Chapter 700: Seven bridges

The only thing that King Xiang Shizi couldn't figure out was how much hatred and hatred he made with this poetry and poetry, which deserves his reputation.
What Xiangshi Shizi didn't know was that Xu Yi didn't care about the so-called English name of this poetic sage, so he stomped on Xiangshi Shizi only for the sake of returning to Tianyue Tianzi.
Who said that the king of Xiang Xiangshi had too much prestige and didn't step him into the mud completely, Xu Yi felt that he couldn't help Da Yue Tianzi open a golden mouth.
However, from the current point of view, King Xiang Shizi has not been trampled hard enough, Xu Yi said, "Xu also has two puzzles that cannot be solved, and he also asks Shizi to enlighten me."
King Xiang's son returned to God, suddenly realized that even if Xu Yi answered all two questions correctly, he might not have no chance. When it comes to wit, a group of wise men in King Xiang's house did not beat him.
Xu Yi was able to break his problem, but he certainly couldn't solve Xu Yi's problem.
Even if only one was unlocked, it was a confusion for the poetic fairy sage. The previously lost face can be picked up together.
But he still thought about the stone water theory, and immediately said, "Right and wrong, his own opinion, and the sir did not even care about his reputation, but also won, and there was nothing to say. Now, Ask Mr. to answer the question.
Xu Yidao, "Shizi, please listen to the question."
Unexpectedly, he was speaking out. The scene was covered with white paper and his pen moved. Even before the throne of the Dayue emperor, he opened a new wide case and set the pen and ink.
Obviously, this ingenious intellectual battle has aroused everyone's interest.
What's more, while Xu Yi and King Xiang Shizi argued, several princes set up pots, stones, bowls, and water with Xiaohuangmen to verify Xu Yi's words.
When the stone was submerged in the water, the waterline obviously dipped into the red line that was previously recorded in the bowl.
The inner cause is noisy, but no one understands it.
At this moment, I heard that Xu Yi, the famous poet and immortal sage of the world, and the first wise man in the world, had to write a test for the test. This sensational effect is far more than that of King Xiang.
What's more, countless people have concluded that this intellectual battle will be carried into the history of Dae Viet, and everyone has a wonderful feeling of participating in history.
But I heard Xu Yidao, "In Xu's hometown, there are two small islands, a peach blossom island and a knight island. There are seven wooden bridges that connect the two islands and connect the two shores. Xu was often on the island when he was young. Play and interact with the island. Occasionally, Xu thought whether it would be possible to start from any place between the two islands and the two shores, and pass each wooden bridge exactly once, and then return to the origin. Found at the age of twelve At the beginning of this fun, for a total of six or seven years, Xu Moulai went back and forth over the Seven Bridges a hundred times, and it is always inextricable. Now, please ask the son of King Xiang Xiang to solve the confusion. "
Having said that, he asked the to come to paper and pen, and publicly dropped the sketches of the two islands and the two banks and the seven bridges to announce the crowd.
This question came out, and the scene was full of bangs. No one expected that at this critical moment, the poetic fairy sage actually came up with this almost joke question.
Compared to the stone floating water, the mystery can be clearly seen. This question is basically a line. You only need to try a few times to get the result.
Rao Shixiang has raised his mind. He suddenly heard this question and couldn't help it. He didn't doubt the deep meaning in Xu Yi's question, but he could draw a tiger as a cat and learn Xu Yi's answer to the stone water question. Give results, not justice.
Therefore, it is only necessary to repeat the experiment, and the hidden reason is not necessary for him to delve into it.
While he was secretly happy, he heard Xu Yidao, "Suitable, answer Shizi's question, it takes less than half a tea time before and after. I do n’t know how long it takes Shizi to answer Xu's question. It ’s more wise than fighting, if it ’s used too much, it may be against the intention of choosing this fighting, and I do n’t know what the world ’s intention is.

"Some would use a half-pillar incense, no, at most one incense, if one incense is not answered, it is considered a loss."
Xu Yi put forward the theory of time, and made Xiang Xiang Shizi calmly determined that Xu Yi was worried about his repeated experiments and achieved results.
He secretly said in his mind that he had to swipe away suddenly and lift Xu Yi a big heel. With his swiftness, others would try the kung fu, enough for him to test it ten times, and he would never forget it.
How could this incense effort be enough for him to test thousands of times and how many bridges can withstand thousands of tests.
When the King of King Xiang's words came to an end, a small yellow door held out the incense burner and placed it in the dark to ignite the general-purpose timing incense on the market and then receded.
Long before Xiaohuangmen lit the incense, Xiang Wang Shizi sat cross-legged, closed his eyes and heard the news, and started a rapid mental calculation in his mind.
Seeing that one third of the incense was burned away, the expression on King Xiang's face was like a thrilling scene, from the initial tranquility to the later noodles, and finally to the last sweat.
Xu Yijing stared at Xianxiang with peace of mind. He didn't worry about Xiang Xiangshizi solving this problem, but it was an unsolvable problem at all.
This question is simple, but it is inscrutable. It is the famous Seven Bridges problem in previous mathematical history.
In the end, it came to Euler, the world-famous mathematician. It was after a long deduction that Euler finally proved that the problem had no solution, and then derived a branch of mathematics, graph theory, and topological geometry.
Even if King Xiang's son had the talent for heaven, his mathematical skill far surpassed that of the great wise man Euler in the previous life. It was tantamount to give the answer in a scent of incense.
The scenery of King Xiangshi ’s face gradually evolved to the extreme, as if the giant clouds converged into a storm. At the moment, everyone stopped testing and looked at that Xiangxiang Shizi. Suddenly, a joss stick will burn out, and King Xiangzi spit out A bite of blood came and fell to the ground.
Chen Guanhai rushed forward, raised his hand and sent several elixir into the mouth of King Xiang Shizi. After a while, the face of Xiang King Shi Zi was as white as gold paper, with blood color, raised his eyes and scanned Chen Guanhai, Shen Yu said, "Sir, Why is it so simple that if one can't figure it out, it's one step behind, one step behind ... "
Chen Guanhai said, "This question must be a coincidence. Mr. Xu can come out in public and there must be a mystery."
At present, the King Xiang Xiangzi mumbled and stood up and rushed to Xu Yi's fist, "Please ask Mr. Xu for advice!"
"Teach me!"
Xu Yi was smiling.
Xiang Wang Shizi Jun faced a chill, "Mr. Why did he ask this question knowingly, and this question admits that it cannot be solved, and asks Mr. to tell the answer."
Xu Yi laughed, "Xu is only responsible for solving the problem, not responsible for solving the problem. Since Shizi has unlocked the two couples of Xu, he should know Xu's conventions. Then, Xu's mind is not good, so rely on this A few questions, the name of the security order, if all the answers are sent out, and then meet a person like Shizi to ask, would it be embarrassing. "
