The Cannon Fodder Old Lady's Road to a Comeback

She was a botanist with a bright future, but overnight she transmigrated into the body of an elderly woman in ancient times: someone else’s ancestor, a difficult old woman, and a cannon-fodder character.

But now she was here. She led the whole family in making money and building houses, opened a factory, improved the rice seeds, raised the younger generations, and even led the whole village to escape the ravages of war...

How was she an ancestor? She was busier than any of her grandchildren.
