"If you can't catch it, you can't catch it, why are you crying," Yu Shu forced people into a corner, still showing no mercy, and mocked:

"With this ability, the number is not accurate, you can only cry and cry your nose, and learn from others to fight, I don't know what to do."

I think that in order to learn actuarial science, eight crab legs were counted early and late, counting and counting, for three years, it was easy to count five hundred in one breath, not that she looked down on people, and she was interested in the long and short, if this little girl surnamed Hou had worked hard in arithmetic on weekdays, it would not be enough to count even a hundred crabs.

Hou Luting was embarrassed by Yu Shu's few words, her face was full of shame, she couldn't afford to be stubborn, she hid her face and turned away, she didn't dare to look at the faces of several senior brothers, and she endured it so that she didn't rush out of the door.

Jin Zuoying himself only lost a game, it's hard to say that this little junior sister is not, but he is not in the mood to comfort. Pan Ming sighed lightly, stepped forward and patted her on the back, stared at Yu Shu deeply, and said in a deep voice: "My junior sister is not as good as a female operator, as I said before, it is still a draw." ”

Yu Shu nodded, seeing that the other side couldn't come up with the question for a while, so he sat on the chair and waited.

After waiting for another cup of tea, Hou Luting finally calmed down, turned around with red eyes, and said to Yu Shu:

"Female operator, it's my turn."

Yu Shu lifted his eyelids, but he didn't get up, "You say." ”

She respects respectable people and repays her affection, which is her temper and arrogance.

She didn't feel complacent about winning over these ancients with her scholarship hundreds of years ahead, but she had a clear conscience, and what she could rely on today was what she had exchanged for her sweat bit by bit.

Hou Yuting glanced sideways at Jin Zuoying, who nodded at her, bit her lip, and said in a nasal voice:

"Yes, there are twenty soldiers lined up, and only four soldiers can stand in each row, if you want to line up, how many lines can you line up at most?"

Her voice fell. Yu Shu's hand shook and almost dropped the teacup on the ground, but he couldn't help but write his surprise on his face, and lowered his head to memorize the question. But in my heart, I was surprised and delighted—

The twenty soldiers' questions were clearly the same as the very famous "Twenty Trees" puzzle she had seen in modern times, except that the trees had been turned into soldiers.

It's not a math problem, it's not a math problem, it's a drawing problem!

A problem that has been sought by famous mathematicians throughout history to break through the permutation of numbers, but its final answer. But it's a question mark.

Such the same topic should not have been raised in this dynasty, but Yu Shu ran into it, is it just a coincidence?

Yu Shu's eyes flickered, and she turned to tell Fluttershy to go to her study and get a wooden ruler and her charcoal.

With the tools in hand, she first drew a few random strokes on the paper, looking for the complex and vague map in her memory, and at the same time. For the old operator who has never met, a strong curiosity arises.

Of course, she would not be stupid enough to think that this real "problem" was really thought up by these few people in front of her, which could make them so confident. It must have been from Han Wenguang.

***

Yu Shu sat on the chair, and after half an hour, she had a stack of used manuscript paper piled up at hand, but she was still drawing.

Some of the drinkers present couldn't sit still, so they ran to the hut and hurried back, for fear of missing the scene where she solved the problem.

In the past half hour, the other group of people was obviously much more relaxed, standing and sitting. Quietly waiting for Yu Shu to solve the problem, it is rare that no one urged out loud, this is the respect that Yu Shu used to exchange for actions before, it can be seen that whether it is friend or foe, strength is the best countermeasure to gag people's mouths.

Xin Liu's legs were sore, and they had already found a stool to sit on. In the light and in the dark, only Xue Rui was with him, and he stood there as long as Yu Shu sat there.

At this time, the guards around Liu Tan approached Xue Rui quietly and passed a note to him, Xue Rui opened it, but saw a row of small characters written on it:

A draw is sufficient, and if I want to intervene, I will not be able to make it happen.

Xue Ruixin said that Liu Tan still couldn't help it, he knew why he was so anxious, in fact, Han Wenguang had an only son, and he was married to the young lady of the Yin family, the first prestigious family under the name of the emperor in the capital, that is, an aunt of Liu Hao, the king of Ning, how could he sit back and watch Han Wenguang succeed!

A draw is good, but also

Xue Rui turned his head sideways, his eyes looked over the colorful bouquet that opened, staring at Yu Shu's back on the desk, but it was difficult to choose in his heart.

After a while, he pinched Liu Tan's note in the palm of his hand, and Zhengse instructed the guard:

"If you go back, just say that I told you, if you can't win, I will bear all the consequences."

Retreating from the guards, Xue Rui put the crushed note into his sleeve, not being seen by Pei Jing and He Fangzhi, who were sitting not far away, his eyes fell back on Yu Shu, and a wisp of helplessness leaked from the corners of his eyes, habit is really a terrible word, he didn't know if his decision was correct, but a voice in his heart had already told him:

Help her.

***

Soon, the sun set, and an afternoon passed in such a hurry, and the sunlight shining on the table fell like a curtain, until the last corner of the sunset left the corner of the table, Yu Shu finally put down the pen, let out a long breath, and wiped the sweat on his forehead.

"Phew."

