Weird World: I Just Want to Build a Safe House

My name is Lin Yuan, an ordinary architectural designer. When I woke up, I was pulled into the world of ghost stories. The system pops up rules: Do not go out, do not look in the mirror, and do not respond to knocks after 12 midnight. Others were trembling, and I looked at the cracks in the wall—— This wall is made of hollow bricks and cannot bear load. Something disguised as my mother was crying outside the door. I covered my mouth and made no sound. It scratched outside the door all night while I studied the floor plans in the house. The next day, I discovered that the stairwell circulated, and no matter how I walked, I was still on the third floor. Others panicked, but I laughed—— Going up does not necessarily mean going up, and going down does not necessarily mean going down. I opened the window and jumped out. Ground floor. System prompt: Crack the hidden rules, +200 points. Now, I have 350 points. You can replace it with a bag of cement to strengthen the door that is almost broken. You can also replace a packet of seeds and grow some vegetables on the windowsill. Others are trying to survive, I am trying to survive. The survivors in the ghost story world call me "crazy". Until my safe house turned into a fortress and they started calling me— "Master Lin". I just want to build a safe house. How come you have become everyone's hope by continuing to practice?
