As soon as Yu Wenshu heard Yang Guang ask this, he knew that it was bad. For this great saint, he knows his inner thoughts very well. Yang Guang said this, no matter whether Nayu Wenming was sure or not, he had to answer. It's fine if you get it right, but if you get it wrong or can't answer it. Even if Yang Guang doesn't say anything at the court meeting today, he will definitely hold a grudge in his heart, and he will definitely find other opportunities to attack in the future.

At this time, he glanced at the helpless Changsun Sheng with hatred. How could his grandson come out of nowhere to answer the problem of the Great Food Messenger? In the end, he was proclaimed to the temple to face the saint? I'm afraid it's mostly the result of this Changsun Sheng's incitement. This guy is too hateful.

Although Yu Wenming didn't know that there was such a complicated secret in this court, he also instinctively felt that if he didn't agree to Yang Guang, I was afraid that the consequences would be very bad. Therefore, he also had to step forward and salute and said: "Xiaomin will obey His Majesty's will and will definitely do his best to win glory for the Great Sui!" ”

After that, he walked up to Mubashaf, patted his chest and said, "Great Emissary, if you have any questions, just mention them!" I Yu Wenming is recruiting! ”

Mubashaf saw that although Yu Wenming was young, he looked like a newborn calf who was not afraid of tigers, and he was also a little impressed. He then laughed and said, "Little doll, if you can really answer my three questions!" In addition to the conditions I promised before, I will also personally give you a horse chopping knife made of fine black steel! It depends on whether you have the real material to learn! ”

Immediately, he paced the hall with his hands behind his back and said, "There is a wise man in our Great Eclipse who will be put to death by the king for making a mistake. And the king, who loved his talents, wanted to save him from death, but feared that he was only famous and had no real wisdom, so he wanted to test him...... Before the execution, the king summoned two guards, each with a glass of wine in his hand, both of which had the same appearance, and even the wine was exactly the same color and taste, and it was impossible to distinguish the difference. ”

Then the king said to the wise man, 'I will give you one last chance to live.' The two guards held two glasses of wine, one poisoned and the other good. And the two guards, one who only told the truth and the other who only told lies, knew which glass of wine was poisonous and which was good wine. ”

"I'm giving you a chance to question one of them. After asking, you have to decide right away: which wine is poisonous and which is good? If you judge correctly, I will grant you good wine to live. If you are wrong, then you are not a wise man at all, and you only deserve to die by drinking poisoned wine! ”

Speaking of this, Mubashaf said with a smile: "Yu Wenming, you have an idea for that wise man, how should he ask questions in order to judge which glass of wine is poisonous wine and which glass of wine is fine wine?" ”

When the ministers heard this, they all looked at each other. Secretly thinking that the two glasses of wine are exactly the same appearance and color, it is impossible to tell which glass is a fine wine and which is a poisonous wine glass from the naked eye. But although these two guards knew the truth, one only told the truth, and the other only told lies...... If you ask the right guards who tell the truth, it's okay. But if you ask the wrong person, it's miserable...... It's just that before you know the true identity of the other party, how can you judge whether the guard's answer is credible! ”

After Yu Wenshu and Yu Wenhua heard about it, he was even more anxious, secretly thinking that this topic was completely gambling. The opportunity is half to half, how can you be sure of asking the truth?

Seeing this, Yang Xuan was smiling with a haze on his face, secretly gloating, thinking that even he couldn't think of how to ask to get the correct answer to this question for the time being. This Yu Wenming is just a twelve-year-old child, what kind of insight and wisdom can he have?

However, what he didn't expect was that after only a cup of tea, Yu Wenming replied loudly: "I have already figured out the answer to this question." The wise man only needs to ask one of the guards: 'If I ask your companion, is the cup in his hand filled with good wine or poisoned wine?' How would he answer? Then you can tell what happened to the two glasses of wine! ”

As soon as Yu Wenming's words came out, the hall was shocked, and many ministers showed disbelief. Even Yang Guang was taken aback, and he hurriedly asked, "Yu Wenming, why did you say this?" Why do you need to ask so much that you can know the truth about two glasses of wine? ”

Yu Wenming smiled slightly, this topic he had heard from a colleague in his previous life, it was a brain teaser question, so of course he knew the answer.

He replied confidently: "For the guard can only answer in two ways: in the first case, the guard says that his companion will say that he has poisoned wine in his hand." In this case, the poisoned wine is actually in the hands of the guards who were questioned by the wise man. In the second case, the guard said, his companion would say that he was holding a fine wine. And in this state of answer, the wine is actually in the hands of the guards who are being questioned by the wise man. ”

"Yu Wenming, what is the reason for your inference for saying this?" Yang Guang asked puzzled. He didn't notice that Mubashaf's face had changed.

