The Northern Dark Sea was originally the breeding ground of the Kunpeng tribe.
With the protection of the Kunpeng Ancestor, it became a territory where no one dared to interfere.
The Immortal Realm's four major seas, appointed by the Heavenly Court's Dragon Kings, dared not set foot here.
In this ocean, some mimicked the Netherworld, devouring Yin Spirits from across the Immortal Realm's seas, creating a small Underworld here.
These Yin Spirits could not reincarnate or enter the cycle of rebirth and could only be driven and refined here.
Due to the sheer number of Yin Spirits, the ocean's color appeared somewhat dark blue.
Hence, it looked like an ink sea, earning the name Nether Sea.
Song Yuchan and Yan Qing stared at this sea, their eyes wide open, as they had never seen such a place filled with Yin Malevolence before.
In the air, although protected by the barriers of the Chaos Beast.
They couldn't help but feel cold, as the wind brushed against them, feeling icy.
