David glanced at Du Kang, and after determining what Du Kang meant, a hint of suspicion appeared on his face. Pen & Fun & Pavilion www.biquge.info

The fifth-order Rubik's Cube is not something that ordinary people can solve, and even if it is a third-order Rubik's Cube, when it was first created, it stumped a large number of people. If you want to restore it, it is extremely brain-draining.

The more advanced fifth-order Rubik's Cube is even more difficult, and even if you know the tricks, you may not be able to understand and remember the steps. What's more, the lucky Rubik's Cube in his hand is a magical equipment used by his uncle in the imperial capital to exercise his mental power. Although it can't be called complicated or clever, it doesn't take a lot of mental power to turn it once.

David looked Du Kang up and down, cheap coats, cheap parcel boxes, cheap boots...... No matter how you look at it, Du Kang is an ordinary person who can't be more ordinary. Even the appearance is not outstanding, at most the eyes are a little better-looking.

Such a guy doesn't look like a person who can restore the fifth-order Rubik's Cube?

Suspiciously handed the Rubik's Cube to Du Kang, David kindly reminded: "Dude, this is a fifth-order lucky Rubik's Cube, and it takes mental power to turn it." You know what mental power means, right? It's that if you play with this thing for a long time, you will feel extremely tired, like a hard job for a day......"

Before David finished speaking, Du Kang took the Rubik's Cube and looked it up and down, then took it in his hand and began to rotate.

The fifth-order Rubik's Cube has a total of 8 corner blocks, 36 side blocks, and 54 center blocks (48 movable blocks and 6 fixed blocks). Since the structure of the fifth-order Rubik's Cube is similar to that of the third-order Rubik's Cube, some of their solutions can be applied to help with recovery.

The fifth-order Rubik's cube is generally restored by the "reduced order method". That is, the first step is to merge the center block, the second step is to merge the edges, and the third step is to restore according to the third-order Rubik's Cube.

This is one of the most common solutions, but it is also one of the slower ones. Du Kang obviously wanted to help this guy get rid of it quickly and get a good night's sleep. So he used the 'reverse reduction method' that he figured out when he was a child.

Turning the Rubik's Cube steadily with both hands, the drowsy Du Kang restored most of the first side in ten seconds almost with his eyes closed.

This action made David's eyes light up, he could understand Du Kang's steps, and he never thought that the fifth-order Rubik's Cube could be played like this.

However, the next steps were completely incomprehensible to David.

Seeing Du Kang's palm flying, pinching the fifth-order Rubik's cube in his hand, David could only see that the outline around the fifth-order Rubik's cube was gradually restored, and in less than a while, this fifth-order Rubik's cube was almost completed!

How is that possible?, Davy looked at Du Kang with some confusion. But it turns out that this fifth-order Rubik's Cube is indeed about to be unlocked!

At the end of the move, Du Kang yawned and returned the Rubik's Cube to David.

"The Lucky Rubik's Cube sometimes has some special functions, and the contents can only be used by the first person to restore it. The final step is to turn this corner to the left. ”

Du Kang said, motioning for David to finish this last step quickly. He was too sleepy.

David took the Rubik's Cube and looked at it with some excitement.

This fifth-order lucky cube was a birthday present from his uncle Anthony, and last year, his birthday present was a cub of a Warcraft dodo.

With his uncle's character, this year's gift will definitely not be worse than last year's, what kind of surprises will there be?

"Bang Da~" According to Du Kang, the last step is completed. The Rubik's Cube was completely restored, and there was a subtle sound.

"Hum~"

A square in the center of the Rubik's Cube suddenly shot out a light purple light, and a small person the size of a palm appeared three inches above.

The little man was dressed in a magnificent robe and a hat, and under the hat was a fat face, a middle-aged man.

The stereoscopic projection was so real that Du Kang could even see the beard on the little man's face shaking as he spoke.

Such a realistic method, amazing!" Du Kang couldn't help but think.

The little man waved his hand upwards: "Hey, David, my dear nephew." Happy birthday! Looks like you've unlocked the Rubik's Cube I gave you. I have set a small threshold for this Rubik's Cube. You can't have anyone more than the level of a magic apprentice to help you. At the level of a magic apprentice, it would take a lot of difficulty to unlock it. Ha, my dear nephew, it seems that you have restored it yourself through hard work. Well done! You've grown a lot!"

Listening to these words, David glanced at Du Kang and couldn't help but be a little embarrassed. Du Kang also smiled kindly.

"Guess what, what gift I have for your bar mitzvah?" the little man deliberately paused.

After waiting for three or four seconds, David was in a hurry, and the villain continued to speak.

