Originally, on the first day of the Lunar New Year, envoys from various countries such as Goguryeo, Silla, Turkic, Turpan, and Wa would meet the Emperor of the Tang Dynasty. As in the past, after Taizong presided over the sacrifice, he received the envoys in the Taiji Hall. Hundreds of officials kowtowed, and the envoys went to the temple.

Taizong sat on the dragon seat, not angry but mighty, and said: "When it comes to New Year's Day, recalling all the things of the past year, all the wind and rain are smooth, and the country and the people are safe, so I am very pleased!" After a slight pause, he continued: "This time the envoys of all states came to congratulate each other, which is really a blessing for all the people, a blessing for the court, and a blessing for me......

Taizong's mouth was like a river, and he made witty words, and he stopped after talking for half a moment.

The Turkic envoy Ashina Linyun stepped forward and saluted: "The envoy of the Turkic country, Ashina Linyun, has seen His Majesty the Tang Dynasty, and wishes the people of the Tang Dynasty a prosperous country, and also wishes you and us to live in peace!" After discussing with the envoys of other countries, the foreign minister wants to try a competition with the famous people of the Tang Dynasty, and I hope that His Majesty will approve it! ”

When Taizong heard this, he said coldly in his heart: Hmph, the country of projectiles also wants to compete with the dignified Tang Dynasty, which is really beyond his strength! smiled slightly, and blurted out: "Accurate!" Eldest grandson Aiqing, you can arrange it! ”

A hint of a wicked smile flashed at the corner of Ashina Lin Yun's mouth, and he said: "Your Majesty of the Tang Dynasty, my Turkic Jieli Khan has prepared a thousand good sweat and blood horses, if someone in your country can compare with the foreign ministers, then the thousand good horses will be given to Your Majesty as a New Year's Day gift!" ”

When Taizong heard about the thousands of sweaty and bloody BMWs, he was unconsciously moved and said, "Oh? Tell me about it! ”

Ashina Lin Yun held up the almost transparent, reddish glass cup in his hand and said: "The first question is to pour this cup full of water, and turn it upside down so that the mouth of the cup is facing down, and the water cannot flow out!" ”

A cadre of ministers, including Taizong, only then did he understand that Ashina Lin Yun had been holding a glass cup, what the hell was he doing!

For a long time, no one said anything to answer the question, Taizong was a little displeased, and coughed lightly. The eldest grandson Wuji suddenly understood, stepped forward and bowed: "Your Majesty, since Ashina's envoy has this Yaxing, it is better to wait for the court meeting to disperse, arrange a good life, and then have a competition!" ”

Ashina Lin Yun heard this, revealing a trace of disdain. Although Taizong saw it clearly, he couldn't help the incompetence of the ministers, and said: "What the eldest grandson Aiqing said is very true, this matter will be handed over to you, and it must be arranged properly!" When he came, he showed a smile and said, "By the way, this little matter, it is better to invite Qin Xuan to come, I expect that this son will definitely not disappoint me!" ”

This is the scene where the Qin Mansion receives the order.

At the end of the day, Chongwen Temple. Taizong is still high and sits in the middle. The eldest grandson Wuji selected several highly accomplished ministers, the ministers of the five chariots of learning and wealth stood on the left side, and the envoys of the five kingdoms of Silla, Goguryeo, Wa, Turkic, and Turpan stood on the right side.

Qin Xuan came to the palace gate with the eunuch Feng Zhizhong, Feng Zhizhong stretched out his hand and signaled: "Gongzi Qin, and wait here for His Majesty to summon you!" After speaking, without waiting for Qin Xuan to speak, he walked in with broken steps.

In a moment, a crisp voice came. "Xuan Qin Xuan goes to the palace!"

At this moment, Qin Xuan said that he was not afraid that it would be a lie, swallowed a mouthful of spit, and stepped forward with a hard head. Walking into the main hall and seeing the people on both sides, I was even more apprehensive in my heart, and when I arrived in the hall, I knelt down and said: "Qin Xuan, grass people, meet Your Majesty!" ”

Taizong was not surprised when he saw Qin Xuan seeing him, he couldn't help but be a little puzzled in his heart, thinking that there were many people at the moment, it was not good to ask each other, and said with a smile: "Get up!" ”

After Qin Xuan got up, Taizong spoke again: "Qin Xuan, there are several foreign envoys today who want to compare wisdom with the Tang Dynasty literati!" Seeing Qin Xuan's restrained form, he cheered Qin Xuan up and said, "I think about such a trivial matter, you will not let me down!" Take it easy, but it's just a matter of entertainment! ”

