I Have Been Called The Idiot Son Behind My Back. But I Remembered Memories, And I Can Use The Abilities I Had In My Past Life. So I Will Make Use of Major Online Stores Like Am**on And Aim for a Slow Life for Now - 44

By the way, what I’m currently searching for is a serial killer. The guild’s posters described it as “killing prostitutes (streetwalkers) in succession.”

So, using the Dark Magic Rank II [Dark Conceal] that my master taught me, I maneuver through the darkness, searching the alleys.

Then, in a certain corner near the slum area, I found a place where several women resembling prostitutes were standing at the edge of the road. I decided to stake out there.

And after waiting for about an hour, a man who seemed like the target showed up, which I must say was quite fortunate.

To be honest, I thought I would need to stake out for several days, so it’s a relief from my standpoint that the target appeared so easily.

On the other hand, from the perpetrator’s perspective, it also indicates that it has become a habit.

I wonder how many prostitutes have fallen victim so far…

Moreover, considering the discrepancy between the number of murders this guy is likely involved in and the number of prostitutes disappearing daily, it’s highly probable that he’s either selling them to slave traders in secret or selling organs for experiments or drugs.

Therefore, the note in the guild’s request details suggests the existence of a fairly large human trafficking organization in the underworld.

Of course, since the opponent understands what is being requested by the guild, it’s likely that those who are doing the riskiest job of “luring out prostitutes” are just low-ranking members of the organization, and catching them wouldn’t lead to a fundamental solution.

So, I decide to let the one sweet-talking the prostitutes right in front of me slip away.

The magic my master taught me, called [Dark Conceal], allows me to move in the shadows or darkness, making it quite effective for tailing or lurking like this.

Such magic is usually passed down within families and kept secret, so even though I’m a slave, I can feel the depth of my master’s generosity for teaching it to me without hesitation.

Moreover, I don’t understand the mechanism behind learning magic, but it’s directly engraved in my brain. In the next moment, after using a dedicated learning item, I was able to activate [Dark Conceal], which was also surprising.

My master said that in the previous world, he remembered the tools and knowledge he used and could use them by taking them out of storage. Seeing my master, who possesses such power and tools but uses them not for evil but to help the neighboring Lorraine family, I felt strongly that I want to use the power my master gave me without shame and make it the guiding light of my life from now on.
