The principle behind the secret art of "Profound Soul Refinement of Demons" turned out to be a body refining method, or rather, a demon refining art. Its core theory is to refine oneself into the body of a demon beast. Seeing this, Zhang Ling suddenly remembered a book he had seen in the Haoyuan Sect's library that introduced cultivation methods. It recorded the cultivation methods that had appeared from ancient times to the present. Besides the well-known Immortal Dao, Demonic Dao, and the less common Buddhist and Confucian paths, there were also Body Refinement cultivators and the Ghost Dao. Among the Body Refinement cultivators, the Immortal, Demon, and Buddhist paths all had similar techniques for strengthening the physical body. However, among the Body Refinement cultivators, there was also a cultivation method called Demon Cultivation. It was difficult for Body Refinement cultivators to advance, and the shackles of the physical body were not easy to break through. Some people took a different approach, directly taking materials from powerful demon beasts and fusing them into their bodies to enhance the strength of their physical bodies. After all, generally speaking, the physique of demon beasts is much stronger than that of humans, making this a shortcut to cultivate the physical body. In the beginning, some powerful cultivators emerged using this method, but this method also had many drawbacks. The first is that transplanting parts of a demon beast's body onto a human body would cause great rejection, often with only one in a hundred succeeding.
Very few cultivators could fuse with demon beast materials and survive, and even if they succeeded, their strength might not necessarily increase much. The second is that this cultivation method would turn people into half-demon bodies, which was unacceptable to some cultivators. Therefore, these demon cultivators were rejected by immortal cultivators and often seen as heretics. Their inheritance was extremely rare, and they were almost extinct. The third is that to reach the level of high-level cultivators with this cultivation method, one must also fuse with a demon soul. This is the most dangerous. One mistake would cause a person's mind to become chaotic, turning them into a monster that only knows how to kill. The vines on Zhang Ling's left arm could also be seen as a type of plant demon beast, yet they were strangely fused into his body. This is somewhat similar to the demon cultivator's fusion of demon beast materials, although he doesn't know how these vines fused into his body. However, once the vines are severely damaged, they will absorb the power of his entire body's aura. This was already a hidden danger. Now, there is more baleful aura in his body. The "Profound Soul Spirit Demon Art" is the secret method for demon cultivators to fuse demon beast materials. The series of secret methods recorded above, once successfully cultivated, would turn those demon beast materials into a part of oneself. Zhang Ling's idea to solve the baleful aura in his body was to cultivate the Profound Soul Refinement of Demons, completely turning the vines parasitic on his arm into a part of himself, and then using the vines to absorb this baleful aura. This method is feasible because after carefully examining the state of the baleful aura in his body, he discovered that most of these baleful auras were transformed from the blood talismans that Wei Shen planted in him. These blood talismans themselves were designed to target the vines in his body. This is the Qi and blood condensing technique recorded in the Human Origin Baleful Elixir. These blood talismans are used to control the vines parasitic on his body, to absorb the blood Qi power of the body to condense the baleful elixir. This is the role of the blood talismans. Now that these blood talismans have lost control, the baleful aura gathered in them remains in Zhang Ling's body. These blood talismans are transformed from Wei Shen's blood essence, even if he now knows the principle, he cannot eliminate them unless Wei Shen is resurrected. Therefore, he came up with the idea of the Profound Soul Refinement of Demons. However, Zhang Ling is still hesitant about whether to use this demon refining art to solve the baleful aura in his body. Although this is a method, it is also a way of fighting poison with poison, and he is not sure whether there are any hidden dangers. In the following time, he continued to study the secret art on the silk scroll while refining the corpse bear. Now his strength can only发挥 seven or eight 成, greatly limited, and this corpse bear is a zombie body, its strength is comparable to the early stage of Foundation Establishment. Refining this corpse into a puppet is equivalent to having an additional Foundation Establishment stage strong fighter.
With this idea, Zhang Ling returned to the underground rift again and began to refine the corpse bear. As for how he controls this corpse bear monster, it is simple as long as he cultivates the Soul Division Technique. In the world of immortal cultivation, this is the most common method to control puppets. As long as a part of the divine sense is separated and transformed into a divine thought, it can be integrated into the corpse bear's body and used to control it. The Soul Division Technique is recorded in the nameless soul refining technique on the black paper, which is much simpler than the Soul Splitting Technique he used to solve the Soul Devouring Insects. Inside the underground cave filled with Yin Qi where the Willow of Growing Ghosts grew, Zhang Ling sat cross-legged with a huge black coffin in front of him, surrounded by wisps of black air. Zhang Ling's lips moved slightly, chanting a spell in a low voice, and then he stretched out his right index finger and pointed it at his brow. After a moment, his fingertip began to glow, and a gray light shadow as thin as gossamer floated out from it. After this gray light left his fingertip, it circled around him first. Then, with a whoosh, it disappeared into the black coffin in front of him. Without seeing Zhang Ling make any movements, a thought flashed in his mind, and suddenly the coffin emitting black air in front of him shook, and a two-zhang tall monster slowly stood up. The monster was emitting corpse Qi all over its body, and in the originally empty eyes of its hideous head, a faint green light lit up. It leaped two zhang high and landed on the ground with a thud. Then, it raised its claws, which were emitting a verdant cold light, and suddenly grew several inches long, waving them a few times in the air, making crackling sounds, looking like a real second-order demon bear. Zhang Ling's face was a little pale, but a smile appeared on the corner of his mouth. This was the first time he had used the "Soul Division" technique. The so-called soul division, as the name suggests, refers to separating a part of the original complete divine sense and attaching it to other things for manipulation. This is actually similar to manipulating a magic weapon, but manipulating a monster as powerful as the corpse bear naturally requires a lot of divine sense. What's different about the senior brother and ordinary puppets is that although it is a zombie body, it is not an inanimate object, and it can advance by devouring flesh and blood and Yin Qi. Ordinary Soul Division Techniques cannot completely control this type of monster. This is what he learned after carefully examining the cultivation experience left by Wei Shen. In addition to the Soul Division Technique control, other types of restrictions must also be placed on the corpse monster. However, he does not know these restrictions now. He can only use the Soul Division Technique to simply control this corpse bear, and it will not be too late to find relevant restrictions in the future. There are actually many related spells, and some demonic and ghostly cultivators also refine corpses and other puppets. In the following time, he stayed in the underground rift, familiarizing himself with the control of the corpse bear. After a period of time, this corpse bear formed a good combat power under his control. It's just that this corpse bear is dilapidated, especially with a large area of exposed skin on its back, where the defense is greatly reduced, which is a flaw. Thinking that the corpse bear could advance by devouring flesh and blood and Yin Qi, Zhang Ling fed the broken body in the small coffin to the corpse bear. Sure enough, after the corpse bear devoured the broken body, black hair grew back on the exposed skin. The original black hard hair began to glow with a purplish-brown spiritual light. Zhang Ling sensed it, and the strength of the corpse bear's body had increased again. It seemed that Old Ghost Wei did not lie, and the broken body was originally a corpse monster stronger than the corpse bear. With this corpse bear, Zhang Ling's strength can be said to have increased by more than double. Next, he began to consider his future plans. ……
