The two balls are not pretty, one is gray, the other is shining with various colors, and the volume of the two is also very different.

Lei Yu looked at the two round balls with satisfaction, and there was a trace of curvature at the corner of his mouth. Even though his thunder power and divine thoughts were almost exhausted during the sacrificial refining process, seeing such results, he felt that everything was worth it.

With a pat on his waist, a yellow vial appeared in Lei Yu's hand. This vial looks very ordinary, without much luster, but Lei Yu values it very much, because this bottle contains Lei Yuan liquid.

That's right, Lei Yu is going to use the Thunder Source Liquid, and refining the Shen Yuan Gun will inevitably require a lot of thunder power and divine thoughts, and Lei Yuandan alone can't replenish it at all. At this time, only Lei Yuan Liquid can play some role.

"Bang!"

The mouth of the bottle is opened, and a wisp of fragrance comes out of the jade bottle, like a hundred flowers in full bloom, and the fragrance of the flowers is overflowing, which is very comfortable.

A pure thunder force permeated this space, Lei Yu only smelled it and felt that his body seemed to be a little relaxed, and the speed of thunder power was much faster, and vaguely, his thunder power actually improved somewhat.

This is the thunder source liquid, the creation of heaven and earth, it is the spiritual liquid honed from the thunder source stone, full of many magical effects, just a little bit of the fragrance of the thunder source liquid has such a powerful effect, you can imagine how rebellious the thunder source liquid is, even the cultivators of the thunder infancy can not let go, and the desire for a drop of thunder source liquid is priceless.

"It's up to you this time!"

Lei Yu muttered to himself, and with a tap of his right hand, a drop of Thunder Source Liquid flew out of the jade bottle and entered Lei Yu's mouth.

A faint fragrance seeped out of the thunder source liquid, and then a powerful force erupted from the thunder source liquid, filling his body. In an instant, Lei Yu Yuanbei's somewhat depleted Heavenly ** Aperture and Tianyang Acupoint Acupoint were filled again, and there was continuous thunder surging in his body, supporting his consumption.

At this moment, he felt as if his body was about to explode, filled with endless power, and vaguely, the ninth ** aperture of the Tianyang acupoint had a tingling feeling, and it seemed that it was possible to break through at any time and reach the ninth order of the Lei Gang period.

If it weren't for the strong suppression of Lei Yu, the powerful thunder power gushing out of the thunder source liquid would really have broken the ninth ** aperture.

Moreover, not only that, Lei Yuanye also had a great effect on his divine thoughts. Under the influence of Lei Yuanye, his divine thoughts vaguely had a full feeling, and it seemed that he could be promoted again at any time, reaching the strength of the true Thunder Dan stage divine thoughts.

For this change, Lei Yu was naturally overjoyed, during this period of time to refine the materials, he deeply understood the importance of the Dao Divine Thoughts. If he didn't have the support of a strong divine thought, he wouldn't have been able to refine these materials.

Blinding golden light flashed out from Lei Yu's body, he was like a golden armor god, the golden light shone in all directions, and the bottom of the dark Nine Shadows Sea actually had a feeling of welcoming light again.

"The water of the Xuan Chong merges into one!"

The thunder power in his body is endless, and Lei Yu naturally will not let go of such an opportunity, and with a loud shout, he will completely fuse these two round balls together.

The sound spread, sweeping in all directions at the bottom of the Nine Shadows Sea, like a flood bell and a great lu, shocking people's hearts.

If someone was nearby at the moment, they might be stunned by Lei Yu's loud shout. However, even so, outside of this space, there were some smaller ghost beasts that fainted.

Of course, Lei Yu didn't know about this situation. Moreover, even if he knew about these things, I am afraid that he would just smile and pass.

With his shout, two huge balls began to surge, exuding a stream of aura, and the surrounding Xuanzhong water was affected somewhat, and the waves were turbulent, wanting to break through this space and merge with the Nine Shadows Sea outside.

The terrifying giant Lang rolled the heavens and the earth, wanting to tear everything up, this space was shaking, but at this moment, Lei Yu was widening his eyes, and all his attention was focused on the two balls, as if in his eyes, only these two balls existed.

"Boom!"

The two spheres traveled slowly, and each step would cause a great concussion, and a strong repulsive force was generated from it, preventing the two spheres from converging.

This is determined by the quality of the two materials themselves, and the gap between the auxiliary materials and the six main materials is too great, and it takes a lot of effort to integrate the two into one.

Lei Yu frowned, but he didn't say anything, the fusion of the two light balls was indeed very difficult, but it was not impossible to complete.

His thoughts scattered, propelling the two balls forward, and at the same time, he waved his hands, and a cloud of yellow light obscured them. Then, I saw him throw a punch with both hands and hit the two balls.

A huge amount of force gushed out, Lei Yu now has the help of Lei Yuanye, and he is not afraid of the consumption of thunder power at all, so the force of these two punches is also very large, as soon as it hits the two balls, the originally slow speed has risen a lot in a moment, and the distance between the two balls is also a lot closer.

