One hundred and seventy-some years since the founding of the Dasheng Dynasty, the national treasury unexpectedly has only seven hundred and twenty thousand taels left! The northern border army is waiting for their pay, the Jiangnan disaster victims are waiting for rescue, yet the civil and military officials of the imperial court dare not speak up. In a fit of anger, the Emperor summons a master of accounting, the rank-six junior official Lu Chenzhou, giving him ninety days to recover five million taels. Little did anyone expect that this inconspicuous rank-six junior official would truly dare to reach out his hand toward the powerful and noble officials of the entire court. And as case after case of corruption floats to the surface, Lu Chenzhou gradually discovers that the problem of the Dasheng Dynasty is perhaps not as simple as just lacking money.
