Vale left the Night Society headquarters with a sense of satisfaction. Overall, he was satisfied with the outcome. Although he still had to prove the authenticity of the spirit plant cultivation method to get the Night Society's approval, their upfront payment of 8 gray-quality magic radiation stones had alleviated his initial anger, so he was moderately satisfied.
Although 8 magic radiation stones was a substantial amount, it was still short of his goal, which was approximately 1 blue-quality magic radiation stone. Theoretically, 1 black-quality magic radiation stone was equivalent to 10 gray-quality stones, but in practice, no one would trade 1 black-quality magic radiation stone for 10 gray-quality stones. It took about 12 to 14 gray-quality magic radiation stones to obtain 1 black-quality stone. Moreover, the difference in quality was glaring, with black-quality magic radiation stones far outnumbering their gray-quality counterparts despite the 10:1 ratio.
