Writing Quality = Good
Stability Updare = Really Good
But as for the rest.. Bad...
Paragon of destruction = Paragon of average
First point, MC doesn't seem to be logical at all, he threw golden opportunity to train just because he want to find a shortcut (that doesnt exist) or can't handle the training.
Second point, MC does stupid logical decision even if the best answer/solution is slapped at his face, he goes full retard because of plot (?)
Third point, the MC is AVERAGE, he doesnt have any talent whatsoever; what he has is the forbidden real, that from what is shown is not even that 'legendary', an example of a (my imaginary) scale:
Common - Rare - Rare+ - Epic - Legendary
The forbidden realm is only at Rare, or at max between Rare and Rare+
But the worst point is that 'this advantage' that he has on the forbidden realm IS USELESS; he has a forbidden realm that is only mentioned at the start of the novel and during chapter 50 from what I understood, and nothing. We know nothing about the forbidden realm, what it is exactly, what type it is, NOTHING, he doesn even use it; and we are already 100+ chapters in.
