A Miao was once the most inconspicuous low-ranking soul-reaping ghost in the Underworld. For a thousand years, she kept her head down, collecting only the stray souls along the River of Forgetfulness, obeying the rules and avoiding trouble.
A secret attack by the Heavenly Dao tears open the space of the netherworld. Her spirit falls into the mortal realm and possesses Su Miao, an oppressed concubine-born daughter of the Su family in Great Jing.
Her body is frail and she has no one to rely on, making her an easy target for everyone in the household. Her stepmother mistreats her and withholds her allowance, her half-sister feigns kindness while poisoning her, and her relatives treat her as a bargaining chip, forcing her to marry a minister in his sixties to buy their way into power.
Everyone thinks she is meek and easy to bully, unaware that within her frail body dwells a spirit that has seen every kind of wicked ghost in the Nine Hells.
Born with yin eyes, she can see the good and evil in people's hearts and glimpse their karmic debts and coming misfortunes. Her body can suppress spirits, keeping evil entities at bay, while anyone who approaches with ill intent is struck back by yin energy.
She stays true to herself and never harms anyone of her own accord, only defending herself when necessary. All those who do evil bring their misfortune upon themselves, as karma runs its course.
No one could have guessed that the unseen force repeatedly smoothing over her troubles and clearing away danger was no mere coincidence.
The mysterious scholar in black, living in seclusion, is none other than Emperor Yuancheng of the Netherworld, ruler of the Six Paths of Reincarnation.
A Miao is a chaotic yin spirit he has carefully nurtured for a thousand years. This transmigration was a deadly trap laid by the enemies of the Three Realms.
In public, she is a powerless orphan anyone can bully. In private, all the ghosts bow before her, while the supreme ruler of the Three Realms silently shields her from harm.
She neither seeks conflict in the mortal world nor fears the wolves of society.
Even when the mortal world is swept by storms, she has a supreme protector at her back, keeping her safe and secure for life.
