Manga I Am The Sorcerer King

The monster attack on humanity began ten years ago, when hordes of monsters rushed from the space-time rift. It would seem that the chances of humanity are tending to zero, if it were not for the power that they discovered, which allowed them to hunt monsters and kill them. Thus began the hunt for monsters for financial gain and fame. Lee Sung Hoon was forced to become one of the monster hunters when his mother became seriously ill, as he badly needed the money. He became a decoy for monsters, helping hunters kill them every 4 months. However, one day the monster severely wounds him, because of which he recalls his past life. So he recalls that he was the most powerful sorcerer king with tremendous strength. From that moment on, his life changes beyond recognition.
