The salted fish life of the door-to-door son-in-law

"Heh, the tone is not small. Come on, I have a problem here. I have been studying it for more than a year. As long as you can help me solve it, I will admit that I am not as good as you! How about it!" The old man directly patted Xiaoben said to Liu Zhicheng.

"Too lazy to move." Liu Zhicheng would not use his brain for no reason, that would be a lot of trouble.

"You!" These words made the old man very angry. The old man had lived for more than 70 years, and he had never seen such a young man who dared to speak big.

"What are you doing at school? Waiting for someone, right?" The old man deservedly lived for a long time, and he could see Liu Zhicheng's purpose at a glance.

"That's right, wait for my wife." Liu Zhicheng continued to reply lazily.

After hearing Liu Zhicheng's words, the old man said with disdain: "Young man like you can still find a wife, it's simply God's eyes."

These words made Liu Zhicheng open his eyes and look at the old man again, then Liu Zhicheng said to the old man with a smile: "It's not that I don't want to answer your question for you, I also read it just now, the question that has troubled you for more than a year is simply a joke, That problem is just a logical problem, which can bother you for more than a year? I think you are not too young, if I solve it for you in minutes, I am afraid to hit you, in case I hit you badly Come on, who is in charge?"

"Little Huangkou, when you said this, did you ever think that you are responsible for what you said?" The old man stood in front of Liu Zhicheng and said to Liu Zhicheng.

"Hey, come on, give me the notebook, and I'll give you the answer, but I have to tell you in advance, in case you get hit and your heart can't take it, I don't care!" Liu Zhicheng said to the old man.

Hearing Liu Zhicheng's words, the old man put his little notebook directly into Liu Zhicheng's hands, and said to Liu Zhicheng: "You can rest assured, as long as you can solve it, not only will my heart not be overwhelmed, I can even give you a copy of it." The title of professor at Kyoto University."

After hearing this, Liu Zhicheng waved his hands, then took the old man's small notebook, and said to the old man, "Forget it as a professor. I'm a lazy person, so for teaching and educating people, you should hire someone else."

说完刘志成便看了一眼题目，老者本本上记载着：阿尔贝茨和贝尔纳德想知道谢丽尔的生日，于是谢丽尔给了他们俩十个可能的日期：5月15日、5月16日、5月19日、6月17日、6月18日、7月14日、7月16日、8月14日、8月15日、8月17日。谢丽尔只告诉了阿尔贝茨她生日的月份，告诉贝尔纳德她生日的日子。

Alberts said: "I don't know Cheryl's birthday, but I know Bernard won't either.Bernard replied: I didn't know Cheryl's birthday at first, but now I do.Alberts also replied: Then I know too.So, when is Cheryl's birthday?

After Liu Zhicheng glanced at the question, he asked the old man with some uncertainty: "Are you sure that this problem has troubled you for a year, you know, when I was in the third year of high school, I already knew how to solve it." gone."

After hearing Liu Zhicheng's words, the old man was obviously a little angry. He said to Liu Zhicheng: "Little friend, why are you talking so nonsense? This math problem is a worldwide math problem. So far, no one has solved it." If you can solve it, you actually say that you can solve it in the third year of high school, it's just nonsense."

Liu Zhicheng was very speechless after hearing this, because what Liu Zhicheng said was indeed the truth. In a certain life, he had exactly the same question, but Liu Zhicheng answered this question in his third year of high school.

Seeing that the old man didn't believe it, Liu Zhicheng simply said nothing, lowered his head and began to write the answer, and worried that the old man would not understand, Liu Zhicheng also deliberately wrote out the process.

Chapter 922 Worldwide Math Problems

Soon, Liu Zhicheng wrote out the answer.

Among the ten days that appeared, only the 18th and 19th appeared once. If Cheryl’s birthday is on the 18th or 19th, then Bernard, who knows the date, can guess the month. He must know when Cheryl’s birthday is. What month and what day.

Why is Alberts sure that Bernard doesn't know Cheryl's birthday? As mentioned above, because both May and June have the 5th and 6th that only appear once, Alberts who knows the month can judge, Whether Bernard is sure, so her birthday must be in July or August.

Bernard's words are also informative, because out of the remaining 7 days in July and August, only the 8th occurs twice, if Cheryl tells Bernard that her birthday is on the 5th, Bernard It was impossible to guess her birthday based on Alberts' words.

So there are only possible days left on July 7, August 16 and August 8.After Bernard spoke, Alberts also learned about Cheryl's birthday, reflecting that Cheryl's birthday month cannot be in August, because there are two possible days in August, but only one possibility in July.

So the answer is July 7th.

After Liu Zhicheng finished writing, he handed the notebook directly to the old man, and said to the old man, "I've written it in great detail. If you still can't understand it, don't blame me."

After speaking, Liu Zhicheng closed his eyes, leaned on the back of the chair and continued to doze off, while the old man took a small notebook and studied it intently.

I don't know how long it took before Liu Zhicheng fell asleep. The old man finally understood it. He suddenly realized that the way he looked at Liu Zhicheng changed. This problem is a worldwide academic problem in this world. The next year's young man was solved, which shocked the old man.

At this time, Zhou Xiafei also rushed over after class. After seeing the old man, Zhou Xiafei greeted the old man respectfully: "Principal, are you researching the subject again?"

