In order to save his seriously ill father, Lin Zhou, a delivery boy who dropped out of school, became the most troubled part-time worker in the underworld's KPI.
During the day, he runs around in the world, earning dozens of dollars from a takeaway.
At night, he walks on the boundary between yin and yang, and one obsession changes his life to yang.
He has seen the unfulfilled filial piety of a programmer who died suddenly, held a child who could no longer be touched by a fire hero, and listened to an empty-nest old man talking nonsense to an AI video... He used his meager power to fulfill the unfinished wishes of the deceased souls and make up for the deep regrets of the world.
He thought that the end was to accumulate enough merit to extend his father's life.
Until his father passed away, he personally extradited his soul, but deep in the underworld, he found his mother who was trapped in eternal hell because of him.
It turns out that all this has been a redemption and conspiracy spanning life and death from the beginning.
From then on, the takeaway electric car drove to the underworld, and the judge's pen lit up the world.
Not only does he want to overcome all the obsessions in the world, but he also wants to reverse the chaos of Yin and Yang and seek justice from the rules of the underworld!
