The strongest warrior of the Great Qian Dynasty

A legendary soldier, transported to the Great Qian Dynasty, became a servant in the Changning Marquis's household.
But something seems off about this servant's job?
The eldest young lady wants me to be her cauldron, the second young lady wants to talk to me about poetry, the third young lady wants to practice martial arts with me... Hmm? The ninth madam even wants to steal my cauldron!
Alas! The Marquis is dead, leaving behind nine beautiful wives and seven daughters. I, a mere servant, have unknowingly become the head of this household. It's unbearable; even drinking goji berries every day can't keep me afloat!
