Nanling is an old monster who has lost his precious inner elixir, and Wu Wei is a cowardly young man who has acquired the old monster's precious inner elixir, and may die at any time. Once he dies, the old monster's precious inner elixir will also be destroyed. In order to get back the precious inner elixir, Nanling must let Wu Wei live well before one year of Yangshou is exhausted. So she came to Wu Mansion and became a maid to a mortal. Rather than saying it was a maid, it would be more accurate to say it was a bodyguard.
Nanling really disliked his master, who was timid, thin, and not very smart, as well as that cowardly Brother Zhang. Alas, mortals are really in trouble.
It was finally time to retrieve the precious inner elixir, but Nanling's heart...
