Looking for and seeking, cold and lonely, miserable and miserable.

The two players of the island country, Ikawa Besan and Fuji Kei Eisho, are in such a mood right now.

I was pressed to the ground by an elementary school student and rubbed it......

That feels...... It's really quite sour!

Annuoyi won the fifteenth star, jumped up, returned to his challenge chair with a happy face, and said to Cheng Nuo as if inviting merit, "Big brother, I didn't hold you back!"

"Hmm. Cheng Nuo touched Anoyi's little head and praised, "You are the best!"

"Next, it's my showtime!"

After Cheng Nuo finished speaking, he straightened his clothes, got up, strode to the challenge platform, and said the type of difficult question he wanted to challenge in a smooth voice.

"Eight-digit plus minus mix for two seconds!"

Eight digits, six stars on difficulty!

Mix plus and minus, two stars on difficulty!

One second, 12 stars on difficulty!

Total difficulty, twenty stars!

Twenty stars for the highest difficulty!

Really......

When the Chinese audience saw the type of question Cheng Nuo chose, they all had such expressions.

Pretend to be a criminal, either don't choose, or, choose the most difficult!

The difficulty of the question type of 20 stars has been set up by the program team, and the question type with the highest number of difficult stars.

Originally, the purpose of setting this difficulty star topic by the program team was just to improve the quality of this challenge project.

As for the question type that will be chosen by this difficulty......

They never thought about it.

Because, the difficulty of this project is infinitely close to the limit of human beings.

In 1 second, 20 numbers appear, and on average, it is a number of 0.05 seconds.

The reaction time of the human eye is 0.042 seconds, that is, if the time for each number to appear is less than 0.042 seconds, all the numbers, in the eyes of the contestants, will become a continuous picture like a movie, rather than a frame-by-frame picture. It is almost impossible to tell whether a number is previous or next.

0.05 seconds is not yet the limit of 0.042 seconds, but it is quite close.

The effective digital capture time left for the contestants is only 0.008 seconds.

That's an eight-digit number.

An eight-digit number, whether you remember it or not, it takes 0.5~1 seconds just to read it from beginning to end.

And Cheng Nuo, you need to do it in 0.008 seconds!

Horror! Quite scary!

Some people who knew the difficulty of this question type, such as the two players from the island country, were already stupid on the spot, and looked at the figure standing in front of the challenge platform with dull eyes.

"It's fake, it's so hard, will anyone do it?"

This is the question of all island nation viewers at this time.

And the audience in China is sitting firmly in the Diaoyutai.

Whether anyone will make it, you will find out later!

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

"Cheng Nuo, are you ready?"

Teacher Jiang, who is well versed in Cheng Nuo's temperament, is too lazy to ask Cheng Nuo if he is sure of his choice. Directly asked Cheng Nuo if he was ready.

Cheng Nuo nodded, "Ready!"

"Alright, challenge, let's go!"

3！2！1！

20 eight-digit numbers, starting at a speed of 0.05 seconds, appear on the large screen in turn.

65451541！

-58794477！

+44222004！

......

16898728！

All the viewers felt that the numbers on the big screen were just flashing in their eyes.

And then......

And then there was no then.

They didn't even read the first two digits of an eight-digit number before jumping on to the next number. And then, it went on and on.

One second is a short time, which is the effort of blinking a few times.

The challenge is over before all the spectators think it's even started.

At this time, Cheng Nuo, who was standing in front of the challenge platform, had groups of numbers flowing in his eyes.

20 eight-digit numbers, at a speed comparable to that of a supercomputer, are rapidly adding and subtracting in his brain.

0.005 seconds later, Cheng Nuo had already come up with the answer to this set of lightning mental arithmetic.

65478774！

Almost without any hesitation, Cheng Nuo wrote down the number on the answer board.

Then, without hesitation, he turned around and signaled that he had finished answering.

As for the inspection?

Cheng Nuo has long said that as a top student, it is impossible to inspect, and it is impossible to inspect in this life!

Wow~~

Continue.

The audience was in an instant uproar.

Especially the audience in those island countries, looking at Cheng Nuo's eyes is like looking at a big demon king.

Just went down to a primary school student, and a big demon came up......

This makes us ...... How to play?!

"Good. Teacher Jiang asked the assistant to take Cheng Nuo's answer board in front of him, and asked Cheng Nuo with a smile, "Cheng Nuo, how confident are you in your answers?"

Cheng Nuo smiled faintly, "It's not high, it seems like I'm too crazy to say 100%." That's 101%. ”

Teacher Jiang was stunned by Cheng Nuo's answer for a moment, and then immediately reacted and said, "Haha, Cheng Nuo's medium meaning is good." ”

"Okay, without further ado, let's verify Cheng Nuo's answer right away!"

The large screen shows the correct answer.

"6! Correct!"

"5! Correct!"

......

"4! Correct !!"

"Congratulations to Cheng Nuo for completing the 20-star challenge!"

20 stars!!

The most difficult star!!

It can be said that in the next two rounds, as long as Cheng Nuo stabilizes his current level and does not make mistakes in his performance, he will enter the next stage, which is definitely a certainty!

It's the same with Anoy, who got 15 stars after the first round.

It is 6 stars higher than the lowest star value of Ikawa Belang.

There are still two rounds left, and Ikawa Beilang wants to chase these 6 stars back, which is almost impossible.

Perhaps the only thing that can be counted on is that Anoy made mistakes in the next two rounds in the later answering sessions.

Ikawa Belang and Fuji Hui Weisho, both of them had ugly faces.

Originally, they thought that with their strength, this was a sure win.

Unexpectedly, the two were first pressed to the ground and rubbed by a Lori elementary school student, and then completely abused by a big demon king.

"Let's take a look at the scores of the four players after the first round. Teacher Jiang said to the audience with a smile.

After the first round, the four players received the following stars:

Cheng Nuo, twenty stars!

Annoy, fifteen stars!

Fujihui Guard, eleven stars!

Farewell to Ikawa, nine stars!

Without any intermission, Cheng Nuo returned to the challenge chair, and the second round of challenges continued immediately!

With such a huge score behind, Ikawa had to give it a go.

So he frowned on the challenge platform, hesitated for a while, and then gritted his teeth and chose a five-digit question type that mixed with addition and subtraction for three seconds.

Total difficulty stars: 15 stars!

However......

Ikawa Belang still overestimated his strength.

The 15-star difficulty is obviously not something he can complete.

As a result, instead of getting 15 stars, 15 stars were deducted because of the wrong answer.

As a result, the star value of Ikawa Belang became a tragic -6 star.

All the Huaguo audience looked at the stage, the squatting on the ground with a skeptical expression on his face, Ikawa Beilang, and shook his head gently.

Poor child......

At this point, there is hardly any suspense in the following games.

Because even if Ikawa answered the 20-star question correctly in the third round, it was only 14 stars.

As long as Cheng Nuo and the three of them promise not to answer wrongly, they will be able to win.

And the result was indeed as everyone expected.

Fuji Hui Weisu obviously gave up on this unreliable teammate, and the remaining nine-star questions that both of them challenged were not low or low, and they scored 18 points steadily.

Cheng Nuo and An Nuoyi also chose a few stars at random to challenge the difficulty, and they were all successful.

At this point, the lightning mental arithmetic of the first stage of the mental arithmetic war has come to an end.

Ikawa don't wave, eliminate!
