Lu Xi pressed his head and told a few people.

A few people seemed to understand it.

Mu Tangyi studied the black box, and accidentally closed the place where the black box was opened out of the notebook.

She wanted to bring it up again, but she couldn't figure it out.

Mu Tangyi was stunned for a moment, and just wanted to touch the entire box again, but the black box began to glow slightly, floating in mid-air, and began to change shapes.

The black box turned into something like a Rubik's cube, with different numbers 1-6 written on each of the six sides.

It's a third-order Rubik's Cube.

In the next second, the Rubik's Cube began to scramble itself.

Mu Tangyi was stunned, the Rubik's Cube flow arose in the school for a period of time last semester, and when she got the Rubik's Cube, it was still so simple as a third-order Rubik's Cube, and she subconsciously began to restore it.

Mu Tangyi's hand speed is not good, but it is slow, and about 50 seconds is enough to restore.

It's not as good as a god, but it's not much different from Qionglan's average student speed.

Some people calculate that they can already restore the third-order Rubik's Cube in twenty or thirty seconds.

After the black box was restored, it changed back to its original appearance, and the whole box was black, but the difference was that it opened a small opening.

"What is this?" Mu Tangyi asked.

She just asked, and didn't think she could hear the answer.

Cheng Yu, Mu Tangyi and Gu Yiyi, who were present, looked at it for a long time, but they didn't understand what this was.

Lu Xi sorted out the memory fragments and pulled out the purpose of this thing from the memory, "It seems to be used to put things." ”

"Isn't it?" Cheng Yu was a little disgusted, "In such a small place, you may not be able to put a ball of paper in it." ”

Mu Tangyi nodded in agreement.

Lu Xi said: "This is used to put paper." ”

Lu Xi looked at his memory and suspected that this black box was a high-tech product.

Because it doesn't feel like something that is unique to this era.

It is even less like a product of the immortal cultivation world where his ancestors were at the beginning.

It is connected to Lu Xi's space, and everything in the space can be taken out of it, but every time you want to take something out of it, you have to open a smart lock.

Smart locks have different shapes, and they may not be square, but they must be black.

The third-order Rubik's Cube is the easiest of all the ways to open.

couldn't explain it in a few words, so Lu Xi demonstrated it to them.

She went with a few people to the place where she stacked her supplies.

It was also halfway up the mountain, and it was bare, just like the rest of the place.

Jiang Yuxi, as the only one who had wandered around the space, didn't find this place.

It's not that it's hidden here, it's that Lu Xi didn't take the materials carefully when he first received them, and he directly collected them all at once.

The space didn't feel Lu Xi's instructions, so he arranged these materials in the most suitable way.

The materials are not on the mountain, but very unscientifically in the mountain.

There was a cave there, the entrance of which was pitch black, slightly hidden by desolation, and not so conspicuous.

Several people looked at the dark cave and couldn't believe it.

"Sister Xi, what are you doing putting the supplies in the mountain?" Gu Yi said.

There is such a space for such an ungodly prop, and a few people think that it is nothing for Lu Xi to collect materials, but who collected the materials and stuffed them into the cave?

How many things can you put in a cave?

And it doesn't look like the hole is very big.
