Don't Panic: After My Whole Family Transmigrated, I Farmed with a System

When she wakes up, her whole family has transmigrated together into ancient times as a doomed farming household: her father is a gambler, her mother is chronically ill, her younger brother is a future villain, and she, Lin Manman, is the unlucky eldest daughter about to be sold off as a sacrificial bride.

Faced with a hellish start, Lin Manman smiles calmly. "It's no big deal."

Bound to the Ancient-Era Guide to Getting Rich System, she receives a sack of high-yield potatoes from the start. Her gambler father stares at them, eyes shining. "Sweetheart, can these things be used to make vodka?" Her sickly mother pulls out a silver needle. "Actually, in my previous life, I was a renowned doctor." Her future-villain brother takes out a homemade crossbow. "Sis, whose landlord are we robbing? I'll scout ahead."

The whole family gradually goes off the rails.

While the villagers wait to laugh at them, the Lin family's potatoes yield a thousand jin per mu, their liquor becomes famous across the land, and their clinics spread throughout the prefectures.

Then one day, the handsome amnesiac scholar they had found by the river quietly takes out a dragon-patterned jade pendant he had kept hidden.

Looking at the black-armored cavalry surrounding her fields, Lin Manman falls into thought. "...Is there still time to take up farming?"
