"A Sixth Rank Spiritual Root..."
Although there had been preparations for a "stab in the back," the move by the Peony Fairy still went beyond the expectations of the Cloth Sack Arhat and the Pagoda-carrying Arhat.
A Sixth Rank Spiritual Root, though only of the sixth tier, was invaluable. Even True Person Ziyang's Golden Jade Coiled Dragon Ganoderma couldn't compare, and the Flood Dragon Inner Pill offered by Pure Jun Sword Lord and the Great Roc King was far inferior.
Because it was a Spiritual Root, not a mere Spiritual Object.
The difference between a Spiritual Object and a Spiritual Root was like that between an egg and a hen. If the egg doesn't hatch, it's a one-time consumable, gone once used.
But as long as the hen doesn't die, it can continue producing endlessly. Thus, its value is indubitable, even if Golden Jade Coiled Dragon Ganoderma, a Seventh-Rank exquisite Spiritual Object, falls short by comparison.
