Of course, for the fourth-order mature spirit grass and refining materials, they basically can't be seen in this relatively low-end market.

But there are no absolutes in everything, and the fourth-order mature spirit grass and refining materials may not be visible, but the seedlings of the fourth-order spirit grass that some immortal cultivators pick by chance will still appear occasionally.

The medicinal age of the fourth-order mature spirit grass must be at least seven or eight hundred years old, which leads to the fact that if an immortal cultivator discovers a seedling of a fourth-order spirit grass in an inaccessible place, he will basically not continue to raise it, and will pick it again when it is mature.

Nine times out of ten, they will be directly picked back and sold at a lower price, for this kind of fourth-order spirit grass that is not enough in the year, it is not all useless, in the immortal cultivation world, some alchemists have specially researched a downgraded spirit pill.

For example, if a hundred-year-old fourth-order spirit grass wants to refine a fourth-order spirit pill, it is naturally impossible, but an alchemist can refine a second-order spirit pill according to the concentration of spiritual energy contained in the spirit grass and the age of the medicine.

The medicinal power of this improved version of the elixir is much better than that of the ordinary second-order elixir, and even because the aura in it is relatively condensed, this kind of second-order elixir can improve a small amount of cultivation even if some foundation building Great Perfection cultivators take it.

In Han Changlin's view, this kind of behavior of destroying some tyrannical things is also a kind of use of immature high-grade spirit grass, which avoids waste, and this also leads to the seedlings of high-level spirit grass on the market are very precious, and basically as soon as they appear, they will be bought by some alchemists.

And the third-order spirit grass does not have this effect, the immature third-order spirit grass, the degree of condensation of the spiritual energy is not as good as most of the second-order spirit grass, it is not enough to refine the spirit pill at all, even if it is barely refined, at most it is the level of the ordinary first-order spirit pill, for immortal cultivators, it is really a bit of a chicken rib.

It is that those third-order immature spirit grasses that can produce seeds or grow with cracked roots can still be sold at a relatively good price, after all, they can be used for cultivation, as for those third-order immature spirit grasses that are born from the aura of heaven and earth, on the contrary, no one cares about them, and it is difficult to sell.

Han Changlin soon came to the Fang Market in the east of the city, and under his eyes, Han Changlin quickly estimated the area of this Fang Market, which was about ten miles, and it was already full of people at this moment, at least tens of thousands of immortal cultivators shuttled among them.

In this Dongfang City, according to the cultivation of the stallholders, it is also obviously divided into three categories, the outermost part is naturally a large number of Qi refining period monks, and they set up stalls more casually, some people directly pull a piece of cloth on the ground, put things on it, and a stall will become.

And near the middle, there are some small counters, on which are placed items for sale, and in the counter, there is a foundation building stage cultivator who closes his eyes and recuperates.

At this time, Han Changlin saw at a glance that in the center of Fang City, there were several rows of extremely exquisite wooden houses, this small wooden house had no door, and it was very open, and he could vaguely see the counters full of items placed inside.

At the same time, Han Changlin saw rows of female cultivators, neatly arranged around Fang City, there were at least dozens of people, most of them were low-level cultivators above the seventh or eighth level of qi refining, but the dozen or so female cultivators led by them were in the realm of the foundation building period.

Moreover, Han Changlin was still in the four corners of Dongfang City, and saw four wooden houses, these four wooden houses did not have doors like in the middle of Fang City, but the doors were closed, and Han Changlin could vaguely sense the amazing spiritual pressure emanating from the wooden houses.

Han Changlin naturally understood that these people were all guards stationed in this Black Rock City by the Imperial Water Palace, and they were responsible for maintaining order, and of course, they were also collecting booth fees for better management.

This is actually a very normal thing, the reason why the sect was born is to occupy more immortal cultivation resources through the form of the sect, in this big week, whether it is the Imperial Water Palace, the Six Dao Kui Demon Palace, or the Five Elements Alliance, they are all such organizations.

The entire Great Zhou, except for a large area of sea in the north, is basically under the control of these three major forces, and within the respective scopes of these three major forces, whether it is Xiancheng or an island, it is basically firmly controlled by these three major forces.

With the help of the massive number of monks in the Great Zhou, these three major forces also made a lot of money, Han Changlin just thought about it, and he could clearly understand that these three major forces were absolutely rich, and the rent fees collected every year alone did not know how much.

And for the high-level of these three major forces, they can basically get a massive supply of immortal cultivation resources without leaving home, which is no wonder, these three major forces have controlled hundreds of millions of miles of sea in the Great Zhou for hundreds of thousands of years, and they are still as calm as a mountain and cannot be shaken.

