-------------------------------------

In the following time, Han Changlin basically spent his time in the cave mansion studying the "Spirit Fetus Infant Separation Method" recorded in the Forbidden Yuan Array Dao and the Yantian Immortal Sutra, in addition to refining the array flag and array disk.

Before refining the Array Banner Array, Han Changlin also specially studied dozens of formations in the Forbidden Yuan Array, and finally chose the "Cold Water Thunder Light Array" and the "Five Elements Lock Demon Array" respectively

These two formations know from the name that one focuses on attack, and the other focuses on defense, the "Cold Water Thunder Light Array" can form endless attacks through thunder light water arrows, and this formation focuses on water attributes, on this boundless and wide sea, it can exert extremely amazing power.

As for the "Five Elements Lock Demon Array", through the principle of mutual growth and restraint of the power of the five elements, the Five Elements Binding Spirit Silk is formed to lock the people or demon beasts in the array, and no matter how much these Five Elements Binding Spirit Silk is cut off, it can be repaired in an instant.

Unless the spirit stones used for the operation of the formation are exhausted, or the other party's mana is too strong, it can block the power of the five elements in an instant and destroy the array flag array in the eyes of the array, and this formation can be broken.

After thoroughly understanding these two formations, Han Changlin began to refine them.

And in the process of refining the Formation Banner Array of these two formations, Jiang Yingxue had also come several times to ask him about his confusion in cultivation, and Han Changlin also pointed out one by one, and after his Yun Ling Pill was used up, he gave her a few bottles, and told her to work hard to cultivate.

Jiang Yingxue also did not live up to Han Changlin's expectations, in just three years, she had cultivated to the sixth level of qi refining, and at this cultivation speed, within ten years, Jiang Yingxue might be able to build a foundation.

This really made Han Changlin a little surprised, thinking that it had taken him more than ten years to cultivate to the foundation building period, and this was still under the supply that he had enough elixir, of course, Jiang Yingxue was by his side, although Han Changlin was not open to supply the elixir used in his cultivation, but every few days, it was still possible to take a pill of the elixir.

After analyzing it, Han Changlin believes that there are probably two reasons, one is that the body chosen by Jiang Yingxue's reincarnation has very good spiritual root qualifications, and now it seems that it is undoubtedly the spiritual root of the earth.

On the other hand, Han Changlin thought that Jiang Yingxue was a high-level cultivator in her previous life after all, although she didn't know anything about her previous life after being reincarnated, but the kind of fit for cultivation in the depths of her soul should also affect Jiang Yingxue now, and her talent in formation can also explain this very well.

On this day, Han Changlin was holding a colorful array flag in his hand, with a satisfied expression on his face, after three years, he finally refined all the array flags used in these two formations.

Moreover, by refining these array flag arrays, Han Changlin's attainments in the formation have also deepened a lot, at least for the two formations of "Cold Water Thunder Light Array" and "Five Elements Lock Demon Array", they have reached the point of insight into the metaphysics.

With the help of these two formations, Han Changlin thought that he already had the conditions to go to the endless open sea to practice, plus his natal magic weapon, Qingyang Jianling Treasure, and the "Sky Blue Divine Sand" given to him by Jiang Yingxue in his previous life, it should be enough to protect himself.

After three years, this "Azure Divine Sand" has also been re-refined by Han Changlin, and it has been able to send and receive from the heart, this Azure Divine Sand is worthy of being refined by the Yuanying Monk through secret techniques, and the power is extremely great, and Han Changlin has also specially verified it.

Once this bottle of "Sky Blue Divine Sand" is sacrificed, it can cover a radius of two or three hundred zhang in an instant, and every grain of Azure Divine Sand will turn into a fist-sized blue divine sand, each of which weighs dozens of catties, and the surface also contains ten thousand poisonous miasma.

For immortal cultivators, in the area covered by this Azure Divine Sand, it is almost impossible to cast a magic weapon, just if they want to pass through the range of these two or three hundred zhang, as long as the magic weapon is not tough enough, I am afraid that it will be directly destroyed in this endless divine sand.

