During the battle between immortals and demons, the god Xiyun used up his spiritual power to seal the passage to the three realms and turned it into stars all over the sky.
A soul was reincarnated as a mortal Ye Yiling. She was the only daughter of the General's Palace in the capital. She was loved by everyone since she was a child. However, her mother died during childbirth. In order to find her mother, the heroine went to Yueqi Mountain to cultivate immortality and became the only disciple of the hero.
The master is cold and ascetic, respected by the three worlds, but he only loves the heroine to an extreme.
It wasn't until a certain calamity when the star core awakened that he was shocked to realize:
The little disciple he held in his hand was actually the fallen god Xiyun!
Purpose: Gods come down to earth to worship their masters, seek their mother, and return to their throne after nirvana.
