Hyunmoo Kang is a miner scraping by in a world where those with the right talent can make millions as hunters in dungeons. One day, he inherits a mysterious hearthstone that magically transports him to a place called Hell, where he quickly dies-only to regenerate. In Hell, he hones his skills, builds talent, and hoards items that pay handsomely in his world. As Hyunmoo spends more time in Hell, he starts to wonder how this place came to be and most of all... how it connects to his own world.
