From the Start, Exiled, I Solve Cases to Gamble with My Life

Qin Mu transmigrates into the illegitimate son of a marquis's household, and is due to be exiled in three days.

He plans to turn his fortunes around by solving cases, but his stepmother forces him to marry a divorced woman with a scandalous reputation.

The whole capital is waiting to see him stuck with her, but Qin Mu turns around and sends the woman to his father's bed.

“Since Father likes her, your son will gladly make this ‘match made in heaven’ happen.”
