There were also cases of mislabeling, where a remedy meant for a common cold was touted as a cancer cure. This is a blatant case of misrepresentation, but the actual efficacy can't be denied. Such elixir recipes can only be discerned by analyzing each herb involved.
After a lengthy period of research, Ling Zhenfei finally ruled out the fake elixir recipes. Almost all the recipes collected by Si Mayang turned out to be useless, with only one left—the Nine Revolutions Soul Restoration Pill—which Ling Zhenfei judged to be genuine.
The Nine Revolutions Soul Restoration Pill was also a lost elixir, with an extremely complex production process, yet the effects were outstanding. As long as a person's life was not fated to end and their Essence Qi was not dissipated, they could be revived with this single pill.
Finding such an elixir recipe made Ling Zhenfei feel that his efforts were not in vain; the discovery could be considered immensely significant.
