"I'm just guessing. As the three victims are all killers, I have reason to suspect that the perpetrator might also be an assassin. At the very least, he will have a dark network channel.
"This should be the way he chose his targets. Although I don't know why he chose these three killers as his targets for the time being, I discovered something strange if I investigate in this direction." As he spoke, an image appeared on the dark web. "According to the information provided by my informant, a killer's ranking has been rising on the dark web recently.
"This assassin's nickname was 'Macheteman'. He rose so quickly that he had already formed a considerable influence in the underworld. Although there was no direct evidence at the moment, I had reason to suspect that this Macheteman might be the murderer we were looking for. The reason why his ranking rose so quickly is because he killed three A-rank killers in a row."
