Who is Runyu, the night god born with the Emperor of Heaven? Why does Tianhou hate him?

He is the princess of Taihu Arowana, the fairy and the son of Emperor Tian. Because Su Li looks a bit like the first flower god, and she is just the god of heaven looking for the shadow and sustenance of the first flower god in herself. When I bid farewell to Tianhou, I was regarded by Tianhou as a fire bead given by the Emperor of Heaven. The most precious fire beads in heaven are only two strings, one of which was given to Tianhou when she married Tianhou. Another string originally belonged to the Emperor of Heaven, but now it is worn on Su Li's wrist. Tianhou immediately understood what had happened and laid a curse for the future. Tianhou loves heaven and earth very much, but heaven and earth like flower gods. She's jealous and annoying. Naturally, even the shadow of the flower god is not immune. And killing arowana can also play the power of water god. Tianhou naturally hates her and wants to kill her.
