The ancient life of a master craftsman

Li Enbai looked at him strangely, "Are you sure?"

"Of course!" Sun Mingzhi thought to himself, only by defeating you in the field you are good at can prove that I am better than you.

"Oh." Li Enbai turned his head to look at Shi Wenbai, "Do you want to compare Mr. Shi?"

Shi Wenbai hesitated a little, looked at the students present, "This..."

"If there is no competition, Sun Gongzi will compete with me alone. I will return home after the teacher appreciation banquet." Li Enbai wanted to solve the small troubles together, otherwise someone would always miss him and trip him up secretly.

"Bi, Mr. Li, Wen Bo also wants to ask for advice." Shi Wenbo immediately expressed his intentions, he could hear Li Enbai's intention to not accept the challenge this time, afraid of missing the opportunity.

"Okay, that's fairer, let's play one game per person, win two out of three games, is it feasible?"

Li Enbai knew that if he beat them with something they were not good at at all, the two of them would not be convinced, so they simply said that each player had one game, and compared what they were good at.

"I will make the questions first, and everyone can choose the one they are good at." Li Enbai saw that the two of them had no objections, so he continued.

Shi Wenbai and Sun Mingzhi had no disagreement at all, it was the most fair, Sun Mingzhi thought, if he could win, Shi Wenbai would also be suppressed by him.

"no problem."

"Li Sanyuan, please come up with a question." Sun Mingzhi was eager to try.

"Well, let's compare..." Li Enbai paused intentionally, turned his gaze around, and stopped at the gate for a second, "Let's do the math, it must be difficult for such a simple thing to be difficult. Talented."

"What?!" Sun Mingzhi was surprised, "What are you talking about?"

"Count?" Shi Wenbo couldn't help asking back.

"Naturally, isn't it better than me? It's okay to count me." Li Enbai had a gentle face, the corners of his mouth were turned up, and the arc of his smile was just right.

The serious appearance made Sun Mingzhi unable to say anything, so he could only grit his teeth and say, "Then how do you want to take the test?"

"I'll give you a question and you two should answer it. You two will each ask a question and I'll answer it." Li Enbai had already thought about the question.

Sun Mingzhi and Shi Wenbai looked at each other, then turned their heads and agreed, "Okay, Mr. Li, please come up with a question."

"Well, let me think about it, why don't I give you a simple one first?" Li Enbai was about to sacrifice the chicken and rabbit in the same cage.

Sun Mingzhi felt that he was looking down on them, and immediately said, "Mr. Li doesn't need to take care of us, just follow your level."

"Linfeng, Wen Bo also wants to experience a difficult problem." Shi Wenbai's unwillingness to admit defeat was also provoked.

Li Enbai originally wanted to change a difficult problem according to their ideas, such as an indefinite integral or a Bayesian formula, but since calculations are not taken seriously now, no one knows these formulas, if it is really out, it is purely bullying up.

So according to the original plan, the problem of chickens and rabbits in the same cage was raised, "My topic is this. A total of 78 chickens and rabbits are raised in one cage, with a total of 200 legs. Excuse me, how many chickens are there? How many rabbits are there?" How many are there?"

Sun Mingzhi asked first, "Is this a difficult problem or an easy one?"

Seeing his posture of breaking the casserole and asking the end, Li Enbai didn't want to make extra troubles, "It's difficult."

Seeing his understatement, Shi Wenbai didn't really want to write about difficult problems, "Can Linfeng tell you what simple problems are like?"

"Yes, it's very simple. From 1 to 100, what is the total? The time to answer the question is half a stick of incense (2 minutes), and if you exceed the time, you will fail." Li Enbai said one casually.

When I heard him posing the question just now, there were still people around laughing, but they were a little silent when they heard the time limit. Addition is not difficult, and it is not difficult to add from one to one hundred. The difficult thing is to count in half a stick of incense. over.

Shi Wenbai asked someone to light incense, "Linfeng, let me try this simple one first, and then calculate the difficult one, is that okay?"

"Of course." Li Enbai looked at the censer and incense that would be delivered soon, his eyes flashed, and he raised his voice, "Anyone who wants to try can count after the incense is lit."

"Li Xiucai, I'm lighting the incense." The servant lit the incense, then stepped aside, obviously helping to calculate the time.

Li Enbai sat back in his original position, "The answer will be announced after half a stick of incense."

His leisurely and leisurely appearance really made people angry. The students present all tried their best to calm down and calculate. It was just an addition, and it was just a faster calculation.

Because there is no pen and paper, they can only calculate in their heads. Many people lowered their heads and concentrated on calculating. Sun Mingzhi was one of them, and his forehead was covered with sweat.

The time for half a stick of incense is too short, the young servant dutifully extinguished the incense at the half stick, "The half stick of incense is here!"

Li Enbai looked up at Shi Wenbai who was frowning, "Did Mr. Shi figure it out?"

"I'm ashamed, I only counted to 72, the answer is 2628, there's no time to add up the rest." Shi Wenbai generously admitted failure.

Sun Mingzhi also raised his head when the boy said the time was up, but Li Enbai asked Shi Wenbai first, and he couldn't interrupt. Now that Shi Wenbai failed, he immediately said, "The answer is 5050, am I right?"

