In fact, Huo Yichen didn't find any key clues in the small restaurant.
It was better to say that after he checked in private, he could only confirm that Murong Qiao had indeed been to this place. However, firstly, the surveillance video couldn't confirm any effective information. The computer only had a black and white screen that was clearly broken. Secondly, there was probably something on the notebook at the front desk. Unfortunately, it was deliberately torn off. Clearly, they didn't want to leave any evidence for him to track down.
The situation was at a deadlock.
Huo Yichen could only return the way he came and flip over from the window he had broken. Then, just as he was about to leave, he realized that there was a back door behind the small restaurant.
