The difficulty of trying to evolve a high-grade spiritual vein into a lesser dragon vein was comparable to creating a top-tier blue-grade art from scratch, or scaling a forty-thousand-meter mountain on broken legs with nothing but your hands to work with.
Outside of the difficulty, the resources required were just as daunting. From what Yang Qing had read, it would need at least three or four middle-tier ascendant-grade treasures just to transform a high-grade spirit vein into a lesser dragon vein, and even then, there were still other considerations, such as the specialized knowledge and level of skill required to make such a thing possible.
