Achieve the Kingdom of Death in All Realms

This is a cool story about accidentally picking up fragments of the God of Death and traveling through various worlds to collect talents and treasures. "Oh, why are you lying on the ground, kid? Your body is already cold. Why don't you turn into my heroic spirit?" "Oops, whose protagonist is lying on the ground? We can't waste it, let's give it a shot." "Oh, another little cutie, eh? There's also a villain here? Well, they're both pretty. I want them all." This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