After thinking of this, it also made Han Changlin understand the importance of the forces behind him, in the final analysis, the immortal cultivation world is a huge food chain, and standing at the top of this food chain are naturally those high-ranking elders of the major sects, as well as the great cultivators who may exist behind the scenes, and the great cultivators who may not exist or even transform into gods.

In this realm, after the immortal cultivator broke through the Great Perfection of the Yuan Infant and entered the stage of transforming into a god, it seemed that he had disappeared without a trace, and the cultivator never seemed to show his form.

And Han Changlin knew that the Transformation Stage was also the same as the Yuan Infant Period, only by cultivating to the Great Perfection of the Transformation of the Gods could he soar and enter the ethereal upper realm, from the early stage of the Yuan Infant to the Great Perfection of the Yuan Infant, this process was enough to make more than ninety percent of the Yuan Infant monks out of reach.

Then from the early stage of the transformation of the gods to the great perfection of the gods, isn't it several times more difficult, although the longevity of the transformation monks is far more than that of the yuan infant monks, but if you want to cultivate to the transformation of the gods to the great perfection, in Han Changlin's opinion, it should be an almost impossible task.

It was Han Changlin who had also guessed that these powerhouses who had entered the god transformation stage were probably busy cultivating and breaking through the realm, and they simply did not have the time and interest to stir up the disputes in the immortal cultivation world.

After all, for them, everything can't be compared to Ascension, and these god transformation bosses are at the top of the food chain in the Immortal Cultivation Realm, so they don't need to consider the shortage of resources at all, so there is no need to show up and go around for adventure and training.

Of course, Han Changlin knew that he didn't have such treatment, so he threw these distracting thoughts out of his mind, and Han Changlin walked into the market.

In order to avoid trouble, Han Changlin hid his aura through the Yi Ling Transformation Secret Technique, and only revealed the cultivation in the middle stage of foundation building, and this cultivation monk can be said to be a big grasp in Dongfang City, and it will not attract attention.

The quality of the Fang City in Black Rock City is much higher than what Han Changlin has seen in several large immortal cities in Zhao Kingdom, this is of course the monks in the Fang City of Black Stone City, not only has a large number of immortal cultivators in the foundation building period, but even has a lot of Jindan monks.

On the other hand, perhaps because this Black Rock City is connected to the Jinxia Immortal City in the endless open sea, the immortal cultivation resources sold are also more rich and diverse, whether in terms of quality or level, they are much higher than the Fang City of Zhao State.

Even Han Changlin did not doubt that there were not a few Jindan monks like himself who were hidden cultivators and mingled among the many immortal cultivators.

Entering the Fang Market, Han Changlin began to wander around, and after shopping for half an hour, Han Changlin found that most of the materials in this Fang City were refining tools and talisman making materials on some demon beasts, which also led to the number and types of magic weapons in the entire Zhao Kingdom far exceeding that of the Zhao Kingdom.

Moreover, a large number of talisman pens made of demon beast hair, spirit ink made of demon beast essence blood, and rune paper refined from demon beast skin make a lot of spirit runes sold in the market.

However, these talismans were basically used by first- and second-order low-level cultivators who were suitable for qi refining and foundation building, and for Han Changlin, they were not eye-catching at all.

Originally, he also wanted to buy some essence blood of emperor-level demon beasts, so that he could go back to refine blood alchemy, but after shopping around, he found that there were a lot of demon beast essence blood sold in the market, but basically it was the essence blood of mortal-level and true-level demon beasts, and as for the essence blood of emperor-level demon beasts, there were also a few stalls for sale.

But firstly, the quantity is relatively small, and secondly, the price is more expensive than that in the commercial bank, and after thinking about it, Han Changlin decisively gave up.

Later, while wandering around, Han Changlin bought a few more charts around Jinxia Immortal City, and after he understood that this Great Zhou was divided into the Inland Sea Burning Immortal Sea and the Endless Outer Sea, he was also full of curiosity about the Outer Sea.

This may be a common problem of immortal cultivators, full of desire to explore some unknown places, the endless open sea, is the area where human monks and endless demon beasts meet, human monks hunt demon beasts, to collect all kinds of immortal cultivation materials.

For demon beasts, it is not by hunting humans to satisfy their appetites, and after devouring human monks, they can also greatly improve the path of demon beasts.

Walking around the periphery of this city, Han Changlin did not find any trace of the fourth-order immature spirit grass, but this was also in his expectation, the fourth-order spirit grass, even if it was immature, was very rare, and it was not something that could be bought if he wanted to.

"Huh?"

Han Changlin, who was hanging out, suddenly let out a low cry of surprise, and his body that was about to move forward also stopped, turning his head to look at the stall next to him.

