Lin Qianmo is a well-behaved girl from the mountains. She learns from her elders at home and often listens to her tutor sing opera. She always dreams of becoming some kind of official, sure she'll be as impressive as the heroes in the plays.
Then her luck turns. She gets out of the mountains, and with even better luck, takes over a shop as soon as she arrives. But when her luck runs out, she discovers the shop is a million silver taels in debt.
To pay it off, she clears land and grows medicinal herbs, then opens a shop and treats patients. But she can't even afford the taxes on her herb fields, and rules are everywhere. So she decides to take the imperial examinations to get a tax exemption. Once she starts, there's no stopping her: she makes it to the Grand Secretariat and becomes Chief Grand Secretary. At last, her chance has come to establish rules of her own and prevent trouble for good.
Wait, why does the First Imperial Merchant keep trying to cozy up to her? He's just like someone she once lost. And wait, why does the kid sitting on the dragon throne look exactly like the new underling she just took in? And one more thing: why did the money she repaid end up in her father's hands? Something's not right. None of this is right!
