Adam had only one task left in the Gray Sea - to find and kill Breydar. Once he did that, he would be able to return to the Citadel. This would mark the beginning of his journey to destroy the Grand Barrier.
But before he could kill Breydar, he had to find him, and to do that, he had to reach at least Island A150, which was quite far away.
The Gray Sea was structured such that the farther an island was from the shore, the more dangerous it was.
Thus, on Island A50, the monsters were much weaker than on Island A100, let alone Island A200.
However, Adam now possessed enough strength to defeat a Viscount. He had enough power to move about freely here.
In fact, in the Gray Sea there were islands so far away that it would be dangerous even for regular Second-Rank Phantoms, such as the heads of the Twelve Branches, well, most of them, to venture there.
These were the islands numbered over 1,000.
