He is the first of the clones to become a Sovereign of law so he is the first to enjoy the benefits of the complete body of law. His body made it as if he could move the world just by willing it. It is not so but he still decided to relish that unique feeling of being at the top of the world.
He sighed in pleasure. "The power of the world is at my fingertips."
The body of law is a physique gained at the titan of law stage. It is a result of the waste of essence during the breakthrough to a titan of law and during the duration that the entity is a titan of law.
The body of law is both a good thing and a bad thing. It is a bad thing because it is created from the essence of an entity that is lost during the process of becoming a titan of law.
