Zheng Meng knew that he actually lost the competition today.

Tomorrow, there will be Zheng Ziqing and his younger brother Zheng Jia's seven-year-old son to compete in the six arts, and the news will spread. What other face does he have to discipline Zheng Sheng! So he can't lose, he can't draw, he can only win!

But now: compared to the book, it is said that he is slightly better, but in fact, as soon as the thousand-word essay comes out, he has already lost. Ratio, originally he was supposed to be nine out of ten, he had read nine chapters, and he would not lose to anyone in mathematics. But how did Zheng Sheng do it? He, like Qiu Chudao, had already determined that Zheng Sheng had not read the nine chapters, so how could he solve these problems? Fast and accurate, he felt frustrated when facing Zheng Sheng for the first time. Thinking that he had never looked at this child in the past, what he was worried about had always been Mrs. Wang and the Wang family behind Mrs. Wang.

"Shizi, tell me about it." Zheng Meng had no choice but to accept the offer. This is his last resort to turn defeat into victory, solve this problem, and keep Zheng Sheng in Wancheng! In this way, he is not completely lost.

"It's such a question, well, there are two brothers in a certain place who want to separate their families." When everyone heard this, they showed a strange look.

Zheng Sheng didn't notice everyone's strange expressions, and continued to talk about the question: "Brother asked what brother wanted? The younger brother drew a circle on the ground. Then he said to his brother, 'Put one grain of wheat in the first circle, two in the second circle, four in the third, eight in the fifth, and so on, and so on, and every last circle is twice as many as the previous one, and I only need the grain in the fiftieth circle, and the rest will be my brother.' Ask, how many grains of wheat did my brother want? ”

When everyone heard this, they were a little funny, and everyone thought it was quite simple, so they began to do mental arithmetic, and those who had calculations used calculations. Zheng Meng also sat down again and began to calculate.

Zheng Sheng smiled, simple, yes, very simple, but the number of digits in this topic was beyond their imagination. If he counts in Arabic numerals, he will count it for a while. As for the question of mental arithmetic and arithmetic?

Unless it's a real math genius! Ordinary people can't solve it in a short time.

Qiu Fuzi also sat down, brought a pen, and counted them. I don't know how many circles his old man has counted and can't remember the data?

Quietly, everyone is addicted to calculations.

Zheng Yang stared at the row of Chinese characters in front of him, he faintly felt a headache, it was only the twenty-sixth circle, and then doubled, it was the twenty-seventh circle.

Zheng Miao tore off the paper in his hand, and when he saw Zheng Sheng looking at it curiously, he was silent, he had miscalculated. However, the figures for the first 31 laps should be correct. Zheng Luo counted, millions, millions of grains of wheat, how many stones is that? Just arrived at the thirty-first lap, the fiftieth lap, how many stones?

Half an hour passed, and Zheng Sheng yawned: "Big brother, master, are you still counted?" It's late. ”

Qiu Fuzi scratched his ears and cheeks, and his eyes were red: "Count, you must figure it out!" ”

Zheng Sheng leaned closer, grabbed a piece of paper and looked at it, "Master, you miscalculated, the last digit of the multiple of two must not be singular, and the last digit of your data must be wrong." ”

Qiu Fuzi thought for a while and said angrily: "Boy, the old man has easily reached the forty-fourth circle, don't tell me, I have lost all my efforts!" ”

"Master, it's too late."

Qiu Fuzi was helpless, "Ziqing, what do you say?" ”

Zheng Meng got up silently: "From now on, Nanyang, Shunyang, you come and go freely." Zheng Luo looked at the data in his hand, the thirty-ninth circle, two thousand seven hundred and forty-eight seven thousand nine hundred and ninety-nine thousand nine hundred and forty-four.

When Zheng Sheng returned to Qingzhuju, it was already close to his son. Zheng Cheng and the others hadn't slept yet, and when they saw Zheng Sheng coming back: "Shizi, why is it late to come back?" What the hell is going on in the Academy? ”

This afternoon, Zheng Yun came to Qingzhuju to tell Zheng Cheng that Zheng Sheng had something to do and would come back later. However, everyone waited left and right, and Zheng Sheng didn't come back until the time, it was too late.

