"What method could drive animals mad?" Qin Sisi raised a crucial question.
Large animals live secluded in remote mountains and grasslands, rarely encountering humans face to face; while ordinary small animals do coexist with humans in the same area, they generally can live in peace, and such horrifying events have never happened before.
After pondering for a moment, Ye You replied, "There are two possibilities: one is drugs, the other is illusion techniques."
"Illusion techniques?" Qin Sisi's heart skipped a beat, and she looked at Ye You with complex emotions, Ye You's expression was also heavy.
If it truly is illusion techniques, then it indicates that the Phantom Spirit family has already rebelled, or rather, someone in the Phantom Spirit family has betrayed.
Mu Zhen thought for a moment and said, "There are many animal bodies here, we can check them to see if they're poisoned."
"Alright." Ye You nodded in agreement.
