Zhu Lingwu repeatedly used his soul thoughts to investigate the innate spiritual power accumulated in his mouth. In fact, there were not many Yin and cold death energy contained in these innate spiritual powers.

But if Zhu Lingwu sucked them into his body regardless of the scruples, or even converted them into his own spiritual power according to the method of the Five Qi Reincarnation Heart Skill, it would probably leave hidden dangers on Zhu Lingwu's body.

Not to mention that over time, this body will damage the life span under the invasion of the cold and dead energy of the Yin and Cold Qi. Even the innate spiritual power condensed by Zhu Lingwu will also produce impurities, which will cause endless troubles.

No wonder that no immortal cultivator in Xuanming Sect had ever thought of practicing in this way before. On the one hand, it was a shackle on the concept and thought, and on the other hand, it was also because of the existence of these cold and dead energy.

But the ghost magic weapon like Xuanming Ghost Head inevitably needs to absorb the yin and cold death energy to condense the skull and maintain the existence of innate spiritual power. This is as important as weaving a golden thread of jade.

If the Yin and Cold Death Qi is removed, the Xuanming Ghost Head will not be the Xuanming Ghost Head. You must find the right materials to carry innate spiritual power again, which is completely another method of refining magic weapons.

"It's a pity! Why can't it work? I failed because of Shan Jiuren. Could it be that I could only give up because of this? If I didn't use this method, how should I practice? Wait, maybe I can filter it like this!"

Of course, Zhu Lingwu was unwilling to give up on the solution he had come up with painstakingly, but it was useless for such reasons, so he soon came up with another idea.

Then a piece of electric flowers suddenly flashed from Zhu Lingwu's mouth. The innate spiritual power with the yin and cold aura, under the filtering of these electric flowers, the yin and cold aura inside suddenly disappeared like a snowflake encountering a fire.

Zhu Lingwu couldn't help but smile smugly on his face. He could finally swallow these innate spiritual power with confidence.

With the continuous transmission of the innate spiritual power, and the filtering of the arc network in Zhu Lingwu's mouth, it was indeed greatly improved Zhu Lingwu's qi refining efficiency after being introduced into Zhu Lingwu's body.

This is equivalent to letting five Qi Refiners at the third level help Zhu Lingwu absorb the spiritual energy of heaven and earth to practice. Zhu Lingwu was overjoyed and said, "Haha, it's great! In this way, the five-year agreement may be realized! But how should I make excuses at that time? Uh, I'm so stupid, what excuses to make, just tell me this method! Who else can do this method except me!"

Zhu Lingwu was satisfied with the innate spiritual power introduced into his body. These innate spiritual powers themselves were divided into different five elements attributes, so after entering his body, the efficiency of being absorbed was very fast.

Following the spiritual power circulation route he established according to the Five Qi Guiyuan Heart Skill, these innate spiritual powers soon reached the innate spiritual power point in Zhu Lingwu's body. Almost no matter how the organ where the innate spiritual power point is, they can be transformed into Zhu Lingwu's own spiritual power, and then merge into the innate spiritual power flowing in Zhu Lingwu's body.

But with the refining of these innate spiritual powers, Zhu Lingwu still felt that the pure yang spiritual power he refined with these innate spiritual powers had a little wrong taste.

Zhu Lingwu has been refining Qi for three days. Although the previous qi refining efficiency was extremely low, through the method of the Five Qi Guiyuan Heart Art, Zhu Lingwu has transformed his innate spiritual power into pure yang spiritual power.

However, following the method of the Five Qi Guiyuan Heart Art, except for the consumption of innate spiritual power condensed in the body, the remaining pure yang spiritual power is really thin.

But with this feeling of pure yang spiritual power, Zhu Lingwu knew what the pure yang spiritual power originally cultivated through the Five Qi Guiyuan Heart Art tasted.

Now, Zhu Lingwu feels that the pure yang spiritual power he has cultivated tastes a bit different from the original pure yang spiritual power.

Okay, let’s give a simple metaphor. The original pure yang spiritual power was like the scorching sun at noon in summer, but the pure yang spiritual power cultivated by Zhu Lingwu now has a bit of feminine feeling like moonlight.

Although sunlight and moonlight are all derived from the sun's light and belong to light energy, the energy properties they show are still different.

"What does this feel like? No, I will definitely not practice like this! Otherwise, I would try it with the Five Elements Transformation Yuan Gong. Fortunately, although these two are of different grades, they are all pure yang powers!"

Zhu Lingwu muttered to himself, and he was really worried about what consequences he would have to do.

So after a thought was made in mind, Zhu Lingwu was actually planning to use the Five Elements Transformation Yuan Gong Technique obtained from the Family Transformation Academy to try it out. Anyway, although the Five Elements Transformation Yuan Gong is a low-level qi refining technique, the ones you practice are pure yang spiritual power.

Originally, with Zhu Lingwu's lower-grade innate spiritual vein qualifications and using this lower-grade qi refining technique, it might take several days to develop a trace of pure yang spiritual power, but now it is a bit different.

With five Xuanming Ghost Heads, he used his own condensed innate spiritual power to help Zhu Lingwu absorb the spiritual energy of heaven and earth, and even directly transformed it into innate spiritual power to transport it to Zhu Lingwu. This concentration of spiritual power, even a lower-grade qi refining technique, should produce good qi refining efficiency.

With the help of five Xuanming Ghost Heads, Zhu Lingwu's current level of qi refining is probably a bit faster than that of a qi refiner with the highest-grade innate spiritual vein qualifications.

At least before Zhu Lingwu reaches the third level of Qi Refining, Zhu Lingwu can enjoy this plug-in qi refining efficiency. If this method is feasible, even after Zhu Lingwu reaches the third level of Qi Refining, he can use this method to have faster qi refining efficiency than ordinary people.

More importantly, Zhu Lingwu suddenly realized that as long as the innate spiritual power cultivated by the Five Elements Transformation Yuan Gong is also the pure yang spiritual power cultivated by Zhu Lingwu now, Zhu Lingwu can go to the family's Transmission Academy to ask what the pure yang spiritual power cultivated by himself is.

Anyway, it just needs to check the spiritual power attributes you have cultivated, and it has nothing to do with what kind of exercises you have used to practice.

Of course, the most important thing depends on the innate spiritual power you cultivated with the Five Elements Transformation Yuan Gong. Is it the pure yang spiritual power now?

So Zhu Lingwu couldn't help but think about the running technique of the Five Elements Transformation Yuan Gong in his mind, and then stopped the spiritual running method of the Five Elements Transformation Yuan Gong, and then started to operate in his body according to the spiritual running method of the Five Elements Transformation Yuan Gong.

It is indeed a simple method of refining qi. Zhu Lingwu followed the simple method of running spiritual energy, and continuously operated the innate spiritual power introduced into his body.

Then, it was really a slow process to transform these spiritual powers into the pure yang spiritual power that originally existed in one's body.

Thanks to Zhu Lingwu's plug-in for Xuanming Ghost Claws, Zhu Lingwu nodded with satisfaction after half a stick of incense.

Although the cultivation efficiency of the Five Elements Transformation Yuan Gong is indeed very low, the pure yang spiritual power condensed in the end is the same as the pure yang spiritual power condensed in the Five Qi Guiyuan Heart Skill.
