Li Guchan continued: "The difficulty in planting spiritual medicine underground in the past was the 'Purgatory Light.' Even Martial Cultivators of the sixth or seventh realm face the risk of demon transformation if exposed to the 'Purgatory Light' for over three months. If their emotions fluctuate slightly, they might fall into the category of demons, which is why the Sky Pond troops of various nations must rotate regularly."
"Secondly, various mechanisms and the herbs themselves can also undergo mutations. Mechanisms can develop spiritual sense, and herbs contaminated by large amounts of Purgatory Light experience changes in efficacy, often driving people mad."
In this regard, the Mechanical God Temple excels at crafting various mechanical devices. When placed in Sky Pond for just a few months, these devices begin developing spiritual wisdom.
