Come on, Your Highness

Xie San finally knew what kind of evildoer he had invited to be a guest. He didn't come here to ask for advice, he was obviously here to debate.

And the sad thing is... Sometimes he is really speechless and can't continue arguing. Instead of chasing after the victory and arguing about winning or losing, this kid changed the subject calmly and passed a step for him to go down.

Is this a seven year old?Xie San was somewhat skeptical about life.

The two children Xie Siyuan and Xie Sigui couldn't hear it, they just felt that Xie San and He Xi were coming to each other, it was very intense, although they didn't understand some words, they were very excited just looking at them, and their blood surged up.

Especially for He Xichao, the admiration is almost overflowing, his eyes are bright.

In the end, Xie San said with shame: "How about you go with me to take the exam next year? If you don't know for sure, you will pass the exam."

"Brother Xie was joking, Xi Chao is still in the period of filial piety, but just wait, there will be such a day."

As He Xichao said, he looked at the time, "Brother Xie, it's getting late, I haven't seen the set of "Nine Chapters of Arithmetic", can I have the honor to take a look?"

Xie San was taken aback, "Are you really going to read this set of books?"

He Xichao said inexplicably: "Of course, didn't we agree?"

Xie San is not an idiot, in the bookstore he just treated He Xichao as a child who was smarter than ordinary people, and seeing him coming alone, not as tall as a bookshelf, he couldn't help feeling sorry for him.So he found books for him, gave him books, and even invited him to watch "Nine Chapters of Arithmetic" at the mansion. Xie San felt that the child was still young and would not have other thoughts.

But today, what He Xichao said and did completely subverted Xie San's perception of him.

Being able to restrain his playfulness, take notes carefully, arouse his goodwill, make test papers for him to comment and show his talents, and the unique viewpoints and rigorous logic displayed during the heated debate made Xie San feel compelled. Admiration, especially at the end, the eagerness to be strong and competitive that was pressed in time, ordinary people really can't do it.

Such a person is only seven years old, and Xie San couldn't help feeling vigilant when he was amazed.

After all, Xie's mansion is different from other places, the reputation is too high, there are several Jinshi alone, there are too many people who study and learn from teachers for fame and fortune, Xie San has to suspect that He Xichao had already had a certain idea at that time.

"Nine Chapters of Arithmetic" is probably not an excuse, an excuse to enter Xie's residence.

But even so, Xie San still didn't want to reject He Xichao, such a quick-witted and intelligent child, who wouldn't want to be in his family.

But He Xichao must be looked down upon by most people, so there is only... his grandfather.

Didn't expect He Xichao to watch it?Is it a posturing, or what?

Xie San changed his mind, and simply opened up and said: "Xi Chao, when grandfather is free, I will ask the old man to read these three articles. I will get back to you later."

He Xichao was surprised, "Brother Xie, is this going to recommend me to Elder Xie Ge?"

Xie San nodded, "I think your talent is enough, don't worry, I will speak for you."

However, He Xichao shook his head, "No need."

Xie San was shocked, "Why?"

He Xichao smiled and said, "Because I have no plans to find a master yet."

To be honest, Xie San never thought that He Xichao would refuse, no matter how humble a scholar encountered this opportunity, he would not pretend to decline.

Couldn't help but reminded him: "You have to think about it. Grandfather is a famous Confucianist all over the world. He is the only one in Daqi. There are countless people crying and asking for his advice. I am I sincerely recommend it to you.”

He Xichao nodded, "I don't doubt Brother Xie's words, and I admire him as an old man. But..." He stood up, raised his chin, and said rather arrogantly, "But I, He Xichao, am also unique in the world. Master doesn't care about name or official position, he has outstanding talent but also requires his character to be in harmony with me."

Xie San led the way with a dazed expression, and the arrogant and wanton words of the child behind him are still in his mind.

This is how confident and narcissistic he is in order to say it. Believe it or not, He Xichao will be drowned by the spittle of the students all over the world.

But at the same time, Xie Sanda felt a sense of admiration in his heart. He had only met He Xichao who was able to reject the well-known Mr. Xie Ge so straightforwardly.

I hope He Xichao will not regret it.

"Nine Chapters of Arithmetic is at my second brother's place. Sigui, is your father there?"

Xie Sigui said, "Yes, brother Xichao wants to read "Nine Chapters of Arithmetic"?"

"Ah."

Xie Si said, "It's my father's treasure. I can't even look at it at ordinary times. I'm afraid he won't lend it to you."

"Second uncle loves books like his life, and hates people who don't know how to flip through." Xie Siyuan mentioned again.

He Xichao asked: "Then what if you understand something?"

Xie San said: "If you understand the brief "Nine Chapters of Arithmetic" in the bookstore that day, my second brother will be happy."

"You can do this, Xi Chao?" Xie Sigui was completely stunned. He had touched the set of "Nine Chapters of Arithmetic", but his father found out, threw it out of the study, and stuffed him with a copy There are brief versions everywhere in the book alley. It is said that only after you understand it can you be qualified to read the detailed version.

