"Mom, are herbs with a history of 1000 years extremely scarce?" Qing Shui asked, feeling uneasy at the expression on Qing Yi's face.
"Herbs with a history of 100 years, or even 800 years, can be regarded as ordinary medicinal materials as long as they're not 1000 years old. Only when a herb's age reaches or exceeds 1000 years does it become considered an extremely valuable medicinal herb. There's just a single grade difference between ordinary herbs and precious herbs, but the gap between these grades is like the distance between heaven and earth! For instance, many alchemists tend to concoct pills and pills to increase cultivation or prolong life. In the mixtures of these precious pills, every piece of herb and ingredient must strictly meet the standards outlined in the formula. If an alchemist uses a 999-year-old Lingzhi instead of a 1000-year-old Lingzhi, then the pill's effect will vanish, and the mixed medicine is most likely to fail.
