Many people were taken aback by Lin Xiao's question, the refining method of this mustard seed space and secret realm is not a very mysterious thing, but all the major sects, or the sects that think they have strength, will study it, but these words came from the mouth of a little monk from Nanzhou, so there are some surprises.

It's as surprising as a beggar stopping a passerby and telling him that he knows a way to make 10 million.

"Lin Daoyou, the rule of the exchange meeting is that each person can only ask once, don't you think it's more appropriate to ask other questions?"

"Thank you Ye Daoyou, but I think this question is good, this ring space magic weapon of your sect makes Lin very interested, I want to learn a little first, and see if I can refine one later, and then I can go out to travel without eating and sleeping in the open."

"This Lin Daoyou, I don't think you look like a whimsical person, do you know how precious this ring space is, even if you are a master of three professions in one, it is not enough, in the world of cultivating immortals, even in the middle continent, there are no more than ten sects that can afford to refine this kind of ring space, Tiangongmen is the only one among the second-rate forces, this is still the ancestor of Tiangongmen can only refine it by chance"

"I understand, thank you for your kindness, in fact, Lin didn't say that he would refine it now, he just wanted to open his eyes, if it's inconvenient, then forget it"

Lin Xiao arched his hand, he naturally knew the preciousness of this ring space, it can be said that now that he sells the entire martial country, he can't make up one-tenth of the cost of this mustard seed space, but Lin Xiao has confidence in himself, he can't refine it now, and he may not be able to do it in the future.

"It's okay, since Lin Daoyou wants to know, then I'll just talk about it, the refining of mustard seed space magic weapons is mainly divided into two types, the first is a treasure containing space laws, such as the Void Stone, the refiner refines its space laws and fixes them, so as to form a fixed space, and finally refine them into treasures.

The second method is to have the strongest person cut the space, and then use the supreme divine power to refine the space fragments to form a one, independent space, but this kind of strongest person can only do it with the strong person of the ninth realm.

This is the outline of the mustard seed space, the secret realm and the mustard seed space are roughly the same, to say that the difference is that one is fixed, the other is mobile, and the difference lies in the spiritual veins.

The spiritual veins of the secret realm are very easy to explain, where does the mysterious qi of the secret realm come from, the spiritual veins come from, how the spiritual veins produce the mysterious qi in the secret realm, and it is good to pull it in, so pulling the spiritual veins is the key to refining the secret realm.

As for the mustard seed space, it is not connected to the spiritual veins of a certain place, it is necessary to cultivate the spiritual veins in the space, and the difficulty of cultivating the spiritual veins in the mustard seed space is several times more difficult than in the outside world, how to cultivate it, then don't ask me, I am just a refiner, I can only refine weapons, and the rest will not.

Now let me talk about some of the characteristics of refining mustard seed space, the mustard seed space is different from ordinary magic weapons, the main thing is that this already involves the law·····"

The person on the stage did not refuse to explain because of Lin Xiao's words, but explained it more clearly, very organized, and Lin Xiao listened word for word.

An hour later, the explanation ended, and another person continued to ask, but Lin Xiao was thinking deeply about the question just now, this mustard seed space and secret realm, it is really not that simple, even if he grabs the secret realm at this time, how to bring it back when the time comes, how to install it in the mountain gate of the Heavenly Saint Sect, it is also a big trouble.

Thinking of this, Lin Xiao was suddenly shocked, fortunately he participated in this exchange meeting and knew these things, otherwise he would have rashly robbed the secret realm of the Assassin God, and he would not be able to install it at that time, wouldn't the system be upgraded? If the system could not be upgraded, then how could Lin Xiao resist the revenge of the Assassin God, isn't this the way to die?

Lin Xiao hurriedly retracted his mind and continued to listen to the explanations of the masters, the refiners who could explain on the stage were at least fifth-order high-grade or sixth-order level, which was enough to be called a master.

After a round of questions, three days have passed, but fortunately, everyone is a high-level monk, and it will not affect them at all if they don't eat or drink for a few days.

However, after asking the question, Ye Jiuji still let everyone rest for a long time, and let people send all kinds of food, spiritual food and fruits, so that everyone can recover their minds and combine what they have learned in the past three days.

Half a day later, the last and most important part of the exchange meeting began, that is, the exchange of treasures, Ye Jiuji asked everyone to sit in a circle, and then selected one person, let people go to the middle, take out their own treasures, and say their own exchange requirements, everyone can transmit to their secret words, or they can make a public offer, how to choose, it is up to him to decide.

"Ye Daoyou, you have contributed a lot to this exchange meeting, so you can start."

"Haha, then the nine machines will not shirk, Ye Mou took out this time in exchange for a Divine Stone outside the sky, this Outer Heaven Divine Stone is from outside the sky, the essence after it is burned out, it contains terrible fire attribute rules, after the appraisal of the elders of my sect, it is not lower than the seventh order, I want to exchange it for the Five Elements refining material, but it cannot be lower than the sixth order, the value is not enough, you can exchange it for more than one, or make up for part of the difference"

"Ye Daoyou, can you let us take a look at this Outer Heaven Divine Stone?"

