Chapter 133: Reinforcing
A bear has three main evolutionary phases.
Before the first evolution, when they are below Level 30, they are termed as Lesser Bears.
After the first evolution, the bears in the level range of 30 to 50 are termed as Intermediate Bears.
The second evolution takes place when they reach Level 50 and thus, after that, any bear before the third evolution, that is, below Level 80 is known as Greater Bear.
The final evolution takes place at Level 80 and thus, a Greater Bear Evolves into a Chaos Bear.
The bear king is at this Chaos Bear stage, which is quite a terrifying stage apparently.
Kira was specifically worried about this stage after all; from the legends, it's evident that a level 80 Chaos Bear can match the strength of a Level 100 Supreme Bear, at least for a few seconds - and this alone is the most terrifying thing.
The leveling system in this world is limited like any other.
