Xu Huo's previous control over spatial rays had always been fairly superficial. For example, the ray barriers he created rarely formed closed shapes—in most cases, he just increased the barrier's coverage area to approximate the effect. The Ray Blade worked similarly.
Lady Palace could create a fully enclosed spatial container, layering it again and again until it was compressed enough to resemble a bomb.
After mastering ray control, he could make similar cubes—not just cubes; with some effort, he could even craft irregular spheres, though cubes were simpler. Without relying on "Cubic Space", he could stack about ten layers. Within the "Cubic Space" range, that number could double. However, the spatial rays in the instrument's range weren't evenly distributed, so operating them took extra caution.
