Lin Xiaochuan, a modern high school underachiever, is scolded by his teacher for getting zero in math. In anger, he smashes an ancestral ancient book and transmigrates into the "useless legitimate son" of the Zhenguo Duke’s mansion—weak since birth, despised by his family, and even forbidden from taking the imperial exam. When the palace’s Temple of Heaven construction faces a crisis: the main beam is three feet askew, and no one can fix it. The emperor decrees, "Whoever solves this will be named Zhuangyuan (top scholar)!" Lin Xiaochuan uses the Pythagorean theorem, draws a right triangle, and calculates the exact correction. The beam straightens immediately! The emperor is astounded and grants him the Zhuangyuan title on the spot! But soon after entering the court, he’s assigned to investigate grain transport corruption and find the missing Princess Changle. With modern criminal investigation skills to track clues, physical buoyancy to retrieve sunken stolen silver, and chemical test paper to detect poisoned wine… As he breezes through challenges, he uncovers a massive conspiracy behind the corruption—Princess Changle’s disappearance is tied to the ancient book that caused his transmigration?
