After transmigrating to the Tang Dynasty, Chu Qiao faces a crisis greater than political intrigue or battlefield slaughter: the bachelor tax. The court decrees that anyone over sixteen who isn't married must pay up. Those who can't afford it will be conscripted into the army. Big Niu from the village keeps cornering him to set him up with someone, and has even lined up a thirteen-year-old girl. Chu Qiao goes along with the matchmaking while observing this strange world, where something always feels off. Then one day, some street thugs snatch a woman in broad daylight, and a scholar steps forward to stop them. At last, Chu Qiao is certain: there's definitely something wrong with this Tang Dynasty.
