After death, Shen Yuan found himself in a supernatural martial arts novel that he deemed as trash just before his passing. The usual expectation was for him to be reincarnated as the protagonist, but that was far from what happened. Instead, he transmigrated into the body of Shen Qingqiu - the novel's infamous "scum villain." In the novel, Shen Qingqiu was a cruel teacher to the protagonist, Luo Binghe, resulting in his gruesome fate at Luo Binghe's hands. Determined to steer clear of that destiny, Shen Yuan exploits his knowledge of the novel's plot and clichés to win the favor of the characters, most notably the protagonist. However, his task is complicated by a System that grades his every move, restricting his behavior and dictating the story's trajectory. Ignoring the warnings could be fatal, and so Shen Yuan embarks on his journey into the world of cultivation, with no room for error.
