I didn't care at all about the threats of the demon king.
After all, it wasn't as if I would be heading to the same upper realm as the demon king in the first place.
Even if I was, I wouldn't be afraid if I had to face the demon king since I had something that no one else had in this world.
I had my special system that would protect me if anything went wrong.
So there really was no need to fear the demon king.
After the throne had been destroyed and most of the demonic cultivators and demons had been taken care of, there was nothing left for us to do here.
There was still the Demon Slaying Conference happening, so there were others to take care of the demon cultivators and demons that were left in this Demon Valley.
