Nine Yang Defeats All Evil

With spiritual energy returning and eldritch horrors ravaging the world, college student Su Mo is targeted by a cursed love letter. After accidentally awakening a system, he masters the Nine Yang Divine Swallowing Technique and kills the monsters. He actively hunts eldritch beings to earn merit, strengthens his power, and joins the 749 Bureau. From then on, Su Mo upgrades while slaying horrors, meeting Lin Xianxian, subduing an old Taoist priest, and solving cases involving abandoned buildings, the Zhou family haunted house, and a coffin housing corpses. He falls out with the evil cultivator Li Wuxie. In the end, Li Wuxie colludes with the eldritch realm to open a gate. Su Mo uses his Nine Yang divine power to turn the tide, destroy all monsters, and protect humanity.
