Mu-Geuk Geom

He is the second son of Woojin Geom. He was an incompetent young master who could not properly compete with his older brother and was easily deprived of the position of successor. However when he lost everything from his father to everyone around him he decided to use The Great Regression Technique. After many years he gathered all the necessary materials for the regression technique and decided to return to the past to take revenge on Moogi Hwa.
