After Transmigrating as a Wicked Master, I Got Tangled Up with My Villainous Disciple

[Female Lead Who Grows, Romance, Transmigrate into a Book, Happy Ending] Di Fuying transmigrates into a book as the infamous young sect master of the Xuantian Sword Sect, a thoroughly wicked woman who abused the villainous male lead as his master. She says she's not worried. She can just run away. But then a System suddenly appears and tells her to save the villainous male lead, who has been beaten half to death? You've got to be kidding! Di Fuying flatly refuses. She has no desire to save a male lead who's turned evil. The System can't do anything about it. Threats don't work, so it can only tempt her with a reward. Di Fuying: "What?! I get a golden finger that makes me immune to the male lead's attacks for the duration of the quest, as long as I complete 'Rescue the Male Lead from the Dungeon'?!" This golden finger... Ahem, this quest is just too good! She loves doing quests! Besides quests, Di Fuying also loves raising disciples. She's raised three of them. The other two turned out upright and proper, but why is this villainous male lead getting more and more wrong the longer she raises him? Especially the way he looks at her, like a starving wolf on the brink of death eyeing a tender, juicy piece of meat. In the dim, flickering candlelight, the man's eyes are full of obsession and sickness. "Master, look at me. Why can't you keep your eyes on me alone?" "It's all right. I'll lock you away, and then you'll belong to me alone." His voice is low, laced with a hint of pleading. "Master, tell me you love me." Di Fuying glares and kicks him off the bed in annoyance. "I told you, your master doesn't like old men or young boys." Ji Xianqing: "..." Oh no! He's both!!!
