For the detectives at the Lin'an Police Station, Professor Zhang Qiren's manner of death was exceptionally gruesome. After all, hanging a person from the ceiling and slitting their throat to bleed them dry was truly a rare occurrence!
However, amidst the detectives' shocked expressions, Lu Yu remained remarkably composed. The scene before him was all too familiar!
At this moment, the memories in his mind turned into images, appearing vividly before Lu Yu...
In a dim, eerie dungeon, a man was suspended from the ceiling. A man in a black uniform, with a lean and agile physique, held a sharp dagger, lightly tracing it over the throat of the hanged man. With each stroke of the dagger, another bloody mark appeared on the man's throat!
"Prisoner No. 32, you're quite special. Now you have two choices: either serve us or end up like this man!"
