"But the 'Black Cat' self-detonated just as we located it." Cold sweat beaded all over the chief secretary's forehead, but he still rapidly said, "This is the image that was relayed back before the 'Black Cat' self-detonated."
"Self-detonated…" The old man's body swayed and he reached out to grab the table. He barely controlled his emotions as he watched the chief secretary turn on the virtual screen to show the image.
