Yan Clan Stronghold is in upheaval. Once a century-old clan devoted to eradicating evil and upholding the righteous path, how can they now turn to the demonic way? However, every voice of dissent is suppressed by the clan leader, and in the end, Yan Clan Stronghold's defection to the Ghastly Spirit Sect became a foregone conclusion. They send wedding invitations of Yan Ru Yan and Wang Chan to the Seven Sects. Nangong Wan senses that something is amiss.
