The Gray Sea wasn't the best place for Adam to fight because it was mostly water.
Sure, there were plenty of islands in the Gray Sea where Adam could feel comfortable, but the monsters there had shown that they could drag their opponents underwater to gain the upper hand.
For this reason, Adam was wary of the Grand Abyss.
He understood that if this place was located beneath the Gray Sea, then everything here would be underwater, and that wasn't even the biggest problem. At such a depth, he would be constantly subjected to intense pressure, and a powerful aura would weigh down on him as well.
