The so-called Golden Giant refers to a huge humanoid creature whose body is covered with golden scales.
After circling in the sky, the black dragon had pinpointed the appearance of the castaway. From above, it could clearly see a faint trail of blood spreading in the direction from which the giant had drifted.
Surrounding this trail of blood, various sea creatures, large and small, floated belly-up on the water surface, creating a rather shocking sight. This also explained why a creature that seemed defenseless could remain unharmed while drifting on the sea.
This creature, shimmering with golden light and appearing fierce and towering, was entirely toxic. However, the fact that it hadn't been eaten only indicated that the creatures attempting to bite the giant weren't particularly adept.
Truly powerful creatures could drink deadly poison as if it were water and might even relish tasting it, much like himself.
