Even Non-Humans Have to Pay Rent! [Unlimited]

On a graduation trip to a beautiful mountain villa, classmates were involved in a terrible incident. Bloody fingerprints in the toilet, classmates missing and dying one by one, the ghostly midnight... There are also all kinds of weird rules. [You are not allowed to use the toilet after 11pm. If you must go, please avoid the second stall. ] [Be polite, say thank you when you get food, and if you accidentally eat red bones, please quietly put them into someone else's bowl] [When someone calls your name while sleeping, don't answer...] The villa fell into panic and everyone was in danger until a few days later, a new guest came to the villa. She drove up in a shabby three-wheeler, wearing a simple tank top, shorts, and flip-flops. Everyone thought: Another one is rushing to die. However, after her appearance, a new rule suddenly appeared in the villa. Tenants must pay rent (regardless of whether they are human or non-human!!! * My name is Ling Yi, the billionaire's name. After my parents passed away, they left me a letter. The letter said that my family owned many properties all over the world. I almost fainted from the joy of suddenly becoming a rich woman. Doesn't that mean that as long as I collect the rent, I can pick my feet at home and lie down? The letter also said that the tenants were very disobedient, difficult, and cruel, and that I had to go door-to-door to ask for rent. No problem. After all, I am the landlord, the biggest landlord, and I will evict anyone who does not pay rent. But wait... All over the world? Also, why didn't you tell her that those tenants... Weren't human at all? ! But—— In my territory, you have to obey my rules, even non-human beings have to pay the rent. No one or ghost can stop me from becoming a billionaire. * Tentative copy: "Isolated country house" "Amusement park closed down due to frequent hauntings" "..."
