After I Transmigrated into a Book, I Became the Master Even Dogs Wouldn't Serve

[Transmigrate into a Book + Female Teacher and Male Student at First + Inner Thoughts + Unconventional Cultivation Novel + Both Leads Are Virgins] [Lazy, sharp-tongued, lustful master × A jealous, flirtatious disciple who turns into a sniveling mess in front of his master] Everyone knows being a master is a dangerous profession. At best, your disciple will betray you. At worst, you'll be wiped out to the last ancestor. Unfortunately, Bei Xuechen transmigrated into a book and became the male lead's master, a character even dogs would shake their heads at. In the original story, the villainous master was skinned alive, had her tendons ripped out, and was ground to dust. To stay alive, Bei Xuechen became a gentle master and spent over a decade raising her little disciple. And then... She died! To stay alive, she became a villainous master and beat him until her hands hurt. And then... She died again! To stay alive... No! To enjoy herself before she died, she decided to let loose. She liked looking at handsome men, so why not enjoy them all? Then she realized her rebellious disciple had changed. He was sniveling all day long. What's it like to lose one soul and three hun? Weak!!! Too weak to handle tonics! Out of breath every few steps, coughing blood every third step. She'd thought returning to the cultivation world would finally let her enjoy life, but her disciple had become an Immortal Venerable who never showed his face and had even cultivated the Heartless Dao. She runs, he chases, and together they live happily ever after! [Content warning] The male lead has yandere tendencies. He's always threatening to die or making a scene.
