The water of Xuanzhong was heavy, and there were tens of millions of heavy surges, covering the sky and the sun, gradually filling this space, and the black pressure was very amazing, as if it was a black cloud pressing on the top, so that Lei Yu's heart was full of heaviness.

This is the essence of the Sea of Nine Shadows, every drop is heavier than a thousand pounds, so much mystical water enters this radius of a hundred zhang and weighs more than the weight of dozens of mountains. If an ordinary cultivator had entered it, he would have been crushed to death by these mystical waters.

However, Lei Yu's own body is extremely strong, comparable to a mid-grade Gang's soldiers, and with the help of the Water Avoiding Pill, these Xuanzhong waters did not put too much pressure on him, after all, Xuanzhong Water could not escape the category of water no matter how anything.

The Water Avoidance Pill given to him by Yin Ming is not comparable to an ordinary Water Avoidance Pill, even spiritual water like Xuanzhong Water can be avoided, so he can move in this space so easily, and he can even use Xuanzhong Water to refine the Abyss Spear.

"It's so heavy water!"

Lei Yu stood in a corner of this space, reaching out to grab a drop of water, and after a moment, his brow furrowed slightly.

The weight of the Xuanzhong Water was somewhat unexpected to him, it was heavier than the refined iron, no wonder it was called the Xuanzhong Water, and there was indeed a certain amount of truth.

Moreover, this Xuanzhong Water also contained a strong corrosiveness, as soon as his hands touched the Xuanzhong Water, a trace of white smoke immediately rose, and there was also a trace of black marks in his palm.

Lei Yu didn't care too much about this mark, with his current physical strength, he didn't need to worry about this amount of corrosive power. Instead, a smile appeared on his face, this Xuanzhong Water had such a great effect that it was only good for refining the Abyss Spear, and there was no harm.

"Huh!"

With a wave of Lei Yu's big hand, the mouth of the space bag hanging on his waist opened, and in an instant, a five-colored light flew out and fell into this mysterious water.

In an instant, white smoke rolled and the water of Xuanzhong surged, drowning out the light.

These are some ordinary auxiliary materials, naturally they can't withstand the power of this Xuanzhong water, as soon as they come into contact, there is a tendency to melt, and even some auxiliary materials are directly crushed into pieces by the Xuanzhong water, and they no longer exist.

The black water of Xuanzhong came like a tide, even though there were many of these auxiliary materials, but the quality was not good, when facing these Xuanzhong water, they were defeated in an instant, and the surface of many materials had turned into a liquid form.

"It melted a little too fast. ”

Lei Yu muttered to himself, a little nervous in his heart.

This is the first time he has refined a weapon, and he is still using the method of water refining, it is impossible not to be nervous, and this time he is refining the abyss spear used by the Nine Shadows Emperor at the beginning.

Lei Yu's brows were slightly furrowed, but the water refining method he had obtained from the Lishui Sect appeared in the sea of knowledge, and he pondered it carefully, constantly controlling the impact of the Xuanzhong Water, not only to let these auxiliary materials fuse together, but also not to let the Xuanzhong Water destroy these auxiliary materials.

This kind of control is very demanding for the Divine Thoughts, but fortunately, Lei Yu's Divine Thoughts have reached the level of the Pseudo-Dan level after absorbing the Divine Thoughts of Black Flame, so they can control the auxiliary materials so perfectly and let them fuse together.

The mind is the same, Lei Yu's divine thoughts spread in all directions, relying on these auxiliary materials, understanding the state of each auxiliary material, so that the water of Xuanzhong can better integrate with these auxiliary materials.

As time passed, Lei Yu continued to refine these auxiliary materials, using the water of the Xuan Ming as the base to continuously fuse the auxiliary materials.

At the beginning, Lei Yu was not able to perfectly control the strength of the Xuanying Water, so much so that some auxiliary materials were turned into ashes under the weight of the Xuanying Water, but after becoming proficient, basically no auxiliary materials were turned into ashes.

This is the result of proficiency, and Lei Yu's divine thoughts are gradually relaxed, these auxiliary materials are gradually shrinking, and they are fused with the water of Xuanzhong, forming a gray light, and there is a faint gray light on the surface, as if the water is flowing.

Three days later, Lei Yu stopped cultivating, and these auxiliary materials had already taken shape, and there was no need to continue any longer.

At this moment, the Xuanzhong Water has fused with the auxiliary materials, like a gray ball, with a radius of more than ten zhang, which is quite amazing.

The method of water refining and the method of fire refining are essentially the same, the method of fire refining uses spiritual fire to melt materials, and then cast thunder soldiers, and the law of water refining is to use spiritual water to melt materials, so that they can be integrated with spiritual water, and become a new thunder soldier.

