The difficulty of refining the Great Overarching Pill and the Overarching Heaven Pill was similar. However, the Overarching Heaven Pill was far more valuable than the Great Overarching Heaven Pill due to several reasons. Only a prominent Celestial Alchemist was able to refine the Overarching Heaven Pill, a prominent Celestial Pill. There were far fewer prominent Celestial Alchemists compared to mediocre Celestial Alchemists. Apart from that, the formula for the Overarching Heaven Pill was not as known compared to the formula for the Great Overarching Pill. The Great Overarching Pills were not as rare, even forces from an intermediate-rank Celestial Kingdom would have a few of them.
