Lin Mo is an upright and positive young man. By day, he receives a socialist education at school. At night, he quietly studies all kinds of occult techniques at home, all because his childhood friend Li Zhou is constantly in need of saving.
Li Zhou has been good at everything since childhood: he's handsome, gets good grades, and comes from a well-off family. There's just one problem: something is always trying to harm him.
Lin Mo kept watch day and night, but someone still found a way in and possessed his childhood friend. He doesn't currently have the power to get his friend back, so all he can do is let him act as a guardian spirit for a while.
But now that his childhood friend is a guardian spirit, why does it seem like ghosts aren't as interested in him as they used to be?
