The Gift of the Gap

After the exploration by generations of powerful cultivators, the veil over the three celestial mountains was beginning to fade, and they laid in wait for a fortunate passer-by to control them.

Amongst the three, Penglai Celestial Mountain had a sea on its own. The waters were murky and dark, giving it the name 'Dark Sea'. There was no wind but yet there were powerful tides that surged up to over hundred feet high and moved with the mountain, protecting it wherever it went.

This Dark Sea was different from the Netherworld Sea and its real name was Vast Black Sea.

The intensity of its blackness was comparable to the darkness of the sky above. Its vastness was comparable to that of the void battleground where an ocean of space exists. Hence, it was given the name Vast Black Sea.

For the common folk who wanted to access Penglai Celestial Mountain, the Dark Sea was an effective deterrent.
