The only thing about Su Xiaofan's personal space that is not as good as a small cave is that the space inside the body cannot be displayed and used for living and resting.
"You can just refine a small cave, but there is no need to integrate it into the body."
Su Xiaofan thought for a while and came up with an idea. He only needed this small cave to be able to carry it with him, and then use it to rest outside.
As for storage, the space inside Su Xiaofan's body is more than a hundred times larger than that of a small cave, so there is no need to put the cart before the horse.
"Huh? To build a cave residence, you need to use spiritual wood?"
Su Xiaofan noticed one of the requirements, which was to use spirit wood to carve formations on it.
Ordinary wood is not good enough. Even the Xumi formation cannot be carved on it. Naturally, the cave cannot be retracted or enlarged.
"This thing seems easy, but it is very troublesome to make."
After Su Xiaofan read the methods and steps for making a small cave dwelling, he couldn't help but shake his head and smile bitterly.
Su Xiaofan's cultivation level is sufficient, and he also has the strength to seal a small space in the turbulent space, so there is no problem with this.
But if the cave structure with the formation engraved on it cannot be combined with the space, naturally this small cave residence will not be able to take shape.
What Su Xiaofan is lacking now is materials. There are some messy alloy materials in the space inside his body, but those things cannot be used in this cave.
"Forget it, pay more attention in the future and collect these materials when you encounter them."
Su Xiaofan shook his head, put away the jade slips used to make the small cave, and then took out the jade slips used to refine the secret door.
Compared to a small cave, that thing is not a necessity, it just makes Su Xiaofan's life in the starry sky more comfortable.
But the secret door is something Su Xiaofan attaches great importance to.
According to what Venerable Huo Tian said, the Great Secret Realm seems not to be in the universe, and the materials and resources produced in it are all needed by cultivators of Immortal Lord, Golden Immortal and above.
Although the cultivation system is different, Su Xiaofan does not need the resources of the cultivator very much, but Su Xiaofan needs the repair value.
Many of the cultivator's materials and resources can be converted into repair values. The more precious they are, the more repair values they can be converted into, so Su Xiaofan is now coveting the great secret realm.
“Damn it, where can I find so many materials?”
When Su Xiaofan saw the materials needed to refine the secret door, he couldn't help but be stunned.
There were actually thousands of materials listed in the jade slip, and Su Xiaofan had never even heard of 99.9% of the materials.
"No, I have to ask Venerable Huo Tian for a book that specifically introduces the treasures and materials of heaven and earth, otherwise I won't recognize it even if I see it."
Su Xiaofan gave a bitter smile and continued reading. He already had the basic materials for refining the secret door, but Su Xiaofan didn't want to refine an ordinary secret door. If he wanted to refine it, he would refine it with the best.
The jade slips given by Venerable Huo Tian were introduced in great detail, and the quantities required for each material were also listed one by one.
Su Xiaofan's expression slowly softened, because he discovered that among the thousand kinds of materials, more than 900 were not needed very much, they were all auxiliary or additive-like things during refining.
There are only three materials that are in greatest demand. Whether it is quantity or quality, the more, the better, the better.
The first is the Yuan Stone. It is introduced in the jade slip that the Yuan Stone is produced in the Yuan Stone veins in the Great Secret Realm.
To refine the secret door, you need middle-grade or above Yuan Stone, which costs at least 3,000 yuan. The more quantity and quality, the better. There is no upper limit.
If the secret door can be refined with top-grade yuan stones, the distance that the secret door can teleport is at least a hundred times that of the secret door refined with medium-grade yuan stones.
Yuan stones are not very rare in the Great Secret Realm, but all cultivators, including powerful cultivators, have a need for Yuan Stones.
The output of Yuanshi veins is not large, and usually the Yuanshi in the great secret realms that have been developed have been mined out long ago.
Yuan Stone is also the currency circulating in the Great Secret Realm. If some cultivators who meet in the Great Secret Realm want to trade with each other, they can use Yuan Stone to settle.
"Venerable Huo Tian is so particular..."
Su Xiaofan took the time to glance at the storage ring given by Lord Huo Tian, and immediately discovered the small pile of primeval stones.
Each piece of Yuan Stone is not big, only about the size of a thumb. It exudes an energy that Su Xiaofan has never seen before, and the small pile is exactly three thousand pieces.
Su Xiaofan knew without thinking that these three thousand Yuan Stones must be middle-grade Yuan Stones, and there was absolutely no way that Venerable Huo Tian would give the high-grade Yuan Stones to him.
In fact, Su Xiaofan didn't know that top-grade and top-grade Yuan Stones were really difficult to obtain, especially top-grade Yuan Stones, which could even be auctioned in some great secret realms, comparable to those treasures of heaven and earth.
The fact that Lord Huo Tian was able to find so many Yuan Stones for Su Xiaofan was already very valuable. If it weren't for the transaction between the two, Su Xiaofan wouldn't even know what the Yuan Stones were.
