Xu Weilai remembered that Gu Yu said he was driving while she was calling him just now. She managed to associate something with this. Among the details that Wen Xiaoshan told her, she did mention that Li Huihuang drove her over to this place while she was drunk!
If he drove her over, that meant that his car would either be parked at the entrance of this place or he would drive directly into the underground parking lot. Maybe the cameras there caught him!
Xu Weilai was already a little dejected but instantly regained her motivation. She moved her mouse and started checking all the images at the entrance and the parking lot during that night.
At last, her hard work paid off. Xu Weilai managed to find an image.
