Ways to level up the undead (1)

After walking through a small arch, Zhao Hai and the Queen entered a small room. The room was about 100 square meters in size, but it was about five meters tall. In the middle of the room was a pool. In the middle of the pool was a small tree.

The tree was very strange. It was green and transparent, as if it was carved from green crystal. It didn't look like a plant at all.

What Zhao Hai found the strangest was that the tree only had nine thin branches, and each branch only had one leaf. Each leaf looked like it was carved out of crystal, but the color of the veins was slightly darker, making it look very beautiful.

However, one of the nine leaves had already turned slightly yellow, as if it was slowly withering.

On the side of the pond, there were a few puffs. It was obvious that these puffs were very clean and were used by people.