Even if it is a Yuanying monk, if he is trapped in this heavenly divine sand, if he wants to break out, it will take a lot of effort, as for ordinary Jindan monks, if he is trapped in it and wants to rush out, unless he has cultivated some magical secret techniques that can restrain this kind of divine sand, there is a high probability that he can only let Han Changlin slaughter it.

Of course, this Azure Divine Sand is not really invincible, whether it is a magic weapon or a secret technique or a spell in the Immortal Cultivation Realm, they are all mutually reinforcing, there is no absolute invincibility, the same is true of this Azure Divine Sand, and the nemesis of the Azure Divine Sand happens to be the bursting fire spell such as the Six Flame Bursting Techniques cultivated by Han Changlin.

Of course, some cold flame spells can also restrain the ten thousand poisonous miasma on the Azure Divine Sand, and this Azure Divine Sand also has a disadvantage, that is, once the ten thousand poisonous miasma on the divine sand is broken by the flame spell, unless it is to find another place with ten thousand poisonous miasma and re-practice for several years, it will not be able to recover on its own.

After understanding this, Han Changlin also had a cautious idea of using this Azure Divine Sand, unless it was a last resort, it could not be sacrificed easily.

But it's a different story for demon beasts, the secret magic powers cultivated by immortal cultivators are endless, unless they have experienced a tragic battle with them, it is almost impossible to understand all their secret techniques, but demon beasts are relatively simple, for the demon beasts in the endless open sea, Han Changlin can also understand five or six percent through the purchase of some books introducing demon beasts.

The demon beasts recorded in these books are all some common species in the endless open sea, and the attack methods they have are also well understood, for this kind of demon beasts, Han Changlin naturally has no scruples when he kills them.

Of course, the remaining four or five achievements are another matter, demon beasts are not like human monks, different kinds of demon beasts often cross classes, giving birth to strange and strange monsters, this kind of demon beasts have magical spells, but they are also varied, for this kind of demon beasts, the human race immortal cultivators have to be extremely careful.

After thinking about this, Han Changlin summoned Jiang Yingxue through the technique of sound transmission.

Jiang Yingxueqiao's face was full of doubts, and she came to the living room in Han Changlin's cave mansion and stood with her hands down.

"Master, you summoned Yingxue to come, do you have something important?"

This doesn't matter how strange Jiang Yingxue is, after cultivating on Qinghu Island for more than three years, his master has always lived in a simple place, and unless he went out to buy materials, he basically didn't even go out of the cave door.

And in the past three years, the master has never summoned himself once, but every time he encounters difficulties in cultivation, he will take the initiative to come to ask for advice, and after more than three years of getting along, Jiang Yingxue also knows that his master has always been clear in his work, and he will not summon himself if he has nothing to do.

Looking at Jiang Yingxue's pretty face, Jiang Yingxue is no longer the laundry girl she was back then, at this moment she is wearing a red and pink robe, combing a ponytail, and the ponytail is slightly tilted, with a little playfulness.

Her face is also fair and smooth, compared to a few years ago, it can be said that it is a world of difference, the only drawback is that Jiang Yingxue is the same as in her previous life, she is petite, and if she is straight, it is only to the position of Han Changlin's chest.

Looking at his apprentice, Han Changlin showed a gentle expression on his face:

"Yingxue, for the teacher, you have to go to the endless open sea to cultivate for a period of time, during the time when the teacher is away, you must cultivate well, and you can't have a moment of slackness."

"Is the master leaving?"

Hearing this, Jiang Yingxue's face turned pale, the master is gone, and she doesn't know when she will come back, and she doesn't feel that she gets along day and night, but now that she heard that Han Changlin was leaving, Jiang Yingxue couldn't help but feel a sense of loss, as if she had suddenly lost her support.

Seeing Jiang Yingxue's expression, Han Changlin couldn't help but wonder:

"Silly boy, the teacher is not leaving, but just going to the endless open sea for a period of time, if it is short, he may come back in a few years, and during the time when the teacher leaves, he will also leave you some elixir to assist you in cultivation, and the teacher also knows that your attainments in the formation are not inferior to the teacher at all, so that during the time when the teacher leaves, you can also refine some formations by yourself to protect the cave mansion, and at the same time to protect your own safety."

When Jiang Yingxue heard this, her face returned to normal, and then she said in a slightly coquettish tone:

"Then the master must come back as soon as possible, otherwise Yingxue will encounter problems in cultivation, but no one will answer them."

