Lu Ren picked up an ordinary brush and then some clear water, beginning to practice on the white paper.

This was the simplest and most direct method to practice talisman crafting: using clear water to sketch runes, completing the drawing before the water fully soaked into the paper.

However, runes were extremely complex, and each rune pattern had to be completed in a short time, or all previous efforts would be wasted.

Generally, for someone to become a first-level talisman master, it would take five to ten years of arduous training to even get started.