"Of course"

Soon, Ye Jiuji's Outer Heaven Divine Stone was uploaded in everyone's hands, everyone is a refiner, and they also have the ability to identify treasures with one hand, which is enough to see that this Outer Heaven Divine Stone is not fake, it is very precious.

Everyone also quoted one after another, and in the end, the Outer Heaven Divine Stone was replaced by a spiritual light monk, and no one knew what was changed, he took a storage bag, but looking at Ye Jiuji's expression, he should be very satisfied.

When it was Lin Xiao's turn, Lin Xiao walked to the middle and took out a set of short-range teleportation arrays, to exchange them for empty spirit stones or other spatial treasures, if there was a secret method on how to pull the spiritual veins to the secret realm.

This short-range teleportation array was exchanged by Lin Xiao from the system mall, and it was also a treasure that Lin Xiao felt could get in the mall, and it was very unrefusable.

"Lin Daoyou said to do it, and it is really resolute, the old man has an empty stone here, which has not been cut, but it should not be less than the size of five standard empty stone stones, the standard size set by the two sects of Yunxiao and Tianxiao is really disgusting."

"Although my teleportation array is short-range, it also has more than 30,000 miles, and the port of transmitting twenty people at a time, the empty stone of the predecessor is still a little worse."

"Lin Daoyou, the Empty Immortal Stone can be bought in many places, but the traction secret method you want is not something anyone can sell, this is exclusive to the big forces, but it is a coincidence, there is such a set of secret methods in the next hand, I don't know how Lin Daoyou chooses"

Soon, someone made a bid, Lin Xiao naturally chose that secret method, although this secret method is not worth much after the system is upgraded, but this system is not upgraded, Lin Xiao naturally chose the secret method.

After the delivery is clear, the next one goes up, just one by one, Lin Xiao has also shot repeatedly, he has reported the level of refining, formation, and talisman making three professions before, which in addition to boasting of his own level, is the standard of financial resources.

After all, coupled with alchemy, it is called the four arts of cultivating immortals, these four skills are the most profitable among the hundred arts of cultivating immortals, and Lin Xiao accounted for three of them at once, so it is normal to show that he is rich in wealth, and he will not arouse the suspicion of others.

In one day, the exchange of treasures was over, Ye Jiuji let people go to the banquet again, everyone ate and drank for a long time before withdrawing, this time Ye Jiuji and several other monks of the Tiangong Sect also benefited a lot, especially the deep connections, which is the most important.

After the exchange meeting, Lin Xiao settled down in the city and studied the secret technique in exchange, and it took three years to have a little experience.

This secret realm pulls the spiritual vein, and really needs the assistance of the earth master, and the earth master needs to change the direction of the spiritual vein, and then the spiritual vein is pulled into the secret realm by a person who is a superb cultivator, so that it can be successfully brought back to life, so that a new spiritual vein can be generated in the secret realm, and after thousands of years, the spiritual veins in the secret realm will be independent.

With this secret technique, Lin Xiao was a little relieved, and then Lin Xiao disguised himself many times, went to various stores in the city to search for things that were not entered in the system, and gained a lot of points.

At the same time, the friendship with Tiangongmen is also getting deeper and deeper, Lin Xiao is not ashamed to ask, banquets Ye Jiuji and others many times, and then takes the opportunity to ask for some refining things, and his alchemy skills are not hesitant to be public, and the communication between the two sides is very pleasant.

The high-level alchemy of Tiangongmen has made Lin Xiao's refining level soar, and in ten years, Lin Xiao's alchemy has broken through the fifth-order middle grade, and the magic weapons refined are extremely sophisticated, which is no longer inferior to the level of Tiangongmen's disciples.

After staying here for more than ten years, Lin Xiao left in a hurry, if Lin Xiao was not mistaken, the Dao Ji Dan of the sect was about to mature, and the true spirit grass of the Qianluo Kingdom was not a few years away, Lin Xiao had to go back to the town.

It took half a year for Lin Xiao to return to Bai Xueju in Xuanyue City, and after meeting, he gave Li Muxue three storage bags, all of which were purchased by Lin Xiao when he was harvesting points at Tiangongmen, and Lin Xiao couldn't use them in ninety percent, so he had to sell them in Xuanyue City.

"Master, what are you doing here, why are there so many disorganized things, many things look like waste"

"You don't care so much, just sell these things, I wrote the price, this is the reserve price, no less than this price can be sold, and I will give you a fifth-order high-grade magic weapon, this is the sword I bought, the name is Qinggang"

"This sword is good, the balance of yin and yang is well handled, it suits my Kurong Jue, thank you Master"

"Well, I've been away for more than ten years, how is your alchemy?"

Lin Xiao nodded, what he was most concerned about was the matter of Lingming Dan, as long as he controlled this, the Heavenly Saint Sect would be equivalent to joining the monopoly system, and he would really make money in the future.
