Take a plane to the Ming Dynasty

Chapter 161 Sensation ([-])

"Buy, buy the duplex of Wangjiang Water Park, buddy, you are sure, in case you can't get a loan..." Erdanzi Liu was interrupted by Zhu Changyuan before he could finish speaking.

"Don't think about it so much, you go to your brother-in-law for help, go to the bank to get a certificate of repayment ability, and buy it with confidence."

The matter of buying a house was finalized, and a stone in Zhu Changyuan's heart was relieved, and he thought to himself: Mom and Dad, my son can't be by your side all the time, so I can only do my filial piety like this.

After the two talked, they left the western restaurant.

Zhu Changyuan came near the store in Liu Guang's Audi and asked Liu Guang to go home by himself. It would be boring for him to wander around the street alone.Suddenly, I saw a photo studio not far away with the lights still on, thinking that I bought an old-fashioned camera there some time ago, and a little girl there misunderstood that she was a robber, so I couldn't help but smile.

He lifted his foot and walked in.

Of course, I didn't go in to flirt with other girls, but I took a lot of photos of Lana and Yu Min in the capital last time, and I couldn't develop them myself, so I sent them over to the store for help.

Pass the film to the girl, pay the money, and the matter is perfectly resolved.Then I reached out to find a taxi by the side of the road and took a taxi home.

When I got home at night, my parents were still up and waiting for me.

Zhu Changyuan was a little guilty, but he didn't dare to tell his parents about buying a house face to face, otherwise they would give him a long-winded talk.

Drinking tea and chatting with my parents, the time flies by.

Under such an extremely warm atmosphere, Zhu Changyuan almost didn't want to go back!But if you don't go back, you can't do it. If you don't have contribution points and stay in the modern society, you will be forced to go back to the parallel world sooner or later.

Besides, the two wives will be sent back to Riyue Island in the next two days, so they can't stay at home all the time.

We chatted until after eleven o'clock in the evening. My mother was afraid that her baby son would be too sleepy, so she said, "Go to bed, your dad and I are tired too." In fact, it's not that they are tired, it's obviously because they are worried that they are tired .

Zhu Changyuan naturally understood in his heart, nodded, and returned to the bedroom very obediently, looking at the wall clock above his head, it was almost twelve o'clock.

"Oh! I have to go back."

After waiting for a while, after hearing no movement from his parents' room, Zhu Changyuan began to travel.

Open the system interface, click to return to the parallel world, and return to the original location by default, which is a hidden place not far from me.

With a flash of white light, he returned to the parallel world, walked unsteadily to his door, crept upstairs, and went to his bedroom to sleep. This day was really tiring.

There was a five-day holiday around the Mid-Autumn Festival, and he didn't have to go to the Yamen to guard the next day. For Zhu Changyuan, this was a rare big sleep. He slept until the sun was high and woke up naturally.

One word "cool!"

Two words "so cool!"

"Ha." He yawned for a long time, then began to wash up, and went downstairs after finishing, only to find that his two wives were not at home.Seeing Polu cleaning the yard, he asked, "Where's Madam?"

Polu said: "Morning, my lord. The wives took their maidservants out to buy things. Elder sister Su Ya said that she will go to the island tomorrow and she needs to buy more things."

Uh, Zhu Changyuan understands, it seems that the two wives have set the return date to tomorrow, so there is nothing wrong with that.

After simply eating a little breakfast, Zhu Changyuan also walked out the door with square steps, and brought a super bodyguard with him, Polu.

Ever since I came to the capital, I have been in the yamen all day long, and I don't usually have holidays or rest, and I really haven't had a leisurely time to go shopping.It is a rare good opportunity that I don't have to go to work today and my wife is not around.

"Drive, drive!"

After walking two steps on the street, I heard the sound of carriages and horses behind me.Zhu Changyuan looked back and saw a carriage speeding down the street.

The speed was too fast, Zhu Changyuan quickly dodged aside.

At this time, there were a lot of tourists on the street, and many people were spoiled by the horses, and they cursed at each other.One of the young masters in brocade clothes said: "It's really strange, why are there so many horses and chariots today, four horses passed in a while."

"Hey, you don't know about your feelings, young man." A clerk from a cloth shop next to the street just came out of the door and said, "These are horses and carriages going out of the city, and they want to hire people from other places."

"Going to invite someone from another place, what happened?" Mr. Jin Yi asked standing beside him without rushing on his way.

"I don't know, it's okay to tell you." The clerk said: "It is said that Master Zhu of the Ministry of Industry will teach the art of cutting circles in the yamen in the future. Many people who have heard the news in the capital have hurriedly informed their teachers and friends. Come and watch."

"Oh..." A middle-aged man in his 30s came up behind Mr. Jinyi at some point, and said with a drawn out tone, "I know what you said, although I don't know what the art of cutting circles is. But I heard that it has been lost for more than a thousand years, if this Lord Zhu can really cut it out, it will be famous in history."

Young Master Jinyi was stunned when he heard the words, and said: "Master of Numerology, Circle Cutting Technique, where did you hear this information? Is this information true?"

