Qin Yifan said to the 'microphone': "I asked this question and I promise to let him retreat instantly. I will never be shameless and bother you."

"Really?" asked the Ninth Princess, "Can you really guarantee that one question can make him retreat? I also think he is too annoyed and took me four times in a row."

"It must be like this." Qin Yifan said, "If he can answer one word, I will broadcast the daily five-speed electric fan live."

"Qin Xianggong, what does the live broadcast of the five-speed electric fan mean?" An Lingxi asked strangely.

Wei Lan smiled but said nothing. Although he couldn't understand this sentence, he still knew it was definitely not a good word. It should be a slang. When he led the soldiers, he often heard them speak slutty and rudely.

He secretly wondered in his heart: Mr. Qin was so elegant that he could write a stunning poem such as the flying general of Longcheng, without teaching Hu horses to cross Yinshan, and was full of knowledge and could also say five-speed electric fans every day. Such a tiger and wolf word is really a person who is instant.

Of course, such talents are more real and down-to-earth.

If you only know elegance and not vulgarity, then you are the perfect saint who is only found in your fantasy. It is too fake. People are flesh and blood, and they must have all kinds of temperaments.

Some people have conflicting temperaments. Some people who are unforgivable actually have a kind side. Some people who are very kind in their minds also have evil thoughts in their hearts. There are only pure good and bad in their personality, and there are almost no such people.

I think Qin Yifan is even more cute. Although he is a national scholar, he is very suitable for making friends. He is not arrogant and cold, so people dare not date him.

"Jiu Sister, ask him this." Qin Yifan said: "The greatest is not outside, it is called 'big one'; the smaller is not inside, it is called 'small one. A foot of the sky is taken half of it every day, and it will last forever. Now there is a man who returns home from the city, travels half and then goes half. Isn't it impossible to reach this time?"

"Brother Qin, what exactly are you asking about this question?" Huang Yirong asked. She didn't even understand the question.

"Grandpa Qin, are you sure he can't answer this question?" An Lingxi asked.

"It would be strange if he could answer." Qin Yifan said.

This question involves a mathematical paradox. It has troubled the mathematics community for thousands of years. Only by understanding the limit theory can you solve it.

The mathematics in this world is still in the stage of addition, subtraction, multiplication and division. When talking about limits with them, they must be like listening to the heavenly book. They did not explain to the three people next to them. They explained to them that they were playing the piano about a cow, and even caused people who didn't understand it to argue.

In other words, if you want to understand this question, you need some knowledge. Those who don’t understand the key points only know how to argue.

...

On the school ground.

The Ninth Princess said, "Sima Daxian, you have already taken the exam three times in a row. Now I should be here to test you. If you can answer, I will give up directly. Otherwise, you will give up and stop bothering me."

"Please give the ninth princess a question." Sima Junyan said.

"This is the problem." The Ninth Princess thought for a moment, tried to remember what Qin Yifan said just now, and was afraid of forgetting it, saying, "The greatest is not outside, it is called 'big one'; the small is not inside, it is called 'small one. A foot of the sky is taken half of it every day, and it will last forever. Now there is a person who returns home from the city, travels half and then walks half. Isn't it impossible to reach this time?"

Sima Junyan was stunned when he heard this.

"The Ninth Princess is too difficult, I don't even understand it." said a general.

"A small one. a foot of the sky can take half of it every day, and it will last forever. This is certain. But if you go back and forth, it will be difficult to understand if you can never reach it." A civil official said. Civil officials must have some knowledge, and he still understood it after thinking hard.

On the other hand, although Sima Junyan felt that this problem was difficult, he still refused to admit defeat and worked hard to think about it.

"Why can't you never reach? Why? Where is the key to this problem? I know that it can't reach, but I don't know where it is wrong... What a mysterious problem, ten thousand times more profound than my research on numerology!"

If he can answer it, it will be a strange story in the world. The solution to this question is the limit theory, continuity and discontinuity.

Finally, a stick of incense passed.

Sima Junyan was still in place and could not give any answers. The crowd was surprised to find that all his hair had turned white.

White hair overnight?

He was originally an extremely smart person, otherwise he would not have been able to treat the astrology and was proficient in governing the country and taxes. His brain was very fast. Just now, because he was afraid of losing, he applied his mind and brain power to the extreme. It can be said that he really racked his brains.

So, in one incense stick of time, too many brain cells died and their hair turned white.

It's a waste of dyeing your hair.

"The Ninth Princess is so amazing. She actually made the enemy's head turn white for a stick of incense?" The crowd's respect for the Ninth Princess reached its peak.

"Sima Daxian, Sima Daxian?" Seeing that the time has come, the Ninth Princess had to try to wake him up.

After shouting for more than a dozen times, he finally woke Sima Junyan up.

"I, lost." Sima Junyan finally popped out of his mouth. Boom! His feet softened and he fell to the ground.

"yeah!"

The Ninth Princess jumped happily.

"That's great, we won!" After hearing the three words Sima Junyan said, many of the ministers of the Han Dynasty were filled with tears.

"It's not easy to make the barbarians admit defeat." A minister said excitedly, "He just asked the Ninth Princess four difficult questions one after another, and he was chasing them all the way. In the end, the Ninth Princess asked the difficult questions, and he also spent all his time thinking."

"The barbarians are a powerful country, and a tyrannical country is not so easy to defeat."

"The barbarians are very tough and arrogant at heart. It is not easy to make them admit defeat. In other time travel novels, the protagonist has two or three sentences and solved a few small problems and defeated the foreign envoy. It is too vague. What they wrote cannot compare to today's process."

"What's even more annoying is that they have read a lot."

"Actually, I haven't read it at all during this period. The key to proving it is still good is that there are fewer previous works. If I write later, it will become a trend in the eyes of others. Following the trend is garbage."

"Here's someone!" Gulihu shouted coldly, "Help Sima Daxian down and take good care of him."

He cursed in his heart: What kind of bullshit he is? He didn't even get a single question to test the other party's teenage princess. I really don't know why his father respects him so much. At best, he is just a traitor from Daxia. He is just a waste like other Daxia people.
