I Became a Saint by Slaying Demons in the Demon-Slaying Bureau

Transmigrator Lu Jiuyuan joins the Great Xia Demon-Slaying Bureau and binds to a Demon-Slaying and Monster-Eating System. With system support, he learns cultivation techniques, uses lightning and fire to slay a thousand-year tree demon, and outwits the plans of the Red Lotus Sect. From a new recruit to a hero, he faces crises like paper puppets, illusory paintings, and evil fetuses. Joining forces with comrades Xie Tian and Su Yuebai, he tears back the truth amidst supernatural chaos, wipes out four great guardians, cleans the Red Lotus Sect's stronghold, and rises from a chief flag to a hundred households, seizing local demon-slaying power. With a mortal body, he forges a legendary tale of slaying demons and becoming a saint.
