Acting Judge of the Yin and Yang Realm

The left hand holds the book of life and death, and the right hand holds the judge's pen, which determines yin and yang and determines life and death. Everything started when my grandfather died for no reason. Through a series of strange incidents, I learned about my grandfather's other identity. From then on, I became an acting judge and embarked on a life journey to find the real culprit who killed my grandfather.
