Fei Zhixian and Ke Baotou looked at each other and looked at Qiu Wuhen in surprise.

Dianshi asked curiously: "Why is Mr. Qiu so sure that this person is half a head shorter than Mr. and smaller in stature? Has Mr. Qiu seen him before?"

Qiu Wuhen shook his head and said: "Of course I haven't seen him. If I have, I don't need to trouble you. I went to look for him directly. The reason why I came to this conclusion is because I surveyed the scene and found him emerging from the snow.

The hole and the two footprints left on the wall of the creek, I can calculate his height based on the distance between the two footprints, and roughly calculate his weight based on the size of his footprints."

"When he got out of the snow cave, he knelt and crawled all the way. In this way, the height of the snow cave was actually the height from his knees to his back. There is a calculation formula to calculate his height and weight. The most important thing is that he went to

When he crawled forward, his hands were covered with snow. When he crawled out, his palms also left several relatively clear palm prints on the ice surface. This kind of fingerprints is quite difficult to extract. Fortunately, I have a way.

I now have his fingerprints and can make the same identification. So as long as I can get the fingerprints of nearby villagers, I can find him."

Fei Zhixian raised his thumb and said to Qiu Wuhen: "You are really amazing. It seems that I have found the right person to be the master of punishment."

Then, Fei Zhixian said to Capt. Ke: "You just heard what Mr. Qiu said, and immediately sent people to search for people who meet the requirements along the villages near the creek. Take their fingerprints and palm prints immediately."

Send them here and tell Muramasa that these people need to be more closely supervised and no one is allowed to leave."

Ke Captou quickly agreed with his fists clasped, and immediately came out and left.

All that's left is to wait.

He came out of the Yamen and saw Linghu Zhi looking around from a distance, so he said hello.

Linghu Zhi saw him and ran over happily and said, "I'm looking for you! I heard that the magistrate has called you. How is it? Are you free now?"

"There is no free time. If you need my help with something important, I can always squeeze out the time. Tell me, what is it?"

"Teach us our homework! My dad said, you promised to tutor us. He is very busy recently, and I don't know what he is busy with. He doesn't have time to look at our homework. Can you look at it for us?"

Qiu Wuhen wanted to shirk it, but another woman came over, but it was Chuncan. She said, "If you help us with our homework, I can help you solve the case."

This sentence immediately piqued Qiu Wuhen's interest and said, "What case are you helping me solve?"

"Aren't you trying to solve the case of the mysterious deaths of those people in the County Yamen Academy?"

"Yeah, what's wrong?"

"You don't know, right? I have been studying in the county government school before. Those people are all my classmates. I know them all. I know some of their secrets. Maybe I can tell you and inspire you to solve the case.

!”

Qiu Wuhen said: "What do you know?"

"I know that Zhang Dalang was killed by a giraffe or a cheetah. The giraffe must have been hanged, right?"

Qiu Wuhen was stunned for a moment, because he didn't tell anyone, and the results of the on-site investigation and autopsy were not released at all. How did the Spring Silkworm know?

It seems she really knows something.

Qiu Wuhen nodded and said, "Okay! If you can help me, I can take a look at your homework. Let's go."

I followed the two women to the private school.

In the private school, Fei Wutong and Fei Wudan brothers saw him coming and quickly gathered around him. They handed their respective articles to Qiu Wuhen.

Qiu Wuhen took a look at it, and his head trembled. He was writing eight-part essays. Qiu Wuhen had never learned how to write eight-part essays at all. Even though his composition was relatively good, modern compositions were completely different from ancient eight-part essays.

It has nothing to do with cows and horses. They are all written in classical Chinese. It would be pretty good if he could read them, let alone give them guidance.

But at this point, it was unreasonable for him not to give some advice. Fortunately, he had already anticipated this outcome before coming, so he had already thought about the corresponding countermeasures in his mind.

He immediately smiled, nodded and said: "I think these two articles were done well, but I also told your husband that I can help you with your homework, but specifically what kind of tutoring did your husband ask me to do?

OK. I think it’s most appropriate for a gentleman to give guidance when writing an article. After all, my views may not be the same as your husband’s. How about not doing this and I’ll teach you something else that your husband may not know how to do. So that’s my promise.

He did what he set out to do.”

Linghu Zhi blinked her big eyes, looked at Qiu Wuhen curiously and said, "You still have something our husband, no, my father doesn't know? What is it?"

Qiu Wuhen said: "Let me ask you, what is nine thousand nine hundred and ninety-nine divided by one hundred and twenty-three?"

One by one, they shook their heads and said, "We don't know how to do this. We only know addition and subtraction. The teacher said that it's enough to learn addition and subtraction. We don't need it in daily life. We're not specialized in arithmetic, so there's no need to learn all that nonsense."

"Why is this called Laoshizi? Let me tell you, mathematics is both a technology and a way of thinking. If you learn mathematics well, you can hone your brain and gain strong logic. A logical thinking ability, because it

There is a rigorous derivation process, and if you learn these derivation processes, you will be able to have keen observation and dynamic measurement skills."

"Do you know why I solve crimes? Why can I be keen to discover problems and deduce a possible result based on a certain problem, and find the murderer? It's simple, because I can do arithmetic. I have learned arithmetic since I was a child, and I am better at it, so

I have a brain that is good at reasoning and summarizing, and that’s the key.”

"It will also be of great help to you if you learn arithmetic. For example, he can help you extract arguments from several arguments, and then use your arguments to demonstrate and finally draw your conclusion. This process is also

Those who need logical reasoning, and mathematics can help you, won’t this provide you with guidance?”

The two girls looked at each other: "Really?"

Qiu Wuhen shrugged and said, "I'm telling you, these are very important knowledge. It doesn't matter if you don't want to learn it. But I can't teach you other things. If you don't want to learn it, I'd better go to your husband."
