Take a plane to the Ming Dynasty

Chapter 160 Honor Your Parents
After Zhu Changyuan entered the room, a familiar smell came over his face, almost choking him out of breath.

"Dad, why are you smoking again? Didn't you quit?"

Dad was lying in the hall of the house smoking a cigarette while watching TV. Hearing Zhu Changyuan's voice, he raised his head and looked towards the door, and said, "Little brat, do you dare to teach Dad a lesson?"

Zhu Changyuan waved his hands and said, "How is that possible? I only care about your body."

I changed my shoes and went into the house, and sat next to my dad.

Mom took out a few fresh oranges from the refrigerator and put them on the table, and said, "You won't listen to me, but you won't listen to your precious son?"

Dad strangled the cigarette in his hand, sat up, picked up the orange and ate it, and said while eating, "I quit it at first, didn't I feel a little emotional after hearing about Lao Gao today, man, I don't know when I said no It’s gone, don’t you want to enjoy more while you’re alive?”

Zhu Changyuan listened to what he said, and said: "Which old Gao?"

"Previously the general manager of our unit."

After the father finished speaking, he said to his mother: "Go and open the window to let the air in, so as not to smoke your son!"

Zhu Changyuan was instantly blissful.

Mom said unwillingly: "It deserves it."

Just now my mother was fighting with my father. My mother refused to let my father smoke. My father was disobedient. My mother closed all the windows in the house in a rage. The euphemistic name is: suffocate you, let you enjoy it smoke.

Zhu Changyuan heard the unreasonable quarrel between the two of them, smiled and said: "Mom, you are going to be smoked together." Suddenly remembering what Dad said about Gao Dezhong just now, he said: "Dad, what did you say about Gao Dezhong? ,do you died?"

Listening to his father's tone just now, even if Gao Dezhong does not die, he is not far from death.

"No, why should I go to see him when he's dead?" Dad subconsciously took out the cigarette again, looked at Zhu Changyuan, and stuffed it back.

The mother opened all the windows in the room, returned to the side of the father and son, and complained: "This damn Gao Dezhong, if you ask me, you shouldn't go to see him, what did he do to you at that time, have you forgotten? "

"Go and go." Dad said, "I have long hair but short knowledge."

Dad scolds mom, every time this sentence.

In fact, my father didn't want to go either, but after all, he had a relationship with his colleagues for decades, even if it wasn't for Gao Dezhong's face, but for the face of his colleagues in the whole unit, he still wanted to see it.

"What disease?" Zhu Changyuan always had a premonition that Gao Dezhong's disease might have something to do with him. It couldn't be that he got mercury from two thermometers last time and killed him.

If that's the case, the old man killed a living being.

Forget it, it's not a big deal, although it's the first time to kill someone in this world, but in the parallel world, I don't know how many people have been killed, and there is no shortage of Gao Dezhong.

"I don't know either." Dad sighed deeply, and said after a long time, "Maybe it's because of being in a high position and being indiscriminate on weekdays, which caused some disasters."

Although I don't know what happened to Lao Gao, but we are all colleagues in the same unit, and I have heard some rumors. Some people say that Lao Gao has syphilis, some say it is a strange disease, and some even say that he has AIDS.

That's not counting, even the beautiful woman in the office of the unit's general affairs department was unlucky with her.

I'm stupid, it's really Lao Tzu's trouble.

At that time, Zhu Changyuan just wanted to play a prank to teach Lao Gao a lesson, but he didn't expect that Mercury was so lethal that it forced Lao Gao to this point. According to his father, he probably won't live long.

"Have you eaten yet?" Mom asked concerned.

Zhu Changyuan really wanted to say that he had eaten it, and he would eat it with your two daughters-in-law, but he stopped and said with a smile: "I have eaten it, mom, you chat, I will go online."

He ran to his bedroom, turned on the computer, and started tinkering.

I found an old notebook in my room, wrote and drew, turned on the computer and looked up the information for a long time, and after clarifying the idea of ​​the whole circumcision technique, I started to calculate.

Circle cutting technique is to continuously double the inscribed regular polygon of the circle. When the number of sides increases to a certain extent, the perimeter of the polygon is very close to the perimeter of the circle.

It sounds troublesome, but it is actually very simple to calculate, which is to find the side length of the polygon.

First find the side length of the hexagon, then find the side length of the dodecagon according to the side length of the hexagon, and then find the side length of the 24-gon according to the side length of the dodecagon.

In this way, go down in turn, respectively.

48-gon, regular 96-gon, regular 190-gon, until 280-octagon, can get Zu Chongzhi's accurate pi.

