She is the phoenix of nirvana, and he is the dragon of reincarnation.
Thousands of years ago, he lost his soul to protect her; ten thousand years later, she returned with her memories, but he had become the regent who had forgotten his past.
She used her mortal body to fight every step of the way, just to awaken his sleeping soul.
When he remembered everything, he realized that every time she approached her, it was a sacrifice of her life.
This time, it was up to him to change his destiny.
