Financial elite Qi Yuan accidentally discovered a bronze compass engraved with mysterious runes while exploring a "ghost village" in western Zhejiang. At the moment of contact, a total solar eclipse fell. After the strong light passed, he actually traveled back to the Chongning period of the Northern Song Dynasty and possessed the son of a debtor farmer of the same name.
In this world where money matters, Qi Yuan relied on modern financial wisdom to resolve the family debt crisis, but was involved in the conspiracy of the landlord Wang Yuanwai and the county captain Zhou to secretly mint coins. What's even more amazing is that the bronze compass is actually an ancient "spring" that can sense money flow and predict economic trends, but it also accelerates the metalization of his body. In order to survive, he became a disciple of Master Lu, a coppersmith, and Afu, the son of a groom, and the three of them embarked on a dangerous journey to find the "Book of Duozhi".
In the secret realm of Tongguan Mountain, the truth of financial Taoism is gradually revealed: the prime minister Cai Jing tampered with the heavenly book, controlled the country's money flow, and even colluded with the Liao Kingdom to shake the country's foundation. Ah Fu's life experience and Qi Yuan's time travel are closely connected with the legend of the "Time and Space Gate". When the blood moon reappears and the bronze compass shines in the present world and in the Northern Song Dynasty at the same time, Qi Yuan must make a choice - return to modern life, or return to a thousand years ago and use financial methods to rectify the world?
This fantasy novel combines historical suspense, financial intrigue and time travel, uncovering the Taoist secret war behind the economy of the Northern Song Dynasty and exploring the eternal game of money and power.
