So his sun's yang energy quality increased exceptionally and his body become stronger and his energy soul also strengthened a little bit. Both his energy and physical cultivation increased a little bit.
Wang Wei can feel that this improvement won't work for a long time because he requires more pure yin energy to increase the quality of his yang energy.
Every time after cultivation using the pure yin energy the previous level of yin energy will not help him. So Wang Wei always spends more time refining the pure yin water and putting it in the furnace.
As time passes the quality of the Yin energy needs to increase but he can't do anything about it. Even if he knows about it he can't do anything other than increase the quality of the pure yin energy as higher as possible. But that isn't a solution for a long time.
