Living in the 21st century, the heroine, Xiaotu, a seventeen-year-old high school student who grew up believing in science, woke up one day and found that she had become a soul body, a legendary "ghost" that does not exist in the mortal world.
She didn't know where she should go at this moment, so she could only stay in the world and stay with her family all day long.
No one saw her, and she didn't find any other... Well, ghosts like her.
She only vaguely remembered that she jumped from the building and died, but she could not remember why she jumped from the building. From her perspective, it was impossible for her to commit suicide out of mind. This became a question that troubled Xiaotu day and night.
One day, by chance, Xiao Tu was guided by a Mr. Yin Yang and found an ancient building. On the huge plaque of the ancient building, three powerful characters - City God Temple - were vaguely visible.
