Lao Cheng was already stunned, he probably never dreamed that there were still people in the world who studied this, and he couldn't speak with his mouth open.

Yun Ye saw that Lao Cheng was stupid, and hurriedly shook his arm. Lao Cheng came back to his senses at this time, and couldn't help asking: "What else did you teach?"

"Arithmetic, physics, geometry, mechanical drawing, cartography, metal casting, and so on." Yun Ye said everything he learned in school in one breath.

"What kind of science is salt making?"

"Physically, salt is produced by simple dissolution, filtration, detoxification, evaporation, and crystallization. In short, physics is a discipline that studies the laws of heaven and earth, and Rong Xiaonephew will show it to his uncle one by one in the future. ”

"Can the old man see it? Doesn't your school have this restriction? ”

"Learning, learning, you have to ask while learning, what can a person do? When the teacher taught me, he told me that once I had the opportunity, I must spread the questions of my middle school all over the world, and the end of the chaos in the world was the beginning of the rule of culture. The kid dares to hide his secrets. ”

"The old man is a rough man, and he looks down on those who are sour, but he is a learned person, the old man does not dare to have the slightest disrespect, there are a few in Chang'an City, and when the old man takes you to the door to ask for advice, they will teach you on the face of Lao Cheng, and I am waiting to see the day when you become a master of learning. Since you have studied arithmetic, this is called a few praises in the army, see how far you have learned, okay? ”

Yun Ye saw that Lao Cheng was going to test himself, and he smiled secretly in his heart, in this '" three-fold well, chickens and rabbits in the same cage, Han Xin's soldiers, all of which are super difficult Tang Dynasty, Yun Ye doesn't believe that there are any problems that can test himself.

"Uncle might as well call a few more, prepare a few more problems, it doesn't matter if you put in a little more effort, the little nephew hasn't eaten yet."

Seeing Yun Ye's arrogance, Cheng Biting Jin was rarely angry, and took out a jade pendant from his arms, green jade? Yun Ye recognized it at a glance as a green jade with a very full head, and if there are tens of millions in the future life, you don't have to ask the price. Holding back the drooling saliva that was about to fall, he asked, "Uncle wants to give it to the little nephew?" As he spoke, he was about to reach out and take it, but Lao Cheng put his hand back into his arms. Want? Win three likes, it's yours. Then he lifted the curtain and went out.

Yun Ye finally didn't have to kneel, the kneeling just now almost killed him, his thighs were extremely sore, and his buttocks seemed to be two big. Spread his legs carefully, sat down, stuffed a piece of sauce meat into his mouth, and chewed it beautifully, it turned out to be beef, wasn't it the Tang Dynasty that killed cattle was to be sentenced, how could this old guy kill cattle as he wanted? Looking back, there probably wouldn't be that short-sighted person who would run to Zuo Wuwei's camp to catch the cattle killer. A few bites 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, holding the teapot and pouring half a pot of tea, the raw tea of the Tang Dynasty was still ground to the end, and the smell of grass went straight to the brain, and he forcibly drank it, so he should supplement vitamins. Lao Cheng has not returned, and Cheng Chumo is nowhere to be seen. Boredom, Yun Ye fell asleep on the carpet with his arms on his pillow.

Yun Ye lay on the carpet on all fours, snoring intermittently, mixed with sobbing sounds from time to time, I don't know what to dream of, and his face was full of tears. Cheng Chumo walked in lightly, and when he saw Yun Ye like this, he shook his head and gently opened the curtain and went out. There was a middle-aged scribe standing outside the tent, with his hands caged and his face full of pride, he was originally dissatisfied with Cheng Biting Jin asking him to compete with Yun Ye, and wanted to study arithmetic by himself for nearly twenty years, but now he had to learn from a young student who had not dried up, if it wasn't for the general's order, he would have thrown his sleeves away. I don't want to deign to guide this kid, he actually fell asleep, he is really not a son of man. Cheng Chumo looked at the middle-aged scribe's iron-clad face, and didn't like it in his heart, my brother made salt for the whole army day and night, and he drove more than 60 miles today, what is rude about a fourteen or fifteen-year-old doll falling asleep, this time has been bitter for my brother, I didn't see tears when I fell asleep, what other skills do you have in addition to being able to write and calculate? Thinking about this, his face was even more ugly. …,

"Lord Captain, this shaft is really rude, pretending to sleep to avoid the school examination, there is still a heart of guidance in the next, it seems that the rotten wood cannot be carved, and he will retire in the next!" The middle-aged scribe didn't care about Cheng Chumo's gloomy face, and he wanted to retreat with a big thorn.

Cheng Chumo stretched out his hand and grabbed the scribe's sleeve: "Mr. Huang, don't be impatient, since the general has already given the order, it is better for you to stay." ”

"This son is rude, his talent must be limited, and he is also worthy of talking about arithmetic. Since I Huang Zhien tied my hair and went to school, I went through ups and downs before worshipping under Liu Laomen, who studied for seven years, only to take a peek at the door in arithmetic, it is not easy to study, for the sake of the general, Huang Zhien reluctantly did it, but suffered this great humiliation, Huang said goodbye"! Cheng Chumo told himself that Huang Zhien could no longer suppress his anger, so he threw up his sleeves and left. Before I turned around, I heard a lazy voice coming.

