Bab 662: Chapter 664 Didn't Plan to Make You Believe Part 1

"You actually want to challenge me to a duel, heh, you're just too naive!" Xuanyuan Aotian scoffed, then his hand emerged from the pocket of his clothes, holding something new.

Cheng Qincheng, standing nearby, when she saw the thing in Xuanyuan Aotian's hand, her face showed a hint of envy and respect.

It was a small booklet, just like a regular identification book one might see.

About the size of an ID card, with a red cover, upon opening it, there was only one piece of paper inside, filled with writing and covered with seals.

Chen Hao was already very close to Xuanyuan Aotian, and when the latter showed him the credentials, he could clearly make out what was written on it.

"What is that?" Zhao Ning muttered to himself.

The people around all looked on with curiosity.

They all wanted to know what amazing thing this mysterious Master Xuanyuan would bring out.

Was it a manual of Divine Skills? Or a warrior's License to Kill?

But soon, they all showed a look of shock.
