"Kaka Kaka..."

Operation of the deformed metal ball, Richard roughly figured out the situation of the metal ball.

The first is the first form of the metal ball, that is, the ordinary metal ball, there is nothing special.However, once subjected to a strong impact from the outside world, it will become a second form, and an extremely terrifying and destructive breath will be issued to warn.

This warning is not plain and scary. Richard is very skeptical that if the external impact or the degree of destruction reaches a limit, the metal ball will explode devastatingly. The power index is seldom said to be thousands of T-level. It is the explosion of thousands of tons of TNT explosives, almost to the extent of a large ammunition depot.

At that time, the destructive power of the metal ball can easily destroy everything, not to mention the first-level wizard, even the second-level wizard or even the third-level wizard can't resist, the metal ball will be damaged in it, and even the slag is not left.

This design should be the manufacturer of the metal ball, in order to prevent the metal ball from being forcibly disassembled and destroyed, and prepared to ensure that the second form of the metal ball is opened by the person in a correct way.

As for the second form after the metal ball is activated...

"Kaka Kaka..."

Richard turned a few times at the changed metal ball again, his eyes narrowed, and he said to himself: "Cube."

Well, Rubik's Cube!

...

"Magic cube?" Pandora looked curious after listening to Richard.

"Magic cube? What is the cube? What is the cube?" The golden mask was also very puzzled.

After glancing at Pandora and the golden mask, Richard tried to explain: "The Rubik's Cube is the Rubik's Cube. You can use it as a toy or as a prop to exercise your mind, but the Rubik's Cube..."

Richard chatted, frowning gradually.

The second form of the metal ball in the hand is indeed a Rubik's Cube, a true Rubik's Cube, and there are different signs on the six sides-although there is no color division, each of them is depicted with long vertical lines, short horizontal lines, short left Slash, short right slash, left semicircle, right semicircle-the six elements that make up the Black Spirit Empire pattern.

This is a six-sided Rubik's Cube. The reason why it appears as a sphere is because it is a seventeenth order.

Yes, order seventeen!

The most common six-sided Rubik's cube is the third-order, that is, there are nine unit blocks with three sides and three sides on one side.Now, there are a total of 289 unit blocks in horizontal seventeen and vertical seventeen.In terms of the size of the fist, there are so many cells scattered all over the body, which makes the scalp numb.

As a result, if you twist it on this metal ball, the rotation is not a single-layer unit block. It may be a three-layer unit block or even a four-layer unit block. Only by twisting with a needle or nails can you be accurate enough.

In order to ensure that the dense unit blocks rotate smoothly, some of the corner unit blocks will be very close to the center ball of the Rubik's cube, the size will be slightly different, and some deformation treatment will be performed, and eventually a cube will become a near sphere.

Order 17!

Richard grabbed the deformed metal ball in his hand and felt heavy, but also heavy in his heart.

The Rubik's Cube was invented in 1974 on the modern earth by Erno Rubik, a professor at the Budapest School of Architecture in Hungary.

Let's not delve into how the Black Spirit Empire hundreds of years ago had such a thing, but it must be clear that it is difficult to restore the Rubik's Cube.

The restoration of the Rubik's Cube involves many mathematical principles.If a person is exposed to Rubik’s Cube for the first time, he is not proficient in any mathematical principles, does not know any tricks or tricks, and does not have a more prominent thinking ability, but just recovers by feeling, then it may be possible to spend days, weeks, or even months. .

This is not an exaggeration.

In fact, on the modern earth, the Guinness record of the third-order six-sided standard cube's slowest restoration was created by an Englishman named "Graham Parker".

After Graham Parker bought the Rubik's Cube in 1983 and first contacted it, it took about 26 years and a total of 27,000 hours to restore the Rubik's Cube that was disrupted by him.

This is still the simplest three-order six-sided standard cube. As the order increases, the difficulty of recovery will rise linearly.

Fourth order, fifth order, sixth order...

Now there are fifteen, sixteen, seventeen-a full seventeen steps!

Li Cha squeezed her lips and was not stunned by the 17th order Rubik's Cube.

He knows the mathematical principles involved in restoring the Rubik's Cube. He also understands some common methods of restoring the Rubik's Cube. Even if the current Rubik's Cube metamorphosis reaches the 17th order, he is confident to restore it.

In fact, let’s not say the seventeenth order, even the twenty-seventh order is no big deal—the record of the Rubik’s Cube created on modern earth is the thirty-third order—when the order of the Rubik’s Cube reaches a certain level, there is nothing special about continuing to increase Meaning, because it does not increase the difficulty of thinking in recovery, but simply increases the workload of recovery.

One of the most common ways to restore higher-order Rubik's Cube is the order reduction method.

Turn the Rubik's Cube first, so that the color center of each face of the Rubik's Cube is the same as before, restore the color center, and then match the unit blocks in the middle of each edge to perform the merge.

In this case, no matter how perverted the higher-order Rubik's Cube, it can gradually become a third-order Rubik's Cube-a large third-order Rubik's Cube.When the time comes, you can apply the third-order Rubik's cube recovery formula to recover easily.

The reason why he feels some headaches now is that he is thinking, how many times does a 17th-order Rubik's Cube need to twist and how long it takes to recover according to the order reduction method, and is this metal sphere positively small?

On the modern earth, there is no wrong record about the restoration of the seventeenth order. It seems that it is seven and a half hours. The current metal ball is afraid that it can't be beaten for ten hours.

"Ten hours." Richard chatted easily.

He can guess that only by successfully restoring the Rubik's Cube can the Rubik's Cube be opened in the correct way, and some key information hidden in the Rubik's Cube can be obtained.

In this way, let's not talk about ten hours, that is, twenty hours.

Richard took a deep breath and was about to twist, suddenly remembering something.

In other words...Is it possible: At the beginning, the Rubik's Cube is actually restored, as long as the Rubik's Cube is opened in a certain way, you can get some information?And now, it is...

Richard turned his head to look at Pandora and asked, "Pandora, have you ever touched this cube?"

"Ah, this Rubik's Cube, it seems... seems to have moved... a little." Pandora asked with wide eyes and asked with concern, "What's wrong?"

"I... uh, it's nothing." Richard gave a strong smile, shook his head, then patted Pandora's head, rubbed his hair, and said, "You... go brush the test tube."

"Oh." Pandora walked sideways happily.

Richard reminded: "Right, if there is a similar situation again next time, don't mess up."

"For... why?"

"Because...may be dangerous."

Pandora tilted her head and thought about the situation just now, then looked at Richard and nodded seriously, "I remember."

"That's good." Li Cha made a noise, rubbed his eyebrows, moved his fingers, and began to operate the Rubik's Cube.

"Kaka Kaka..."

"Kaka Kaka..."
