Wuseong Dan, the man who ruled over the martial world with his fists alone. After unexpectedly losing a duel against two practitioners of the Demonic Way, he's reborn into the body of the wild child heir apparent of the affluent Silver River Merchants. Not one to leave debts unpaid, be they to his benefit or detriment, Wuseong sets out on his path of revenge in the body of Jineon Lee. Using his knowledge of martial arts from his past life and the wealth of his current life, he only has one goal: get stronger and kill those who killed him.
