Ye Linfeng, an ordinary courier boy, shuttles through the city streets every day. Who could have expected that a mysterious test would completely overturn his life trajectory, and he would enter the mysterious world of Yin and Yang postmen.
With the blessing of the heaven-defying system, Ye Linfeng awakened the astonishing lifespan vision and could see through life and death at a glance. The book of life and death seems transparent in his eyes, and he can wander between the yin and yang realms.
In the world of the sun, he delivers express mail as usual; in the world of the underworld, he conveys obsessions to the souls of the dead. Relying on the life-span energy he absorbed, he can counterattack in desperate situations. In a moment of life and death, he can not only turn it into a magical power to extend his own life, but also can pour out all his energy in times of crisis to save others on the verge of death.
Let's see how this courier who holds the key to the Yin and Yang world writes legends in the bizarre worlds of Yin and Yang, embarks on a path to godhood that shakes the three worlds, and changes the world for him!
