During the Yongle period, chaos arose in the depreciation of banknotes. Lin Yuan, the son of a Hanlin Academy scholar, unexpectedly got involved in a banknote conspiracy related to the fate of the Ming Dynasty due to his father's mysterious death. From the strange transactions of the Yufeng Bank to the mysterious records of Ci'en Temple; from the life-and-death chase at Jubaomen Pier to the secret treasure of the Dragon Palace on Turtle Island Reef in the South Sea, he holds half a jade pendant and a broken jade seal and struggles to survive amid the pursuit of the Jin Yiwei, the rebellion of the vassal king, and the infighting of the aristocratic families.
Liu Yan's enchanting calculations, Su Mingyue's righteousness and evil, Xu Qingyao's heroic figure, Jiang Wanqing's gentleness and wisdom, and several strange women walked hand in hand with him, secretly developing feelings in the whirlpool of power and intrigue. As the "Shuilongyin" treasure left by Shen Wansan comes to light, he is shocked to realize that he is actually a bloodline of the Shen family, and behind this chaos in banknotes lies a shocking chess game that has been laid out since the time of Zhu Yuanzhang - banknotes are not only currency, but also the key to controlling the world.
When the prince's ambition, the Han king's conspiracy, and the Song family's dormancy gradually come to light, can Lin Yuan unlock the secret key to the treasure and rewrite the wealth structure of the Ming Dynasty? In the confusing situation where money and power are intertwined, how will he protect the people he loves and write his own counterattack legend?
