Thinking of this, Ah Dai couldn't help but feel a sense of defeat. Why would the evil aura and malevolent aura gather in his brain? If they were elsewhere, he might dare to risk an attempt, but the brain's structure was so complex and fragile—it was truly challenging. He couldn't think of a proper solution for half a day and decided to first retreat from the meridians before figuring it out. His entire body was currently enveloped by the evil aura, but he didn't dare to resist it too much and could only channel his golden energy internally, retreating swiftly outward. Although Ah Dai didn't dare to confront the evil aura within the meridians, the evil aura had no intention of letting him go. As his body retreated, the evil aura chased him rapidly, continuing to envelop his body.
