"The reason why I copy homework so fast is that I fight monsters every night." - Lin Xinyi's daily life. On the surface, he is a scumbag, but in fact he is the "night cleaner" of the town. He used his spiritual power to eliminate monsters every night. This kind of life lasted for three years, until the time-stop barrier suddenly came during the big class break, an organization calling itself "Guardian" appeared, and monsters turned into buses attacked on the way to school... Only then did Lin Xinyi discover that he was not the only "abnormality." "Why can my spiritual power materialize without spiritual martial arts?" "Why are the monsters getting stronger and stronger recently?" "Why is the world getting weirder and weirder?" When the rooftop of the campus turns into a battlefield, and when the familiar streets are filled with crises, this scumbag girl who just wants to survive until graduation has to face the fact: the ordinary daily life she cherishes has been an illusion from the beginning. "In this case -" the ice blue spiritual power condensed in the girl's hands, "then use my way to get the 'ordinary' back!"