After finishing speaking, Zhou Xiafei saw Liu Zhicheng leaning on the chair, kicked Liu Zhicheng, and said to Liu Zhicheng: "Get up, I don't know how to say hello when I see the principal, and I'm still sitting on the chair like an old man!"

The principal was taken aback when he saw Zhou Xiafei's action, and asked after a while: "Young man, the wife you are waiting for is Professor Zhou, right?"

Zhou Xiafei, as a professor of this school, naturally knew him as the principal, so the principal said to Liu Zhicheng.

"That's right, my wife, isn't she beautiful!" Liu Zhicheng stood up, took Zhou Xiafei's hand, and said to the old man.

"It doesn't matter whether you are pretty or not, young man, do you know what it means when you solve this problem?" The old man asked Liu Zhicheng.

Liu Zhicheng waved his hand indifferently, and said to the old man: "I don't care what it means. Besides, such a topic may be difficult for you, but it is too simple for me."

After Liu Zhicheng finished speaking, Zhou Xiafei held Liu Zhicheng's hand. He hadn't noticed before that Liu Zhicheng still had the habit of bragging.

"Okay, okay, young man, I have another question here, which has troubled the whole world for a long time, I don't know you..." Before the old man finished speaking, Liu Zhicheng directly pulled Zhou Xiafei away.

Before leaving, Liu Zhicheng said to the old man: "I am here to accompany my wife, but I don't have time to help you answer questions." After speaking, Liu Zhicheng took Zhou Xiafei away.

But since the old man knew Zhou Xiafei, and that young man was Zhou Xiafei's husband, he naturally ran away from him. The old man smiled and left with confidence.

Liu Zhicheng dealt with matters with the Dianxing faction at night, and stayed with Zhou Xiafei during the day. Five days passed like this. Just today, a big event suddenly happened at Kyoto University, that is, a world-renowned mathematician, Rajskoff visited Kyoto University with his apprentice Will James.

If you say visit, just visit. He also proposed a conjecture. In fact, this conjecture has been proposed a long time ago. Once it was proposed, it was immediately rated as one of the top ten mathematical problems in the world.

Challenge Kyoto University with your own worldwide academic problems. Although Kyoto University can be said to be the highest-level institution in China, the teachers and students there are still a little embarrassed when facing the world's most difficult math problems, because they can't solve them at all. come out.

In fact, even Rajiskov is just a conjecture on this question, but he has conducted many researches and came up with an answer, but the answer has not yet been announced.

Seeing that no one at Kyoto University could confirm his conjecture, Rajiskov planned to give a speech at Kyoto University to explain his research to the majority of students.

In fact, he came here for one more thing, and that was about Zhou Xiafei. His apprentice was fascinated by Zhou Xiafei, and Rajiskov heard that Zhou Xiafei was a professor at Kyoto University, so Rajiskov wanted to come here. Match match two people.

When the president of Kyoto University heard this, he waved his hand directly and said to Rajiskov: "I'm very sorry, although I shouldn't interfere too much with young people's affairs, but I'm sorry to tell you , Professor Zhou is married, and her marriage partner is not simple."

Mentioning Zhou Xiafei's husband, the president of Kyoto University immediately remembered that this kid is not simple. If he is hired as an honorary professor of Kyoto University, can he be asked to give Rajiskov's conjecture to Kyoto University? Proven.

After all, Liu Zhicheng's strength was personally seen by the president of Kyoto University. In just a few minutes, he solved the problem that had troubled him for many years. So if Zhou Xiafei's husband took action, maybe he could really solve it. At that time, Kyoto University will become famous in the world, and its name will be preserved in history.

Therefore, the principal of Kyoto University said to Rajiskov: "We have a young man here who is very good at mathematics research, and he is also Zhou Xiafei's husband."

Will James, who was standing next to Rajskov, didn't care at all when he heard that Zhou Xiafei was married. He said to the principal of Kyoto University: "I don't mind that my goddess is married, as long as I get her People are fine, I don't care about the rest!"

These words directly made the president of Kyoto University a little unhappy, but he was not happy, he still had a demeanor, after all, he was the president of Kyoto University.

"Then let him try it out, whether he can prove my conjecture. If he can prove it, I will return to my country immediately, and I will never set foot in China again in my life."

"Well, let me try and see if I can call him."

Chapter 923 Ask Liu Zhicheng to make a move

"Professor Zhou, I called you here this time because I want to ask Professor Zhou for help."

The principal of Kyoto University specially called Zhou Xiafei to his office, and said to Zhou Xiafei with some embarrassment.

Although Zhou Xiafei was a teacher at Kyoto University, Liu Zhicheng was not, so if Liu Zhicheng was to come to help, he could only go through Zhou Xiafei, and Liu Zhicheng might not be willing.

"Principal, just tell me if you have anything to do. What can I do for you?" Zhou Xiafei said to the principal strangely. She knew nothing except music and acting, and in these two areas, the school had many expert teachers. So there is no need for Zhou Xiafei to come forward.

"Who is your husband? He must be very good at mathematics research!" The principal asked tentatively.

This question confused Zhou Xiafei, because Zhou Xiafei didn't know that Liu Zhicheng was good at mathematics. Liu Zhicheng beat people very well, and Liu Zhicheng's poems were also quite good, but in terms of mathematics, Zhou Xiafei really didn't know what Liu Zhicheng's level was. .

So Zhou Xiafei said to the principal with apology: "Sorry, principal, I really don't know what my husband knows?"
