The first link, "Jigsaw Puzzle", is not difficult for Li Fan (only for Li Fan), especially for the first step of the development of spatial polyhedral structure, which he is particularly good at.

When it picked up the polyhedron prop, the whole polyhedron was instantly tiled into a plane expansion diagram in its mind, and the size of the 34 faces that make up the polyhedron, the angles between the edges, and the direction of the angles were all clearly imprinted.

In just about 10 seconds, Li Fan "banged" and dropped the polyhedron props and walked quickly to the prop room behind him, which frightened Lin Xiaofeng and stunned the audience in the hall!

It's too fast, it's too fast after all!

What is the concept of 10 seconds, Li Fan seems to just look at it casually, and then throw the props away and live!

This is very simple for Li Fan, compared with the previous project [Thousand Variations Origami], which deduces origami works based on folds, it is simply easy.

But it's too hard, it's too shocking, it's incredible!

"Wow, when you drop the props, you're so handsome!"

"Chic, coquettish!"

"Li Fan is awesome!"

……

Guo Ming asked uncertainly: "Has Li Fan really come up with a flat plan?"

Doctor Chen analyzed: "Yes, it should be right, with my understanding of Li Fan, there is basically no obstacle to him in this level of spatial ability examination, our question focuses on the back, and the part of assembling the plane expansion diagram is the most difficult!"

Yao Qian asked, "If it is normal, how long will it take to complete?"

Doctor Chen said: "I can't give a specific time at all, you think, the plane of the prop is at least composed of more than 30 faces, and each side can be composed of different combinations of patterns in the prop house.

Therefore, there may be an infinite number of combinations of the correct answer for a player to spell out a flat unfolding diagram, and any combination can pass the level and be handed over to their teammates for the next round of challenges!"

Sun Feifei said: "Oh, although there are many kinds of correct answers, players should choose relatively simple numbers for their teammates, which is conducive to the final challenge!"

Doctor Chen nodded: "Yes, that's what it means, the key is that the player never knows if his combination is the best solution!"

Unless he can find all the answers!"

Sun Feifei shook her head violently, "How is it possible?

The eyes of several guest teachers all focused on Li Fan's back, and at this time, he had already walked into the prop house and started his own challenge.

He started from one side, raised his head and looked at it carefully, his gaze lingering among the various patterns hanging from the ceiling, and then he walked lightly.

Countless graphic information crashed into his eyeballs, quickly filtered through his mind, and when he walked from one side of the prop house to the other, his brain had firmly locked on the location of the 198 patterns, which were all the "parts" that could make up the plan unfolding.

Observing from one side to the other, 3 meters wide, 5 meters long, and 400 patterns, Li Fan completed the first round of observation in just 2 minutes.

The exclamations in the recording hall resounded! Glance is a typical "Li Fan glance" again!

Li Fan took a deep breath, the first time he had just observed, he had already completed the observation of the pattern form, but this was far from enough, this was the first step of the long march!

Each hanging pattern has a number and a number on it, and the number on the pattern is the key to success or failure.

Li Fan turned around and began the second stage of observation.

Because 202 patterns were excluded, Li Fan eliminated the interfering patterns in the second round of observation and started directly from the effective patterns, which greatly improved the efficiency.

He stopped and stopped, kept looking at the digital information on the pattern above his head, and when he just took two small steps, Lin Xiaofeng's figure appeared in the afterglow.

Lin Xiaofeng also completed the observation of polyhedra at this time, and just ran into his prop house.

Li Fan didn't expect Lin Xiaofeng to be quite fast, he gathered his mind and continued to make his observations.

Time passed in a flash, and it took about two minutes and 30 seconds for Li Fan to complete the second round of observation.

Then, seeing Li Fan standing motionless, he closed his eyes again.

Li Fan closed his eyes again!

Lin Xiaofeng's sky is dark!

There was a very interesting scene on the stage, Li Fan, who was as quiet as a "virgin", stood in place and entered his own world, while Lin Xiaofeng moved like a rabbit, and he was a rabbit who was robbed of a carrot.

She ran around the prop room in a panic, eagerly pulling the pattern down from the roof of the shed, trying to piece together the pattern, but also failing to do so.

"It's over, the girl is panicking!"

"Calm down, girl, don't worry!"

"But what is Li Fan doing? After glancing back and forth twice, why did he close his eyes and recuperate?"

"I don't know, Li Fan must be thinking!"

", I know I'm thinking, but how do you think about it?"

The audience looked at Li Fan, who was still motionless on the stage, with huge questions, and no one could guess what kind of "logical movement" was going on in Li Fan's brain at this moment.

Under the close-up shot, Li Fan frowned, breathed evenly, and stood quietly with a straight figure.

And in his mind, the data is being grouped together:

The first face on the lower left side of the polyhedral planar expansion diagram can be numbered 36, 98, 75, 209. 319, or numbered 75 or 319.

No. 36 pattern, numerical information: 1.

No. 98 pattern, numerical information: 3.

No. 75 pattern, numerical information: 5.

……

No. 319 pattern, numerical information: 2.

In the first combination, the numbers on the numbers 36 and 98 are added together, 1+3=4.

In the second combination, the sum of the numbers is 8.