"Don't worry, the teacher will come back as soon as possible."

After Han Changlin finished smiling, he took out a few bottles of Yunling Pill from the storage ring, as well as an emerald green jade bottle, and a white jade slip.

"In this jade bottle is a Zhuji Dan, if you can cultivate to the Great Perfection of the Qi Refining Period, you can try to build a foundation, as for this jade slip, what is recorded in it is an exercise called "Jinxia Wujie", which is a gold system exercise obtained by accident for the teacher, and after you build the foundation, you can practice."

Jiang Yingxue saw that the master had thought so well for herself, and her pretty face couldn't help but show an excited expression, he took these items from Han Changlin's hand, and his eyes showed an expression of joy.

After Han Changlin pondered for a while, a pair of silver hook magic weapons flashing gold and red, as well as a golden shield magic weapon, appeared in his hand.

"Now that you have cultivated to the sixth level of qi refining, you can't do without a decent magic weapon, these two superb magic weapons are my treasures, and they have never been sold, so I will give them to you."

Jiang Yingxue happily took the two magic weapons from Han Changlin's hand, and her small mouth also wiped honey and thanked Han Changlin repeatedly.

Han Changlin then left Jiang Yingxue a thousand lower-grade spirit stones for her to buy the materials for refining the array flag array plate, and after doing all this, Han Changlin sent Jiang Yingxue away.

After thinking about it in the cave for a while, Han Changlin left the cave mansion, and a blue-red spiritual light appeared around his body, turning into a spiritual light and rushing into the sky, flying towards the depths of the endless open sea, and disappearing between the sea and the sky in the blink of an eye.

......

The Black Abyss Sea, located to the east of Thunder Stone Immortal City, 80,000 miles away, is a huge sea area that covers a radius of tens of thousands of miles.

The reason why this black abyss sea is very famous is because the sea water here is pitch black, which is not that this sea water is different from the sea water in other places, but around this black abyss sea, the water depth is only about a thousand zhang, and the water depth of the black abyss sea has dropped sharply to ten thousand zhang, which makes this sea area look pitch black.

Han Changlin stood on top of the void hundreds of zhang high, and casually emitted a blue and red sword light, killing a four-legged monster fish that didn't know whether to live or die, and rushed out of the sea to try to attack Han Changlin, with a contemplative expression on his face.

With his current realm, in this endless open sea, it is naturally not difficult to kill ordinary second-order demon beasts, but if he wants to speed up the improvement of the proficiency of the two intermediate spells, of course, it is better to kill third-order demon beasts.

However, in this endless open sea, it is not difficult to find some second-order demon beasts, but it is not easy to find a third-order demon beast.

Third-order demon beasts are already the leader level among demon beasts, they usually control a sea area, and they also have thousands of second-order and first-order demon beasts under their command, so if they want to kill a third-order demon beast, they usually have to kill countless low-order demon beasts by the way.

But Han Changlin searched for tens of thousands of miles in this Black Abyss Sea, and except for some second-order demon beasts, he didn't even encounter a single third-order demon beast.

At the same time, he also thought that at the auction held by the Dongtian Commercial Bank, he had heard someone say that the number of third-order demon beasts in the Ten Thousand Demon Sea was now very rare, and it was because of this that the price of third-order materials and some magic seals had skyrocketed.

At that time, Han Changlin listened to it and didn't care, but now it seems that most of these words are true, which also makes Han Changlin feel a little strange, where have these demon beasts gone, could it be that he feels that he can't resist the human race immortal cultivators, and fled into the depths of the endless open sea?

This reason even Han Changlin felt a bit far-fetched, as far as he knew, the Terran monks had always taken the method of cutting steamed buns, through the experience of countless monks, killing demon beasts, expanding the sea area, and encroaching on the territory of demon beasts little by little.

This also leads to the fact that every few hundred years, the demon beasts cannot bear the encroachment of the Terran monks, and will launch a large-scale attack, and at this time, the sea area that the Terran monks have encroached on for hundreds of years usually have to return a part of it.

But on the whole, the Terran monks still have the upper hand, and the sea area under their control is also slowly expanding, such as this Black Abyss Sea, which was still the domain of demon beasts more than a hundred years ago, has now become a place of trial for Terran monks.

