My Ascetic Master Can't Escape the Sevenfold Love of His Substitute Disciple

[Two male leads + transmigrate into a book + substitute + younger man + devoted to each other + yandere + pure love] [Arrogant, confident master, the uke x younger, useless disciple, the seme] After being stabbed to death, Rong Jiuxiao transmigrates into the book as its strongest cultivator. The original character had collected five substitutes, and the male lead was one of them. The System tells him to follow the plot. Rong Jiuxiao refuses on the spot: Don't even ask me, I hate men! So the System explodes! He kills the male lead's father! - That day, Duan Baiyou found the only light in his world and wanted to become the strongest man's one and only disciple. Rong Jiuxiao not only tricked him into cultivating the emotionless path, but also began a Platonic romance with him. Later, sitting by the bed, Duan Baiyou smiled darkly. “Master, you haven't been good. Why did you smile at someone else today instead of me? I should slaughter their entire family, so you'll belong to me alone!” Rong Jiuxiao was stunned. “Little darling, I'm a full ten years older than you. We can never be together. This is a twisted kind of love!” That night, Duan Baiyou was expelled from the sect. To Rong Jiuxiao's surprise, the disciple, his face red with anger, climbed back in. “Master abandoned me. This little one is heartbroken!” Rong Jiuxiao forgave him once, never realizing that the wicked disciple was thinking that his master was merciful and righteous to a fault. If he lost all his cultivation and became a peerless cultivation furnace, could he still remain so emotionless and loveless?
