Yin has Yin rules, Yang has Yang laws, and the Yin and Yang Order Bureau is the existence that controls the balance between the two realms and resolves the obsession of the dead souls.
Lin Wei, a former drug police officer, accidentally returned to the underworld and became an underworld policeman, forming a happy partnership with Gu Qingyuan, an old scholar from the late Qing Dynasty.
They traveled between the Yin and Yang realms, investigating the obsessions of the dead souls. Cross-life concerns, unfinished agreements, and misunderstood affections have all become shackles that trap the dead souls.
There is no cool fighting against monsters, no bloody love, only tenderness and regret that are so delicate that it hurts your heart.
Lin Wei went from mechanically enforcing rules to understanding the love and hate behind every obsession; Gu Qingyuan went from being pedantic and old-fashioned to being softened by the warmth of the world. While bickering with each other, the two cleared away the fog, unlocked the truth behind the obsession of the dead souls, and saved the souls of the dead, as well as themselves.
Yin and Yang are separated, but love never ends; obsession is the guide, gentleness is the transition. ——Every stranded soul is waiting for a late reconciliation.
