The success of soul splitting was not a small incentive for Gu Yan, even in the eyes of the Nine Demon Emperor himself, the most critical step in cultivating the "Soul Clone Dafa" was also soul splitting.

And the reason why the Nine Demon Emperor was able to split the soul twice back then, and succeeded each time, was not just caused by good luck. Although the strength of the Nine Demon Emperor is not the top-notch among the Demon Realm Emperors, he is a rare soul cultivation genius in the Demon Realm.

According to the remnant soul Gu Yan of the Nine Shadow Demon Emperor, the Nine Shadows are the same as Gu Yan, and the soul power is much stronger than that of people of the same level, but there is no clear record of how powerful it is. Coupled with the study of the soul, he is very confident in the grasp of the success rate of soul splitting.

Therefore, from the very beginning, the Nine Demon Emperor has been refining two clones, not like Gu Yan, just to condense a soul clone with strong talent. So at this point, the two are also a little different.

In the blink of an eye, a few days had passed, and in these few days, Gu Yan had taken a Nine Transformation Divine Soul Grass and a Soul Lotus in a row. Under the nourishment of these two rare elixirs, the damage caused by the soul splitting to Gu Yan's soul was almost recovered.

Next, Gu Yan was ready to start refining the body of the clone, if he had obtained this secret technique before, Gu Yan might still be worried that he did not have the rare materials to refine the body of the puppet clone. But now it was different, from the storage ring of the Demon Slayer and the Second Hall Lord of the Demon Palace, Gu Yan had harvested a large number of rare refining materials.

Among these materials, there are many high-grade materials whose names Gu Yan knows, known as the hardest Taiyi Pure Gold, Red Wind Fire Copper, Glazed Blood Stone, Red Refining Thunder Sand, and Star Meteorite Iron······

Almost all of these materials are emperor-level refining materials that are difficult to find in Purple Saint Continent, and nearly half of them are materials for refining imperial soldiers. These ores, if they are taken out for auction, are enough to exchange for hundreds of millions of high-quality barren stones.

However, in Gu Yan's opinion, these have become auxiliary materials for refining clones at most, and as for the main materials for refining clones, they are also found by Gu Yan in the Demon Slayer Storage Ring, which is a piece of spirit wood.

At first, Gu Yan had not discovered the value of this wood, but because this wood was in the storage ring of Demon Annihilation, it was actually placed in a very high-grade spirit jade box by Demon Annihilation, and a bottle of Wood Source Spirit Liquid was placed in it, obviously to keep the wood attribute energy in the body of this spiritual wood from being lost.

Wood source spiritual liquid is an extremely high-level kind of natural spiritual liquid, generally only the spirit plant that has reached the level of heaven and earth spiritual objects can be produced, it can be described as a wood attribute treasure that can be encountered but not sought. However, it was used by the Demon Exterminator to prevent the loss of energy from this wood, and from this alone, it was enough to see the extraordinary nature of this piece of wood.

Then Gu Yan looked through a few ancient books inherited from Lingzun, which recorded many precious spiritual plants, ores, and pills on the Ancient Continent. In the end, under the inspection of Gu Yan, I finally found the origin of this spiritual wood.

In ancient times, there was such a sentence in the ancient continent: In ancient times, there was a sea and a sacred tree that dwelled on the ground, and the name was Fusang! Most people thought that this sentence was just a rumor, because no one had ever seen such a sacred tree, and after a long time, it was naturally regarded as an untrustworthy rumor by people.

However, Gu Yan knew that the "Fuso Divine Tree" really existed, because there were records about it in the ancient inheritance. In ancient times, there was a Shenmu Emperor, who practiced the wood attribute exercises to the peak, which can be described as unprecedented.

And the reason why this Shenmu Emperor has such ability is because he has obtained a branch of the Fuso Divine Tree, relying on this branch of the Divine Tree, and cultivating the wood attribute exercises is like divine help, so he has left such a good name as the Emperor of the Divine Tree in the world.

It's just that many of the historical secrets of the ancient period of the Desolate Continent were destroyed and forgotten in the ancient war between the human race and the beast race against the demons in the ancient period. Even now, a lot of information about the ancient period is not well known about the strength of the continent, but the ancient rocks with ancient inheritance are different.

Although Gu Yan didn't know why Demon Slayer actually had such a piece of divine wood, it was now cheaper Gu Yan. Fuso Divine Wood, although it is called a Divine Tree, is unable to produce spiritual wisdom for a lifetime, but it is able to gather the purest wood attribute energy in the world.

Moreover, the Fuso Divine Tree, the reason why it is called a Divine Tree, is not only because it can gather wood attribute energy. The Fuso Sacred Tree is also known as the Wood of Thunder Tribulation, which can absorb the energy of resisting the Heavenly Thunder Tribulation.

Therefore, since ancient times, Fusang Shenmu has been the treasure that all emperors dream of, because it is necessary to survive the Heavenly Thunder Tribulation to break the emperor and become holy, which is the nightmare of all the Great Emperors.

But according to the records of the ancient inheritance, the Shenmu Emperor did not enter the realm of the saint, and it seems that many of the secrets of the ancient continent also seem to be a little wrong, and now Gu Yan thinks about the words of Tuoba Hong at the beginning, the saint is not the top of the martial arts, it seems to be really a little credible.

Moreover, the Fuso Shenmu is so hard that even the imperial soldiers cannot cut it off. But the things in the world, all things are born and restrain each other, Fusang Divine Wood is a wood attribute treasure, the five elements are mutually reinforcing and restrained, fire is overcoming wood, and the top ten different fires can easily cut off or even destroy Fusang Divine Wood.

