Baby Xie Ningxing took the note left by her mother and came to the Xie family, finally finding her father, Xie Chengyuan. Just as she was adapting to her new life, the good-luck system Zero-Zero-One in her mind told her that her family would encounter difficulties one after another. Xingxing could not understand the complex tasks, but she could always bring a turning point in her own way at critical moments to accompany her uncle, get closer to her grandfather, and also help her father look for her mother. This little girl made a family whose members each had their own concerns learn to understand each other and guard one another.