Seeing this, Lei Yu showed a look of joy on his face, and made persistent efforts, the two fists were like two pushers, constantly bombarding the two balls, so that the distance between the two balls was getting closer and closer, and finally collided together after reaching the peak.

"Boom!"

The roar sounded, and this space shook, and the surrounding Nine Shades of Sea water continued to suppress this space, as if it could submerge this space at any time and completely sink to the bottom of the Nine Shades Sea.

However, Yin Yin is a powerhouse of the Immortal Thunder Stage, and with a wave of his right hand, all fluctuations have stopped, protecting this space.

"This kid has gone a little too far!"

Outside of this space, Yin Ming was also concerned about Lei Yu's situation, and there were tic-tac-toe wrinkles on his forehead, obviously worried about Lei Yu.

And all around him, the corpses of all kinds of ghost beasts floated around him, large and small, different, and he killed all the ghost beasts within a radius of hundreds of miles around, just because he didn't want these ghost beasts to disturb Lei Yu refining the Abyss Spear.

In the middle of the formation, some beads of sweat appeared on Lei Yu's forehead, and his face was a little pale. The collision just now was so intense that he couldn't hold it anymore. Fortunately, the effect of the thunder source liquid is extremely ungodly, and it has delivered the most critical thunder power to him at a critical moment, otherwise, the consequences will be unpredictable.

"Give me fusion!"

Lei Yu roared, and the divine thought split into two, controlling the fusion of two huge balls.

Dazzling white light burst out from the junction of the two spheres, and the monstrous power swept all around, setting off a monstrous giant Lang. In an instant, in this space, it seemed that the end of the world had arrived, and the wind and clouds were crazy and immeasurable.

Lei Yu's face became more and more pale, the collision of the two balls was too intense, far beyond his imagination, all kinds of forces collided together, amazing, even a cultivator in the Lei Dan stage did not dare to take advantage of it.

"The water of the Xuanzhong, smelted into one!"

Lei Yu struck again, swiped with both hands, and huge energy fluctuations erupted from his body, mobilizing the surrounding Xuanzhong water to rush towards the two round balls.

"Whoa!"

The black water was surging, the sky was endless, and as soon as it surged in, the two balls of light were instantly submerged by the black Xuanzhong water, and there was not the slightest trace of it.

However, Lei Yu's face did not change color in the slightest. If you want to look at it carefully, you can even see a trace of arc emerging from the corners of Lei Yu's mouth.

The fusion of the two light balls is very difficult, and at this time, the purpose of adding the Xuanzhong Water is to make the fusion of the two light balls easier. In other words, at this time, the water of Xuanzhong is equivalent to the existence of a fusion agent.

Lei Yu's divine mind has been paying attention to the state of the two balls, with the addition of a large amount of Xuanzhong Water, the speed of the fusion of the two balls has been significantly improved, and the conflict between the two sides is also a little less, and it is no longer as intense as before.

This shows that the auxiliary materials and the main materials are no longer as conflicting as before, and it is only a matter of time before they converge.

Lei Yu secretly breathed a sigh of relief, as long as he fused the auxiliary materials with the six main materials, he could refine the Abyss Spear according to the idea in his heart.

"The next thing is to wait for the degree of integration of the main and auxiliary materials!"

Lei Yu looked at the two balls that were submerged and said lightly.

His face was a little pale, and the golden light on his body was a little weaker. Even with the replenishment of Thunder Source Liquid, his thunder power consumption speed is still too fast, and some of them can't make ends meet, and if he continues like this, his thunder power will be exhausted sooner or later.

However, although there were some twists and turns in the fusion of the two spheres, they were successfully fused together in the end. Now it is impossible for him to intervene in the fusion of the two, because once the fusion occurs, it is impossible to stop, and he cannot interfere with the progress of the fusion.

This is also the special feature of the water refining method, unlike the fire refining method, which can freely control the fusion of various materials. Refiners who use the Water Refining Method only need to guide the fusion at the beginning, and the rest of the matter belongs to the materials themselves, as they will merge on their own and do not need to intervene.

This method can ensure the thorough use of the material as much as possible, unlike the fire refining method, which will lose the quality of the material. Of course, there are advantages and disadvantages, because the speed of fusion cannot be controlled, the refiner himself does not know when the fusion of the Dao materials will end.

The reason why Lei Yu is refining the Shen Yuan Spear now is because he wants to improve his strength before going to Beiming, and the other is because there is a precedent.

At the beginning, when the Nine Shadows Great Emperor was refining the Shen Yuan Spear, it only took a few days to fuse the materials, so Lei Yu was so relieved and bold to let the two groups of materials fuse independently.

Otherwise, it will take tens or hundreds of years to fuse a material, so what kind of thunder soldiers will be refined.

Lei Yu sat aside with confidence and boldness, waiting for the fusion of the two masses of materials, and at the same time to recover his own thunder power, although he had Lei Yuan liquid as a supplement, he was still a little uneasy, after all, no one knew how much thunder power was needed to refine the Shen Yuan Spear.
