Shen Qingwan, the modern financial director, traveled through time due to a plane crash and became the legitimate daughter of the Shangshu Mansion. With fifteen years of financial and taxation expertise, starting from the case of a horse falling from the back house, she teamed up with her brother Shen Qingci to bring the murderer to justice. She participated in the imperial examination and was awarded the top prize in high school. She impressed the emperor with her "On Financial Use" and was awarded the title of imperial envoy and inspector. She was also given a sword by Shang Fang. From Huaizhou to Jiangnan, from Lingnan to Jiannan, she investigated and anti-corruption all the way, overthrew Prime Minister Zhao Qian, faced the Queen Mother's deal, and finally uncovered Prince Ning's conspiracy. The emperor adopted her plan and established the Central Taxation Department to unify the tax system, vertical management, and cross-auditing, creating a prosperous age of Yonghe. Ye Qingcheng, the young master of the No. 1 Sword Shop in the world, protected her with his sword. They stayed side by side for ten years, not expressing love but trusting her with their lives. After his success, Shen Qingwan resigned and went into seclusion, wandering around the world with Ye Qingcheng. With numbers as her sword and justice as her shield, she blazed her own path.
