Slaying Evil in the Mysterious Heavens

Nian Xichen, the greatest demon slayer under heaven, transmigrated. She transmigrated to the vast river of worlds, where the uncanny was everywhere and corruption ran rampant. There, she was bound to a demon-slaying System with a Host survival rate of zero. Anyone else would have been crying and demanding to be unbound so they could run away. But Nian Xichen wasn't afraid. She fought her way through the corruption, tearing apart the uncanny worlds as she went. After all her smashing and wrecking, the demons and monsters across the myriad worlds realized one thing: a human had invaded and corrupted them in turn. Just hearing the name Nian Xichen made them twist, seethe in darkness, crawl, scream, weep, go mad, and tremble uncontrollably... Demon A: I'm a folklore-type demon. That demon slayer barged right in without even hearing the rules. She just started chopping at everything in sight! The uncanny world I spent every waking hour building was wrecked by her. Demon B: I'm a mutation-type demon. You know what that demon slayer said after she mutated, with five heads and ten arms? She said, “Thanks!” Having more arms made it easier to slay demons. Demon C: Which of you had it worse than me? I'm a desire-type demon, but that demon slayer's greatest desire is to slay demons. When I use my powers, she gets all fired up. The more I attack, the more fun she has cutting me down. With a crash, the door suddenly burst open. Nian Xichen rushed in and felled the demons with three swift sword strokes. The demons: You attacked us by surprise! Despicable! Shameless! If you've got the guts, let us go and fight us all at once! Nian Xichen: I refuse, for two reasons. First, I'm young. Second: 12346, 64321. The demons: What does that mean? Nian Xichen: Young people don't play by the five rules of honor. * Those who harm heaven and reason are demons. Those who commit evil are demons. Those steeped in wickedness are demons. Those blinded by desire are demons. The deluded, the greedy, the lustful, the wicked, the jealous, the foolish: I shall cut them all down with one sword. Demon-Slaying System: Aaaaaah! That's a human! What are you doing? Why did you slay them all? Nian Xichen said coldly, “If humans commit demonic acts, then they deserve to be slain even more!” * Reading Guide: 1. Lots of fight scenes. 2. The heroine is beautiful, cool, strong, ruthless, and sparing with her words. 3. These demons aren't the demon clans found in ordinary cultivation novels. They're uncanny creatures corrupted by pollution. Eating people is just a hobby; their instinct is to keep corrupting other creatures. * Main story arcs The Town of Sinful Spirits (complete) The Thousand-Year-Old Mansion (complete) The Seven Sorrows Academy (complete) The Age of Turmoil and Filth (complete) The Haunted Imperial Palace (complete) The Domain Lord Approaches (complete) The Desolate Island (complete) The Wandering Apartments (complete) The Reincarnation Battlefield (complete) The Immortal Path of Bones (complete) The Source of the Myriad Worlds (complete) Theme: Root out evil completely.
