Zhuge Liang was lying on the ground with a branch, and the hour of a stick of incense passed, and the smile on his face disappeared, just kept calculating.

Ma Hong looked at the busy Zhuge Liang and said with a dark smile: Hmph, I already knew that you couldn't even list the equations, after all, you didn't study high school physics, so you don't know what the formula for acceleration is?

Zhuge Liang calculated on the ground for a while, suddenly threw away the branch, and then put his finger on his eyebrows and thought carefully, and said secretly in his heart: How can I list the formula, the speed is constantly changing, constantly changing, the speed of the beginning and the speed of the end. Oh! By the way, then their average velocity must be the middle velocity, I just need to find the average velocity, and then multiply it by the time change.

Zhuge Liang thought of this and picked up the branch and calculated, and after a while, he listed the binary equations, and then began to solve the equations. Ma Hong was shocked at this time, and hurriedly stood behind Zhuge Liang to watch his solution. It doesn't matter if Ma Hong doesn't look at Zhuge Liang's equations, he was shocked when he saw it, although the writing of the equations of the ancients was very different from that of modern people, but Ma Hong still understood it. Zhuge Liang actually used the matching method to find a binary one-time equation, is this Zhuge Liang a genius? Or was there already a solution to a binary equation in this era?

Ma Hong regretted that he had read less books at this time, and his palms began to sweat, and he couldn't help asking: "Senior Brother Zhuge , is your method of finding this equation self-created?" ”

Zhuge Liang raised his head, a trace of surprise flashed in his eyes, and then said: "More than three hundred years ago, there was a solution to a binary equation, don't you know?" ”

Ma Hong was completely stunned, he still underestimated the ancients, he still read less when he was in school, he even thought that the solution of the binary equation was also in the Tang Dynasty at the earliest. Ma Hong sighed, Zhuge Liang had already begun to seek roots. When Zhuge Liang was about to seek roots, he suddenly stopped, raised his head and said to Ma Hong: "Your topic shouldn't be so simple!" ”

Ma Hong was told by Zhuge Liang, so he looked carefully at Zhuge Liang's equation, and found a problem when he saw that it didn't matter, that is, Zhuge Liang's equation was written incorrectly. Although Zhuge Liang can solve binary equations, he does not know how to use the relationship between acceleration and distance. A smile appeared at the corner of Ma Hong's mouth, and then he sat back on his stool, facing the pond, and his heart was full of joy.

"The wisdom of the ancients is truly not to be underestimated, and I will have to be careful in the future. Fortunately, I am a science student, and I have more literary knowledge than some liberal arts students, and I have not yet lost all the science knowledge I learned in high school. ”

"You really can't fool people by memorizing some Tang poems and Song lyrics, Pang Tong and Yang Yi don't like me at all, and Zhuge Liang doesn't have to try."

"Zhuge Liang! If you can even derive a formula between acceleration and distance, I really admire you, it's derived using the graphical method, I hope you don't think about it. ”

"Well, you have many titles in history, military strategist, politician, writer, inventor. It's just a pity that you're not a mathematician. ”

"Well, I'm still too capable, I knew that I would just list the ternary quadratic equation for you to find."

Ma Hong watched Zhuge Liang lying on the ground and busy working, he kept talking to himself in his heart, Zhuge Liang saw Ma Hong's expression, and he already realized that he was wrong.

Half an hour later, Ma Hong pulled Zhuge Liang up from the ground, smiled and said, "Senior brother! Don't lie on the ground, it's dirty. Zhuge Liang sighed and said to Ma Hong: "I admit defeat." ”

Ma Hong smiled slightly, stretched out his hand, raised it, and patted Zhuge Liang, who was half a head taller than him, on the shoulder. Then he said, "Senior brother! Senior brother teaches you how to make equations. ”

Then Ma Hong took the branch from Zhuge Liang and wrote the correct equation on the ground, and also drew a derivation diagram between acceleration and distance for Zhuge Liang, and briefly explained it to Zhuge Liang. Zhuge Liang is an extremely smart person, and after simply listening to Ma Hong, he has mastered it all.

Ma Hong looked at Zhuge Liang, who was dejected, and said secretly in his heart: Xueba! This IQ must have been a top student in my time, and any university in the world could be picked at will, well, provided that there was money. If Zhuge Liang was in my time, he could at least be a scientist! Such a person is unlikely to mislead him even with a national-style quality education. ”

Zhuge Liang walked to the river and lifted up the bamboo basket placed at the bottom of the river, there were at least twenty or thirty small fish in the bamboo basket, including two and a half catty carp. Zhuge Liang stretched out his hand and washed his face with water, then looked back at Ma Hong, and said loudly: "Senior Brother Ma, come and pack up the fish." ”

Ma Hong sighed, suddenly felt that something was wrong, and then looked at Zhuge Liang, the water droplets were flowing on Zhuge Liang's clean face, and the sunset sprinkled on his face, and the water droplets were also extraordinarily bright. Ma Hong smiled, this time he smiled happily, showing his white teeth, he answered Zhuge Liang loudly, and then ran to Zhuge Liang's side to help Zhuge Liang lift the bamboo basket.

