As soon as Qin Yao opened her eyes, she was transported into the body of an ancient peasant woman from the end of the world.

There are four stepsons at home waiting to be fed.

A bastard who has nothing but good looks is jumping up and down.

The family lives in a thatched hut with not even a grain of rice in the jar. The whole family is as skinny as refugees.

Forget it, there are still people coming to ask for debts!

Qin Yao was angry from the bottom of her heart and kicked her bastard husband out, “Brother who wants to pay debts, please just beat him to death!”

Four stepsons:! ! !

The world is clean, Qin Yao rolls up her sleeves and makes a fortune.

She is great at hunting, carrying bags, and killing horse thieves.

It is this kind of land, facing the loess and turning its back to the sky. Even the top strong men who have been struggling in the apocalypse wave their hands repeatedly: I can’t stand it! I really can’t stand it!

Qin Yao scratched his head: In ancient times when agricultural taxes were extremely high, how could we stop farming?

At this time, the lazy husband who was sent to die (twisted and crawled) (struggled to stand up) (screamed and roared): Wife! I think I can still save a little more!
