The Dragon Clan fell into the remnant clan of the Eight Desolations. The young master Long Jin bears an incomplete main dragon vein, making it difficult to awaken supreme power. He walks out of the remnant valley, awakens the desolate ancient supreme dragon soul in the secret realm, but discovers that revitalization is not solely relying on awakening. Long Jin unites with Qing Lan of the Spirit Phoenix Clan, collects evidence of the severed vein conspiracy, takes back the dragon clan's supreme treasure, repairs the nine dragon vein nodes, and fights against the Taotie ancestor's leyline plunder. In the end, he discards the hegemony of the old era and establishes a new order of the Eight Desolations jointly guarded by all clans.
