Reborn as a Demon, I Turn the Tables by Possessing Others

[System-powered wish fulfillment + not mindless + sensible growth + hilarious + passionate + scheming + bizarre]

After a thousand years, the goose clan's useless egg finally hatches. The soul of an Earthling, Duan Beicang, arrives through transmigration with two demonic weapons and becomes a little monster.

He is utterly baffled...

I want to be human!

He activates the strongest Demon-Eating System and wields the Dragon-Devouring Art, devouring monsters and treasures alike.

He possesses a human, breaks free of his beastly body, and begins a hilarious rise to success.

This is the story of an Earthling who steadily develops in another world, builds up his strength, and eventually becomes a giant of his age.
