Mu Ying came back to her senses, looked around, and saw that the three of them had indeed come to the feet of the Rubik's Cube, and if they took two steps forward, they could touch the Rubik's Cube.

And the seaweeds that were still attacking frantically before, it seems that the range of action can only be on the road from the Eye of the Deep Sea to the Rubik's Cube, so when they are close to the Rubik's Cube, they have automatically retreated and regained their calm.

Even looking around, through the not too strong light emitted by the Rubik's Cube, I saw that the seaweed seemed to never exist, and even the human bones disappeared.

The road connecting the Eye of the Deep Sea and the Rubik's Cube is just like ordinary ground, if it wasn't for the real experience of the obstruction just now, who would have thought that there was a hidden mystery here?

Mu Ying pursed her lips in silence and said, "These seaweeds are too good at camouflage, and this is just the first difficulty we encountered. ”

"You must not be careless later, anything that seems harmless is likely to turn into something that kills people in an instant."

Bai Liqing and Jun Jinghong nodded in unison.

However, the seaweed has passed, and everyone should look forward.

No, Jun Jinghong immediately turned his head to look at the Rubik's Cube and observed it carefully.

It's a lot closer to the Rubik's Cube than before, so you can see more details.

"Tut-tut, this Rubik's Cube is really like what Xiao Ying just said, there are grids horizontally and vertically, dividing the entire cube into countless small pieces."

"And look, there's something like a number on these squares ahead of us!"

Following the direction of Jun Jinghong's finger, Mu Ying and Baili Qing really found the number.

In fact, these numbers are not very easy to find, as if someone deliberately hid them, and they were written in the corner.

The color of the characters is almost colorless, and when it is covered by the white light emitted by the Rubik's Cube, it is even more difficult to find.

However, they couldn't stand Mu Ying, and the three of them looked good, and they thought of the concept of the Rubik's Cube in advance, so they were prepared, so they naturally found the number.

"Let's go, get closer and see how these numbers are patterned!"

Mu Ying's proposal was immediately responded to by Baili Qing and Jun Jinghong, and the three of them took the bubble ball and went straight to the square in the southeast corner of the Rubik's Cube.

"Xuanwu, Xiaohuo, Lotus and Little Goose, you are responsible for guarding the surroundings."

While being attracted by the Rubik's Cube, Mu Ying did not forget to be cautious.

"The seaweed is retreating, but it is not a trick for them to retreat, and they have to guard against some other means."

"Baili and I, Jinghong will study the Rubik's Cube, and I'll hand it over to you behind the scenes!"

"Rest assured, master!" The four little ones patted their chests and said.

"The matter of vigilance will be left to us, master, you concentrate on researching!"

"Yes!" Mu Ying rubbed a few small heads in turn, and then focused on studying the Rubik's Cube.

When Mu Ying was talking to a few little ones, Bai Liqing and Jun Jinghong were already observing the Rubik's Cube, so Mu Ying leaned over and asked directly.

"How's it going, what's going on?"

"En......" Bai Liqing frowned in rare embarrassment, and pointed to the number on this square.

"The number is very strange, there are three numbers, like this one square, 5, 12, 3 are written in succession."

"But this square is clearly the first square in the lower left corner of the cube, but there is no number related to 1 in the number."

"And the square on the right side of it is also strangely numbered, 2, 6, 9."

"The two squares are next to each other, why are the numbers not connected at all?"

"And, a square, why use three numbers for numbering? What is this orchestration method? ”

Baili Qing didn't understand it at all, and was frowning and thinking.

"Hahaha...... Jun Jinghong saw that Baili Qing was deflated, and laughed so much that a flower branch trembled.

"Baili, aren't you quite capable, there are actually things you don't understand, it's so interesting!"

Jun Jinghong laughed so much that tears were about to come out, and the green tendons on Bailiqing's forehead loomed.

"Heh, when you laugh at me, do you figure out what the numbers mean?"

"Uh......" In the face of Bailiqing's questioning, Jun Jinghong was gloriously stuck.

"I ...... I don't know. ”

"That's not the end of it." Baili Qing hooked the corners of his lips.

"Let's two half a pound and eight taels, you don't have fifty steps and laugh a hundred steps, it's better to think about it if you have that kind of work."

Jun Jinghong's joke was not successful, but he was scolded, and pouted happily.

"Hmph, I'm sick, I've hurt my consciousness and my brain, and it's natural that I can't think of it for a while."

"But Baili you are not injured, why can't you think of it?"

Anyway, it is impossible for Jun Jinghong to admit that he is not smart, and he has to embarrass the responsibility.

The corners of Bailiqing's mouth twitched, knowing in his heart that he couldn't be as knowledgeable as Jun Jinghong, a naïve ghost, but he just couldn't help his little temper.

"Consciousness is consciousness, and the brain is brain, and for the first time I heard that an injury to consciousness can damage the brain."

"Stupid is stupid, and I don't know how to make a better excuse for myself." The whole book

After finishing these, Bai Liqing felt that his whole body was comfortable, and he redevoted himself to the research of the number full of energy.

