Earlier, Xiang Kun had asked Alice to search online for the identity of the so-called "Vampire Patient" at the Third Hospital based on his conjectures. Alice successfully found substantial information that seemed dependable and accurate to Xiang Kun - which later proved to be correct in his conversations with Old Xia; he had indeed found the right person.
Since he'd already revealed his hand to Old Xia, he could be upfront about his suspicions about the "Vampire Patient". With an insider like Old Xia assisting him, there was no need for Alice to continue her investigation.
However, at that time, Xiang Kun didn't ask Alice to cancel her task. The further investigation into the "Vampire Patient's" information was still ongoing and was a highly prioritized task.
Now, upon checking Alice's task progress, Xiang Kun was astonished to find that the medical history of the "Vampire Psychiatric Patient" residing in the Third Hospital had actually been dig up by Alice?!
