The area of Liudao Sea is nearly 300 miles in circumference, and the sea area is full of large and small islands and reefs. The islands and reefs are precipitous, and there is no grass, and from a distance, they look like sharp knives planted upside down in the forbidden sea.

When the ocean currents enter the reef, the current becomes chaotic and irregular, and there are undercurrents everywhere, making it difficult for boats to move.

As soon as Lin Yang entered the sea area of Liudao, he obviously felt that the flow of the sea water had become chaotic, and it would go east and west, and the wave chasing boat under him would also become difficult to control.

Moreover, from time to time, there is a menacing underwater undercurrent lapping on the wave chaser, making the bottom of the wave chaser rattle, as if a sword is chopping.

"The islands and reefs are like sharp knives upside down, and the flowing water is like knives, no wonder it is called the sea area of flowing knives!" Lin Yang took out a porcelain bottle and poured out a pitch-black and round elixir, which was the water-avoiding pill he got from Shi Jingtian.

When Lin Yang left the Danxia Sect, Sun Budo gave him a bottle of Water Avoiding Pills, the number of which was a full nine, plus two from Shi Jingtian, there were now a total of eleven Water Avoiding Pills on his body.

"Niu Shoujiao's perception ability is extremely strong, and it is easy to be exposed when he moves forward in a wave-chasing boat. Life matters, you can't give up the pill! Lin Yang directly took the Water Avoiding Pill.

When the medicinal power of the Water Avoidance Pill appeared, Lin Yang put away the wave chasing boat, and his body slowly sank into the chaotic forbidden sea.

Soon, a faint gaseous film slowly grew on Lin Yang's body surface.

The membrane blocks the seawater from Lin Yang's body surface, and Lin Yang breathes freely in the membrane. Moreover, the seawater will automatically avoid both sides when it comes into contact with the film, and there is no half-hindrance to Lin Yang's movement, just like on the ground.

Lin Yang used the "Mystery Technique" to collect all the breath on his body early, and in the process of his sinking, there were swimming fish passing by him, and he couldn't sense his existence at all.

I don't know how long it sank, but Lin Yang finally fell to the bottom of the sea.

The Four Pins Pill Water Avoidance Pill was really magical, Lin Yang stood at the bottom of the sea at a depth of ten thousand feet, and he actually felt half a point of pressure.

It's just that the bottom of the sea is pitch black, and he can't see at all, so Lin Yang can only rely on his divine thoughts to explore forward little by little. He didn't dare to probe his thoughts too far away, for fear of alarming Niu Shoujiao.

Fortunately, the chart marked the approximate location where there might be a deep-sea cold iron, and Lin Yang didn't need to explore the entire Flowing Knife Sea area.

However, what made Lin Yang feel tricky was that the place marked on the chart was slightly closer to the central island and reef in the Liudao Sea. Lin Yang guessed that the old nest of the ox head Jiao was likely to be on the central island and reef.

The seabed of the Liudao Sea is full of strange marine life, as well as uneven cliffs and canyons, and the scenery is breathtaking.

Lin Yang didn't have time to enjoy the beautiful scenery under the sea at this time, and he went straight towards the central island and reef of the Liudao Sea. Because he was afraid of alarming Niu Shoujiao, he not only didn't dare to probe his thoughts too far, but he also didn't dare to move too fast.

However, the sea area of the Liudao is not large, and although Lin Yang's speed is slow, it only took half a day to approach the central area.

On the seabed not far from the center of the Flowing Knife Sea, Lin Yang successively discovered the skeletons of primordial beasts of different sizes and shapes. He was now sure that Niu Shoujiao's nest was nearby.

The closer you get to the center of the Liudao Sea, the more the seabed rises, and the more and more sea platforms emerge from the sea, arching out of the islands and reefs.

Lin Yang finally stopped at the bottom of the sea, and in front of him, the huge seabed mountains towered majestically, rushing directly out of the sea, which was the central island and reef of the Liudao Sea Area.

"If there is a deep sea cold iron in this sea, there is a chance that it will be in this high mountain under the sea." Lin Yang carefully explored the surrounding environment, and finally targeted the high mountains under the central island and reef.

The high mountains under the central reef are huge and continuous, and if you look for them inch by inch, you will definitely not be able to search the entire mountain in ten days and a half months.

Lin Yang was in danger of being discovered by Niu Shoujiao at this time, and of course he didn't dare and would not take such a time-consuming and laborious method.

Deep Sea Cold Iron, which exists in the deep sea, and the temperature is extremely low, can release a cold air to the bone. On the deep seabed, the temperature of the sea is usually very low, but it generally does not freeze into a solid state.

However, in areas of the seabed where there is deep iron, the sea water freezes and the sediments on the seabed freeze.

Since Lin Yang decided to come to find the Deep Sea Cold Iron, he naturally also knew the characteristics of the Deep Sea Cold Iron. Therefore, he only needs to find the place where the bottom of the sea freezes now, and he can find the deep sea cold iron.

