Lei Yu sat on the shore, concentrating. In front of him, a group of dark yellow hills flashed, and streams of black smoke emerged from the hills, clearing away the impurities on these auxiliary materials.
Although "Nine Nether Underworld Thunder" is not as good as underworld water, it is still an extremely powerful strange thunder. It is certainly not a problem to remove impurities from these auxiliary materials.
Time is passing slowly, and the yellow hill in front of Lei Yu is gradually shrinking. This is the result of the removal of impurities. Although the size of the hill is not as good as before, the light it emits is even brighter, like gold.
It's still flickering, not like the one with a sickly look before.
When the size of the hill shrunk to half, Lei Yu finally opened his eyes. There was a look of satisfaction in his eyes. His mind was attached to these auxiliary materials, and the removal of impurities from these materials was naturally a problem.
It's crystal clear.
"Nine Nether Underworld Thunder" is indeed the main magic thunder of the Hell Demon Sect. It is also very effective in removing impurities. All these impurities were cleaned up in a short period of time.
"open!"
Lei Yu stood up and said calmly.
As his voice fell, the golden light of the hill-like pile of auxiliary materials became even brighter, but then the light faded, and a pile of various materials appeared in front of Lei Yu.
This pile of materials is obviously smaller than before, and some materials have even shrunk seriously. They are only average or even less than the previous ones. However, Lei Yu understands that these are the best parts. Using these materials to refine the Shen Yuan Gun has a higher success rate.
There will also be some improvement.
With a wave of his hand, Lei Yu put the pile of materials directly into the space bag. There was a hint of hesitation in his eyes as he looked at the Nine Nether Sea in front of him.
The black sea surface calmed down, and the Nine Nether Sea was like an oversized stone inkstone filled with ink, dyeing everything ink black without any luster.
However, this stone inkstone is not ordinary. The Nine Nether Sea in the "Nine Netherworld Thunder Bell" is only 9,900 miles long. Compared with the Nine Nether Sea in the underworld of hell, it is like a small speck, but no one dares to
Ignore the Nine Nether Sea here.
This is the Nine Nether Sea that Emperor Jiuyou personally arranged. It is full of dangers, and there are countless ghost beasts in the sea. Even strong men in the Thunder Infant stage may not be able to get out if they enter it.
"Boy, what are you going to do next?"
Yin Ming asked. Although Lei Yu had said that he would refine the Shen Yuan Spear using water refining, he didn't know how Lei Yu would refine the Shen Yuan Spear. That's why he asked this question.
"The water refining method must of course be refined with water. Isn't the Nine Nether Sea in front of me the best place for cultivation? Senior, you are by my side to protect me. I want to enter the Nine Nether Sea.
Refining the Shen Yuan Spear under the sea."
Lei Yu's eyes burned with golden light emerging, full of confidence. He had already thought about it. There were only a handful of spiritual waters in the world that could be used to refine the Shen Yuan Gun, and the sea water in the Nine Nether Sea was one of them.
one.
Among the seawater of the Nine Nether Sea, the best quality is of course the water from the bottom of the Nine Nether Sea, so Lei Yu has to enter the Nine Nether Sea for refining.
This is an adventure. No one knows what is on the bottom of the Sea of Nine Netherworlds. Lei Yu is sure that he will encounter many difficulties. However, if the Shen Yuan Spear can be refined on the bottom of the Sea of Nine Netherworlds, then Shen Yuan
The power of the Abyss Spear is naturally unimaginable.
"Boy, please wait for me..."
There was a trace of anxiety on Yin Ming's face, and he wanted to say something, but he couldn't speak in the middle of the sentence, because Lei Yu had turned into a thick yellow light and entered the Nine Nether Sea.
"Bang!"
A soft sound came from the Nine Nether Sea, and ripples started to appear in the originally calm Nine Nether Sea, spreading in circles to all directions.
"Hey, this kid is really messing around. Don't you know how dangerous the bottom of the Nine Nether Sea is? Forget it, it seems that this kid wants to refine the Shen Yuan Gun this time, so I will help him. If so.
If any danger arises, I can rush there as soon as possible."
Yin Ming felt angry for a while, but there was nothing he could do. Lei Yu was going to kill first and then attack. Even with his speed, he couldn't stop him. At that moment, Yin Ming also entered the Nine Nether Sea.
"Is this the bottom of the Nine Nether Sea?"
A darkness shrouded the seabed of the Nine Nether Sea in the depths of Leiyu. Waves of cold breath rushed towards him, one after another, as if to freeze him into an iceman.
There is not much difference between the bottom of the Sea of Nine Netherworlds and the surface of the sea. They are both the same black, but thicker. If the Sea of Nine Netherworlds above the sea surface is light ink, then the bottom of the Sea of Nine Netherworlds is thick ink.
, almost nothing could be seen, and there was only a thick blackness in the eyes.
Moreover, from time to time, there are waves of filthy things coming to his side, trying to invade his body. Although Lei Yu is not afraid of these filthy things with his current strength, he still feels a little upset, and has no choice but to attack his body.
