The biggest difference between the modern pharmacology introduced by Zheng Fa and the traditional Xuanwei Alchemy is the emphasis on experimental standards.
Take the Supreme Pill Dao, for example—this is a subject so vast and profound that it's beyond measure. After several eras of development, the Supreme Dao has accumulated terrifying experience.
This is also why the Jiushan Sect's Alchemy, after years of development, still lags significantly behind the Supreme Pill Dao—
Alchemy is a highly experimental field, essentially a discipline guided by experimental theory.
Some pills, or even a large number of pills, are often born of coincidences. Before their creation, there was no corresponding pharmacology.
After a pill is completed, a Great Power will naturally engage in its thorough analysis.
Such coincidences are essentially one or two unexpected successes after numerous ineffective attempts.
