Inside the inn.
Zhang Ling was holding the treasure pearl he had exchanged with the black-robed man. It was engraved with many black spiritual patterns, and the entire pearl was trembling slightly.
As the pearl shook, green light flickered inside, revealing a translucent, grey-green miniature turtle phantom.
This pearl was not a special treasure, but merely a soul-hosting magical artifact refined from top-grade cold jade. The demon soul of a seventh-order Azure Water Turtle was sealed inside.
Zhang Ling carefully sensed this demon soul with his divine sense, checking it several times for any anomalies. Then, he grinned, and a black, circular wooden牌(木牌: tablet/sign) appeared in his hand.
The wooden 牌(木牌: tablet/sign) was only the size of a thumb and looked very small, but it emitted a faint layer of spiritual light.
With a slight thought, the wooden 牌(木牌: tablet/sign) flew into the air. As several mysterious runes struck it, the spiritual light on the wooden 牌(木牌: tablet/sign) flickered a few times and turned into a strange yellow-green color.
Then, he pointed a few times at the round pearl in his hand, and seven or eight chains of yellow spiritual power rushed into it, directly pulling out the mini turtle to lodge soul that was residing inside.
This demon soul struggled constantly, sometimes turning into a solid form, sometimes into a hazy, illusory state, and at the same time, it was sometimes big and sometimes small. A complete seventh-order Azure Water Turtle demon soul was indeed quite spiritual.
As soon as this demon soul escaped the bondage of the round pearl, it immediately emitted a thick soul power, seemingly wanting to break free.
Zhang Ling had no expression on his face. As his ten fingers flicked slightly, the chains congealed from spiritual power directly dragged this demon soul into the wooden 牌(木牌: tablet/sign).
Instantly, the spiritual light on the wooden 牌(木牌: tablet/sign) flashed, and it turned back into a black wooden 牌(木牌: tablet/sign).
At this time, the spiritual light it emitted turned grey-green, and at the same time, the Azure Water Turtle's demon soul also emerge out.
Then, Zhang Ling condensed out rune and struck the tablet/sign , temporarily sealing the seventh-order Azure Water Turtle's demon soul inside.
Although the circular wooden 牌(木牌: tablet/sign) was very small, it was a soul-hosting magical artifact refined from a small piece of Soul Nurturing Wood. Any spiritual body residing inside could maintain its spirituality for a long time.
It was much more powerful than the magical artifact refined from cold jade next to it.
Doing so was naturally to maintain the spirituality of this demon soul for a long time, which was related to the secret technique he was about to cultivate.
Zhang Ling pondered, and with a flash of spiritual light in his hand, two more wooden 牌(木牌: tablet/sign), one large and one small, appeared.
The two wooden 牌(木牌: tablet/sign) were also soul-hosting magical artifacts refined from Soul Nurturing Wood.
The smaller wooden 牌(木牌: tablet/sign) was also only the size of a thumb, with a faint miniature turtle phantom floating on it. It also sealed a fifth-order Rock Turtle demon soul inside, but it was not as good as the Azure Water Turtle demon soul he had just obtained.
The larger wooden 牌(木牌: tablet/sign), on the other hand, was the size of a palm, densely engraved with some blood-colored runes. At the same time, this wooden 牌(木牌: tablet/sign) was constantly trembling, also revealing a miniature turtle.
But this turtle's body was dark cyan, looking extremely solid, its eyes were blood-red, with a ferocious and fierce look, and it was constantly hissing at Zhang Ling as soon as it appeared.
A cold wind transformed from soul power instantly filled Zhang Ling's face.
This made Zhang Ling frown slightly.
The dark black turtle looked like it had a solid body, but it emitted a powerful divine soul power. This was the Black Turtle demon soul that possessed the strength of a transforming demon beast.
After he walked out of the Tianyuan Secret Realm, he immediately pulled this Black Turtle demon soul out of the Yin Soul Banner and re-sealed it on the Soul Nurturing Wood.
Why re-seal it? Because there were many remnant souls originally existing in the Yin Soul Banner, and a large part of them were actually devoured by this Black Turtle demon soul, almost allowing the demon soul to escape.
If he hadn't discovered it early, his life might have been in danger. Thinking of this, Zhang Ling couldn't help but feel a little afraid.
This was not a joke. If this powerful Black Turtle demon soul escaped, he would not be able to control the Black Turtle main body that had been put into the Two appearance gourd.
As for the blood-colored spiritual patterns engraved on this Soul Nurturing Wood, it was not an ordinary sealing technique, but a Soul Refining Technique from the Underworld King Art, a Ghost Dao cultivation technique in his hand.
Even so, it seemed that this seal was not reliable at the moment.
The main reason why he didn't directly extinguish this demon soul was naturally because he wanted to control this Black Turtle.
This Black Turtle had the strength of a transforming demon beast. Although he had sealed the beast's demon soul, demon core, and flesh separately.
But once he could control this beast, it would be equivalent to having an henchman comparable to the Nascent Soul level. Zhang Ling naturally didn't want to give up such an opportunity and lure.
As for how to control the Black Turtle, Zhang Ling also had some ideas. This would still depend on the Second Nascent Soul Secret Technique, the Mysterious Female Transformation Spirit Secret Method.
As long as he refined the Second Nascent Soul through this secret method, it would be highly feasible to control this Black Turtle.
But the Second Nascent Soul was not something that could be refined just by refining it. Every living being only had one Nascent Soul, so it was naturally impossible to give birth to another Nascent Soul out of thin air.
Through this period of in-depth study of this Mysterious Female Transformation Spirit Secret Method, Zhang Ling discovered that there were basically only two ways to cultivate the Second Nascent Soul.
