This article is the original work of Lord of Mysteries written to Hongyin CP. The background of the original work from the second to the fifth era has a lot of personal imagination. I will try my best to restore the original background and timeline. Please forgive me if I can't remember Amon or OOC. It is privately designed that Xiaohong first appears as an angel in sequence, and Orochi is the king of angels.
