Obviously, I watched this drama because of Song Joong Ki., my second time seeing him in a non-dashing and undesirable look after in "My Werewolf Boy". I believed this drama was either the first or one of the few that produced a reimagination of the lives of the earliest people; It was fascinating to hear their dialect, particularly on the kids' cast, overflowing with talents for them to memorize and pronounce it The build-up of the story was tortoise-like but I had to press down my standards since it was a chronicle, needed a long and detailed narration as precedence. On the contrary, your eyes will be delighted by the sight of nature's beauty and the pride of its cinematography.
