Sima Grotto-Heaven? Endless Sea? Emperor Yuan Feng silently noted down what Zheng Yongtai said.
If Zhou Shu was here, he would definitely understand what Zheng Yongtai meant by Sima Grotto-Heaven.
But Emperor Yuan Feng and the others didn't know about the existence of grotto-heavens. They thought that the place Zheng Yongtai was talking about was an island in the Endless Sea.
This surprised everyone.
The Endless Sea was an endless sea outside the Ten Nations Continent. No one in the Ten Nations knew how big it was.
The Endless Sea was full of dangers, and even first-rank martial artists were unable to return if they ventured deep into it. Therefore, very few people from the Ten Nations had ever gone deep into it.
The Endless Sea was most famous for the Heavenly Rock beside it.