"Hello you......" Jun Jinghong was choked and stomped his feet in anger.

"Who do you say is stupid? Who do you say is stupid? ”

"Whoever should be is whoever!" Baili Qing learned Mu Ying's tune and replied.

Jun Jinghong was even more furious, but he was just about to reason with Bailiqing, and Bailiqing had already made a silent gesture first.

"Shhhhh

"Since you have something wrong with your brain, just stand on the side, don't delay us normal people to study the right thing."

Jun has something wrong with his brain and Jinghong is really going to explode, but he himself said that he was injured and couldn't think, and now he can't find a way to refute it at all, otherwise wouldn't he be slapped in the face?

Lifting a stone to shoot yourself in the foot, it's really enough!

"Poof......" Mu Ying, who witnessed the process of the two naïve ghosts fighting the whole process, smiled very unkindly.

"Jinghong, Jinghong, you said that you and Da Bai Pear have never won a fight, whether it is spiritual power or fighting, what is it that supports you to defeat and fight?"

"Boom, boom, ......," Jun cried in the storm.

"Xiaoying, your words are heart-wrenching, the baby is unhappy!"

"Little goose, you see that you are bullying your uncle, you must stand together with your firm brother!"

Goose: "Quack! I am a vigilance for my masters, I am a vigilance for my masters! ”

The goose chooses not to participate and does not stand in line with the strategy of playing stupid.

"Huh, ......" Jun Jinghong was even more sad.

"Even the little goose, you abandoned your uncle, and your uncle is no longer alive......"

"Okay, okay, don't play with the treasure." Mu Ying grabbed Jun Jinghong's back collar in time and asked him to stand up straight.

"Don't be coquettish, I have some opinions on this number, but it needs to be further confirmed."

"Big white pear, Jinghong, you can go around the Rubik's Cube with me!"

Hearing that Mu Ying had an idea about numbers, Bailiqing's eyes immediately lit up.

"Great! Xiaoying, since you have a clue, then we will all follow you, and you can verify it as much as you want. ”

Jun Jinghong also knew that this was a serious matter, and suddenly didn't dare to be skinny, "That's right, Xiaoying, whatever you say, we will do it." ”

In this way, with everyone's support and cooperation, Mu Ying circled around the Rubik's Cube.

The bottom of the sea is inconvenient, and the numbers on the squares that are too high cannot be seen, but Mu Ying wrote down the numbers on the four sides of the Rubik's Cube, the two or three layers from the bottom to the top, and said very firmly.

"I know what those numbers mean!"

"Oh? Tell me about it! Bai Liqing and Jun Jinghong asked in unison, and even the four little ones in charge of guarding couldn't help but eavesdrop on one ear.

"Don't worry, I'll say it slowly, it's actually very simple and easy to understand." Mu Ying said.

"We checked it just now, and the length, width and height of this Rubik's Cube are all composed of twenty squares, which means that there should be a total of 20×20×20, 8,000 squares here."

"There are so many blocks, and they are three-dimensional constructions, and a single number number cannot fully extract their positions."

"And we just walked around and found that the number on the square, no matter which of the three numbers, is the largest is twenty."

"This means that the number represents the order of the position of the blocks in the three directions of length, width and height."

"Think about it, if we number one of the corners of the squares 1,1,1, wouldn't the other numbered squares be well positioned?"

This is actually the concept of Cartesian coordinate system in mathematics.

In spatial analytic geometry, in order to determine the position of any point in space, it is necessary to introduce a coordinate system into space, and the most commonly used coordinate system is the spatial Cartesian coordinate system.

x stands for the horizontal axis, y stands for the vertical axis, z stands for the vertical axis, and xyz is the synonym for length, width and height.

It's just that English and mathematics are not popular in the fantasy world, so Mu Ying didn't say this, but spoke it in her own language.

"And these blocks, as I guessed before, are able to move like the modules in the toy Rubik's Cube, so the number of each block has no connection with the surrounding blocks, which makes it easy to go into the wrong place."

"Hmm......" Baili Qing and Jun Jinghong heard this, and seemed to be woken up at once.

Baili Qing couldn't help but sigh again and again, "It's amazing, I was thinking before, eight thousand squares, it's not easy to distinguish them one by one, just remembering the numbers will give you a headache, and it's even more difficult than setting up a formation." ”

"I didn't expect there to be such a simple way, three numbers combined, each with a maximum of no more than 20, it's wonderful!"

Baili Qing was as excited as if he had discovered a new continent, "This number inspires me, and I think it can be integrated into the arrangement of the formation!" ”

"This kind of numbering method has never been heard of before, and the formation arranged will definitely stump a large number of people!"

Jun Jinghong also thought of this in hindsight, and while thinking that this was a good idea, he couldn't help but feel that he was robbing the limelight.

Is it clear that he is the one who majors in formation?

"Ahem......" Mu Ying naturally thought that Baili Qing's idea was very good, but she still coughed lightly.

"Let's think about this later, let's think about how to enter the Rubik's Cube first, and what can this number help us after entering!"
