Chapter 24 This is called a one-dimensional equation

"Pheasants, twenty-three; Rabbits, twelve. ”

Just when the others were still counting, Meng Yi shouted out his answer, without any delay.

"Right?"

The First Emperor asked the other ministers, and after a reverse calculation, the answers were correct.

"Back to Your Majesty, what Meng Yi said is the correct solution."

Ying Zheng had a sad face before, and when he learned that Meng Yi said the correct answer, his body shook and he laughed: "Envoys, I don't know if this answer is still satisfied?" ”

Although the Baiyue people didn't want to admit it, but the fact was that they had to admit defeat: "The Qin State is really talented, and we admire it so much, this trip to the north is worth it!" ”

After finishing speaking, the leader did not forget to glance at Meng Yi.

Originally, the Baiyue people gave them an hour, and they were full of confidence, and no one would have calculated the answer in such a short time.

But the result is ......

When Baiyue's envoy came up with the question, before he could be proud, Meng Yi miraculously calculated the answer, and the speed was astonishing.

Everyone looked at Meng Yi with surprised eyes, how could he come up with an answer to such a difficult problem in a moment? Didn't he know the answer in advance?

Obviously, this explanation doesn't work. Baiyue's envoys already wanted to make things difficult for the Qin State, so how could they tell the answer in advance.

Looking around, looking at the projected gazes, Meng Yi shrugged helplessly, in their opinion, this can be regarded as a problem, but in Meng Yi's opinion, it is simply pediatric.

The topic of the envoy is the problem of "chickens and rabbits in the same cage" that primary school students have learned.

This is a primary school Olympiad math problem, which is indeed very difficult for primary school students, but who is Meng Yi? He's a top student.

Pediatrics such as "chickens and rabbits in the same cage" is, in his opinion, simply too pediatric.

At this time, the man led by the Baiyue envoy stepped forward and asked, "Dare to ask Your Excellency, how do you know the real answer?" Is there a convenient way? ”

This is the question that other people want to ask the most, and they definitely won't believe it if there is no convenient way.

Seeing the hot eyes one by one, Meng Yi didn't mind explaining it to them.

So, he picked up a branch and wrote on the ground: "There are 35 pheasants in total, and if there are X pheasants, then the rabbit is (35-X)." ”

"The pheasant rabbit has a total of 94 legs, of which the pheasant has 2 legs and the rabbit has 4 legs, so you can list such an equation, 2X+4*(35-X)=94."

Meng Yi used a branch to walk the dragon and snake on the ground, wrote a detailed solution, and said: "This solution is called the one-dimensional equation method. ”。

Everyone held their breath and stared, all of them stared, indicating that they didn't understand what he was talking about at all, what kind of unary equation method? Why have you never heard of it?

However, in the end, the answer he calculated was accurate, and after his calculations, it was indeed possible to find it in a matter of moments.

Rao was incomprehensible to none of them, but still found it interesting.

Just when others threw themselves on the five bodies that Meng Yi admired, Meng Yi said again: "This is just one of the solutions. ”

It is not easy to solve this problem of "pheasants and rabbits in the same cage", but Meng Yi not only solved it, but also had other solutions.

I'm afraid he's a monster.

The crowd did not believe it.

Meng Yi didn't bother to argue, he did it directly, and wrote two different solutions on the ground, everyone was still confused, but the final result was the same.

The whole process was dumbfounded, and the First Emperor applauded.

Meng Yi gave the empire a long face, not only saved the face of the empire, but also fought back fiercely against the Baiyue envoys.

At this moment, the faces of the Baiyue envoys looked a little heavy, and they could even be said to be ugly.

Their carefully prepared three-round game is more of a puzzle than a game, and each round of puzzle is impossible for ordinary people to solve.

Before coming, they swore that they wanted to make the Qin State lose face and cede the land of the Qin State by the way.

Results......

Juding, horse racing and pheasant rabbit in the same cage, from force to intelligence competition, Baiyue was defeated.

After three rounds of play, all of them were easily solved by one person, and this person turned out to be the first loser in Xianyang - Meng Yi.

Just as the Baiyue envoys were about to leave, Meng Yi stood up again, looked at them, and said with a sly smile: "Huaxia is a country of etiquette, you are guests from afar, how dare we, as the masters, slack off?" ”

Listening to Meng Yi's words, everyone knows that this son has hidden words, which are by no means what he says.

Really......

"Just now the envoy has given us a problem, as the master, we should pay tribute to you, this is a coming-and-going, I don't know if you dare to fight?"

Having said that, if Bai Yue didn't dare to fight, he would really lose face, after all, the Qin State responded to the battle and won three times in a row.

"Okay, I want to ask for advice, the problem of your Qin people, please come on."

