A lucky wife born again from a farm family

A female military doctor was reborn in ancient times and ran away from a drought. Her grandfather was a scumbag and her grandmother was a poisonous woman. They wanted to sell her whole family for food.
Gu Jinli said: It’s not a big deal, let’s get rid of Mr. Zha’s evil mother first, then find water for food, and lead the whole family through the famine.
I fled the famine and settled down in Dafeng Village. It was difficult for outsiders to mix and they were oppressed in various ways. How to overcome it?
Gu Jinan said: It doesn't matter, brother, I am a big shot in the imperial examination.
Life was going on in a pleasant way, but there were wars and disasters everywhere. Gu Jinli flipped the table. This girl just wants to farm and fight. Get out!
The little brother I picked up while running away from famine: Madam, don’t panic, your husband-in-law is a madman on the battlefield. He rebelled against the marquis and protected you from thousands of acres of medicine fields, and you will be safe for the rest of your life.
PS: A story about slapping people in the face and torturing a scumbag, the male and female protagonists are clean physically and mentally, they love each other 1V1, and the ending is happy. [The heroine does not practice medicine, but only uses medical knowledge to make a fortune^0^]
