In the bottom of the Nine Shadows Sea, there is darkness, without any light, eternal and eternal, and at this moment, in the large array arranged by the Yin and the Netherworld, the two balls are covered by the water of Xuanzhong, but Lei Yu is aware that they are constantly merging.

The gap between the two spheres of light is becoming less and less, and the number of conflicts is decreasing, and sooner or later they will merge together.

Time passed day by day, and on the first day, the two light balls did not make much progress, and the conflicts continued, all kinds of forces were mixed together, and all kinds of roars were endless. If it weren't for the neutralization of the Xuanzhong Water, I'm afraid the two lumps of materials would have been destroyed long ago.

On the third day, there was some progress between the two balls of light, and the force of the conflict was no longer as violent as before, and there were some signs of fusion.

On the fifth day, the balls of the auxiliary materials began to merge into the balls of the six main materials, and the forces of the two sides began to level out.

On the sixth day, the ball of the auxiliary material was completely integrated into the ball of the six main materials, and it became one and evolved into a new material, and this material was still increasing, which made Lei Yu feel excited, because this kind of power was the main material for refining the Abyss Gun.

The fusion of the two spheres went smoothly and there were no major problems. Of course, during this period, Lei Yu was also engrossed, and Shen Nian always paid attention to the fusion of the two spheres.

Just in case, Lei Yu was always ready, as long as the two balls had an accident, he would immediately stop them and save the crisis.

"Is the fusion finally complete?"

On the seventh day, Lei Yu opened his eyes and looked at the two balls that were covered by the black Xuanzhong water, and there was a trace of excitement in his eyes.

He had waited a lot of time for this day, and today it was finally done.

"Open!"

Lei Yulang shouted loudly, like thunder. In an instant, the large array arranged by the Yin and the Netherworld shook, and the thick Xuanzhong water suddenly dispersed, revealing the scenery inside.

The two balls were gone, replaced by a dark one. It is a foot high, round, and the whole body is black, and there is no gap in sight, which looks quite ugly.

However, seeing this incomparably black ball, Lei Yu's face couldn't help but show a look of joy, this is the result of the fusion of the two masses of materials, the essence of the two masses of materials, and it is also a necessary thing for refining the Abyss Spear.

This black ball is very peculiar, it does not have the appearance of the original material, it is a material that has never appeared. It is neither gold nor stone, I don't know what material it is, but it contains an astonishing amount of power, and this amount of power is the necessary amount of power for Lei Yu to refine the Abyss Spear.

This material is very extraordinary, and in the "Nine Shades of Yellow Springs", the refining method of this material is recorded. Without this material, even if the six main materials and auxiliary materials were collected, it would be impossible to refine the Abyss Spear.

Now, Lei Yu has been tempered thousands of times and refined this material with the water of Xuanzhong, and it is time to start refining the Abyss Spear.

Lei Yu's eyes flickered, and the longing in his eyes was indescribable. The Shen Yuan Spear was a thunder soldier held by the Nine Shadows Emperor back then, sweeping through the Liuhe Eight Desolations, invincible, and Lei Yu, as the descendant of the Hell Demon Sect, naturally also wanted the Shen Yuan Gun.

"Boy, you're doing a good job, let's start refining the Abyss Spear now!"

The Yin Yin voice said.

He has also been paying attention to Lei Yu's refining process, although he is not in the big array, but his divine thoughts have been staring at Lei Yu's body, so he is very clear about Lei Yu's every move, seeing that the special material has been refined, it is impossible to say that he is not excited.

Lei Yu nodded fiercely, his eyes looking at the black ball. In his eyes, the black ball has become a treasure, and all hope is pinned on the ball.

Lei Yu clasped his hands to his chest and made a strange gesture with his hands. At the same time, he closed his eyes again, opened his mouth and shouted: "Shen Yuan Heaven and Earth, Condensation!"

This voice seems to represent the will of heaven and earth, as soon as it appears, the wind and clouds surge in the great array, and the water of Xuanzhong surges, boundless, and the waves are shocking, as if they are about to sweep through the ages, and there is a mysterious aura contained in it.

Lei Yu's hands began to move, and every posture seemed to contain a kind of heaven and earth reason, and every move was in line with the operation of the Heavenly Dao, which was extremely mysterious.

This is the refining technique of refining the Shen Yuan Gun that Lei Yu learned in "Nine Shades of Yellow Springs", called the "Shen Yuan" technique. The Nine Shadows Emperor was worried that the method of refining the Abyss Spear would be lost, and explained in detail how to refine the Abyss Spear, so Lei Yu was able to perform this refining technique so easily.

With the wave of Lei Yu's hands, the black ball began to rotate, and a black smoke spread out from the ball and floated into the air. At the same time, a slight foul odor emanated from the smoke.

This stench is not very strong, but it can cause the refiner's negative emotions and affect the refiner's mind, resulting in refining failure.

The Nine Shadows Emperor focused on this smell in the "Nine Shades Yellow Spring Jue", these smells are not ordinary odors, but the impurities contained in this black material, and only by using the "Shen Yuan Technique" to remove these impurities from it, the quality of the Shen Yuan Gun can be guaranteed.

