"Old Mo...?" Lin Yi stared with wide eyes, shocked at the Old Mo before him, "Just now...?"
Old Mo calmly nodded, "Did you just experience an auditory hallucination?"
Lin Yi was greatly shocked, "You knew?"
Old Mo shrugged, "It's nothing new to me. It's all 'old routine'; you get used to it after seeing it enough times..."
"Any creature, when traversing the Safe Boundary, will perceive some special fluctuations due to the differences between Layers. It's normal for you to hear them... But that said, could you tell what those sounds were calling out for?"
"I...I can't make it out at the moment." Lin Yi shook his head; the voices were both unfamiliar and familiar, yet his reaction lagged, "What's the matter? Is there a specific reason?"
Old Mo patted the Pig-killing knife tucked behind his waist, "That's the reason, and it's okay if you can't make it out. Let's go, this journey will be interesting."
