Almost every sub-industry can make French seals and runes. It can be understood that, for example, weapons production can definitely be made into French seals. There are also hunters. It seems that jewelry can also be used. These are all related to weapons. If it's a tailor and nail-making, it's a rune. Almost all of them can be produced by ultra-clean printing. We need corresponding materials to explore new formulas, such as a glacier magnet and crystal, so that we can explore a new French printing formula. There are also some French-Indian formulas that need to be typed in special places. For example, there are few celestial runes in the national costume (there is basically no difference between French and Indian runes), so it is not easy to use by hand. If you don't understand, you can trust me privately.
