Primeval Devil Heaven was one of the Thirty-Three Heavens and the Devil Race's main stronghold. Ever since the Gods and Devils Clan had withdrawn from the world, it had become incomparably chaotic.
This land was vast and boundless. Countless devil clans, devil sects, and devil kingdoms coexisted, waging endless wars against one another.
If one spoke of the strongest forces in Primeval Devil Heaven, they were naturally the ten great devil clans, ten great devil sects, and ten great devil kingdoms.
The Dark Devil Clan stood at the head of the ten great devil clans. Its foundations ran deep; rumor had it that not only did an unparalleled Immortal King preside over the clan, but an ancestor at the half-step Immortal Emperor level was also hidden behind the scenes. Yet no one had ever seen him with their own eyes.
The Nirvana Devil Sect stood at the head of the ten great devil sects. Renowned throughout the world for the Great Daos of slaughter and nirvana, its sect master, Tianshu Star Lord, was a high-level Immortal King with unfathomable strength. Several Immortal King-level elders served beneath him as well, making the sect's power enormous beyond compare.
The Heaven-Dominating Devil Kingdom stood at the head of the ten great devil kingdoms. It occupied the richest eastern lands of Primeval Devil Heaven, and its emperor, the Tyrant Dragon Devil Emperor, was likewise a high-level Immortal King. There were even rumors that an old fossil at the half-step Immortal Emperor level was hidden within the Heaven-Dominating Devil Kingdom's imperial family.
These three forces were the three strongest giants of Primeval Devil Heaven on the surface. Each occupied its own territory, checking and balancing one another as they maintained a subtle equilibrium.
But these were merely the forces in the open.
