This black dragon was simply too huge, far beyond the size of average dragons. Furthermore, his strength also exceeded Roy's understanding of dragons.
Roy was actually a little stunned. He remembered that this black dragon, known as the Destroyer, seemed to be transformed from Abaddon, a leader of the angels, but Roy did not know what actually happened in the middle.
While Roy was thinking about if this was the Destroyer's first appearance, he suddenly heard Gasric's excited voice. "Those angels were killed! That black dragon seems to be on our side!"
What Gasric said was the group of angels that Roy had encountered earlier, the ones who had gone out to sea to search for traces of human ships. After hearing this, Roy looked in the direction the angels had gone. As expected, he could no longer see the angels in that direction, only some bloodstained feathers floating on the sea along with the waves. The pure white color was very conspicuous in the blue seawater.
