Chen Zhijie, a modern financial auditor, traveled to the Southern Tang Dynasty in 961 AD and became a minor warehousing official at the end of the ninth grade. He knew clearly: Eight years later, Zhao Kuangyin destroyed the Southern Tang Dynasty, Jinling City was destroyed, and Li Yu became a prisoner. What's even more fatal is that on the first day he took office, he discovered a shocking deficit in the national treasury - someone was systematically cooperating with the Northern Song Dynasty to empty out the Southern Tang family wealth. Han Xizai discovered his talent and pulled him into a secret economic defense battle. Relying on modern financial knowledge and supply chain thinking, the protagonist gradually climbs from an accounting clerk to the core of decision-making, amid the ghosts in the imperial court, the economic stranglehold of the Northern Song Dynasty, and Li Yu's genius and stupidity. But every progress is accompanied by the inexorable passage of the countdown - every day he buys may be reset to zero in the next political earthquake.
