The middle-aged man showed no reaction to Gao Ming's choice, as if everything was expected and had already occurred many times over.
Opening his backpack, Gao Ming searched for a while, then suddenly looked up with confusion: "Why is it gone?"
"What are you looking for?" The middle-aged man also sat down beside the couch.
"Looking for..." Gao Ming touched his head: "It's something very important, but I can't remember what it is, I should have brought it with me!"
His expression became somewhat agitated, and Gao Ming, refusing to be disbelieving, lifted his backpack and turned it over a few times. Various stationery and books fell to the floor, but even with the backpack emptied, he still couldn't find that item.
"This is bad, it must have been forgotten in that tunnel!" A hint of panic shone in Gao Ming's eyes: "It must still be there in that tunnel!"
