With Yang Jing's current mastery of Artifact Refining, a single glance at the diagrams was enough for him to identify which Spiritual Materials needed for the Flying Boat could be swapped for lower-grade substitutes. While still incredibly rare, these substitutes could at least be found.
'This Ten Thousand Years Divine Wood... there's no substitute for it.'
Yang Jing frowned and set down the Jade Scroll.
The Flying Ship True Spirit required a piece of Ten Thousand Years Divine Wood at least nine zhang long to serve as its Dragon Bone. This Dragon Bone had to bear the brunt of the power from the Flying Boat's Arrays and also support the Restriction formed from the True Spirit's True Blood. If the material were even slightly inferior, the Flying Boat would destroy itself during operation.
Ten Thousand Years Spirit Wood was common enough—the Five Elements True Spirit Sect had plenty within its grounds—but not a single specimen qualified as Divine Wood.
