I left the building, holding the pen in my hand, examining it as the moonlight pierced through the clouds above and illuminated the road ahead. This piece… a system piece. I don't know exactly what type it is or what kind of authoritative power it contains, but from what I just witnessed, it's capable of reanimating corpses. It might possess even more abilities.
I don't yet know how I'll make use of it, but keeping it seems like the smartest choice for now. I'll definitely find a way to use it just like I did with the playing cards. I slipped it into my coat pocket beside the leather notebook and kept walking.
