Before the Suizao War in 1939, the current situation in Xianjiang City in northwest Hubei was turbulent and the forces of all parties were complicated.
Liu Muchu, a young man who had returned from studying abroad, was inexplicably attacked by gunmen on his way home with his father. But the other party is obviously not a robbery or vendetta against the rich Mr. Liu.
After a lucky escape, Liu Muchu immediately realized that the interception might be aimed at him. To be precise, the other party might want to get a pen back from him.
There was nothing special about the pen, except that there was a unique bug pattern engraved on the outer shell. His father told him that this was a "green clam", which in legend has the meaning of eternal wealth, so many banks have used it as a symbol since ancient times. The Liu family and his son did not realize that Liu Muchu had been involved in the "Qingfu Plan" formulated by the military commander to fight against the Japanese counterfeit currency. Counterfeit banknotes gradually spread in Xianjiang City, and the Liu family was also affected.
With the war approaching, Liu Ji's Hanxin Bank took over the military pay acceptance business, but all the millions of cash "turned into" counterfeit banknotes after being transported back to the division headquarters. Different from the previous petty troubles with five-yuan notes, the reappearance of counterfeit banknotes this time has directly shaken the foundation of Liu's industry. When the Liu family was in turmoil, Liu Muchu, who had no intention of inheriting the family business, had no choice but to step forward and try to find out the real murderer from the conspiracy behind the counterfeit banknote case.