The owner of the stall was an ordinary-looking man who looked twenty-seven or eighteen years old, looking a little haggard, with stubble almost all over his chin, and in front of his stall, only a few ancient books were placed.

The covers of these ancient books are yellowed, and there are some damages in some places, and there are a few immortal cultivators, after seeing these ancient books, most of them choose to stop, take one of them, and turn a few pages slightly.

And after reading a few pages, I basically put it down, shook my head, and turned away.

And the ordinary-looking stall owner, whenever someone picked up a book to read, showed a hint of hope on his face, and after others left, his eyes showed a little loss.

The reason why Han Changlin stopped was because one of these ancient books had the big characters [Detailed Explanation of the Mystery of the Formation] written on the cover.

For a long time, Han Changlin has always been very interested in the way of formations, and he also wants to study it carefully.

However, at that time, he was only a foundation building monk, and his longevity was only more than two hundred years, and Han Changlin at this stage spent all his time on cultivation, and he was still worried that he would not be able to enter the Jindan stage at the best age for cultivation.

Naturally, there was no extra energy and time to delve into the formation, and after carefully comprehending the [Yantian Immortal Sutra], Han Changlin obtained the refining method of the Qingyan Extreme Thunder Sword, as well as the driving formula of the sword formation.

But it is one thing to be able to use it, and whether there is a deeper understanding of the truth in it is another matter, and in this Yantian Immortal Sutra, there is only the method of arranging the formation, as well as the changes and emergency measures against the enemy, and there is no detailed explanation of the mystery of the formation.

After learning about this, Han Changlin secretly decided that if he had the opportunity in the future, he would buy a book on the inner truth of the formation and carefully comprehend it.

In fact, many immortal cultivators know that only by understanding the deep mystical truth of the formation, can the envoy be handy, flexible in change, and more importantly, whether it is an adventure outside, or a retreat cultivation, it is indispensable to contact some forbidden methods, if you don't understand the profound truth of the formation, if you want to rely on brute force to crack it, it is basically impossible.

Thinking of this, Han Changlin picked up the [Detailed Explanation of the Mystery of the Formation], opened the cover, and looked at it carefully.

And the ordinary-looking decadent man saw that Han Changlin seemed to be interested in his book, and his eyes once again showed an expression of hope.

After reading the tea kung fu, Han Changlin closed the cover, picked up a copy of [Detailed Explanation of the Formation Change Method of the Nine Palaces Jue], and after reading it for a while, Han Changlin closed the book in his hand, with a thoughtful expression on his face.

Han Changlin glanced at the man, saw his satisfied and hopeful gaze, and asked lightly, "How do these two books sell?" ”

Han Changlin pointed to the book on the stall [Detailed Explanation of the Mystery of the Formation], these two books are indeed introductory books on the formation in Han Changlin's opinion, and the content in them is easy to understand, and the author of this book also listed a lot of examples to simplify the content of the book.

And more importantly, through these two books, Han Changlin understands that the person who can write these two books should be a famous formation expert.

"A hundred lower-grade spirit stones per book."

When the decadent man saw Han Changlin asking about the price, he immediately said with anticipation on his face.

Hearing this price, Han Changlin frowned slightly, not that he felt that the price of these two books was expensive, but that they were too cheap, most of these formation classics were written by people who had studied the way of formation and had certain achievements.

Not to mention the content, just the writing process is also a time-consuming and labor-intensive thing, of course, the explanation of the way of the formation can also be recorded through the jade slip, which is the easiest and most convenient way for immortal cultivators to record the mantra of the exercises.

These two books not only explain the inner truth of the formation in detail, but also depict a lot of formation graphics, and list in detail the door of life, the door of death, and the method of their transformation of life.

"If Daoist friends are too expensive, ninety pieces of lower grade spirit stones, this price is already the cheapest, in order to write these few formations, the family master has already ....."

Seeing Han Changlin's expression, the decadent man thought that Han Changlin was too expensive, and he couldn't help but show a look of great urgency on his face, and the price also dropped from one hundred lower-grade spirit stones to ninety lower-grade spirit stones.

"You're saying that you didn't write these formation books yourself?"

After hearing this, Han Changlin asked in surprise.

"Although I also have a rough understanding of the formation, but when it comes to writing the formation classics, it is far behind, these books are written by the family teacher, the family teacher was plotted by the enemy sixty years ago, and has been bedridden, in the past few decades, in order to treat the family teacher's injuries, almost all the savings in the sect have been spent, and more than a dozen brothers have also left, and now only the next person remains."

"And in order to maintain his vitality, the family master was seriously injured, so he wrote these formations and let them be sold in the next place, so as to earn some spirit stones, so that he could buy medicine for the master and her old man."

