The statement naturally noticed that Cheng Nuo was looking at him.

He threw the Rubik's Cube in his hand into the air, took it firmly in his hand, and raised his eyebrows at Cheng Nuo proudly.

"Do you know how to play the Rubik's Cube?"

Cheng Nuo smiled, "A little." ”

Cheng Nuo has indeed been obsessed with the Rubik's Cube for a while.

From the second-order Rubik's Cube to the seventh-order Rubik's Cube, you will play a little.

However, the level is limited to being able to follow the online tutorial to restore.

And as for speed......

Cheng Nuo remembered that the fastest restoration speed of his third-order Rubik's Cube seemed to be more than 30 seconds, and the gap between him and the real Rubik's Cube master was not too big.

There was an imperceptible hint of joy in his eyes, and he said casually, "Cheng Nuo, since we are all in the top two hundred players with the strongest brains, we might as well ...... How about a comparison?"

"It's like a Rubik's Cube, and I don't take advantage of you. You use one hand, I use both hands. How?"

The statement looked at Cheng Nuo expectantly.

"Not very good. Cheng Nuo hugged his arms and continued to find a comfortable position to lean on the back of the chair.

The statement is obviously to bully Cheng Nuo for not understanding the market.

Although the third-order one-hand is much more troublesome than the third-order speed twisting, the real master, the speed of the third-order one-hand is at most about 3,4 seconds slower than the third-order speed twisting.

Take my country's Rubik's Cube record as an example.

The third-order speed twist is 5.19 seconds, and the third-order one-handed twist is 8.27 seconds.

Both records were created by the same person.

With Cheng Nuo's 30 seconds of slag speed, he will not be beaten by a one-handed statement.

"Come on, come on, Cheng Nuo, it's so boring on the plane, why are you having fun?"

"Don't come!" Cheng Nuo said with a very arrogant voice.

"One meal!" the statement raised a finger, "as long as you win, I will invite you two to dinner tonight, and I will invite you to eat whatever you want!"

"Okay, deal!" Cheng Nuo grinned, revealing a harmless smile from humans and animals.

A white meal, you must grasp it!

"But ......" Cheng Nuo's voice changed suddenly. "We don't play the third-order ones! the third-order ones are too simple and boring. ”

The statement looked confident, "Then if you want to play a few levels, I will accompany you at any time." ”

"Then what is the highest rank you are wearing now?"

"Seventh-order. After searching through his backpack for a while, he took out a seventh-order Rubik's cube that was a few sizes larger than the third-order Rubik's Cube.

The seventh-order Rubik's Cube, consisting of 218 squares, has an arc-shaped surface due to geometric limitations. The price varies from more than 100 yuan to more than 1,000 yuan.

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

Cheng Nuo had an indifferent expression on his face, "Then we will be better than the seventh-order." ”

"That's not going to work. The statement shook his head, "Seventh-order Rubik's Cube, I can't play it with one hand." ”

Not to mention a statement, even if you call those top Rubik's Cube gods in the world, you can't restore the seventh-order Rubik's Cube with one hand.

Because......

It's so big!

I can only barely hold it with one hand, and I don't have to think about it.

"I'm not asking you to restore it with one hand. We both use both hands to see who can restore faster. Cheng Nuo shrugged.

"Are you sure?"

"Sure, and sure. ”

"And who's going to come first?"

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

The statement handed the Rubik's Cube to Cheng Nuo, "Okay, I'll come first, you can mess up the Rubik's Cube." ”

"I'll come, I'll come ......" Jiang Jun, who had been watching all this from the side, unceremoniously intercepted the Rubik's Cube from mid-air, and after a few brushes, the Rubik's Cube was disrupted.

The six sides, yellow, white, blue, green, red, and orange, a total of 218 squares, were completely disrupted into the slightest irregularity.

Time, let's go!

Cheng Nuo turned on the stopwatch on his phone and started the timer.

