I’m a Succubus, and They’ve Set Their Sights on Me

[Female lead pursues male lead + matriarchal society + yandere + part fantasy + transmigration] “Master, I was betrothed to someone when I was young, and now...” “Silence! You're the eldest senior brother of the Demon Sect, handsome and talented. Who could possibly be good enough for you? I order you to break off the engagement at once!” Lin Yu looks at his beautiful master, bewildered. He's only going to honor his engagement, so why is she angry? “Master, I want to train in the Land of Life and Death and improve my strength.” “Yu'er, you mustn't. It's extremely dangerous there. But I do have a way to improve your strength, one that only requires the two of us, master and disciple, to work together.” “Master, you know a method like that? Tell me.” Ever since she forced that child to become her disciple, Yan Ruyun hasn't realized that she spends every day wanting to cling to her sweet, well-behaved little apprentice. She's practically a disciple addict. “Good Yu'er, let your master help you cultivate~” “Good Yu'er, let your master wipe your hands~” “Good Yu'er, come here and tend to your master's wounds~” (My ambition is to write the most disgusting book ever!!!)
