Three hundred years ago, the Zhang Xianzhong River estuary was flooded with silver, and Li Dingguo established a legacy alliance, which enabled the four major families of Zhang, Yang, Yuan, and Li to do business for generations, using treasures as the basis and funds once every ten years, as a secret inheritance to fight against the Qing Dynasty and restore the Ming Dynasty.
In 1900, when the ten-year promise came again, the head of the Yang family discovered the secret of the Li family's collusion with the Qing court and was brutally silenced. His daughter, Yang Huaiyin, was in danger and took charge of the family. She was in charge of the bank and dealing with the troubled times while investigating the truth behind her father's murder. However, she was separated from her beloved Yuan Shi'an, the son of the Yuan family, because of her ancestral precepts. Zhang Jingxing, the son of the Zhang family, silently guarded the family, while Li Yanzong, the eldest son of the Li family, suppressed and destroyed the family under a pseudonym, forcing the Yuan family to disfigure and go into exile, the Zhang family to flee, and the Yang family to go bankrupt and dormant.
After eight years of accumulation, Yang Huaiyin returned with a changed name, Yuan Shian, to take revenge and use finance as a blade to create a fatal situation. From the Cold War in the late Qing Dynasty to the turmoil of the Republic of China, and then to the Japanese invasion of China, the three-hundred-year alliance has already changed. The Li family has become a profit-seeking traitor, and the second son even colluded with the Japanese invaders to launch a financial war.
In troubled times, family feuds and national calamities intertwined. Three generations went through a baptism of blood and fire, and finally returned the Shen Yin Secret Treasure and all assets to their home country. A century of grudges finally disappeared with the mist of the Silver Sea.
