Reborn in an imaginary financial family of the Republic of China a hundred years ago, the heroine uses the financial memory and quantitative thinking accumulated in her previous life to launch a war of revenge without gunpowder in an era when "foreign compradors" and "local banks" grew wildly. Instead of killing people with guns, she used silver dollars as capital weapons. Through modern financial methods such as futures, lending, and short-selling, she gradually disintegrated the enemy's family from within, forcing them to eventually sell their ancestral homes and become street beggars. But when she was about to complete the last step of settling the debt, she unexpectedly discovered that the real enemy who pushed her into the pit of fire in her previous life was actually someone she had always regarded as an ally.
