Huang Mingyu said with a smile: "Naturally, this old man also knows. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ”

Cheng Buchou and Huang Mingyu sang and harmonized like this, and everyone at the scene was shocked. Even Zhu Changyuan, who was standing next to him, was full of respect for Cheng Buchou's great-ancestor.

The person who can create an abacus to calculate the prescription is naturally an extremely smart person, Cheng Buchou actually said that the abacus prescription is just one of Cheng Dawei's stunts, and it can't help but make people guess: What is his other stunt?

Naturally, there was someone next to him who couldn't help it, and asked Cheng Buchou: "I don't know what is the other unique skill of Cheng Gongzi's great-grandfather?" ”

This time, without waiting for Cheng Buchou to speak, Huang Mingyu next to him replied on his behalf: "Mr. Cheng's other unique skill in the world is to measure the scooter. ”

"Measuring the scooter, what's that?"

Someone asked puzzled.

There are more and more people gathered around, and there are a few people who know how to count, especially the abacus Mr. Abacus in the shops next to him, who basically knows that the abacus prescription was invented by Cheng Dawei. But no one knows what this "measuring scooter" in Huang Mingyu's mouth is

Cheng Buchoi smiled slightly and said, "When you Zhang Ge Lao Zhang Juzheng is implementing a whip law to measure the land of the whole country, my great-grandfather will be in charge of it. He saw that the people were working too hard to measure the land with ropes, and it was inefficient, so he meditated hard, and finally got inspired by the ink fountain and invented a thing that could quickly measure the land, which was this measuring walker. ”

While speaking, Cheng Buchou demonstrated on the spot, and roughly explained the shape and use of the measuring scooter.

When Zhu Changyuan heard this, he suddenly realized, what is this special thing called measuring scooter, isn't this just a big tape measure?

However, being able to start from the actual needs and meditate hard to figure out this thing, Zhu Changyuan admired Cheng Dawei from the bottom of his heart.

Everyone chatted together for a while, and Cheng Buchou said goodbye to everyone and said, "Everyone." In the next urgent matter, not much accompaniment. Farewell"

He is gone, and Huang Mingyu is gone.

Zhu Changyuan swayed and continued to go shopping with the broken captive.

Cheng Buchou hurriedly returned home, not caring about the smell of dust all over his body. Walk straight to my father's study.

"Father"

The door of the study was open, but he didn't dare to rush in, the contemporary head of the Cheng family was called Cheng Shuzheng, and he was a serious and even more serious person.

Naturally, the rules of the more serious people are also greater. It is required that the children in the family must understand etiquette and etiquette.

"Come in." A majestic voice came from the study, Cheng Bu got dressed and went in, saw his father admiring a landscape painting, and said, "Father."

"Yes." Cheng Shuzheng raised his head and glanced at Cheng Buchou, and beckoned to him in a comfortable mood, "Buchou, come over and see whose painting this is?" ”

Cheng Buchou walked into his father's desk, looked at it, and was suddenly surprised, and even his voice changed. said: "Father, this, this is Wang Shimin's painting?" ”

"Hmm" Cheng Shuzheng nodded with a smile and said, "Your eyesight is good, it is the prince's masterpiece." Saying proudly, he read the inscription above: "The clouds are outside the sky, the clouds and flowers are the flowers on the stone, and the people watch the sea and the moon, and the sun is suddenly oblique." ”

On this landscape painting, there are mountains and clouds, the east moon and the west sun, and the artistic conception is very lofty.

If that's all there is to it, it's ordinary, and these paintings are just backgrounds. The theme is a magnificent picture of the sea, with a sailboat painted in the upper middle, and a bright moon hangs high above the sailboat. It is suddenly vast and profound, and the artistic conception is far-reaching.

"It's a good painting, it's really a good painting, I don't know how my father can get the true handiwork of the prince?" Cheng Buchoi, a half-person who doesn't know much about painting, can't put it down, let alone his father, who thinks of himself as an elegant man all day long.

The Cheng family has been a merchant for four generations since the throne of Cheng. There is no fame in the body, if there is anything different from ordinary businessmen in this merchant family, it is that the people of the Cheng family are proficient in mathematics.

This is also their family's glorious tradition, and naturally it cannot be easily discarded.

Although this Cheng Shuzheng did not have fame, he regarded himself as a literati all day long, and he had intersections with many celebrities at that time, especially those who were already respected in contemporary times.

For example, Wang Shimin of Taicang, a generation of Confucianism in Shaoxing Mansion, a generation of Confucianism in Shaoxing Mansion, and Liu Zongzhou of the Ministry of Industry.

"It's a long story" Cheng Shuzheng was in a good mood today, and couldn't help but chat with his son a few more words, and said: "The prince and I are in the same year, and we are from Taicang, Jiangsu. ”

Seeing Wang Shimin's paintings, Cheng Shuzheng's attitude and voice towards his son's speech were much gentler.

Cheng Buqiao bowed down and said, "Father, the child has one more important thing to report." ”

"Say" Cheng Shuzheng sat on the stool again, and couldn't put it down, picked up Wang Shimin's painting and rubbed it, not taking Cheng Buchou's words to heart at all.

