Demon king in the hunter society

My whole body was painful and my head felt like spinning, if i just had seen that trap i wouldn't had lost everything!

my eyelids was getting heavier as i was slowly falling asleep in the sealing spell that was casted onto me, luckily i was able to weakened the seal before it took effect, but i still fell into a deep coma for many years. I thought I was never going to break the seal until I heard voices, human voices
