"What's the matter?" Sisshan asked, confused, and even a depressed Leo looked up to listen carefully.

"The sharp-toothed demon rats not only have a keen sense of smell, but also are very sensitive to ground vibrations because they live underground all year round, and under their perception, they actually find ......" Haixin paused when he said this, and he looked at Leo and Leo who were anxiously waiting for the next step.

What he was going to say next was also incredible, and he didn't know if they would believe him or say that he was fantastic......

"Tell me what? Leo didn't give Haixin a good tone, how did this kid go.

Haixin still said it, only to hear him say: "The demon rats found that the ground under our feet was moving...... After saying this, Haixin touched his nose and looked at the two of them with some embarrassment, he himself was a little unconvinced.

The magic lamp on the wall in front of him was obviously motionless in front of his eyes, and there was no sense of movement under his feet, and he was a little suspicious...... Did the demon rats take the rat pill? Something went wrong?

"This ...... How is that possible?" Sissan smiled, pushing her black-rimmed glasses in disbelief.

Haixin pursed his lips, he was about to explain, saying that he was just joking, but Leo suddenly slapped his palm and exclaimed loudly: "Ahhhh

This exclamation startled Haixin a lot, Leo couldn't have been fooled by his fallacy just now, right?

At this time, Leo rolled up his sleeves and raised his arm to the sky, and the pet galaxy on his arm quickly transformed into a metal ball.

And when Leo finished reciting a short but jerky incantation, something strange happened, the metal ball actually floated there out of thin air after Leo withdrew his palm support, and it was motionless in mid-air!

"Ahh

Sisshan felt that she was getting more and more unable to see through this Leo, but surprise was surprise, but she didn't ask much.

Haixin didn't understand Leo's intention in transforming the galaxy into this floating metal ball, and they watched, waiting for Leo to explain.

When it is young, the metal ball begins to spin, it spins faster and faster, and at the same time emits different colors of light, such as red, yellow, blue, green, white, and so on.

The light was gentle and unblinding, allowing Haixin to clearly see that the different colors of light were creating a regular image that was somewhat similar to the topographic distribution model in the barracks.

The image gradually appeared, and Qian Shan and Hai Xin suddenly realized at the same time, and Qian Shan said in a somewhat excited tone: "This, this! This is the terrain detection magic guide?"

Sissan's attitude towards Leo had also changed a little at this time, and she felt that this aristocratic young master was at least much more capable than the pompous children she had seen before.

Haixin noticed that the three of them were constantly moving towards the top of the passage in that image, and Haixin said in surprise: "Could it be that the ground under our feet is moving?"

"Yes, not only the ground, but also the walls are moving, and they are moving at a constant speed so silently that we can't even feel it. Leo nodded.

Haixin stretched out his hand and touched the wall and sighed, "Oh God......! What a huge and amazing project it is. ”

"Look ......" Qian Shan then motioned to Haixin and Leo to look at the top of the stairs, Haixin looked up, and suddenly his whole face turned into a bitter melon, it turned out that when the three of them stopped to talk and study, several people were actually sent back to the exit position.

At this time, it had been nearly an hour since they set off, and not only did they not go down to the underground magic crystal library, but they didn't even go out a meter, and they walked so long that they were just standing still......

"I didn't expect that this moving staircase was so well-made, its movement was so uniform and smooth, we couldn't feel it trembling at all, and the most amazing thing was that the wall was also moving along with the stairs at the same time, so that people didn't feel the slightest bit of abnormality. ”

Sisshan looked at the staircase at the top of the staircase and marveled, the stairs, the walls, and even the magic lamps were constantly teleported and hidden into the walls, and the design was ingenious.

"When did it start moving? Oh! I see! The tremor almost caused me to fall to the ground! It wasn't the castle that was shaking, it was the staircase that was moving!

"Since it's moving at a constant speed, why don't we run downstairs as long as we are faster than it?" Sissan.

"Well, it stands to reason that. Leo nodded.

Haixin said at this time: "But this is too slow, we have wasted too much time, I summon the flying mount and let's fly down!"

Haixin summoned three griffins, the griffons were too large to accommodate one in the staircase passage, and the three of them flew into the passage one after another led by Haixin, and the griffins flew in mid-air on the stairs without making any contact with the stairs, so that they would not be affected by the movement of the stairs.

The griffons were fast, and it didn't take them long to cross the stairs to an underground passage, and they stood in front of an archway, but the sight of them was so shocked that they thought they had passed through another dimension.

At this moment, a spectacular underground world of construction appeared at their feet, and they had never expected such a scene under Mororien Castle.

The underworld is a complex of seven shimmering, colorful buildings connected by six smaller cylindrical towers arranged in a hexagonal shape around a large tower in the middle.

These seven towers are all inlaid with demonic beast crystal nuclei of various colors, and those rays of light are emitted by these demonic beast crystal nuclei, making people look full of brilliant dreamy colors.

At this time, they are connected to the top and bottom, like a magnificent optimus pillar, they are not only the pillars of the Morrowian Castle above, looking at their arrangement, plus the glowing demonic beast crystal nuclei on these towers, it is thought that they provide the source of power for this Morrowian Castle.

If I'm not mistaken, the largest tower in the middle should be the destination of Hai Xin and the others' trip - the underground magic crystal library!

The passage connecting the towers was like a "sky bridge" in the air, and the three of them walked on it to approach the main tower in the middle, and when they walked a few dozen meters away, one of the six small towers suddenly opened its iron door.

Then, several people saw a black shadow rushing out of the door, the black shadow was as fast as lightning, making it impossible to recognize, and when the black shadow landed, they could see it completely, it turned out to be ...... This is a mechanical dog with all kinds of weapons almost armed to the teeth!
