The Mystery Behind the Extinguisher

"Police officer, even though our robot has a camera, it doesn't go near the escalator. It only goes back and forth within the restaurant area!" the worker explained to Zhao Yu. "So, it wouldn't have been able to record the place that you were talking about! Plus, its speed is extremely slow and it has a special function that allows it to avoid passers-by. Hence, it was obviously the little boy's fault! You should tell them to compensate us!"

What Zhao Yu intended was for the restaurant to transfer out the video before the murderer burnt the five million ransom, in order to see if the robot's camera had recorded anything suspicious. He felt that, since he had gotten a Qian hexagram that day and the side quest had led him there, it was most likely related to the burnt ransom incident.
