It's an origin myth/fable, NOT a history channel special. The Hanja for Hae MoSu means "Son of Heaven"! As much as I enjoy watching this show, I can't believe how sloppy some of the English sub-titles are. MBC should be ashamed.
i haven't watched as far yet than E68, but i already
know that nothing is going to save Taeso or Puyo

Soooo... some box, just sitting on top of a mountain for centuries was never found by anyone else in all that time until jumong comes along. Yeah... riiight. Wouldnt Bigeumsun make for a excellent sorceress to jumongs nation?
