Island Silver War: 1940

In the isolated island of Shanghai in 1939, the smoke of gunfire could not contain the undercurrent of the financial battlefield. Chen Mo, a staff member of the Central Bank's Foreign Exchange Department, possesses [numerical intuition] - numbers turn into geometric totems entrenched by poisonous scorpions in his eyes. This talent allowed him to be the first to see through the monstrous conspiracy of the Japanese army's "Sugi Agency": four billion counterfeit banknotes are tearing apart the country's economic lifeline. When the blood of his mentor Zhou Muyun spilled out the password "Gold in Paper" on the streets of the concession, Chen Mo stepped into the whirlpool alone. From the case of counterfeit banknote ink tracing the origin of silk silk to the black market exchange rate battlefield to defeat the silver dollar hunt with mental arithmetic; from the life-and-death game of deciphering the "Sakura Order" secret message, to the shocking explosion of the underground counterfeit banknote factory in the French Concession Hospital... The abacus and bullets fired at the same time, and the account books and spies flew together. The cold digital hunter Chen Mo, together with the courageous war reporter Su Manqing, deal with the shrewd Japanese Army Major Yoshida Akira and the bloody silver dollar dealer "Iron Abacus". Using finance as their blade and cryptography as their shield, they waged a smokeless war between the artillery fire of the Battle of Changsha and the negotiating table of Bretton Woods. In the financial espionage war in Shanghai in the 1930s, bank employees used the Fibonacci sequence to decipher the codes of counterfeit banknotes. Amid exchange rate fluctuations and scorpion secret orders, they protected legal currency at the cost of their retinas - more hardcore digital games than "Insidious" and more historical depth than "Wushuang".
