A quasi-prestigious university history graduate who was born with a mysterious golden "dragon head mark" on his right arm discovered the shocking secret of the mark on his arm by completing his history graduation thesis (he was actually one of the dragon mark people selected by the golden dragon mark!). From then on, he and his partners embarked on a path to explore their mission and past and present lives. Is the dragon mark person who suddenly appeared with a dark purple dragon mark an enemy or a friend? What exactly will be the mission of the Dragon Mole Man? ... A wonderful imagination, adventure, supernatural, and science fiction all in one!
