The reason Zhang Ling is somewhat dispirited now is not because the second primordial spirit has not been successfully cultivated.
Seven or eight years ago, he erased the spiritual intelligence of the Azure Water Turtle demon soul and began to assimilate it using a secret method. It was completed half a year ago.
Although assimilating the Azure Water Turtle's demon soul over these years has also had some impact on his own primordial spirit.
After all, this is a seventh-order Azure Water Turtle's demon soul, equivalent to his cultivation level. Although the demon soul's spiritual intelligence was erased, assimilating other spiritual bodies is not easy.
A person's primordial spirit is inherently unique to them, and the same is true for demons and beasts.
To assimilate a demon soul of the same rank, there is a possibility of being counter-assimilated by the demon soul. It is not easy and involves many dangers.
This is the same as a demon refiner fusing with a demon soul. If the consciousness is not clear, one may become mentally confused and turn into a monster that only knows how to kill.
Therefore, the demon souls(妖魂: demon soul) fused by demon refiners are basically one rank lower than their own, precisely to prevent this danger.
During the assimilation process over these years, Zhang Ling sometimes felt that he was not a human but a turtle-like demon beast.
Although the spiritual intelligence of the Azure Water Turtle was erased, the divine soul and primordial spirit are the most mysterious. The demon soul still contains some memory fragments, and these fragments are the most dangerous things during the assimilation process.
Fortunately, his will is quite firm, and he also cultivates the Nine Yuan Refining Spirit Art, constantly wears soul-nurturing wood, and has the Ice Heart Pill previously refined from ice mulberry fruit, which can also provide good auxiliary effects.
It only took several years to complete the assimilation of the seventh-order demon soul.
Even if other cultivators have a firm will, assimilating a demon soul of the same rank, even if successful, will definitely take longer.
In fact, this Profound Female Transformation Spirit Art does not require demon beast demon souls to cultivate the second primordial spirit. The primordial spirit of other cultivators can also be used.
The reason Zhang Ling chose a turtle-like demon soul is naturally because he has a Black Turtle body comparable to a transformed demon beast in his hands. To match the Black Turtle, he chose a turtle-like demon beast.
After completely assimilating the Azure Water Turtle's demon soul, the second primordial spirit was successfully cultivated.
A few days ago, Zhang Ling controlled the second primordial spirit to seize the Black Turtle, directly occupying the Black Turtle body.
Even if it doesn't reach the true strength of a transformed demon beast, seizing a body comparable to a transformed demon beast is definitely a top-tier combat power.
But an hour ago, it failed.
Looking at the Black Turtle demon core in his hand, Zhang Ling's spiritual thought moved, and a gray light flashed on it, revealing the faint shadow of a small turtle.
The small turtle is emerald green all over, and its shape is blurred, as if a gust of wind could blow it away.
This turtle shadow is precisely his second primordial spirit.
This secondary primordial spirit can indeed perform the seizing technique, but, perhaps because the Black Turtle's(玄龟: Black Turtle) body is too powerful, or for some other reason, it experienced extreme rejection.
As soon as it entered the Black Turtle's(玄龟: Black Turtle) body, it was frozen by the massive icy spiritual power on its body.
Zhang Ling spent a great deal of effort to let this second primordial spirit break free, but it has suffered a lot of damage and is now very weak.
The small turtle shadow swayed and disappeared into his brow, merging into his body.
Without several months of recuperation, this second primordial spirit will not recover.
Sitting on the boulder, Zhang Ling is still pondering the reason for the failure.
Logically speaking, the Black Turtle's(玄龟: Black Turtle) demon soul has already been sealed in the Soul Banning Talisman. Although the body is not dead, there is no demon soul inside. In the end, it is just an empty shell. Logically speaking, seizing it should be easy.
Could it be because the Black Turtle's(玄龟: Black Turtle) strength is too strong, causing the body to react instinctively? Or is there another reason? He can't figure it out for a while.
After sitting quietly for a moment, he took out the iron piece that recorded the Profound Female Transformation Spirit secret method and began to study this secret method in detail.
Three months later, Zhang Ling came to a stone cave underground. A cave opening several dozen feet in size was opened in one side of the wall.
Standing next to the cave opening, outside is a large space, with the sound of rushing water constantly, and an underground pool appears in front of you.
The Black Turtle is lying in the pool, with most of its body submerged in the water. It looks as if a huge boulder has been added to the pool.
The entire pool is not large, and this beast occupies the entire space when lying in it.
This space was opened up as a secret space after returning to Fire Cloud Island, just to temporarily house this Black Turtle.
Looking at the Black Turtle in the pool, Zhang Ling turned into a ray of light and landed next to the Black Turtle's(玄龟: Black Turtle) head.
The beast's head alone is more than twenty feet in size. Although it is somewhat dull without the demon soul, it is still extremely ferocious.
With one hand pressed down, the water below churned, and huge black rock pillars rose around the pool.
With a flash, Zhang Ling stood on a rock pillar. After all the rock pillars were raised, each one was fifty to sixty feet high. With a light tap of his foot, dense spiritual patterns lit up on it, and many black light chains were condensed at the same time, one end wrapped around the rock and the other end wrapped around the Black Turtle's(玄龟: Black Turtle) body.
This is a set of Soul Sealing Formation, which is troublesome to set up and not suitable for moving. This formation is a powerful trapping formation. It seems to trap the Black Turtle, but this is the reason why this beast did not resist.
Setting up a formation here is just for insurance. If the Black Turtle truly unleashes its power, it cannot be trapped.
Zhang Ling waved his hand and took out the Soul Banning Talisman that sealed the Black Turtle's(玄龟: Black Turtle) demon soul.
Ordinary Soul Banning Talismans naturally do not need soul-nurturing wood. He used soul-nurturing wood to refine the Soul Banning Talisman to seal the demon soul of this beast, in order to prevent this beast's demon soul from dissipating.
The Black Turtle's(玄龟: Black Turtle) demon soul in the Soul Banning Talisman is much weaker than before.
After all, it has been separated from the body for more than ten years. Even if this beast's strength is comparable to a transformed demon beast, once the demon soul leaves the body without support, it will gradually dissipate.
Even so, this is still an eighth-order demon soul at the level of a transformed demon beast. Although this demon soul is much weaker now, it is still several times stronger than a seventh-order demon soul.
Since the Azure Water Turtle demon soul cultivated with the second primordial spirit before could not seize this beast, it is very likely because the Black Turtle's(玄龟: Black Turtle) demon soul has not been extinguished.
Of course, directly extinguishing the Black Turtle's(玄龟: Black Turtle) demon soul may cause the Black Turtle to die directly. A body that has lost its vitality is a dead thing and cannot be seized.
Basically, once the divine soul dissipates, the body will die.
Of course, the dead body can also be refined into a puppet. As long as the body is placed in a Yin Sha land, it may be refined into a demon corpse after a long time. Just like the previous Corpse Bear, it can be refined into a zombie body, and then controlled with a wisp of divine thought, it can also retain part of the Black Turtle's(玄龟: Black Turtle) strength.
This method is common among ghost cultivators, who refine evil things such as zombies.
But this will also take a lot of time. Even if it can be successful, refining this Black Turtle's(玄龟: Black Turtle) body, which is comparable to a transformed demon beast, into a demon corpse is estimated to take at least a hundred years, or even longer.
