After Raising a Yandere, My Arrogant Master Went on a Killing Spree

[A cool, proud master and her dark, obsessive disciple] Lin Wanyue transmigrates into a cultivation novel as the cannon-fodder master who abuses the male lead and eventually dies without a whole corpse. When she arrives, the original owner is holding a whip, about to lash the future villain, Gu Ci, who will one day destroy the world. Looking at the battered boy with his sinister gaze, Lin Wanyue's heart trembles. To save her own life, she throws away the whip and pulls a piece of candy from her robes. "Good disciple, your master bought you this candy."

The boy's eyes change.

Gu Ci is cursed with misfortune and has endured the world's scorn all his life. He thought this lofty master would torment him until he died. But later, she takes a sword for him, searches for medicine for him, and stands against the entire cultivation world for his sake.

Good disciple? Treating him like her own? Hah.

How could he be content with being only her disciple?

Long, long afterward, Gu Ci reaches the pinnacle of the cultivation world and becomes a Demon Venerable feared by all. Lin Wanyue trembles as the man steadily closes in. "You rebellious disciple, what are you doing?"

Gu Ci smiles wickedly and pins her against the wall. "Didn't Master say you cared for your disciples more than anything? Then care for me all the way."

Lin Wanyue: "...Can I still expel you from the sect?"
