Since most sword cultivators who needed a growth-type sword embryo were not compatible with this particular embryo's attributes, and the cultivators who were compatible had little demand for spiritual swords, Jiang Yuejing eventually won the bid for thirty-seven thousand low-grade spirit stones.
Along with the sword embryo, a piece of black wood was brought into the private box. "What is this?" Jiang Yuejing asked, pointing at the wood.
Yun Shuo stepped forward to touch it, then explained: "This is wood from Gale Valley. Gale Valley is battered by hurricanes year-round, and lightning strikes are common, so the trees there have extremely tough timber. This is probably meant for making a scabbard."
