Of course, whether he is a bandit or a mountain chief, this has nothing to do with Yang Yuying, but this old man 'covets' Yang Yuqing's 'Feng Shui Treasure', and he has to make a bet with her, whoever wins will occupy this place to fish.

Yang Yuying is really past the age of fighting for this, of course, she took the initiative to stand up and give way, but people are unhappy and unhappy, it seems that it is not a serious thing, and the old people can't enjoy it.

The so-called old and young, the older the younger, the younger, about that.

That's it, it's idle anyway, she laughed with the old man and coughed for a while, smiled and made a bet, and let the old man bet what he wanted.

If you talk about gambling on something else, Yang Yuying may not win, when she was in Dashun, she was entangled in the fly camp dog in the inner house all day long, and she never even went to a serious academy, and later the imperial court ran a university, she just looked at it and sighed, until she heard that Zhao Jin was admitted to medical school.

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

Oriental Danqiu West Taihua, towards the North Sea twilight, the end is at ease.

However, as an intelligent being, you must also learn some skills on your own, after all, it is easy to learn.

At this time, the old man had to bet with her to solve the problem, and the solution was still a math problem, and he would solve each other's problems, and whoever couldn't solve it first would lose.

Yang Yuying: "......"

The old man sat on his knees, upright, smiling with his beard, with a smug face: "Don't say grandpa, I bullied you as a junior, just make a ...... that my nine-year-old grandson would do"

Then, he asked: There are people in the stable who also have horses, adding up to 22 heads and 72 legs, and ask how many people and how many horses are in the stable?

This kind of water blue star has been in the same cage since ancient times, if Yang Yuying doesn't know how to count, the marshal can jump out of the coffin in anger...... Destroy all those who saw this scene, so that she would not have the face to see people.

So, after the old man finished talking about the topic, before she could say the triumphant cruel words behind her, she smiled while stuffing fish into the fish basket: "14 horses, 8 people." ”

Old man: "......"

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

However, this old man is indeed a solid scholar, has a considerable study of Western studies, and the methods of solving mathematical problems are also very advanced, both spirituality and patience, no matter how slow he is to do the problems, he is serious and meticulous.

At a time when there is an old account office and Arabic numerals are not very useful, the old man in front of him is definitely a fashionable gentleman.

For most of the day, the old man became more and more troubled, his eyes lit up, and she glanced at it when she was gnawing on the fish, almost thinking that she had recruited a wolf.

Two days later, the old man finally got stuck on a question.

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

This kind of tricky question is done well, know the routine, any citizen with a normal IQ and an understanding of the school in the Middle Ages, mental arithmetic can simply produce results, the problem is that the old man of the ancient times must not have received the cramming education and question sea tactics of the Middle Ages, let alone seen countless brain teasers, math fun quizzes.

She didn't pay attention to it at first, but when she came back to her senses, she found that the old man was squatting on the ground, gesturing with a branch and engrossed on the ground, sweat rolling down, and wetting a large piece of the ground in front of her.

Yang Yuying's eyes didn't move, and she was also shocked in her heart, for fear that he would be too energetic and make trouble again.

In his fifties, he was in the interstellar era, he was a young man in his prime, but he was already dying and old, and he was full of diseases, Yang Yuying saw that his old man's lips were black and his nails were purple, not like he was very healthy.

"Old man, I'm a poor donkey, random questions, this round counts me as losing, the place lets you, the stone lets you, or I will burn two more fish for you to suppress the shock, you hurry up and come fishing, how about it?"

The old man didn't squint, and he didn't even glance at her: "The rules are set by me, and the questions you came up with are not broken by the rules, and there is no problem." ”

The breeze blows, as if it has a stubborn smell.

Yang Yuying persuaded several times, almost the real Qian donkey skills were poor, desperately rushed to follow the old man's few pieces of wood to make eyes, but the eyes were all thrown to the blind man, and his mind changed, and he simply didn't care whether the old man wanted to know or not, grabbed the other party's pen and paper, brushed and wrote the result - 81×500000000+1=40500000001.

"It's very simple, the first number and the penultimate second number, the second number and the penultimate third number, and so on, divided into 500 million pairs, the sum of each pair is 81, and the sum of the numbers of the last 10000000000 is 1, that is, 500 million 81 plus 1."

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

"It's that simple? How simple is it? ”

The old man muttered to himself, happy for a while, annoyed for a while, as if he was full of emotion, and instantly full of energy, turned his head and his eyes lit up: "What else, show me again?" You little girl, although the questions are not difficult, they are really interesting and interesting! ”

Yang Yuying: "......"

Do you want to stop giving him an inlet pipe, a problem with the water outlet? See if he's tired or not!

The marshal said that in the Middle Ages, schoolchildren and parents, all because of terrible math problems, there were countless bald people, if everyone had this old man's enthusiasm for mathematics, then not everyone would become mathematicians?

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

Does she have no hobby for math at all? Isn't the game fun, or is the food not tasty? Practicing swords is also better than playing math problems!

Being pestered by an old man all the time to ask new questions, who knows what it feels like.

Yang Yuying also had a headache when she was asked, so she didn't struggle at all, she just lay down and let him toss, but she couldn't take advantage of it at all, she was all at her own loss, which was not in line with her principles.

"Old man, it's not good to give you interesting questions, if you really want to know, then you also want to exchange the knowledge I am interested in?"

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

"Okay, then take a gamble!"

Yang Yuying, "It doesn't have to be too complicated, No, let's throw a coin." ”

Take turns throwing, the first to throw out the negative wins, the loser loses to the other party a lone book, whether it is piano, chess, calligraphy and painting, or medical divination and astrology, as long as the winner is interested.

After playing seven rounds in a row, the old man lost everything, and he wrote the notes of debt so that his hands trembled, and he was so angry that he couldn't wait to cry: "Cheating, how did you cheat in a little girl's film?" ”

Yang Yuying was also surprised, so she was not annoyed, but smiled: "Old man, it's your luck that makes people too indescribable." ”

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

"Bet a few games 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.

And then...... Then the old man lost so much that he scared people so much that he almost didn't wipe his tears.

Yang Yuying: "...... Poof! ”

The old man's face faintly began to turn green.

Yang Yuying: "Your old man is unlucky, who can blame him?" ”