"I see."

When Han Changlin heard this, he finally understood, he couldn't help but feel a little interested in the master of the decadent monk, in his opinion, he could write such a mystical formation script, and he should not be unknown in the way of the formation.

"I bought all these array law books, but Han has one condition, that is, to take Han to see the commander."

Han Changlin opened his mouth and said.

After hearing that Han Changlin had bought all the formation books in his stall, the decadent man's face was full of surprise, but when he heard the second half of the sentence, his face showed a hesitant expression.

"Daoist friends don't have to worry, Han has no malicious intentions, it's just that Han has recently been contemplating a set of sword formations, and there are a lot of incomprehensions in it, so he wants to ask the master for advice."

What Han Changlin said was half-true and half-false, what he said was true, but the real purpose was not all to ask for doubts in the cultivation sword formation.

The decadent man did not agree, but looked at Han Changlin, showing a thoughtful expression, he thought about it, he and the master have been dependent on each other for decades, and now they are even more apprentices, because the master is seriously injured, he can't stay away from going out to experience and earn spirit stones.

Now in the past few years, he can only rely on the master to compile some formation classics, and every day he comes to Dongfang City, selling one or two classics to earn spirit stones, to grab a few elixirs for the master, and suppress the injury.

The decadent man has long lost confidence in the future of his cultivation, and only hopes to accompany his master, send him to old age, and then find a quiet place for the rest of his life.

Since the person in front of him proposed to see the master, this made him a little worried, whether this person was the master's former enemy, and if he rashly brought it back, it would be tantamount to luring the wolf into the house.

And if he refuses, this person walks away, then the master's elixir today will be gone, and he will be in a dilemma for a while, and he doesn't know how to answer.

Seeing the change in the expression on the decadent man's face, Han Changlin could also roughly guess the scruples in his heart.

"The reason why Han wanted to see the commander was indeed because Han was very interested in the way of the formation, and through these manuscripts, Han guessed that the commander must be a master of the formation, so he wanted to talk to him, so as to humbly ask for the mysteries of the formation, and there was no other plan, if the Taoist friends didn't believe it, Han was helpless, so he took his leave."

After speaking, Han Changlin turned around and wanted to leave.

"Fellow Daoists, slow down."

The decadent man opened his mouth and shouted to Han Changlin, his heart was horizontal, in his opinion, if it is not opened again, whether the master can survive these few days is a matter of two words, if this person really just asks the master for some formation methods, it is okay to lead him to see the master.

At least with these spirit stone incomes, the breath of the master can last for some time.

Thinking of this, the decadent man's face showed a bit of determination: "I agreed." ”

Hearing this, the star ring in Han Changlin's hand flashed slightly, and a burlap bag appeared in his hand, which looked heavy and bulging, and he casually threw the bag in his hand to the decadent man.

"Here are five hundred lower-grade spirit stones, buy these two formation books." put away the [Detailed Explanation of the Mystery of the Formation] and the [Detailed Explanation of the Formation Change Method of the Nine Palaces], and then looked at the decadent man quietly.

The decadent man was slightly stunned, put away the spirit stone, and then didn't say anything, and began to put away the stall, and after the tea, the decadent man had already cleaned up, and then said to Han Changlin:

"Fellow Daoists, please come down with me."

Han Changlin nodded, motioning for the decadent man to lead the way.

Following the decadent man through a few streets, the two entered the large private houses in the south of the city, and saw the rows of dwarf wooden houses on both sides, Han Changlin's brows couldn't help frowning slightly.

The decadent man was an immortal cultivator in the early stage of foundation building, and he actually lived with a group of ordinary people, which made Han Changlin sigh in his heart.

At the same time, Han Changlin also had a good impression of this decadent man, a foundation building monk was willing to live such a depressed life in order to take care of his seriously injured master, just this filial piety, Han Changlin also sighed to himself.

Passing through the narrow streets, the south of the city is the residence of mortals in the immortal city, and for mortals, they need to eat, drink, and Lazar, which causes the entire area in the south of the city to be full of peculiar smells, which makes Han Changlin frown slightly.

It was about a meal before the decadent man stopped in front of a very dilapidated room.

"Fellow Daoist, come in."

The decadent man made a gesture of invitation to Han Changlin, and then took the lead and walked in.

Han Changlin followed, and after entering the yard, he found that the yard was not small, about an acre, and it was full of foot-high weeds, which had obviously not been taken care of for a long time.

As soon as he entered the courtyard, Han Changlin heard a violent coughing sound coming from the room in front of him, as if he heard movement in the courtyard.

"Is Huzi back?"

A somewhat hoarse and visibly airless voice came from within.
