Ever since the use of nuclear and chemical weapons, organisms on this planet have been continuously mutating. Mutant creatures seem to be evolving towards becoming more and more ferocious. In contrast, humans not only find it increasingly rare to awaken superpowers, but cultivating them has also become difficult and slow. Even the birth rate has significantly decreased, making natural procreation exceptionally difficult!
When low-level superpower users advance, it's still somewhat manageable. However, the higher the level, the harder and more dangerous the advancement becomes! Unlucky ones may even have their meridians burst from the energy surge during advancement! Even worse are those who are on the verge of succeeding, only to have their bodies fail to endure the intensified processes, ultimately failing to advance and becoming crippled!
