The curse has created a situation where if he is to continue living, he must guard the Ocean of Blood and prevent it from being taken by anyone.
The meaning and duty of the curse were clear to him as soon as he tried to probe it. This was to ensure that he would know his duty.
After learning of his situation, he remembered what the giant had said before it died. He also remembered how the god of justice had guarded the Ocean of Blood for many years and how the church of justice hunted killers for so many years.
His face fell as he said, "So not only do I not win, I also have to guard the Ocean of Blood. This must be why he said that even gods would not mess with the Ocean of Blood right now."
It was clear to him that he was going to die if he tried to take the Ocean of Blood. But that only made him pause for a while.
