If this wasn't an imitation by someone, Wang Tao felt there was a high probability it was a hallucination. He had previously encountered a Black Mist Monster in Shuize County that could use illusions to influence people's thoughts.
Jiang Shixue might be immune to the illusions due to her unique constitution.
So, if all three of them heard the sound but Jiang Shixue didn't, then they were definitely affected by an illusion!
But to Wang Tao's surprise, Jiang Shixue could hear it too!
Now there could only be two possibilities: one was that the illusion was so strong that even Jiang Shixue couldn't avoid it, or this wasn't an illusion at all but something Wang Tao had never seen before…
"Retreat!"
Wang Tao had always held a sense of reverence for the unknown.
Having realized that he couldn't determine the situation at hand, he immediately instructed Xu Xiaojun to evacuate the area.
But what nobody expected was that the environment outside had changed without them noticing!
