From the beginning of the development of every world, there is a certain "first driving force". This force flows infinitely and is interlocked, thus creating diverse and infinite things.
The world is still moving since the development of the world. The emergence of existences like human beings with "souls" is the inevitable stage when the movement of world power reaches a node. The birth of the soul also originates from the derivation of the first driving force, which differentiates and spreads and becomes parasitic in all things.
As a soul, Wen Yin's cultivation is also the "driving force" of this world. She needs to show her soul and put it into the pulse of the world to be immersed and cultivated.
This is similar to a mother placing her child in a nursery. When she puts her child in, she must have the permission of the world, and when she takes her out, she must also get the acquiescence of the world. The premise of this "tacit approval" is Wen Yin's promise to the world - to sincerely abide by the laws of operation of this world.
She must pretend to be an ordinary person, do more good deeds and avoid evil deeds.
As a wandering soul, Wen Yin doesn't know where her mission lies.
Purpose: I wish all lovers in the world to get married eventually
