He yelled, ‘I’ll get you all!’ and the very pale, almost invisible shimmer of the ionized air in the path of the whip’s energy beam made its appearance. It swept wide through the air, and the path of the beam intersected Biron’s foot. It was as though he had stepped into a bath of boiling lead. Or as if a granite block had toppled upon it. Or as if it had been crunched off by a shark. Actually, nothing had happened to it physically. It was only that the nerve endings that governed the sensation of pain had been universally and maximally stimulated. Boiling lead could have done no more.
