In the second era after the creation of the world, there was a war between gods and demons, and the gods fell. The Father of All Things sealed the power to open the third heaven in the remaining bloodline of the gods.
Decades later, Mu Li, a descendant of the dragon clan, found the remaining bloodline of God Father and opened the third heaven. Only then did the world restore a new order.
Lu Wanwan, a spirit that travels between the mortal world and the underworld, records the memories of mortals before their death, but she can never remember her own past.
Qin Jiu, a descendant of the Xuan clan, has a marriage contract with Lu Wanwan. Even if he cannot get close, he is willing to protect her from a distance.
