Lin Fei, the all-powerful Dragon Lord of the Dragon Sect, was ambushed eight years ago and left stranded in Jiangcheng, on the brink of death. After mistakenly identifying the person who saved his life, he married Su Ruoxue, the eldest daughter of the Su family. After their marriage, Su Ruoxue arrogantly demanded a divorce. Lin Fei promptly reclaimed every gift he had given her, leaving her with absolutely nothing. As he reinvestigates the events of that fateful year, Lin Fei discovers that his true savior was Su Wan, the adopted daughter who had been driven out by the Su family. He fiercely protects Su Wan, deals with the provocations of the Su family and the Black Dragon Chamber of Commerce, purges corruption within the Dragon Sect, and humiliates one villain after another. In the end, he appoints Su Wan as the Dragon Sect's matriarch, finally fulfilling the promise he made eight years ago.
