Song Heping's hand stopped when it touched the inner lining at the back of the backpack.
That area is usually a combination of a support board and sponge, meant to enhance support and comfort during use.
But at this moment, his fingers encountered something hard hidden within the sponge.
Song Heping carefully inspected it and felt it again, confirming it wasn't a part of the backpack's support board. Upon further inspection, he discovered a data cable at the bottom of the backpack, running along the edge, seemingly leading somewhere.
He checked again but couldn't find where it led.
Song Heping simply pulled out a butterfly knife and sliced open the back panel position.
The sharp blade easily cut through the lining.
A black box appeared before Song Heping.
"Damn, what is this?"
Jiang Feng came over at that time, also looking perplexed at the small object.
