Michael also experimented a lot with the blueprints procured from the Regional War. He hadn't used or sold them until now because it was obvious that he would need them at some point. However, using more than 2.8 million blueprints in experiments was easier said than done.
Michael didn't know how many days he spent using Insert and Extraction to combine fragments and extract certain components of a blueprint in an attempt to create rare, high-quality blueprints. He managed to create Specialized Training Range blueprints, an upgraded version of an Advanced Infirmary, Superior Ranches, Treehouse Apartment Complexes, and the like.