"After studying for seven years, it's not easy, can you solve it in the nine squares? What can rope logging know? 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 on the door of the tent in disbelief and said in a trembling voice: "Two or four is the shoulder, six or eight is the foot, seven on the left and three on the right, and one of the nine shoes is the correct solution of the nine palaces." The well does not know how deep it is, the rope does not know how long it is, three folds into the well more than four feet, four folds into the well more than one foot, the well is eight feet deep, and the rope is thirty-six feet long. "Nine Chapters of Arithmetic" Pythagorean Chapter Cloud: Hook three strands, four mysteries and five, I know it but I don't know why. How high is Mount Tai? How much sand does the Yellow River carry? God knows. ”

"There is no unmeasurable person in the world, measure the height of the mountain with the mountain yin, and measure the height of the Yellow River with the amount of water, Mr. Huang doesn't know? As far as Yun Ye knows, there are no less than five hundred methods of proving Pythagorean, and what you have learned should be put to use, otherwise, what will you do if you learn from him? ”

"How do you know? How do you know? The secret of the country is not revealed, but I have heard the teacher mention it, you know very well, what is the reason? ”

"There are so many masters of arithmetic in the world, why do you only know the national eunuch, the ninth palace can be solved, and the sixteenth palace can be solved? Can the 32 houses be solved? Do you know one, two, three, multiple? A few interesting questions, you actually regard them as treasures, secret, how ridiculous, such questions, just in the next childhood game, the frog at the bottom of the well vainly guesses the size of the sky, it is really ridiculous. ”

Huang Zhien only felt a boom in his ears, some of what Yun Ye said, some were just legends, and some were unheard of. He is an expert and knows that Yun Ye is not a mouthful. Don't talk about yourself, I'm afraid that my teacher is here, and he won't be much better than himself.

Yun Ye shook in front of Huang Zhien, picked up a branch, and casually drew a Pythagorean square diagram on the ground, a Pythagorean expansion diagram, and then threw away the branch, patted the dust on his hands and said casually: "Today, I am rude first, Zhao Shuang Xianzhe's Pythagorean square diagram, and the Pythagorean expansion diagram of the family teacher will be cheaper for you, and it will be regarded as an atonement." ”

Huang Zhien's mind was no longer on Yun Ye's rudeness, lying on the ground and chanting words in his mouth, writing and painting with his fingers, where did he still care about what Yun Ye and Cheng Chumo were doing.

Cheng Chumo slapped Yun Ye heavily: "If you are worthy of being my brother, I know that you will not lose to Sour Ding, sure enough, you are not allowed to drink alcohol in the army, otherwise you and my brother will rest when they get drunk." ”

Yun Ye rubbed his shoulders, his face was full of resentment, this father and son spanked one and patted the other's shoulders, and they didn't care if others couldn't stand it. Quickly stopped the palm that was slapped again, and it fell apart while shooting.

"Brother, the little brother has been on the road all morning, and his whole body smells of sweat, and Uncle Cheng is very rude when he sees him again, it is only right to let the little brother take a bath and change clothes." Yun Ye only now felt like a pinprick in his buttocks, and Lao Cheng's slap was not something anyone could bear. Yun Ye was rubbing his buttocks, and Cheng Chumo's face was full of sympathy, and it seemed that he had not suffered less from this slap. "Let's go together, I feel uncomfortable without taking a bath for a day now, it's strange, my mother used to force me to take a bath with a feather duster in the capital, but now no one forces me, I don't wash uncomfortable, what's the reason? Am I a cheap donkey, fighting and not leaving, pumping backwards? ”…,

"This is a matter of habit, a person can develop a habit in fifteen days, don't believe it, you find a pig, knock on the pig trough before feeding every day, ten days later, even if you don't feed, as long as you knock on the pig trough, the pig will run over."

"This is amazing, I knock on your rice bowl, will you hear the sound and run towards me in ten days?"

The brothers hooked their shoulders and went to the back tent to take a shower without mentioning it. General Cheng sat on the left side of the main tent and couldn't see anyone, and he couldn't see anyone on the right, muttering in his heart, could it be that kid really talented? I didn't go to the school in person, so I saved some face for Yun Ye, I didn't expect this kid to be able to fight against Huang Zhien for so long, amazing. Huang Zhien is also a leader in arithmetic in the capital, in order to solve the logistics problem of the army, he pulled down his old face and looked for Liu Xin several times, and the old immortal also gave himself a look of face, he really couldn't stand it, so he sent this Huang Zhien to help him, Huang Zhien did not live up to his reputation, the logistics in the army were much smoother, and now Yun Boy can compete with him until now, it is not easy. The old man has lost his eyes, and the fourteen-year-old doll can compete with a forty-year-old middle-aged person without falling behind, what a demon it will be when it grows up.

Thinking of this, Lao Cheng couldn't sit still anymore, got up and walked to the bedroom. From afar, I saw a crowd of people gathered at the door of the tent, but they were silent. When the sergeants saw the arrival of the general, they dispersed. I saw Huang Zhien lying on the ground, chanting words in his mouth, writing and painting under his hands, covered in dust as if he had fallen into madness. But Yun Ye was nowhere to be seen. Lao Cheng was curious. Raised his hand and summoned the guards guarding the sleeping tent and asked what was going on, where was Yun Ye. The guard also went to the salt mine with him, saw the magic of salt mining, heard the deeds of the Monkey King, and had already admired Yun Ye's five-body throw, and had already waited for the general to ask himself, and with a nonchagratory expression on his face, Yun Ye told Huang Zhien about Huang Zhien going crazy in a few words.

Lao Cheng glanced at Huang Zhien, who was still calculating on the ground, and instructed the guards to give him an umbrella to shade the sun, and prepare a pot of tea for later use, then turned around and returned to the tent. As soon as he entered the tent, a burst of laughter came out of the tent.