The medicinal effect of the water avoidance pill was only seven days, Lin Yang did not dare to delay more, and after finding the right direction, he immediately began to search up little by little from the bottom of the high mountain under the sea.

Time passed slowly, and on the third day of descending to the bottom of the Flowing Knife Sea, Lin Yang finally found a little ice crystal on the mountainside of the high mountain under the sea.

"Finally found you!" Lin Yang's face was overjoyed, and he slowly landed on a platform on the mountainside.

In front of him, a layer of fine ice crystals was forming on the huge granite.

Lin Yang gently put his hand on the granite, and immediately felt a biting chill coming from the granite.

Immediately, he slowly probed his mind into the granite, penetrating it little by little. It wasn't until he went deep into the granite two zhang deep that Lin Yang saw a fist-sized piece of white metal, which was the deep sea cold iron.

"A fist-sized piece of abyssal cold iron should be able to repair the Chaos Axe!" Lin Yang was happy again in his heart, although this piece of deep-sea cold iron was small, but the Chaos Axe was only missing a corner, and it didn't take too many materials to repair it.

However, Lin Yang soon made another difficulty, because the deep sea cold iron was in the granite two zhang deep.

Granite is a type of magmatic rock formed by the condensation of magma below the earth's surface, and it has a rather hard texture. It is almost impossible to silently take the cold iron of the deep sea out of the granite two feet deep.

"The old nest of the ox head Jiao is likely to be at the top of this high mountain under the sea, as long as it is in the old nest, I take the deep sea cold iron, it is very likely to be found by it!" Lin Yang frowned slightly, and quickly weighed it in his heart.

The deep sea cold iron is close at hand, if he doesn't take it, where will he be willing. If you take cold iron, it is very likely to alarm the Niushou Jiao and attract the pursuit of the Niushou Jiao.

After thinking about it repeatedly for a while, Lin Yang gritted his teeth and said to himself: "How can there be a reason to enter Baoshan and return empty-handed!" ”

Lin Yang decided to gamble and gamble on his luck, he thought that this place was at the bottom of the sea after all, and Niu Shoujiao would not be bored, and he had been paying attention to the movements on the bottom of the sea.

Moreover, Lin Yang also felt that although the granite was hard, with his strength, he could break the granite in an instant, and then quickly take away the deep sea cold iron, and then immediately run away, Niu Shoujiao should not be able to catch up with him.

"My luck has never been bad, this time it will definitely not be bad, it shouldn't alarm Niu Shoujiao!" Lin Yang made up his mind, his right hand slowly clenched into a fist, and then blasted out like lightning towards the granite with ice crystals.

Hearing only a muffled sound, something happened to Lin Yang's surprise, the granite received a heavy punch from Lin Yang, but there was no movement, and there was not even a trace of cracks.

You must know that Lin Yang is now in the late stage of the Golden Body Realm, and the power of one punch is so powerful that it is enough to overwhelm the mountains and seas.

However, instead of being blasted away, the unstable rocks and sea mud above it were tumbling down one after another because of Lin Yang's huge force, and the movement was not small.

Lin Yang's heart tightened while he was surprised, for fear of alarming Niu Shoujiao.

Fortunately, the ox head Jiao did not seem to notice the movement on the bottom of the sea and did not appear.

Lin Yang breathed a long sigh of relief, he now knew that the granite here had been tempered by the cold iron of the deep sea for a long time, and the hardness was far beyond that of ordinary granite, and if he didn't come up with some means, he might not be able to get the cold iron of the deep sea.

"Qing Yuan refers to? No, the attack surface is too small, and you won't be able to take out the cold iron without a ten-eight-mark Qingyuan finger. If the Qingyuan Finger is used so many times in a row, it is strange that Niu Shoujiao does not find it. ”

"Pingshan palm, it will definitely be able to shatter the granite with one blow. However, the movement of Pingshanzhang is too big, and it is difficult for Niu Shoujiao not to find it. Moreover, the Pingshan Palm is too consuming Yuan Force, and after the Pingshan Palm is cast, there is not even a few points of Yuan Power left to escape. ”

"Short sword? It shouldn't even be a Yuan soldier now, and it may not be able to break through the granite in front of it.

"Little pins? That's even worse. ”

……

Lin Yang counted his own methods carefully, and found that it seemed to be a little difficult to take out the deep sea cold iron without making too much movement.

Suddenly, his eyes lit up, and a palm-sized square seal with missing horns appeared out of thin air in his hand, which was the Shaking Mountain Seal he got from Qian Liang.

Since he got the Shaking Mountain Seal, Lin Yang has not had a chance to use it, and it is finally going to come in handy at this moment.

Shaking the mountain seal is a Xuan-level inferior yuan soldier, with good power, although he is missing a horn, but he can still exert some power.

"It's the most suitable to use the mountain seal to break the granite, but I don't know if the movement is big? Don't care so much about it for now, break the granite, I'll leave after taking the cold iron, as long as the ox head Jiao's reaction is a little slower, I should be able to get rid of it. Lin Yang then slowly injected Yuan Force into the Shaking Mountain Seal.

