Although Ye Shuang told Xiao San to leave the man where he was, Xiao San was not just blindly following her commands.
Though the mountain was huge, what if the man's partner happened to see him tied up? It would be a pain by then, and they could forget about baiting the big fish.
Moreover, it was a jungle after all. Even though there were fewer ferocious beasts in modern society, what if he encountered a big one? A stray dog might eat him alive if he was tied up while out of it.
Thus, Xiao San had gotten someone to move the man to a dense bush that was secluded and told the underling to watch him. Even if he really needed manpower at the mine, the twenty or so men over there should be enough.
He finally realized that Ye Shuang had only ever been responsible for killing, not burying the bodies.
As usual, the mine was quiet and empty. It looked like it had been years since someone had entered it. Indeed… nobody was there.
