I Became the Ninth Princess, and Won Over Handsome Men by Building City Walls

[Strong Female Lead | Political Intrigue | Transmigrate and Keep the Books | Everyone Is Career-Minded]

A road and bridge engineer dies when a plateau tunnel collapses. When she opens her eyes, she has become Yan Zhiwei, the least favored of the nine imperial princesses in the empress's Yaoguo Dynasty.

The empress sends her to guard Yanhuicheng, a city that has collapsed twice in three years and cost two thousand lives.

She knows nothing of political intrigue or swordplay. All she knows is how to calculate earthworks, mix lime mortar, and build drainage systems.

She turns a ruined city into an impregnable fortress, and carves out a path of her own along the way.

On the day she ascends the throne, she grants none of the four men a consort's title. She says just two words: “One ledger.”

And with that, she brings the four men who should never have belonged to her into her own city.
