Traveling through the Qin Dynasty, Zhao Yuan was burdened with huge debts at the beginning and his life was hanging by a thread. At a critical moment, he awakens to the mysterious "square hole copper coin" space, which contains an inexhaustible gold treasure house. Facing the pressure of debts from officials and oppression by powerful men, he used gold as a shield and wisdom as a spear to calmly deal with Heibingtai and local forces.
From a dilapidated thatched hut to the establishment of "World Bank", Zhao Yuan used gold as bait to acquire rare treasures, which not only resolved many crises, but also quietly leveraged the wealth structure of Qin. He made friends with powerful people, recruited talents, spread his bank business throughout the counties, and became the "invisible richest man" behind the scenes.
However, the accumulation of wealth also attracts greater covetousness. When the situation in the court changes and all forces are eyeing this piece of fat, Zhao Yuan must work step by step amidst overt and covert struggles. He not only wants to protect his family, but also wants to use his tens of thousands of wealth to inject new economic blood into this iron-blooded empire and write his own legendary chapter in the torrent of history.
