[Female-led political intrigue, dimensional superiority, satisfying revenge, some romance but not much, and a slightly deranged, secretly ruthless heroine]
In the Xu family of the capital, a seventh-rank official's household, there is a sixth young lady who barely registers.
Her mother died young, and her father is a simple, honest man.
Everyone thinks that this motherless girl will eventually be married off to just anyone.
But no one expects that the seemingly frail sixth young lady is ruthless beneath the surface.
When her cousin is harassed by a scoundrel, she throws him into a pond, then sends his entire family to prison for good measure.
She opens a rouge shop and gathers followers. Anyone who schemes against the Xu family is dealt with until they know their place.
The current dynasty's Grand Princess says, "This girl is interesting. I need a strategist. Come work for me."
Prince Ning rebels, his army at the city gates, and the officials in court are so frightened they're wailing for their mothers and fathers.
Xu Qingci calmly pulls out a repeating crossbow and brings out her "Divine Machine Battalion" as well.
"Sorry, but in this age, chemistry and physics are called dimensional superiority."
Later, everyone in the realm knows that the Dayan Dynasty has produced a remarkable woman with immense influence and a plan for every contingency.
Prince Ning is driven into a corner, Prince Su is ruined, and the Grand Princess ascends the throne as emperor, while she
becomes the first female chancellor in Dayan history, with power over the entire court.
