Mr. Rabbit's Mansion
The overall scale of the building wasn't particularly large, only about 20% larger compared to William's theater or the sisters' Soft Hall.
However, the choice of materials for the building was quite particular.
It was neither any rare metal nor any special wood, but a special kind of physical matter called "Solid Frame Muscle" that had been modified. Its strength was even higher than many rare materials, and the fine muscle fibers could be clearly seen on the surface of the walls.
The most important thing was that this was not any ordinary dead muscle; each piece of muscle was alive.
Although William hadn't done much physical training recently, he still had his basic skills. Following the muscle's sensing, he directed his gaze upwards and quickly found the "Main Brain" controlling the building's muscle groups.
