[Mindless wish fulfillment] + [Transmigrating through different worlds] + [No female lead] + [A little dark] + [Please go easy on me]

After Wang Yan dies, he is selected by the Space-Time Administration and chooses to travel to different worlds to complete missions.

Each time he arrives in a world, he receives a new System.

When he transmigrates to the world of Giants, Wang Yan gains the God-Tier Monster Creation System. To take down JRD and destroy the world, he keeps creating monsters and spreading panic.

When he transmigrates to a wasteland world, he stops acting human and becomes a villain, slaughtering people in the apocalypse.

When he transmigrates to the world of Cursecraft, he begins encountering all kinds of ancient legends and terrifying entities, using cursecraft to battle others in a contest of curses.
