Moving the map to his chest, Casio went straight to the third floor.
As the light shone, densely packed spider web-like black patterns crawled all over the space. The floor, the walls, and even the ceiling were covered with these ancient and exquisite tracks.
These patterns were not only on the third floor but had also penetrated into the walls, covering the entire Shelter Tower. All it needed was Casio's spirit blood as energy to turn it into a safe house.
Standing at the entrance to the stairs, Casio turned to glance at the path to the fourth floor. The upper part of the Shelter Tower had collapsed and been destroyed, and naturally, some of its original functions could not be used.