The mountain seal then quickly grew larger, and soon became more than one person tall, half a zhang long and wide, and slapped down fiercely towards the granite.

The sea water was abruptly discharged by the force of the mountain shaker, squeezing towards the surroundings, forming a turbulent undercurrent.

The next moment, a dull sound sounded at the bottom of the sea, as if a muffled thunder exploded at the bottom of the sea. The granite cracked in response, revealing the cold iron of the deep sea.

"The movement of the mountain seal is not small!"

Lin Yang didn't hesitate at all, and immediately conjured up a Yuan Force big hand, grabbed the deep sea cold iron out of it, and then sent it into the mad blood bead.

"Cold iron is in hand, leave!" Lin Yang was overjoyed, and at the same time, he didn't stop for half a minute, urging Yuan Li to rush towards the outside of the Flowing Knife Sea at an extremely fast speed.

It's just that Lin Yang had just run out of a distance of more than ten zhang, and a strong divine thought immediately locked him.

"Niu Shoujiao is really vigilant!" Lin Yang's face changed, and he didn't have any reservations at the moment, he pushed his speed to the maximum, and fled at a high speed against the bottom of the sea.

It's just that the Ox Shoujiao is a fourth-level Yuan Beast, its speed is extremely fast, and it is in the sea that is conducive to its speed, where can Lin Yang outrun it.

After a few breaths, Niu Shoujiao chased after Lin Yang to a distance of about twenty zhang behind him.

"No, the sea is the home of the Niushou Jiao, I can't outrun it, I have to go to the sea." Lin Yang changed direction, obliquely upward, and rose towards the sea at great speed.

At the same time, Lin Yang once again urged the Shaking Mountain Seal.

The mountain shaker quickly became larger, and then roared towards the bull head Jiao behind him.

Seeing Lin Yang sacrifice the seal of shaking the mountain, Niu Shoujiao's eyes obviously showed a look of contempt, and then he suddenly threw out a tail.

In an instant, Jiaowei swept the seal of the mountain. The Shaking Mountain Seal was immediately pulled backwards, quickly shrunk to the size of a palm, and fell into Lin Yang's hands.

"That's too strong, isn't it?" Lin Yang clearly saw that there were several more thin cracks on the mountain seal.

"Hmph, you're a bull-headed reptile! Chased and killed me in the brown sea earlier, and now you have damaged my Yuan soldiers, do you think I am honest and easy to bully? Lin Yang's eyes narrowed, and he injected Yuan Force into the Shaking Mountain Seal again.

Although the Shaking Mountain Seal was missing horns and cracks, it was still very strong and quickly grew larger, and then whistled again and slapped at the bull's head.

Niu Shoujiao didn't look at it, and pulled out another tail.

But just when Jiaowei was about to sweep the mountain seal, Lin Yang shouted angrily: "Explosion!" ”

Immediately, just listening to a bang, the Shaking Mountain Seal suddenly exploded, and Lin Yang actually directly detonated the Shaking Mountain Seal.

A Xuan-level inferior Yuan soldier, although it is missing a crack in the corner, but at least it can still sell millions of lower grade Yuan Stones, Lin Yang said that it will explode, quite decisive.

Niu Shoujiao obviously didn't expect Lin Yang to blow up the Yuan soldiers as soon as he fought, and he was caught off guard, and he was instantly enveloped by the fragments of the mountain-shaking seal that shot out from the sky.

However, after all, the Ox Shoujiao was a fourth-level primordial beast, and when the fragment of the Shaking Mountain Seal was about to die, it retracted its tail like lightning, and then its whole body was covered with a layer of green light.

After the fragments of the explosion of the Shaking Mountain Seal collided with the cyan light, the speed was noticeably paused, and then it continued to shoot towards the body of Niu Shoujiao.

The sound of puff and puff sounded in the chaotic forbidden sea, and the cyan scales the size of copper coins on Niu Shoujiao's body fell off one after another, and there were small wounds all over his body. Blood then oozed from these wounds, but it was small and disappeared as soon as it was washed away by the sea.

If it weren't for the blocking of that layer of green light, there would have been more blood holes on Niu Shoujiao's body at this moment.

Niu Shoujiao's pair of bull's eyes suddenly turned red, and it never expected that he would be injured by a human Yuan Xiu who was not even in the Hundred Spiral Realm, although it was only some skin trauma.

Niu Shoujiao was furious, eager to swallow Lin Yang in one bite.

However, Lin Yang had already taken advantage of the opportunity to blow up the mountain seal and injure Niu Shoujiao, and he accelerated and ran away.

"Moo!" The bull head Jiao let out an earth-shattering roar, Lin Yang injured it, not only injured its body, but also hurt its dignity, where would it let Lin Yang escape, the tail of the Jiaojiao, which was several feet long, shook off suddenly, and chased after Lin Yang.
