Cheng Yang was originally an ordinary takeaway boy. When he was 20 years old, due to an unexpected food delivery accident, he awakened the "underworld vision" inherited by his family and was able to see and interact with spirits. After being forced to inherit the ancestral "Yin Yang Office", he delivered food during the day and dealt with various supernatural incidents at night, becoming an agent connecting the Yin and Yang worlds. As his abilities increase, he finds himself involved in a huge vortex involving thousands of years of political struggle in the underworld and power games in the Yang world. He must grow up quickly to protect the living and the dead he cares about.