Although these auxiliary materials and the six main materials have been refined, the new materials formed by fusing together have formed another impurity, which is not the impurities contained in the ordinary materials themselves, but the products of the inability to fuse these auxiliary materials and the six main materials.

There aren't many of these things, but they have the potential to have an impact on the quality of the Abyss Gun. In order to ensure the quality of the Abyss Gun, these things must be removed.

Lei Yu's mind was the same, and the "Shen Yuan Technique" became more and more proficient. As he cast it, he could feel his connection to the black orb grow closer and closer, and he had a feeling as if he had become the black orb, in charge of everything, and he knew everything in the black orb.

Lei Yu finally understood how terrifying the "Abyss Technique" was, it was completely created for the Abyss Gun, and it controlled everything about the Abyss Gun. How powerful the Abyss Spear was refined in this way, he himself couldn't help but look forward to it.

"Boom!"

Lei Yu stretched out his right hand and pointed forward suddenly, the black ball shook suddenly, and a thick black smoke emanated from the ball, and then I saw that the black ball had changed slightly, and the rich black became a little lighter.

This is the impurities of this material have been completely removed, without the slightest retention, and the sphere has become a completely pure existence at this moment, and nothing can affect this black sphere.

"Break the Nine Shadows, Condense the Divine Spear!"

Lei Yu shot again, and suddenly shouted, the sound was like a flood of bells, and in a moment, the black ball was suddenly straightened and turned into a long black bridge about ten zhang long, lying in front of Lei Yu.

"Huh!"

Suddenly, bursts of powerful Nine Shadows Yellow Spring Thunder Qi gathered in Lei Yu's right hand, and suddenly, Lei Yu stretched out his right hand and transformed into a huge muddy yellow hand.

This big hand is huge, more than a foot long, as if to pick the clouds and take the moon, and between the waves, there is a terrifying momentum that permeates the surroundings.

Bursts of waves surged, and the water of Xuanzhong felt a little unsupportable in the face of this big hand, and they gave way one after another. In an instant, this big yellow hand walked towards the long black bridge that was more than ten zhang long.

"Bang!"

The big yellow hand finally held the long bridge of more than ten zhang, and then this big hand lifted the black long bridge, as if it was going to lift the heavens and the earth, full of infinite power.

"Nine Shadow Marksmanship, Break Heaven and Earth!"

Lei Yu let out a loud shout, controlling the big hand and starting to dance the black long bridge, and the long bridge didn't even react at all, as if it was naturally compatible with the big hand.

That's right, it's a natural match, and the black long bridge is danced by big hands, like a straight spear, dancing the heavens and the earth, breaking everything.

"Kill!"

Lei Yu's eyes were bloodshot, and with his big yellow hand as his right hand, he danced the black spear, setting off waves in this space.

The black spear turned into a huge spear, and in this huge hand changed all kinds of moves, or stab, or sweep, or rush, there is an indescribable meaning.

Lei Yu closed his eyes, his heart moved with the gun, controlling the big hand, and there was a villain in the sea of knowledge dancing a small spear to his heart's content. If you look closely, you can even see that this villain is a miniature version of Lei Yu, and that spear is the black spear.

Not only outside the body, but even in Lei Yu's heart, there is a battle going on.

This is the Nine Shadows Gun specially prepared by the Nine Shadows Emperor for the Shen Abyss Gun, if the Shen Abyss Gun wants to take shape, the only way to continue to use the "Nine Shadows Marksmanship", in the process of dancing, the black long bridge is condensed again, and finally turned into the Shen Yuan Gun.

This is the refining method of the Abyss Spear, which does not require continuous tempering of materials like ordinary refiners refining thunder soldiers, but retains 100% of the essence of black materials in the most simple way, which is an extremely peculiar innovation.

Perhaps, only the Nine Shadows Great Emperor on the entire Thunder Continent could come up with such a creative and unique refining method.

Lei Yu controlled the big hand to wave the black long bridge, and the moves recorded in the "Nine Shadows Marksmanship" continued to emerge in the sea of knowledge, and every time he stabbed out, some changes would occur on the black spear, becoming more condensed and stronger.

A heavy aura emanated from the long bridge, and the long bridge became more and more quaint, and gradually there was a sharp edge, as if it was about to pierce the sky and sweep the sky.

Time passed little by little, Lei Yu was immersed in the "Nine Ghost Marksmanship" and comprehended the mystery contained in the "Nine Shadows Marksmanship".

This is the marksmanship created by the Nine Shadows Emperor, the mystery is profound, and it matches the Shen Yuan Gun, if it is comprehended, it will only be good for Lei Yu and there will be no harm. When the Abyss Spear is refined in the future, the combination of the two will definitely improve the combat power qualitatively.

Lei Yu forgot to dance the black spear, his eyes were closed, and his whole body exuded a kind of self-sacrificing momentum. In this moment, he forgot about himself, and only the spear in his eyes was in his eyes.

The black long bridge began to shrink gradually, the bridge body became more condensed, and it contained the essence of the "Nine Ghost Marksmanship", and the entire bridge body was like a straight gun body, pointing straight to the sky. And at the end of the long black bridge, a white light emerged, filled with an endless and fierce aura.

This is where the tip of the Shen Yuan Gun is, with a gun in hand, sweeping through the Liuhe Eight Desolations, the prototype of the Shen Yuan Gun has finally been formed.
