My Entire Family Is Full of Mad Villains, but My Master Is the Only One Who Keeps His Cool

[Transmigrate into a book and cultivate immortality + female lead with no romance + goofy, laid-back lie-flat lifestyle] A single working woman transmigrates into a cultivation novel and becomes the male lead's master, the Immortal Lord Jiuli. She saves the male lead when he's on the brink of death, changing her own future fate of being killed by him. Jiuli wants nothing more than to stay away from the male lead and all the trouble, living a carefree life. Instead, she takes in a whole group of obsessive, villainous disciples. With no choice, she declares, "Fine. Work hard at your cultivation and become the strongest. Your master is going to lie flat."
