Most of the last bolt had scattered in the wind. Enough had come down through his arm and into his dantian to set the Foundation.

He drew cold water qi into the basin until the temperature fell from three hundred degrees to seventy-two point four. Then he gathered yellow earth qi at the very center. A single tiny cube formed with a clear ping. From that seed, crystal grew outward in even rings.