Xie Sigui naturally also needs to learn economics and arithmetic, just like Xiao Hong is only adding and subtracting now, Tian Fang, Li Mi, Shao Guang, Equation, Pythagorean... don't even know how to read, they can't understand it, even better than the Four Books and Five Classics bible.

He Xichao said: "Well, Dad taught me some things before."

How long ago was it, four or five years old?

Xie San shook his head and walked into the front yard.

Xie Er is much older than Xie San San, with a small beard on his chin, listening to his younger brother's intentions, looking at He Xichao who is tightly wrapped, his small face looks even smaller.

He didn't say anything, just asked: "There is a round field today, [-] steps a week, and [-] steps in diameter. How much is the field?"

He knew that he would take the exam first, but even if Yuan Tian came here, it would be too much. Xie San couldn't help but slander his second brother from the bottom of his heart, and when he turned around to remind He Xichao, the child promised to come out.

"About 75 steps." The voice was crisp and crisp.

Xie Er nodded, "Why an appointment?"

"The round ratio is not three, but a little more than three."

As soon as He Xichao said this, Xie San saw that his second brother's casual eyes changed instantly, a little, um, frantic.

"What's the round rate, big brother?" Xie Sigui asked.

Xie Siyuan shook his head: "I don't know either."

"The number of round noodles must not be less, and you will know when you learn Fang Tian in the future." Xie San explained.

To be honest, he didn't know that the round rate was not three!

Xie Er got up, walked back and forth in front of the table, and then continued to ask: "Today, there is a household whose height is more than six feet and eight inches in width, and the distance between the two corners is about ten feet. Ask the height and width of the household."

He Xichao frowned slightly on this question, but it involved solving quadratic equations in one variable and the Pythagorean Theorem, which is equivalent to junior high school mathematics.

The general idea of ​​the topic is: a rectangular door, the height is 6.8 feet more than the width, and the diagonal is 10 feet long, so what are the height and width?

According to the Pythagorean theorem of right triangles, the square of the height plus the square of the width is equal to the square of the hypotenuse. Let the width be x and bring it into the equation to solve it.

"Second brother, isn't it too difficult?" Xie San couldn't help but say.

Xie Er glanced at him, "It's really difficult for you."

Xie San: "..." Most people can't do it, okay?

Looking at the two fourth generations of the Xie family, they didn't even understand what they meant, so they were too embarrassed to ask.

Their eyes fell on He Xichao, and they saw him walk to the table, raised his head and asked, "Can I borrow a pen and paper to do the math?"

"Please."

He Xichao picked up a pen and directly listed the equation. The width is x, and the height is naturally x+6.8. The sum of the squares of the two is 100. When x is calculated, there are two solutions. The first is 2.8, and the second is - 9.6, remove unrealistic negative numbers...

"It is two feet eight inches wide and nine feet six inches high."

Xie San: "..."

Xie Siyuan: "..."

Xie Sigui: "..."

The three of them looked up at Xie Er together, their eyes widened one by one, regardless of whether the answer was right or not, He Xichao felt that it was right if he could say it.

Xie Er looked at He Xichao steadily, and said, "Very good, very good."

The three of them leaned down on the table together to watch He Xichao's writing process, and then...

Xie San asked: "What is this writing, Second Brother?"

Xie Er stroked his chin beard and stared at it for a long time, "I don't know either."

ha?

Xie Er ignored the three of them, and made a gesture of invitation to He Xichao, "He Xiaoyou, please come inside."

"Thank you, thank you...Second Brother." He Xichao almost called out from his uncle.

Xie Er glanced at Xie San and said: "The third child is here, so he is a generation shorter."

"Can this be my fault?" Xie San followed into the study, but he took a step before being stopped by Xie Er.

He said: "Take Siyuan with you, and go to play elsewhere, so don't disturb us."

Xie San was dissatisfied: "Why?"

"You don't understand anyway."

Xie San: "..."

Although Xie Er was born as a Jinshi, he still worked as the head of the household department for so many years, and he was not a big official.

Apparently he didn't have much interest in being an official, because he was a mathematics fanatic and devoted himself to studying his arithmetic.

But in this era when the Four Books and Five Classics are the mainstream, learning to multiply and divide arithmetic is already very remarkable, let alone the square root?If Xie Er hadn't studied it slowly by himself, who could teach him?

It is much more difficult to find a teacher of economics and calculation these days than a famous teacher of Confucianism.

I can also understand how there is a complete set of "Nine Chapters of Arithmetic".

But self-study has limitations after all, many problems cannot be solved, and looking at the capital, it seems that there is no one to study and discuss with, Xie Er is really lonely as snow, feeling that it is hard to find a bosom friend.

Then He Xichao appeared.

At the moment when He Xichao revealed the wide-ranging family, even though Xie Er didn't show it on his face, the joy in his heart was like a mountain spring and flowing water, uninterrupted.