"O Holiness: If the wise man is questioned by a guard who tells the truth, then his companion is a liar. Thus, when he recounts the possible answers of the lying guards around him, he describes the falsehood...... And if the wise man is questioned by a guard who tells lies, then his companion is the one who tells the truth. Therefore, when he recounts the possible answers of the truth-telling guards around him, he reverses the answers of the other party. So the situation depicted is naturally fake......" Yu Wenming said this, pausing slightly, allowing Yang Guang and other important ministers in the main hall to have a time to think.

Then, he said, "From this, it can be concluded that whatever the guards' answer is, it is exactly the opposite of the real situation. Therefore, the wise man only needs to switch the position of the fine wine and the poisoned wine according to the answer of the guard, and this is the real situation. In this way, he can save his own life! ”

Above the main hall, it was so quiet that you could hear the sound of a needle falling on the ground. The monarchs and ministers of the Sui Dynasty in the court were all thinking about Yu Wenming's words. A moment later, Pei Ju and Changsun Sheng were the first to figure this out and smiled.

And not long after, Yang Guang, Yu Wenshu, Yang Xuangan and others also figured out the joints. It's just that Yang Xuangan's face is a little unpleasant, he didn't expect such a difficult question to be solved so quickly by Yu Wenming.

"Mubashaf, how's it going? Are you still satisfied with this answer? Changsun Sheng asked with a smile.

Na Mubashaf had no choice but to step forward and say: "This first question is relatively simple, and with the ingenuity of the little boy Yuwen, it is not difficult to solve. But there are two more questions! ”

"Good! Just name the title of the second question! Yang Guang's confidence also increased greatly at this time, and his eyes when he looked at Yu Wenming also had a hint of appreciation.

Mubashaf's face was a little pale, and after he cleared his throat, Fang continued: "Then I will talk about the title of the second question: there is a merchant in my country, and he wants to hire a man to be the treasurer and help him in business. However, he demanded that the treasurer must be a very smart man. After the news broke, his nephews and apprentices came to apply. The merchant decided to choose the wiser of the two to be the treasurer. After several days of contemplation, he finally came up with a way to put it to the test. ”

After a pause, Mubashaf continued: "The merchant took his nephew and apprentice to a basement where he couldn't reach his fingers, and then he nodded to the oil lamp. The two looked around and found that in this basement, there was only a table and a chest, on which were placed five hats, two red and three black. ”

"Then the merchant said, 'Wait a while, and I will blow out the lamp and mess with the position of the hat.' Then each of the three of us took a hat and put it on our heads. When I light the oil lamp again, you will tell as soon as possible what color the hat you are wearing on your head. Whoever says it first and answers it correctly wins. He's going to be my hired buddy! So the merchant blew out the lamp. Then each of the three men touched a hat and put it on their heads, and the merchant locked the other two hats in a box to keep them from seeing. ”

A moment later, when the merchant lit the lamp again, both his nephew and his apprentice saw that the merchant was wearing a red hat and the other was wearing a black hat. After being stunned for a long time, his nephew took the lead and said, 'I have a black hat on my head. Then he defeated the apprentice, won the assessment, and became the treasurer. How did the merchant's nephew tell that he was wearing a black hat? Mubashaf said in one breath.

When the ministers heard this, they all frowned. I wonder how I can tell this?

Of the five hats, two are red and three are black. Whether it is a nephew or an apprentice, they can only see one red and one black, which means that the hat on their head may be black or red, and the probability is only half.

If they were nephews, I'm afraid they would have to guess by luck.

But Mubashaf said that the nephew had a well-founded judgment that he had a black hat on his head. On what basis can this be judged?

Su Wei, Pei Ju, Yu Wenshu and Yu Wenhua and others glanced at each other, and they all saw a confused look in each other's eyes.

Just when everyone was in deep thought, Yu Wenming breathed a sigh of relief, this question was similar to the one he saw in CCTV's Happy 100 column in his previous life. He should still be able to answer.

So, he said leisurely: "I think that nephew must have inferred like this: if he is also wearing a red hat." Then, the apprentice can immediately guess that he is wearing a black hat. ”

"Because there are only two red hats, and if the merchant and his nephew both wear red hats, the apprentice will not be able to judge it. But now the apprentice has not spoken for a long time, which shows that he is also hesitating. The nephew could tell from this that he was not wearing a red hat, but a black hat. "Yu Wenming is the right color road.

When the ministers in the main hall heard this, they all showed thoughtful eyes.
