In this urban suspenseful revenge novel, Su Wan, a thousand-year-old female ghost, travels back in time to become the victim of a wife-killing case, uses ghostly means to punish the scumbag, and transforms into a "female revenge agent", setting off a hearty storm of justice in the shadows of the city.
Purpose: Real power is not used to dominate, but to protect; the most powerful revenge is to let the perpetrators be swallowed by their own sins, while igniting the fire of hope for the silent ones.
