It tells the story of Shen Du, a modern audit expert, who traveled to the Tang Dynasty and became the head of the Ministry of Household Affairs. With a pair of "auditing eyes" that can see through the fishy accounts, he was involved in a major corruption case. In a desperate situation, he stripped off the cocoon, brought down the corrupt man, and changed his life with his professional ability. From checking old grain accounts to rectifying the frontier army's salary bank, from implementing the New Financial Deal to being embroiled in party disputes in the court, Shen Du has been in the imperial money bag of the Ministry of Households every step of the way. He fought against powerful ministers, settled border towns, and solved strange cases. Finally, in the turbulent times when Wu Zetian came to power, he won trust with his excellent financial management skills. He became the prime minister, took charge of the world's wealth, and became the imperial finance minister with true "power over the world".
