The Son-In-Law Taught Him the Number One Scholar

He became a son-in-law through time travel and was looked down upon by the whole clan? It doesn't matter, he was a gold medal trainer in his previous life. Others laughed at him for being a softie, but he turned around and taught all the "waste" in the clan to become academic masters in the imperial examination - eight-legged template, policy framework, and current affairs questions. From the county examination to the palace examination, he crushed the noble families all the way. When the news of the success of the number one scholar spread throughout the world, the clan members knelt down and begged him to join the family tree in the ancestral hall. Who says a son-in-law can't teach him to become a champion? This world's cultural context will be reopened by him!