That day, Xie San had no choice but to ask his second sister-in-law to come forward and let the second brother in the study release him.

It's time for dinner, his second elder brother won't die from starvation, but He Xichao is only so young, so he has to eat, what should Duke Wei do if he's starving?

Mrs. Xie Ershao was so angry and funny, she walked into the study, brought out a small one inside, and said angrily to her husband: "Everyone says that the Xie family treats people with courtesy, you are making the guests hungry What's the point of explaining it to you?" He took He Xichao's hand and said, "Go, ignore this idiot, the dinner is already prepared, Young Master He can use it casually, the hospitality is not good, please forgive me."

To be honest, He Xichao is really a little scared. People with the spirit of studying are too persistent. If you don’t understand, you can ask questions. It’s easy to say practical problems, but some calculation formulas just don’t have a reason, just memorize them. Then He Xichao had to follow the formula The derivation process is deduced again...

Usually when visiting guests, they come to the door in the morning, leave lunch, and say goodbye in the afternoon, but He Xichao was dragged by the host until after dinner, and when he returned to the Duke's mansion, it was completely dark.

After He Xichao left, Xie San took his notes and three articles to find his grandfather.

Xie Ge is over [-] years old, but his body is still strong. Although he occupies a high position, because of his rich life experience, his superior aura is restrained, which highlights the literati temperament, and he seems to have a sense of elegance and affinity.

"Siyuan and Sigui said, there is a little friend from your place. Not only is he surprisingly good at learning, but he can even compete with your second brother in arithmetic, but this one?"

"It's not a competition. The second brother said that those problems that have troubled him for a long time have been solved by Xichao's reminder, so Xichao's arithmetic should be better than the second brother."

Xie Ge nodded his head, turned on the light, squinted his eyes and looked at the article, with a slight surprise in his eyes.

"how old is he?"

"Just seven years old."

"Strange talent."

Xie Ge's evaluation was very high, Xie San didn't think it was wrong, he said: "Xi Chao is going to take the examination in the next year."

"From the point of view of this article, the topic is profound and the thinking is meticulous. Apart from the need to refine the words and sentences, it is a masterpiece. It can be the leader in the college examination."

With Xie Ge's knowledge and status, as soon as these words came out, it almost predicted He Xichao's college entrance examination results in the next year.

Xie Sandao: "This is done by him independently, no one guides him."

"Xiu Ning, do you want the old man to take him under?" Xiu Ning is Xie San's word.

He said: "Grandson has this intention. With Xichao's ability, the Xie family will not be able to find a suitable candidate except you, not grandson, and father is the same. Grandfather, do you think so?"

Old Xie Ge nodded slightly, but he hesitated.

Xie Ge’s old peaches and plums are all over the world, but there are not many students who really worship tea and learn from teachers. They can count on one hand, and they were accepted in the early years. After entering the cabinet, their vision will be even higher. one.These students are now in important positions in the court, they are all outstanding, the emperor is young and promising, it is the time for employing people, and the future is bright.

To be honest, although he had never met He Xichao, he was moved by someone who could write such a profound article, even if he was not seven years old, or as old as Xie San, in terms of vision.Such a good seedling has unlimited potential, and he really wants to take him in as an apprentice.

However, Xie San may not pay attention to government affairs, but he knows that Wei Guogong's only two grandsons are accompanied by the prince.

Old Xie Ge is different from Wei Guogong, he is not a relative, the emperor trusts him, let alone have anything to do with the prince.

Even if he has the title of Prince and Taifu, it has nothing to do with the prince, it is just an honor bestowed by the emperor.

After weighing it over and over again, he shook his head and sighed, "It's a pity."

Xie San didn't know what he meant, but nodded seriously, "It's a pity indeed, I told him that I wanted to recommend it to you, but he refused on the spot."

Hearing this, Mr. Xie Ge looked over, "What?"

Xie San said: "Grandfather, that kid is very proud, saying that he has no plans to be a teacher for the time being, even if he wants to be a teacher, he has to see if he likes the teacher, otherwise he will not want it no matter how talented he is."

Mr. Xie Ge finally turned cold, "Arrogant boy!"

"It's crazy enough, but it's true, so my grandson left first." Xie San bowed and said, "Oh, by the way, my grandson has to take the notes and articles back to have a look. After three days, Xi Chao will return. Next, let’s discuss with him when we agree.”

However, Mr. Xie Ge put it on his book and said: "Let's put it away for now."

"grandfather?"

"With your level, what can you comment on? Words or sentences?"

Xie San: "..." He was despised twice in a row today, really!

"That's all you can see." Mr. Xie Ge waved his hand, "Let's go, I'll pick it up tomorrow.

The author has something to say: Everyone was stunned...

Yao: Are you very proud and proud?

He Xichao (contemptuously): What is there to be proud of when standing on the shoulders of giants? What about mine?

Yao: The system, book travel, space, abilities... do not match this article

He Xichao: Get lost
