Incense Becomes a God: Starting with a Demon Lamp

After guarding the old temple of the dead mountain god for nine years, I only had one lamp. When the lamp lights up, demons and ghosts appear; when the lamp goes out, I am destined to return to the west. Incense is lamp oil, and solving cases is practice. Every time a light is extinguished in the world, my light becomes brighter. Later they called me: Lamplighter.
