I Just Became a Heavenly Master, and the Supernatural Bureau Invited Me to Enter the Ghost Realm.

When I was eight years old, a coal mine collapsed and I became a fool. My rich father sent me to the Half-Immortal King Sixi for Liu Jiafeng. Ten years later, I inherited the Celestial Master system. Although I inherited the Celestial Master system, it had no effect at all. I needed to eliminate the Yin evil to activate the system, which made me terrified. Fortunately, I had studied Celestial Master for ten years, and the system could be upgraded as long as the Yin evil was eliminated. Unexpectedly, when I cast the spell for the first time, I encountered a surge of Yin Qi. I shouted: "Monster, show yourself quickly!" This novel and its characters are purely fictitious.
