1 Becoming stronger to Dominate all worlds

Leveling world a world where you level up your character. Level decides everything in this world the higher your level is the stronger you are but there are some people that are stronger even if they are low level. In order to level up you need to kill monsters like goblins , slimes , and more. There are many world's out there but the humans don't know about them yet because only when you hit the max level which is level 1000 will you be able to exceed the max limit of the worlds level and go to the higher world which is 10x bigger and dangerous world by evolving yourself once you evolve, your level will be reset but you get a boost of the experience you get by killing monsters permanently by 1000x and the same goes for your strength each time you evolve it will multiply it again by 1000x from your current boost.
