Dungeon Talchuri Neomu Himdeulda

Go Insung did not pass onto hell or heaven after suddenly dying, but instead onto a dungeon. A place in between the afterlife world and the living world. It’s a dungeon with a broadcasting system. While being watched by the numerous dead of the afterlife, Go Insung has to clear the dungeon with the other challengers in order to escape.
