Others asked Sun Qilang to do the various novel facilities in Xu Ping's family if they wanted to learn. With this, he met many people and made a lot of money. Yan Su naturally knew him. Not only did he know him, he also made things with him.

Sun Qilang stepped forward to see the gift and took this opportunity to sit on the lower stool.

Today, when he was about to meet the guests, Sun Qilang changed into a public uniform. But for some reason, Sun Qilang felt uncomfortable when he wore this clothes on his body. Perhaps he was just a hard-working person and couldn't enjoy them.

Several people sat and talked, and before they knew it, the sun was rising, and Chu Yan and Jia Xian finally arrived.

The two brought a boy over, named Wei Pu, who was eighteen years old and looked like a honest boy. However, his eyes looked a little strange and he kept squinting, as if he couldn't open it.

After Jia Xian introduced it, I realized that this young man was a genius of arithmetics, especially his ability to be mentally arithmetic. No matter how complicated it is, the addition, subtraction, multiplication and division are, as soon as others say it, they can figure out the answer in their minds.

Xu Ping made a telescope and placed it in the Sitianjian. He obtained a large amount of data that could not be observed before. The existing personnel could not cope with it, so he sought talents from all over the world. Knowing that the military farmer of Chuzhou, he recommended this person.

Wei Pu was born in a poor family, but he was very talented in mathematics. He would never forget any such books after reading them once. However, in this era, he did not advance to mathematics. No matter how talented Wei Pu was, he could only stay in the countryside.

When he arrived at Sitianjian, Chu Yan was shocked when he saw it. He brought it with him and taught him all his knowledge. Xu Ping wanted to find new timer equipment for talents. If he succeeded, it would be a contribution. Chu Yan then consulted Jia Xian and brought the young man with him.

Although making new watches was Xu Ping's personal behavior and he was responsible for all the expenses, this kind of instrument had a great impact on the country and was really dedicated to the court. Naturally, there would be rewards and those who participated would also give merit.

Since ancient times, China has always emphasized the unity of man and nature. It is extremely important to obtain the time of nature and is by no means comparable to the standard time set by later generations.

Xu Ping looked at the teenager with his eyes blinking constantly, and it seemed a little weird. He moved his heart and asked him: "It seems inconvenient to see your eyes, but I wonder if you have some eye disease?"

Wei Pu stepped forward to salute: "Reported to the officials who are young, I am eager to study since I was a child. Whenever I get a book, I can't rest after reading it. I save money and buy oil to light a lamp to read the book. After a long time, I think I am so smoked that I have such an eye disease. I am far away from it on weekdays and can't read anything."

This is not smoked. It is obvious that I often read and write in the dim light, and myopia is myopia. The calligraphy in this era is printed with large characters and I am used to holding it in my hands. There are not many people with myopia. As far as Xu Ping knows, only Ouyang Xiu knew so many scholars, but only Ouyang Xiu had mild myopia, which did not affect his daily life. Wei Pu was actually the first severe myopia he saw in this era.

In Xu Ping's previous life, for many people, myopia glasses almost had to be carried with them. Once they took off their glasses, life was simply impossible to pass. In this era, reading glasses were much more useful than myopia glasses. Xu Ping made reading glasses to sell them in Sansi Shop, but myopia glasses never thought about them.

Wei Pu looked at Xu Ping, his eyes narrowed into a line, and he kept blinking.

This is really a bit unsovereign. Chu Yan, who was on the other hand, was afraid that Xu Ping would be unhappy, so he hurriedly said, "When the child is in good health, but his eye disease is difficult to treat. He sees people like this, otherwise it will be difficult to see clearly. Don't be surprised by waiting for the punishment."

Xu Ping smiled and said, "It's okay, I'm also a patient, I know that I'm having troubles with illness. However, this kind of eye disease may not be impossible to treat. Think of a solution in the future."

Chu Yan responded, but didn't take it to heart. Wei Pu's eye disease had no idea what the disease was. He had found several well-known doctors to see it, but he couldn't tell where the disease was. How to treat it?

Xu Ping didn't say it out loud. He was not sure that Wei Pu was severely myopia. After the myopia lenses were made, he asked him to try it. He could polish reading glasses, and the craftsmen in the glass business could polish myopia glasses. However, looking at the degree of myopia in Wei Pu's eyes, I don't know what thick myopia lenses used would be.

Because there was another person named Guo Zi not here, and he was not busy talking about the serious matters, Xu Ping casually gave a few questions to test Wei Pu.

Xu Ping didn't care much at first. In this era, he was proficient in mathematics, but due to the limitations of the times, he solved some simple mathematical problems. As for Wei Pu, Xu Ping just thought that he was just calculating faster than others.

Unexpectedly, adding and subtracting, Xu Ping came out of thousands of digits. Wei Pu still lowered his head and thought about it, and immediately gave the answer.

It’s okay to add or subtract, but there are no various quick calculation techniques in this era, and Wei Pu can even shout the correct answer in one word.

The more Xu Ping listened, the more shocked he became. Did he really meet a genius in arithmetic today? He didn't give up and simply didn't take the exam of addition, subtraction, multiplication and division, and asked him some simple equation questions. Traditional arithmetic books mostly use examples to explain mathematical problems, which are the application problems when Xu Ping was studying in his previous life. In this kind of example, equations are often used, which is common.

When Xu Ping asked the question of the one-element equation, Wei Pu immediately gave the answer.

Finally, Xu Ping simply asked some problems with the quadratic equation of the quadratic equation. Wei Pu was stumped at once, lowered his head and thought for a while, and tried to report a number.

Xu Ping's mental arithmetic ability is only average. He can still calculate the answers in his mind for the first equation, but he can't even make the answers in his mind for the quadratic equation. He was just a difficult task. Wei Pu tried his limits, but he didn't expect he could still give the answers.

Seeing Wei Pu blinking his eyes and looking at him seriously, Xu Ping was really embarrassed. He couldn't judge whether the answer was right or not.

Looking up, seeing Yan Su, Chu Yan and Jia Xian were also looking at him seriously. Xu Ping smiled embarrassedly: "I am not good at mental calculations. I still have to calculate whether it is right or wrong."

Yan Su breathed out, thinking that Xu Ping had made such a state of diligence.

Chu Yan brought a plan with him, and he was the guy who was eating, so he never left him. He took out the plan and placed it on the stone table. In a short while, the answer was found.

Although Xu Ping is not proficient in calculations, he can still use it now. He glanced at the table casually and looked up at Wei Pu in front of him, his face had changed.

Even the quadratic equation of a single element can be calculated in a short time. What kind of monster is Wei Pu?