When Qin Xuan heard this, he immediately relaxed nervously and slowly eased his cultivation, and said in his heart: Compare wisdom? I can't guarantee that I'll win! With a roll of his eyes, he opened his mouth and replied: "Back to Your Majesty, although the grass people are only shallow in learning, they will definitely go all out this time!" ”

Taizong laughed and said, "Okay, eldest grandson Aiqing, let's start!" ”

Eldest Sun Wuji took a step forward and said, "Ashina envoy, you can start!" ”

Ashina Lin Yun looked at Qin Xuan sideways, and seeing that Qin Xuan was not very old, he was even more disdainful, took out the glass cup, and blurted out: "Then ask Master Qin to pour this cup full of water, and turn it upside down so that the mouth of the cup is facing down, but the water in the cup cannot flow out!" ”

When Qin Xuan heard such a strange question, he frowned unconsciously, closed his eyes and pondered. After a long time, he finally opened his eyes, showed a smile, saluted slightly, and said slowly: "Ashina's envoy doesn't look down on my Tang people?" ”

Everyone in the hall, including Taizong, looked at Qin Xuan in surprise. Although Ashina Lin Yun really looked down on the Tang people in his heart, he couldn't show it on his face, pretending to have a "puzzled" expression, looking at Qin Xuan and asking, "Master Qin, where do you say this?" ”

Qin Xuan shook his head slightly and said: "Such a simple question, you are embarrassed to say it, if you want to compare your wisdom with the ministers of my Tang Dynasty, who have read poetry and books, aren't you people who look down on me in the Tang Dynasty?" ”

Ashina Lin Yun unconsciously lost his voice and said: "Easy question? ”

Qin Xuan said with a smile: "When I heard this question, I was extremely puzzled, such a simple question, don't say that the ministers, even if I, even if I can answer it as a child playing in the fields of the Tang Dynasty, it is no wonder that no one has taken care of Your Excellency before me!" ”

When Taizong heard Qin Xuan's words, he was very happy in his heart: This kid also knows that raising the Tang Dynasty is teachable!

Ashina Lin Yun was slightly displeased, and said coldly: "Then Master Qin, why don't you just do it for me!" ”

Qin Xuan saluted Taizong and said, "Your Majesty, since Ashina's envoy is suspicious of the grass people's words, it is better to order someone to carry a bucket of water to the temple, and the grass people will operate it on the spot!" ”

Taizong waved his hand and said with a smile: "Today's matter of comparing wisdom is in charge of the eldest grandson Aiqing, I just came to see the excitement!" ”

When the eldest grandson Wuji heard this, he said with a smile: "Then according to Qin Xuan's words!" Then he ordered someone to prepare.

After a while, the two eunuchs brought a bucket of water and placed it in the hall. Qin Xuan took the glass cup from Ashina Lin Yun's hand, walked to the wooden barrel, submerged the glass cup under the water, and after the entire glass cup was filled with water, he grabbed the bottom of the cup and slowly picked it up, and when the cup was about to leave the water, he stopped, turned back to Ashina Lin Yun and smiled: "Ashina envoy doesn't need to get closer, take a closer look?" ”

Ashina Lin Yun glanced at the glass cup in Qin Xuan's hand in surprise, and said helplessly: "Bachelor Qin is talented, I really admire it!" ”

Qin Xuan took out the glass cup out of the bucket and said with a smile: "Your Excellency raises love, in fact, among the thousands of people in the Tang Dynasty, I am just the last person!" ”

Ashina Lin Yun was displeased when he heard Qin Xuan's words, and by the way, he straightened his face and said coldly: "Master Qin, don't be modest, I still have a question, I think you won't answer it!" ”

Qin Xuan smiled slightly, stretched out his hand and signaled, "Your Excellency, please speak!" ”

Ashina Linyun blurted out: "There is a wood that doesn't know its length, and a rope doesn't know its length." If the rope is folded three times, it is one inch shorter than the wood; Fold the rope in half, then it is six inches long, I don't know its wood geometry, its rope geometry? ”

When Qin Xuan heard this, he said in his heart: I'll go, and I'm embarrassed to ask me about the junior high school math questions? After thinking for a while, he blurted out: "The wood is more than one foot and five inches long, and the rope is four feet and more than two inches long, I don't know if it's right?" ”

