I Hear the Immortal Venerable's Disciple Has Fallen to the Demonic Path Again?

Su Yi was a flower. Before he could cultivate into human form, someone picked him. Not only did that person show no remorse, he even had the nerve to insist on becoming Su Yi's master. With no other choice, Su Yi accepted. What else could he do, ask the man to plant him back in the ground? But the bargain master he'd picked up by the roadside died not long afterward. The whole "deeply devoted master and disciple, if you die, I won't go on living" routine was obviously out of the question. Su Yi was sad for a little while, then went on living his life in carefree comfort. As it happened, he found his bargain master's reincarnation. Fine. You raised me until I took human form, and I'll raise you until you're grown. Then we owe each other nothing. What Su Yi hadn't expected was that his bargain disciple seemed to have hurt his brain. He was extremely keen on playing little games of split personality. >>>>>>> Mu Yanyu was gifted and clever, with extraordinary natural talent. A cultivation prodigy the likes of which appeared only once in a century. Yet his beautiful master always said, "Slow-witted, heartless, nothing like a certain someone." Mu Yanyu: ? So Master only sees me as a replacement?! To prove that his master cared about him most, Mu Yanyu, the disciple who just had to court death, took inspiration from a famous cultivation-world story. He fell to the demonic path, then obediently waited for his master to lose his composure, reflect on his actions, and urge him to return to the right path. But Mu Yanyu waited until he was nearly a Demon Lord and still didn't see his master. No matter. If it didn't work once, he'd just try again under a different secret identity. He refused to believe his master wouldn't feel even a little sad! Su Yi: ...Did this guy hurt his brain when he was reincarnated? *A Cultivation (?): A Guide* 1.
