Chapter 129

The statement also naturally noticed that Cheng Nuo was looking at himself.

He throws the Rubik's cube into the air and firmly receives it in his hand. He is proud to pick up Cheng Nuo's eyebrows.

"Can you play Rubik's cube?"

Cheng Nuo a smile, "can a bit."

Cheng Nuo was really obsessed with Rubik's cube for a while.

From the second level to the seventh level of Rubik's cube can play a little.

However, the level is only limited to be able to restore according to the online tutorial.

As for speed

Cheng Nuo remembers that the fastest recovery speed of his third level Rubik's cube seems to be more than 30 seconds, and the gap between him and the real Rubik's cube master is not too big.

There was an imperceptible joy in the statement's eyes, and he said casually, "Cheng Nuo, since we are all the top 200 players with the strongest brains, we are not as good as How about a comparison? "

"Compared with Rubik's cube, I won't take advantage of you. You use both hands, I use one. How about it? "

Statement looks forward to looking at Cheng Nuo.

"Not so much." Cheng Nuo holds his arm and continues to find a comfortable position to lean on the back of the chair.

Statement is obviously bullying Cheng Nuo, do not understand the market.

Although the third-order single handed is more troublesome than the third-order speed twisting, the speed of the third-order single handed is about 3-4 seconds slower than that of the third-order speed twisting.

Take the Rubik's cube records in China as an example.

The third-order speed is 5.19 seconds, and the third-order single hand is 8.27 seconds.

Both records were created by the same person.

With Cheng Nuona's slag speed of 30 seconds, he will not be hanged by one handed statement.

"Come on, come on, Cheng Nuo. The plane is so boring. Do you want to play?" It's hard to pretend to be an opportunity. I feel that I must grasp it.

"No!" Cheng Nuo don't overdo, extremely arrogant Jiao said.

"A meal!" The statement pointed up a finger and said, "as long as you win, I'll have dinner for both of you tonight. I'll take whatever you want."

"Good, deal!" Cheng Nuo grins innocuously.

A white meal, you must hold it!

"But..." Cheng Nuo's voice suddenly changed. "We don't play third-order! The third order is too simple to be interesting. "

Statement a face of self-confidence, "then you want to play a few steps, I'll be ready to accompany."

"What's the highest rank you have now?"

"Seven steps." After searching from his backpack for a while, he took out a seven order cube which was several sizes larger than the third order cube.

The seventh order magic cube is composed of 218 blocks. Due to the geometric constraints, the surface is circular. Prices vary from more than 100 yuan to more than 1000 yuan.

The total number of changes is 1.95 * 10 ^ 160.

Cheng Nuo a face does not matter, "then we compare seven order."

"It won't work." Statement shakes his head, "seven order Rubik's cube, I can't play with one hand."

Don't say it's a statement. Even if we call the world's top Rubik's cube gods, we can't restore the seventh order Rubik's cube with one hand.

Because

This thing is so big!

One hand can only barely hold, restore is not to think about.

"I'm not asking you to restore it with one hand. Both of us use our hands to see who can restore faster. " Cheng Nuo shrugs.

"Sure?"

"Sure, and sure."

"Who will come first?"

"You come first. I'll brew it first."

The statement handed Cheng Nuo the Rubik's cube. "OK, I'll go first. You'll mess up the Rubik's cube."

"I will, I will..." Jiang Jun, who had been watching all this, stopped the Rubik's cube from mid air, brushed it a few times, and then disrupted it.

Six sides, yellow, white, blue, green, red and orange, six colors, a total of 218 squares, completely disordered into a trace of irregular appearance.

Time, go!

Cheng Nuo opens the stopwatch on his mobile phone and starts timing.

As the champion of the seventh stage quick twist in last year's University Rubik's cube open, the strength is certainly not covered.

As soon as Rubik's cube was started, he took about a second or two to look at the six faces first.

Then he lowered his head and his slender fingers danced on the cube.

Creak creak Rubik's cube spin sound in Cheng Nuo ear next to ring.

The reduction formula of the seventh order Rubik's cube is very complex, and the fourth and fifth order Rubik's cube reduction formula is also needed, which requires high brain speed of statement.

When playing the third order Rubik's cube, the hand speed can't keep up with the brain speed.

And when it comes to the seventh order cube, the brain speed can't keep up with the hand speed.

This is a common phenomenon for all Rubik's cube players.

Cheng Nuo saw the number on the stopwatch beating.

30 seconds 60 seconds 90 seconds

Statement looks as usual, hands indefatigably continue to rotate Rubik's cube.However, every time, the statement should stop for about a second or two, to clarify his ideas, and then continue to restore the magic.

The seventh order magic square restoration, but a quite large and complex project!

"Call" -

after a few decades, the statement will take a breath and rotate the top layer clockwise by 270 degrees.

So far, the six sides of the seventh magic square are restored.

Time used 2 minutes 58 seconds 66.

"It's good." The statement saw the time and said with a smile.

The world record for the seventh order speed twist is 2 minutes, 06 seconds, 73.

The statement can reach 2 minutes and 58 seconds, which can be regarded as normal play.

The statement will restore the good magic side randomly twisted a few times, will be disordered, throw to cheno, "it's your time."

"Time it." Cheno opened slightly.

Time, start!

When the statement pressed the timer, cheno's eyes looked at the magic square in his hand, and a group of data flashed by.

The side is 7.75 cm long, 185.28 g in weight, 49 blocks on the first floor and the second floor There are 218 in total.

Number of yellow squares in layer R 5, position coordinates (1, 2) (5, 2)

Number of white squares in layer R

…………

L layer yellow square number 11, position coordinate

…………

In less than a second, cheno's eyes are like scanners, bringing all the data of this disrupted seventh-order magic cube into the brain.

Then, build the magic square model in your mind. Automatically calculate the restore scheme.

The first step is to rotate the U layer 90 degrees clockwise.

Second, the R layer rotates 270 degrees counter clockwise.

Step 3: B layer rotates 90 degrees counter clockwise.

…………

Step 56: the L-layer is rotated 90 degrees along the potential station.

…………

Why does cheno not choose and present the third-order Magic Party?

That's because cheno's hands don't keep up.

He has not trained specially. Even if the brain calculates the third-order magic cube reduction plan, the hand can not reach the speed, and it is inevitable to lose to the statement.

But the seventh magic side is different.

Brain speed is much more important than hand speed.

In the process of restoring the seventh magic cube, cheno doesn't have to worry about the problem of insufficient brain use.

All he needs to do is to restore at the fastest speed, according to the brain's calculated reduction steps.

In the statement of view, only see Cheng Nuo's hand speed is not fast, even for his such a magic master, such a hand speed is simply slow to crack!

But

What he can't believe is that, in the middle of the return, cheno has no Caton. It seems that the restoration process has been simulated in my mind.

"All right!"

When the statement is still in a daze, Cheng Nuo put the magic square in front of the statement.

Take a look at the statement.

Six faces, all restored!

"By the way, how long did it take me?" Cheng Nuo looks at the statement.

State that you look down and press the stopwatch for a pause. "Your time is..."
