Facing the surging blood-colored waves, Seven Kills showed no trace of fear. His hands moved like spinning car wheels, forming seals, as he sprayed out a mouthful of pure mana, merging it into the Five-Color Flag Box.
The five small colored flags inside the box immediately shot out, scattering abruptly in different directions, landing in five spots around the Blood Sea. With a soft "puff," they pierced into the void.
Golden, green, blue, red, and yellow beams of light radiated from the commanding flags, accompanied by countless flashing five-colored spiritual symbols that rapidly connected with one another.
Within moments, a massive five-colored light formation coalesced into shape, enveloping the entirety of the Blood Sea.
The blood-colored waves slammed fiercely against the light formation, causing it to shudder violently. Cracks emerged across the formation, and large sprays of blood surged forth, yet the majority of the Blood Sea remained confined within its bounds.
