Chapter 63
"Next, Jin will teach you the ultimate mystery of spells." Liu Jin looked around and said.
Diao Chan retreated knowingly.
Xun Yu and the others looked happy, and finally got to the point.
"Jin was once taught a unique subject by a stranger, which he named 'mathematics'. The content of mathematics is extensive and profound, and Jin studied hard for several years, but he only learned a little bit."
Liu Jin had a look of emotion, thinking of the miserable days when he kept writing questions.
Xun Yu, Guo Jia, and the others were shocked. You, Liu Ziqian, are all masters in spells, and you actually said that you only learned a little bit. Doesn't this so-called "mathematics" have to be studied for a lifetime?
"Ziqian, since it's a senior's unique knowledge, isn't it a bit inappropriate to pass it on to us?" Xun Yu was a little embarrassed.
"It's okay, that senior said, find an opportunity to pass it on, and let mathematics flourish." Liu Jinman said indifferently.
Mathematics is the foundation of natural science, known as the "Queen of Science".
The height of mathematics also determines the height of human civilization.
But this process is obviously not smooth sailing. Countless geniuses have to work hard and accumulate little by little to open up new chapters one after another and promote the development of civilization.
Therefore, Liu Jin did not have the idea of cherishing himself with a broom and teaching his apprentices to starve his master to death.
Liu Jin took out a blank piece of paper, picked up a pen and wrote zero to nine on it, and 0 to 9 correspondingly below, as well as addition, subtraction, multiplication and division and their corresponding symbols.
"This is the most basic number and symbol in mathematics. It is very convenient and quick to write. Please take a look." Liu Jin handed the white paper to Xun Yu and the others.
Xun Yu took it, and didn't have time to look at the white paper, so he couldn't wait to read the content on it.
Confused at first glance, is this crooked symbol the basis of so-called mathematics?
But soon Xun Yu discovered the convenience of these symbols, which can be written in one or two strokes, which is much simpler than the Han Li with many strokes.
So Xun Yu picked up a pen and began to write and draw.
Guo Jia, Xi Zhong and others didn't bother, they all looked at these symbols curiously.
Xun Yu went through the experiment and found that using these new symbols to calculate, the time saved was more than [-]%, and he was shocked.
Let’s not talk about the follow-up content of this mathematics, only these new numbers and symbols, if used for accounting, will save a lot of manpower, material resources and time.
But Xun Yu quickly discovered the problem, and asked, "Ziqian, how to write ten, hundred, thousand, ten thousand or even bigger with these ten numbers?"
"Then you have to adopt the bit value method, the high bit is on the left, the low bit is on the right, and write from left to right."
Liu Jin patiently explained to them, and at the same time wrote down some commonly used mathematical symbols such as two-digit, three-digit, four-digit numbers, decimal point, percent sign, fraction line, etc. on the paper, and marked the representative significance.
"Let's teach these today. You should familiarize yourself with the basics first."
Liu Jin looked up at the sky, and it was almost dark, and then said: "Let's eat at Jin's house tonight, let's have a drink together."
"Okay, okay, then Jia is welcome." Guo Jia said with a smile.
"Then thank you Ziqian." Xun Yu and the others thanked them without being pretentious, mainly focusing on how bad the food they ate today was.
Liu Jin waved his hand and went to prepare things.
The six people in the room quickly picked up their pens to take notes, copied the things on the white paper, and studied them slowly when they went back.
Not long after, Zhao Dafu came to invite everyone to have dinner next door.
What Liu Jin prepares is a barbecue. There is charcoal in the copper basin, and the big meat skewers are constantly turning on the copper basin.
The fat on the meat skewers fell on the charcoal, sparking a flame from time to time.
This is what Xun Yu and the others saw when they came in. The smell of the room filled the nostrils, and they couldn't help swallowing their saliva.
"Ziqian is really versatile. Anything can be turned into magic in your hands." Guo Jia squatted in front of Liu Jin, staring at the barbecue, his Adam's apple kept moving.
Liu Jin looked at Guo Jia speechlessly, can you wipe off the drool before you speak.
I flipped the meat skewers twice, sprinkled with cumin chili powder, and the fragrance was more intense.
Putting the meat skewers on the plate, Liu Jin signaled to several people that they could eat, and then handed the wine gourd to Guo Jia, letting them do whatever they wanted.
Then Liu Jin took a few skewers and put them on the copper basin to roast.
A few people ate meat and wine, and their mouths were full of oil, so happy.
……
At the same time, Lu Bu, Gao Shun, and Zhang Liao finally arrived in Luoyang following the Xiaohuangmen who announced the decree.
It took more than a month to travel more than 2000 miles from Wuyuan to Luoyang.
Lu Bu, Gao Shun, and Zhang Liao had a clear understanding of these little yellow gates.
When you encounter a city, you must enter, and when it snows, you must stop.
Everywhere they go, these little yellow gates will definitely take out the guard of honor to proclaim the decree, euphemistically saying: "The majesty of the gods should not be underestimated, and the majesty of the royal family must not be lost."
Therefore, the officials in each place must entertain their group with delicious food and drink.
What's more, money and jewels were sent one after another.
These little yellow gates never refuse anyone who comes, if they can't take it anymore, they probably can wait until the Chinese New Year is over before coming back.
Lu Bu and the others also took some symbolically, not because they didn't want it, but because they were afraid that Xiao Huangmen would go back and sue, and on the other hand, there was no place to put it.
Of course there were also beauties who sent them, but Gao Shun and Zhang Liao didn't accept them. No matter how itchy Lu Bu was, he was too embarrassed to eat alone.
When the road was blocked by heavy snow, those little yellow gates would not leave immediately, and they had to wait until the road conditions improved before leaving.
After this journey, the three of Lu Bu felt fatter.
When they arrived in Luoyang, Xiao Huang's gatekeeper Lu Bu Gaoshun and Zhang Liao arranged to rest in the post house, and hurried into the palace to return to his command.
……
Xun Yu and the others left after eating and drinking. Liu Jin gave each of them two gourds of wine and a hundred sheets of white paper.
Walking on the road, Xu Fu asked, "What is the intention of Ziqian's actions today?"
"Exercise both kindness and prestige." Xun Yu said slowly.
"That's right. On the one hand, he showed his strength, and on the other hand, he gave us some gifts." Xun You nodded in agreement.
"But what is he planning?" Chen Qun was very puzzled.
Xi Zhong glanced at Guo Jia, and said with a smile: "What else can we figure out, he knows that we have guessed his identity, and he doesn't want us to say it."
"No, then there's no need to perform martial arts and give gifts at the same time, just say no." Chen Qun asked.
"It's okay for one or two people to know. There are six of us. Why don't you tell your relatives and elders when you get home?" Guo Jia asked rhetorically.
"That's right, when the time comes, one person will spread it to ten people, and ten people will spread it to one hundred people. Ziqian thinks these entertainments are troublesome." Xun Yu said.
"Now that I have collected his things, we should keep silent when we go back, or think about the consequences of offending him." Xun You said quietly.
Thinking of the force that Liu Jin and Dian Wei displayed during the battle, several people fell silent.
If the news about him spread, it would be impossible to kill them, but it seems that no one can stop them if they beat them up.
That's all, cannibalism is short-mouthed and soft-hearted, so don't take the initiative to mention it after you go home.
