She is a thousand-year-old flower spirit on the other side of the Wangchuan River. She is on the bridge of Naihe, crossing people's reincarnations.
He is a divine king in the ninth level of heaven. He was born without any love strings. He descended to earth and endured calamities, but still has long love strings.
The flower spirit in the underworld and the god of war in the heaven are very different from each other, but because the little flower spirit "frivolous" the god king, they have been tied together ever since.
You go through calamities, and I will follow you. You go through three lives, and I will follow you for three lives.
From then on, love grew only for her.
