mad dragon son-in-law

Chapter 517

"Should we use the principle of leverage?" The little girl pointed to the gap and suggested: "There is a gap here, find something to stuff it in, and then we will pry it open together."

"It won't work." Xiao Feng shook his head, directly dispelling the little girl's whims.

Give me a fulcrum, and I can pry up the earth!

This is a very famous quote from Archimedes, written into textbooks.

But the reality is, you have to find the fulcrum first, and then the leverage has to meet the standard.

Nowadays, what can be used as a lever at hand is just a trekking pole, but facing such a thick rock, it is tantamount to prying an elephant with a matchstick. It is purely delusional.

At this moment, Su Yuzhuo suddenly said: "There seems to be a pattern on it."

As he spoke, he shone the flashlight on the rock.

When Xiao Feng and others looked at it, they found that there was a not-so-obvious depression on the rock, and the pattern on it looked a bit weird, giving people an awkward feeling like deliberately disrupting it.

"I see!" Sun Shijie suddenly realized: "No wonder my family asked me to remember a picture since I was a child. Looking at the outline, this is what the picture looks like after it is disassembled."

"That is to say, this is also a mechanism, as long as you spell out its original pattern, you can open the next path?" Xiao Feng thoughtfully.

For a moment, everyone's eyes couldn't hide their excitement.

After all, after walking so far, after going through many hardships and tribulations, finally seeing the dawn, and it seems that as long as the mechanism in front of him is cracked, he will be able to see the light of day again.

Under this premise, no matter how good the concentration is, it is inevitable that there will be gaffes.

"You restore it." Xiao Feng stepped aside and motioned for Sun Shijie to come forward.

Sun Shijie put down his backpack and walked in front of the rock, his face immediately became ugly.

Because the mechanism in front of him is very similar to the educational jigsaw puzzle toys played by children. It is composed of squares, and there is only one vacancy in the whole picture that can be moved.

However, the problem is that most children play with nine grids and eight pictures, no matter how difficult it is, just try a few more times.

As for the picture in front of him, Sun Shijie counted it. There are 81 grids and [-] movable squares. This is the rhythm that makes people worry to death.

However, in this case, it can only be hit and miss.

"call……"

Letting out a long breath, Sun Shijie tried to move the puzzle in front of him.

The appearance of the pattern does not need to be recalled too much, it has long been deeply ingrained in the mind, and it can be used quickly.

……

Half an hour later, Sun Shijie was already sweating profusely, not tired, but anxious.

Because it took half an hour, he managed to spell out the top two patterns, and it could be seen that it was the head of a koi.

But he soon discovered that the jigsaw work could not go on. If he wanted to put together the bottom one, he had to mess up the two upper ones that had already been put together.

"No, I won't be able to spell it out every ten days and a half months." Sun Shijie wiped the sweat from his face, looking very distressed.

Xiao Feng and the others couldn't say anything, after all, knowing what the original picture looks like, and putting together the messed up original picture are two completely different concepts.

Su Yuzhuo comforted: "Uncle Sun, don't worry, I think you can try to draw the original picture first, and then we can divide each piece of it according to the original picture, and work together to find a way Come."

Sun Shijie glanced at Su Yuzhuo, and said calmly, "This is also an idea."

After speaking, he took out the pen and paper from his bag, and drew the pattern on the paper according to the appearance in his memory.

After 10 minutes passed, a drawn pattern came into view.

The content of the painting is a koi swimming in the lotus pond, next to it is a pavilion, there are a few willows on the bank, and there are even a few dew on the lotus leaves. The details are quite rich.

Just as Sun Shijie was tearing off the paper and wanted to draw the grid according to the proportions, Lu Yao smiled and said, "Don't be so troublesome, I will draw it on the computer and then divide the proportions, which will be faster."

"Okay." Sun Shijie agreed straight away.

For a person of his age, he always felt that the ratio determined by the computer must be more accurate than that of humans.

I don't know what's going on, but I just feel very powerful.

Lu Yao's efficiency has always been very high. Sun Shijie took 10 minutes to draw with a pen, but she drew it completely on the computer, which only took about 3 minutes.

Then, add grid lines to the pattern.

After finishing all this, Lu Yao took a look at the pattern on the rock, and after comparing it several times, she rotated the screen and showed it to everyone: "It's almost like this."

Xiao Feng rubbed his chin, and immediately realized that something was wrong, pointed to the lotus leaf and the pavilion: "These squares are exactly the same."

Everyone obviously noticed that something was wrong. The exact same pattern sounds like it can be anywhere, but compared to the whole, the position cannot be messed up, and it must be where it should be.

"Can you make a program to simulate a trajectory that spells out a complete pattern?" Su Yuzhuo asked.

Lu Yao shook her head: "No, it may be possible outside, but there is no internet here, and many technologies cannot be realized."

The problem seems to be back to the original point. Although I have seen the complete appearance of the pattern, there is still no breakthrough.

After being silent for a while, Lu Yao gave a solution: "How about I write a simple program to retell the puzzle on the rock, and then we all figure out a way together to see if we can spell it out?"

Everyone looked at each other and nodded at the same time: "That's the only way."

Next, the group divided into two groups and began to get busy.

In front of the rock, Sun Shijie took out his cigarette pouch, and while smoking, he argued with Master Jiu and Zhao Guoan.

But Xiao Feng, Xiao Yatou and others surrounded the computer and made continuous attempts.

After tossing and tossing for more than 20 minutes, Xiao Feng suddenly came to his senses, stopped and said: "I have a question, even if we put together the puzzle, what's the use?"

Everyone was taken aback for a moment, and then they suddenly realized.

Yes!

So what can I do if I spell it out by myself?
The organ still can't be opened.

"The program I made can store the movement trajectory, and when the time comes, it will follow us here..." After speaking, the voice has become smaller and smaller, obviously reacting with hindsight.

A very simple truth.

Although the two sides are cracking simultaneously, the number and direction of the moving squares are not synchronized. The computer can save the moving order of the squares, but obviously not on the rock.

"Snapped!"

After shutting down, Lu Yao closed the computer.

The faces of Xiao Feng and others were also a little ugly. It was useless to toss for so long. If they can still maintain a good mood, then they are too heartless.

"Is there any other way?" Lin Zhiyan looked at Xiao Feng and asked.
