　　 "Kaka Kaka..."

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

　　 First of all is the first form of metal balls, that is, ordinary metal balls, there is nothing special. However, once subjected to a strong impact from the outside world, it will become a second form, and produce a terrifying and destructive breath to warn.

This warning is not plain and scary. Richard is very skeptical that if the degree of external shock or damage reaches a limit, the metal ball will explode devastatingly. The power index is rarely 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 **** 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, it is prepared to ensure that the second form of the metal ball is opened by the person in a correct way.

　　As the metal ball is activated, it becomes the second form...

　　 "Kaka Kaka..."

　　 Richard turned a few times towards 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.

　　 "The Rubik's Cube? What Rubik's Cube? What is the Rubik's Cube? What is the Rubik's Cube?" The golden mask was also extremely puzzled.

　　 glanced 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 a prop to exercise your mind, but the Rubik's Cube..."

　　Richard talked, 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, the long vertical line, short horizontal line, short left are carved on each Slash, short right slash, left semicircle, right semicircle-the six elements that make up the Black Spirit Empire pattern.

　　 This is a six-sided cube, and the reason why a sphere appears is because it is a seventeenth order.

　　 Yes, 17th order!

　　 The most common six-sided 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 a fist, there are so many cells scattered all over the body, which makes the scalp numb.

　　 This leads to a twist on this metal ball, and the rotation is not a one-layer unit block at all. It may be a three-layer unit block or even a four-layer unit block. Only twisting with a needle or nail can be sufficiently accurate.

　　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, and the size will be slightly different, undergo some deformation treatment, and eventually change from a cube to a near sphere.

　　 17th order!

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

　　The Rubik's Cube was invented in 1974 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 slowest restoration of the Guinness record of the third-order six-sided standard cube was created by an Englishman named "Graham Parker".

　　After Graham Parker bought the Rubik's Cube in 1983 and made his first contact, 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 just 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 fifteenth, sixteenth, seventeenth-a full seventeenth order!

　　Richard pursed her lips and was not intimidated 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, not to mention 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-after the Rubik's Cube order reaches a certain level, it is no special to continue 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.

　　 First rotate the Rubik's Cube to make the color center of each face of the Rubik's Cube 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 way, 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, the formula of third-order Rubik's cube restoration can be easily restored.

　　Now he feels a headache because 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, about the 17th-order recovery record, if you remember correctly, it seems to be seven and a half hours. The current metal ball is afraid that it can't be beaten for ten hours.

　　 "Ten hours." Li Cha said to herself easily.

　　 He can guess that only by successfully recovering 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.

　　 Since then, let's not talk about ten hours, that is, twenty hours, but also have to do it manually.

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

　　 Say... Is it possible: At the beginning, the Rubik's Cube ~www.readwn.com~ is actually restored, as long as the Rubik's Cube is opened in a certain way, can you get some information? And now, it is...

　　 Richard turned his head to look at Pandora and asked, "Pandora, have you ever moved 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... um, nothing." Li Cha 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 happily to the side.

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

　　 "Why... why?"

　　 "Because...may be dangerous."

　　 Pandora tilted her head and thought about the situation just now. She 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..."
