Just imagine, Xin Xing had managed to find a master in the field of old arts, but in the end, because of practicing the secret scriptures passed down by the Taoist ancestral court, he practiced himself to death, and his internal organs rotted away.
If he could enter the inner scene of Taoism, this kind of thing would never happen.
Because, in the inner scene, you can clearly see the changes in the internal organs, and there are mysterious factors falling down, nourishing the internal organs, even if you fail to practice, you will not die.
