Top financial auditor Su Yanqing transmigrated into a widowed wife of a state duke's mansion, holding bad accounts and a six-year-old stepson. Facing clan usurpation of titles and parasites embezzling relief funds, she decisively restructured assets and started a fabric business war. Originally intending only to save enough silver to shed its shell like a cicada, resign, and retire in seclusion, she unexpectedly found that the cold-faced powerful official Gu Hanchuan, rumored to have died in battle, was secretly steering the helm. The two joined forces amid layers of murderous intent to set up plots and make a comeback against the wind. When tens of thousands of liang of gold were credited, this calculation of resigning and running away was unexpectedly and entirely embraced along with the accounts by the current powerful official.
