Crafting talismans required not just talisman paper but also specialized talismanic ink and a talisman pen, yet Fang Yuxin had none of these. The talismanic ink needed to be refined from special materials, while the talisman pen was a type of Magical Treasure that required special crafting; she simply could not produce them now, so she could only use her True Yuan to draw.
Fortunately, as a Pure Wood Spirit Body, she had a high affinity with Vajra Wood, so even though it was her first time using it for crafting, she did not fail and succeeded immediately. Had it been any other material, directly using True Yuan to inscribe runes might have led to uncontrollably strong force, and consequently, the destruction of the material.
