No. 1 in the World, but I Am Mr. Accountant

In the C-shaped account room of Yangzhou Huitong Tianxia Bank, there is always an inconspicuous old accountant sitting. Xie Ping'an, over fifty years old, is slightly hunched, wears a pair of polished reading glasses on the bridge of his nose, and is always wrapped in a semi-old gray cloth. His hands that fiddle with the abacus are always slightly trembling, and he looks like an old master whose edges have been smoothed by time. No one would associate this third-class bookkeeper, who would be fined with a monthly fine for miscalculating a penny, with the Cangming Sword Master who was famous in the world thirty years ago. At that time, he was a legend who was at the pinnacle of swordsmanship, moving all the nine provinces with his sword, but once he retired, he became a mere mortal in the market, busy checking accounts. But this ordinaryness is just the first layer of his disguise. In the middle of the night, he is the night accountant who corrects injustice and punishes corruption; in the ledger room, he can deduce the direction of money flow from the lines of running water, and detect people's calculations from trading habits. When the Jinyu Alliance uses business as its blade and attempts to control the martial arts landscape with money, when the salt merchant smuggling case leads to clues to a thirty-year-old case, when the orphan Lin Qingyue of his best friend is involved in the conspiracy, and the apprentice Zhao Xiaoman is kidnapped for spying on the secret, Xie Ping'an's peaceful life is completely broken. He was still sitting in the accounting room fiddling with the abacus, but the rising and falling of the abacus contained the arithmetic skills of Cangming's sword; when the account book was opened, the pages turned into sharp blades to repel the powerful enemy. Armed with an iron ruler, an abacus, and an account book, the world's number one accountant, as a simple businessman, calculated all the sins in the world. Using his pen as a sword and accounts as an array, he walked a chivalrous path unique to the accountant in the world of swords and swords.
