will not be competent for the director of the Daming Tax Deposit Office. In this way, he doesn’t know who to be the one who is going to be. This will cause a headache for himself. After all, there is no university or anything else now. Mathematics depends entirely on his own interests and hobbies.

Moreover, in this era when the imperial examinations were first and foremost, anyone who did not take the imperial examinations was a wrong way and did not need to pay attention to it. There were only a few people who were interested in learning mathematics, and they knew each other. Otherwise, why did Sun Yuanhua only introduce Li Tianjing to himself? It must be that he thought Li Tianjing could do math, but the deeper level must be that he could only find such a person.

Although there are a few foreigners who can do math, Zhu Youxiao is still very worried about such an important matter and he handed over such an important matter to a few foreigners. This may be equivalent to handing over one of the biggest secrets of the Ming Dynasty to others. But you don’t know what those foreigners think. It’s better to use your own people if you are unpredictable.

Li Tianjing wrote the thing on paper while listening to the question. To be honest, he had never seen anything similar to this question. It seemed to have hidden some profound meaning. It cannot be calculated using ordinary math. It requires the ability to reason, and this is what he is best at.

"Ha!" Zhu Youxiao yawned and was a little sleepy. He felt that Li Tianjing would definitely not be able to solve this problem for a while. Since that's the case, I'll go have a meal and don't worry about giving him three days. I thought I had solved it for two days back then, and giving him three days would already be very worthy of him.

So Zhu Youxiao raised his legs and prepared to go out to find someone to have a meal, but was stopped by Li Tianjing.

"Your Majesty has been unlocked!" Li Tianjing bowed to Zhu Youxiao confidently.

"What's the matter! You unlocked it!" Zhu Youxiao almost glared out his eyes. How long does it take, ten minutes? You told me that you solved it. Could it be to deceive me? How could it be? I just thought about it before I came up with the answer.

If you can solve it, I will sink myself!

Have you seen this winter? I dare to drill ice holes!

Just kidding! Haha! I will solve the problem later and see if I don’t throw you into the ice hole and wake up!

"Your Majesty, look! I will listen to the students explain it to you one by one." Li Tianjing calmly wrote down his problem-solving process on paper.

First of all, every villager knows that mad dogs must be in the village

Then the reasoning begins later. Let's assume that the villagers discovered that among the forty-nine families he observed, forty-eight families were good dogs, and only one was crazy dog.

Because the villagers cannot make assertions about their dogs, they will think that at least there is one mad dog, at most two.

Since this is the case, if the dog in the family is not a mad dog, then the dog in his family is a good dog in forty-nine families. If the dog in his family is a mad dog, then he is the camp of two mad dogs.

But he couldn't tell whether his dog was a good or a mad dog.

If his dog is also a good dog, he only saw that the dog was the only mad dog. Someone would definitely kill the dog on the first day, but no villagers killed the dog on the first day, so the number of mad dogs is not one but two.

In this way, villagers will kill dogs the next day, but no one will kill dogs the next day.

In this way, the number of mad dogs that reason will not be one or two

Then I can only continue to reason. Some villagers found that among the forty-nine families he saw, forty-seven of them were good dogs, and two were crazy dogs.

It was because his dog didn't know the situation, so he could only think that there were at least two mad dogs and three at most.

If there are two, then there are forty-eight families with good dogs, then your own family is a good dog. If there are three, then there are forty-seven families with good dogs, and your own family is a crazy dog.

Although he could not be sure whether it was two or three, he would infer that if it was two, then two people would kill the dog the next day, but no one would kill the next day.

Then there are three, which means that a villager already knows that his dog is a mad dog.

So on the third day, the villagers killed dogs, so there were only three.

Zhu Youxiao looked at Li Tianjing in a daze. What's going on?

I seem to be sunk. Is this?

How did he do it so quickly? How did this thing grow in mind? I...

I was not careful at that time, otherwise I would have done it faster than he did!

Yes, that's it!

"It's not bad, it's a little slower than I expected. You have to work hard. It's been so long for such a simple question. You still have to study and study with me. In a few days, I will give you some tax books and you can take a look."

"Okay, Sun Yuanhua, go and talk to the Ministry of Personnel, just say that Li Tianjing is the director of the Tax Deposit Department, a fourth-rank official! Okay, you all retreat, I'm a little tired." Zhu Youxiao felt that he had been hit a little and wanted to squat down and drink a bottle of happy water alone.

"Thank you for your grace!" Li Tianjing quickly thanked him. He finally got his Majesty's approval, but he still had to work harder. He didn't hear what Your Majesty said, but he was still far from it. He tried to catch up with His Majesty's success as soon as possible.

"By the way, the natural scriptures, I think you are still lacking in your calculations. I will leave you a small problem and go back to practice." Zhu Youxiao suddenly remembered something and said with a wicked smile.

The three of them went to the hotel and each paid ten cents, which was thirty cents a total of thirty cents. The waiter wanted to give the three people five cents a cheaper price, but because the three people couldn't share, he refunded one cent to each of the three people, and the remaining two cents was paid to the children himself. Later, the waiter thought that this would be equivalent to nine cents per person, which would be twenty-seven cents. If he added his two cents, it would be twenty-nine cents in total, which should be thirty cents. Then where would he go?

When Sun Yuanhua left the palace gate, he wanted to have a good drink with Li Tianjing, but when he turned around, he saw a lost person grabbing his head.

He kept shouting: "Where is there a penny left? Why is there a penny gone?"

"One penny...one penny..."

"Brother Sexual Ginseng! Brother Sexual Ginseng! What's wrong with you? This is how are you?" Sun Yuanhua looked at his eyes that were dull and full of energy and was a little scared. Why did this suddenly turn out to be the case? What happened? This is?

Could it be that he was possessed by evil spirits?

Looking at the blue sky outside the palace, Zhu Youxiao's lips curled up, and he was still fighting with me! I won't teach you a good lesson.
