Yang Xi looked out the window with a helpless expression, knowing that besides waiting, there was nothing else they could do. The entire base had entered a state of high alert, with everyone's nerves stretched tight, ready to respond to any potential attack at a moment's notice. Yet, despite deploying various advanced monitoring systems, the enemy remained as untraceable as ghosts.
"Yang Xi, can they really turn invisible? Why can't our surveillance, infrared alarms, and even thermal imaging equipment detect them?" Su Qiuyu asked, her brow furrowed in doubt. Her heart was filled with puzzlement, and she felt utterly confounded by such a mysterious enemy.
Yang Xi pondered for a moment before replying, "Perhaps they're using some kind of high-tech gear that can shield or interfere with these devices' signals. Or maybe they possess unique abilities that allow them to bypass these monitoring systems. Either way, this is a headache-inducing problem."
