Hwansaengmusin

A martial artist is reborn as one of the Four Guardians of the Sun Palace, seeking vengeance. During a time of conflict, he wielded significant power and formed an alliance with Confucian scholars and six others to overthrow a corrupt emperor and nobility, aiming to create a society free from hunger. He installed Confucian scholars in positions of power and assigned his six allies as the Six Kings of the World to support them. However, the Confucian scholars and the Six Kings, fearing the growing influence of a particular Confucian scholar, conspired to kill him. The scholar was reincarnated as one of the Four Guardians of the Sun Palace, once again taking up his sword to pursue retribution.
