Although there were only four steps, the distance between them was very long. Just the early preparation for the pill condensation would take a very long time.

However, according to Ye Haoxuan's conjecture, that senior must have had a problem with some of these four steps, which resulted in him being unable to successfully refine the Spirit Profound Stone no matter what method he used.

Sure enough, after Ye Haoxuan finished reading all of the refining experiments recorded in the letter, he analyzed many of the shortcomings as well as the unfathomable scientific concepts of this world.

For example, during the process of condensing the core, the senior would intentionally decompose the Spirit Control Beast's corpse and then soak it in the medicinal liquid to reduce the rate at which the corpse decayed, allowing the Beast Spirit Pill to fully absorb the element within the corpse.
