Wu Cheng began to explain according to the question that in addition to the starting point, every time a person enters a piece of land from a bridge, he also leaves this point by another bridge.

Therefore, two bridges are counted at each point of travel, and the line that leaves from the starting point and the line that returns to the starting point at the end is also counted as two bridges, so the number of bridges connecting each land to other land must be even.

Since the Seven Bridges have four singularities, it is impossible to find a route that passes through seven bridges, but each bridge is only taken once.

After Wu repented, Lin Qiu and the others were stunned, feeling that everything they had learned before had become as smelly as shit.

Although he couldn't digest Wu Cheng's point of view at the first time, his intuition told Lin Qiu that what Wu Cheng said was right!

When he was still looking down and calculating, everyone had already begun to summarize the rules, and the two were obviously not at the same level.

Even, the other party actually summarized the law into a theorem, if this kind of theorem can be popularized in the Nine Shadows in the future, I don't know how much brainpower and time can be saved.

As for Hengjiushan, he is still trying to do it.

Heng Jue looked at Wu Cheng again, and there was a hint of admiration in his eyes.

A man like this who is young and talented is simply the golden beetle son-in-law of the treasure boys!

Besides, this person is deeply appreciated by the patriarch, and if I marry him, the patriarch will probably praise me greatly!

In the face of love, age is not a problem at all, although this age difference is a bit big...

But big also has big benefits, as the saying goes:

Female junior, hugging gold bricks. Thirty women, send the country!

The female college is three hundred, and the elixir is sent. There are three thousand female colleges, ranking in the immortal class!

The female college is 30,000, and the queen mother feeds her. 300,000 women, standing in front of the Buddha!

The female college is three million, and you have the final say in the fairy world. There are 30 million women's colleges, and the Six Realms are up to you!

The female college is 300 million, Pangu is your brother!

Although you can't let Pangu be your brother, you can still do it by letting Hengjiushan be your grandson!

Moreover, with Heng Jiushan's qualifications and conduct, he will inevitably take over as the next head of the Nine Shadows Admiral.

In fact, if it weren't for the pressure of these elders, the current head would have wanted to pick and choose not to do anything, and would have devoted himself to studying arithmetic.

Thinking about it like this, Heng Jue didn't feel that Wu regretted suffering at all, and even felt that the other party had picked up a big bargain!

Lin Qiu's mind was spinning rapidly at this time, but he couldn't find the crux of the problem, "Since this is the case, why did the owner of this ruin design such a formation to confuse future generations?"

Puzzled, and in the end, helplessly, Lin Qiu cast his eyes on Wu Cheng for advice.

Wu Cheng thought for a moment and said, "Perhaps, I just want to meet a person who is extremely intelligent, dare to break through the convention, and find the eighth bridge hidden in the formation!"

The words "Eighth Bridge" are like the voice of the Nine Heavens, yes!

You can't walk all seven bridges in one sitting, but one more bridge will do!

And the real entrance is actually hidden in this eighth bridge!

it! Ruthless! So cruel!

Lin Qiu's mood at this time is probably only one sentence!

But the old man is uneducated,

A sentence to go to the world!

If you ask where the Seven Bridges come from,

Know where to go in the Eight Bridges!

The same is the end of the world code word dog,

There is no collection tip!

"Fellow Daoists, preach the grace of teaching and solving doubts, please accept Lin Qiu's worship!"

From a small friend to a Taoist friend, it can be seen that Lin Qiu's attitude towards him has changed dramatically.

"Lin Lao's words are serious!

There is a kind of worship, that is, I don't know where you are good or what you are good at, that is, I worship you!

It's the same as chasing stars, you don't even know what you're doing, as long as someone is chasing you, you follow it.

This situation is like Kong Haoda and others at the moment.

Everyone is not good at arithmetic, but they can only understand a little bit about it.

They couldn't appreciate the difficulty of this question, but when they saw Lin Qiu's appearance, they felt that Wu Cheng was very awesome!

In fact, Wu Cheng's awesomeness far exceeded the upper limit of their imagination, after all, it was the crystallization of the wisdom of the whole earth.

The two sides have already asked two questions, Wu regret has won all, on the other hand, although Lin Qiu has been defeated, he is in a really good mood.

First, he solved the problem he had not solved, and second, he finally found a Taoist friend who counted all the way, and he could communicate more in the future.

"There is a third question, are we still comparing?" Wu Cheng said tentatively.

You can't be too much, stay a line in life, and see each other in the future... Although it is impossible to be with Lin Qiu in the future, but Heng Jue next to him, Wu Cheng can teach the other party a lesson or two!

Advice, looking at your middle finger and ring finger, hehe, this can be regarded as a tiger wolf!

Lin Qiu said solemnly, "Compared to a person who counts, one is one, and two is two.

Besides, it is also a blessing to be able to learn from Taoist friends, although it is still honorable!

However, with the old man's question bank, there is no question that can stump Taoist friends, and I am not ugly.

Then in this last game, the three of us can work together to solve the problem of Daoyou. Okay?"

"Lin Lao is happy, I have a gadget here, it's not a competition, it's just a communication, please taste one or two together." ”

As he spoke, Wu Cheng took out a wooden cube from behind him, the cube can be rotated, and there are nine small squares on each side, and the small squares are engraved with nine identical numbers, which are the Rubik's Cube of the earth!

Everyone gathered around to look at this strange thing, and they couldn't figure it out for a while.

Wu Cheng scrambled the Rubik's Cube, "The way this thing works is to return all the numbers to the previous face." ”

"Six faces, each with 9 small faces, this kind of design can be called the work of a giant in the contemporary agency world!" Lin Qiu carefully took the Rubik's Cube and muttered to himself.

Then he fiddled with himself, and after some turning, he could barely put together one side, but the other sides couldn't be put together at all.

Heng Jiushan was just about to stretch out his hand to try it, but was persuaded by Lin Qiu's eyes, your master hasn't played enough, you kid still want to get started?

Lin Qiu tossed to no avail before giving Hengjue and Hengjiushan.

When the two of them saw Lin Qiu fiddling with it before, they already had some ideas in their hearts, but when they practiced, they found that the distance between theory and practice was more than just a pair of hands.

Wu Cheng saw that the three of them fiddled around for a while and didn't figure it out, and thought to himself, if it continued like this, I was afraid that he would have to take care of lunch.

Then he said, "Why don't I demonstrate it, and the three of you can take a look at it before you make a move, okay?"

Although he was a little embarrassed, Lin Qiu still returned the Rubik's Cube to Wu Cheng.

Wu Cheng liked to play the Rubik's Cube very much when he was a child, although he couldn't finish it in ten seconds, but there was no problem within 60 seconds.

Rubik's Cube, as long as you find a pattern, it is very easy to fight, and the rest is just a matter of time.

Taking the Rubik's Cube, Wu Cheng looked at the numbers on the next six sides and put his hands on the Rubik's Cube......
