It's My Birthday. My Nine-Yang Magic Is Specially Designed to Defeat Evil Spirits.

The spiritual energy revived and strangeness raged. Su Mo, a college student, was targeted by a murderous love letter ghost. He accidentally awakened the system and learned the nine-yang sky-swallowing magic skill to kill the monster. He actively hunted weirdos to earn merit, strengthened his magical skills, and was recruited into the establishment of Bureau 749. From then on, Su Mo worked his way up the ranks, met Lin Xianxian, subdued the old Taoist priests, solved the unfinished building, the Zhou family's haunted house, the corpse coffin and other mysterious cases one after another, and formed a deadly feud with the evil cultivator Li Wuxie. In the end, Li Wuxie colluded with the treacherous world to open the door, and Su Mo used the power of Nine Suns to turn the tide, kill the treacherous realm, and protect the world.
