The Strongest Time Traveler Starts from the Son-In-Law

[Traditional historical fiction + slow heat + no system + high IQ + conspiracy + group portrait] Jiang Yuan woke up and found that he had really traveled through time. The son-in-law of a wealthy family, a wealthy banker, and a beautiful wife sounded like the beginning of Tianhu. However, he was framed as soon as he entered the house. Murderous plots were everywhere in the family. Most importantly, it was said that his wife, whom he had never met before, actually hit the husband... Faced with such an opening, Jiang Yuan could only look up to the sky and sigh. I originally just wanted to be a quiet son-in-law, but you insist on forcing me to play tricks, right?
