After returning to his cave in the Black Dragon Tower, Fang Kun pondered for a long time before entering the golden bead.

When the four girls saw Fang Kun appear, they immediately surrounded him, chatted with the four girls for more than an hour, and instructed a few people carefully before he left.

In the bracelet space, the earth core molten flame was still suspended there, burning quietly, but in the surrounding space, there was a trace of cold and cold aura, and Fang Kun's face showed a hint of surprise, but he was quickly relieved.

Presumably, this kind of icy aura is precisely because the core melt has devoured the Nine Mysterious Ice Liquid, and in the process of evolution, a trace of the same aura has been born, so it will be like this.

After carefully sensing it, Fang Kun left helplessly.

After returning to the golden bead, Fang Kun sat cross-legged in a dimly lit space, closed his eyes, and began to carefully digest the old devil's memory, to be exact, he was contemplating the other party's method of cultivating the doppelganger technique.

According to the results of his previous investigation, if he can successfully cultivate that kind of clone technique, then he can leave a clone, in addition to preventing accidents and retaining a trace of vitality, he can also let the clone cultivate on its own!

The most attractive thing to Fang Kun is the last point, because of the particularity of the exercises he has cultivated, he has devoured too many divine souls, so he has gained a lot of memories and various avenue insights, but he doesn't have much time to digest it well, if he can cultivate the composition technique, he can let his clone stay in the space treasures all the time, meditate on those devoured divine souls, and completely refine them into his own perceptions, so that he will save a lot of time!

Time passed little by little, and it wasn't until the evening of the next day that Fang Kun suddenly opened his eyes, and a trace of excitement appeared, and then, with a movement of his mind, a black ring appeared in front of him.

According to the information he got from the old devil's memory, if he wants to cultivate the doppelganger technique, in addition to the strength of his own divine soul and a huge energy supply, he also needs some natural treasures, such as demon soul stones and other treasures, and of course, high-grade elixirs that can repair and nourish divine souls.

Fortunately, the only thing Fang Kun lacked in these conditions was the treasures necessary for cultivating the doppelganger technique, such as the Demon Soul Stone, and these treasures, although they were rare, among the space treasures of the old devil, he had just prepared one for himself, and the purpose was naturally to prevent his own doppelganger or the fall of the main body, so that he could quickly cultivate a new doppelganger!

This just saved Fang Kun trouble, it is estimated that the old devil never thought that the treasures he had worked so hard to collect would become other people's wedding dresses.

As for the elixir to repair the soul, the old devil prepared a six-pin elixir for himself- Nine Souls Melting Blood Pill, although this kind of elixir Fang Kun has not seen, but after probably understanding the memory of the old devil, he knows that although this Nine Souls Melting Blood Pill is expensive as a six-grade pill, it is actually not very clever, its essence is to burn his own natal essence blood, in order to repair the soul, compared to the pills in his hand, although the grade is higher, but the effect is really not flattering, after all, burning the natal essence blood, the same needs to be restored, but the essence blood is restored, compared to the soul, it is much simpler, only need to take some genius treasures, or pills, but the premise is that the natal essence blood can not be lost too much！

Looking at a fist-sized piece of Demon Soul Stone in front of him, Fang Kun frowned slightly.

This Demon Soul Stone, he also saw it for the first time, its effect is actually similar to that of the Soul Nourishing Jade, it has the effect of nourishing the Divine Soul, but it is much more valuable than the Soul Nourishing Jade, because it can send a Divine Soul, that is to say, if you cultivate a part of your Divine Soul Origin in it, you can make it continue to grow.

And the first step in cultivating the doppelganger technique is to separate a part of your divine soul and cultivate it in the demon soul stone, and when it is strong enough, you can use it to cultivate the doppelganger technique!

And the reason why this is done is also because ordinary people dare not forcibly separate and tear apart the divine soul, on the one hand, most people's divine souls, no matter how powerful they are, it is impossible to separate too much at one time, Lin On the one hand, the divine soul is the foundation of life after all, once it loses too much, it will inevitably be hit hard, and even fall, and it will inevitably affect the cultivation!

