Magus Tech Chapter 376: 17-order Rubik’s Cube
"Ka Ka Ka..."
After operating the deformed metal ball, Li Cha roughly figured out the situation of the metal ball.
First of all, the first form of the metal ball is an ordinary metal ball, and there is nothing special about it. However, once it suffers a strong impact from the outside world, it will change into its second form, and emit an extremely terrifying and destructive aura as a warning.
This warning is not scary for nothing. Li Cha is very suspicious. If the external impact or damage reaches a certain limit, the metal ball will explode with devastating destructive power. The power index is at least a thousand T level Yes, that is, thousands of tons of TNT explosives exploded, 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 wizards, even the second-level wizards and even the third-level wizards will not be able to resist.
This design should be prepared by the manufacturer of the metal ball, in order to prevent the metal ball from being forcibly disassembled and destroyed, and to ensure that the second form of the metal ball can be opened in the correct way.
As for the second form that the metal ball becomes after being activated...
"Ka Ka Ka..."
Li Cha turned the transformed metal ball a few more times, narrowed his eyes slightly, and said to himself: "The Rubik's Cube."
Well, Rubik's Cube!
……
"The Rubik's Cube?" Pandora looked curious after hearing Li Cha's words.
"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.
Glancing at Pandora and the golden mask, Li Cha tried to explain: "The Rubik's Cube is the Rubik's Cube. You can use it as a toy, or as a tool to train your thinking, but the Rubik's Cube..."
As Li Cha spoke, his brows gradually frowned.
The second form of the metal ball in his hand is indeed a Rubik's Cube, a true Rubik's Cube, with different marks on each of the six sides—although there is no color division, but each of them is depicted with long vertical lines and short horizontal lines , short left slash, short right slash, left semicircle, right semicircle—the six elements that make up the pattern of the Black Spirit Empire.
This is a six-sided Rubik's Cube, and the reason why it appears as a sphere is because it is of seventeenth order.
Yes, the seventeenth step!
The most common six-sided Rubik's Cube is the third order, that is, there are nine unit blocks horizontally, vertically and vertically on one surface. But now there are a total of 289 unit blocks of 17 horizontally and 17 vertically. In a volume that is no more than the size of a fist, so many unit blocks are densely distributed, which makes people feel scalp numb.
As a result, if you randomly twist the metal ball, what you rotate is not a single-layer unit block at all, it may be a three-layer unit block or even a four-layer unit block. Only by twisting with a needle or fingernail can it be accurate enough.
In order to ensure the smooth rotation of the densely packed unit blocks, some unit blocks at the corners will be very close to the center ball of the Rubik's Cube, and the size will be slightly different, and some deformation processing will be carried out, finally changing from a cube to a near sphere .
Step seventeen!
Li Cha grasped the deformed metal ball in his hand, feeling heavy, and his heart was also heavy.
The Rubik's cube was invented in 1974 by Ernuo Rubik, a professor at the Budapest School of Architecture in Hungary on the modern earth.
Let's not delve into how the Black Spirit Empire had such a thing hundreds of years ago, 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 comes into contact with the Rubik's Cube for the first time, he is not proficient in any mathematical principles, does not know any technical formulas, and does not have a relatively outstanding thinking ability, but only relies on his feelings to recover, then it may take days, weeks, or even months. .
This is not an exaggeration.
In fact, on the modern earth, the Guinness record for the slowest recovery of the three-order six-sided standard Rubik's Cube 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 after he was disrupted.
This is just the simplest three-order six-sided standard Rubik's Cube. As the order increases, the difficulty of recovery will rise linearly.
Fourth, fifth, sixth...
Now there are fifteen, sixteen, seventeen—a full seventeen steps!
Li Cha pursed his lips, not intimidated by the seventeenth-order Rubik's Cube.
He knows the mathematical principles involved in restoring the Rubik's Cube, and he also understands some common methods of restoring the Rubik's Cube.
In fact, not to mention the seventeenth order, even the twenty-seventh order is not a big deal-the record of the Rubik's Cube manufactured on the modern earth is the thirty-third order-when the order of the Rubik's Cube reaches a certain level, continue to increase and There is no special significance, because it does not increase the difficulty of thinking about recovery, but simply increases the workload of recovery.
One of the most common ways to restore a high-level Rubik's Cube is the down-level method.
Turn the Rubik's Cube first, so that the color center of each side 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 merge.
In this way, no matter how perverted a high-order Rubik's cube is, it can gradually become a third-order Rubik's cube—a big third-order Rubik's cube. At that time, it can be easily restored by applying the formula for restoring the third-order Rubik's Cube.
Now the reason why he feels a little headache is because he is thinking about how many twists and how long does it take to restore a seventeenth-order Rubik's Cube according to the lower-order method, and the metal sphere is extremely small?
The recovery record of the seventeenth order on the modern earth, if I remember correctly, seems to be seven and a half hours. The current metal ball may not be able to hold it for ten hours.
"Ten hours." Li Cha said to himself easily.
He can guess that only by successfully recovering the Rubik's Cube can he open the Rubik's Cube in the correct way and obtain some key information hidden in the Rubik's Cube.
In this way, don't say ten hours, even twenty hours, you have to do it yourself.
Li Cha took a deep breath and was about to twist when he suddenly remembered something.
By the way... Is it possible that the Rubik's Cube ~IndoMTL.com~ was actually restored at the very beginning, as long as you carefully open the Rubik's Cube in a certain way, you can get some kind of information? And now, it is...
Li Cha turned his head to look at Pandora, and asked aloud: "Pandora, have you ever moved this Rubik's Cube?"
"Ah, this Rubik's Cube, it seems... seems to have moved... a little bit." Pandora opened her big eyes and asked with great concern, "What's wrong?"
"I... um, it's nothing." Li Cha showed a strong smile, shook his head, then patted Pandora's head, rubbed his hair, and said, "You... go and clean the test tube. "
"Oh." Pandora happily walked to the side.
Li Cha reminded: "By the way, if there is a similar situation next time, don't move around."
"For...why?"
"Because... there may be danger."
Pandora tilted her head and thought about the situation just now, looked at Li Cha and nodded seriously: "I remember."
"That's good." Li Cha said, rubbed the center of his brows, moved his fingers, and began to operate the Rubik's Cube.
"Ka Ka Ka..."
"Ka Ka Ka..."
