The best Korean adventure TV show I have ever watched... and still watch 😂 LOL.(I have watched it like 5 times from the 1st episode to the 81st episode)... though there were some minor mistakes when editing/directing the TV show. For instance in episode 56 minute 1 Microsecond 25-27, we clearly see a modern day car and other people [presumably those directing the TV show] in the background.
