"Heaven erased me from its records, but forgot to take back this brush. My name is Li Yun. After descending to the mortal world, I started delivering takeout. Help someone, and a golden mark appears on the brush; harbor an evil thought, and another black line appears. I thought I was just a celestial copyist who'd been erased, until the day I touched a vengeful spirit with it and saw the one character even Heaven dared not write. From that day on, I delivered takeout while fighting vengeful spirits with gas canisters and electrical boxes, and investigating who erased me."