After doing several math problems, he was also very tired, so he didn't say anything to Zheng Cheng and them, and waved them to sleep, Zheng Sheng lay on the bed and fell asleep.

Zheng Sheng looked at the balance in front of him, he was very excited! Luckily, it only disappeared for a month, and I didn't lose it permanently. The feeling of being lost and regained made Zheng Sheng very happy. But what to exchange? Zheng Sheng was distressed, he didn't prepare anything this time. Zheng Sheng thought for a while, he decided to purify the few bottles of sesame oil that Dongye brought from the steward, after all, it was not a special oil to eat, and the eggs scrambled with sesame oil used for lighting always made Zheng Sheng feel like something dirty.

Zheng Sheng put the sesame oil on the right tray. Then I thought, I want sesame oil that is purer and suitable for stir-frying, and four bottles of sesame oil appear, and the scales shake and gradually return to balance.

Zheng Sheng glanced at it and found that the four bottles of sesame oil were about half missing. Then, when I was stir-frying with winter leaves, I found that a lot of these oils were mysteriously missing, and it was a trouble to make a fuss!

Zheng Sheng woke up, thinking about the scales that had been lost and regained, and the permission to leave Wancheng. All the unsatisfactory seems to have become beautiful in a short period of time.

He smiled and walked to the kitchen. At this time, the kitchen was already busy, Dongye was busy cooking, and Liu Wei'er started. Zheng Sheng walked in and walked to the location of the bottles of sesame oil, and Liu Wei'er saw Zheng Sheng picking up the oil and looking at it carefully. Liu Wei'er walked over, "Huh? Why is there so much less oil? ”

Winter leaves also walked over: "It can't be a thief, right?" ”

"What do you see in this oil?" Zheng Sheng asked.

"It seems to be much clearer!" Liu Wen'er opened it and asked, "The taste seems to have changed." ”

"Shizi, is this still our sesame oil? It can't be fake, it's really been taken away. "Winter leaves are confused.

"This is what I did with a secret method, and it's not good to eat too much sesame oil. I used the 'secret method' to purify the sesame oil. "The same reason can be continued.

"Shizi, you are so powerful!" Liu Wei'er praised Zheng Sheng.

"Shizi, when did you do it? How did I not know? "Winter leaves have some questions.

"At night." Zheng Sheng said, "After you went to sleep, I made the oil like this. ”

"Is this oil really good?" Fuyuba is still skeptical.

"You'll find out if you try." Zheng Sheng smiled.

At this time, in a small corner of Wancheng, which was a gathering place for displaced people, Liu Neng curled up in the corner of the wall, looking at the surrounding crowd in fear.

Until someone tapped him on the shoulder.

"Brother Wu Zi, you're back!" Liu Neng jumped up excitedly.

"Come with me." Wu Yunlu turned around and left.

Liu Neng hurried to catch up, to be honest, Xiao Liu Neng already regretted not staying with Sniff. Although he hated that son, he could eat well, sleep well, get dressed, and not be beaten!

He asked Brother Wu Zi why he didn't go to find Sniff and them when he entered Wancheng. Brother Wu Zi asked him rhetorically, do you want to be involved with that son again? Don't forget, there, you still have to be a slave! Therefore, Liu Neng once made up his mind not to go to Liu Wen'er.

"Brother Wu Zi, are we going out of the city?" Liu Neng saw the city gate not far away.

Wu Yunlu hummed in response.

"By the way, Brother Wu Zi, there are results in your investigation, right?" Liu Neng remembered that he happened to hear Wu Yunlu say that he came to Wancheng to investigate something. Since you're going out of the city now, things should have been done, right?

"Got it figured out, it's really interesting." Wu Yunlu looked at the county soldiers standing guard at the city gate, and a mocking sneer appeared on the corner of his mouth: "Speaking of which, this matter also has a lot to do with that prince. ”

"Don't you want to be a slave? If we do this well, we will be able to undo his kindness to us. ”
