When Malina finished taking her parents on a short tour through the capital, the fight between Arad and Arian had ended. The little guy was already tired and beaten to a pulp, carried by Arad like a bag.
Arad showed up behind them, and Malina's parents rushed to check on their little boy, finding him too exhausted to move but without a single wound.
Arian's mana and stamina had both dropped to zero. Arad had let the little kid go as crazy as he wanted and use all of his power to test his limits in battle, and that seemed to have a decent effect.
Malina's father couldn't believe his nose because he could smell it now. In just a few weeks, his son might go into hibernation. He had been waiting for years, even paid famous and skilled trainers and healers to check him, but one fight against Arad was enough to do the trick.
Dragons don't run, get tired, then stop to rest; they run until they pass out. Dragons won't give up because of pain; they'll fight until death takes them.