Along the way, Han Changlin also saw several waves of Terran monks, several people formed a team to hunt the demon beasts in the Black Abyss Sea, they usually sent one person to attract the attention of the demon beasts, and once the demon beasts chased after it, they would be fooled, and after chasing for a while, they would be surprised to find that they were surrounded by several Terran monks.

However, these second-order and first-order low-level demon beasts have not very high IQs, as long as the Terran monks are a little cautious, they can still gain a lot.

Han Changlin's purpose was not this kind of sporadic low-level demon beasts, but more second-order demon beasts, or third-order demon beasts, but in this vast sea area, Han Changlin had been looking for a long time, but he had never seen such a group of demon beasts appear.

Thinking of this, Han Changlin controlled the light and continued to fly towards the depths of the Black Abyss Sea, disappearing between the sea and the sky in the blink of an eye.

"Huh?"

On this day, Han Changlin saw a small island from a distance, only a few miles in size, and on the island, there were five immortal cultivators in the foundation building period, besieging and killing a second-order high-level crocodile demon beast.

The scale armor on the crocodile demon beast was abnormally strong, and it withstood the attack of the five-person magic weapon, and the sparks were everywhere, but it was unharmed, obviously the five people wanted to kill it, and it was not easy.

At this time, Han Changlin also noticed that on the rock near the sea not far in front of those people, there was a red bead hanging in the void, and the crocodile demon beast was still desperately trying to get close to the red bead while attacking a few people.

What made Han Changlin feel even more strange was that he was so far away that he could even smell the fishy smell emanating from the red bead.

This made Han Changlin's face show a deep expression, and after a while, Han Changlin's mouth opened, and a Qingyan sword suddenly shot out, and after flying thousands of zhang away, it had already turned into a shocking blue and red rainbow, falling from the sky.

The crocodile demon beast instinctively felt the danger, and the cold light in its two small eyes was shining, and it suddenly caught the blue and red sword light falling from the sky, but it didn't have time to dodge at all, and was slashed directly on the back by the sword light.

A terrible roar came out, and the incomparably hard scales of this crocodile demon beast were easily cut in front of Han Changlin's Qingyan Sword like tofu, and the crocodile demon beast was also directly cut in two by a sword, and a small ice cube condensed at the incision, but not a trace of blood flowed out.

The five of them looked at everything that happened with horror on their faces, watching Han Changlin fall from the sky and land next to the crocodile demon beast.

The five of them were foundation building monks, and just from this person's means and control, they also understood that the person in front of them was a Jindan monk, and the first of them, a long-faced monk in his thirties, came to Han Changlin with a little caution.

"Sha Haoqian, a disciple of Liumu Island, a junior of Liumu Island, visited his seniors."

After this person met Han Changlin, the other four people also came to Han Changlin one after another and bowed down, but they looked at Han Changlin with an expressionless face, and they were also a little apprehensive in their hearts.

The person in front of him doesn't look like the Demon Dao Monk of the Six Extremes Demon Palace, and it may not be unfavorable to the five people, but in fact, it is not the Demon Dao Monk who will do those murderous and treasure deeds, many Immortal Dao Monks are dignified on the surface, but they have done a lot of bad things behind their backs, and there are many such people.

Han Changlin has also cultivated step by step from the bottom to the point where he is now, seeing their expressions, how can he not know what they are worried about.

"You don't need to worry, I don't have any thoughts against you, but I have something I want to ask you, and you must answer honestly."

Han Changlin said lightly, but the Qingyan Sword surrounding him did not have the slightest intention of putting it away.

Hearing what Han Changlin said, the tense nerves of several people relaxed slightly, but their vigilance did not let go.

"What did the seniors ask? As long as the younger generations know, they will definitely not hide it. ”

The long-faced monk was obviously the head of the five, and immediately replied respectfully when he heard this.

"What is this? What is it for? ”

Han Changlin pointed to the blood-red bead hanging in the air and asked.

Seeing that what Han Changlin was asking about turned out to be this thing, the long-faced monk immediately replied respectfully:

"This is a demon summoning bead, which can attract second-order demon beasts within a radius of a hundred miles, so that the juniors can wait for the rabbit and wait for the demon beasts to enter the ambush set by us."