Yes, you read that right, all the side lengths are obtained and calculated, not measured like Li Ji's funny.

Starting from the side lengths of the regular hexagon, and counting to twelve thousand two eighty-one octagons, a total of eleven strides are required.

Each big step is divided into four small steps. The calculation method of each big step in the eleven big steps is exactly the same, and the knowledge used is only the Pythagorean theorem. The only difficulty is that each step of the eleven big steps requires the square root .And it is the square root of a decimal with more than seven digits.

The square root is very simple for modern people, and the calculator calculates the ball with one click.But in ancient times, the square root of these eight decimals could really kill people.

As far as all the square roots in the circle cutting technique are concerned, the ancients may not be able to calculate them in ten days, but modern people have calculators, and they can do it in two to ten minutes at most.

(I’ll say it again, the principle of cutting circles is really simple, junior high school knowledge is enough, students who don’t understand should study it by themselves, don’t say when the protagonist became a mathematician...it’s boring.)
The first step is to divide the hexagons into dodecagons, and calculate the side lengths of the dodecagons from the side lengths of the hexagons.

The second step is to cut out the regular 24-gon, and calculate the side length of the 24-gon from the side length of the dodecagon.

. . .

Step No.11, calculate the side length of 280 octagons.

The length of a side multiplied by the number of sides is the circumference, and then divided by the diameter, the ratio of circumference to diameter is obtained, which is pi.

Finally, after cutting No.11 weight, Zhu Changyuan's ideal pi was cut, which is 3.1415926 accurate to seven decimal places.

Call it a day.

Zhu Changyuan carefully copied every step of calculation and every data in his notebook clearly, with a smile on his mouth.

Put the notebook for writing notes in the system, and glanced at the wall clock above his head, it was exactly nine o'clock.

Call Liu Guang and say, "Dad, where are you?"

Liu Guang excitedly grabbed the phone and stuck it to his face, kissing Tian Linger's ass more than Tian Linger's buttocks, and said: "Brother Dachang, why are you calling me back? Did the goods come? Where are we? Go pretend!"

Pretend to be your uncle.

Zhu Changyuan cursed in his heart, and said cheerfully: "Dad, you drive downstairs to our house, come here quickly, I have something to talk to you about."

Erdanzi said: "You frankly give me a confirmation letter, is the product arrived? Do I want to drive a truck over there?"

"Stuck with your grandma, return the truck? Do you want to scare this baby to death at night? Come quickly, I have something to discuss with you."

Liu Erdanzi's house was not far from Zhu Changyuan's house, and there was no traffic jam on the road at nine o'clock in the evening, so he arrived downstairs in 10 minutes.

Zhu Changyuan bid farewell to his parents, went downstairs to Liu Erdanzi's red Audi Q5, and said, "Go out and have a look."

Liu Erdanzi was unhappy, and said with a straight face, "Where's my goods?"

Zhu Changyuan said: "What the hell do you know about the goods? If you don't have the goods, just sell your Tian Linger."

Liu Guang had a bitter face, and said in a crying voice: "Brother Dachang, you don't know, is it easy for me to open a store? I sold a batch of goods for eight days, eight days, and then the stock was out for several days. months. Every day someone comes to my door and asks me when the goods will arrive."

Zhu Changyuan ignored him and said, "Go, take me to the supermarket outside first."

After looking around outside, I finally found a supermarket that was not closed, and almost emptied the store of lighters, mirrors, signature pens, transparent glasses, eyebrow pencils, lipsticks, etc. for women.

Liu Erdanzi was almost dumbfounded, and said, "Why are you buying these things? You still buy so much."

Zhu Changyuan said: "Leave me alone, go and pay the bill."

After paying the bill, he found a western restaurant to sit down, and began to talk about some issues that Zhu Changyuan had been thinking about for a long time.

For example, today I suddenly felt that I have not been filial to my parents since I became rich.He asked Liu Guang, "Erd, did you spend a lot of money on buying fertilizer, seeds and cement for me a while ago?"

Liu Guang said with a weeping face, "It took 1000 million yuan to buy chemical fertilizers alone. Do you think it's too much?" Speaking of this, he began to settle accounts again, "Wheat seeds cost more than 160 million yuan, and cement costs..."

Zhu Changyuan didn't bother to pay attention to him, he waved his hand and said, "You sold all the expensive furniture that I gave you last time, so don't count the small money for me, tell me, how much is left?"

Liu Erdanzi grimaced and said, "There are more than 500 million left."

