At the end of his rope, Lin Mo signed a life-and-death contract to save his parents and became a midnight courier.
His recipient is never a living person!
The ghost with embroidered shoes in the abandoned teaching building, the dead hands in the mass graves, the headless corpse at the bottom of the river surrounding the city, the soul of the drowned in the ward...
Every order is a yin and yang situation, and every delivery is a test of life and death!
When the four souls gathered together and old secrets were revealed, he discovered that from the moment he joined the company, he had fallen into a shocking conspiracy that spanned Yin and Yang.
As a courier from the underworld, he travels between the realms of yin and yang, delivering obsessive parcels, guarding the vitality of the world, and breaking through the dangers of the underworld!
Once this Yinsi express is on the road, it will never return!
