Oh Kang-Woo suddenly fell into Hell one day. The only things he had were his desire to live and the Authority of Predation. He devoured hundreds of thousands of demons from the First Hell all the way to the Ninth Hell, and even made the seven princes of Hell bow down to him. "Why are you trying to go back? You already have everything that you could possibly desire here in Hell." "I have everything? Like what?" There was nothing to eat or enjoy! The only things in Hell were desolate lands and hideous demons! “I’m going back.” He finally goes back to Earth after ten grueling millennia.
