"Look!"

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

Ahh

Cheng Nuo raised his head and looked at Fang Lian suspiciously, "Sister Fang, ...... this?"

"Can you help me see, which dynasty produced this wrench?" Fang Lian asked with a smile at Cheng Nuo.

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

It weighs 21.14 grams, is 2.6 centimeters high, has a diameter of 3.3 centimeters and a bore diameter of 2 centimeters, and was produced in 1402.

"Why, can't you see it?" Fang Lian couldn't help but ask when he saw Cheng Nuo's hesitant look.

"Not really. Cheng Nuo smiled faintly, "It's just that I have one condition." ”

Fang Lian looked at Cheng Nuo seductively with a pair of peach blossom eyes, and hooked her lips slightly, "Are you going to let my sister and me make a promise?"

Cheng Nuo sweated profusely, twitched the corners of his mouth and said, "No, no." Sister Fang, as long as you don't tell my parents about today. ”

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

Fang Lian covered her mouth and chuckled.

"Alright. Fang Lian suddenly turned upset and said to Cheng Nuo, "Cheng Nuo, can you tell me which dynasty produced this wrench now?"

Cheng Nuo nodded, "If I'm not mistaken, it should be made in the Ming Dynasty." ”

"Ming Dynasty?" Fang Lian's eyes flashed slightly, not knowing what he was thinking. But the face is not good-looking.

"Hmm. 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 be able to meet Qingcheng?"

"About a week later. Cheng Nuo estimated the recording time of the strongest brain and said.

Fang Lian nodded and waved his hand at Cheng Nuo, "Then so be it, I still have something to do, Bye~~"

Fang Lian came in a hurry and left in a hurry, which made Cheng Nuo a little confused, and he didn't understand what Fang Lian asked him about the year of the jade wrench.

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

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

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

The 1V1 knockout stage of the strongest brain also began recording two days later.

Since Cheng Nuo is the 8th group of players, the recording time is on the third day after the recording starts.

He and Li Shiye, as well as two other groups of players participating in the PK, will compete to the death on that day.

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

time, in the blink of an eye, came to the day when Cheng Nuo participated in the recording of the show.

The recording time of the program is from 10 a.m. to an indefinite end time.

This is because the time required varies depending on the challenge.

Yesterday, there was a memory + observation challenge, and the memory time alone was two or three hours, and it was late at night after the entire three games were recorded.

The 6 contestants who participated in the show were all arranged to rest in the backstage lounge of the show.

They won't play until it's their turn.

"Great God, come on today!" Ying Yingying clenched her little hand and cheered Cheng Nuo on.

It is worth mentioning that Ying Yingying and another girl drew the No. 9 lot.

It also means that the two participated in the same batch of recordings, and after the PK between Cheng Nuo and Li Shiye, it was the showdown between Ying Yingying and another girl.

And in addition to these two groups, the seventh group is two boys. One is from Tsinghua University and the other is from Peking University!

Nine fifty a.m.

The staff came to the break room and called away the two people from the seventh group. At the same time, let Cheng Nuo and Li Shiye prepare.

Cheng Nuo and Li Shiye glanced at each other, each snorted coldly, and no one paid attention to anyone.

Genius is haughty and withdrawn.

Li Shiye is such a person, born arrogant, cold, unwilling and disdainful to communicate with others. That's why he's always dressed in black.

Black, easy to hide yourself.

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

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

Teacher Jiang walked out with passionate music.

After reading the opening remarks and introducing several guests, Mr. 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 will start immediately!

In the 1V1 challenge stage, there are spectators watching the scene.

There were about four or five hundred people sitting in the audience.

As soon as the audience heard the origin of Zhang Zheng and Sun Meng, the atmosphere instantly became boiling.

The showdown between Tsinghua students and Peking University students, this game can be described as full of highlights!

I just don't know, what project are the two of them challenging?

The host invited the two to his side, and for the sake of the show, after letting the two exchange some cruel words, the game officially began!

The name of the two-person challenge project is called:

Three-dimensional one-stroke painting!

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

What the two players need to do is to find a three-dimensional polygon that can start from a point on the three-dimensional polygon, without repeating it, and pass through each edge.

A total of five minutes, find the right one, add one point. Find the wrong one, and you will be deducted two points!

When the time is up, whoever has the most points wins!

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

To put it simply, it is to upgrade the flat one-stroke painting problem we usually see, from a flat to a three-dimensional.

A three-dimensional polygon composed of three parts: point, line, and surface. Drawing a three-dimensional polygon with one stroke refers to using several non-repeating lines to connect all the points to form the surface of the three-dimensional polygon.

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 a lot of trouble for the contestants to solve the problem.

At the recording site, in the nervous expectation of the audience, the competition between two top universities in China officially began.

The two contestants walked up to the challenge position with a nervous face, and among the 200 irregular three-dimensional polygons, they were sifting at a speed of more than ten seconds.

Backstage lounge.

The four of them are all through the screen, watching the every move of the two players on the stage.

"Great God, what do you think of the difficulty of such a project?" Ying Yingying turned her head and asked curiously, "The project that can make them Tsinghua University and Peking University challenge must be not small, right?"

In Ying Yingying's view, there are so many irregular three-dimensional polygons on the field, to judge whether a three-dimensional polygon can be drawn with one stroke, it is definitely necessary for the players to use spatial imagination in their minds, choose any point as the starting point, try to see if they can write it down, if not, choose another point as the starting point, and try again.

It is not until you try all the points on the three-dimensional polygon as the starting point that you find that you can't write it down with one stroke, and you can be sure that this figure can't be drawn in one stroke!

"It's a 9 out of 9. Cheng Nuo replied casually.

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

Ying Ying: "......"

Okami, are you kidding?

I saw Cheng Nuo smile faintly and say to Sakura, "Have you heard of Ora Seven Bridges?"
