"Outer Sea of Tianlan" was Demon Race territory, the domain of the Black Bone Demon King.
Having become a Sixth-Rank Demon King less than a thousand years ago, the Black Bone Demon King still had much to learn.
Thus, he normally remained in his Water Mansion beneath the sea, cultivating the Demon Race cultivation methods and secret divine abilities he had obtained from the flood dragon clan, while also studying artifact refinement, alchemy, talisman crafting, and related knowledge.
But that did not mean he ignored all outside affairs.
The meaning of his presence in the "Outer Sea of Tianlan" was to ensure that this place remained Demon Race territory. Human cultivators could come here to seek adventure, but they could not claim land, establish residences, or establish sects. That was the bottom line set by the flood dragon clan.
Since the "Outer Sea of Tianlan" had been occupied by the Demon Race for several thousand years, the cultivators of the Overseas Cultivation World had tacitly accepted the Demon Race's rules after their initial attempts to reclaim the area failed. No one had tried to establish a sect or build a stronghold here again.
Therefore, the Black Bone Demon King had lived rather comfortably these past years. Aside from occasionally leaving to patrol his territory, he had rarely been troubled by matters outside.
But several days ago, while cultivating in his deep-sea Water Mansion, he suddenly received a report from a Tier 5 Demonic Beast that a Human Race Golden Core Stage Cultivator was forming a Nascent Soul in the "Outer Sea of Tianlan."
How could he tolerate that?!
After becoming a Demon King, the Black Bone Demon King's wisdom and knowledge had greatly increased. Naturally, he understood where the threat posed by Human Race cultivators to the Demon Race lay.
