In the dark seawater, only various tiny krill and mayfly creatures emitted a faint blue and green light, and Lin Xiao used this little glimmer to see things in a radius of hundreds of zhang nearby. There are chaotic stone mountains everywhere, and there are strangely shaped deep-sea creatures everywhere, and a sea snake with a length of more than a thousand zhang but only the thickness of a wrist silently brushes the empty ball where Lin Xiao is located, but it startles Lin Xiao a lot.

Lin Xiao, who almost smashed out with a thunderbolt in his hand, barely calmed down, and passively rushed forward with the undercurrent. He had learned the forbidden spell of resisting water from Danxia, but the forbidden spell of the Great Luo Dan Dao was not very clever, and Lin Xiao's cultivation was not too high, and in the face of the undercurrent in the depths of the Black Reef Abyss, none of the spells that Lin Xiao had learned could have an effect. He could only passively rush forward, rush, rush. Several huge and ferocious sea fish opened their mouths and stuck dead behind Lin Xiao, and Lin Xiao even smelled the stench coming from their mouths.

It's just that another undercurrent rushed over, the two undercurrents collided fiercely, and a thunderclap-like loud sound came, Lin Xiao only felt that it was dark in front of him, and countless Venus flashed, and he was almost stunned by this loud noise. The thin black light outside the body flickered for a while, and the violent pressure caused by the collision of the undercurrents was easily dissolved by the black light, which saved Lin Xiao from the pain of being crushed into pieces by the loud noise hitting his brain.

The undercurrent that rushed from the rampage enveloped Lin Xiao and led him tumbling towards the deeper bottom of the sea. Lin Xiao flipped a few times in the undercurrent, barely stabilized his figure, and stared blankly at the black mountain rocks that flashed around, and his heart was at a loss, not knowing how to get out of this predicament. Suddenly, a little dazzling red essence light appeared in a black stone mountain, Lin Xiao's eyes lit up, and he pointed at the red essence light and shouted: "Oh my God, Hai Bodhi! One flower and eighteen leaves, the whole body is covered with red light, this is more than 10,000 years old Hai Bodhi!"

Before he could finish this sentence, the undercurrent wrapped around Lin Xiao and rushed out for several miles, scurrying around the messy black stone mountain for a while, and Lin Xiao couldn't find where the stone mountain with Hai Bodhi was at all. Lin Xiao was so anxious that he jumped straight in the empty ball, and he didn't know what he was shouting about. The sea Bodhi, which has been in fire for 10,000 years, is an important medicinal material needed to refine the eighteen 'Tianzi-level' elixirs of the Great Luo Dan Dao. If Hai Bodhi is used as the main medicine, it can refine the 'Tianzi-level' elixir 'Liberation Pill', which is a good treasure that can help the scattered immortals survive the six or nine tribulations!

Out of the instinct of an alchemist, Lin Xiao's heart was so painful that his heart was about to break. He looked up at the sky helplessly, and sighed: "Hai Bodhi, the sea Bodhi of ten thousand years of fire, oh my God!"

This time he raised his head, and Lin Xiao was stunned again. The undercurrent swept around the summit of a stone mountain that he was running over, and there was a kelp that emitted a faint white light floating faintly. "Heavenly Fragrance Jade Food, this is the extinct Heavenly Fragrance Jade Food! Oh my God! In a remote place like Arcturus, how can there be Heavenly Fragrance Jade Food?" Lin Xiao became excited again, he jumped around for a while, like a monkey with a burned tail, and his mouth kept letting out a roar of unknown meaning. He quickly turned over the records of the Great Luo Dan Sutra in his mind, well, no ancestor of the Great Luo Dan Dao had ever penetrated deep into the Black Reef Abyss, so no one knew that these elixirs that could no longer be estimated in the current cultivation world had grown here.

