Song Lei had been living his life in poverty and taking care of his younger sister until that day. After losing his life at the hands of his drug-addict father, Song Lei was transmigrated into the city of horrors. In the city of horrors where an uncountable amount of monsters and ghosts reside; Song Lei has to use his wits to survive and find a way to go back to his sister... "Are those authentic ghost repelling talismans on the wall?" "Yes. Yes, they are." "So? Why is there a ghost standing right next to it? Do you think he is being repelled?" "Nope. Not even a little bit. Oh look, he's coming toward us." "Well, that can't be good..."
"We have to talk about yesterday," the teacher started saying. "As you know, there has been an unprecedented increase in the amount of invasions we have been experiencing these last few months. Experiencing an invasion every week was already very taxing on our human resources. We can't afford to lose any more manpower than we already have. However, yesterday was an absolute disaster. And it probably is a precursor for much worse things to come."
Hearing the grim words of their teacher, the always rowdy and crazy students became more tame. No matter how many problems they had in their heads, the current situation was too harsh to ignore.
