Start with a Fraud Case

A criminal police trace expert investigates a fraud case against the elderly, but starting from an ancient copper coin in the hands of the deceased, he leads to an old case from 30 years ago, the mysterious plum blossom imprint, the Shouku family and the legendary Five Dynasties Treasury. As the investigation deepened, he discovered that this fraud had another purpose from the beginning, and his father and life experience had already been involved in this secret that had lasted for decades.
