After Becoming a Haunted House Cleaner, I Bound a Vengeful Ghost System

Thirty thousand a day! To save my seriously ill mother, I take a job cleaning haunted houses. Who could have guessed that on my very first night, I'd find a bloodstained ring and successfully bind the Evil Ghost System! I have 72 hours to survive, or I'll become the ghost of this house!

A red-clad female ghost grabs me by the throat, demanding to find her child. A skeleton in the basement suddenly opens its eyes and speaks, while a man in black robes chases me, trying to steal my System! Luckily, the System grants me night vision and exorcism talismans, and even lets me turn evil ghosts into henchmen!

But every time I use an ability, it burns through my lifespan! Even worse, I discover that the hauntings in every haunted house are part of a secret organization's plot. They want to use resentment to resurrect an ancient demon, and my System is the key to opening the gates of hell!

Host, will you destroy the System or take control of its power? Your choice will decide the fate of humanity!

At midnight tonight, the door of yet another haunted house will open...
