Was it the wolves? No.
The soldier's silver snakes were fitted with extra camera equipment that could send back an image feed via the nanomachines' neural connection. So even though that shadow was extremely fast and the image was blurry, the soldier was very sure it wasn't a wolf.
Captain Zhou looked at him and wondered, "If it's not a wolf, what is it?"
"It looked more like a… shadow," the platoon member said. But at this moment, he exclaimed again, "Oh no, my silver snake is getting out of my range!"
He then chased after it and tried to keep within the control range of the nanorobotic, silver snake. However, his speed was way lower than his opponent's. Before he could even cover two steps, his neural connection to that silver snake was completely cut off!