As the champion of last year's College Student Rubik's Cube Open, the strength is certainly not covered.

As soon as he got his hands on the Rubik's Cube, it took him a second or two to look at the six sides first.

Then he lowered his head, and his slender fingers flew nimbly on the Rubik's Cube.

The sound of crunching and spinning the Rubik's Cube sounded next to Cheng Nuo's ears.

The reduction formula of the seventh-order Rubik's cube is very complicated, and it also needs to use the reduction formula of the fourth-order and fifth-order Rubik's cube, which requires a high brain speed for the statement.

When playing the third-order Rubik's Cube, the hand speed cannot keep up with the brain speed.

And when it comes to the seventh-order Rubik's Cube, the brain speed can't keep up with the hand speed.

This is a phenomenon common to all Rubik's Cube players.

Cheng Nuo saw that the numbers on the stopwatch were beating non-stop.

30 seconds...... 60 seconds...... 90 sec......

The statement looked as usual, and his hands tirelessly continued to spin the Rubik's Cube.

However, every once in a while, the statement has to stop for about a second or two to sort out your thoughts and then continue to restore the Rubik's Cube.

The restoration of the seventh-order Rubik's Cube is quite a huge and complex project!

"Whew-"

Tens of seconds later, the statement exhales lightly and rotates the top layer 270 degrees clockwise.

At this point, the six sides of the seventh-order Rubik's Cube have all been restored.

Unavailable...... 2:58.66.

"Not bad. Seeing this time, the statement said with a smile.

The world record for seventh-order speed twisting is 2:06.73.

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

The statement twisted the restored Rubik's Cube a few times, scrambled it, and threw it to Cheng Nuo, "It's your turn." ”

"Time. Cheng Nuo said lightly.

Time, let's go!

When the statement pressed the timer, Cheng Nuo's eyes looked at the Rubik's Cube in his hand, and groups of data flashed.

The side length is 7.75 cm, the weight is 185.28 grams, and the number of blocks is 49 in the first layer and ...... in the second layer 218 in total.

The number of yellow squares on the R floor is 5, and the position coordinates are (1,2)(5,2)......

Number of white squares in R layer......

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

The number of yellow squares on the L floor is 11, and the location coordinates are ......

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

In less than a second, Cheng Nuo's eyes were like scanners, gathering the data of this disrupted seventh-order Rubik's cube into his brain.

Then, build a Rubik's Cube model in your mind. The restore scheme is automatically calculated.

In the first step, the U-layer is rotated 90 degrees clockwise.

In the second step, the R layer is rotated 270 degrees counterclockwise.

In the third step, the B layer is rotated 90 degrees counterclockwise.

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

In the fifty-sixth step, the homeopathic station on the L floor rotates 90 degrees.

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

Why didn't Cheng Nuo choose and state the third-order Rubik's Cube of the competition?

That's because Cheng Nuo's hand speed can't keep up.

He has not been specially trained, even if the brain calculates the reduction scheme of the third-order Rubik's Cube, the hand speed cannot be reached, and it is inevitable that he will lose to the statement.

But the seventh-order Rubik's Cube is different.

Brain speed is far more important than hand speed.

In the process of restoring the seventh-order Rubik's Cube, Cheng Nuo didn't have to worry about the problem of not having enough brains at all.

All he needs to do is to follow the restoration steps calculated by his brain and restore them as quickly as possible.

In the sight of the statement, I saw that Cheng Nuo's hand speed was not fast, and even for a Rubik's Cube master like him, such a hand speed was simply slow!

Can......

What made him unbelievable was that in the middle of the restoration, Cheng Nuo did not have any stuck. It's as if I've already simulated the restoration process in my head.

"That's it!"

When the statement was still stunned, Cheng Nuo put the Rubik's Cube in front of the statement.

Statement a look.

Six faces, all restored!

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

The statement looked down at him as he pressed the pause stopwatch, "Your time is ......"

...... Coastline.........
