One can also better experience the heavens, the earth, and the dao through this rigorous process. It will greatly promote a fifth tier Jindan Dao cultivator's progress in becoming one with his or her Jindan. So much so that many people have found their own way of becoming one with their Jindan through refining immortal medicines.

"Familiarity with oneself is an important step to refine your Jindan. Although I have the best Jindan Condensation Wondrous Art, and an abundance of Golden Essence Pills, I still need to become more familiar with myself and realize the existence of dao in order to reach the fifth tier of the Jindan Dao Realm. Otherwise, I will be stuck in this bottleneck forever.

"There are hundreds of thousands of fourth tier Jindan Dao cultivators in the Common Sword Domain, and most remain at this tier for many decades. With such a long time, no matter how slow they are in refining their Jindan, they can also reach the breakthrough point of the fifth tier. The reason why they cannot reach the fifth tier is because they lack the understanding of dao. They are unable to be familiar with themselves to become one with their Jindan, to understand the heavens and earth."
