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

When it picked up the polyhedral prop, after observing it all over, the entire polyhedral instantly spread out into a plan in his mind. The size of the 34 faces forming the polyhedral, the angle between the sides, the angle orientation, etc. are all clearly transformed into imprints.

In just 10 seconds, Li Fan threw down the polyhedral props and walked quickly to the prop house behind him. In this short moment, Lin Xiaofeng was scared and the audience in the room was shocked!

Too fast, after all, too fast!

What does it mean in 10 seconds? Li Fan seemed to just take a look and just glance at it, then threw the props away and lived!

This is very simple for Li Fan. Compared with the previous project [Cantonese Origami], the derivation of origami works based on vertices is easy.

But it is too difficult for the audience, too shocking and incredible!

"Wow, it was so handsome when I threw down my props!"

"Clean and coquettish!"

"Li Fan is awesome!"

...

Guo Ming asked uncertainly: "Have Li Fan really figured out the plan expansion diagram?"

Doctor Chen analyzed: "Yes, it should be true. With my understanding of Li Fan, this level of spatial ability test has basically no obstacles to him. Our focus is on the back. The part of the assembly of plane expansion diagrams is the most difficult!"

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

Doctor Chen said: "This is completely impossible to give a specific time. You think, the plane expansion diagram of props is composed of at least 30 surfaces, and each surface can be composed of patterns in the prop house in different combinations.

Therefore, there may be countless combinations of correct answers to players who make up a plan expansion diagram. Any combination can pass the level and hand it over to their teammates for the next round of challenges!”

Sun Feifei said: "Oh, although there are many 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 will never know whether his combination method is the optimal solution!

Unless he can find all the answers!"

Sun Feifei shook her head violently, "How is it possible? It's a fairy tale!"

The eyes of several guests and teachers all gathered on Li Fan's back. 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 carefully, his eyes lingering in various patterns hanging under the roof, and then took a light step and walked gracefully.

Countless graphic information crashed into his eyes and quickly filtered in his mind. When he walked from one side of the dollhouse to the other, his mind had firmly locked the positions of 198 patterns. These 198 patterns are all the "components" that can form a plane expansion diagram.

From one side to the other side, the width of 3 meters, the length of 5 meters, and 400 patterns, Li Fan completed the first round of observation in just 2 minutes.

The exclamation sounded again in the recording hall! Scanning, another typical "Li Fan's scan"!

Li Fan took a deep breath. The first time he had just observed, he had completed the observation of the pattern shape, but this was far from enough. This was the first step in the Long March!

Each hanging pattern has numbers and numbers, and the numbers on the pattern are 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 interfering patterns during the second round of observation, and started directly from the effective patterns, which greatly improved efficiency.

He walked and stopped, constantly looking at the digital information on the pattern above his head. When he had just taken two small steps, Lin Xiaofeng's figure appeared in the ostentatious light.

Lin Xiaofeng also completed the observation of polyhedron at this time and just ran into his doll house.

Li Fan didn't expect Lin Xiaofeng to be quite fast. He calmed down and continued to observe himself.

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

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

Li Fan closed his eyes again!

It’s dark in Lin Xiaofeng!

A very interesting scene appeared on the stage. Li Fan, Jing like a "virgin", stood there and entered his own world, while Lin Xiaofeng was moving like a rabbit, and she was also a rabbit with carrots snatched.

She ran around the doll house in panic, hurriedly pulling the pattern down from the roof, constantly trying to piece together the pattern, but constantly failing.

"It's over, that girl is panicked!"

"Go calm, girl, don't worry!"

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

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

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

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

In the close-up, Li Fan frowned, breathed well, and stood quietly with a straight figure.

In his mind, the data is being combined in categories:

The first surface on the lower left side of the polyhedral plane expansion diagram can be composed of three methods: number 36, 98, number 75, 209.319, or number 75, 319.

Number 36 pattern, digital information: 1.

No. 98 pattern, digital information: 3.

No. 75 pattern, digital information: 5.

...

No. 319 pattern, digital information: 2.

