Lu Feng didn't know much about the dark system, although he was with Ao Wuwei for half a year, Ao Wuwei also instilled a lot of common sense in Lu Feng's cultivation, but for the bitter and incomprehensible and extremely rare dark power cultivation, there was no special person to teach, just looking at the codex, Lu Feng was still difficult to understand.

However, the Soul Eater Skeleton mentioned at the end of the exercise aroused Lu Feng's interest.

Looking at the small red skeleton placed beside him, Lu Feng couldn't help but pick it up and play with it, the whole red skeleton was smooth and unusually small, much smaller than a normal human skull, and Lu Feng could hold it with one hand.

However, through the introduction of arrogant exercises, Lu Feng knew that the origin of this seemingly small skull was not simple.

Ao Wuwei mentioned in the exercises, this soul devouring skeleton is Ao Wuwei's use of his own yuan power to transport the soul devouring skeleton for a long time, it is very difficult to sacrifice, want to refine this kind of elemental weapon, usually to find the remains of the strong who just died, use the essence blood of the natal for refining, by absorbing the soul power of the deceased has not dissipated, let the soul eater skeleton evolve, increase the utility of the element, often the smaller the size of the soul eater skeleton, the more powerful it contains.

The Soul Eater Skeleton is divided into white, pink, red, purple, and black, and each time it is advanced to a grade, the greater the utility of this elemental weapon, and the color will change accordingly, of course, the sucking used to evolve the soul power will also increase tenfold and hundredfold, and the exercise mentions that when the Soul Eater Skeleton evolves into black, it can use the power of the element weapon itself to detain the soul of a powerful monk, as for how powerful it is, the exercise is not written, but what Lu Feng wants to do, at least it can detain a strong person with a combined vein!

Looking at the small skeleton, the upper part of the place had already shown a slight purple, Lu Feng sighed in his heart: "I didn't expect Ao Wuwei to actually refine such a spirit treasure, this kind of soul-devouring skeleton refining, to say the least, has also absorbed the soul power of tens of thousands of dead people!"

At this time, the small Soul Eater Skeleton in Lu Feng's hand was unusually quiet, if you look closely, you will find that the small skeleton skull glowing red is like a purple light flowing like a silk of purple light, because Ao Wuwei is dead, the soul imprint of Ao Wuwei in the entire Soul Eater Skeleton has disappeared, this Soul Eater Skeleton has become an ownerless thing, if there is no new owner to use the essence blood to feed within three days, the soul power in the entire skeleton bone will slowly dissipate between heaven and earth.

Looking at this vicious elemental weapon, Lu Feng fell into deep thought, and after a while, Lu Feng finally decided to refine it himself, seeing that a small part of the entire small skeleton had already appeared purple, if it was allowed to dissipate at this time, Lu Feng was really unwilling, and the environment Lu Feng was in now was not very good, and he also urgently needed to increase his combat power through some means.

Although the poisonous energy in Lu Feng's body has disappeared, he can't transport this kind of element weapon for a long time, but with the connection of essence and blood, Lu Feng can also reluctantly drive it.

Lu Feng, who had figured this out, no longer hesitated, and quickly made a cut in his right hand, enveloping the entire red skeleton with his right hand flowing with blood.

Seeing his blood quickly seeping into the small red skull, Lu Feng was not overly alarmed, and the arrogant and inactive exercise mentioned that the early stage of refining this kind of skull must be guided by blood, so that the connection between the user and the element weapon can be deepened when using energy in the later stage.

Feeling the endless flow of blood in his body running down his wounds and being sucked by the Soul Eater Skeleton, even Lu Feng had to sigh at the horror of this skull, until Lu Feng felt that he was gradually becoming weaker, and the demand for blood in the entire skull slowly ended.

All of a sudden, the entire Soul Eater Skeleton suddenly glowed, and the red and purple rays of light became much stronger, and Lu Feng also felt that he had established a connection with the small skeleton in his hand at this time.

Trying to use his divine mind to mobilize the small skeleton in his hand, he saw that the skeleton trembled and rose a distance of one foot, and then fell, although the first time he failed to drive the elemental weapon, Lu Feng still felt overjoyed, Lu Feng knew that if he wanted to exert the true power of the Soul Devouring Skeleton, he would have to go through a long period of practice, and this kind of thing could not be rushed, especially when he did not have any energy to transport the element.

Feeling that his body and mind were a little tired, Lu Feng properly put away the Soul Devouring Skull, and then he looked at a rather quaint book, which was different from the arrogant dark exercises, this book seemed very old, and even some rough edges and broken edges appeared in some places.

But fortunately, the words on the book were barely enough to read clearly, and the moment he picked up the book, when he looked at the four words of the Xuanyin True Scripture written on the book, Lu Feng didn't know what was going on, and he actually had a feeling of familiarity in his heart.

Quickly opened the book and read two pages, Lu Feng's face at this time had been completely replaced by a shocked expression, and gradually later, Lu Feng's face became more and more difficult, and it seemed that he had slowly finished reading the whole book, Lu Feng took out two fragments from his body with an angry face, and the animal skin used for the two fragments was almost the same as the animal skin for the writing of the Xuanyin Sutra.

These two fragments are the Poison Sutra that Lu Feng has been properly preserving, although this cultivation technique is incomplete, but Lu Feng cherishes it very much, this is the fastest way that Mu Hao has progressed in the Shenwu World so far. Until now, the intention of Ao Wuwei has been completely known to Lu Feng.

As early as when he had just collected Lu Feng and went up the mountain, when Ao Wuwei handed over the Poison Sutra to Lu Feng and asked Lu Feng to practice the Ten Thousand Poison Tempering Body, he was playing Lu Feng's idea, and the two pages of the Poison Sutra in Lu Feng's hand were not incomplete, but Arrogant Wuwei deliberately hid the back part.

Now after Lu Feng finished reading the entire Xuanyin Sutra, he realized that what he was practicing was not a poisonous scripture, what was the Ten Thousand Poisonous Tempered Body, it was simply arrogant and incompetent, and the poisonous scripture that Lu Feng had refined was the method of refining the living corpse in the Xuanyin Sutra.

The use of ten thousand poisons to quench the body of the living, so that the living have the ability to absorb the energy in the poison, of which the sarcophagus group is also a key, the entire sarcophagus group is basically a Yin Gathering Array for sacrificing living corpses, which not only refines most of the poison into the Yin Qi. Once the entire formation is opened, the yin qi gathered by all the sarcophagus will invade the divine consciousness of the living corpse, and at the same time, the divine consciousness of the living corpse will be strengthened, and at the same time, its divine consciousness will be obliterated, and the living corpse will be completely turned into a killer who only obeys the orders of the corpse keeper.

The most important point is that after the successful cultivation of the living corpse, he can quickly improve his strength with the help of the energy brought by various poisons, and quickly enter the ranks of the strong with the powerful divine consciousness formed by the Yin Gathering Array.

The benefits of refining this kind of living poisonous corpse with the back of Ten Thousand Poison Peak are self-evident, and it is no wonder that Ao Wuwei would put so much thought into Mu Hao's body.

After slowly closing the Xuanyin True Sutra, Lu Feng's gaze swept a glance at the entrance of the cave leading to the sarcophagus group: "Master, I really didn't expect you to have such an idea, if I was caught by you today, I shouldn't be alive for a few days!
