"Look!"

I saw Fang Lian searching in the bag for a while, and took out an emerald green wrench from it...

Oh! It's an emerald green ring.

Cheng Nuo looked up and looked at Fang Lian in confusion, "Sister Fang, is this..."

"Here you see, which dynasty is this ring produced?" Fang Lian asked with a smile to Cheng Nuo.

"Well..." Cheng Nuo smashed his mouth, and his eyes swept the jade ring in Fang Lian's hand.

Weighing 21.14 grams, height 2.6 cm, diameter 3.3 cm, pore diameter 2 cm, produced in 1402.

"Why, can't you tell me?" Fang Lian couldn't help but ask when he saw Cheng Nuo's hesitation look.

"Not that." Cheng Nuo smiled faintly, "but I have a condition."

Fang Lian looked at Cheng Nuo charmingly with a pair of peach blossom eyes, curled his lips slightly, "Are you planning to let me agree with me?"

Cheng Nuo sweated heavily, twitched the corners of his mouth and said, "No, no. Sister Fang, you just need not tell my parents what happened today."

"Don't worry, I'm not a big mouthful." Fang Lian nodded, "But then, I didn't expect you to be a virgin brother?"

Fang Lian covered her mouth and chuckled.

"Okay." Fang Lian suddenly became serious and said to Cheng Nuo, "Cheng Nuo, can you tell me now which dynasty this ring is produced by?"

Cheng Nuo nodded, "If I guess correctly, it should have been produced in the Ming Dynasty."

"Ming Dynasty?" Fang Lian's eyes flashed slightly, not knowing what he was thinking. However, his face was not very good-looking.

"Yes." Cheng Nuo nodded slightly.

Fang Lian pondered for four or five seconds before continuing to say to Cheng Nuo, "By the way, when will you get to Qingcheng?"

"It'll be about a week later." Cheng Nuo said after evaluating the recording time of the most powerful brain.

Fang Lian nodded and waved to Cheng Nuo, "That's it, I have something to do, Bye~~"

Fang Lian came and left in a hurry, which made Cheng Nuo a little confused and didn't understand what the year Fang Lian asked herself was for.

Cheng Nuo scratched his head, took a taxi and returned to the hotel.

…………

In the next few days, Cheng Nuo's life went on in an orderly manner according to the established trajectory.

The most powerful 1V1 knockout stage will also start recording in two days.

Since Cheng Nuo is the 8th group contestant, the recording time is on the third day after the recording begins.

He and Li Shiye, and two other groups of players who participated in the PK will have a desperate battle that day.

…………

Time came to the day when Cheng Nuo participated in the recording of the program in the blink of an eye.

The program recording time starts at 10 a.m. and the end time is uncertain.

Because of different challenges, the time required is different.

Yesterday, there was a challenge of memory + observation. The memory time was only two or three hours. After recording the entire three games, it was already late at night.

The six contestants participating in the program were all arranged to rest in the program's backstage lounge.

They will not play when it is their turn to play.

"God, I want to cheer up today!" Ying Yingying held her little hand tightly and cheered Cheng Nuo.

It is worth mentioning that Ying Yingying and another girl got the No. 9 lottery.

This means that the two participated in the same batch of recordings. After Cheng Nuo and Li Shiye's PK ended, there was a showdown between Ying Yingying and another girl.

In addition to these two groups, the seventh group is two boys. One comes from Tsinghua University and the other comes from Peking University! It can be said to be a strong showdown!

Nine-fivety.

The staff came to the lounge and called the two people in the seventh group away. At the same time, they asked Cheng Nuo and Li Shiye to prepare.

Cheng Nuo and Li Shiye looked at each other, snorted coldly, and ignored each other.

Genius is arrogant and withdrawn.

Li Shiye is such a person. He is born aloof, cold-hearted, unwilling to communicate with others. This is also the reason why he has always worn black clothes.

Black, it is easy to hide yourself.

There is a display screen in the lounge where all the pictures of the recording site can be transmitted to the display screen, so that the contestants who are about to compete can see the recording site.

At 10:00 am, with the voice of the director, the recording of the third game of the 1V1 knockout match of the fifth season of "The Brain" officially began.

Teacher Jiang walked out with passionate music.

After reading the opening remarks and introducing several guests, Teacher Jiang invited the first group of contestants to appear.

The two, one is Zhang Zheng from Tsinghua University, and the other is Sun Meng from Peking University!

Peking University VS Tsinghua University!

The fierce showdown between two top universities and top students begins soon!

During the 1V1 challenge stage, there are audiences watching it.

There were almost four or five hundred spectators sitting in the entire audience.

When the audience heard the origins of Zhang Zheng and Sun Meng, the atmosphere instantly became boiling.

The match between Tsinghua students and Peking University students is full of highlights!

I just don’t know what project they are challenging?

The host invited the two of them to his side. After the two of them made them say something harsh to each other for the sake of the program effect, the competition officially began!

The name of the two-person challenge project is:

Three-dimensional one stroke!

On the stage, there are a total of 200 irregular three-dimensional polygons placed in it.

What the two contestants need to do is to find a three-dimensional polygon that can start from the point on the three-dimensional polygon, without repeating a stroke, passing through each edge.

In a total of five minutes, find the right one and add one point. Find the wrong one and deduct two points in reverse!

After the time is over, whoever scores more will win!

The rules of this challenge project are not difficult to understand.

Simply put, it is to upgrade the plane stroke problem we usually see, and transform it from plane to three-dimensional.

A three-dimensional polygon consists of three parts: points, lines and surfaces. Drawing a three-dimensional polygon in one stroke means connecting all points with several unrepeating lines to form a three-dimensional polygonal surface.

The program team gave 200 three-dimensional polygons, all of which were irregular in shape.

Naturally, the number of points, lines and surfaces is also different.

This undoubtedly caused great trouble for the players to solve the problem.

At the recording site, amid the audience's nervous expectations, the competition between the two top Chinese universities officially began.

Both players walked into the challenge position with nervous expressions, filtering each of the 200 irregular three-dimensional polygons at a speed of more than ten seconds.

Backstage lounge.

All four of them were passing through the screen and watching the movements of the two contestants on the stage.

"God, how do you think this project is difficult?" Ying Yingying turned her head and asked curiously, "The difficulty coefficient of the projects that can make them challenge Tsinghua University and Peking University must be quite large, right?"

In Ying Yingying's view, there are so many irregular three-dimensional polygons on the field. To determine whether a three-dimensional polygon can be drawn in one stroke, the contestant must use his spatial imagination to choose any point as the starting point, and try whether he can write it in one stroke. If he can't, choose another point as the starting point and try again.

Until you try all the points on the three-dimensional polygon as the starting point and find that you can't finish it in one stroke, you can't confirm that the figure cannot be drawn in one stroke!

"The difficulty coefficient is 9 points." Cheng Nuo answered casually.

Just when Ying Yingying was surprised at the difficulty of this question, she heard Cheng Nuo continue to add, "The full score is 100 points."

Ying Yingying: “…”

Master, are you kidding?

Cheng Nuo smiled faintly and said to Yingying, "Have you heard of the seven bridges of Ora?"
Chapter completed!
