Carefree Prince In Tang Dynasty

Wang Wenjian didn't expect that he would be robbed by Li Xin, and his face immediately turned red and white.

Cui Wenyuan saw that his partner was rendered speechless by the king of Chu's words, so he immediately stood up and said, "If the official has any questions about the collection of classics and history and is troubled by His Royal Highness the King of Chu, the official will definitely kneel down without saying a word. Ask the King of Chu humbly for advice. However, the King of Chu asked such a strange question that no one has ever seen before, please forgive me for being hard to believe!"

Li Xin laughed loudly and said, "You are funny too. Let me ask you, why did His Majesty send you two here?"

Cui Wenyuan and Wang Wenjian didn't answer.

"It doesn't matter if you don't tell me, it's not that I don't know." Li Xin shook his head and said, "Didn't you two be sent to learn double-entry bookkeeping and Dashi characters from me?"

Cui Wenyuan and Wang Wenjian still refused to fight. They didn't know why Li Xin suddenly changed the topic to this place, and they always felt that there was a trap in this remark for them to fall into, so they unanimously chose to remain silent.

"Zi used to say that" Li Xin said this, and suddenly remembered the classic image of a scholar in the TV series he had watched in his previous life, and couldn't help secretly regretting: I can never go back to that weird, convenient and free world!

He shook his head, drove away the useless sadness, and continued: "Threesomes, there must be my teacher. Since His Majesty sent you to learn from me, you should follow his old man's order and respectfully respect me. Please advise. But you just said that you are unconvinced?"

Li Xin paused for a moment, showing a sly smile: "Could it be that you don't actually want to learn from me, even if you follow His Majesty's orders on the surface, you still resist in your heart? What is this called? Oh, yes, Yang Feng Yin Violation! Right? Is Yang Feng Yin Violation?" He glanced at Wang Gui, as if he wanted to seek some approval.

Wang Gui replied with a smile: "This old slave is illiterate, so I don't know if it's right. The prince should ask these two officers."

Cui Wenyuan's face turned blue and white. As the so-called heaven, earth, monarch, relatives and teachers, apart from heaven and earth, for Confucians, the king is the greatest. It is not a good thing to obey the king's order and violate it. If it was a different occasion, Cui Wenyuan would have to refute himself even if his heart was true.

But now, he can't seem to find a good way to explain it to himself. Because Li Xin accurately grasped his words, fast, accurate and ruthless.

Is this really that dandy King Chu who drinks and plays hooligans all day long?

Both Wang Wenjian and Cui Wenyuan had such doubts in their hearts.

Looking at the two people in front of him who were speechless by what he said, Li Xin nodded with satisfaction, and then said with a smile: "Chicken and rabbits are in the same cage, as many rabbits as chickens. Monks share bowls, as many monks as bowls. What do you think? Such a question is very strange, unheard of, unseen, isn't it?"

This kind of topic that even elementary school students can calculate in later generations is also considered a strange problem? Are you kidding me, then if you get to know Xiao Ming who is pouring water into and out of the pool at the same time, you can't just strangle yourself to death?

Wang Wenjian hesitated for a moment, but still boldly replied: "Yes! Dare to ask King Chu, are the chickens and rabbits in His Highness's house locked in the same cage? What's the point of asking such a question?"

Li Xin sneered, shook his head and said, "Meaning? You tell me the meaning? Yes, to tell you two frankly, this question just doesn't make any sense. No fool would be so stupid as to put a chicken and a rabbit in a cage." However, the two of you can’t even calculate this kind of problem that is completely meaningless and purely used for practice, do you still think that you can calculate it if you change it to a really meaningful problem?”

Cui Wenyuan suddenly felt a chill in his heart, but saw Wang Wenjian who was beside him had already been a newborn calf and said to Li Xin fearlessly: "Dare to ask Your Highness to come up with a test."

"Okay! You still have some guts." Li Xin smiled.

Cui Wenyuan shook his head silently in his heart. He didn't intend to think about it anymore, because he knew that he would definitely not be able to think of it. But listen to it anyway.

Li Xin said slowly: "Well, let's say that the Tang Dynasty and the Turks are at war today. The two of you are in charge of logistics and are responsible for escorting food and grass to the front. As we know, the food transport team is not transporting food. At that time, they could move 20 miles forward every day. After that, every 10,000 catties of grain and grass they brought would reduce their travel by 5 miles a day. Excuse me, if the grain transport team wants to transport the most grain and grass to the front line in the shortest time, they should carry grain How much is ten thousand catties?"

Li Xin casually made up a quadratic function problem. If it is put into later generations, a random junior high school student may be able to figure out the answer: when transporting 20,000 catties of grain and grass, this function achieves the maximum value.

However, this kind of problem is true for Cui Wenyuan and Wang Wenjian. Um, don’t forget about it. If you give him a draft paper, he doesn’t even know where to start.

It would be easier for Cui Wenyuan to give up directly. Wang Wenjian closed his eyes and thought about it for a long time. Although he didn't know what he came up with, judging by the cold sweat on his forehead, he probably didn't come up with anything useful.

After a while, Wang Wenjian finally opened his eyes, his expression was gray and defeated, like a rooster who had lost the fight.

"How is it? Is there any practical significance? Have you calculated the result?" Li Xin asked with a smile.

Wang Wenjian was silent for a moment, then cupped his hands and said, "I don't know that the king of Chu is so proficient in arithmetic, I feel ashamed. This time, I really surrendered." What else can I do if I don't admit defeat? You say that chickens and rabbits in the same cage are meaningless, it’s purely a weird question, and you can’t do it if it has practical meaning for you, so what else can you do? Even if you come from a wealthy family, you can't cheat twice in a row, right?

Cui Wenyuan also clasped his hands and said: "I am also convinced. The achievements of King Chu in the field of mathematics are only seen in my life."

Hearing this, Li Xin smiled silently in his heart. Indeed, with the mathematical knowledge in his mind, not only elementary functions, but also calculus line substitution and so on, let alone the number one person in the Tang Dynasty, the number one person in the world is no problem. After all, neither Leibniz nor Newton were born these days!
