Tangmo and the others weren't using magic crystal powder, but magic circuit cables produced by the Otherworld Research Center, a product combining Earth technology with Otherworld magic, primarily used to guide magical power and achieve some of Earth's common physical functions.
The ultra-mobility devices worn by the Advance Team and the sights on their weapons utilized these magic circuit cables. These were magical cables made by combining magic crystal powder with several types of metals known for their flexibility.
The emergence of magic circuit cables mainly addressed some objective magical challenges, such as if one wanted to draw a rune, one had either to carve it or use magic crystal powder to draw it, both of which had certain limitations. Therefore, magic circuit cables were primarily advanced substitutes to replace both methods, bringing Otherworld magic directly into the industrial civilization level.
