Yuan Bomian furrowed his brows, wanting to say something, but then stopped, saying, "The clues we currently have are pretty much exhausted when it gets to Redface. Catching Redface was already a bit of a stroke of luck..."
Yuan Bomian explained as best he could: "Redface distributes goods by car. Moreover, before distributing, he should always privately confirm the situation with these small vendors. Then he'd drive to the side of a vendor, use a disposable phone to call the vendor below, connect the call, agree on a place, say how long it takes to get there, and he must arrive within that time."
Liu Jinghui immediately realized the difficulty involved, saying, "Then as long as he monitors the vendor in advance to ensure there's no problem and only then makes the call, arranging for a place without cameras, he's basically not going to be exposed. So, how did you catch the person?"
