"Director, come look at this!"
Hearing a warrior's shout from inside, Su Mo pulled himself out of his thoughts and headed toward the source of the voice.
He didn't have to go far. Halfway down the third access tunnel, Su Mo immediately spotted Deputy Captain Feng Long, who was leading the fourth squad. Right now, the man wasn't inspecting the supplies or facilities inside the cave. Instead, he was sprawled on the ground, shining a flashlight and staring intently at a bloodstained patch of dirt.
"Is there something wrong with the ground?"
Su Mo stepped closer and studied it for a moment. Although he felt a sense of familiarity, he couldn't immediately recall where that feeling came from.
"Director, it's not the ground—it's this footprint!"
Moving briskly, Feng Long sat up and pulled off the Customized climbing boot from his foot.
