After Becoming an NPC, I Started Causing Trouble in the Infinite World [Infinite]

After Fang Yunhan died, she transmigrated into a world of ghosts and monsters and got a System. [You have entered an infinite world of ghosts and monsters and become an NPC within it.] [There is a ghost in the bathroom to your left, one of your tenants on the right is not human, and a monster is hiding inside the voice-activated light ahead...] [You feel terrified.] [You are the landlord of this building, but too many things are happening here for you to handle.] [So you are about to bring in countless players.] [You are about to sell this building and wash your hands of it, beep, beep, beep, ] The System's voice got stuck in its throat. Before it could get another word out, the newly recruited NPC spoke in a voice like a death warrant: "I have a question. If I'm a ghost, why am I scared? Also, this building belongs to me now, right?" A fifty-story skyscraper, luxuriously finished, with entrances leading into an infinite world. Players everywhere you looked. If she managed things well, Fang Yunhan reckoned she could get at least eight thousand in rent per apartment. As for how many ghosts there were... Were those ghosts? Huh? Weren't they the round-the-clock odd-job workers and part-time security guards in my building? We're all ghosts. Why would I be afraid of them? :) The world warped. Infinite ghosts and monsters invaded, and supernatural phenomena appeared one after another. Everyone would enter an infinite world to be put to the test. The most extreme case was a fifty-story skyscraper that had inexplicably appeared downtown, spreading an ominous aura across the entire city. Danger Level: SSS The government sent its strongest player, Wen Zheyi, to clear it. Wen Zheyi entered the building and met the ghost NPC landlord. After taking a huge sum of money from him, the landlord declared love at first sight and hinted that she needed a pretty boy to help her save face. Faced with the invitation from the evil ghost landlord, Wen Zheyi: ... The System's binding to Fang Yunhan had been an accident. Seeing how obsessed she was with making money, it initially thought she wouldn't survive even one world. But who could have guessed? System: She's vicious, violent, and completely unhinged. She's greedy, but no matter what she goes through, she still has the most basic human heart, and loves doing the things humans enjoy. System: Like staging a rebellion. System: Or keeping a pretty boy. System: The boss is amazing! Reading Guide: 1. The rebellion unfolds gradually. 2. The protagonist is a ghost, a ghost with very few scruples. She will regain her sanity later on. 3. This isn't a puzzle-solving story. It's my take on the infinite genre. 4. Updated daily at nine. Theme: With enough determination, you can overcome anything.
