"Right, when I participated in the grand competition held jointly between our sect and the Yuan Beast Sect, I noticed that the evil beasts controlled by their cultivators, when looking at strangers, had a similar look in their eyes as Elder Brother Wei did before he went berserk."
The words of Tian Chengxu made Han Yi mostly certain about his guess.
Zhuo Qun's disappearance and Wei Tushen's madness couldn't be detached from the Yuan Beast Sect in any way.
A moment later.
Han Yi left the Profound Immortal Pavilion grounds in a flash. Before leaving, he instructed Tian Chengxu not to worry since Supreme Elder Zhuge Wu You would be arriving later, and to carry on with his own tasks in the meantime.
With the Light Body Technique of the Return to the Truth and the Disguise Technique, unless he was face-to-face with Gold Core cultivators or there was a Nascent Soul Sovereign nearby, it was nearly impossible for anyone to discover traces of Han Yi.