"Yes, father." Cheng Buchou said: "Zhu Changyuan, the director of the Ministry of Industry, threatened to hold a lecture in the Yamen of the Ministry of Industry the morning after tomorrow, which is said to be to teach the great art of cutting circles. ”

"Hmm." Cheng Shuzheng responded absentmindedly, as if he hadn't heard what Cheng Buqiu was saying at all, paused for two seconds, and finally came back to his senses, suddenly got up from the chair, and asked in a serious voice, "What did you just say?" ”

"Father, the child said that on the morning after tomorrow, Lord Zhu, the director of the Ministry of Industry, gave a lecture in the Yamen of the Ministry of Industry, saying that he was teaching the great technique of cutting circles, and invited people inside and outside the capital to listen to the evidence."

Cheng Buchou repeated what he had just said.

Cheng Shuzheng looked up in amazement, looked at his son incredulously, stood up, walked in front of him, looked left and right, and said, "Bu Chip, don't you have a problem with your brain, do you believe this kind of thing?" ”

"Circumcision? Still giving lectures? Cheng Shuzheng smiled, smiling very gently, but also very disdainful, "Ancient and modern times have been going back and forth for more than a thousand years, do you know how many famous masters have broken here?" Did you know that your great-grandfather, my grandfather, tried to solve this age-old puzzle, but in the end it was nothing? ”

"What do you think can solve a problem that your great-grandfather can't solve?"

In the bones of the Cheng family, there is still this bit of arrogance.

Of course, they also have the capital of pride, and their ancestor Cheng Dawei is indeed a great master of mathematics.

"Father, this matter is true, now everyone is talking about this matter on the streets, and the child does not dare to deceive him" Cheng Buchou's serious appearance did not impress Cheng Shuzheng at all.

"It's just a rumor, don't pay attention to it." Cheng Shu Zhengfu sat at the table again and admired his landscape paintings.

"Father"

"Say no more." Cheng Shuzheng is willing to listen to his son's explanation.

However, he is destined not to have the opportunity to continue to appreciate the "Canghai Map" made by the contemporary master Wang Shimin.

A subordinate tiptoed to the door, bowed and saluted, and said, "Master, Master Li Jili, a member of the Ministry of Labor, came to the mansion and asked to see the master." ”

"Huh?" As soon as he talked about the Ministry of Industry, the people from the Ministry of Industry arrived, Cheng Shuzheng was stunned for a while, then put the picture scroll up and put it away, and said, "I'll go meet him." ”

"No need Brother Cheng, I've already arrived." Li Ji walked from the courtyard to Cheng Shuzheng's study with a smile, and said, "I hope Brother Cheng won't blame him for being abrupt." ”

"Where, where the adults can come, it is the fluffy and shining." Cheng Shuzheng invited Li Ji into the guest room and took a seat.

Li Ji said: "If you have nothing to do, you will go to the Three Treasures Palace, and when you come here, you will ask Brother Cheng to come out for something." ”

"Speak, Adult"

"Please forgive me for taking the liberty of taking the liberty of the next day, on the order of Lord Liu, please invite Mr. Cheng to come to the Yamen of our Ministry of Industry the day after tomorrow, when the head of the Yamen, Lord Zhu, will give a lecture and teach the great art of cutting the circle. I asked the gentleman to go and help with the calculations. ”

"What?" Cheng Shuzheng almost jumped off his seat, and secretly said that there are really people who don't know the height of the sky and the thickness of the earth, and dare to open the hall in public, isn't it crazy.

In modern times, it's like there's a class about aliens, and it's unbelievable.

"Brother Cheng." Li Ji smiled and said, "Please also invite Brother Cheng to come at that time." ”

Cheng Shuzheng shook his head and said, "It's not that I don't give face to Lord Liu, it's true, what Lord Zhu doesn't know the height of the sky, and he actually talks about the great art of cutting the circle." There is nothing you can do about it. ”

"Hey" Li Ji said: "Brother Cheng, don't refuse first, why not deign to be honest, although I am not very optimistic about Lord Zhu's great technique of cutting the circle, but I am full of curiosity." ”

"Besides, this is Lord Liu Zongzhou and Lord Liu personally asked me to invite you," Li Ji said again.

"Oh. Lord Liu is invited, dare to disobey his fate? "Cheng Shuzheng just heard Li Ji say that Lord Liu, and thought it was Liu Zunxian, the secretary of the Ministry of Industry, but he didn't expect it to be Liu Zongzhou who came to invite.

To be honest, in Cheng Shuzheng's eyes, a hundred Ministry of Industry Shangshu is not worth one Liu Zongzhou.

Because Liu Zongzhou is a great Confucian in the world, his protégé is full of peach and plum.

Masters of the world

"Okay, since Brother Cheng agreed, there are important things to do next, so I won't stay longer." Li Ji got up to say goodbye, not that he really had any important business, but that he had a general friendship with this Cheng Shuzheng, and he didn't have much to say.

Moreover, he is a dignified member of the Ministry of Labor, and he really looks down on this businessman's fake Taoism.

After the "father" sent Li Ji away, Cheng Buchoi bowed his hand to Cheng Shuzheng beside him and said: "The day after tomorrow, Master Zhu of the Yamen of the Ministry of Industry will give a lecture in the hall, do you really want to go over to help?" ”

Cheng Buchou asked, not because he cared about his father, but because he wanted to go. According to the strict family rules of the Cheng family, if the father commits something taboo and does it for his son, the consequences will be very serious.

"Go" Cheng Shuzheng said: "Why don't you go?" The two masters of my Cheng family have passed on their skills, the same is the abacus and the other is the measuring scooter, I have to bring it over, just to take this opportunity to let the world see it"

"Cut round? Hmph, this kind of arrogant and ignorant person, I can't say that I have to prepare some good looks for him" to be continued.
