As Wei Yiling explained things to him,
Li Ping learned that the Eastern Sea was actually a collective name.
Cultivators divided these waters into two regions: the coastal waters and the deep sea.
The coastal waters belonged entirely to humans. Human cultivators occupied vast numbers of islands, and neither intelligent Otherfolk nor Demon Beasts that had assumed human form ventured into this region.
Thus, the strongest Demon Beasts in the coastal waters were only at the third-tier late stage. This was also where she mainly hunted them.
As for the deep sea, it contained not only tribes of Otherfolk such as the Sea Folk and Merfolk, but also the Demon Race Royal Court, headed by the Flood Dragon Clan. There were considerable numbers of fourth-tier Otherfolk and transformed members of the demon race there, making their strength no less formidable than that of the Immortal Alliance.
For that reason, human cultivators rarely set foot in those waters.
Just as Core Formation Cultivators like Wei Yiling only dared hunt Demon Beasts in the coastal waters, the Eastern Sea Four Fiends, who made their living plundering other Core Formation Cultivators, also operated near the coast.
In fact, they did not merely rob lone Core Formation Cultivators.
The third-tier Spirit Islands in the coastal waters that cultivators managed were also targets for their raids...
Li Ping kept nodding, then asked curiously, "Are there any fourth-tier spirit veins in the Eastern Sea's coastal waters?"

Li Ping had long known this.
Otherfolk and Demon Beasts differed
