Relying on advanced insight and extraordinary courage, Chen Dong exposes the conspiracy on the spot and clears his grievances.

Facing layer upon layer of framed plots and life-and-death gambles from opponents, he breaks through by leveraging momentum, seizing the trend of the era to make a counterattack and rise. Rushing toward a passionate career while guarding sincere love, he ultimately transforms from a rural good-for-nothing into the wealthiest man of a generation under the waves of the era.
