Capítulo 650: Chapter 340: Spatial Magic Crystal_3

The formation of magic crystals requires the condensation of a large amount of elements under specific conditions.

Generally speaking, magic crystal mines are formed when a World Calamity is imminent. When a World Calamity occurs, the entire environment of the world undergoes a drastic change, with certain areas experiencing constant volcanic eruptions, or enduring gales daily. Under such conditions, most living beings find it impossible to survive. Ninety-nine percent of all living beings die in the catastrophe. It is for this reason that the civilizations of previous epochs have been destroyed by these Heaven and Earth Catastrophes.

However, during the process of such a catastrophe, although living beings are unable to survive, it is a period of rest and recuperation for the world itself.
