The principles behind the Spatial Ray Blade and the Spatial Barrier are similar—they both condense spatial rays to achieve defense or attack effects. The main difference is that it's harder to create a blade; it requires knotting spatial rays together. Up till now, Xu Huo could only make simple ray blades. The coverage was considerable, but relatively thin, so Defense Props and Protective Suits could block them.
Reinforcement is actually the process of knotting spatial rays multiple times, like instantly pulling up a spatial ray barrier. It not only requires skillful manipulation of spatial rays, but must also be accomplished quickly.
Xu Huo had seen spatial ray blades that could pierce Rank-A Space Defense Props when he fought Mr. Kang in a high-risk instance. The way those rays knotted together was like spatial power freezing and exploding into countless ice shards. Not only could they shatter prop barriers, but with enough coverage, could even destroy cities.
