After Wang Shuang woke up, he immediately felt that he was different from before, he was grateful to Liu He, and his loyalty was immediately increased to 200, and he became a fierce general under Liu He's account.

After Wang Shuang left, Liu He immediately ordered someone to invite You Heng.

However, when You Heng heard that Liu He had just sent an ordinary soldier to invite him, he was immediately a little unhappy, and said lightly: "Shouldn't Duke Qin personally invite a talent like me?" ”

The soldier's face turned cold, but in view of Liu He's orders, he did not say anything to respond, but stood there quietly, waiting for You Heng's choice.

Seeing that his words were not answered, and he didn't want to talk about it with a big soldier, so as not to lose his worth, you said to yourself: "I'll go and see your Duke Qin, show him his great talent before leaving, and let him regret treating me like this." ”

Then You Heng came to Liu He's mansion with Liu He's personal soldiers.

After You Heng saw Liu He, he didn't salute, but just bowed his hand slightly, sang and said: "You Heng has seen Qin Gong, Su asked Qin Gong Lixian, it's just like this when I see it today, hehe." ”

Liu He said lightly: "It is true that I have always been courteous to Corporal Xian, but I only salute Corporal 'Xian', but I have never been polite to people who are not virtuous. ”

I saw You Heng say proudly: "Astronomy and geography are all incomprehensible; Three religions and nine streams, omniscient; The upper can be to the gentleman as Yao and Shun, and the lower can be worthy of Confucius and Yan. How can you talk about it with the vulgar! ”

"Hehe, what a big breath, since that's the case, I'll test you, you said that the three religions and nine streams know everything, and I ask you, how many disciples does Confucius have?" Liu He smiled faintly and asked.

"Haha, it's ridiculous to ask me such a low-level question, almost everyone knows it, there are three thousand disciples of Confucius."

"Oh? How many sages are there? Liu He didn't take his question as simple at all, and continued to ask.

"Seventy-two sages, everyone who has read the Analects knows this, don't you not even read the Analects?" You Heng laughed and said sarcastically.

At this time, not only You Heng, but even Liu and several literati around him looked at each other, why did their lord ask such a simple question? This kind of problem can be hit even by children who have just read a book for a few years, and if you want to embarrass you, I'm afraid it's not enough, right?

However, then Liu He's question made them stunned, only to see Liu He hehe smiled and said: "I'll ask you another question, if you can answer this question, I will be erudite, since you said that there are seventy-two sages among Confucius's disciples, let me ask you, how many children are among them, how many are they?" ”

"This ......" When You Heng heard this question, his face changed greatly, and he searched his stomach, but he couldn't find the answer, and finally he could only sneer at him: "This is the answer that no one can know at all, you are deliberately embarrassing people." ”

"How can no one know? It's that you didn't read well. Liu He glanced at You Heng with slanted eyes and said with a faint smile.

"Tell me, what is the answer? Is there a source? If you can say it, I will obey you. You Heng snorted and said angrily.

"There are clouds in the Analects, Mo Chun, spring clothes are completed, there are five or six champions, six or seven children, bathing in Yi, the wind is dancing, and the song returns to ......"

"Yes, so what?" You Heng was stunned when he heard this, and secretly said that this has nothing to do with the answer, right? The scribes present were also full of doubts, because they also did not understand what this had to do with the answer.

But he saw Liu He and hehe sneered: "Five or six, thirty, six or seven, forty-two, thirty plus forty-two is exactly seventy-two, so it is thirty adults and forty-two children, this is the disadvantage of you not seeking to understand when you read, you can't understand the sage's subtle words, and you dare to brag about it with me." ”

"Actually, there is such an explanation", when You Heng heard this, his face immediately turned red, and he wanted to refute, but he had nothing to say, because sophistry is also an ability at this time, not to mention that this cannot be regarded as sophistry, but this does not mean that You Heng will be convinced, he snorted coldly: "This is just a coincidence." ”

"Since you are not convinced, then let me ask you another question, there are ten birds in the tree, and I killed one with a bow and arrow, how many are left?"

"Haha, this kind of arithmetic is simply too low-level, of course there are nine left." You Heng laughed and said disdainfully.

"Wrong, one bird was shot to death, and the other birds couldn't escape? You're so stupid, you're not as smart as a bird, you stupid bird, you're still boasting about it. Liu He said with a look of banter and mockery.

When You Heng heard Liu He's ridicule, his face turned purple, but he felt that this was still Liu He's sophistry, so he said loudly: "You are still sophistry, you can't get on the stage, and the capable one will give me an arithmetic problem, if I can't solve it, then you win." ”

"Okay, then I'll give you a real arithmetic problem." After Liu He finished speaking, he took out his sword and drew a nine-square grid on the ground, and then said: "You only need to fill in the nine numbers from one to nine, each number can only be used once, so that the three numbers whether it is vertical and horizontal, or oblique, add up to fifteen, and I will count you as if you pass the level." ”

"This and this, this ......" When You Heng heard Liu He's words, his face suddenly turned pale, and he muttered: "Isn't this Luoshu?" Zheng Kangcheng, who died not long ago, once proposed that Taiyi take its number to line the nine palaces, and the four positive and four dimensions are all combined into fifteen, but he did not say a specific method, I have been calculating for months but can't find the answer, could he calculate it? ”

Liu He naturally heard You Heng's words, and also saw his expression, secretly funny, but on the surface, he said, "How? You might figure it out? How about I give you three days? ”

You Heng smiled bitterly: "Don't say it's three days, even if I can't calculate it in three months, this topic is too difficult, I really can't calculate it, but can you calculate it?" ”

When Liu He heard this, he laughed and said, "This matter is very simple, I will do it easily." ”

After finishing speaking, Liu He raised his sword, brushed and wrote on the ground, and then said with a smile: "You come to verify, is it correct?" ”

You Heng hurriedly stepped forward, calculated carefully, and then said with a look of disbelief: "I didn't expect you to really calculate, this, this, it's just ......"

"Hey, what's this? The number of the nine palaces, two and four for the shoulder, six and eight for the foot, three on the left and seven on the right, one on the nine, and five in the center, I can not only calculate, but even create the formula. You Zhengping, are you convinced? Liu He looked at You Heng's sweat and asked with a loud laugh. For mobile phone users, please browse M. Reading for a better reading experience.
