The four wristbands had all failed at the same time. There was no way that was a coincidence.
"In other words, someone tampered with them—"
Jack did not know whether the other party had directly blocked the wristbands' signals or simply destroyed every wristband outright.
But either result meant one thing: that shadow was definitely not merely a drifter or raider who happened to pass by.
After all, if it were just one person, there would have been no need to go to such lengths—and no ability to block communications across an entire area.
In other words—
"This is an organized operation!" Jack exhaled.
Only enemies who were organized and prepared would set something like this up in advance.
As he thought of that, Jack's gaze gradually turned cold.
That meant the entire Graduation Trial had very likely already been targeted!
The thought made Jack's heart sink.
He slapped his face hard, forcing himself to calm down. "No—the disappearance of the signal is itself information."
If the signals had merely been blocked, the military should have quickly noticed the anomaly. After all, an entire region's distress wristbands going offline at once could not possibly go unnoticed.
But the problem was—what if the other side had done more than just block them?
Judging from how swiftly and cleanly that shadow had left in the end, the other party was likely hunting students like them with a specific purpose.
Jack did not think he and Xi Ya were any different from the others. An operation on such a massive scale would inevitably make a great deal of noise. If the enemy had some objective, they would definitely delay things as long as possible.
And judging from the current situation, to launch such a wide-ranging operation while also delaying things for as long