The middle-aged man in his 30s said: "Of course it is true. Do you know who this Mr. Zhu who wants to cut the circle is?"

Zhu Changyuan was not far away, and when he heard that some folks knew that he was going to cut circles, he couldn't help being a little curious, and at the same time a little bit flustered, he simply stopped shopping and stopped to listen to a few people talking.

"Oh!" Young Master Jinyi was taken aback, and said, "Could it be Zhu Changyuan, the director of the Ministry of Industry who claims to be alive in Lu Ban?"

"Exactly." After the middle-aged man finished speaking, he laughed.

The clerk at the cloth shop didn’t take it seriously, and said, “I heard from my master that this art of circumcision has been lost for thousands of years, and Mr. Xu couldn’t restore it a few years ago. A guy who only knows bragging."

The middle-aged man shook his head with a smile, and said: "Although the reasoning is so, to be honest with you, I also think that Mr. Zhu is bluffing in all likelihood, but nothing is absolute. What if he really has this talent, you know This Lord Zhu is the mighty general who defended the Daling River, raided Riyue Island, killed Geng Zhongming skillfully, and went straight to Shenyang Wei."

"That's impossible?" Young Master Jinyi slapped his thigh, shook his head, and said, "You don't understand the art of cutting circles, so you can just talk nonsense, but I have studied the ancients' method of cutting circles many times. , It’s really, really completely incomprehensible.”

"Yes." An old man next to him also joined the discussion circle, glanced at the clerk of the cloth shop with a little curiosity, and said, "Little man, I'm surprised, why do you, a clerk in the cloth shop, know Cutting circle art?"

This is purely a question, not the slightest contempt.

The clerk in the cloth shop said: "I heard what my master said." Just now when I said this, I heard a rather serious reprimand from inside the shop: "Liu Ergou, what are you talking about outside? Come back to work, don't you want to do it?"

"Here we come, here we come." The store clerk made a face for everyone and said, "Everyone, I'll take my leave first." After speaking, he returned to the store.

"Old man Huang Mingyu." The old man first introduced himself.

"Hello, Mr. Huang!" Everyone saluted the old man.

"To be honest, I have an old friend named Song Yingxing, who is from Fengxin in Jiangxi Province. He can be regarded as a generation of masters of algebra. He has been thinking about the art of cutting circles for several months, but he has not found anything. Fortunately, he recently visited relatives in Tianjin Wei. , Hearing that Master Zhu gave a lecture on the art of circumcision, the old man has already sent someone to Xingye to invite him to come."

Song Yingxing?
Others may not be familiar with this person, but Zhu Changyuan is very familiar with it. I used to come across this guy every time I studied history in elementary school, middle school, and high school. This guy is so famous because he wrote a very famous book The very famous book is called "Heavenly Creation".

"Mr. Song is a master of algebra. He has been thinking hard for several months and found nothing. Although Mr. Zhu is invincible, he is also a person who is admired by me. But if he can reshape Zu Chongzhi's great art of cutting the circle thousands of years ago, I will say that I really can’t believe it, and I can’t believe it.”

Young Master Jinyi accepted Huang Mingyu's words, and after finishing speaking, he bowed to Huang Mingyu, and said: "I am not talented, I also have a little research on numerology."

"Oh?" Huang Mingyu's eyes lit up, and she said, "So he's a fellow?"

Young Master Jinyi said: "Don't dare, the junior Cheng Buchou is a mere late learner, and dare not sit on an equal footing with the seniors."

Huang Mingyu stared at Cheng Buchou for a few seconds, and said: "A master of contemporary mathematics, Mr. Cheng, the author of "Algorithms of Tongzong", don't you know Mr. Cheng?"

With a proud smile on Cheng Buchou's face, he said, "It's just mere great-grandfather!"

"Disrespect, disrespect!" Huang Mingyu cupped his hands and bowed his head deeply, and said, "Master Cheng is the ancestor of abacus prescribing. During the Wanli period, he participated in the whipping method of Zhang Juzheng, the chief assistant of the cabinet, and the national land settlement. It is really admirable."

The smile on Cheng Buchou's face was even better.

Even Zhu Changyuan who was standing next to him couldn't help being moved.

Finding the square and the cube were the biggest problems in ancient Chinese mathematics. This man named Cheng Dawei actually invented the method of calculating the square root with an abacus. It is no exaggeration to say that he is the originator of a generation.

According to historical records, it took Zu Chongzhi several years to calculate pi.It is not because the calculation method of pi is complicated, but the square root is too cumbersome, and it is difficult to open to eight digits after the decimal point.

Zhu Changyuan sometimes thought that Zu Chongzhi had wasted several years to calculate pi, most of the time should be in the prescribing, and he often made mistakes. Once there was a mistake, he had to recalculate from the beginning, which was extremely troublesome.

"Mr. Huang, I'm overwhelmed." Cheng Buchou said the award, but the expression on his face was full of pride, which is not difficult to understand. Any family with such a coquettish ancestor will have this expression.

Cheng Buchou looked at Huang Mingyu, and continued: "My father always said that the great-grandfather had two unique skills in the world, and this abacus prescribing is only one of them."
