The Supreme Treasure?

"Within 100 years," the Heaven Ancestor said, "the key is to find out who has the nether-fire blood crystal. As long as we can confirm it, it'll be easy. We can think of other ways to exchange for it. If the other party doesn't agree...then we'll use force. No matter what, there will be a result within 100 years."

Jian Wushuang nodded slightly.

He was willing to wait for a hundred years.

"In addition to the treasures on this list, I also need an offensive magic weapon, one above the Pinnacle Universe Supreme Treasure," Jian Wushuang said.

"A magic weapon?" Daoist Xuan Shen and the other two looked at each other in dismay. They were not surprised by this request.

They all knew that the magic weapon Jian Wushuang used before was only at the advanced universe supreme treasure level. Even if he killed Nine Sword Demon Master and obtained the Supreme Treasure in his hands, it would only be a top-tier universe supreme treasure magic weapon.
