Modern youth Chu Xuan time-travels to Great Qian, takes over a bankrupt brothel, and activates the Overlord of Wind and Moon System in a desperate situation, gaining unlimited operating funds. He breaks the dregs of old-style romantic establishments, creating Lanyue Pavilion, a top elegant venue selling arts rather than bodies. He redeems fallen talented women, low-class refugees, and orphaned daughters of military generals, gathers street factions, and builds a top intelligence network. Stirring up the capital's business circle and court layout, and maneuvering through the princes' struggles for the succession, he steps by step counter-attacks from a despised brothel owner into the Overlord of Wind and Moon who controls the capital's grey layout and shakes the court. Even when framed for treason by nobles, he still stands firm in the capital and masters the winds and clouds.
