The only thing Heir of Prince Xiang couldn't figure out was how much enmity and hatred he had with this Poet Immortal, Word Sage, that it was worthy of him tarnishing his famous name like this.
What Heir of Prince Xiang doesn't know is that Xu Yi doesn't care about Poet Immortal, Word Sage's so-called reputation at all, and tramples on Heir of Prince Xiang like this just to return Son of Heaven of Great Yue's favor.
Who told Heir of Prince Xiang that he had too much limelight before, and if he didn't completely step him into the mud, Xu Yi would feel sorry for Son of Heaven of Great Yue's excuse.
However, from the current point of view, Heir of Prince Xiang has not been trampled hard enough. Xu Yi added, "Xu also has two doubts that cannot be solved, and I would like to ask the prince to give me some advice."
Heir of Prince Xiang You suddenly came to his senses and suddenly realized that even if Xu Yi answered both questions correctly, he might not have no chance at all. When it came to quick wits, none of the wise men in Prince Xiang's palace could beat him.
If Xu Yi can solve his problem, then he must not be able to solve Xu Yi's problem.
Even if only one is solved, it will clear up the confusion for Poet Immortal, Word Sage. The face that was lost before can be picked up together.
But he was still worried about the stone-water theory, and he immediately said, "The right and wrong are all open to public opinion. Sir, I don't even care about my reputation, I want to win someone, and I have nothing to say. Now, I'll ask you, sir, to give me a question, and I'll give you my answer."
Xu Yi said, "Your Majesty, please listen to the question."
Unexpectedly, as soon as he spoke, the whole place was filled with white paper and pens flying around. Even in front of Son of Heaven of Great Yue's throne, there was a new wide table with imperial pens and ink placed on it.
Obviously, this unique battle of wits has aroused everyone's interest.
What's more, while Xu Yi and Heir of Prince Xiang were arguing, several princes went to the small yellow gate to buy basins, stones, bowls, and water to verify what Xu Yi said.
When the stone was submerged in the water and the water line clearly penetrated the red line previously carved on the bowl, the whole audience roared with joy.
What are the internal causes? It has been cut into pieces, but no one can fully understand its reasons.
At this moment, I heard that Xu Yi, the world-famous Poet Immortal, Word Sage, and the most wise man in the world, was going to write a test for the college entrance examination. The sensational effect was far greater than that of Heir of Prince Xiang.
What's more, countless people concluded that this battle of wits will be recorded in the history of Dai Viet literature, and everyone had a wonderful feeling of participating in history.
But I heard Xu Yi say, "In Xu's hometown, there are two small islands, one is Peach Blossom Island and the other is Hero Island. There are seven wooden bridges connecting the two small islands on both sides. When Xu was young, he often played and traveled between the islands. Occasionally, one day This time, Xu wondered if he could start from anywhere between the two islands and the two banks, pass each wooden bridge exactly once, and then return to the starting point. Since he discovered this fun at the age of twelve, for a total of six or seven years, Xu has walked back and forth on the seven bridges hundreds of times, but he still has no solution. Now I ask Heir of Prince Xiang to explain it to Xu."
After saying this, he asked the eunuch for a pen and paper, and made a sketch of the two islands, the two banks and the seven bridges in front of everyone, and announced it to everyone.
This question just came up, and the whole place was in a state of shock. No one expected that at this critical moment, Poet Immortal, Word Sage would actually come up with this question that was almost a joke.
Compared with the stone floating in water, we can clearly see the mystery. This question is basically about routing. You only need to try it a few times and you will always get the result.
Even though Heir of Prince Xiang had already thought about it, he couldn't help but feel happy when he suddenly heard this question. He didn't doubt that there was a profound meaning in the question Xu Yi, but he could just imitate it and follow the example of Xu Yi in answering the stone-water question, which only gave the result but not the meaning.
So he only had to repeat the experiment, and he didn't need to delve into the hidden truth.
When he was secretly happy, he heard Xu Yi say, "Just now, it only 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 Xu's question. As Mr. Chen said, in order to avoid wasting time, it is necessary to compete with one's wits. If it takes too much time, it will violate the original intention of choosing this competition. I don't know what the prince's intention is."
"Someone will use half a stick of incense, no, at most one stick of incense. If one stick of incense is not answered, it will be considered as a loss."
Xu Yi raised the theory of time, which made Heir of Prince Xiang feel reassured, and he concluded that Xu Yi was worried about his repeated experiments and obtaining the results.
He secretly thought to himself that this time he had to sweep away his depression and make a huge Xu Yi fall. With his quick wit, the effort of others to test once was enough for him to test ten times, and he had a photographic memory. It was incomparable to paper and pen, and he relied entirely on mental arithmetic.
This stick of incense was enough for him to test thousands of times. How could a few bridges withstand thousands of tests?
Heir of Prince Xiang After saying this, someone from the small yellow door took out the incense burner, placed it in the dark, lit a commercially available timing incense stick, and then left.
Long before lighting incense at Xiaohuangmen, Heir of Prince Xiang sat cross-legged, closed his eyes and heard nothing, and started rapid mental calculations in his mind.
Seeing that one-third of the stick of incense had been burned, the expression on Heir of Prince Xiang's face was like a thrilling scene, from the initial tranquility to the ferocious face, and finally to the profuse sweating.
Xu Yi stared at the incense quietly, feeling at ease in his heart. He was not worried about Heir of Prince Xiang solving this problem at all, but it was therefore an unsolvable problem.
This question may sound simple, but it is profound and unfathomable. It is exactly the famous Seven Bridges Problem in the history of mathematics in previous generations.
Finally, the problem came to the world-famous mathematician Euler. Even Euler went through a long process of deduction and finally proved that this problem had no solution, which in turn gave rise to a branch of mathematics, graph theory and topological geometry.
Even if Heir of Prince Xiang is extremely talented and his mathematical skills are far superior to that of Euler, the great sage from the previous life, trying to give the answer within a stick of incense is nothing short of a fantasy.
The scenery on Heir of Prince Xiang's face was gradually interpreted to the extreme, as if huge waves gathered into a storm. At that moment, everyone stopped experimenting and looked at Heir of Prince Xiang. Suddenly a stick of incense was about to burn out, and Heir of Prince Xiang suddenly spat out a mouthful of blood and fell to the ground.
Chen Guanhai rushed forward in a hurry, raised his hand and put several pills into Heir of Prince Xiang's mouth. In a moment, Heir of Prince Xiang's face, as white as gold paper, turned red. He raised his eyes and glanced at Chen Guanhai, and said gloomily, "Sir, why can't you solve such a simple problem? It's just one step away, just one step away..."
Chen Guanhai said, "There must be some ingenuity to this question. If Mr. Xu can solve it in public, there must be some mystery."
At that moment, Heir of Prince Xiang yi Gulu stood up, cupped his fists at Xu Yi and said, "Please Mr. Xu give me some advice!"
"What can I teach you?"
Xu Yi is smiling.
Heir of Prince Xiang's handsome face turned cold, "Sir, why bother asking the question knowingly? I admit that I can't solve this question. Please tell me the answer."
Xu Yi smiled and said, "Xu is only responsible for setting the questions, not solving them. Since the Crown Prince solved the two couplets that Xu came up with, he should know Xu's routine. Speaking of which, Xu is not smart, so he relies on these questions to protect his name. If he sends all the answers, he will be embarrassed if he meets someone like the Crown Prince to ask for advice again."