The undercurrent swept Lin Xiao and rushed forward for more than ten miles, Lin Xiao looked back at the messy stone mountain in a daze, and really had the urge to cry without tears. Tianxiang Jade Food, which is the main medicine that can refine the 'Rejuvenating Pill' that can bring the dead back to life, is a legendary immortal seed. Lin Xiao really wanted to cry, he closed his eyes and never looked at the scene outside.

Lin Xiao closed his eyes, so he didn't really go crazy in the next blow. The undercurrent took Lin Xiao to rush forward, and along the way, there were dozens of elixirs that were listed as 'immortal products', 'supreme products', and 'superb products' in the Great Luo Dan Sutra. If Lin Xiao saw the figures of these elixirs, but couldn't touch them at all, Lin Xiao would really be hit crazy. In particular, there was actually one of them that was the main medicine for refining the Reincarnation Pill, which would make Lin Xiao have a direct mental breakdown.

Fortunately, Lin Xiao didn't open his eyes, he resigned himself to his fate and sat cross-legged in the empty ball, allowing the undercurrent to lead him to the unfathomable depths of the sea.

I don't know how long later, when Lin Xiao was so bored that he was about to doze off, the undercurrent finally brought Lin Xiao to a bottomless trench. This trench is a few miles wide, but I don't know how long, I don't know how deep, I can't see the edge left and right, look down, the dark trench seems to penetrate the center of the earth, a trace of cold air is constantly floating from the trench, there are countless thin broken ice floating near the trench, even if it is impacted by the undercurrent, these broken ice are also not moving, it is very strange.

It seems that all the undercurrents of the Black Reef Abyss originate from this trench, and countless dragon-like rushing and roaring undercurrents continue to rush out of the trench, rushing in all directions, and countless undercurrents roaring and twisting from all directions, fiercely plunging into the trench. One in and one out, countless undercurrents collided and rubbed against each other, and the violent dark energy rushed, shaking the nearby ground trembling. The ground near the trench was flat and unbumpy, and all the rocky hills and reefs were shattered by these undercurrents.

Only the palm-sized pieces of crushed ice slowly floated from the trench, just suspended quietly in the water around the trench. Even if those undercurrents collided and exploded around them, enough to destroy a small mountain, the broken ice still did not move, just followed a fixed trajectory, slowly drifting on its own.

Lin Xiao was engulfed by that undercurrent, and rushed headlong towards the trench.

Lin Xiao saw the terrifying scene of countless undercurrents near the trench hitting each other and turning the seabed upside down, and he couldn't help but scream in fright. Several undercurrents collided together less than a mile on his side, and a huge amount of seawater splashed out at an extremely high speed in the undercurrent, and the white water ripples swept around, and the water ripples rubbed against each other on the bottom of the sea, and actually splashed a large area of sparks! The 'booming' sound shook Lin Xiao's body even more, and blood spurted out of the seven orifices.

Fortunately, the undercurrent where Lin Xiao was located did not collide with other undercurrents, but took Lin Xiao into the trench. The countless palm-sized thin pieces of ice pierced through the undercurrent like a phantom and slashed straight towards Lin Xiao. Lin watched in a daze as those thin ice rushed towards him, and before he could figure out a way to deal with it, the black light outside his body had already trembled violently, and circles of black ripples rippled on the black light, and pieces of thin ice that shot rapidly were directly fused into the black light, as if they were swallowed by the black light.

Lin Xiao looked at the ripples in horror, and he clearly sensed the extremely strong power contained in those thin ices. It was a powerful force that was enough to break his body to pieces, but it was blocked by this thin layer of black light~ No, it was devoured! Lin Xiao slapped his forehead vigorously and shouted loudly: "I'm confused, what's going on with this black light? Where did it come from? Hmm, when I woke up just now, I was so frightened that I forgot about it!"

