Gu Yue followed Xu Qing and walked slowly in the passage, always paying attention to everything around him, although he had been here once when he was a child, he didn't know much about this place. All he knew was that this was a place of confinement, and no one would usually come here. This was the first time he had taken a closer look at the place, and although he had realized the difference between his home and the outside world after so many years of schooling outside, he sometimes thought that their family might be a superpowered family, and everyone had magical abilities, just like mutants. But this time when he came back, everything was still beyond his cognition, and he didn't see how the mechanism worked just now, and these three passages felt full of mystery.

"Uncle Xu, what's going on in this Dragon Cave? Gu Yue couldn't help but ask Xu Qing about the ins and outs of this place.

"This dragon cave is complicated to say, and it is related to the formation of the whole village. Xu Qing told Gu Yue the secret of the Dragon Cave as he walked.

This island is not really an island, but a huge artifact, or a machine. The reason why it is so effective in hiding itself is that it is not a fixed island, but can move and even dive into the deep sea.

The perennial layer of fog on the outside of the island is its protective cover, and even when diving into the deep sea, the people on the island will not feel it, and all the sea water will be blocked out by that protective cover.

And this island or machine, everything on it is the decoration that Xu Qing and Gu Yue's parents brought those students to find, in fact, the original appearance of this island is an oval flat stone plate, and all the decorations are added later, only this dragon cave is brought by the island itself.

The three passages connected here lead to three different places inside the stone pan, like the inside of a large submarine, each with a different function.

The place connected to the passage on the far right is like a rest room, there are several stone rooms for resting, and the things inside have some magical effects, Xu Qing and Gu Yue's parents have cultivated here, and that lounge seems to have a bonus to cultivation, making the three of them progress rapidly.

The middle passage is connected like a wheelhouse, and inside is a huge space where you can monitor and manipulate any part of the island, control everything in the entire stone pan, and see what is happening anywhere on the island through a special device. The most important thing is that this cab can be remotely controlled, and the basic operation of the island can be controlled without going in to operate, and even move anywhere. This remote control is the contents of the stone box that Xu Qing took from the semicircular vault of the nearest place when he took Gu Yue away, that is, the wooden board that Xu Qing operated in his hand when he entered the island just now.

The passage on the far left, which is the passage they are walking on now, is connected to a storage room, which also has a special function, no matter what is placed in it, it will not be damaged, this warehouse is as if it has stopped time, and everything put in it will not change in any way. If you put food in it, it will never spoil, if you put it in iron objects, if you put it in any animal, it will be in the same state as it was put in, and it will never grow.

Just when Xu Qing explained the secret of the Dragon Cave to Gu Yue, the two seemed to have come to an end. Gu Yue found that this was the place where the submarine was put when Uncle Xu took him away last time.

"This was where we walked last time. Without waiting for Gu Yue to ask, Xu Qing gave an answer.

"But this time our goal is not to go, but to be here. Xu Qing didn't explain too much, but was busy working on the stone wall next to him, and the stone wall in front of him slowly slid upward, leaking out of the huge storage room inside.

"Let's go, come in. Xu Qing said and took the lead and walked in,

"It's so big here. Gu Yue followed Xu Qing into this stone room, the space inside was very large, twice as large as the vaulted stone room outside, the difference was that it was not a vault, but a flat roof.

The inside of this stone chamber is empty, only a few open wooden boxes are piled up in the corner, and there is a one-meter-high stone pillar on the ground in the middle, and there is a shelf on the top of the stone pillar, and the iron shelf is empty, but it is clear that there used to be a singing thing here, but now the thing on it is gone.

"And so it was. Xu Qing was a little surprised, and said with some annoyance.

"What's wrong Uncle Xu, what's wrong with this?" Gu Yue immediately asked Xu Qing.

"It used to be full of stuff, but now it's empty, and it looks like those people have already been here. Xu Qing said.

"You mean that the people who attacked them actually got here? How is this possible, even I don't know about it. Gu Yue said in surprise.

"I don't know the specifics, but everything here has been taken away, and it can't be our own people. Xu Qing said.

"Then what do we do now?" asked Gu Yue anxiously.

"Don't panic, let's go to the other two passages first. After speaking, Xu Qing took Gu Yue back the same way, and walked into the middle passage from the entrance.

The passage in the middle was significantly shorter than the one earlier, and it didn't take long for it to come to an end. At this point, Gu Yue finally saw something different, everything before was stone, but at the end of the passage here was an iron door, there was a combination lock on the door, Xu Qing entered a string of passwords, and the iron door slowly opened, and the two walked into the cab.

This room is twice as large as the storage room just now, and directly opposite the door is a metal console, with dense joysticks and buttons of various colors flashing, such a new appearance, metal texture, giving people the feeling of a sophisticated spaceship, with a complex operating system, and mysterious functions.

There is a seat on the right, and the bottom of the seat seems to be tightly connected to the floor of the house. In front of the seat was a large cylinder, and on top of the pillar was a hemispherical body, like a black spherical gem, shining with a dark light, and I don't know what it was for.

What attracted Gu Yue's attention the most was the furnishings on the left. There is a seat on the left, in front of the seat is a huge crystal wall, transparent, crystal clear like a crystal wall stands quietly in front of the seat, occupying half of the room, and through this crystal wall, you can see that half of the room is this kind of crystal wall, lined up layer by layer in front of the seat, just like the bookshelves in the library of Gu Yue High School.

Xu Qing walked to the seat on the right, touched the black ball, and then walked to the console in the middle, touched the button on it, as if remembering something, and finally he stood in front of those crystal walls and sat down on the seat.
