The lady who came back from the robbery turned out to be the proud female sword emperor

Leaning on the torch, Li Yunfei looked at this door. The stone door is made of the same material as the outside, and there is no keyhole near the door frame. That is to say, it is not opened by a key, so it needs to be decrypted. what...

He quickly turned his gaze to the central part of the door, and he really found the part that needs to be decrypted. The part of the previous door is a 20X20 sliding block puzzle, but it is different here.

Li Yunfei stared in bewilderment at the three small cubes embedded on the door. The material was not stone, but metal, and Li Yunfei was very familiar with these things.

Rubik's cube?

"what is this?"

The women followed Li Yunfei's gaze and noticed the three Rubik's cubes embedded in the wall, but they had never seen such a thing before.

Li Yunfei silently pulled the Rubik's Cube out of the wall, without much damping feeling, it seems that there is still a certain gap inside.

"It should be to restore this disrupted thing?"

Fu Shishuang was the one with the highest IQ among the women present, she noticed with sharp eyes that the imitation in Li Yunfei's hands was in a state of disorder and disorder, and there were different marks on it, so she naturally thought of this.

"That's right, it should be restored to open the door, and the six sides must maintain a unified mark."

Li Yunfei looked at the Rubik's Cube in his hand and said, there are not six colors on it, but six different imprints to distinguish the six sides, and the imprints on each side are different. Dyeing or something is also easy to fade, so I replaced it with a mark?

No, the point is not this, the point is the Rubik's Cube!

Does the Rubik's Cube already exist in this world?Li Yunfei was a little surprised. You must know that even in the previous world, the Rubik's Cube was something that only existed in the 1974th century. It was invented by Professor Erno Rubik of the Budapest School of Architecture in Hungary in [-]. Independent Diamond Chess is called the three wonders in the intellectual game world by foreign intelligence experts, and the popularity of the Rubik's Cube is a miracle in the intellectual game world...

Li Yunfei once again felt that the Mohist family was a bit miraculous. This ancient relic had surprised him many times, and it was hard to evaluate the degree of civilization it showed.

This shows that Mohism has a lot of attainments in mathematics, and also has a certain understanding of three-dimensional space. At least this kind of thinking is far superior to other forces in the same period. No wonder all national forces want to eliminate Mohism. Otherwise, if the Mo family really rises, the world may have changed a lot.

"Then let me try it, it's just that the six sides are the same, it's simple!"

As he said that, Bai Wushuang took the Rubik's Cube from Li Fei's hand and twisted it at a super high speed. At that speed, Li Yunfei couldn't see clearly at all. Maybe he didn't know how many times he was twisted at that moment. If Bai Wushuang Wushuang really knows how to solve the Rubik's Cube, maybe he can solve it in an instant, but...intelligence is a shackle.

"What! No matter how much you do with this thing, it can't return to its original state! I don't think it's possible to restore this thing!"

Bai Wushuang said angrily, she had twisted so many times, in the best case she got one side together, but after that she didn't know what to do, if she wanted to recover the second side, then the first side It must be destroyed.

This is a common problem of many people who play the Rubik's Cube for the first time. No, it should be said that they do not have a sense of three-dimensional thinking. Of course, most people can solve the Rubik's Cube by memorizing formulas, but that is just an evil way. The real way to solve the Rubik's Cube is Li Yunfei. I feel that I should not rely on formulas, but let my mind sort out all the space transfers before solving it.

"Forget it, husband, this thing is fake, let's smash the door!" Bai Wushuang was still full of anger, the dignified Sword Emperor was teased by a small box, she was very unhappy and was about to smash the Rubik's Cube Continue to smash the door.

"Don't, don't! Don't!"

Fortunately, Li Yunfei quickly hugged his wife. As soon as Bai Wushuang was hugged by him, his face immediately turned pink. reduction"

"Of course, and it's the easiest..."

As Li Yunfei spoke, the corners of his mouth couldn't help twitching. He just pulled out the simplest Rubik's cube present. This is a third-order Rubik's cube. He glanced and saw that the other two Rubik's cubes still embedded in the wall were fourth-order Rubik's cubes. and the fifth-order Rubik's Cube.

The third-order Rubik's Cube is a 3×3×3 cube structure composed of 26 color blocks.The third-order Rubik's Cube, through rotation, has a total of nineteen changes of 4.3×10. Although it is the simplest, it is impossible to try it out if you twist it casually and quickly like your wife.

The simplest third-order Rubik's cube is like this, let alone the fourth-order and fifth-order Rubik's cubes, and the amount of change in it has risen exponentially.

The Mohist's ability to design such a door-opening code is undoubtedly the embodiment of the strongest brain in this era.

However, this is not complicated for him, because of the treasure house of wisdom, he only needs to take a look at the Rubik's Cube to understand all the ways to solve it in space, and then he can calculate the solution method with the shortest steps, so Li Yunfei This door can be opened at any time now.

