Because all he needed to do was to cultivate continuously within the Gathering Essence Array, the array would constantly make the mana in He Song's body become more refined.
Even though He Song changed his cultivation skill multiple times, he no longer had to worry about the issue of mana impurity.
By now, He Song had been cultivating within the Gathering Essence Array for a full two years.
In these two years, as He Song continuously cultivated, the mana within his Golden Elixir became increasingly pure due to the effect of the Gathering Essence Array.
As the mana increased and became purer, this naturally caused a heaven-and-earth shift in He Song's own power level.
Moreover, after two years, this improvement still showed no signs of halting.
Until now.
The Gathering Essence Array was still providing He Song with significant enhancement.
