This was the sincere advice of the cultivators to Gu Qing Shan before they left.

At some point, it began to rain and gradually turned into a heavy downpour.
In the wilderness, large quantities of rainwater washed through the ruined walls and structures.
After some observation, Gu Qing Shan noticed that these structures were all created from some especially tough material, some of which still radiated a unique power fluctuation.
