Staring at the strange objects on the necks of these mutant corpses for a while, Tang Ye seemed to recall something. He patted his pocket and realized he had not brought his smartphone. Then he asked the soldiers around him, "Do you have your phone with you?"
"Yes, Marshal!"
The soldier jolted, hastily pulled out his smartphone from his pocket, and respectfully handed it to Tang Ye.
He didn't hesitate, taking the smartphone from the soldier directly, opening an app developed after the apocalypse. With the interface loaded, Tang Ye expertly tapped the magnifying glass icon in the top right corner and typed, "Proud to report, this device has been developed and we need no longer fear rebellion from those below us. Superiors, do you love it?" followed by a few dozen characters.
Tang Ye hit search and a video popped up soon after. He opened the video, which primarily introduced a slavery device developed ten months ago in a certain Sanctuary City.
