Zhao Yang spent the entire afternoon cross-referencing the transcripts and then re-interrogating the others, focusing particularly on Zou Lita and Li Jiahuan, aside from the six people who had just been released from prison.
Compared to the six regulars who were no strangers to police procedures, Zou Lita and Li Jiahuan were easier to catch off guard. More importantly, as the brother of Zou Liyu, Zou Lita held a unique status and presumably would not show bias towards criminals.
Nevertheless, no matter how Zhao Yang questioned him, Zou Lita insisted on sticking to the statements recorded in the transcripts without uttering a single unnecessary word. At this juncture, the fear of Zhao Yang wasn't the most crucial factor for Zou Lita; it was the pill that Zhao had made him swallow.
He was afraid of dying, so he dared not say anything. Had it not been for that pill, Zou Lita might have actually revealed something under Zhao Yang's interrogation.