Li Enbai smiled, "Mr. Sun is right, the answer is 5050."

Before he could show his complacent expression, Li Enbai said again, "Then Mr. Sun can start to calculate the problem of chicken and rabbit in the same cage." He gestured for your invitation.

His words froze Sun Mingzhi's smiling face, and then he remembered that what he worked so hard to calculate was just a simple problem.

"Hmph, I see." Then, in order to save face, he asked, "I wonder if there is a time limit for this chicken and rabbit in the same cage problem?"

Li Enbai thought for a while, "That's not true, but I'm probably a cup of tea." It was still around ten years old.

Sun Mingzhi heard it, and immediately began to calculate in his heart, he must calculate it within a cup of tea (10 minutes)!

Shi Wenbai had calculated the simple addition problem, and already knew that he was no match for Li Enbai in terms of calculations, so he didn't count, and thought about it again when he got home.

"Linfeng, does this Chicken and Rabbit in a Cage come from "Sun Tzu's Suan Jing"?" Shi Wenbai and Li Enbai discussed the source of the title.

"That's right, the original question is, 'Today there are pheasant rabbits in the same cage, with 35 heads on the top and 94 feet on the bottom, what is the geometry of the pheasant rabbits?', I changed the numbers in it, but the algorithm has not changed. The topics are pretty common." Li Enbai talked softly with him, not wanting to disturb Sun Mingzhi's calculations.

"Oh? Apart from this chicken and rabbit in the same cage, are there other similar topics?"

"Yes, for example, there are 27 boxes of brushes with a total of 300 brushes, a box of 10 Langhao brushes, and a box of 12 Yanghao brushes. Please ask how many of each." Li Enbai gave an example casually.

After hearing this, Shi Wenbai was thoughtful, as if he understood something, but he didn't grasp it.

Time passed bit by bit, and it was time for the banquet soon, and the time for a cup of tea had already passed, and Sun Mingzhi hadn't figured it out yet, and was scratching his head.

Mathematics is something that people who know it really don’t find it difficult. Those who don’t know it will feel a little headache when they hear numbers.

The simple addition problem just now has exhausted many students who only pay attention to poetry and poetry, and now the problem of chicken and rabbit in the same cage is even more confusing for them.

So many people don't count for the time being. Tonight's occasion is not for counting. Making contacts is the most important thing.

But the top three in this hospital examination have been sitting together, so they can't ignore it.

Seeing that the time was approaching, Li Enbai patted Sun Mingzhi on the shoulder, "Mr. Sun, go back and calculate slowly. I will tell you the answer in a while. Let's sit first."

Sun Mingzhi pursed his lips, suppressed his resignation, and followed Li Enbai and Shi Wenbai to the main table.

The three of them are ranked next to each other, and their seats are also next to each other, but Li Enbai's position is like a moon surrounded by stars, and the two of them are stars next to the moon.

Behind them are the top [-] of this imperial examination, that is, all the grannies, and the opposite of their top [-] is the remaining [-].

Li Enbai was alone at the table, as were Shi Wenbai and Sun Mingzhi, but there were two fewer dishes on the table than him, and the seats were a little behind him.

No.4 to No.10 are at the same table, right behind Shi Wenbai, and Sun Mingzhi has eleven to twenty behind, and then 21 to forty, at a long table.

Their side formed a triangular seating arrangement. Opposite them, there were 60 people on the opposite side, 41 to [-] people were on a long table, and the [-] people behind were recorded on another long table.

Li Enbai imagined this scene in his mind, such an asymmetrical and irregular arrangement was quite uncomfortable.

Before the banquet was about to start, the servants came in with tables and chairs and placed them on Li Enbai's side. After they were put away, they became a rectangle with two symmetrical sides.

As soon as the food was set on the table, I heard the servant outside the door shouting, "Master Zhifu is here!"

"Hahaha." The magistrate's laughter came first, and then a rich middle-aged man stepped in. He walked in with his hands behind his back, and there were several people behind him, one of whom was the master secretary that Li Enbai had seen.

"I have met the magistrate!" No need to be taught, a hundred scholars met with the magistrate together.

"There is no need to be too polite. Today is a celebration banquet for all the scholars. If you can be on the list, you will be the pillars of the country in the future. Everyone, sit down, hahaha." The prefect said very happily.

After everyone sat down, the officials who followed the prefect also sat down. The prefect sat at the head and asked, "Who is Li Enbai?"

Li Enbai stood up and cupped his hands, "Student Li Enbai, I have met the magistrate."

The magistrate took a look at him, "As expected of the little Sanyuan who meets once in ten years, he really looks good, hahaha, reward."

"Thank you, sir." Li Enbai was neither humble nor overbearing, and his etiquette was very standard, no one could tell that he was from a farming family.

"You don't need to be too polite, Li Sanyuan, today is a day of great joy, why don't you compose a poem, how about it?"

Li Enbai didn't even blink his eyes. He smiled and said, "My lord, the students are not good at poetry and poetry. How about Shi Xiucai or Sun Xiucai come here? Don't spoil everyone's interest."

The magistrate smiled and said, "Li Sanyuan, don't be modest, you should start with such a good day today."
