Humans are fortunate to be carbon-based rather than silicon-based creatures, but unfortunately, most items made by humans are corroded by acid rain.
However, the acid rain created by the Bat Monsters can only be maintained within the coverage area of the Magic Capital Base, and the main purpose of the Bat Monsters creating acid rain is not to destroy the Magic Capital Base, but to detain the survivors at the Magic Capital Base, preventing them from recruiting while looting other areas.
Just as Dong Tianyu and the survivors living in the Magic Capital Base were hiding indoors waiting for the acid rain to end, the Bat Monster releasing the acid rain had already completed the sacrifice and obtained the coordinates of items containing a large amount of Plane Origin.
Currently on Blue Star, the items containing a large amount of Plane Origin are mostly Strange Creatures and Mysterious Cores.
