On the morning of the incident, at 7:22, you went to the unit where the victim lived, and then at 8:02, you both left together. And there were no fingerprints on that cake box, correct?"

If there's nothing, I'll go over and compare myself. Oh, I need to collect blood samples and fingerprints from Xu Qingshu first and hurry them over."
Xu Dayuan nodded. Zhou Ning moved closer to the one-way mirror. Next door, Mr. Zhao, carrying a case, went to draw blood and collect fingerprints. Xu Qingshu was very cooperative.
