Folklore: Evil Spirits Are My Infrastructure Materials

When Jiang Yu crossed over, he was lying on the morgue. Outside the door is an eyeless infant spirit squatting in the crack of the door, specializing in gouging out people's eyes. Three days later is the lunar day, when all the evil spirits from the back mountains and mass graves will come out and knock on the door from door to door. He only has an eight-year-old sister beside him, and a child bride who was chosen by his parents before his death and is so thin that there is only a handful of bones left. Just when everyone was waiting for dawn to carry him to the back mountain and bury him, he awakened the "Folk Cave" system. This system has no tasks, no rewards, no forced guidance, and not even a single superfluous word. It's just a cold toolbox. Give it peach wood, and it will build your town house wall. Give it stove ashes, and it will pave the way for you to exorcise evil spirits. Give it a complete evil body, and it will build a gatehouse that can automatically slay demons. Then, the people of Black Rock Village discovered something strange. Others were haunted by evil spirits, hiding under the bed and shivering, holding a bald mahogany sword in their hand. Jiang Yu encountered evil spirits and went out with an ax: he happened to be short of materials to build a fence. Others close their doors and windows on cloudy days and pray to the mountain gods for protection. Jiang Yu was cooking in the yard, waiting for Xie Sui to come to deliver building materials. I didn't want to be a savior. I just want to have a peaceful sleep without nightmares. But later on, my house got bigger and bigger, from a leaky adobe house to a city that could accommodate 100,000 people. Later, people in the entire lower world were looking forward to me building a house in front of their house.
