Description:

One day, KangWoo suddenly fell into Hell, with only a strong desire to survive and the Authority of Predation on him. All the way from the 1st to the 9th Hell, he devoured hundreds of thousands of demons, until even the Seven Archdukes finally knelt before him. “Why do you wish to return? Do you not already possess everything in Hell, my lord?” “What exactly is it that I have?” There was nothing to eat, nor any entertainment! Desolate lands and hideous demons were all that filled Hell. “I’m going back.” After ten thousand years in the 9 Hells, he returns to Earth at last. (Source: KakaoPage, translated)
