Shen Ning transmigrates into a novel, becoming a D-rank cannon-fodder character who was abandoned on a desolate planet by a scammer and wouldn't survive even one episode. She can't even measure up to the most basic abilities, occupying the very bottom blank space on the rating chart. And the three children she must raise are: Tian Luo, a little puppy who wags his tail; Yi Yun, a little mermaid who gives away his scales as gifts; and Ai Huihui, a pureblood baby whose rank cannot even be measured.
