I Became a Breeding Ground Slave, and Rule the Beast World by Having Cubs

Transmigrated into the lowest-ranked birth mother on Beast Star, Tu Nan is locked in an iron cage, numbered, appraised, and sold off for next to nothing. She is destined to give birth again and again until her life is spent.

Everyone says that with her constitution, she will be ruined before her third pregnancy, not even fit to serve as a breeding tool.

At the moment of crisis, the System awakens.

She throws herself into the arms of a powerful male beast with a disfigured face, tears streaming down as she begs him to buy her.

She succeeds. From then on... she chooses the strongest mates, bears the fiercest cubs, and completes her own genetic makeup.

Her first litter awakens the White Tiger bloodline, her second gives birth to a phoenix reborn from the ashes, and her third inherits the top royal bloodline, returning to its ancestral roots. Every one of her children is extraordinary, and they all acknowledge their mother, not their father.

The nobles want to claim kinship? Cut them off. The general wants to take her? Kill him.

The emperor bows his head and begs her to bear another child, but she turns to ask her children, "Do you want a little brother or sister? Is there enough of this world left to go around?"
