The Death Group Chat Administrator spoke in a relaxed tone about something extremely terrifying.
Han Fei had played the 'spot the difference' game before, but the pictures provided by the administrator depicted a person being tortured, and the changes or differences were all inflicted upon his body, which was utterly horrifying.
For regular people, one extra look at this photo would cause nightmares, yet the administrator generously gave Han Fei one minute to spot the differences.
To the administrator's surprise, it only took Han Fei ten seconds to accurately point out twenty-five differences in the picture.
This surprised the administrators. They had a complete internal evaluation system where the number of seconds taken to find differences could assess the level of one's inner perversion.