"There is no limit, grandma. If the secret door is refined with 30,000 pieces of top-grade Yuan Stone, can it be directly transmitted to the original galaxy?"
Su Xiaofan drooled when he saw the introduction in the jade slip. He decided to stop refining the secret door if he didn't get the top quality Yuan Stone.
Because after the secret door is refined, it will become your own natal magic weapon, and it will basically be difficult to improve its quality in the future.
Venerable Huo Tian also asked Su Xiaofan to be more cautious in the jade slips. It would be best to collect some top-quality materials before starting to refine the secret door.
"Yuan Shi, remember!"
Su Xiaofan firmly remembered the fluctuations emanating from the Yuan Stone in the storage ring in his mind.
This way of recording things is the most accurate and convenient. From now on, Su Xiaofan will not need to use his eyes to see, he can detect it as long as his mind touches it.
"Amethyst? What kind of material is this?"
Su Xiaofan saw the name of the second main material, which he had never heard of before, so he continued reading.
"It's not easy to find this thing either."
Amethyst is also produced in the Great Secret Realm, and it has appeared in all realms of the universe, but only a few people have gotten a little bit of it in the nebula, and the number is not very large.
Amethyst is actually not a crystal, but a mineral. It is the essence extracted from purple black iron. Usually, only three or five pieces of amethyst can be extracted from a purple black iron vein.
As for refining the secret door, you need at least a thousand pieces of amethyst, and the more the better, if there is no upper limit.
Compared with Yuan Stone, Amethyst is much rarer in the Great Secret Realm, and it is very difficult to find.
Because the purple black iron ore veins are almost indistinguishable from ordinary black iron ore veins.
There are many black iron ore veins in the Great Secret Realm, and the purple black iron ore veins are hidden among these ordinary black iron ore veins.
Many cultivators have been mining in the Great Secret Realm for many years in order to obtain amethyst, but the chance of being able to dig out the purple light black iron veins is very low.
Of course, this thing is the same as the Yuan Stone. As long as you have perseverance and find a large secret realm with more black iron veins, you can still get a thousand amethysts.
There once was a Golden Immortal Venerable who just wanted to make his secret door of higher quality, so he spent a lot of money to enter a great secret realm through someone else's secret door.
The Golden Immortal Venerable was very perseverant. He actually stayed in the secret realm with many black iron veins for half a million years and refined 3,000 pieces of high-quality amethyst.
Just imagine, it took half a million years of mining to extract three thousand pieces of amethyst. The output of this thing is so rare.
Of course, there are also some lucky Golden Immortal Venerables who accidentally stumbled upon a rich mine of purple black iron when they went to the secret realm for the first time.
The Golden Immortal cultivator only dug for a month and collected all the amethysts needed to refine the secret door. The remaining amethysts were sold at a good price.
"We have to find a way to find a great secret realm to enter, preferably one with rich resources."
After seeing these two things, Su Xiaofan was a little scratched his head. These things are not available in all realms of the universe or are very rare. The only way to get them is to go to the Great Secret Realm.
"Look for an opportunity to ask Venerable Huo Tian if you can enter the Great Secret Realm with him."
Su Xiaofan pondered for a long time, and it seemed that he only knew Venerable Huo Tian, a golden immortal with a secret sect. It seemed that he had to continue to pull out the wool.
Continuing to look down, Su Xiaofan actually knew the third material that was needed in large quantities, and he had obtained it before.
"Void Spirit Stone!"
Su Xiaofan did not expect that the last main material of the secret door would be the ethereal stone.
He had gotten a few pieces of this thing from his disciple He Lianxiong before, and later refined some pieces of storage equipment and gave them to his family, but now he doesn't have any pieces.
But even if there are, those ethereal stones are not suitable for refining the secret door.
According to the introduction of Venerable Huo Tian, the ethereal stone is also called the space spiritual stone, and it can be divided into four grades: upper, middle, lower and top quality.
If you want to refine the secret door, you need at least one hundred high-grade ethereal stones.
What Su Xiaofan got back then was just a low-grade ethereal stone. At best, he could only refine some storage equipment with little space.
High-grade ethereal stones are extremely rare, and they do not exist in the universe. However, compared to the above two main materials, ethereal stones are easier to obtain.
Because the ethereal stone is produced in the turbulent space, it can be entered by the Golden Immortal. Compared with the Immortal Lord, the turbulent space poses less of a threat to the Venerable.
So as long as you work hard and stay in the turbulent space for tens of thousands of years, you can still get a hundred high-grade ethereal stones.
Of course, one hundred high-grade ethereal stones is only the lower limit, and there is no upper limit.
The main function of the ethereal stone is to stabilize the secret door space.
The more ethereal stones used and the higher their quality, the more stable the space of the secret door will be and the farther the teleportation distance will be.
For example, the golden immortal whose secret door collapsed as mentioned before was anxious to refine the secret door and went to the Great Secret Realm because he was missing more than a dozen ethereal stones. He made do with more than 80 ethereal stones and started refining it.
