Modern financial auditor Chen Zhijie transmigrates to the Southern Tang in 961 AD, becoming a low-ranking, ninth-grade official in charge of storage. He knows exactly what is coming: eight years later, Zhao Kuangyin will destroy the Southern Tang, Jinling will fall, and Li Yu will become a prisoner. More ominously, on his first day in office, he discovers a shocking deficit in the national treasury. Someone is systematically helping the Northern Song strip the Southern Tang of its wealth. Han Xizai recognizes his talent and draws him into a covert economic defense campaign. Armed with modern financial expertise and supply-chain thinking, the protagonist rises step by step from a lowly auditor to the heart of decision-making, navigating palace spies, the Northern Song's economic strangulation, and Li Yu's mix of genius and incompetence. But every step forward comes with the merciless ticking of a countdown: any day he buys could be wiped out by the next political upheaval.