"Demon Summoning Beads?"

Han Changlin still didn't have any expression on his face, but his heart moved, and he said lightly:

"Where did this Demon Summoning Bead come from and how was it refined? Is it possible to attract higher-order third-order demon beasts? ”

When the long-faced monk heard this, he already understood the purpose of the senior in front of him, although he was a little strange in his heart, this demon bead was not a rare item in the Great Zhou, and the person in front of him didn't know it, which was really a bit unreasonable, but after a little thought, he classified Han Changlin as those immortal cultivators who practiced in retreat all the year round, this kind of person generally has a deep background, and he is not worried about the lack of resources at all, as long as he cultivates in retreat all the year round, the realm will naturally come naturally.

"What the seniors asked, the juniors naturally knew everything, this demon bead is actually very easy to refine, and the material of the demon bead is also divided into four categories, namely the first order, the second order, the third order and the fourth order, which correspond to the first-order, second-order, third-order and shape-shifting demon beasts.

"The first three orders of the Demon Summoning Bead can be bought in the Wanzhang Yuanfang Market in the Black Abyss Sea, but the Demon Summoning Bead that I just bought is not useful, in fact, the Demon Summoning Bead is just the material itself, it can really be used, and the essence blood of the demon beast must be injected into it."

"Through the art of blood alchemy, to refine the demon beads, in this way, the demon beads can exude bloody aura, and this is also the favorite thing of demon beasts, so as to attract demon beasts hiding in the depths of the sea to come."

"I see."

When Han Changlin heard this, he finally understood, and at the same time figured out why he had searched the sea for so long, and he didn't find the reason why the demon beast was found.

In fact, most of the demon beasts usually hide in the deep sea, and rarely come out, of course, if they find the figure of the Terran monk, they will also burst out of the water to attack, but more are lurking in the deep sea all year round, dormant and dormant.

The Terran monks have been operating this Ten Thousand Demon Sea for I don't know how many years, and they have also summed up some means to attract these demon beasts, and the demon beasts themselves will fight each other, so they are very sensitive to the bloody qi, and the demon summoning beads refined through the blood sacrifice of the demon beasts are even more fishy to the extreme.

But this kind of fishy qi is also divided into different types, for example, the demon summoning beads refined by the essence blood of first-order demon beasts usually only attract first-order demon beasts, unless the bloody qi is too strong, there may be a certain probability of attracting second-order demon beasts.

In the same way, the second-order demon summoning beads can only attract second-order demon beasts, and so on, the third-order demon summoning beads can only attract third-order demon beasts.

"If the seniors want to hunt the second-order demon beasts, the juniors are willing to give this second-order demon summoning bead to the seniors."

The long-faced monk saw the uncertain look on Han Changlin's face, and said flatteringly.

Hearing this, Han Changlin waved his hand and said:

"I'm not interested in second-order demon beasts, and please tell me the location of Wanzhang Yuanfang City."

"What is recorded in this jade slip of the predecessor is a map of the nearby sea area, and there is a location of Wanzhangyuan in it."

When the long-faced monk heard this, he immediately took out a jade slip from the bag on his waist and respectfully handed it to Han Changlin.

Han Changlin stretched out his hand to take the jade slip, and his divine thoughts probed into it, and he found the location of Wan Zhangyuan in an instant.

The storage ring on his hand flashed, and a small cloth bag appeared in his hand, and Han Changlin casually threw the cloth bag to the long-faced monk.

"Here are a hundred lower-grade spirit stones, which can be regarded as my purchase of this nautical chart jade slip of yours."

After speaking, Han Changlin turned into a thick blue and red light, shot into the distance, and disappeared without a trace in the blink of an eye.

"Brother Sha, this person is a Jindan real person, and he doesn't even know the existence of the Demon Summoning Bead? Is it really weird? ”

An ordinary-looking nun said to the long-faced monk.

"This person is either an ascetic, or he is not from our Great Zhou at all, this is not strange, Yunlan, you hurry up and put away the demon summoning beads, after we take this three-eyed cold water crocodile, we have to breathe first, if there is another second-order high-level demon beast, we can't bear it."