A layer of thick yellow barrier was placed around it, not only to prevent the contamination of these filthy things, but also to keep warm.
Lei Yu entered the Nine Nether Sea and gradually sank down, five feet, ten feet, fifty feet, one hundred feet... Lei Yu sank deeper and deeper, and the darkness around him became heavier and heavier. In the end, even if he
His spiritual sense could only detect a distance of three feet in radius, let alone his eyes, which could only be regarded as blind.
"It's so cold!"
Estimating that he had sunk to a depth of several hundred feet, Lei Yu finally stopped. He hesitated because the sea water here was too cold. Even if he used thunder to protect himself, he still felt a sharp pain.
severe cold.
This kind of coldness was pervasive. Not only his body, but also his thunder power began to run sluggishly. Some of it stopped running, and its efficiency was only half of what it was before.
Not only that, reaching the depth of hundreds of feet, the pressure on Lei Yu also increased exponentially. He felt like he was half pressed by a huge mountain, his chest felt a little tight, he couldn't breathe, and the consumption of thunder power was even greater.
It is extremely growing.
Although he prides himself on his extremely strong natural thunder power, Lei Yu also feels a little uneasy in this place hundreds of feet deep. Without him, the speed of thunder power consumption is too alarming, even for him who doesn't pay much attention to thunder power.
People are also a little overwhelmed.
"This is it. If you go any further, my body won't be able to bear it anymore."
Lei Yu frowned slightly and looked at his feet. A dark abyss was shrouded, as if there was some giant underwater beast lurking in it. An inexplicable feeling of fear arose in his heart.
Seven hundred feet is the deepest he can dive. If he goes any further, he may be in danger. After all, this is not on land, but deep under the sea. If he is not careful, he may come up again.
Not going.
"Boy, you really don't want your life. You want to break into the bottom of the Nine Nether Sea before you have cultivated enough. Do you want to die?"
An angry voice came into Lei Yu's mind. The tone was very urgent, but it made him feel warm, because this person was none other than Yin Ming.
A wave of waves rushed towards Lei Yu, and soon, an old man with black hair and wrinkles on his face appeared less than ten feet away from Lei Yu. Who else could it be if it wasn't Yin Ming.
At this moment, Yin Ming's face was full of anger, as if he was about to take action at any time. A wave of evil energy emanated from Yin Ming's body, making Lei Yu feel frightened.
Yin Ming was really angry this time. Lei Yu's approach of killing first and then showing off undoubtedly angered him. Even if he doted on Lei Yu again, he would take this opportunity to teach Lei Yu a lesson.
"senior!"
Lei Yu said with a stern face. He also knew that Yin Ming was angry and did not dare to say anything. This time, he was indeed too reckless. It was normal for Yin Ming to punish him.
"Boy, do you feel that your wings are stiff, and you even dare to break into the bottom of the Nine Nether Sea? Don't you know how dangerous the bottom of the Nine Nether Sea is? You can't enter the Nine Nether Sea with your current strength.
You can only die at the bottom of the sea."
Yin Ming had a stern face. As the weapon spirit of the "Nine Netherworld Thunder Bell", he certainly knew how dangerous the Nine Nether Sea was. It was already very dangerous above the sea surface, let alone at the bottom of the Nine Nether Sea.
!
It can be said that Lei Yu was lucky to be able to dive to a depth of 700 feet without encountering danger. If other cultivators had entered the Nine Nether Sea, they might have died long ago. After all, not everyone
They all practice "Nine Nether Underworld Thunder" like Lei Yu.
"Senior, I just want to refine the Shen Yuan Spear better!"
Lei Yu said aggrievedly that it was for the sake of the Shen Yuan Spear that he was willing to risk entering the bottom of the Sea of Nine Nethers in order to use the best water of the Nine Nethers to refine the Shen Yuan Spear.
"snort!"
Yin Ming snorted coldly and ignored Lei Yu, but then his face changed slightly, and he suddenly shouted at Lei Yu: "Run!"
Yin Ming's voice was so urgent and fast that Lei Yu was a little confused, but then he felt a sense of danger coming from behind him, and a cold air enveloped him, making his body unable to move.
"Buzz buzz!"
Waves of sounds like the buzzing of bees came from behind Lei Yu, endless and harsh, confusing the surrounding seawater.
Waves of fluctuations came towards Lei Yu, causing his body to shake uncontrollably. Even the stupidest person would feel abnormal, let alone Lei Yu.
He did not turn his head, and his spiritual thoughts dispersed behind him. In an instant, a shadow formed in his spiritual thoughts, which was very terrifying.
This is a group of fish that Lei Yu has never seen before. Their whole bodies are silvery white, and their heads seem to be swollen. They are huge, occupying at least one-third of their bodies. They are veritable big-headed fish.
And considering that these fish are a full foot long, you can imagine how big this fish head is.
This school of fish was so densely packed that Lei Yu roughly estimated that there were at least several thousand fish. They all opened their silver fangs and rushed towards Lei Yu, as if they wanted to tear him into pieces.
