Choegang Dungeon-eul Wihayeo

Chiu Kang, known online as Kang Chi, is one of the best players in DC. To him, the real world feels dull and inefficient, so he pours everything into mastering the game. Yet... even at the top, life feels hollow. That all changed one day on his way home from the internet café. After a sudden accident, he wakes up not as Chiu Kang—but as Kella Caldern, the Demon King’s son.
