If this situation continues, there are two possible outcomes: either the monster's body will feed all the fish gathered nearby until they are full and stop eating, and if there is still enough blood, the monster could eventually revive.
Or the speed of the blood's repair is not fast enough to keep up with the speed of the surrounding fish gnawing, and ultimately the body will be completely devoured by the fish in the water.
Zachary feels the second scenario is more likely, as based on his past experience with fishkeeping, most fish basically do not have a sense of fullness like mammals do, and if fed enough food, those fish would eat until they burst without stopping.
Moreover, because they are drawn by the blood, more and more fish continue to gather here.
