Since ancient times, most of the Heavenly Treasures and Earthly Five Deities have been seen, and they are well-traveled and knowledgeable. Furthermore, they also know the characteristics of the Divine Realm and the cultivation realm beneath the Divine Realm, and how to break through them. Lin Chen only had the confidence to create a formula that could break through the realm in a short time after meeting various conditions. It's ineffective for others.
But even so, crafting medicine pills is not easy. The raw materials for concocting pills must be precious and rare. Obtaining them is not easy, but at least it's easier than finding Heavenly Treasures and Earthly Treasures, which can break through the realm in a short time. Meeting people of such caliber as Heavenly Treasures and Earthly Treasures is too difficult. This is very rare after ancient times, as some have already been used by others.
