Seeing the mighty Dragon King kneeling before him, so pitiful, Li Ping'an instead kindly said:
"I acknowledge your deep paternal love and the love you have for your children, and the suffering you have endured for five hundred years here. Very well, I shall agree to your request..."
"Thank you, Immortal!"
"Don't be too happy just yet. I don't know when I will encounter your nine sons, and even if I do, I have no proof of this encounter. How would they believe me?"
"Immortal, don't worry, Xiao Wang will give you something that will make my nine Dragon Sons definitely believe you."
"What is it?"
Dragon King of the Jing River, Ao Lie, immediately opened his dragon robe, tore off a piece of dragon scale from his chest, and handed it to Li Ping'an:
"This is the hardest dragon scale from our Dragon Clan, capable of blocking ordinary water and thunder spells. My children will surely recognize it. Today, I give it to you, Immortal, only asking that you must keep your promise!"
