While reading Xiang Kun's document, which recorded various mutation data and characteristics at different stages, Mr. Liang was simultaneously comparing it with the various life trajectory records of Xiang Kun after he transformed into a "blood-eating creature" on July 11th of the previous year, collected by "Tyre".
These records included text, related data, photos, videos, and even some chat records and screenshots from social media.
Although they had only just started to investigate and monitor Xiang Kun, in modern society, digital recording devices can be found almost everywhere. As Xiang Kun had not completely severed his original societal connections and still predominantly lived in urban areas— even in Chongyun Village, his regular place of residence that had been filled with surveillance after his transformation—there were plenty of digital records left behind.
