The Female Physician in Zheng He's Fleet

Any Late Ming Dynasty Novels That Can Stand Beside Ke Shan Meng’s Iron-Blooded Remnants?

No System stories, and especially no brainless transmigration stories where the protagonist makes guns and cannons. In short, I want two things: realism!!! Starting from nothing and making progress step by step. It doesn’t have to be set in the late Ming, as long as it’s a time of chaos.
