Experts usually store their techniques in inscription patterns. Writing them onto inscription scrolls, then when in battle, they can activate the inscription scroll to release powerful battle techniques, much faster than if they were to perform the techniques themselves. But inscription scrolls are usually very expensive. Just a blank inscription scroll would cost up to hundreds of demon spirit coins, a bronze rank inscription scroll would cost thousands of demon spirit coins, and a silver rank inscription scroll would cost more than 10 thousand demon spirit coins. As for gold rank, the price of it is simply unimaginable. They are extremely precious things which ordinary people can not afford.
