Misty Fey Sea

It was a summer morning. The vast sea surface was calm while a layer of mist shrouded above it. Occasionally, there would be a few school of large fish traversing across the surface of the sea at extremely fast speeds, causing wave breaks in the water surface.

The Untraversable Sea was the sea surrounding the Tian Yuan world, but in fact, when warriors mentioned the Untraversable Sea, they were mostly referring to the vast sea region to the north and west of the Tian Yuan continent.

The deeper one went into that region of sea, the thinner the Heaven Earth Yuan Qi would become. Even marine life became extremely rare the further one went. Even warriors at the Empyreal King realm would not receive the supplement of Heaven Earth Yuan Qi when they flew through this region, so naturally they did not dare to venture too deep. This was the true meaning of "Untraversable".
