He only needed to spend time on elixir refinement and then purchase the spirit medicine required to refine such spirit elixirs from his Guest Elder Token.
In this way, He Song, while researching these spirit elixirs,
compared to other cultivators, naturally had a bit of an advantage.
However,
according to He Song's plans,
once he could improve his success rate in refining these spirit elixirs to the point where it was financially viable,
his focus would then shift to the array tao.
At the very least, he would wait until he could set up a Nascent Soul Gathering Spirit Array before turning back to delve deeper into the Elixir Tao.
Otherwise, if he cultivated for too long in a place like the Sun Faction where spirit Qi was thin, he might indeed slow down He Song's progress in cultivation.
Fortunately, although the Sun Faction was said to have thin spirit Qi, He Song had also set up a Golden Elixir Spirit-Gathering Array in his own cave mansion.
