Putting aside distracting thoughts, Gu Fenghua concentrated his mind and began to operate the exercises, and the holy qi flowed in the meridians. Suddenly, Gu Fenghua was surprised to find that the flow of the holy qi was obviously smoother than before, and the speed at which the heaven and earth spiritual qi was inhaled into the body, refined, and integrated into the holy qi was also significantly faster than before.

"What's going on?" Gu Fenghua didn't rush to cultivate, but stopped.

Concentrating inwardly and probing carefully, Gu Fenghua was shocked to find that his holy qi had become nearly twice as pure as before, as if all the impurities had been purified once.

Gu Fenghua almost couldn't believe it, and after concentrating on it carefully, he finally determined that he was not "looking" wrong, all the holy qi had been completely purified once, and for a while, Gu Fenghua was so surprised that he almost jumped up.

You must know that there are impurities between the aura of heaven and earth, and in the process of cultivation, it is inevitable that impurities will be generated, no matter how subtle and mysterious the exercises are, they cannot be avoided, and the higher the cultivation, the more impurities there will be. The existence of these impurities will also affect the speed of cultivation sooner or later, affect the use of holy qi, and even reach the limit of the capacity of the meridians, thus becoming the biggest bottleneck affecting the improvement of cultivation.

It is not an easy task to remove these impurities, as far as Gu Fenghua knows, there is no exercise or holy pill that can quickly remove these impurities, the best way is to break through the promotion, as long as once promoted, the meridians will be greatly broadened and become stronger, and the influence of these impurities will also be ignored in the past.

However, who in this world can improve their cultivation without limit and continue to be promoted, so these impurities, sooner or later, will still become one of the biggest obstacles to the Holy Master.

Many Holy Masters have been limited to the bottleneck for many years, and they can't make any more progress in their cultivation, and they can't even break through when they find an opportunity, just because this impurity exists in the Holy Qi, as long as these impurities can be removed, the Holy Qi can continue to improve, and even without looking for an opportunity at all, they can forcibly break through!

Gu Fenghua's holy qi was inexplicably purified, how could he not be ecstatic?

After a while, Gu Fenghua's mood calmed down, and he began to wonder again, how could the holy qi be purified all of a sudden since yesterday was the same as before, and what was the reason for this.

Recall carefully, on this day, she had neither cultivated nor taken any heavenly treasures or elixirs, and the only thing that might be related to cultivation was the art of refining weapons.

Gu Fenghua's heart moved, and he recited the heart trick again, and typed out the refining handprint taught by Ghost Yezi, but this time, Gu Fenghua no longer focused on this refining handprint, but looked inward, carefully observing the changes in the holy qi.

Soon, Gu Fenghua noticed something unusual, at the same time as the holy qi was circulating, the phoenix power that seemed to have been integrated into it became active, and in the meridians, there was a faint red light, as if a flame was burning, and the remaining impurities in the holy qi also dissolved in the flame little by little.

It turned out that the same as the Dan Dao technique of the Ethereal Cloud Valley, the method of refining the Ghost Yezi could also control the power of the phoenix, and it could also purify the holy qi. Gu Fenghua finally found the reason.

However, she soon discovered that no matter how much she recited the heart trick and made the hand seal, the remaining impurities in the holy qi could not be removed, and it was obvious that she had reached the limit, which was of course not the limit of the power of the phoenix, but because she could not practice the art of refining at home.
