Destroy the World Starting from Douluo

"Hello time traveler, I am your system." "Ah, what's the use of this?" "Destroy the world." "Uh, can you do something else?" "Destroy other worlds." "Mdzz, don't do it." "It allows you to stand at the top of the world and control everyone's life and death." "Not interested." "You can travel around without having to work." "It's done, hurry up!" Ps: Dark direction, the kind of huge darkness.