In the third combination, the sum of the numbers is 7.

Therefore, it can be seen that among the three combinations that make up the first surface on the lower left side of the polyhedral planar map, the first combination has the lowest sum of numbers and is the optimal solution. This face should be made up of patterns No. 36 and 98!

Polyhedral plane unfolding diagram, among the 34 faces, one of the faces is solved, and Li Fan thinks about it in 3 seconds.

By analogy, the optimal solution of the second surface of the plane expansion diagram is pattern No. 8, 16, and 360, and the sum of the numbers is 6;

On the third surface of the plane expansion diagram, the optimal solution is pattern No. 99 and 283, and the sum of the numbers is 5;

……

2 minutes later, Li Fan suddenly opened his eyes, and his calm gaze was sharp, and the audience who was familiar with the show knew that the game was over.

Turning around suddenly, Li Fan picked up the handbag at his feet, and re-entered the prop room, he raised his arm high, and quickly pulled down the target pattern above his head, No. 10, No. 15, No. 18...... The various patterns are thrown into the pocket in turn.

Without the slightest hesitation, Li Fan's hands were fast, and from one side to the other, a total of 75 patterns were taken off, and it took 1 minute.

Li Fan glanced down at the handbag, Qi Huo!

Lin Xiaofeng, who was busy sweating in her prop room, when she saw that Li Fan had left the prop house, she knew in an instant that she was going to lose.

Her opponent is none other than Li Fan! Li Fan has always been a perfect performance of zero mistakes and a success on this stage, and she has faintly realized that Li Fan will not return to the prop room to re-observe.

The panicked Lin Xiaofeng hurriedly controlled herself not to think about it, she immediately threw herself into the game, and reached out to try to reach down a pattern, but the pattern hung a little high, and she didn't reach it, so she jumped a little, but still couldn't reach it.

Lin Xiaofeng hurriedly ran outside and picked up the auxiliary rod, but when she turned around, she saw Li Fan standing in front of her.

Li Fan handed her the No. 99 pattern that he had just taken off for her by the way, and then patted her on the shoulder, "Yours." ”

His gaze was calm and calm, his face was as good as a crown of jade, and there was a smile on the corner of his mouth, which was still harmless to humans and animals.

But Lin Xiaofeng, at this moment, has been completely defeated by this smile.

Li Fan nodded, said "come on", and walked quickly to the challenge area.

There are two tables in the challenge area, which are Li Fan and Lin Xiaofeng's, Li Fan came to his table, reached out and took out a pattern from his handbag at random, adjusted the orientation angle, and put it on the upper side of the table.

After that, he took out another random pattern, frowned slightly, and after estimating the position and angle, he placed it in the lower left corner of the table.

The third piece was still randomly taken out of the bag, and when it reached the middle of the table, the fourth piece was placed in the lower right corner!

……

At first, everyone in the recording hall was unaware of Li Fan's intentions, but when Li Fan placed one-third of the pattern on the table, some people suddenly realized!

Yao Qian was the first to exclaim: "Wow, I really figured it out!"

Guo Ming suddenly slapped his thigh, Huo Di got up, held his head in his hands and looked at Yao Qian and said, "Li Fan is too good, I understand, super god!"

Sun Feifei didn't turn a corner, and asked suspiciously, "What's wrong?"

Guo Ming couldn't wait to share: "You see, the pattern that Li Fan took out of his handbag was random, right? However, he definitely didn't put it on the table randomly, but it was 'organized and premeditated'!"

"Huh?"

Guo Ming was very excited, "You haven't understood it yet?" You see, the pattern that Li Fan put on the table has not been touched since it was put away, and at first, the east and west were not close to each other, and they were independent and unrelated.

However, as the number of patterns placed on the table gradually increased, some of the patterns have closed with each other. ”

Sun Feifei: "Ah, what do you mean?"

Guo Ming interrupted, and then said: "Yes, I mean, Li Fan has already virtually sketched the positions of each side of the plane expansion diagram on the desktop, and what he is doing now is to take out the patterns in the handbag one by one and put them in the approximate position that he has virtualized.

In other words, he doesn't think about the assembly of a single face at all, just like setting up a chessboard, if he gets the 'cannon', he puts it in the position of the 'gun', and when he gets the 'rook', he puts it in the position of the 'rook'!"

Guo Ming just finished the analysis, and basically all the audience at the scene also studied and understood, because Li Fan had already put two-thirds of the pattern on the table, and the entire plane expansion diagram had been basically formed, and it was about to come out!

The audience was dumbfounded.

"Wow!"

"Oh my God, can you still do this?"

"I'm a god!"

……

With the last piece of pattern placed on the table, the planar unfolding of the polyhedron is complete!

After Li Fan put the slightly loose overall figure together, he said, "I'm done, please verify!"

Doctor Chen "Huo" got up and clapped his palms excitedly, "Whether it's right or wrong, this is a god-like operation, it's the first time I've seen someone do a puzzle like this!"

Li Fan, you are the strongest brain in China. ”

Jia Yun smiled: "I haven't verified whether it's right or wrong." ”

Doctor Chen said excitedly: "I said, whether it's right or wrong, this is a god-like operation!"
