Lao Cheng was stunned. He probably never dreamed that there would be people studying this in the world. He opened his mouth wide and could not speak.
Seeing that Old Cheng was dumbfounded, Yun Ye quickly shook his arm. Only then did Old Cheng come back to his senses and couldn't help but ask: "What else did you teach?"
"Arithmetic, physics, geometry, mechanical drawing, map drawing, metal casting, and some other elementary subjects." Yun Ye explained all the knowledge he learned in school in one breath.
"What kind of science does salt making belong to?'
"Physics, simple dissolution, filtration, detoxification, evaporation, and crystallization are enough to make salt. In short, physics is a science that studies the laws of everything in the world. I will show my uncle one by one in the future."
"Can I see it? Doesn't your sect have no restrictions in this regard?"
"Learning, learning, you have to learn and ask at the same time. What can one person do? When my teacher taught me, he told me that once I have the opportunity, I must spread my knowledge throughout the world. The end of the chaos in the world is the beginning of civil rule.
, After years of chaos and chaos, I don’t know how much of our Han culture has been lost. This is all the hard work of our predecessors and the wealth of future generations. How can it not be heartbreaking? How dare you hide your secrets."
"I am a rough man, and anyone who looks down upon me is a bitch, but I don't dare to show any disrespect to you who are all educated people. There are several people in Chang'an City who will take you to your house for advice when you get back. They will see it in Lao Cheng's face.
I will definitely teach you. I, Old Cheng, am waiting to see the day when you become a master of knowledge. Since you have learned arithmetic, you have already won the praise of several people in the army. Let’s see how far you have learned it, okay?”
Seeing that Lao Cheng wanted to test himself, Yun Ye secretly laughed in his heart. In the Tang Dynasty where "Three folding well, chicken and rabbit in the same cage, and Han Xin ordering troops were all extremely difficult problems, Yun Ye didn't believe there were any problems that could test him."
"Uncle, you might as well call a few more people and prepare a few more difficult questions. It doesn't matter if you put in more effort. My nephew hasn't eaten yet."
Seeing Yun Ye's arrogance, Cheng Yaojin was rarely angry, and he took out a jade pendant from his arms, green jade? Yun Ye recognized it at a glance as a very rich green jade. If you don't have tens of millions in the future, you won't want it.
Asked the price. Holding back the drool that was about to drip, he asked: "Uncle, do you want to give it to your nephew?" He reached out to take it, but Lao Cheng returned it and stuffed it into his arms. "Want it? If you win three thumbs up, you can get it."
Yours." After saying that, he opened the curtain and went out.
Yun Ye finally didn't have to kneel anymore. The kneeling just now was killing him. His thighs were so sore and his buttocks were so swollen that they felt like they were two big. He carefully spread his legs, sat down, and stuffed a piece of sauced pork into his mouth.
, chewed it deliciously, and it turned out to be beef. In the Tang Dynasty, there was a penalty for killing cows. How come this old guy can kill cows as he likes? Looking back, there is probably no one who has no eyesight who would run to the left.
In the Wuwei Camp, a cattle criminal was caught and killed. A few mouthfuls of beef, two pieces of cooked mutton, a small half of a deer leg, and a belly. Yun Ye suddenly felt that life was so beautiful. He held the teapot and drank half a pot of tea, the raw tea of the Tang Dynasty.
, was ground into powder, and the grassy smell went straight to the brain, so he drank it with force, just as a vitamin supplement. Old Cheng had not come back yet, and Cheng Chumo was nowhere to be seen. Bored, Yun Ye fell asleep on the carpet with his arms as pillow.
go.
Yun Ye lay sprawled on the carpet, snoring intermittently, interspersed with sobs. He didn't know what he was dreaming about, and his face was full of tears. Cheng Chumo walked in gently, and seeing Yun Ye like this, he shook his head and said
He gently opened the curtain and went out. Standing outside the tent was a middle-aged scribe with his arms folded and a look of pride on his face. He was originally dissatisfied with Cheng Yaojin asking him to compete with Yun Ye and wanted to study arithmetic on his own.
