On the eve of his expedition, General Xiao Chongyi handed over a deed of separation. Si Rou, a merchant's daughter, resolutely agreed, moved back all of her million-tael dowry, and sealed off food supplies by leveraging the northern military supply trade routes she controlled. In the imperial court and hall of justice, using ledger evidence, she tore open the conspiracies of the Xiao collateral branch and the Marquis of Dingyuan's Mansion, and investigated the old case of her mother being murdered. Having cleared her grievances and reclaimed old debts, Si Rou no longer trapped herself in romance, established a women's academy, took charge of her family's trade routes, and lived out the life uniquely belonging to herself.
