Cultivation and Alchemy are both vast and profound. Most people can't fully comprehend them in their entire lifetime. Yet Lin Chen's current lifespan is not even a hundred years, and he is also a Loose Cultivator. His attainments in cultivation are very high, but his attainments in Alchemy are not.
For example, the Ancient Heavenly Gods and the Heavenly Emperor have deep backgrounds. With the help of their families, all kinds of treasures, and Elders, in less than a hundred years their cultivation made tremendous progress; their cultivation and Alchemy attainments are both very high. But Lin Chen is a Loose Cultivator; there is no one to help him.
This is also one of the reasons the Ancient Divine Emperors look down on the Sanxiu. Compared to them, the Sanxiu have many advantages, but their overall strength is still inferior to the Emperors of those great clans.
