Li Yunxiao accidentally transmigrates into a period fantasy cultivation drama. But to his dismay, he doesn't become the protagonist. Instead, he becomes a cannon-fodder member of the Demon Sect who is destined to die in the very first episode. Facing the executioner's raised blade, Li Yunxiao activates the God-Tier Script System. By editing the subtitles in the script, he can change the storyline. Not only does he escape danger, but he also gains unexpected abilities. This perilous world of immortal cultivation becomes a whole lot more entertaining thanks to this miraculous system.