It has been nearly twenty years, but now I have to compete with a young man who is still young. If it had not been ordered by the general, I would have thrown away my sleeves. I didn't want to condescend to teach this kid, but he fell asleep soundly. He is really not a son of a man.
Cheng Chumo looked at the livid face of the middle-aged scribe and felt unhappy. My brother worked day and night to make salt for the entire army. Today he traveled more than sixty miles. How could it be rude for a fourteen-year-old or fifteen-year-old to fall asleep?
Yes, this period of time has been very hard for my brother. I haven't seen him shed tears even when he fell asleep. Apart from being able to write and calculate, what else do you have? Thinking about it, your face is even more ugly.
"Captain, you are really rude. You pretended to be asleep to avoid taking the exam. I originally had the intention of giving guidance. It seems that you can't carve out rotten wood. I'm going to resign!" The middle-aged scribe didn't care about Cheng Chumo's gloomy face.
He arched his hands and wanted to retreat.
Cheng Chumo reached out and grabbed the scribe's sleeve: "Mr. Huang, please be patient. Since the general has given the order, it would be better for you to stay."
"This boy is rude, and his talent and virtue must be limited. He is a country boy, but he is not qualified to talk about arithmetic. I, Huang Zhien, have gone through many ups and downs since I started school. I became a disciple of Mr. Liu in the Imperial College and studied for seven years before I got a glimpse of the arithmetic.
, Studying is not easy. For the sake of the general, Huang Zhien reluctantly did it, but he was so humiliated. Huang said goodbye! "Cheng Chumo told himself with the general. Huang Zhien could no longer suppress his anger, so he threw up his sleeves and left. Then he turned around.
Just heard a lazy voice.
"It's not easy after seven years of study. Can you solve the nine-square grid? Can you know the rope log? Do you know the Pythagorean algorithm? How high is Mount Tai? How much sand does the Yellow River carry?"
Huang Zhien looked at Yun Ye who was leaning against the tent door in disbelief and said with a trembling voice: "Two and four are shoulders, six and eight are feet, seven on the left and three on the right. Wearing nine shoes and one is the correct solution to the nine palaces. I don't know how deep the well is, and I don't know how long the rope is.
How much? Four feet are left after folding three times into the well, one foot after folding four times into the well, the depth of the well is eight feet, and the length of the rope is thirty-six feet. The Pythagorean chapter of "Nine Chapters of Arithmetic" says: Hook three strands, four and five, I know it but don't know it.
So, how high is Mount Tai? How much sand does the Yellow River carry? God knows."
"Everything in the world is immeasurable. You can measure the height of a mountain with the shadow of a mountain, or measure the Yellow River with a bucket of water. Don't you know? According to Yun Ye's knowledge, the method of proving Pythagorean is no less than five hundred. What you have learned should be put to practical use. Otherwise, why should you imitate him?"
"How did you know? How did you know? The secrets of the Imperial Academy are not revealed to anyone. I just heard my mentor mention it, but you actually know it very well. How is it?"
"There are so many masters of arithmetic in the world. Why do you only know about the Imperial College? Nine palaces can be solved. Can the sixteenth house be solved? Can the thirty-two houses be solved? Do you know one yuan, two yuan, three yuan, and multiple yuan? A few interesting questions, etc.
How ridiculous it is to regard it as a treasure and keep it secret. Such questions are just a childhood game. It is really ridiculous for a frog at the bottom of a well to guess the size of the sky."
Huang Zhien felt a roar in his ears. Some of what Yun Ye said were just legends, and some were unheard of. He was an expert and knew that Yun Ye was not just talking nonsense. Don't talk about yourself, I'm afraid that his mentor would not be much better than himself.
Yun Ye walked over to Huang Zhien, picked up a branch, and drew a Pythagorean circle and a Pythagorean square on the ground. Then he threw away the branch, dusted his hands and said casually: "I'm rude today.
