Venerable Black Turtle had never expected that Zhou Bao would have refined the Elixir of Nine-headed Fierce Beast.
Although it was a Powerful Divines' mountain-guarding holy beast at antiquity times, it was not a Primordial Fierce Beast. It just had some blood relationship with Primordial Fierce Beast. The Nine-headed Fierce Beast was one of the Six Royals. The Primordial Fierce Beast at antiquity times greatly surpassed him in terms of the strength and level. Therefore, when Zhou Bao was showing the Infinite Poison Banner, he sensitively felt the Primordial Fierce Beast's ferocious spirit. He was so scared to have suddenly jumped, like a cat's tail was stepped on.
"Yes, It was the Elixir of Nine-headed Fierce Beast. But it's not pure. So, it's easily refined." Zhou Bao was startled by Venerable Black Turtle's reaction and explained to him in detail.
