Li Mumu didn't disdain the short-haired girl for being a dead person.
After all, everyone here is a demon or an evil spirit; who's there to look down upon who when you're all living in such a place?
Moreover, the girl had indeed kindly given her a warning just now, and all Li Mumu felt was gratefulness.
She gently knocked on the iron door, but there was no response from inside.
So, Li Mumu gradually increased the force of her knocking.
Clang! Clang clang——!
Suddenly, the iron door burst open, and a chain shot out from inside, hooking around her neck and yanking her in.
Li Mumu's forehead slammed into the coffin, causing her tears to fall from the pain.
The lid of the coffin cracked open slightly, the chain swiftly retracted back into it, revealing half of the short-haired girl's pale, lifeless face.
"What is it?"
Li Mumu said with a dry chuckle, "I've just been thrown in here and I'm unaware of the rules. I hope you can give me some advice, sister."
