The Lightning Soil was an extremely precious type of spirit soil, and it was the best type of spirit soil for nurturing lightning-attribute spirit herbs and spirit medicines. It was just that the method to create such spirit soil had long been lost.
Appearance
It was a purplish-black sludge. Huge purple bubbles would pop up from time to time and explode. A purple gas was emitted, mixed with surging heat waves. There was a layer of faint purple mist floating above the swamp, and one could vaguely make out tiny arcs of electricity flickering within. The air was filled with a frightening aura. The blackish-purple sludge looked filthy, but it was rich in spiritual power and pulsed with the power of lightning, making it clear that it was no ordinary soil.