Soon, Lin Xiao didn't have to wonder where this black light that protected him came from. The Xuanwu Ring was like a tiger that smelled the aroma of flesh and blood, and rushed out of Lin Xiao's body with a gentle sparkling black light. Xuanwu swirled around Lin Xiao's body for a while, the ring expanded to Zhang Xu Fangyuan, and a human-sized Xuanwu phantom came out of the Xuanwu ring, opened its big mouth and sucked it around, and the dense collection of hundreds of billions of thin ice on the trench was like a bird throwing into the forest, obediently bringing cold light and flying over.

Lin Xiao's eyes widened, he only heard the crisp sound of thin ice tearing through the sea water in all directions, and countless cold lights shot out rapidly, and gradually, Lin Xiao's body was covered by the rapidly circulating snow-white light. Lin Xiao only felt that the cold air emanating from the thin ice made his body stiffen, and a trace of sharp cold air was scraping around on his body, causing Lin Xiao to have goosebumps. Those thin ices turned rapidly against Lin Xiao's body, and they kept throwing themselves into the big mouth of the Xuanwu Phantom.

As more and more thin ice was absorbed, the Xuanwu phantom gradually became condensed and solid, gradually changing from a hazy shadow to a vague state of almost clouds.

In just a short moment, the hundreds of billions of thin sheets of ice floating on the trench were swallowed up by the basalt ring. Sensing that there was no longer the sharp sound around him, Lin Xiao slowly opened his eyes. Just when he saw the Xuanwu phantom released by the Xuanwu ring, he burped lightly, and glared at Lin Xiao a few times, the body of the phantom shook slightly, and the volume seemed to expand a little, from the size of a human head to the size of a pig's head, but its newly condensed body became a lot hazy and dim.

Lin Xiao looked at this Xuanwu phantom, and the Xuanwu phantom also blinked and looked at Lin Xiao with small eyes. Lin Xiao's serious attitude towards the Xuanwu Phantom made a big gesture, and said very sincerely: "Several life-saving graces, the boy Lin Xiao has nothing to repay." After speaking, Lin Xiao made a deep sigh again. I don't know why, when this Xuanwu phantom glared at Lin Xiao, Lin Xiao instinctively noticed that this phantom seemed to be a living thing, not just an image of a treasure.

The Xuanwu Phantom stretched his neck, looked at Lin Xiao, and suddenly screamed twice. It yawned, and spewed out a dense black vapor spray on Lin Xiao's face, and its body turned into a black light, which merged into the Xuanwu ring. Xuanwu circled around Lin Xiao a few times, retracted Lin Xiao's dantian, and continued to put Lin Xiao's golden pill in the ring, slowly absorbing the heavenly fire qi that seeped out of the golden pill.

This piece of water vapor hit Lin Xiao's face, Lin Xiao only felt a chill all over his body, his body lost all consciousness in that instant, and even his divine sense was frozen. But it was only a moment's effort, Lin Xiao felt that a cool breath flowed through his body from the face door, like a red-hot iron ingot being quenched by a cold spring, and the impurities in Lin Xiao's body due to cultivation were cleaned up, and it seemed that his spirit was a lot clearer. In particular, Lin Xiao's skin has become white and delicate, moist and smooth to the extreme, and the skin is even covered with a faint white light.

Just feeling the changes in his body, and was guessing what the Xuanwu ring that Jiang Zizi gave him was, Lin Xiao suddenly shook his body and fell to the ground with a 'bang'. But it was the undercurrent that enveloped Lin Xiao that had rushed to the bottom of the trench, and the undercurrent hit the bottom of the sea and became fragmented, and Lin Xiao, who was shrouded in a black ball of light, was thrown out, rolled on the ground a few times, and hit a big rock before stopping.

Standing up slightly embarrassed, Lin Xiao quietly looked at the scene at the bottom of the trench.

