The Dragon Son-in-Law of Great Qin

Su Xiu transmigrates to the Great Qin dynasty and discovers that the government requires everyone to get married. Those who refuse face a fine at best and prison at worst.

Not married? No problem. The government will assign you a wife.

Then, after offending a local official, Su Xiu is assigned a widow nobody wants.

And that widow's name is Ba Qing.
