After I Transmigrated into a Book, I Became the Wicked Stepmother of Three Kids

Yan Nanxu, a power-type esper in the apocalypse, blew herself up while fighting the Zombie King, killing them both. After her death, she transmigrated into the body of a person with the same name in another world.

To her utter shock, her predecessor already had three children. Her husband had left after the court's conscription order and was said to be dead. Her mother-in-law had stolen their compensation money and driven them out. Since she was here, she decided to make the best of it. Yan Nanxu planned to be a good stepmother, raise the children, build a fortune, and reach the pinnacle of life.
