Speaking of which, the classification of superpower users and monsters is actually quite strange.
There are only five levels in total, with the fifth level being elusive, and in fact, there is little difference between the first and second levels.
Such categorization would be better described as the five stages of continuous evolution for superpower users, rather than based on strength.
The fifth level, Calamity Level or the Transcendent Boundary, represents beings that surpass both superpower users and monsters, even transcending the concept of deities and demons found in traditional mythology.
Their power limit is unimaginable for superpower users; their existence goes beyond human comprehension. To this day, there has been no case where someone has witnessed such a level of existence and lived to tell the tale.
