Surprisingly, it was Qin Yu herself who eased the tense atmosphere.
"Hah, no need to be so tense. I haven't broken any laws, and I barely know Zhang Yao. I only slapped her four times at the ceremony a few days ago. Well, not exactly, those four slaps were divided among several people, she only received one and was even thrown into a trash can. After that, we didn't have any contact. Even during the legal dispute that followed, I didn't show up. I feel sorry for her misfortune, and I'll cooperate if I can. So, have you determined the time of her death? You can ask me what I was doing at that time, and I'll check if I have an alibi."
Qin Yu, experienced as she is, seemed unperturbed by Zhang Yao's death. Her attitude was fair, and she didn't sound like a foolish wealthy child at all. The police then asked her for an account of her whereabouts over the past three days.
