Qu Zhigao thanked Zhang Xiaohua and gave him the pill formulas he couldn't understand. Among them were several formulas, with the "Bone Condensing Pill" recorded at the very front. The herbs used in these formulas would have been difficult for Zhang Xiaohua to find even if he were in Huichun Valley. But now, he was in the Xiang Sect, specifically in the Expanding Elixir Hall, a place where the Immortal Inheritance Great Teachings specifically cultivated medicinal herbs. Although other cultivation techniques may have vanished, the herbs for refining pills have always been available.
Perhaps the medicinal uses of some herbs are obscure or even the formulas could have been lost, but it's undeniable that many ancient herbs have been collected by different disciples, even if they may not know the names of these herbs! Perhaps it is only Zhang Xiaohua's "foolish" behavior of exchanging medicine for herbs that allows them to laugh secretly while throwing out unnamed and worthless herbs.
