Darling, I Really Don't Want to Be the Top Scholar

Transmigrated as a live-in son-in-law, my wife is a stunning beauty, but she looks at me like I'm a piece of rotten wood. 'Husband, pass the imperial exams, or my Yun family will be devoured,' she sighs. I, a modern PhD in history and sociology, look at the 'Confucian classics' and simple math problems, lost in thought. Do I even need to study this? Fine, to repay her life-saving grace and not disappoint my beautiful wife, I'll reluctantly... dominate the rankings.