The sage Zhao Shuang’s Pythagorean square chart and my master’s Pythagorean square chart are all advantageous to you, so take it as an apology.”
Huang Zhien's mind was no longer on Yun Ye's rudeness. He was lying on the ground mumbling words and writing and drawing with his fingers. He was not paying attention to what Yun Ye and Cheng Chumo were doing.
Cheng Chumo slapped Yun Ye hard: "As expected of my brother, I knew you wouldn't lose to Suan Ding. As expected, drinking is not allowed in the army, otherwise you and I will get drunk."
Yun Ye rubbed his shoulders with a look of resentment on his face. The father and son spanked each other and slapped each other on the shoulders. They didn't care whether others could bear it or not. He quickly stopped slapping his hands again, but they fell apart after they were slapped.
"Brother, I've been on the road all morning and my whole body stinks with sweat. It's very rude to see Uncle Cheng again. It's more polite to let me take a shower and change clothes." Yun Ye only now felt a stinging pain in his buttocks. Old Cheng's slap wasn't it.
Anyone can bear it? Yun Ye was rubbing his buttocks, and Cheng Chumo had a look of sympathy on his face. It seemed that he had received this slap as well. "Let's go together. Now I feel uncomfortable all over without taking a shower for a day. It's strange. I used to be in the capital.
My mother used a feather duster to force me to take a shower. Now no one is forcing me to do so, but I feel uncomfortable if I don’t take a shower. What’s the point? Am I just a cheap donkey who won’t go away even if I’m beaten, and will go backwards even if I’m beaten?”
"This is a matter of habit. A person can develop a habit in fifteen days. If you don't believe it, you find a pig and knock on the pig trough every day before feeding. After ten days, even if you don't feed, you just knock on the pig trough.
, the pigs will also come running over."
"This is really amazing. If I knock on your rice bowl, will you hear the sound and run towards me more than ten days later?"
The two brothers went to the back tent to take a shower, arm in arm. General Cheng sat in the main tent and waited with no one on the left and no one on the right. He murmured in his heart, is that boy really talented? He didn't go to the exam in person, so he saved it.
To save some face for Yun Ye, I didn’t expect this kid to be able to fight against Huang Zhien for so long. It’s amazing. Huang Zhien is also considered the leader in arithmetic in the capital. In order to solve the logistics problem of the army, he went to Liu Xin several times to solve the problem. Then
The old immortal still looked at himself, but he really couldn't bear the kindness, so he sent Huang Zhien to help him. Huang Zhien lived up to his talent and reputation. The logistics in the army were much smoother. It is not easy for Yun Boy to compete with him until now.
Ah, I made a mistake. A fourteen-year-old kid can compete with a forty-year-old middle-aged man without falling behind. What a monster he will be when he grows up.
Thinking of this, Lao Cheng couldn't sit still anymore, got up and walked to the sleeping tent. From a distance, he saw a group of people surrounding the entrance of the tent, but there was no sound. When the sergeants saw the arrival of the general, they dispersed. Huang Zhien was seen lying on the ground.
, muttering words in his mouth, writing and drawing with his hands, his body covered with dust, as if he was in a state of madness. But Yun Ye was nowhere to be seen. Lao Cheng was very curious. He raised his hand and called the guard guarding the sleeping tent, asking what was going on, where was Yun Ye?
Went. The guard also went to the salt mine with Cheng Chumo. He had seen the magic of mining salt. He had heard the story of the Monkey King and had admired Yun Ye for a long time. He had been waiting for the general to ask him, with a look of disdain on his face.
In just a few words, Yun Ye told the story from front to back about how Huang Zhien went crazy.
Lao Cheng glanced at Huang Zhien, who was still calculating on the ground, and ordered his guards to provide him with an umbrella to protect him from the sun. He also prepared a pot of tea for later use, and then turned back to the commander's tent. As soon as he entered the commander's tent, he burst into laughter.
Then the big account was spread.
