Of course, whether he is a bandit or a mountain captain, it has nothing to do with Yang Yuying, but the old man "coveted" Yang Yuqing's "Fengshui Treasure Land" and insisted on betting with her that whoever wins will take up the place to fish.

Yang Yuying is really over the age of fighting for this, so of course she took the initiative to stand up and give way. But she was unhappy and unhappy. It seemed that it was not something she had taken seriously, so the old man couldn't enjoy it.

The so-called "old and young" are the younger and younger, which is probably the case.

That's right, she was idle anyway, so she teased the old man for a while and smiled and made a bet, but she let the old man gamble whatever he wanted.

If you say something else, Yang Yuying may not win. When she was in Dashun, she was always entangled in the inner house and never even attended the Zhengjing Academy. Later, the court held a university, and she just looked at it and sighed. It was because she heard that Zhao Jin was admitted to the medical school.

As for going to the interstellar world, it is mainly about playing.

In the east, Danqiu and the west Taihua, traveling to the north sea and the evening of Cangwu, is free.

However, as an intelligent life, you must have to learn some skills more or less, after all, it is easy to learn.

At this moment, the old man insisted on betting with her to solve the problem, and the math problems were solved. He asked each other to see whoever couldn't solve it first would lose.

Yang Yuying: “…”

The old man knelt on his knees, straight, stroked his beard and laughed, looking at himself: "Don't say grandpa, I bully you junior, I'll just show you what my nine-year-old grandson would do..."

Then he asked: There are people in the stable, and there are also horses, with a total of 22 heads and 72 feet. How many people and horses are there in the stable?

If Yang Yuying didn't know how to calculate this kind of chicken and rabbit in the same cage, the Marshal would be so angry that he would jump out of the coffin... and destroy all those who saw this scene, so that she would not be ashamed to see people.

So, after the old man finished talking about the question, before he could say anything, she stuffed fish into the fish basket and laughed: "14 horses, 8 people."

Old man: "…"

Yang Yuying answered her questions very quickly, but the old man couldn't answer them so quickly. He always had to hold an abacus, a pen, ink, paper and ink, and lie on the stone for a long time.

However, this old man is indeed knowledgeable, has considerable research on Western learning, and has advanced methods to solve mathematical problems. He is both spiritual and patient. No matter how slow he does the questions, he is serious and meticulous.

Now that we have an old account and don’t know how to use Arabic numerals, the old man in front of us is definitely a fashionable gentleman.

After most of the day of Q&A, the old man became more and more excited, his eyes shining. When she was gnawing, she glanced at him and almost thought she had attracted a wolf.

Two days later, the old man was finally stuck with a question.

Yang Yuying also asked casually - from zero to billion, write down all integers and find the sum of all numbers.

If you have done this kind of tricky questions well, you know the routine, and any citizen with a normal IQ and who knows the school of the Middle Ages can get results by simply calculating it. The problem is that the old man from the ancient times must have never received the cramming education and question-season tactics of the Middle Ages, and he has never seen countless brain teasers and interesting math questions and answers.

She didn't care at first, but when she came back to her senses, she found that the old man was squatting on the ground, holding a branch and gestured with all his heart. Sweat rolled down, wetting the land in front of her a lot.

Yang Yuying didn't move her eyes, and she was also shocked, afraid that he would be too exhausted and get out of trouble.

In his fifties, he was in the interstellar era. He was a young man in his prime, but at Dashunchao, he was already old and had a lot of diseases. Yang Yuying saw that his lips were black and his nails were purple, which was not very healthy.

"Old man, I am a poor man and I am a random question. I lose this round. The place will make you and the stone will make you. Otherwise, I will burn two more fish for you. Come and fish quickly. How about it?"

The old man didn't look at her, and didn't even glance at her: "The rules are my own. If the questions you asked did not break the rules, there would be no problem."

The breeze blew by, as if it was full of stubbornness.

Yang Yuying persuaded him several times, but he almost lost his skills. He tried his best to win over the woods that followed the old man. As a result, he threw all his charming eyes to the blind man. After a while, he changed his mind and simply ignored whether the old man wanted to know or not. He grabbed the other party's paper and pen and wrote the result well - 81×5000000001=40500000001.

"It's very simple. The first number and the penultimate number, the second number and the penultimate number, and so on, are divided into 500 million pairs, the sum of each pair is 81, and the sum of the last 100,000,000 is 1, that is, 500 million 81 plus 1."

The old man covered his ears and couldn't escape Yang Yuying's answer.

"So simple? It's so simple?"

The old man murmured to himself, happy and annoyed, as if he was filled with emotion, and then he was full of energy. His eyes lit up after turning around and his head lit up: "What else can I give it to me again? You little girl, although the questions you asked are not difficult, they are really interesting and interesting!"

Yang Yuying: “…”

Why don’t you give him a water inlet pipe? Is it a problem with the water outlet pipe? Is it a matter of whether he is tired of it?

The Marshal said that in the Middle Ages, primary school students and parents, were always restless because of horrible math problems, and were countless bald. If everyone had the enthusiasm of this old man for mathematics, wouldn't they all become mathematicians?

The old man's desire to learn is quite admirable, and Yang Yuying is so admirable that she wants to find a place to get up and never show up again.

Does she have no hobby for mathematics? Is the games not fun, or is the food not delicious? Practicing swords is better than playing math problems!

I am always pestered by an old man to ask new questions. Whoever feels it knows.

Yang Yuying was also questioned and had a headache, so she didn't struggle and let him lie down and let him do anything, but she couldn't take any advantage. She was all at a loss, which was not in line with her principles.

"Old man, I'm not good at interesting questions. If you really want to know, then you should exchange the knowledge I'm interested in?"

The old man immediately looked confident: "There are thousands of knowledge in the world, and I am only good at numbers and chess, but no matter what you want to learn, if you don't plan to read the secret book collection of the Mountain and River Sacrifice, or the Wanting Book Records of the Hanlin Academy, I can get a first-class secret book for you!"

"Okay, then let's have a gamble!"

Yang Yuying smiled, "No need to be too complicated. No, let's throw the coins."

Throw it in turn, and the person who throws it out first wins, and the person who loses loses a book to the other party. It is good for piano, chess, calligraphy and painting, and medicine, fortune-telling, and astrology. As long as the person who wins is interested, it is good.

After playing seven rounds, the old man lost everything. His hands trembled when he wrote the notes of debt. He was so angry that he wanted to cry: "Cheating, how did you cheat in a movie?"

Yang Yuying was also surprised, so she was not annoyed, and just smiled: "My grandpa, it's your luck that makes people hard to describe."

Seeing his angry look, Yang Yuying simply spread his hands and called the little shepherd boy next to him to come over, giving the dollar in his hand to the coin, and let the little shepherd boy play with the old man.

"Go a few bets with the old man. If you win, my sister will give you candy. If you lose, my grandfather will give you candy."

The little shepherd boy is naturally happy.

Then... the old man lost so much that he almost wiped his tears.

Yang Yuying: “…Puchi!”

The old man's face began to turn green.
