The person behind him wearing a small pig mask was Zhang Yu. The two of them had come to this bazaar specifically to participate in the exchange meet, only to happen upon the battle between Qin Xuan and Lan Feiyu.
Mu Chen had spotted Qin Xuan the moment he entered the underground hall. He had even observed him in secret for a while, never imagining that Qin Xuan’s senses would be sharp enough to detect him. For a moment, Mu Chen felt uneasy. He knew he couldn't win—the sight of Lan Feiyu’s miserable state was still fresh in his mind—and Qin Xuan seemed to have a foul temper; he might just decide to beat him up on the spot.
However, Mu Chen had underestimated Qin Xuan. Qin Xuan had noticed Mu Chen and Zhang Yu the moment he walked through the door. A person can hide their face, alter their height or build, or even change their appearance and gender, but they cannot change their aura. This was especially true for a bladesman like Mu Chen; the sharp, piercing aura emanating from him could not be fully masked, at least not until his bladework reached a truly transcendent level. That was how Qin Xuan identified him. As for Zhang Yu, Qin Xuan had beaten him up personally, so he naturally remembered his aura.
