An accountant discovered that a foreign bank had false accounts. Starting with a missing three thousand taels of silver, he discovered a chain of corruption from the foreign bank to the customs to the Ministry of Industry. He did not fight in the war, did not hold an official position, did not rely on connections, but relied on checking accounts and abacus to turn his life around. Then he started from the dock, moved step by step from the accounting room to the arsenal, and finally stood in the position of changing the destiny of the country.