Ashina Lin Yun was suddenly shocked, and said in his heart: This son has excellent intelligence, it seems that if he doesn't say the most difficult question, I'm afraid he will definitely not be stumped. Thinking of this, he blurted out again: "I still have a question, I'm sure you can't answer it!" ”

Qin Xuan waved his hand directly and said, "Your Excellency's question is too simple, like you, I don't know when you will be able to tell the winner." In my opinion, it is better to ask a question, and if the envoys answer first, who will win, how about it? ”

When several envoys heard this, they each thought for a moment, and then they all nodded and agreed, Qin Xuan saw this, and said in his heart: There are so many problems in the future generations, brother will not take out one or two of them and not make you dizzy? A wicked smile appeared at the corner of his mouth, and he blurted out: "A businessman bought a chicken for eight yuan and sold it for nine yuan." Then I felt that it was not cost-effective, so I bought it back for ten dollars, and finally sold it to another person for eleven dollars, what is his total profit? ”

Looking at the five so-called envoys, Qin Xuan secretly said in his heart: This question, no matter how you answer it, it's all wrong, haha......

A moment later, the Turkic envoy Ashina Linyun took the lead in replying: "Two texts! The first time you sell it, the second time you sell it, you get another penny! ”

Before Qin Xuan could speak, the Silla envoy on the side, Park Qiwang, replied directly: "No, it should be Sanwen!" At the beginning, there were only eight texts, and in the end it became eleven texts, how many are not three texts? ”

When the envoy of the Japanese kingdom, Koji Sugimoto, and the envoy of Goguryeo, Jin Guiquan, heard this, they echoed and said, "Yes, it's Sanwen!" ”

Qin Xuan was still silent, just shaking his head slightly. Taizong and the ministers on the side were also confused at the moment, and couldn't help but set their eyes on Qin Xuan.

Qin Xuan was a little embarrassed by everyone, waved his hand, and said, "No, if it's so simple, how can I move to the top of the main hall to chat with you?" ”

After a long time, the five envoys lost their patience and began to shout: "Then Master Qin, tell me!" ”

Qin Xuan smiled slightly and said, "The first transaction, Bawen buys, Jiuwen sells, and the profit is one; In the second transaction, Jiuwen sold, Shiwen bought, and lost one penny; The third layer of trading, 10 wen buys, 11 wen sells, and the profit is one penny. ”

When Qin Xuanfang said this, the envoy of the Japanese State, Sugimoto Koji, interjected: "That should be an article!" ”

Qin Xuan shook his head and waved his hand, "I haven't finished speaking, you guys will listen to it and talk about it." could have made three cents directly, but this businessman spent three times and made the profit into one penny, didn't he lose two cents? ”

Qin Xuan's flickering, the five envoys were suddenly at a loss, and they all bowed their heads to meditate.

After about a cup of tea, the Turkic envoy Ashina Linyun said: "Master Qin, the answer to this question is ambiguous, it is difficult to convince the public, and it cannot be counted as your victory!" ”

Qin Xuan glanced sideways at Ashina Lin Yun, and said in his heart: Not convinced? Brother dictates all kinds of disobedience, let me think about it, is there a more difficult question in the future. Suddenly thinking of something, he blurted out: "Since that's the case, then I'll ask another question, everyone, listen!" ”

Qin Xuan coughed lightly, and said slowly: "There are three people walking together, and it is getting late, so they go to the inn to stay, and they are told that they will have thirty wen a night, and each of the three of them will give ten wen to make up thirty wen and hand it over to the shopkeeper." Later, the shopkeeper felt that the three of them were pitiful, so he wanted to only accept twenty-five wen, and took out five wen to let the shopkeeper return it to the three. The shopkeeper privately exchanged two papers, and then returned the remaining three to the three of them in one penny each. In this way, at the beginning, the three of them each paid ten yuan, and now they return one yuan, that is, ten yuan to one, nine yuan, three people are twenty-seven yuan, plus the shopkeeper two yuan get two yuan, a total of only twenty-nine yuan, I don't know where the other penny goes? ”

The five envoys' heads suddenly grew bigger: yes, where did the penny go? For a long time, he still had a bitter and hateful expression, staring at Qin Xuan.

Qin Xuan smiled slightly, and said in his heart: Now I know that my brother is powerful, my brother is a top doctor in the Tang Dynasty, specializing in treating all kinds of unsatisfactory diseases......
