But any hidden means and mechanisms are nothing to hide in front of Lu Yu's powerful spiritual power, although his spiritual power has been shielded a lot here, but the distance of dozens of meters is still no problem at all, when Lu Yu scanned the entire underground space with his spiritual power, he found an abnormality.

A few meters below the pool filled with the essence of the Yuan Stone was actually empty, and there was a large space below, and this space was much larger than the place where they were.

When he was outside just now, due to the fact that this underground space blocked his spiritual power, Lu Yu scanned it with his spiritual power and did not find it, and now at such a close distance, this place was finally exposed to Lu Yu's spiritual power.

And Lu Yu finally understood why such a high-level treasure had not been discovered by the demon of the sun and the flying feather of the moon, because even if their spiritual power could extend to the lower realm, it was not easy, and it was impossible to explore this place, so these things could be preserved until now.

"Brother, are you alright?" Lu Xiaoxiao waited on the side for a long time, and saw that Lu Yu's face was always changing, so he couldn't help but ask a little worriedly.

"It's okay, don't worry." Lu Yu smiled.

"Then you haven't told me yet, what kind of treasure is that lotus?"

"That? It's a very precious treasure, put it there first, and then take it away when we leave, and I'll take you to a place first. "The white lotus is placed there, and the fragrance it exudes helps to awaken the mind and calm the nerves, and can assist in cultivation, so Lu Yu doesn't plan to take it off for the time being, and will talk about it when he leaves here.

"Where are you going?"

"Follow me and you'll find out." Lu Yu pressed a few stones in each of the four directions of the stone wall in order, and finally jumped up and pressed it on the position of his head.

There was a "creaking" sound, and a stone gate appeared in a corner, this door was very special, boxy, the same height and width, about two meters.

Seeing the stone door open, Lu Yu greeted under the surprised eyes of the fight: "Follow me." With that, he walked in first.

Entering the stone gate, it is a downward staircase, the staircase is very wide, it is not a problem to walk four or five people side by side, and on both sides are large pieces of energy yuan stones that emit fluorescence, illuminating the whole space very brightly.

I didn't go far, a turn, that is, a height of more than ten meters, the stairs reached the end, and a huge space appeared in front of everyone, and the space was full of light, because there were several huge energy stones above the space to provide a light source. Illuminate the entire space as bright as day.

The height of this space was about six or seven meters, but the distance from the entrance where they came down to the opposite side was several hundred meters, and the width was also hundreds of meters, about the size of two or three football fields.

There are a lot of houses in the space, about dozens, and it can be seen that there were many people living here in the past, and there are some places where flowers and plants are planted near the edge, and there is a strong aura here, even if there is no sunlight, some plants can grow. In the corner on the other side, there are still some places similar to martial arts training grounds, and some weapons that have rotted and cannot be seen to be of any material are discarded at will.

"What kind of place is this?" Lu Xiaoxiao was a little confused, there was no such place in her treasure map.

"You can take a look at it, pick some of your own houses, and I'll go and see there." After Lu Yu finished speaking, he walked towards a room that looked the largest and most unusual.
