"The sound isn't coming from some place behind the door..."
Upon stepping into this corridor, Ling Mo had already noticed the oddity of those noises.
But, with nothing unusual at both ends of the corridor, including within the walls, he naturally turned his attention to the spots adjacent to the corridor. However, standing here now, he faintly felt a weak vibration...
"Is it an illusion?"
Ling Mo frowned, took two steps forward, and then retreated.
Two seconds later, he simply squatted down on the ground, placing his palm on the surface, slowly moving it around.
"What's this guy up to now?" Tang Hao and Little White followed behind, maintaining a distance of about five meters from Ling Mo. He glared somberly at Ling Mo, but his gaze involuntarily followed Ling Mo's actions.
"He himself said that they only have two minutes left, so why is he wasting time here?" Tang Hao thought anxiously.
