After coming to this strange world, Jing Meng regarded Ning Changan as his only support. Together they caught monsters and rescued people, and they were very happy.
Later, Jing Meng watched helplessly as he fell in love with someone else and left himself behind for that woman.
She wanted to leave, but this world was completely unfamiliar to her. Where could she go without him?
It wasn't until Ning Chang'an became a demon, she fed the demon with her body, and her body died, that the relationship between them was severed.
Many years later, in order to save his lover, Jing Meng met Ning Changan again, only to find that his hair had turned gray overnight and his practice had stagnated.
Ning Changan: Ameng, would you like to stay? Everything before was not what I wanted.
Jing Meng: This time I'm here to ask for medicine. If I have enough time, I'll also seek revenge.
Changsheng: Ameng, wherever you are from now on, I will be there.
Concept: Love is a one-way street, you can only move forward, never backward.
