After Get Off Work, I Picked up the Big Devil

"My name is Li Nansheng. I have an older sister, a childhood sweetheart, and a pair of twin sisters next door. However, they don't like me. My biggest dream is for all cats in the world to become extinct." "I usually work part-time as a D-class spiritualist, barely meeting the KPI of "protecting world peace." But one day a big devil who calls herself my mother comes to me. She says she wants to destroy the earth. I am the spy he sent, and it's time to lead the way."