And what Lei Yu is doing now is to make these auxiliary materials perfectly integrate with the Xuanzhong Water, so that these auxiliary materials can not only maintain their own materials, but also be able to integrate the advantages of the Xuanzhong Water and become the "bottom material" of the Abyss Gun.

Obviously, Lei Yu did a very good job, with the support of the pseudo-Dan-level divine thoughts, and he perfectly fused these auxiliary materials with the Xuanzhong Water.

If it was easy to mention these auxiliary materials before, it is not so easy to lift these materials now, because there is too much mysterious water added to it, which is heavier than Mount Tai and difficult to move.

"Boy, rest for a day, recover your thoughts, and then you have to refine those six main materials, you can't ignore them!"

Yin Ming said solemnly, the six main materials are not comparable to these auxiliary materials, if you want to refine them, it will definitely take a lot of effort, and among them, thunder power and divine thoughts, which one is indispensable.

Lei Yu did not refute Yin Ming's words, in three days of refining auxiliary materials, he had almost exhausted his own thunder power and divine thoughts, and it was impossible to refine the remaining six main materials without resting.

In the center of this space, Lei Yu crossed his knees to the side, and in his left and right hands there was a white pill bottle, and from time to time he sent the Lei Yuan Dan in the pill bottle into his mouth. And more than ten zhang in front of him, the light cluster fused with the auxiliary materials and the Xuanzhong Water continued to absorb the Xuanzhong Water, and the weight became heavier and heavier.

A day later, Lei Yu stood up again, and with a wave of his hands, six materials appeared in this space.

As with the previous auxiliary materials, a steady stream of Xuanzhong water poured into it, instantly submerging the six main materials, becoming an inconspicuous presence in the black waves, and only the occasional light proved that they still existed.

The thousand-year-old cold iron stone, the Yin Yuan gold, the purple ice, the thousand-year-old blood jade, the black evil stone, and the blood spirit stone, all of which are superb existences, are naturally much more difficult to refine than the previous auxiliary materials. Even though the power of the Xuanzhong Water is extremely powerful and has endless corrosive power, it is still a little difficult to figure out the six main materials.

However, the time of the water refining method was originally very long, and Lei Yu didn't care much about this time. Although these Xuanzhong Water cannot be fused with the six main materials for a while, after a long time, the six main materials will definitely not be able to hold on, and will eventually merge with the Xuanzhong Water.

In the first five days of the sacrifice, the six materials still showed no signs of melting like an unbeatable Xiaoqiang, but after five days, the thousand-year-old blood jade among the six materials was a little unbearable.

Originally, the thousand-year-old blood jade was not a hard material, and the properties of the thousand-year-old blood jade itself were a bit yang-biased, and under the action of the Xuanzhong water, it finally began to collapse, and a layer of dark red liquid appeared on the surface.

With such a precedent as the thousand-year-old blood jade, the other five materials also began to merge with the Xuanzhong Water one after another. Suddenly, the situation became smooth, and the stone that was originally pressing on Lei Yu's heart began to slowly crack, showing signs of cracking.

With a beginning, there will naturally be an ending, and Lei Yu believes that it won't be long before these six materials will be successfully cultivated.

The Sea of Nine Shadows was dark and boundless, and the speed of time seemed to slow down, but half a month seemed to have passed for a long time.

"Boom!"

In this space, the water of Xuanzhong is turbulent, and every time Lang Hua hits, it will make a roaring sound, like thunder, which is quite terrifying.

This is a giant Lang composed of Xuanzhong water, with infinite power, a Lang flower can even shatter a huge mountain.

However, at this time, in this space, a young man is sitting in the center, his eyes closed, his face is indifferent, let the Xuanzhong water hit, but he does not move, like a rock, standing in the giant Lang of the Xuanzhong water.

And to the left of this young man, a gray ball with a diameter of dozens of zhang was constantly absorbing the power of the Xuanzhong Water, and it became more and more huge.

However, the ball was much smaller than the ball in front of the boy. Compared to the ball in front of the boy, this ball is like a small dot, and there is no comparison at all.

This is a huge round sphere, with a diameter of 100 zhang and a height of dozens of zhang, with various colors on the surface, like the center of a storm, constantly absorbing the surrounding heavy water, and the momentum is compelling.

A terrifying aura permeated this space, and the large array arranged by the Netherworld faintly trembled slightly, and it seemed that it could not bear the huge weight of this huge ball.

This is the result of the fusion of the six main materials with the Xuanzhong Water, the terrifying boundless, like a boundless black hole, wantonly absorbing the surrounding Xuanzhong Water.

"Finally merged!"

Lei Yu opened his eyes, there was a hint of joy in his eyes, after half a month of sacrifice, the six main materials were finally fused with the water of Xuanzhong, and they were so natural that they couldn't tell each other apart at all.

The huge ball in front of him was the result of his half a month, and the cultivation of the six main materials was much more difficult than he imagined, but he still survived.
