Gu Weiyun has always adhered to the iron law that "immortals and demons do not coexist" as an iron rule throughout his life. When he personally expelled the disciples who had fallen into the devil's way from his school, he thought that all ties and righteousness would be cut off from now on.
Unexpectedly, the expelled disciple refused to accept his fate and pressed forward step by step with his demon body, pestering him endlessly. From the flashes of swords and swords in the siege of the Immortal Sect to the treacherous disputes within the Demon Clan, the two are forced to stand side by side again and again. The impenetrable "barrier of good and evil" in his eyes gradually cracks - it turns out that the demons also have guardians, and there are even more sinister plans hidden in the path of immortality.
When his inherent understanding collapsed, he finally admitted that demons were not all evil. But when faced with his disciple's loss of awe and directness of mind, this old-fashioned immortal who didn't even understand Feng Yue was completely panicked.
"Master and disciple have different paths, immortals and demons are different, not to mention..."
"What's more?" The apprentice smiled, his eyes stained with demonic patterns, and pressed forward step by step, "Master taught me to distinguish between good and evil, but he didn't teach me what my heart desires. Why should I be divided into men and women?"