Outside the forgetting building, I don't know when many onlookers gathered, whispering everywhere, guessing whether she had solved it.

Pan Ming looked at Yu Shu and sighed, he was a little nervous, this time he didn't wait for Jin Zuoying to ask, he stepped forward and said:

"Is there a solution for female operators?"

Yu Shu put the last piece of drawing paper on the table, raised his eyes and said, "I ask you a question, I hope you will answer me truthfully." ”

Pan Ming nodded, and couldn't wait to know the result.

"This third question, has your mentor, Han Wenguang's seniors, ever solved it?"

Pan Ming felt that there was nothing to hide about this, these three questions, deceived the layman and said that they came up with it, he believed that Yu Shu had already guessed that it was from the teacher's handwriting, so he ignored Jin Zuoying's eyes and confessed:

"The tutor has solved."

Yu Shu smiled reassuringly, uncovered the paper on the table, held it up in front of him, and let him see the graphics on it clearly, and his voice was bright:

"As you can see, I have discharged twenty lines, I don't know how many lines can be discharged at most, Mr. Han Wenguang."

Pan Ming and Jin Zuoying clearly saw the picture outlined by Yu Shu with charcoal and a ruler, and they were dumbfounded, and when they heard her question, no one answered for a while, and there was only horror in their eyes-

Twenty lines!

"Twenty lines?!" Someone exclaimed on the spot, in the past half an hour, many people have been curious to follow the arrangement, most of them have nothing to do if they list four or five lines, how can they not be shocked that she can list twenty lines!

Some people didn't believe it, so they left the table and stepped forward to watch, counting the figures outlined with fine lines in Yu Shu's hand, counting them one by one, and then, they were all dumbfounded.

Yu Shu didn't raise his hand for too long, and when everyone who approached saw it clearly, he put it down, closed his sore eyes, and asked again:

"Pan Dasuan, Jin Dasuan, dare to ask how many lines can Lingshi solve?"

Pan Ming was silent, staring at the drawing that Yu Shu put on the table, Jin Zuoying was also speechless, how did he answer this question-

If it is said that his master also solved twenty points, wouldn't it mean that she won the game because she was the correct solution?

But if she said that she had solved one line less, if she made it difficult for them to demonstrate on the spot how Master had solved the twenty-one line, how could they lie?

What frightened them the most was that the master had solved only eighteen lines!

Yu Shu looked at their submissive expressions coldly, forcing people to this point, and then she stood up lazily, moved her shoulders, and said:

"Say, what's so unspeakable about this, is it possible that Old Han doesn't have as much as my junior to solve?"

As soon as these words came out, there was silence inside and outside the building, and a pair of eyes of doubt or disbelief swept towards the five senior brothers and sisters.

Jin Zuoying saw that the gaffe was getting more and more beyond what they wanted, so he hardened his head and said ruthlessly: "Don't talk nonsense, how can the family teacher not solve as much as you, and his old man has solved it——"

"Hahaha!"

At this juncture, a series of hoarse laughter came from outside the door, which interrupted Jin Zuoying's answer.

Yu Shu's eyelids jumped, his eyes jumped to the door, and he saw that the crowd blocking the door was separated, and the two guards opened a road, and out of it stepped out a goosebump-haired old man, who was low and thin, wearing a big green cardigan, with a pair of long eyebrows hanging down at the corners of his eyes, revealing a pair of narrow eyes.

"Master!"

"Master!"

Pan Ming and the others shouted in unison, and each bowed down to worship, revealing the identity of the person who came, it was the famous Han Lao operator.

Yu Shu met the old man's eyes, staring at the invisible coercion, not bowing his head, not flinching, not saluting, and not greeting.

Han Wenguang waved his hand to let several lovers get up, and walked towards Yu Shu with his robes, looking at them while saying in a hoarse voice:

"You are the female operator who came out this year, Yiyang Yushu?"

"It's me."

Han Wenguang looked her up and down, suddenly squinted his eyes, and said solemnly: "Do you know that because of you, the old man has one less operator apprentice under his name?" ”

"It's only to blame the apprentice for not being good at learning, what does it have to do with me." Yu Shu spoke coldly, and on the spot, Pan Ming's popular muscles burst out.

Who knew that the corners of Han Wenguang's mouth raised, and he actually smiled, nodded and said, "You kid, very good, very good." ”

If in normal times, someone was praised by Han Wenguang himself, and he smiled unhappily and crooked his mouth, but Yu Shu only had a grudge against this old man, and he had no good impression at all, so he felt that he was acting in a coy manner at the moment, so he didn't appreciate it, and asked directly:

"Just now, I asked Gao to give me a question, I heard that Mr. Han has also solved it, I don't know how many you have solved."

Han Wenguang waved his hand and said modestly: "Alas, the old man is old, and his brain is not as good as that of young people, so he only solved eighteen lines, see laughter, see laughter." ”

Yu Shu raised her eyebrows, and said in her heart that this old man knew each other, and if he dared to fight with herself, she would want him to be discredited today-

No one knew that there was another picture on the table she had covered, and there were clearly twenty-three lines on it! (To be continued.) If you like this work, you are welcome to vote for recommendation and monthly passes, and your support is my biggest motivation. )
