After a car accident, financial whiz Jiang Wanyi is forced to bind herself to a “Gold Coin Space.” She can return to the modern world only after earning thirty trillion gold coins. Transmigrated into the Kangxi Emperor's harem as a Han Bannerman noblewoman, she uses an abacus to investigate corruption with one hand and builds factories and opens shops with the other. Her glassworks outclass Western goods, a postal network links trade routes across the empire, and her cosmetics become all the rage in the Forbidden City. Kangxi breaks with ancestral traditions for her and silences her critics, letting her stir up the court's political waters while placing the keys to his private treasury in her palm. “My empire has room for your ambition.”
Yet every time her coins increase, history shifts a step further. Crown Prince Yinzhen joins her in designing the first postage stamps, Yinzhen learns her cost-accounting methods, and Yinzhen follows her around, begging to invest in her bank... The succession struggle among the nine princes hasn't even begun, yet all nine have become her close friends in business. When Consort De's poisoned cup meets a warning from her Space, and Songgotu's schemes ensnare her merchant ships sailing abroad, Kangxi presses close to her neck and murmurs, “What does earning thirty trillion matter? I want you, in every life to come.”
In this deadly whirlpool where wealth and imperial power intertwine, can she hold on to her principles?
Will she bask in the emperor's exclusive devotion and live in luxury, or risk her life to defy fate and change history?
A legendary business war spanning past and present, and a love story steeped in blood and beauty, now begin.
