The Devil Dragon Clan had an incredibly slow reproducing speed. They would be able to give birth only once every hundred years, and there would only be a single descendant every. Maybe it was because of their status as demons, but these Black Dragons’ method for giving birth was entirely different from the other dragons’. They weren’t born as eggs, but as a fetus, and this was the first reason why the Devil Dragons would be so powerful upon birth. Every time they gave birth, a single Devil Dragon would be born. Twins would only appear once every 1,000 years.
