"How did it come to this..." Xun Tianhai gritted his teeth fiercely, clenching his fists as his temple pulsed irritably.
Jiangli looked at Ya Xingbo and asked, "Did Gu Hai ever separate from you guys? Did he go off on his own, go to the bathroom? Do anything special that none of you did?"
Ya Xingbo was Xun Tianhai's subordinate, and he had heard Xun Tianhai mention Jiangli quite a few times, so he was somewhat polite to her.
Although puzzled by Jiangli's question, he began to answer.
"He and Xie Yulan have been together all the time, I don't think he acted alone. He went to the bathroom during the day, but I didn't hear about it at night. After we left the cafeteria, we stayed together looking for clues in the building but found nothing, so we returned to the office to rest."
Jiangli asked again, "Did he do anything before going to sleep?"
Ya Xingbo recalled, "No, he just drank some water?"
