"Well, aren't you funny?" The demon laughed at Michael's response.
However, its laugh quickly faded, replaced with a serious expression, a stark contrast from its easygoing self just mere moments ago.
Now it was just staring at Michael in silence with clear malice in its eyes.
I don't think you need an expert to tell you that you managed to piss off the demon, yes?
'No shit.' Michael did not back down and continued holding eye contact with the demon before him, but he could not quite tell what the system was talking about, it felt like just a stronger imp in all aspects.
Its body looked like it was made out of pure mana, however, there were a few places where there was a bit more mana than normal.
And the system further confirmed his suspicions.
They have a core in their bodies, if you find it and destroy it, the puppet dies. The same applies to demons, but if you manage to destroy a demon's core, you can kill it fully.
