After reaching max level in the quick transmigration worlds, Su Ya exchanges her rewards for a trading space and returns to her original world.
It's a world inside a book, and her family are either cannon fodder or villains.
The first thing she does after returning is keep her three children away from the book's protagonists and spare them their cruel fate.
Then she leads refugees fleeing famine in building houses and founding a village, turning it into the wealthiest village for miles around.
Life just keeps getting better, until a man suddenly appears and says he wants to be the children's father?
A man would only slow down Su Ya's moneymaking, so she turns him down without hesitation.
But it turns out he's the children's biological father. What kind of crazy coincidence is that?
