"I'm really envious, extraordinary creatures don't need to consume magic potions like us Spiritual Ability Users to resist the corruption of the Void Realm. Just normal growth can enhance their strength," another captain laughed, "If we humans had such ability, the Forbidden Zones would have been eliminated long ago."
"No, in the eyes of extraordinary creatures, even Ancient Dragons, humans are the peculiar creatures," the elderly Sword Madman laughed. "Ancient Dragons need thousands of years to mature and advance to the Overlord level. Whereas we humans, can advance to the Overlord level within a hundred years, even within just a few decades."
Everyone laughed and nodded, that was indeed true, humans advance much faster than extraordinary creatures.
Of course, if extraordinary creatures want to accelerate their growth, they can also devour other powerful beings. But that would be very dangerous.
