There are actually many weapon design proposals, and Gu Tao temporarily divided them into two parts. One part belongs to custom-grade equipment, which is complicated in terms of craftsmanship, high in technological content, and can only be equipped in small batches. For instance, Mrs. He's sword, Axiu's nano-sensing tools, Liuchun's self-charging release devices, and so on. These items are difficult to replicate; even if someone stole the design drawings, with the current level of technology, it would be absolutely impossible to manufacture them.
The other part belongs to mass-produced equipment. Mass-produced equipment is for the majority of ordinary people who do not have a good control over power. Too advanced equipment could easily lead to their deaths, not to mention that they also lack the ability to manage such equipment.
