It can be said that ancient medical techniques are a higher form of medicine, so there's one important thing: one must understand traditional Chinese medicine. This is both a cover and a necessity to master, given that Liu Chen has limited knowledge in medicine. For example, there is a method of acupuncture here to treat a difficult-to-cure disease, but Liu Chen currently doesn't know acupuncture, so he feels he must find time to study traditional Chinese medicine.
This time, he inherited the ancient medical techniques by chance, perhaps he was indeed quite lucky, otherwise, how could he have this opportunity.
While browsing the ancient medical techniques, Liu Chen suddenly saw a pill recipe recorded in the ancient medical techniques that greatly interested him. He couldn't recognize the text, but he could discern from the writings that it was indeed a method related to strange fire pill formula.
