I'm Shen Yan, 28 years old, with a PhD in history. I've spent over a decade researching the imperial examination system of the Ming and Qing dynasties. When I open my eyes, I've transmigrated into the body of a five-year-old poor boy in ancient times. Our house is bare, the entire village looks down on me, and I can't even complete a matching couplet. But my mind still holds an entire empire of knowledge about exam-setting patterns, examiners' preferences, and unwritten scoring rules. I know it all. The problem is—I'm only five. This body gets breathless after walking less than three miles. So I can only play dumb. Everyone thinks, 'That child tries hard, but his talent is mediocre.' Until the provincial examination results are announced, and I place eighth. From a poor family to a powerful minister, I make every move at exactly the right moment. Because what I'm best at is controlling my score.
