This novel consists of two stories, the first one is "The Love of Demons and Gods" and the second one is "The Story of Zhu Yan". The two stories can be regarded as two independent stories. In addition, this novel is a fragmented story, and the independent plot fragments have great jumps. I hope you will know more about it.
In the previous article, "The Love of Demons and Gods", the divine realm lives in legends. Gods cannot descend to the lower realms, let alone be emotional, and cannot interfere in the cause and effect of the mortal world. The God of Fire, who turned a demon into a god, is disgusted with it, and cannot bear to accept that it is natural for humans to kill demons and obtain elixirs. He escapes from the lower realms many times and has a "forbidden love" with the sea god Shui Yan.
In the next chapter, "The Legend of Zhu Yan", a long, long time later, the God Realm still lives in the legend, the demon clan retreats, and the human race with high cultivation and long lifespan create their own fairy world, and the underworld, which was originally parallel to the God Realm, is partially exposed for balance. Zhu Yan, the god of war in the underworld, accepted Yun Shiyan, a disciple from the immortal clan, and taught him great love. There is no cp between the male and female protagonists in this article, it is a master-student relationship.
Concept: balance between demons and gods, big love and little love
