Chu Xuan transmigrates into the body of the young master of the bankrupt Lanyue Brothel, with only one goal in mind: paying off his debts. Unexpectedly, he binds himself to the Pleasure World Overlord System, which grants him unlimited funds that can only be used for business expenses. To turn a profit, Chu Xuan has no choice but to introduce a variety of generous benefits and treat everyone well. Gradually, Lanyue Brothel becomes a paradise for women, attracting an enemy princess, a demonic cult enchantress, a charming princess consort, and a valiant daughter of a military family. However, its growing influence soon arouses suspicion and fear at court.