The bottom of the wide trench was uneven, and a trace of cold air continued to rise from the ground, slowly condensing into patches of thin ice and floating upward. Lin Xiao took a general look at these places where the cold air was wafting, and was stunned to find that there was actually some smell of Qimen formations in them, obviously the generation of this cold air was man-made, not a miracle of the natural generation of heaven and earth. It's just that except for alchemy, which is the top means of the cultivation world, the other strange sects are ignorant, and Lin Xiao can't see the clues and good or bad of this formation.

However, to be able to arrange a formation at such a huge trench, this person's cultivation can only be described as shocking. Lin Xiao didn't know how powerful this formation was, and he didn't know how it would trigger the formation, so he could only cautiously follow the cliff on the side of the trench and randomly choose the direction on his right hand to move forward.

To be precise, this is not the direction chosen by Lin Xiao, but chosen by Xuanwu Huan. Because the ball of light released by the Xuanwu ring to protect Lin Xiao's body protruded slightly in that direction, as if a finger was pointing in that direction. Lin Xiao couldn't figure out the situation below, so he naturally moved forward according to the guidance of the Xuanwu Ring.

From time to time, a violent undercurrent would fall straight down from the top of the trench, and when it landed, the torrent shot indiscriminately, like a spear thrown and sparks flashed everywhere in the trench. Lin Xiao walked cautiously in the turbulent water with difficulty, lest he be hit by this violent undercurrent. Although there is a Xuanwu ring body, Lin Xiao feels that his safety is guaranteed, but if he is hit by the turbulence, Lin Xiao's small body does not know where it will be bombed, and Lin Xiao does not dare to make the slightest mistake in this dangerous place.

After more than two hours of marching, the cold air in front of us became worse and worse, and at the bottom of the trench, a small pond even appeared. The pond was full of viscous black liquid, and the sea water on all sides was forced by the cold air released by the black liquid, constantly generating pieces of thin ice to float upward, but near the pond, there was a vacuum with a radius of hundreds of zhang, and not a drop of sea water could get close to the pond. In that acre of Xu Fangyuan pond, there is actually a black willow growing, which is only more than two zhang high weeping willow without wind, thousands of slender branches dance lightly, just looking, it gives people a very quiet, very peaceful, very comfortable feeling.

Just below the willow tree, there was a jade plate floating on the black pond, and the purple and cyan jade plate faintly emitted a trace of glow, which was obviously a good magic weapon. On the jade board, an old man in a black robe sat cross-legged, his hands clasped in front of the dantian, but he didn't have any breath at all. The old man's body was like a baby's, and the group was no more than two feet long. A drop of pearl-like black and gray spiritual dew slowly rolled down on the branches and leaves of the willow, dripping on the old man's body, and actually made the sound of gold and iron clashing.

The Xuanwu ring flew out of Lin Xiao's body again, and the Xuanwu virtual image also showed its figure, salivating at the black pond and the black willow. It's just an illusory image formed by energy condensation, but Lin Xiao can feel the strong desire to take possession of the black pond and black willow from its body.

"This is ~~~" Lin walked into the empty space next to the black pond without a drop of water in surprise.

A terrifying cold aura penetrated through his body, and Lin Xiao's body instantly turned into a miserable white color peculiar to ice cubes. The Xuanwu ring roared softly, and a black light sprinkled on Lin Xiao's body, and Lin Xiao, whose body was about to collapse because of the terrifying cold, took a breath, the white color of his body gradually faded, and his body regained consciousness. Lin Xiao took a few steps back in horror and muttered in a low voice: "What is this? Kwai Shui Yuan Essence? No! Dark Water Elite? No! Then, what else is there in heaven and earth that is liquid, but it has such a cold aura?"

Xuanwu Phantom glanced at Lin Xiao sneeringly, his eyes full of disdainful ridicule. Lin Xiao clearly sensed that this Xuanwu phantom was laughing at himself: Xia Worm could not speak of ice.

Lin Xiao rolled his eyes angrily, but he was also helpless about this Xuanwu ring, he couldn't be angry with a magic weapon, right?
