Ren Long and Chi Yu were immediately attracted by the words 'Nine Ancestral Dragons'. Their ears perked up and they started listening carefully.
They have known Fu Ming for a very long time and understand him well. They know that Fu Ming is a very reserved person and would not speak words that have no meaning. And since he is telling them about Nine Ancestral Dragons, it means he has enough proof to back up his words.
Moreover, they found the topic interesting.
Fu Ming continued: "After the birth of first-generation dragons, a great calamity befall the Heavens and nine Ancestral Dragons disappeared. But those first-generation dragons couldn't forget about the might of nine Ancestral Dragons. Thus, they thought of creating a dragon that is equally powerful to any one of those nine Ancestral Dragons."
