East Sea.
It was rumored that there existed an immortal mountain in the East Sea, which Gu Xiao had once visited, but the island was inhabited only by Wa people.
Perhaps Penglai was at the world's edge, the Penglai Immortal Mountain amidst the storms at the very brink.
Years ago, when Gu Xiao encountered danger, he returned to the Divine Land, but with his increased cultivation over the years, Gu Xiao wanted to explore it once more.
"Since there aren't many years left for me to live, when else should I take the risk, if not now?"
Gu Xiao thought.
Having said that, he boarded a ship and headed towards the vast sea.
Both the ancients and he himself understood that this world was a dome over a square earth.
What was even more intriguing was what lay at the edge of this dome and square earth?
Was it an endless void, or perhaps an encased by a formation?
Divine Land was the center of the world, and beyond it, the land grew barren, followed by islands, and then the boundless sea.