It doesn't matter if it is a higher-level Rubik's Cube, and the same strange-shaped Rubik's Cube can't trouble him.

"I want to try..."

Fu Shishuang said with a flushed face, partly because she was excited by new things like the Rubik's Cube, and partly because she saw the hug between Bai Wushuang and Li Yunfei. Isn't it embarrassing in front of a large crowd?

"You want to try? That's fine, I wish you success." Li Yunfei smiled and handed the third-order Rubik's Cube to Fu Shishuang, and then he looked at the other two Rubik's Cubes.

Let him solve these two. . . . . . . .to be continued

Chapter 359 Spanking!

After taking out two Rubik's Cubes from the wall, Li Yunfei glanced at them realistically, and the treasure house of wisdom began to operate instantly, and then Li Yunfei began to operate at a leisurely pace.

After all, he is not Bai Wushuang, and he cannot achieve that kind of extreme hand speed.

Therefore, even if he had such computing power, if he really wanted to participate in the Rubik's Cube competition in the previous world, he might have to be brushed off, simply because his hand speed was not enough.

It took about a minute for Li Yunfei to solve the two Rubik's Cubes slowly. He was still lazy, and he closed his eyes and yawned when solving the Rubik's Cube, but it doesn't matter if he opened his eyes or not.

After all, after he read the details of the six sides of the Rubik's Cube, the entire Rubik's Cube was realized in his mind. All the steps and all the pictures don't need to be seen with his eyes, but he can do it with his heart.

"Restored..."

Li Yunfei said lightly, probably because his brain's calculation power is too powerful now, he doesn't think it is a proud thing to restore the Rubik's Cube, but he just thinks it's like cooking a side dish, oh no, cooking a dish is even better than this Much trouble.

He wasn't shocked, but the others were already dumbfounded.

Bai Wushuang, Tang Xin Lolita, and even Fu Luoying all stared at the Rubik's Cube in Li Yunfei's hand, their small eyes were filled with great shock besides great doubt.

"It's really restored?" Bai Wushuang rubbed her eyes. She tried it herself. It's impossible. She twisted it thousands of times, and the result became more and more chaotic...

"Although I don't understand it very well, but it looks very powerful..." Tang Xin's eyes widened. Although she didn't test it with her own hands, she was watching when Bai Wushuang started. For a person with the speed of Bai Wushuang, when Bai Wushuang twisted, it was actually equivalent to listening to her twisting, so she also felt that the thing was very evil and could not be restored to its original shape.

"Ohhh!!! Brother Yunfei is amazing!"

Fu Luoying applauded on the other hand. Although she couldn't understand anything, was there any doubt about the fact that Brother Yunfei was very good?

Feeling the adoring and shocked gazes of the women, Li Yunfei stroked his forehead, this is really normal, damn it, I always feel like a child being coaxed by adults, but... for some reason, the feeling of being flattered is still I really can't bear to hear it.

"Yunfei, have you recovered?"

Fu Shishuang also looked over in amazement, only to see that the two Rubik's Cubes in Li Yunfei's hands were flawless, showing their respective six-sided marks.

For a moment, Fu Shishuang bit her lip, looked at the Rubik's Cube in her hand in a blink of an eye, and her face was a little puffed up, it was because she was angry with herself and dissatisfied with herself.

Obviously I started before Yunfei, but I didn't finish either...Yunfei finished two!Moreover, no matter how you look at Yunfei's two difficulties are higher than his own.

Li Yunfei was almost not amused when he saw Fu Shishuang's expression, how could all the women around him know this trick, the puffy little face looks really lethal, but it is different from Bai Wushuang's, Bai Wushuang's small face is puffy Most of the time, he is usually acting like a baby with himself, but with Fu Shishuang's words, this guy is obviously digging into a dead end.

But no matter what, Fu Shishuang really surprised herself.

Because Li Yunfei saw the Rubik's Cube in Fu Shishuang's hands, it was almost 80.00% complete...

It is the first time to play Rubik's Cube, if you can make this in 1 minute, you are definitely a genius!

Li Yunfei said in his heart, if Fu Shishuang lived in the previous world and had received education in the previous world, he would definitely be a science god level figure, right?Just when he taught Fu Shishuang arithmetic and some science knowledge before, he discovered that Fu Shishuang accepted it very quickly. No wonder he was regarded as his successor by his old mother before. I have to say that my mother's eyes are sharp and accurate.

"Don't worry, we'll wait for you, aren't you almost done?"

Li Yunfei smiled and said to Fu Shishuang.

"Forget it, come Yunfei, I'm just wasting time..." Fu Shishuang passed the Rubik's Cube over as she spoke, still looking sullen, and seemed to be still autistic, which made Li Yunfei dumbfounded, It seems that it is my own fault, and the performance is a bit shocking.

But Li Yunfei is not stupid, how can he really answer the Rubik's Cube at this time?After all, one's will cannot be coddled. He was afraid that he would wear down Fu Shishuang's heart for scientific research and exploration, and what he needed was the indomitable Fu Shishuang.

