Weird World, One Survival Point Every Day

[Farming, infrastructure, survival, evolution, integration] This is an extremely strange world. Whenever night falls, skeleton-like monsters appear outside. They knock on residents' houses. You can't make any noise to alert them, let alone respond, otherwise they will rush in and eat you. Here, every resident will place a shining stone at the door to resist the intrusion of skeletons. Until one day, the skeleton suddenly evolved, and humans could no longer resist it. Fortunately, Li Mi has a system. Not only can you strengthen yourself, but you can also strengthen items.
