In ancient dynasties, a delicate balance was maintained between Jianghu forces and the imperial court. Twenty years ago, the "Blood Moon Incident" triggered a catastrophe in the martial arts world, and various sects hid new crises in the process of reconstruction. The story begins in Jiuyi Mountain in Qingzhou, which is both a holy land of martial arts and the location of the dragon veins of the previous dynasties. The misty canyons in the mountains contain ancient ruins, and the cold pools at the bottom of the cliffs connect to underground rivers. On the surface, it is about encircling and suppressing the remnants of the Demonic Cult, but in fact it involves the fight for the secret treasure of the previous dynasty. The leaders of each faction seem to share the same hatred, but they have their own plans in private, and undercurrents are surging on the eve of the Heroes Conference.
