The Alchemy Sect is most adept at refining spirit medicine, followed by the Observing Body Sect, and the Spring Rain Pill is the spirit medicine of the Observing Body Sect, but it's quite unpopular.
It's primarily meant for ordinary people. Its nature is gentle and effects are slow, requiring long-term consumption combined with internal nurturing and external training to gradually improve one's constitution, thus compensating for the lack of aptitude.
Improving one's constitution is extremely difficult, and the Spring Rain Pill represents the highest achievement of the Observing Body Sect's millennium-long research in this area, yet its effects remain quite mystical.
Whether one can begin cultivation depends significantly on aptitude, but it is not the sole determining factor. Some cannot enter the realm despite long-term use of the Spring Rain Pill, while truly gifted individuals have no need for it.
