The Mortal World's summary of the alchemy process can be boiled down to the following steps:
Firstly, the decomposition and purification of the ingredients; secondly, mixing different ingredients in stages; then refining the different components to obtain a new structure (the properties of the medicine); finally, stabilizing the structure (refining the elixir).
However, the summary from the Mortal World has a premise: it eliminates the factors of Immortal Spirit Qi and Luck. If these two factors are included, everything becomes unpredictable.
In the history of the Creation Temple, there has been no shortage of events where sudden Great Fortune descended upon someone, causing the elixir to be formed as soon as the pill furnace was ignited, and each pill appeared as if tattooed.
