Su Ping was headed for an island named Black Tortoise Island.
It was an expanse of nearly a hundred square kilometers, making it one of the larger islands among the Overseas Islands.
The island was home to a fishing village with about two hundred people.
According to the records Su Ping could find, Black Tortoise Island had once been the headquarters of the Xuanwu Sect from Ancient Times.
At its peak, the Xuanwu Sect was rumored to have had Immortals who received tributes from thousands of sects, making it a top-tier sect.
However, as time passed and the sect's strength declined from one generation to another, it was eventually destroyed for resisting the tyranny of Immortal Chiyuan.
It was said that in that battle, the spirit vein of Black Tortoise Island was extracted, and the remnants of the Xuanwu Sect were obliterated with a single sword.
From then on, the Immortal Cultivation World no longer had the legacy of the Xuanwu Sect.
