"How did such a monster appear in the Human World?" Gladly this guy holds no hostility towards Giant Dragons and doesn't rely on hunting them for a living. If he were a hero or a Dragon Slayer, the pureblood dragons of Human World surely would all be pillaged by this guy.
Can humans be this strong?
Nightmare Evil Dragon Koln recalled the names of some powerful humans from over eight thousand years ago.
Humans really can be that strong; their methods of cultivation are endlessly emerging.
Martial arts, summoners, alchemists, card makers...
Some powerful humans can directly become deities.
Given the vast number of humans, it's normal for a few to have the strength to slay dragons.
Luckily, humans don't live as long as dragons, or else no other exotic races would stand a chance in this world.
Attack power isn't strong.
Defensive power, strong.
Nonsense.
This filthy thing's attack power and defensive power are probably on the same level.
