She had been standing here for over half an hour and hadn't seen a single person enter, where did he go in from?
Wushuang closed her eyes and visualized the construction blueprint of the castle in her mind, her gaze drifting toward the direction of the sewer, her brows furrowed, then suddenly she smiled, probably it was through the sewer that he had entered.
But how did these wolf dogs detect someone's presence?
If no suspicious scent had lingered on the ground, it wouldn't have been possible for the wolf dogs to smell anything, not to mention raising an alarm. After all, not even the surveillance room knew what had happened. Wushuang pondered without any conclusions, switching to a pair of dual-purpose binoculars.
Besides being military binoculars, these were also a special device that could identify any threatening weapons within the field of view. No matter who this person was or why they were detected, it was a good thing for Wushuang.
