Starting from the Talisman of Peace, It Comes to the World

There are nine levels of talismans, and each level has nine talismans. The level of quality does not depend on the number of strokes. A first-grade peace talisman can be drawn in seven strokes. But if you want to draw the ninth talisman of the first grade, you need ninety-nine strokes. A third-level attack talisman can be drawn in eighteen strokes. But the power of the eighteen-stroke talisman is a hundred times that of the first-grade nine talisman. The grade is the qualitative change of the talisman's power, and the strokes are the shape of the talisman's pattern. Some talismans have more strokes, and some have fewer strokes. But no matter how many strokes there are, the last stroke is always straight.
