Su Tang accidentally drinks the blood of a vampire lord and, as a newborn vampire, travels into various worlds with the mission to heal and save the blackened antagonists. [Paper Lover] Transmigrating as the paper lover of an antagonist CEO, he is pampered and spoiled by the CEO’s lavish spending, only to later sneak out of the phone, rolling playfully in the CEO’s palm, peeking at the scenery from his pocket, and eventually returning to normal size—only to tumble right into the antagonist’s bathtub. [The Tyrant’s Empress] Replacing the legitimate son of a noble family, he is delivered to the tyrant’s bed as a medicinal offering. While others expect him to die, not only does he survive, he becomes the most favored empress in the realm. [Little Kitten] Transformed into an abandoned cat, he is taken home by a post-apocalyptic big shot. While others fight zombies, he happily indulges in food and drink, growing from an adorable orange tabby into a plump chicken drumstick.
