Five years ago, the Lin family was exterminated by four major families. After being rescued, the young master Lin Jiuxiao returned as the top powerhouse "Hidden Dragon". He unexpectedly formed a bond with Ye Bing, who was drugged. He lurked beside him under the pseudonym of a driver. While covering himself with a Nuo mask, he took revenge one after another at wedding banquets and birthday banquets, dismantling the power of the four major families. At the same time, he secretly investigated the mysterious black hand behind the family murder case and the secret of the ancient dragon-shaped jade. During this period, he lived with Ye Binning, hot-blooded policeman Huo Ling'er, and lively girl Qin Wan'er, dealing with friendship and murderous intentions. He finally uncovered the conspiracy of the four major families relying on high-level forces, and embarked on the road to fight against the mastermind behind the scenes.