Meng Yi chuckled wickedly and said: "My people in Daqin have always been known for their civilized etiquette, and I am afraid that only barbarians can come up with things like horse racing and lifting tripods. ”

While speaking, Meng Yi did not forget to sarcastically ridicule Baiyue as a southern barbarian, which can also be described as killing two birds with one stone.

"I don't know how many things are there today, two of the three or three numbers are left, three of the five or five numbers are left, and two of the seven or seven numbers are left, ask the geometry of things?" Meng Yi said.

What Meng Yi said is the famous problem of "things do not know the number" in "Sun Tzu's Arithmetic", to put it bluntly, it is also an arithmetic problem, which has something in common with the pheasant rabbit in the same cage, but it is completely different.

It is impossible to solve the problem of "things do not know the number" by using the method of pheasant rabbits in the same cage.

Just now, Meng Yi deliberately told them the solution of "pheasants and rabbits in the same cage", which was to deliberately guide them to this idea.

Sure enough, after those Baiyue people heard this question, they actually imitated the equation that Meng Yi had listed on the ground before to solve the answer.

As a result, the more you calculate, the more confused you become.

The confused people, not to mention the people of Baiyue, and even the ministers in the court, were all confused and confused, not knowing what the answer was.

As time passed, no one in the Baiyue envoys gave an answer, and Meng Yi asked, "What?" The envoys and adults can't answer it, this kind of question is a question that even a three-year-old child in Daqin knows. ”

"This ......"

Before, the Baiyue people humiliated the Qin State in this way, and Meng Yi's words were just a tooth for a tooth, humiliating the other party fiercely.

And between the two, the biggest difference is that Meng Yi did it, and they failed.

The first emperor saw that the Baiyue envoy could not answer, and was overjoyed, and said: "The envoy Zhou was in vain, and he was puzzled for a while, but I was very considerate, so I will retreat and rest for a while." ”

said so, but Baiyue people are not stupid, and they can hear the shameful laughter in Yingzheng's words.

In desperation, he had no choice but to leave in disgrace.

After they left, the court was jubilant, and the ministers were excited.

The First Emperor Yingzheng waved his arms and said happily: "Meng Yi, come forward and listen to the order." ”

"Boy, listen to orders."

Meng Yi immediately knelt on the ground and bowed his head and spoke.

"Today, Meng Yi retreats from the Baiyue envoys to have merit, save the reputation of the empire, avoid the shame of land cession, edict, merit and demerits, edict, exempt you from the death penalty, change the sentence to face the wall."

"Boy, thank Your Majesty Longen, may your Majesty live long live, long live, long live."

After the court meeting dispersed, Meng Yi had become innocent, and during the days he was imprisoned, he thought about many things, such as the killing of Tianze, which made him understand a truth, although he came from the future and knew what would happen later.

But life-and-death decisions are still in the hands of others.

If you want to survive in this era of the Great Qin Empire, only by controlling your own destiny can you be proud of the world and be invincible.

Anyway, the Great Qin Empire is like a flash in the pan, and after the death of Qin Shi Huang, it will also be destroyed, so why not become the emperor yourself?

For a moment, even he felt scared at this thought.

Walking out of the front gate of the imperial city, Li Si had been waiting for a long time.

After Meng Yi saw him, he hurriedly bowed and said, "Lord Li's kindness, the kid remembers it in his heart. ”

In the days when he was imprisoned, Li Si, as a court lieutenant, kept playing a plea, begging Ying Zheng to spare Meng Yi's death penalty, and this kindness alone is enough to make people remember it.

"Where did the second son say, if you say that you remember your kindness, it should be me, if it weren't for you, I'm afraid the little girl would have already returned to her hometown." Lees said.

Meng Yi said: "In this way, there will be a tie between you and me, and the matter of Miss Xinyue should not be mentioned again." ”

"Okay, don't mention it." Li Si said with a smile, "However, at today's court meeting, the performance of the second prince surprised me quite a bit. ”

At first, Li Si only recommended Meng Yi to raise the crown, thinking that this kid must have a way, but he didn't expect that in the next two rounds of the game, he would win easily, which was amazing.

"It's just a trick of carving insects, not enough to surprise adults."

"The second prince is really modest, the carving trick you are talking about, but it has made the ministers of the DPRK and China dizzy, I am really curious, who taught these things?"

"If you say it, you may not know it, so don't say it."

Meng Yi waved his hand and was about to leave, he didn't expect that Li Si in history was the kind of person who broke the casserole, so he had to ask for clarification.

But when Meng Yifang took two steps, Li Si behind him said a word, which made Meng Yi like an electric shock, and said: "If I guessed correctly, the first solution to the pheasant rabbit in the same cage is a one-dimensional equation, right?" ”

Meng Yi suddenly stopped and turned back suddenly: "You...... How do you know? ”

"I also know that in addition to bicycles, there are planes, ships and trains in this world."

"Are you......