But no matter what, the fact is that this Fusang Divine Tree, which is enough to cause disputes on the mainland, fell into Gu Yan's hands, so and the size of this Fusang Divine Tree is enough to refine a complete clone.

Although Gu Yan's Red Demon Flame couldn't incinerate this Divine Wood at all, Gu Yan didn't care at all, he only needed to deal with it simply. Originally, the doppelganger body did not need special refining, and what really needed special refining was those auxiliary materials.

In the past, Gu Yan may not have been able to refine such high-grade materials as Taiyi Essence Gold and Star Meteorite Iron, but now it is different, there is geocentric magma under the ground of Sanfu City, and there is also the refining stone platform left by the Evil Wind Boy in order to refine the "Blood Tooth", and it is not a problem to refine these materials at all.

Thinking of this, Gu Yan said that he would do it, immediately got up, walked out of the cultivation room, and flew straight to the mine under Sanfu City. In the process of descending to the cave, Gu Yan found that at the bottom of Sanfu City, there were indeed many spirit level desolate beasts.

In the past, there were few barren trees around Sanfu Castle, but now, nourished by the rich vitality, it is like a lush barren forest, and many trees are even hundreds of meters high. But Gu Yan only felt it slightly, and then landed directly on the periphery of the cave.

Playing a spell, the formation outside the cave was opened by Gu Yan, and suddenly a more dense heaven and earth vitality surged out, Gu Yan did not hesitate, dodged into the cave, and then closed the formation.

Entering the cave, Gu Yan found that Jin Ling had fallen into a deep sleep again, but this was a good thing. Because such a deep sleep is actually the bloodline of the Titan God Ape in the awakening body. Immediately, Gu Yan looked at Jin Ling, and went straight into the depths of the mine, and a scorching air flow suddenly scorched Gu Yan.

But Gu Yan didn't care about these heat currents at all, and the Gu Yan who cultivated the "Great Five Elements Technique", the energy within the attributes of the five elements was a great supplement. Looking at the black stone platform where the blood teeth were placed, Gu Yan walked into the stone platform and injected a demonic qi into it, and suddenly, the stone platform immediately sank.

Slowly falling, staying in the magma at the center of the earth, the stone platform also turned from black to crimson, and the surrounding air was deformed by the sudden rise in temperature. Gu Yan did not hesitate, and manipulated the Fusang Divine Wood Divine Mind in the storage ring into the groove on the top of the stone platform.

The temperature in the groove was terrifying, and even the materials for refining the Imperial Soldier could melt quickly, but the Fuso Divine Wood did not change in the slightest.

"It is worthy of being a divine tree, in the face of such a temperature, there is no change, so in the future, the doppelganger of Ben Shao will not be even more awesome than the demon body that sacrifices to them. He sighed, and then threw dozens of rare ores into the stone trough in a row.

Shen Nian slowly manipulated these rare ores, constantly tumbling in the stone trough, and those ores were melting and merging with each other at a speed visible to the naked eye.

While controlling the smelting of those ores, Gu Yan sank the Fusang Divine Wood into the magma of the earth's core, and only by raising the temperature of the Fusang Divine Wood to the extreme can the smelted molten metal be successfully fused and refined into a whole to the greatest extent.

About half an hour later, all kinds of rare ores put into the ancient rock in the stone trough were smelted into molten metal, and they were also manipulated by the ancient rock and fused with each other.

Although Gu Yan knew that such chaotic smelting in everything would make the true value of many rare materials not be used to the fullest, he didn't care. As long as there is Fuso Shenmu, the doppelganger can almost reach the point of immortality.

Taking a deep breath, Gu Yan prepared to begin fusing the molten metal with the Fuso Divine Wood to refine it into a puppet clone. Slowly moving the Fusang Divine Tree out of the magma at the center of the earth, the Fusang Divine Tree at this time had already turned red, but there was no sign of anxiety.

"Success in one fell swoop, my perfect doppelganger. He said a word silently in his heart, and then he wholeheartedly manipulated the molten metal to cover the outside of the Fuso Sacred Tree, and on the other hand, the limbs and head were also smelted from the molten metal and attached to the Fuso Sacred Tree.

Although Gu Yan had never seen the refining battle puppet with his own eyes, in the few days he had recovered his soul power, he had seen a lot of knowledge about refining weapons in this area. Some of these tips can be regarded as having mastered a lot, and his requirements for doppelganger refining are not high.

Gradually, with the control of Gu Yan, the Fuso Divine Wood and the molten metal finally fused together, and the next step was to perfect the clone puppet. Because although the doppelganger puppet is made of metal, its flexibility is not inferior to that of humans, and even some top refining masters, the metal puppets refined are no different from real people.

The most critical step in perfecting the metal golem is the joints of the limbs, because the metal refining golem is not like the human body, it is naturally as flexible. The limbs of the metal puppet had to be refined by the refiner himself.

However, this is not difficult, the so-called imitation is just that, the molten metal can solidify the shape of human bones, and every joint only needs to imitate the structure of the human skeleton. This is not a problem for Gu Yan at all, because Gu Yan was very interested in the structure of the human body in the previous life, and he read a lot of medical books on this area, and he is very familiar with the structure of the human skeleton.

Soon, under Gu Yan's careful refining, a metal puppet similar to his body was successfully refined, although it looked a little rough in many places, but it was also considered to be seven points of godlikeness, such a result, Gu Yan was already very satisfied, after all, refining weapons was not his strong point.
