"If they can do that much… how can they ever be defeated?" Rain thought.
If the dragons also absorbed the essence and information on the bodies left by everyong they killed, possibily by devouring them, they probably had infinite potential… their power doesn't come only from their bodies being able to amass insane ammounts of mana, but because they also had that kind of trait…
The most recent dragons didn't have that kind of power, so it wasn't an ability that could be passed down… or perhaps they didn't have any connection with the old dragons. Rain wondered if those memories would help him confirming that or not.
A long time passed once more without nothing happened… then all of a sudden, Zeus noticed some changes taking place in the world. The whole planet trembled for several days straight and he thougth that the planet was trying to revive itself, but nothing of the sort happened… instead all the mana hidden within the depths of planet began to emerge.