This point, in Fang Kun's place, naturally does not exist, his divine soul is already much stronger than ordinary monks, it is no exaggeration to say, compared with monks of the same level, his divine soul is at least ten times stronger, even compared to the distraction period monks, his divine soul is much stronger, but it is just that it has not condensed the original spirit!

But even so, Fang Kun still planned to follow the method in the old devil's memory, and try it first, after all, it was the first time he cultivated this doppelganger technique, and the divine soul was too important, even if his divine soul was strong, he didn't dare to be careless in the slightest, so as not to be hit hard!

After breathing for a moment, Fang Kun slowly closed his eyes, and then the next moment, his brows furrowed tightly, his face turned pale in an instant, and he even showed a look of pain, his face was almost distorted.

In his mind, the cloud of divine soul mist that had originally gathered together was forcibly divided into a part by him, and it should have been only half a percent, that is, five percent, but even so, the pain of soul tearing was still unbearable for Fang Kun!

You must know that these are his Divine Soul Origins, and as for the Divine Soul Origins of the more than sixty Distraction Stage cultivators who were devoured by him before, because they have not been completely refined by him, he does not dare to use them in the slightest!

After a while, a trace of invisible air flowed out from Fang Kun's eyebrows, directly submerging into the Demon Soul Stone in front of him.

Without the slightest hesitation, Fang Kun directly swallowed a Divine Cultivation Pill.

A medium-grade Divine Pill turned into a pure and gentle mysterious energy, directly following the meridians in his body, flowing into his mind, and immediately, an extremely comfortable feeling hit, making Fang Kun can't help but let out a groan.

As time passed, the pale color on his face gradually disappeared, and the wound that his soul was torn apart gradually disappeared in his mind.

An hour later, feeling that the medicinal power of the Divine Cultivation Pill had completely disappeared, Fang Kun opened his eyes, but then he frowned.

Although the injury in his mind disappeared, he could clearly sense a trace of discomfort, although it was extremely slight, but after all, it was a soul injury, he still would not ignore it, and after exploring the situation in the demon soul stone, he slowly breathed a sigh of relief, and his mind moved, and his body disappeared in place.

In another dimly lit enclosed space, more than thirty spiritual veins were piled up together, imprisoned by several sixth-level magic circles, so that the spiritual energy would not overflow.

Fang Kun's figure appeared on a spiritual vein, and as soon as his mind moved, he directly carved the formation runes on the spiritual veins, and a moment later, a huge formation enchantment appeared, enveloping all the spiritual veins, and the place where he stood was the formation eye, and all the spiritual energy gathered here, almost condensed into a liquid existence.

But even so, Fang Kun was still not very satisfied, his mind moved, ten bottles of spiritual liquid appeared in the palm of his hand, and after pouring ten bottles of spiritual liquid into a huge jade bottle, he put the demon soul stone into it, and then, put the jade bottle in the position where he opened his eyes.

After observing for a moment, a smile appeared on Fang Kun's face, and then his figure disappeared in place.

If someone saw Fang Kun using the spirit veins and spiritual liquid so extravagantly, they would probably be speechless, but for Fang Kun at this time, these spirit veins really didn't have much effect on him, so he would use them to cultivate the wisp of divine soul origin in the Demon Soul Stone.

After all, the aura contained in the spiritual veins is the most original heaven and earth aura, which can nourish the divine soul, and because the divine soul elixir is rare, ordinary monks, once the divine soul is injured, they will slowly recover the wounds of the divine soul by absorbing the spiritual energy in the spiritual stone.

It's just that this method came too slowly, after all, although the aura of heaven and earth can repair the injuries of the divine soul, the trace of energy that can repair the divine soul contained in it is too thin, so it takes too long to repair the divine soul with this method!

For example, according to what the old devil said in his memory, after separating the divine soul, he would have to place the demon soul stone on the spiritual vein to cultivate, and it would take at least a few years until it could be comparable to the divine soul of an ordinary monk before he could start cultivating the doppelganger technique, such a long time, Fang Kun was obviously unacceptable!

Therefore, he did not hesitate to spend more than thirty spiritual veins to nourish his own wisp of soul.
