The General's Son-In-Law

Behind every successful woman there is a great man. Due to a car accident, he time-traveled into the body of a handsome man and became his wife's son-in-law and the most solid support behind his wife. He cultivates talented women, occasionally works as a copywriter, but accidentally sets off a book buying frenzy. When modern people travel to ancient times, what kind of brilliant sparks will they create? "I don't produce culture, I'm just a carrier of culture."
