[The Stigma of Darkness has successfully absorbed Death Mana.]
Only the system message before my eyes confirmed that the Stigma of Darkness had absorbed something.
Death Mana? I don't know what it is.
For now, I ignore that.
I have to quickly clear the guards of the other Black Box Organization headquarters before anyone notices my movements.
But before I stepped in to kill the others, I took out the sword hidden by the guard of the Black Box Organization headquarters that I had just killed.
With the preparations finished, I started running toward the other guards. Luckily, because of their great distance, they didn't know that I had killed one of them.
Therefore, I approached them one by one, covered their mouths, and strangled them until no bad breath came out of their noses or mouths.
"Ugh!"
"Ack!"
"Mm!"
Not all of them were pretending to be drunk bums. Many of them just sleep on the side of the road, watching from the roofs, or even hiding in the garbage dump.
