Carvings?

"Oh, my!" Lin Wu exclaimed as he saw the carvings on the walls.

Unlike the carvings on the door, these ones were very well defined and could be seen clearly. They depicted a great battle between cultivators. There were many different types of them, some were sagely looking, some were demonic looking, some had muscular bodies that were laid bare while others that had beastly looking features.

But the one thing that was the most shocking was that they were all fighting on one side and they had a common enemy. The enemy was strange though; it had no fixed shape or form. It would appear like a cloud and turn into a liquid. It would shift into a solid form and appear as if a rock.

This thing did not seem to attack the cultivators directly, rather it would absorb and take over everything that it covered. It would slowly spread and take over worlds, one by one.
