In the vast wilderness, the dynasty city maintains the fireworks of the world; the mountain gates such as Baishi Jianzong occupy the spiritual veins and are in charge of spiritual practice; the Tianmen that hangs high in all realms is in charge of the priesthood, reincarnation and heaven.
In this world, names are not simply titles. Household registration determines whether a person can receive food, travel through the city, and be buried. Sacrifice determines whether the deceased is still remembered. The reincarnation book records the birth and death of all living beings. Some people believe that deleting unstable names can bring lasting peace to the world.
The ancient war between gods and demons has long since faded into the past, but the remains, broken swords, old laws and unexplained sword marks are still buried in the wild mountains and rivers, military orders in border towns and ancient mountain gate scrolls. Mortals and monks, demon clans and dynasties, mountain gates and heavenly gates all live under the same order, and they all bear the price it leaves behind.
The story begins with an iron shop, a bowl of salt tea and a beast tide on the north wall. Shen Li, a young man from an iron shop, got an unknown broken sword, but Ahe, an orphan from the border town, had no recorded name. As tampered military orders, out-of-control ferocious beasts and ancient echoes appear in the broken sword, an old mystery about names, reincarnation and the choices of living beings gradually comes to light.
Shen Li and his law-enforcement disciple Jiang Zhaoxue will go from the border city of the human world to the sects, dynasties, demon clan border gates and the heavenly gate of the fairy world. Between the wild mountains and rivers and the fireworks of the city, they ask a question: Who is qualified to decide who should be remembered and who can be erased?