The first method was to split off a part of the divine soul, and it would only be possible to cultivate the Second Nascent Soul after a long period of nurturing with the split soul.
Zhang Ling had done this before when he refine the Corpse Bear into a Fiend clone but to refine the Second Nascent Soul, the split soul had to have at least 30% of the original soul's power.
This was not a simple matter, not to mention whether it would be successful.
It should be known that every living being's Nascent Soul was complete. For high-level cultivators, splitting off a small part of the Nascent Soul was not difficult.
But splitting off about 30% of the Nascent Soul would not only cause serious damage to one's own Nascent Soul, but even directly cause consciousness confusion, and possibly turn one into an idiot.
Some high-level cultivators used this similar method to control other people. They would make other cultivators split off half of their Nascent Soul and refine it into a Soul Banning tablet/sign. Holding the Soul Banning tablet/sign would allow them to control the life and death of others.
Some sect's inherited spirit beasts were also controlled in this way.
Even if they succeeded in splitting off half of their Nascent Soul, it might cause irreversible effects on their divine soul. The risk was too great, and doing so was tantamount to self-harm.
Therefore, Zhang Ling immediately eliminated this method. Even if he had Soul Nurturing Wood on him and had also cultivated Soul Refining cultivation techniques, and asked himself that his divine soul was much tougher than cultivators of the same rank, he would not dare to do so.
The risk of failure was not something he could bear.
The other method of cultivating the Second Nascent Soul was the main method of cultivating this secret technique. That was to invade other people's divine souls to cultivate.
Extracting other people's divine souls, erase their consciousness, and refining them into a soulless body, then assimilate them through secret methods and integrate one's own spiritual consciousness into the soul body was the way to cultivate this Mysterious Female Transformation Spirit Secret Method.
Once the spiritual consciousness was successfully integrated, the Second Nascent Soul would be refined. At that time, this soul body could be regarded as a vice Nascent Soul, possessing the same memory as the main Nascent Soul.
Of course, there were many dangers in this step. Assimilating other people's divine souls would also have an impact on one's own divine soul. However, this was much simpler and less dangerous than directly splitting one's own Nascent Soul.
At the same time, the vice Nascent Soul could also cultivate independently, which was equivalent to another self. Of course, to exert the full power of the vice Nascent Soul, one would have to find a suitable physical body to seize.
Now, the Black Turtle's physical body in the Two appearance gourd was the best physical body. That was why he collected turtle demon beast demon souls as soon as he came back.
Of course, there was also a special reason, which was that this Black Turtle belonged to a wild beast. Although the demon soul contained powerful soul power, its consciousness was confused by turbid qi.
If it were a demon beast demon soul, Zhang Ling would directly erase its consciousness, assimilate it with secret methods, and cultivate this secret technique.
But this Black Turtle demon soul was eroded by turbid qi. If he rashly assimilated it, his own Nascent Soul might also be eroded by turbid qi. Therefore, Zhang Ling collected other turtle demon souls, intending to use other demon souls to seize the Black Turtle, thereby controlling the Black Turtle.
But he was not sure whether he could succeed. After all, the icy cold spiritual power in the Black Turtle's body was extremely vast.
Looking at the Black Turtle demon soul constantly roaring in the Soul Nurturing Wood in front of him, Zhang Ling took a deep breath and waved his hand to take out the bronze ancient lamp.
A mass of vital blood integrated into it, and a faint green flame lit up. Zhang Ling's divine soul was immediately nourished, and his divine sense power instantly increased by more than doubled. He muttered a few incantations and uttered a word of break.
break!
A impact formed from divine sense power struck the Soul Nurturing Wood.
Instantly, the Black Turtle demon soul on it hissed, and its figure became flickering, disappearing into the Soul Nurturing Wood in a flash.
Zhang Ling snorted and put away the bronze ancient lamp and the three large and small Soul Nurturing Wood floating in front of him, and closed his eyes to rest.
Using the Soul Breaking Sound to impact the Black Turtle demon soul was naturally because the Black Turtle demon soul was too powerful and difficult to control. Every few days, he had to use this method to weaken the power of this demon soul to prevent it from breaking through the seal.
Of course, he could not directly destroy this demon.
Zhang Ling had long guessed that the biggest reason why the Black Turtle's physical body had not died might be because the demon soul had not been destroyed. Once this demon soul was destroyed, the Black Turtle might die immediately.
At that time, a Black Turtle corpse would not be of much use to him, and he could only strip the materials like ordinary demon beasts.
Only a living Black Turtle had the strength of a transforming demon beast.
After regulate breath and meditate for most of an hour, Zhang Ling's divine sense recovered. With a wave of his hand, another faint blue treasure pearl the size of a fist appeared in his hand.
As soon as this treasure appeared, a gust of cold wind blew beside him, and the entire room condense a layer of frost.
This treasure pearl was naturally the demon core in the Black Turtle's body. This was an eighth-order demon core, and the spiritual power contained in it was amazing. To exert the complete strength of the Black Turtle, this demon core was naturally also the most important thing.
Zhang Ling waved his hand again, and some bottles and jars and other items appeared beside him, containing various spiritual liquids.
He began to sacrifice refine this demon core with these spiritual liquids. The most important thing was to constantly scour this demon core with these spiritual liquids to expel the turbid qi on it.
At the same time, he thought to himself that if there was a way to directly dispel the turbid qi in the Black Turtle demon soul, he wouldn't have to be so troublesome.
But he had never heard of anyone being able to directly dispel the turbid qi in the demon soul of a wild beast. Otherwise, from ancient times to the present, the turbid qi in the wild region would not have been so rampant, occupied a large area of the flowing cloud Sea.
