"Let's not talk about anything else, let's think about what kind of problem to propose", Lu Xun said, he was more concerned about his sister than those who ate, and wanted to determine what the problem was as soon as possible.

"What do you think of pi, I don't think anyone can calculate the problem of pi, beyond the products of several eras, if the people of this era are really so demonic, let's not mix up, just find a thick thigh to hold", Bei Mo first raised a question, a lot of people talk about pi, Bei Mo remembers very well that when those protagonists studied pi, the world shook, and all directions worshipped, so Bei Mo first thought of pi.

"Bei Mo, do you think Ziyan can calculate pi Even if she knows the answer, she doesn't know how to calculate it, not to mention that what she hates the most is mathematics, I think pi can be memorized to the second decimal place at most, no more", Liu Yi vetoed, pi is indeed difficult, he can guarantee that it is really impossible for anyone to study pi in this era of the Three Kingdoms, but others can't study it, Ziyan can't study it, she can only say three points and four, others ask her how to calculate it, it's embarrassing, There's no way to explain it, and no one will believe her then.

"Ziang is right, pi is not good, mathematics Ziyan is not interested in it at all, it will be bad if she is suspected at that time, think about one and think again", Lu Xun also refused, they don't understand mathematics, and if they can't give the world a convincing answer when the time comes, it will be miserable, and the problem of pi is too difficult, and when the time comes, others can't understand the solution, and no one can recognize it.

"Do you remember the problem of chickens and rabbits in the same cage that gave us the most headache when I was a child, I also asked Ziyan for advice at that time, in the end we were both stumped, and it was not solved until we learned the binary equation later", Liu Yi said with a smile, the chicken and rabbit in the same cage can be said to be an indelible shadow in the hearts of primary school students, Ziyan must be impressed, and this question is more close to the people, presumably many people will be interested.

"Chickens and rabbits are in the same cage, there are three hundred and sixty legs, one hundred heads, how many chickens and how many rabbits, is this such a problem", Bei Mo said, indeed this kind of problem has been encountered by everyone in elementary school, and at that time I was so anxious that I couldn't think of it, in this era, no one should be able to calculate it, Bei Mo nodded and agreed.

"Yes, this kind of problem Ziyan should be able to solve, the binary equation is ripe in high school, she is about to graduate from college, there must be no problem, but there is another point, what if someone really catches chickens and rabbits and puts them in the cage to count them out, so we should state that if you say the answer, then you must say the process of solving the problem", Lu Xun is also more satisfied with the question raised by Liu Yi, before the binary equation is not learned, you will feel that this problem is rare, but after learning the binary equation, This becomes very simple, people in this era will not be so evil that they can even learn binary equations by themselves, this kind of knowledge is summarized after several generations of wisdom, even if you have enough IQ, you will never think of this aspect, so the people who really know the problem-solving skills should be the four of them in this era.

"Then it's decided, when I go back, I'll spread the news, you can also help, the Lu family is not small, if you get involved, it will definitely speed up the process, and Bei Mo, haven't you been traveling with the teacher all the time, take it out and publicize it wherever you go, let's work together, I believe that soon this problem will become a nightmare for the strategists in the Three Kingdoms era", Liu Yi wanted to laugh when he thought of that kind of scene, the top strategists are very good at strategy, government affairs, and leading troops, but a math problem gives them a rare headache, It must be interesting to sit at the table and go crazy.

"Then please Ziang", Lu Xun bowed his hand and saluted.

"Uncle, the three of us don't need to care about these red tapes together, and thank me for what, it's only natural for me to find my daughter-in-law", Liu Yi hurriedly supported Lu Xun and said with a smile.

"You kid, you don't have any seriousness, what do you call your daughter-in-law, I don't agree, the eldest brother is like a father, although Ziyan's parents are not here now, her brother is still here", Lu Xun scolded with a smile and said, Liu Yi's temperament is also very clear, he is never ambiguous when doing business, but in ordinary times, he is not in tune with it.

"Uncle, Zi Yan and I are in love, you can't beat the mandarin ducks", Liu Yi said lightly, I can be together in the last life, and I must be in this life, Zi Yan is waiting for me.

"Is that what happened to Cai Wenji, I heard some rumors, you are now a Jinwu Zangjiao, I won't stop you, can you have three wives and four concubines, Ziyan is not as friendly as the thoughts of ancient women", Lu Xun glanced at Liu Yi and said, he was actually quite satisfied with Liu Yi, but he had to knock and knock, he had only been in this world for a long time, and he had a leg with Cai Wenji, and he didn't go to heaven if he didn't knock and knock.

"Uncle, don't wronged me, Miss Cai Wenji was handed over to me by Uncle Cai Yong, she can get married, I am just equivalent to a guard, and now the rumors are all people who don't know the truth and then ruin my reputation", Liu Yi immediately exploded when he heard it, he and Cai Wenji were really innocent, how could it be spread to the point that the golden house was hidden, if Ziyan heard the news, he would not be able to wash it by jumping into the Yellow River.

"I don't care, you can explain to Ziyan when the time comes", Lu Xun looked like a scoundrel, looking at Liu Yi's appearance, he shouldn't be lying, that is, he really has nothing to do with Cai Wenji, but who can guarantee that Ziyan will not think much after hearing about it, let them get rid of the matter between lovers, he, as an elder brother, just needs to ensure that no one forces his sister to do something he is unhappy with.

"I believe Ziyan will understand", Liu Yi said stubbornly, now his yard still leads to Cai Wenji's yard, Liu Yi doesn't dare to think about what will happen if Ziyan sees that gate, no, no, go back and block it, and go to the main gate to find Cai Wenji in the future.

"Hopefully, by the way, Bei Mo, who is your master", Lu Xun asked, without striking at Liu Yi's illusions.

"My master's name may not be clear to you, but one of his disciples should be known to you, Sima Yi's character Zhongda, is my senior brother", Bei Mo said with a smile on his face, Sima Yi's name should be like thunder, after all, Zhuge Liang survived, and he was a winner in life, creating the Jin Kingdom, ending the chaotic era of the Three Kingdoms, and interpreting a Gou character to the fullest.

"What, that little kid is Sima Yi or your senior brother" Liu Yi suddenly reacted that the old man seemed to be followed by a little kid, at that time, Liu Yi's mind was on Bei Mo, he didn't care about the little kid, he didn't expect that he was the future founding emperor.

"Yes, who let me get started later than him, but although my senior brother is young, his IQ is very high, and I can barely be beaten by relying on my thousand-year-old wisdom, especially when it comes to governing the country, I am willing to bow down", Bei Mo said with a wry smile, it turns out that your senior brother is still your senior brother, although he is familiar with the history of the Three Kingdoms, but he really doesn't understand the art of war, governing the country and the people, and he doesn't understand it at all, so he can suppress Sima Yi in the general trend of the world, and the others are not as good as Sima Yi, the more he learns from his teacher, the more he understands the importance of those things.

"Is it so exaggerated, I haven't met a top strategist yet, and I am more and more yearning for the era of the Three Kingdoms", Lu Xun said expectantly, he has been building ships behind closed doors at home, and he has never met a famous person in history.
