Three times in a row.

He Youjun's mentality has changed from a small collapse before to a big collapse now.

As a result, he has been in an absent-minded state in the project of "Distinguishing Mountains at a Glance".

In the end, he finished 24th with a time of 15 minutes and 58 seconds.

And Li Lingxiao, the player who ranked third in the preliminary trial.

Since this event is not his forte, he only finished in 15th place.

Of the top three people in the preliminary examination, only Cheng Nuo is the only one, who still occupies the first place with his domineering and arrogant attitude. No one can shake it for the time being.

The godheads of He Youjun and Li Lingxiao began to look a little unstable in this round.

And Li Shiye, who was only ranked 11th in the initial ranking, had a strong momentum in these two rounds.

In the last "blind Sudoku" room, Li Shiye was the third player to complete the challenge after Cheng Nuo and Li Lingxiao.

And in this "Distinguish the Mountain at a Glance" room, Li Shiye became the second player to complete the challenge after Cheng Nuo with a score of 6 minutes and 57 seconds.

Its strong strength can be seen.

An hour later, the top 50 of "The Strongest Brain" were born!

Ying Yingying still advanced with a score of 49th.

The statement came in at 38th place in this round.

For example, Liu Xuxin, Ma Yiyi and other key objects of attention have also been successfully promoted.

............

Recording live.

At this point in the competition, the entire 100-seat seat was half empty. Empty acts abound.

Three of the top 10 have already been eliminated!

On the contrary, it is the bottom ten, and there are still five people left.

It can be seen that the preliminary ranking of the strongest brain, except for pretending, is really useless.

In order to let the remaining contestants be at the peak of their mental and physical strength when they challenged the last event, the program team let everyone rest for more than an hour before entering the recording of the last challenge.

This is also the last challenge of 100 into 30.

50 people, 20 people are eliminated, 30 people are left!

Those who can come to this point are all the pride of the sky, the dragon and the phoenix among the people.

No one wants to be eliminated in the last link.

So, everyone worked hard to fight for the hope of advancing in the last challenge!

"What will be the third round of challenges?"

"Look at the big screen!"

Everyone held their breath and stared at the big screen.

On the screen, the screen turns.

The four big characters of "topological origami" came into the eyes of everyone.

Topological origami, in simple terms, refers to a piece of origami that can be folded into four completely different patterns through two different origami methods.

Take the simplest face topological origami for example. The folding method is:

First, turn the A side of the origami paper towards you, pull the left and right corners cut in the middle, and fold it outward twice to get two complete faces.

Then face the B side of the origami to yourself, still holding the left and right corners cut in the middle to get two new complete faces.

In other words, a piece of origami has two different folding methods, and four different complete faces can be folded.

Of course, the project challenged by the contestants this time is naturally not the simplest face topological origami.

Because of the face topology origami, the feature points on the origami can be memorized by the player.

The size of the eyes, the position of the nose, the hairstyle...... And so on, these can become the memory points of the players.

Players don't even need to fold the topological origami in their minds, they just need to find the feature points they have locked on the topological origami!

As the program group of "The Strongest Brain", it is natural that it will not be limited to the most basic difficulty.

Therefore, the program team invited a team of experts to create a topic that can be called metamorphosis - QR code topological origami.

A QR code topological origami, after being folded in two different ways, four different QR codes will appear.

To put it simply, it is just a two-dimensional code that replaces the face of ordinary origami.

But the difficulty ...... But it's a geometric exponential increase!

The density and irregularity of black and white dots in the QR code will make it difficult for contestants to capture any effective feature points.

Coupled with the complexity of the QR code and the ever-changing distribution of black and white dots, there are extremely high requirements for the player's information capture ability.

At this time, it is somewhat impossible for the contestants to find the correct answer by relying on feature points alone.

They have to imagine in their minds the graphics of the QR code topology after folding the origami.

Then, using the way of global and local observation, lock in the accurate topological origami.

Moreover, the image for the player to observe is not a whole QR code generated after folding.

But...... One QR code, one-fifth part.

Only the central fifth of the QR code is visible to the contestants.

The challenge rule of this project is that the program team will give each contestant a QR code picture that covers four-fifths of the area.

After observing such a picture, the contestant needs to find what he needs in 500 pieces of QR code topological origami, and he can fold out the QR code picture in his hand, the origami!

500 pieces of topological origami, a total of 1,000 folds, 2,000 sets of similar QR code images.

The list goes on!

All the player needs to do is find the only answer.

The program team also seemed to know that this challenge was too difficult for the contestants, so each contestant was given three chances to challenge.

After an answer is entered unsuccessfully, the program team will give the contestant a new QR code picture. Continue his challenge.

However, in this case, once it fails, the new QR code image will consume a lot of observation and memory time. In terms of time, it will naturally be at a disadvantage.

............

The remaining fifty people, after understanding the rules of the game, were led by the staff to room three. That is, the "topological origami" room.

In the very center of the room, there is a rectangular workbench that can accommodate fifty people standing.

On the table, there is a number of 1~50. It's still a Xiaomi phone per person.

Around the room, the five hundred pieces of topographic origami were neatly arranged.

500 pieces of topological origami filled with QR code images put together. Dense black and white dots fill every corner of the origami.

It was no less shocking than the ten contour topographic maps of the previous room.

But after all, fifty people are players who have experienced strong winds and waves. After settling down a little, they walked to their respective positions, picked up their phones, and waited for the question to appear.

As in the previous round, the question of fifty people is not the same.

"Xiaomi mobile phones, born for fever, warm and not hot. ”

"Please turn on your mobile phones and get ready to receive the questions. ”

After forcibly inserting an advertisement, everyone's question immediately appeared on their mobile phone screens.

Cheng Nuo looked at the four-fifths area of the screen on his phone, revealing only the QR code picture of the middle one-fifth area, and frowned slightly.
