The System Mistook Me for Cultivating Immortality

When Lin Muyu woke up, he found that he had time-traveled into a bad immortality novel and was bound to an unreliable mushroom system. The system told him that his mission was to play the role of a ruthless master, help the genius apprentice Chen Mian ascend to immortality, and rewrite the BE ending of the original work. However, the development of things completely exceeded his expectation—— Something is wrong with his apprentice: Chen Mian was not only reborn as a black man, but also had the demon soul sealed inside his body. On the surface, he was obedient and obedient, but behind his back, he always looked at him with wet eyes, and acted coquettishly and pretended to be pitiful, leaving him, a straight male master, at a loss. The system is divided: the mushroom system urges him to follow the plot during the day, but at night it splits into two voices. One coldly asks him to kill his apprentice according to the development of the original work, and the other desperately encourages him to save people, and even secretly stuffs him with love strategies. The plot collapsed: the original heroine Zhou Lianying was supposed to develop a relationship with Chen Mian, but as a result, not only did she have no interest in her apprentice, but she also fell in love with his medicine cultivator friend Xiang Yang. What's worse is that Chen Mian's attitude towards him is getting more and more strange—— "Master, if you don't like men," the young man pressed him against the bookshelf of the sword pavilion, and gently rubbed the new golden plum mark behind his ear with his fingertips, his voice was low and hoarse, "do you like the reincarnation of the Demon Lord?" Lin Muyu: "......???" ? We agreed to change our fate against fate, but why did we change it to a master-disciple relationship? ! ?

Two female protagonists and sub-CPs: free and unrestrained Fu Xiu Zhou Lianying × gentle and restrained medicine Xiu Xiangyang, a strong showdown Famous scene warning: On the first day of Master's time travel, his OOC character design collapsed, he fell into the medicine garden in public, and was punished by the system for singing "The Most Dazzling National Style" The apprentice was seriously injured and fell into coma, and the master was forced to "transfer the soul to the acupoint". The two of them were disheveled and were bumped into by the heroine. After Chen Mian turned black, he imprisoned the master in the cave and tied him to the bed with an immortal rope: "Master, don't you like to imprison me the most? I will imprison you this time." The system played the CP mixed cut of "Why is Master Like That" late at night, and Lin Muyu died on the spot This is not a simple article about cultivating immortals. It involves a lot. The system has a strong sense of existence and integrates many elements. It belongs to the author's imagination.
