Jiang Baimian didn't answer Shang Jianyao's question. Instead, she looked at Long Yuehong and gave him the opportunity to analyze the situation.
Long Yuehong thought for a moment before saying, "Excluding the possibility that the surveillance footage back then was faked, the murderer should be hiding in a room around that route. If he's only at the Sea of Origins level, just searching the rooms on both sides of the route would suffice. If he had entered the Mind Corridor, we'd have to include the rooms on the other nearby streets in our search range."
The route referred to the route Mu Qingqing's father—Mu Renjie—took from home to the nearest public bathroom. It started with his house and ended at the spot where he fell to the ground.
"Why must we eliminate the possibility that the surveillance footage is faked?" Shang Jianyao asked in an unconventional manner.
