"What do you mean by that?" the rich second generation frowned and looked at him, "During the blackout, everyone was at the electrical box, and you came over after hearing the noise, too. Who could have possibly killed someone else?"
"I've checked," Xu Huo said, "The shelf that fell just now must be the one next to the hot spring pool. Du Lanlan and Xia Guo, neither of them even cried for help before they were killed. It's very likely that the killer was much stronger than they were, and there aren't many signs of struggle around."
"Are you saying the shelf could have fallen by itself?" Wan Zhikang gave him a look that read, don't take us for fools.
"It might have been knocked over by accident, or it could have been the wind. With so many uncertain factors, how can you be sure that someone was here when the shelf fell?" Xu Huo said meaningfully, "Game props can also be used to create an alibi."
