Twenty thousand years ago, the Mirror of the Realm that maintained the order of the Three Realms was shattered and the fragments scattered in the world.
Immortals do not come to the world, and demons do not enter the world. Under the eternal law, no one dares to cross the boundary to look for the mirror——

If you go to the human world, your life span will be like that of a mortal, and you will never be able to return.
She walked through thousands of mountains and rivers, picking up piece after piece.

Intention: destiny and autonomy
