Dragon X: Gap of the Abyss

The mysterious antique sent by an unknown person is engraved with dragon inscriptions and tells the myth of creation. This time, they are about to meet the King of Ocean and Water! The sea and the sky are hanging upside down, and the dragon slayer will eventually become an evil dragon! Raise your sword, though death is imminent! Mortals, confused sons of men, dragon slayers, raise your muzzles to me. When He falls into the depths of the sea, the tombstone will look dim, even though the sun will eventually rise... Because this is the beginning of the end.