"Hah, yes...... A key! The gift was placed in the safe locker of the Anthony Imperial Chamber of Commerce branch and arrived in Oslia. You'll know when you go. Have a nice trip, dear David. Happy school~"

David scratched his head and rolled his eyes in annoyance. My uncle really likes to sell Guanzi.

After speaking, the stereoscopic projection light gradually weakened, and the projection disappeared. The Rubik's Cube began to click from the center to all sides, and after some changes, a wolf's head key lay quietly inside.

"Congratulations. Du Kang said a word, and began to yawn uncontrollably.

David grinned, "Thank you for helping me untie this thing, it's been bothering me for months." My name is David Oliver, and what about you? I'm in the imperial capital. ”

"Dukang, Dukang Warfitter. ”

"How did you do that? It's incredible, can you teach me?"

Du Kang looked at David, who was like a curious baby, and couldn't help but wave his hand and said, "David, I'm afraid it won't work now...... Can you let me sleep for a while?"

David smiled a little awkwardly and motioned for Du Kang to sleep first, and he took the key and played with it.

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

Imperial capital, Oslia, ******.

The massive magical windmill slowly flew into the harbor and landed outside the massive station building, where the escalator slowly rose to connect the wide hall. The roar of a bald man resounded from inside the windmill.

"The imperial capital's arrived. Hurry up and get out of the car. Don't grind!"

The windmill became bustling, and Du Kang woke up from his sleep.

Looking up and looking around, seeing your huge station building outside the car window, Du Kang's mood immediately became excited.

The capital of the Dalahan Empire, the ****** of Auslia, one of the three high cities of the Empire!

It's a big city!

Du Kang hurriedly got up and wanted to take a look outside. I grabbed my luggage, but I felt empty.

"Hey, Dukang. I'll take your luggage for you, get out of the car. On the way, you said okay, you want to teach me how to restore the Rubik's Cube. ”

Du Kang smiled bitterly, got up and followed David down the escalator.

It is very large, the station building is full of people, and outside the station building are countless huge cars and boats. Du Kang even watched a small spaceship slowly leap over his head, a huge magical vortex roaring at its bottom. This gives the illusion that the steel becomes as soft and flowing as water, forming a whirlpool like water.

"That's Imperial Sixteen, the newest magic airship. The thing we sit on can't compare to it. It can fly all over the forty-eight provinces of the empire in a week, and anyone who flies on it, even from the farthest northwest of the imperial capital, will only take three days. ”

David and Du Kang stood side by side and talked eloquently.

"It is said that the Empire's military magic fleet is equipped with this kind of airship. It's smaller and more flexible, though. Look at the one over there, it's a levitating shuttle, the whirlpool thrust formed by the magic of wind and fire, plus a special metal track, so that the train can travel through the tunnel. Its speed is not slower than that of an airship, but the production cost is too high, and since it was developed, it has been equipped with the three high cities of the empire. ”

"And the ...... over there"

David chattered, but Du Kang held him down. David glanced at Du Kang suspiciously, and followed Du Kang's eyes.

In the corridor not far ahead, several people gathered around and entangled, as if something had happened. A few people scattered around were stopping to watch.

Du Kang and David rushed over to find that three strong men were pulling with a girl in a leather suit. There were also three strong men around who were smiling and explaining something to others.

"What do you want to do? I don't know you, let go!" the girl was cornered and looked around coldly.

A strong man approached with a smile: "Don't make trouble, miss, come back with us." You've been away for a long time, and you're worried. ”

"I don't know you at all, how could my father send some people I don't know to me. Who the hell are you?"

The two strong men stopped talking, and directly reached out to grab the girl.

But the girl's movements are very flexible, but this grasp was unsuccessful.

Du Kang and David slowly approached, but were blocked by a strong man: "Our young lady ran away from home, and we were ordered to take her back, don't look at it." ”

David pulled Radukang: "Let's go, let's leave other people's family affairs alone." ”

Du Kang glanced around the corner and saw that it was the girl who was sitting next to him on the magic windmill, dressed as a man. At this moment, the girl's fur hat had been torn off, and she seemed to be a little flustered.

Something is wrong!

Although the girl didn't ask for help from the people around her, Du Kang looked at the rude movements of those strong men, where did it look like the behavior of the subordinates to the young lady?

And Du Kang can feel the malice hidden in the eyes of these people, which is an intuition that Du Kang has cultivated for many years of survival in the slums.

At this moment, only Du Kang and David were left in the corridor, and the rest of them left in surprise.

Du Kang crossed over a bearded brown-haired man led by him, but stopped abruptly.

"Wait a minute! You say it's her family. Then the two of you, don't look at each other, dare you say what the girl's name is at the same time!"