He pushed the cube back, a smile on his face.

"Won't waste time!"

"But obviously I'm wasting time...Yunfei, come here"

"If I say no, I won't! Fu Shishuang, did my mother choose a successor who is afraid of failure like you? You shouldn't be scared by me, right?"

Li Yunfei knew very well that with Fu Shishuang's self-esteem and respect for his mother, he would definitely be able to get rid of the current autism.

Unfortunately, he misjudged, Li Yunfei didn't realize that Fu Shishuang was also a woman, and as long as she was a woman, she might play petty temper sometimes.

And Fu Shishuang is so smart, of course she knows that Li Yunfei is provoking her, and even the teacher moved out, it's too much...

"Then I'm that kind of person..."

Fu Shishuang said so, unconsciously, she has changed a lot around Li Yunfei.

She felt that there was a special magical power around Yunfei, which could change people's hearts, change her formerly cold heart, no longer rigid, and no longer so calm, but... this feeling is a bit good. ? ? ?

Where did Li Yunfei expect such a situation, he showed a trace of astonishment, which made Fu Shishuang feel happy and refreshed.

That's it!Yunfei, even if you are so smart, you never thought that I would answer like this!

She suddenly felt that she had the temper of a little girl, and Fu Shishuang's face flushed slightly, and she didn't know how to judge her own transformation.

"If you don't continue, I'll spank your ass!"

Li Yunfei pursed his mouth and said, he really didn't expect Fu Shishuang to answer like this, but he understood from the other party's expression, it's useless to treat smart people like Fu Shishuang with words, so...he can only surprise .

Although saying such words is not in line with his image, the effect is not immediate.

"What!...I'll restore it right away!"

Fu Shishuang's face turned even redder, and she didn't dare to tease Li Yunfei anymore, so she hurriedly started to solve the Rubik's Cube, while doing so, her heart was beating wildly, she really didn't expect Yunfei to say such a thing.

"Tsk, this man is hopeless"

Tang Xin loli was on the side, looking at Li Yunfei with disdain, and took a step or two back. . . . . . . .to be continued

Chapter 360 A Ring

Bai Wushuang was grinning, she could tell that her husband was joking, but seeing Xiao Shishuang's expression like that was really interesting.

"Brother Yunfei, if Miss doesn't want to, why don't you shoot me!"

Duang!

As soon as the words fell, Fu Luoying squatted on the side again, silently thinking about the hateful Great Demon King!

Another minute later, Fu Shishuang restored the third-order Rubik's Cube, and then handed the Rubik's Cube to Li Yunfei with a blushing face, never daring to utter a single word, probably still shy.

"Isn't this a good job? You have to believe in yourself in the future." Li Yunfei said in an appreciative tone after holding the third-order Rubik's Cube.

Recovering the Rubik's Cube in 2 minutes, for those who are exposed to the Rubik's Cube for the first time, this is already a miracle, right?Especially if this is a native of the ancient people.

Fu Shishuang, who was praised, dodged her eyes and didn't look at Li Yunfei, but it could be seen from her dangling little hands that there was nowhere to put them, that she still liked being praised.

While speaking, Li Yunfei had already returned to the door with three Rubik's Cubes in hand. He inserted the three Rubik's Cubes in order, and then stepped back a few steps to wait for the door to change.

rumbling...

Just over ten seconds after the Rubik's Cube was inserted, the door was gradually opened. It seems that the Rubik's Cube is only the function of the key, and this time there is no dark layer.

The door opened, revealing a bit of foul air, which was obviously not a good thing.

However, Bai Wushuang and Tang Xin's eyes and hands were quick, and they immediately used their internal energy to form an invisible cover to protect them from it, so that they could not be harmed.

"A small room?"

Li Yunfei walked in, which was much smaller than the space above, at best it was only sixty square meters.

And in this room, there are not many things, just a table.

On the table, there is a small box.

"Looks like it's all about saving the box?"

As Bai Wushuang spoke, the white shadow flickered, wanting to touch the box, but she came back in an instant.

"There are ink stones...the whole table is ink stones..."

Bai Wushuang frowned and said, as soon as she got close to that table, she felt the internal energy in her body flow away, so she didn't dare to act rashly, because if there were any harmful mechanism, she might be killed by Mo Shi Influence cannot be avoided.

"The whole table is made of inkstone?!"

Li Yunfei and the others present were all surprised, and Fu Shishuang didn't care about being shy anymore, she tried to get closer, and immediately felt the suction of the internal energy, "Yes, it's the ink stone, and there is such a big piece... "

Inkstone is a very rare thing... and there is a table here that is made entirely of inkstone. How is this not surprising?

As expected of the Mohists before the dynasties...

"The box guarded by Moshi..." Li Yunfei showed a hint of curiosity on his face. It seemed that it was to prevent others from breaking in, so there must be a way to distinguish the enemy from us.

Li Yunfei began to glance around, it seemed that it was another decryption game.
