Previously, many side peak physicians attempted to find ways to cope with the Law-Devouring Yin Insect, but without exception, all efforts were fruitless, and there was even an instance of someone accidentally contracting the Law-Devouring Yin Insect and becoming a mortal.
Since then, ordinary physicians dare not touch the Law-Devouring Yin Insect. Luckily, it can be resisted with magical talismans, as long as it doesn't invade the body and meridians through a wound, no issues will occur.
Similarly, regarding the Law-Devouring Yin Insect, neither Feixian Peak nor other side peaks have much recorded about it, and it hadn't even appeared in the Cultivation Realm at Deadman Peak until a few years ago; hence, it's likely from an external Gu Raising Technique.
