The Most Capable Servant in the Mansion

A modern office worker travels through time to become a lowly servant in a Tang Dynasty minister's mansion. He binds a wealth system and uses modern purification techniques to make white sugar, salt, and strong liquor for profit. He encounters a gentle second miss, a pampered noblewoman, and a benevolent female doctor, leading to hilarious daily interactions. He repeatedly suffers underhanded schemes from a cunning steward but always turns the tables. He makes money in both the marketplace and among the elite, with warm interactions among multiple female leads. A pure urban business comedy with no fantasy elements.
