The mutated pure yang spiritual power cultivated by Zhu Lingwu was placed on a tiger for experiments by Zhu Lingwu.

As a result, Zhu Lingwu was very satisfied. Zhu Lingwu found that although the power of the transparent cold flame he released was different from that of Xuanming Youhuo, it did not burn immediately after blood was seen, but it also had a similar effect, and this effect was even more concealed.

Under the observation of Zhu Lingwu's soul, the transparent cold flame released by Zhu Lingwu reached the tiger's side, and under the drive of Zhu Lingwu's mind, it penetrated into the tiger's body.

After it touched the tiger's blood, it did not start to burn immediately. At first, Zhu Lingwu was very disappointed and thought he had failed.

But soon Zhu Lingwu made a new discovery. The transparent cold flame he released entered the blood of the tiger, as if he was absorbing the vital energy contained in the blood shadow of the tiger little by little. As the vital energy was absorbed, it became more and more unstable, and eventually it started to burn.

It seems that the transparent cold flame released by Zhu Lingwu also seems to have similar effects as Xuanming Youhuo, and the effect is more secretive. It seems to have a slow penetration effect.

It will not burn immediately at first, so it will not be discovered immediately. However, this cold flame can flow in the blood for a period of time, and it seems that it will take a certain amount of accumulation before it will burn in the body.

Moreover, the areas of the body it flowed through before would leave a little cold flame. During this period of flow, the cold flame had already spread to many areas in the body, and might even have flowed into the heart.

So when it explodes, it will explode at the same time in many places in the body, and some are still in the organs and cannot be removed at all. The tiger doing the experiment will burn half of its body at the same time.

After about half a stick of incense, the tiger, more than two meters long, had been burned into a white bone.

According to the original effect of Xuanming Youhuo, the skeleton of the creature that was burned to death by Xuanming Youhuo will become the special magic material of Xuanming Sect under the special refining of Xuanming Youhuo. According to the Xuanming Sect's weapon refining technique, this kind of white bone can be used to make many things.

Now, the white bones of this fierce tiger have undergone similar changes under the calcination of Zhu Lingwu's transparent cold flame after the bursting of Zhu Lingwu. This effect is similar to that of Xuanming Youhuo.

But I don’t know yet whether this transparent cold flame can hide for a while without knowing it, and then suddenly occur?

Unfortunately, Zhu Lingwu couldn't find anyone to do this for the time being, and no one dared to experiment for him. He stayed in the family's ancestral land, Wubao, so he couldn't find a clan member to try it out.

If that person could not stop the internal combustion of this transparent cold flame and was burned to death, how would Zhu Lingwu pay him a life? Besides, Zhu Lingwu couldn't explain how he learned this spell.

But when Zhu Lingwu saw that the transparent cold flame he released was effective, he had already made a decision. He took this transparent cold flame, perhaps now it should be called the shadowless Yin Fire, as a spell that he concentrated on studying when practicing the fourth level of Qi.

This shadowless yin fire is no matter what, it is a kind of fire spiritual power. The heart of the human body belongs to fire, so Zhu Lingwu decided to refine Qi fourth level to be the first to condense innate spiritual power, which is his own heart.

In fact, it is not completely accurate to Zhu Lingwu when talking about this level of the fourth level of Qi training, because the Five Qi Guiyuan Heart Art practiced by Zhu Lingwu has actually condensed a point of innate fire spiritual power to absorb and transform the spiritual energy of heaven and earth in Zhu Lingwu's heart.

However, this innate fire spiritual power point is relatively weak and has a relatively single effect. It is different from the process of spiritual transformation of the heart at the fourth level of Qi training.

But with this foundation, it can help Zhu Lingwu reduce a lot of trouble, which means that Zhu Lingwu now has the foundation for the fourth level of Qi training.

This is also the significance of the high-level Qi Refining Heart Method, the Five Qi Guiyuan Heart Technique. In fact, Zhu Lingwu has not only the foundation for the fourth level of Qi Refining, but in fact he has already had a foundation for the fifth level of Qi Refining, and even the subsequent Qi Refining Realm.

It means that the advanced qi refining mind method has been preparing for the later stage of qi refining since the beginning of cultivation, such as the body rhyme spiritual light realm of the fourth level of qi refining.

There is also the fifth level of Qi refining spiritual array that first becomes realm, which is actually to condense and transform all the five internal organs in the body with spiritual power into spiritual organs, and then use this to transform them into the five internal organs of the human body to form the natural spiritual array of the human body.

The five organs of the human body are originally necessary organs for human survival and are the source of life energy. After transforming them, it is naturally of great significance for the Qi Refiner to transform his body from an mortal fetus into an acquired spiritual body.

But for Zhu Lingwu, he has been doing this since he practiced the Five Qi Guiyuan Heart Art, and he has done more and better, because the Five Qi Guiyuan Heart Art not only condenses spiritual power points based on the five elements attributes of the human body's five internal organs, but will condense spiritual power points all over the body.

In turn, accelerating the process of building foundations into acquired spirits can also greatly increase the chances of building foundations for Qi Refiners. After all, different Qi Refining Realms seem to be very simple to practice, but it is not that easy to operate.

So now Zhu Lingwu has determined that his goal of practicing the fourth level of Qi training is to reconcile his heart with spiritual power, but it is not easy to achieve this goal.

It has been more than half a year since Zhu Lingwu broke through the third level of Qi refining, but Zhu Lingwu felt that his heart had not yet achieved one-tenth of it.

To condense the heart into acquired spiritual objects, you must use innate spiritual power to clean it again and again, so that the turbid substances in the heart can be eliminated and the biological fluids in the heart can be replaced with spiritual power.

Moreover, human organs like the heart are living creatures, so they naturally cannot be forced to refine them by refining weapons using domineering means, so this transformation process requires even more caution.

Fortunately, when condensing the five internal organs in the body, it is not necessary to divide the special innate five elements spiritual power. Zhu Lingwu only needs to drive the mutated pure yang spiritual power in the body, otherwise this process will be more troublesome.

But Zhu Lingwu still needs to make up his mind to solve one thing, that is, Zhu Lingwu practiced the Nine-Turn Thunder Body Rewarding Technique, and the essence and blood condensed with acquired power are also hidden in the ventricle.

Now that Zhu Lingwu is going to attack the heart, how should he deal with the essence and blood containing rich acquired electricity?

Now Zhu Lingwu has felt a little trouble. Part of the innate spiritual power he drove into the heart was absorbed by the acquired electricity in the ventricle, which inevitably increased the difficulty of Zhu Lingwu's heart refining.

This acquired spiritual power nurtured in the essence and blood was originally used to practice the Nine-Turn Thunder Body Rumor Technique to impact the innate realm, but now Zhu Lingwu can already refine his qi. So does this acquired spiritual power still need to be retained?
