Most of these materials were made of wood. Their physical uniformity was somewhere between skeletal materials and metals. They were better than skeletons, but not as uniformly dense as metals. This meant that the production of larger wooden structures can be automated, and Ye Chong need only tweak the smaller details later. The modern technology embodied in the photon processor provided a great convenience in this process. Ye Chong can design the structure on the photon processor, and the intelligent machines would process the raw materials according to the design's requirements. This saved him a lot of work.
