@Lexical i am pretty sure D&D stop at level 20 and grey ooze are pretty dangerous (i don't know if you get xp is you are level 19 and kill a level 1 trash mob)
@Kyujyu well no because human are not the only race and dragon of demon already over a 1000 years but way under level in comparison of the MC who did only xp without trying for "only" 600 years (300y + double xp) i want to really point out she did not even try to level up
now i also want to question the pretty simple fact any player know, well a large dragon that give 2500xp, do the xp you give at death in this world do not increase as the level go up ?
no because if you beat the ultimate dragon that is level 99 and gain as much as a baby dragon level 1
Actually i am interested in the subject don't take this as a critique of the manga but just curiosity how the world work
