After a pause, Xu Huan added coldly, "That morning, after giving the medicine to other patients who needed it, the rest of the special medicine was stolen. According to the staff on duty at that time, no one entered the pharmacy that day. Besides that, I've seen the surveillance video of the hospital too. There's nothing abnormal. I suspect that someone had tampered with it."
Huo Xuan quietly listened to Xu Huan before raising his hand to pinch his glabella. He asked, "Do you have any clues from the research institute?"
Xu Huan frowned and slowly sat up straight before continuing, "The research institute's medicine was taken away by a mysterious person of unknown origin. The person who was sent to investigate said that the entire research institute knew that he had taken it, but no one said who it was. This matter sounds a little tricky."
