Qingzhou City Funeral Home is a hidden passage between the worlds of yin and yang. Lin Mo, its night watchman, was born with Yin-Yang Eyes that let him see through evil spirits. He also possesses a pure-yang constitution and inherited his grandfather's secret arts and demon-suppressing System. After his grandfather's death, Lin Mo is an unremarkable deliveryman by day and a demon-suppressor by night, facing one bizarre unsolved case after another.
The red-clad apparition in a century-old haunted house, the deranged bride cursed by a marriage demon, the water ghost that claims lives beneath the river, the missing corpses from a hospital morgue... Each case is riddled with suspicious clues. They seem unrelated, yet all bear traces of the mysterious evil cultivator sect known as the Yinluo Cult.
As the layers of mystery are peeled back, Lin Mo discovers that his parents were killed for stumbling upon the Yinluo Cult's "Gathering Yang Plan," and that the curse on his fate has made him the central sacrificial offering in the evil cultivators' refinement of a sinister pill.
To avenge his family's blood feud and protect the peace, Lin Mo tames spirit pets, forges alliances, unlocks secret arts with merit points, wipes out the evil cultivators' strongholds, and confronts the cult leader's ultimate plot. From an inexperienced night watchman to a revered demon-suppressor who commands the forces of yin and yang, he uses his pure-yang constitution to break every sinister scheme under heaven and writes a suspense-packed legend of subduing evil across the realms of yin and yang.
