The only thing Prince Xiang couldn't figure out is how much hatred he had with this poet and saint, and what he deserved to be so defamatory to his reputation.

What Prince Xiang didn't know was that Xu Yi didn't care about the so-called heroic reputation of the poet and lyrics. He slapped the prince Xiang so hard just to repay the Emperor of Dayue.

Who told the prince of King Xiang to take too much limelight before and did not completely step on him into the mud, Xu Yi felt sorry for the Emperor of Dayue to open a golden mouth.

However, as far as the point is concerned, the prince of King Xiang is still not trampled hard enough. Xu Yi said again, "Xu also has two doubts and cannot be solved. I would like to ask the prince for advice."

Prince Xiang You came back to his senses and suddenly realized that even if Xu Yi answered all the questions correctly, he might not have no chance. Regarding the quick wisdom, no wise men in the Xiang Palace could beat him.

If Xu Yi can solve his problems, can he definitely not solve Xu Yi's problems?

Even if you only unlock one, it will open up the confusion of the poet and lyrics. You can pick up the face you lost before.

But he was still worried about the Shishui theory and immediately said, "The right and wrong are public opinion. The gentleman doesn't even care about his reputation and wants to win someone. He has nothing to say. Now, please ask the gentleman to give a question, and he will give it a try."

Xu Yi said, "Prince, please listen to the question."

Unexpectedly, he said that the whole place was filled with white paper and his pen was filled with pens. Even before the throne of the Emperor of Dayue, a new wide table was placed and a royal pen was placed.

Obviously, this unique battle of wit has aroused everyone's interest.

What's more, just as Xu Yi and Prince Xiang were debating, several princes took the small yellow gate to buy basins, stones, bowls and water to verify what Xu Yi said.

When the stone was submerged into the water, the water line was obviously soaked by the red line burned in the bowl body, and the whole seat screamed with a loud bang.

What is the internal cause? It is already noisy and cut into pieces, but no one can understand the truth.

At this moment, I heard that Xu Yi, a famous poet and lyricist in the world, was the most wise man in the world, wanted to give a test. This sensational effect was far superior to the prince of King Xiang.

What's more, countless people have concluded that this battle of wisdom will definitely be included in the literature and history of Dayue, and everyone has a wonderful feeling of participating in history.

But he heard Xu Yi say, "In Xu's hometown, there are two small islands, one Peach Blossom Island and one Xiake Island. There are seven wooden bridges that connect the two islands and the two sides of the straits. When Xu was young, he often traveled and traveled between the islands. By chance, Xu thought about whether he could start from any place between the two islands and the two sides of the straits, passing each wooden bridge once and then returning to the origin. Since he discovered this interest at the age of twelve, in total, Xu has traveled back and forth hundreds of times to seven bridges, but it is always unsolvable. Now I ask the prince of Xiang to answer his doubts on behalf of Xu."

After saying that, he asked the eunuchs to come and paper, and to leave the sketch of the two islands and the two sides of the straits and the seven bridges in public, and declared to everyone.

The topic was just released, and the whole audience was filled with a bang. No one expected that at this critical moment, the poet and lyricist actually came up with this almost joking topic.

Compared to the rock floating in the water, the mystery can be clearly seen. This question is simply a line. You only need to try it a few more times and you can always get the results.

Even though Prince Xiang had already raised his mind, he couldn't help but be happy when he heard this question. He did not doubt that Xu Yi's question had a profound meaning, but he could draw a picture of it and learn from Xu Yi to answer the question of Shishui, and only gave the result, not the meaning.

So he just needs to repeat the experiment, and he should not go into the secret truths.

He was secretly happy, but listened to Xu Yi, "Just just now, I took less than half a cup of tea to answer the prince's question. I don't know how long it will take for the prince to answer the question. As Mr. Chen said, in order to avoid spending time, we can fight quickly. If we use too much, it would be contrary to the original intention of choosing this battle. I don't know what the prince intended."

"I just used half a stick of incense, no, at most one stick of incense, and if one stick of incense is not answered, I will be considered a loss."

Xu Yi's proposal of time made Prince Xiang feel relieved, and he believed that Xu Yi was worried about his repeated experiments and achieved results.

He thought to himself that this time he had to let go of his depressedness and make Xu Yi look like a big fuss. With his urgent wisdom and the effort of others to experiment, it was enough for him to experiment ten times, and he would never forget everything after reading it. He was even more incomparable with paper and pen, and it all relied on mental calculations.

This incense stick of effort was enough for him to test thousands of times. How could a few bridges stand the test thousands of times?

After the prince of King Xiang finished speaking, a small yellow door took out an incense burner and placed it in the dark, lit the time-calling incense used in the market, and then retreated.

Long before the little yellow gate lit incense, Prince Xiang sat cross-legged, closed his eyes and heard it, and his mind was quickly arithmetic.

Seeing that one third of the incense had burned away, the expression on Prince Xiang's face was like a thrilling scene, from the initial peace to the ferocious face of the later, and then to the end of sweating profusely.

Xu Yi stared at Shinxiang quietly, feeling at peace in his heart. He was not worried that Prince Xiang would solve this problem, but it was simply an unsolvable problem.

This question is simple to say, but it is unfathomable. It is the famous Seven Bridges problem in the history of mathematics in previous lives.

Finally, it came to Euler, a world-famous mathematician. Even Euler finally proved that there was no solution to this problem, and then it was derived a branch of mathematics, graph theory and topological geometry.

Even if the prince of King Xiang is talented and his mathematical skills are far superior to those of the wise Euler in his previous life, he would give the answer in one stick of incense, which is like a fantasy.

The scenery on Prince Xiang's face gradually became the ultimate, as if the huge storm gathered into a storm. Everyone stopped experimenting and looked at Prince Xiang. A stick of incense was about to burn it out. Prince Xiang suddenly spit out a mouthful of blood and fell to the ground.

Chen Guanhai hurriedly stepped forward and raised his hand to put several pills into the mouth of Prince Xiang. Suddenly, Prince Xiang's face turned white like gold paper, turned blood. He raised his eyes and glanced at Chen Guanhai and said in a deep mood, "Sir, why is such a simple question? It's just one step away, one step away..."

Chen Guanhai said, "This question must be clever. If Mr. Xu can take it out in public, it must be mysterious."

At that moment, the prince of Xiang, Gulu, stood up and clasped his fists at Xu Yi and said, "I would like to ask Mr. Xu for advice!"

"What are you giving me!"

Xu Yi smiled.

Prince Xiang's prince Jun looked cold, "Why did you knowingly ask this question? I admit that I can't figure it out. Please tell me the answer."
