"How is that possible, how can there be such an algorithm?"

The old man in sackcloth seemed to react, his face was full of disbelief, and he hissed: "The old man has been instructed by his master, and he has been studying arithmetic for decades, and he has never been secret, and this question has been deduced hundreds of times, but it was easily solved by you, what is the reason?"

"Ridiculous!"

Yi Tian seemed to have heard some joke, and said with disdain: "It's just binary arithmetic, you actually regard it as a treasure, do you know that there are ternary or even multivariate operations in the world?"

Speaking of this, his voice paused, and he snorted coldly: "Also, the Nine Palaces diagram that you are playing tricks with is just a child's trick, can you solve the sixteenth palace?"

"This ......"

The old man in sackcloth was like five thunderbolts, and he only felt that his brain was rumbling, and what he was usually smug about was actually said to be so unbearable by this young man. Pen, fun, pavilion www. biquge。 info

Could it be that during the ten years of his seclusion in Taiyuemen, the outside has been turned upside down, and the things he has painstakingly studied are really regarded as daily games by children?

"By the way, you should be called Liang Yan, the fourth disciple of Master Zhou, right?"

While speaking, Yi Tian stepped forward and sat on the bench, as if he was the owner of this room, but at this time, he suddenly found that there was another item on the long table, which looked extremely familiar.

It was a wooden object, a boxy shape, divided into six sides and six colors, with a total of more than 100 square prism-shaped wooden blocks, which were connected to form a whole.

Rubik's Cube?

Yi Tian was a little surprised and reached over, then grabbed the thing in his hand, and sure enough, he found that it could be rotated, but it was not the Rubik's Cube he had played with when he was a child.

This is not only a Rubik's Cube, but also a sixth-order Rubik's Cube, which is relatively difficult to play.

"Liang Yan, you usually play this?"

The old man in sackcloth was that Liang Yan, he was originally said to be like ashes, but when he saw Yi Tian fiddling with the wooden square, his face seemed to be rejuvenated, but he immediately said: "This is called Liutong, it is indeed a gadget that the old man usually plays, completely disrupting the color on it, and then restoring it into a whole in the shortest time." ”

As he spoke, he stretched out a hand, which he obviously intended to demonstrate.

"Good!"

Yi Tian's face was full of interest, and he threw the six links in his hand over, in fact, this thing is the Rubik's Cube, but it was named Liutong by Liang Yan, but it depends on how he plays?

Sure enough, just like playing a Rubik's Cube, Liang Yan grabbed the six tongs in his hand, and twisted his hands indiscriminately, completely disrupting the colors on it.

"The old man often plays with these six links, and it only takes a quarter of an hour to completely fiddle with it. ”

As Liang Yan spoke, he took out the hourglass on the long table, shook it slightly in his hand, completely reset the time inside to zero, and placed it next to the oil lamp.

"Look, the timer begins!"

As soon as the words fell, Liang Yan immediately became engrossed, he grabbed the Rubik's Cube with both hands, and his ten fingers continued to swing rapidly, like a butterfly wearing flowers, only to hear the sound of clicking, which was simply unspeakably fast.

To play the Rubik's Cube, not only the speed of the hand is high, but also contains the rules of operation, if you do not carefully figure it out, I am afraid that it will not be able to do it in a short time, and beginners often have to give up.

That Liang Yan is obviously a master of calculation, he is constantly deducing the process in his mind, but his two hands are like Tai Chi pushing hands, as if they are rotating the five elements of yin and yang, containing some kind of peculiar law.

The sixth-order Rubik's Cube is composed of more than 100 small pieces, completely disrupting the color, and then restoring the same, it is indeed not so easy, if ordinary people sit here, I am afraid that there will be no results for three days and three nights.

"It's done!"

Within a moment, he only heard Liang Yan chuckle, and the magic in his hand rotated twice, and he placed it in the middle of the long table, and sure enough, the six colors were neat and orderly, completely distributed on six sides, and there was no confusion at all.

At this time, the time displayed on the hourglass was exactly a quarter of an hour.

"How?"

Liang Yan's expression was a little arrogant, and he said with a smug face: "Although this Liutong is a gadget, it contains complex calculations, if it weren't for the old man's dedication to studying the principles, it would definitely not be so fast?"

"Really?"

Yi Tian seemed to be a little unconvinced, but he turned his head to look at Gu Chengcai, and said with a smile on his face: "Chengcai, do you want to try it?"

"Okay, City Lord!"

Gu Chengcai also really had itchy hands, so at this time, he stepped forward and reached out to grab the thing.

"Young man, don't be reckless!"

Liang Yan grabbed Liutong in his hand first, but looked at Gu Chengcai with hesitation, especially the empty right sleeve, and couldn't help frowning: "You only have one hand, but how do you play Liutong?"

At this time, he didn't look down on it, if you want to play the Rubik's Cube, it is really difficult to use one hand, if you spin faster, won't it fall off?

"For me, one hand is enough!"

Gu Chengcai's tone was categorical, it seemed to be unquestionable, but in Liang Yan's ears, he didn't believe it at all, even if you were talented, you couldn't be so arrogant.

"Young people, excessive self-confidence is arrogance. ”

While speaking, Liang Yan shuffled the Rubik's Cube in his hand and put it in front of Gu Chengcai, but it was up to him to see what tricks he could use with one hand?

"Please excuse me, help me time!"

Gu Chengcai stretched out his right hand, threw the Rubik's Cube twice in his hand, and put it under his eyes to observe it carefully, as if he was cracking the law.

"Let's go!"

Liang Yan had a sneering look on his face, turned the hourglass completely upside down, and reset the time, he wanted to take a look, how did this yellow-mouthed kid humiliate himself?

But soon, the look of disdain on his face gradually became a little sluggish, and finally turned into a complete shock, with an incomprehensible look on his face.

Although there is only one hand, Gu Chengcai's hand speed is also full, the five fingers are as flexible as a swimming snake, the speed is so fast that it is difficult to see with the naked eye, and the Rubik's Cube is like detaching from the fingers, and it can only be seen constantly rotating.

This made Yi Tian also unexpected, but when he turned his mind and thought about it, he could completely understand, just like a blind man's sensitive hearing, although Gu Chengcai lost his left arm, many things need one hand to complete, so he also exercised his right hand, of course, it was several times more flexible than ordinary people.

"That's it!"

As he spoke, the magic machine flew out and landed lightly on the long table, the colors on which were neat and orderly, apparently completely restored.

"So fast?"

For the first time, Liang Yan turned his head to look at the hourglass next to him, and immediately had an incredible look on his face, but he saw that the time that had passed on it was only half an hour.

How can it be?

Half an hour, and with only one hand?

This is too wicked, how the hell did he do it?