Zhu Changyuan didn't believe it, and said: "You boy, don't give me a sloppy eye. When I look back, I will check your account and tell me the truth, how much is left, I will not miss your share, otherwise if the boss from abroad knows that we are pocketed, he will go down to the bank." Will not cooperate with us again."

Liu Guangxin thought it was true, widened his eyes and said, "That's it."

"Yes, do you know why the goods have not come in for so long this time? That's because the boss has already begun to suspect, saying that we are pocketing our own money." As he spoke, he said loudly, "How much money do you have? You can't lie to me. .”

Erdanzi Liu chuckled, and said, "Excluding those who bought things, the remaining working capital in the store is more than 800 million. I just underreported 300 million. That's my part of the money!"

Zhu Changyuan slapped the table, pretending to be angry, and said: "You fucking almost caused me trouble. You can embezzle only how much money you have, and the benefits will be great in the future. If you don't want me to find someone else to cooperate. I'm back and forth I bought you three Audis, can you see that I wasted my money indiscriminately?"

"No!" Liu Guang replied.

"It's fine if you don't have one." Zhu Changyuan continued to pretend to scare him, "The boss abroad has all eyes and hands, does the mafia know that he's just his little brother, if you dare to do something, kill you with one shot, don't blame me for not reminding you beforehand .”

Liu Guang couldn't help shivering.

"Okay, don't be too scared." Zhu Changyuan handed a cup of tea to Liu Guang, "As long as you do things well, you won't have too much trouble. Don't forget to invite an accountant to take care of the accounts. Find someone who manages supplies, you are too busy alone."

"Why don't you believe me?" Liu Guang quit.

"Believe me, I'll just believe you, okay?"

To scare him a little bit, Zhu Changyuan did enough, anyway, since he was young, it doesn't matter if he gets a little cheap first, as long as he doesn't have second thoughts about himself.

To be honest, Liu Guang is a bit greedy, but at least he is diligent and reliable in his work, and has never missed a job. No one is perfect, and it would be nice to be perfect.

And having said that, if you change someone now, in the face of a huge amount of money, there is no guarantee that there will be no problems. It is very likely that it is not a little bit of corruption. Maybe Zhu Changyuan will not be able to find anyone once he travels from another world.

"It's really only 800 million?" Zhu Changyuan asked in disbelief.

Liu Guang smiled bitterly, and said, "It's really only 800 million. All my consumption and receipts here have receipts and receipts. I'll get them to you in the car."

"Forget it, if you don't believe me, I will trust someone, mainly because I am afraid that the big boss will get mad." I gave Liu Erdanzi a little favor at the right time, took the savings card from his hand, and said, "800 million."

"I'm planning to buy a private villa in Nandu. I wonder if the money is enough?" Zhu Changyuan asked.

The purpose of buying a villa is to live for my parents. Both of them have worked hard for most of their lives. Now that the son has money, it is time for his parents to enjoy it and live the life of a rich man.

I also want to buy a luxury car for my dad and find a few private doctors for my mom so that they can spend the rest of their lives well.

Zhu Changyuan clenched his fist and swore to himself.

"Cut." Liu Guang shook his head when he heard that Zhu Changyuan wanted to buy a villa, and said, "Brother, it's not brother, uh, it's not Xiaoguang. I look down on you, and you, with more than 1000 million yuan, are not considered rich in Nandu." .”

"Of course, more than 1000 million yuan can buy a villa in Nandu, but it can't buy a very good private villa." Liu Guang lit a cigarette, took two puffs and said, "Do you know Wangjiang Water Park? The real estate developed is not considered a villa, but a luxury residence."

"I've never heard of it." Zhu Changyuan replied honestly.

"You can buy a duplex building in Wangjiang Water Park with more than 1000 million yuan. Of course, the area is very large, more than 300 square meters, and it is the kind of fine decoration that can be moved in with bags." Liu Guang blew a smoke ring , said: "I don't want a villa, I just want a duplex like that."

He said it extremely wronged, as if it was the greatest ideal in his life.

Zhu Changyuan patted him on the shoulder and said: "Brothers who will, follow me and work hard, don't think about those devious ways, I will guarantee you to build a duplex in Wangjiang Water Park within two years, if you can't fulfill this promise , I will pay you a set."

"Really, brother, are you my real brother?" Liu Guang stubbed out his cigarette with a look of excitement.

"Of course it's true, I can still lie to you." Zhu Changyuan pushed the more than 1000 million card in front of Liu Guang, "Buy me a duplex in Wangjiang Garden first, don't pay the full amount, just pay 500 yuan first." Ten thousand, and pay in installments within the remaining five years. The rest of the money is kept as a backup.”