It's just that Ma Hong just lifted the bamboo basket when suddenly the soles of his feet slipped and fell into the pond. Zhuge Liang saw Ma Hong fall towards the pond, and hurriedly stretched out his hand to pull Ma Hong, but Zhuge Liang looked at his own strength, even if it was a small body like Ma Hong, he couldn't pull it, and he could only roll into the pond with two people. After the two men fell into the pond, they stood up and looked at each other and smiled, and then the two of them laughed.

After the two finished laughing, Zhuge Liang said: "Senior brother, to be honest, your "Peach Blossom Fu" is not very well written. ”

Ma Hong nodded and said, "Well, you're right, but well, your "Teacher Table" is well written. ”

Zhuge Liang was stunned for a moment and said, "Senior brother, what did you say?" ”

As soon as Ma Hong said his words, he realized that he had missed his mouth, and hurriedly smiled: "I mean you said it very well, my "Peach Blossom Fu" is really not good. ”

At this time, Yang Yi drove a group of sheep to the river to drink water, saw Ma Hong and Zhuge Liang standing in the water and laughing, and asked loudly: "Two senior brothers, what are you doing standing in the water?" ”

When Ma Hong saw Yang Yi coming back, he replied loudly: "Yang Xiaofei, you are so spineless, you actually call the later senior brother." ”

Yang Yi laughed and said: "Senior Brother Zhuge promised me to teach me the formation, and also help me watch the sheep, which is much better than you, a sheep thief, we have known each other for so many years, and you actually stole my sheep." ”

Ma Hong smiled: "Even if Senior Brother Zhuge helps you watch the sheep, we will steal it again." ”

Yang Yi snorted and said, "As long as you dare to steal my sheep again, I will spread the news of your painting of the Spring Palace to Xiangyang." ”

Ma Hong's face changed color instantly, and he looked at Zhuge Liang beside him, Zhuge Liang shrugged his shoulders and said innocently: "I didn't pass it on." ”

Ma Hong sighed and climbed ashore from the water, then took Yang Yi's hand and said, "Little fat! We are good brothers, I just made a joke, I promise not to steal your sheep in the future, how about it? ”

Yang Yi broke Ma Hong's hand and said, "Is this true? ”

Ma Hong nodded seriously and said, "When did I lie to you?" ”

Yang Yi nodded and said, "Now I don't think you dare to lie to me anymore, so be it!" If you help me herd the sheep, I can consider not poking them out. ”

Ma Hong hurriedly agreed, he knew that Yang Yi was a big mouth, and he always liked to talk everywhere, if he didn't care about Yang Yi's mouth, the next time he went to Xiangyang City, he would have another title, it would definitely not be an elegant title like Taohualang.

"By the way, I met Pang Tong on the mountain, and Pang Tong said that the teacher is looking for you and Senior Brother Zhuge and asked you to meet the teacher tonight."

After Yang Yi and Ma Hong finished speaking, the sheep drank enough water, Yang Yi drove the sheep back, Zhuge Liang and Ma Hong smiled at each other.

"Senior Brother Zhuge , I dreamed of a person last night, that person was a lupine scarf, majestic and heroic, and he was speaking generously in the hall."

Ma Hong took off the straw hat he was wearing on his head and buckled it on Zhuge Liang's head, then took off his clothes and wrung the water.

Zhuge Liang touched the straw hat, walked to the pond and Gu Ying said to himself: "Hehe, I think I am more romantic than you when I wear a straw hat." ”

"You don't want to ask me what I dreamed and what I heard the man say?" Ma Hong asked.

"What's the point of dreams?" Zhuge Liang said.

"I still remember what the man said, it's quite interesting."

"What words? Let's hear it. ”

Ma Hong saw that Zhuge Liang finally raised some interest, so he said: "I dreamed that the man was reciting words, as if there was a sentence called" Chenben cloth, ploughing in Nanyang, living in troubled times, not seeking to reach the princes. The first emperor did not take the ministers despicable, and he was humiliated, and between the three ministers, the ministers were grateful, and the first emperor was allowed to drive. ”

"Gone?" Zhuge Liang turned his back to Ma Hong and continued to hold the straw hat against the water.

"I remember intermittently, I didn't remember it all, do you remember a sentence that you listened to?" Ma Hong asked again.

"Tell me about it."

"The first emperor was cautious, so he sent his ministers to major events. Since receiving the order, he has been lamenting all night, fearing that the entrustment will not work, so as to hurt the wisdom of the first emperor, so he crossed Lu in May and went deep into the hair. Now the south has been decided, the armor is sufficient, as the commander of the three armies, the north is set in the Central Plains ......"

"Gone?"

"He said a lot, I only remember these few words."

Ma Hong said that in fact, he only memorized a few sentences when he became a teacher.

Zhuge Liang turned around and smiled at Ma Hong: "Listening to the words you read, it can be seen that the person in your dream is a powerful minister, with a position above ten thousand people under one person, no, to be precise, he may be in control of the emperor, he is doing what the emperor does not want to do." ”

The corners of Ma Hong's mouth curled up with a smile, and he secretly said in his heart: It seems that you know very well!
