Horror Returns, and I Won't Spare Even a Ghost

The crimson moon appears, terror returns, and demons and monsters run rampant.

Su Ye, dumped by his girlfriend, obtains the Netherworld System. The more ghosts he kills, the stronger he becomes.

Hanging Ghost: “Oh no, this guy doesn't even spare ghosts! I strongly demand a law to protect us!”

Door-Knocking Ghost: “Boohoo, all I did was knock on the door, and he tied me up and forced me to learn a trade.”

Alliance of Ten Thousand Ghosts: “Humans might put up with this, but ghosts won't! Let's pool ten billion underworld coins and buy Su Ye's life! Remember, we mean his life, not his dog's!”
