Three Years

The martial artists of the Divine Martial Continent all knew that the impurities in pills were poisonous.

Even powerful alchemists could not remove this poison. They could only rely on their heaven-defying alchemy cultivation to remove more poison and leave less behind.

In short, the advantages of medicinal pills outweighed the disadvantages. Martial artists could not do without medicinal pills.

No expert could grow without relying on medicinal pills. Even heaven-defying experts had to use medicinal pills.

However, refining medicinal pills was difficult. Very few people could refine medicinal pills.

Among ten thousand martial artists, not a single person could refine pills. The higher the level of the pill, the harder it was to refine. Some pills were only heard of in legends, but had never been seen in reality.
