Terror Times: I Became a Refuge

In the outside world, hundreds of ghosts walk at night, curses fill the sky, demons are rampant, and people in the city die at every turn. Xu Que traveled through time and came to this world. But instead of being reborn as a human being, it becomes a refuge, a building. Xu Que, who had obtained the infinite upgrade system, decided to endure to the end. Train excellent spellcasters, let them work for you, go out to plunder resources, kill ghosts and monsters to upgrade yourself. "You upgraded the psychic cannon and killed a ghost king with one cannon." "You upgraded the city wall, activated the sky-reaching runes, and turned hundreds of ghosts into ashes at night." "You have taken in a beautiful woman, please don't have any unreasonable thoughts. You are talking nonsense." Xu Que: "I will never move a step unless it is upgraded to the same size as the earth!" So far, in this world where demons and monsters are rampant, there is a real holy place. This novel and its characters are purely fictitious.
