Capítulo 226: Lacking Only One Element 

Hearing this answer, Chen Chen felt relieved. 

Fortunately, it was still within this realm. However, he didn't know how the treasure of that Void Refinement realm expert lost the treasure there. 

If he went more than 150,000 kilometers east from the Eastern Border, he would reach the Boundless Sea. 

As the name implied, the Boundless Sea was endless, and the countless areas of the sea were larger than the territories of the human race and demons. 

There were few human cultivators in the land near the sea and some scattered islands. However, the further depths of the sea were the complete ocean. 

It was the territory of the underwater demons. 

Rumor had it that some extremely old demons had lived for tens of thousands of years and were massive in size. They would remain dormant and stationary for thousands of years. Once they moved, there would be tsunamis and destructive disasters that would make the earth crumble.