The first combination method is to add the numbers on the pattern number 36 and 98, 13=4.

The second combination method, the sum of the numbers is 8.

The third combination method, the sum of the numbers is 7.

Therefore, it can be seen that among the three combination methods that constitute the first surface on the lower left side of the polyhedral plane expansion diagram, the sum of the numbers of the first combination method is the lowest, which is the optimal solution. This surface should be composed of patterns No. 36 and 98!

The polyhedral plane expansion diagram, one of the 34 surfaces is solved, and it took Li Fan 3 seconds to think about it.

And so on, the second face of the plane expansion diagram is the optimal solution to the pattern No. 8, 16, 360, and the sum of the numbers is 6;

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

...

Two minutes later, Li Fan suddenly opened his eyes, and his calm eyes were sharp. The audience familiar with the show knew that the competition was over.

Saran turned around, Li Fan picked up the handbag at his feet and stepped back into the doll room. He raised his arm high and quickly pulled down the target pattern above his head, No. 10, No. 15, No. 18... Various patterns were thrown into the handbag in turn.

Without a trace of hesitation, Li Fan's hand speed was fast, and a total of 75 patterns were taken off from one side to the other, which took 1 minute.

Li Fan looked down at his handbag, and he worked together!

Lin Xiaofeng, who was busy in her dot house, was sweating all over her head. When she saw Li Fan had left the dot house, she knew in an instant that she would definitely lose.

Her opponent is not someone else, that is Li Fan! Li Fan has always been a perfect performance of zero mistakes and one success on this stage. She has already vaguely realized that Li Fan will not return to the doll house to observe again.

Lin Xiaofeng was panicked and quickly controlled herself not to think too much. She immediately joined the competition and reached out to try to get a pattern, but the pattern was hanging a little high and she didn't reach it, so she jumped for a moment, but it still didn't reach it.

Lin Xiaofeng hurriedly ran outside and picked up the auxiliary pole, 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, and then patted her on the shoulder, "Your."

His eyes were calm and calm, his face was as good as ever, and his smile spreading around his mouth was still harmless.

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

Li Fan nodded, said "Come on", and quickly walked towards the challenge area.

There are two tables in the challenge area, namely Li Fan and Lin Xiaofeng. Before Li Fan came to his desk, he reached out and took out a pattern from his handbag casually, adjusted the angle, and placed it on the upper side of the table.

Afterwards, he took out a random pattern, frowned slightly, estimated the position and angle, and placed it in the lower left corner of the table.

The third pattern was still taken out of the handbag randomly. 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 did not realize Li Fan's intention of this move. When Li Fan placed one-third of the pattern on the table, some people suddenly realized it!

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

Guo Ming suddenly slapped his thighs, stood up suddenly, hugged his head with both hands and looked straight at Yao Qian, "Li Fan is so awesome, I understand, super amazing!"

Sun Feifei didn't turn around and asked in confusion: "What's wrong?"

Guo Ming couldn't wait to share: "Look, it was random for Li Fan to take out the pattern from his handbag, right? But he definitely did not put it on the table randomly, but was 'organized and premeditated'!"

"ah?"

Guo Ming was extremely excited, "I haven't understood it yet? Look, the pattern Li Fan placed on the table has never been moved after putting it in. At first, it was not touched by the land in the east and west, and each one was independent and had no connection.

But as the patterns placed on the desktop gradually increase, some of them have been closed to each other."

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

Guo Ming interrupted and continued: "Yes, I mean, Li Fan has virtually outlined the positions of each surface of the plane expansion diagram on the desktop. What he has done now is just taking out the patterns in his handbags in sequence and putting them in the rough position he virtually showed.

In other words, he didn't consider the single-sided grouping at all, just like putting on a chessboard. When he got the "cannon", he put the "cannon" position, and when he got the "car" position, he put the "car" position!"

After Guo Minggang finished analyzing, basically all the audiences on the scene also understood, because Li Fan had put 2-3 of the pattern on the table, and the entire plane expansion diagram had basically taken shape and was about to come out!