The Golden Immortal was successfully refined and went to the Great Secret Realm, but after using it five or six times, the secret door collapsed when it was opened, and the Golden Immortal is still missing.
Therefore, the quality and quantity of the ethereal stone can be said to be the most important among the three main materials, because this thing is directly related to the life of the cultivator.
In addition, if more ethereal stones are used, more people can be teleported by opening the secret door at one time, which is a huge investment for the Golden Immortal.
You must know that the resources required for Venerable Jinxian to open the secret door through one person and through five people are the same.
If more than five people pass through a secret door at one time, more resources will be opened, and the quality of the secret door must be higher.
As for more than ten people passing through the secret door at one time, it is extremely rare and rare.
Only those very powerful Jinxian cultivators, or Daluo or even powerful cultivators, have such secret doors.
The Great Secret Realm is a place that many cultivators want to go to. Not only the Golden Immortal cultivators, but also the True Immortal and Immortal Lord cultivators are flocking to the Great Secret Realm.
People who don't understand may think that if you have such a low cultivation level and go to the great secret realm where there are as many golden immortals as dogs, you are looking for death.
In fact, it’s really not the case. The danger in the Great Secret Realm comes from two aspects.
The first is the danger that comes from the Great Secret Realm itself, such as star beasts in the secret realm or extreme environments.
The environment in some secret realms is very harsh, such as the great secret realm of the fire element known to Venerable Huo Tian. There are some places that even a fire element venerable like him would not dare to set foot in.
The second danger naturally comes from the mutual hunting among cultivators.
The cultivators who go to the Great Secret Realm come from all realms of the universe, and there are even some who don’t know what space they have passed through.
These cultivators at the level of Golden Immortal or above basically don't know anyone in the Great Secret Realm, and they don't have any interactions with each other in the universe.
Therefore, the Great Secret Realm is also a place where the weak and the strong prey on each other, and it is far more cruel than the world in the universe.
Stealing resources and materials is the most likely cause of mutual hunting. If many Golden Immortal cultivators are lucky enough to get some top-quality materials, most of them will immediately open the secret door and leave the Great Secret Realm.
But for cultivators with slightly lower cultivation levels such as True Immortals and Immortal Lords, the Great Secret Realm is actually not that dangerous.
Because their cultivation level is too low, most of the True Immortal and Immortal Lord cultivators are brought here by their elders, mostly to increase their knowledge and help them dig out resources.
For these cultivators, most cultivators who are above the Golden Immortal level will not take action against them, as that would be too cheap.
Therefore, when meeting cultivators above the Golden Immortal level, Immortal Lords and True Immortals will usually not make things difficult for them as long as they show their storage equipment.
Moreover, many of the venerables they mined did not like the materials. If they were lucky, they would not even have to give up their wealth. This is why some Golden Immortal venerables like to take their disciples to the Great Secret Realm.
Even people from the demon and demon clans rarely kill low-level cultivators. After all, they also have disciples who will go to the Great Secret Realm.
Of course, there are no absolutes. There are also some casual cultivators at the venerable level who are more murderous and will hunt down those low-level cultivators to obtain materials.
But beating the younger ones leads to the older ones. Usually such casual cultivators will be hunted down and hunted down in the Great Secret Realm. As time goes by, very few people will do this.
The topic has strayed far away, and now it comes back to opening the secret door to earn extra blocks.
Cultivators are a group, and those who have cultivated to the level of the Golden Immortal have countless friends, disciples, and disciples.
So when I opened the secret door, I opened it in the past, and when I brought four more people with me, I opened it again.
Therefore, some Golden Immortal Venerables used the other four places as business in exchange for some resources.
Not to mention, there are definitely more Golden Immortal Venerables without secret doors than there are Venerables with secret doors. As long as the wind is released, a lot of Venerables will line up and be willing to exchange places.
There once was a Golden Immortal cultivator who was very lucky. The secret door he found and refined from the materials reached the level of a medium secret door. When opened once, it could pass through more than ten people and twenty people at once.
This Golden Immortal Lord was born in a large sect in the galaxy of high-level cultivators. There were many Immortal Lord cultivators in the sect, and he also had many Golden Immortal friends.
So the Golden Immortal Venerable did not do anything else and simply organized a three-day tour of the Great Secret Realm.
He is only responsible for opening the secret door, and will not go there himself. On the third day after opening it, he will use the coordinates to open the secret door again in the corresponding great secret realm to let those people come back.
If you want to use his secret door, you need to come up with a lot of materials and resources.
In addition, those who enter the Great Secret Realm through his secret door will have to give him 10% of their harvest when they come back.
Even so, there are still many cultivators who are true immortals and above, queuing up to use the secret door, and business is so good that every time the secret door is opened, the number of people reaches the upper limit.
By opening the secret door once, the Golden Immortal cultivator gained ten times or even dozens of times the resources required to open the secret door.
Relying on this method, the Golden Immortal cultivator spent millions of years, and finally managed to gather enough original heavenly secrets to cultivate the Daluo Dao Fruit, and became a lucky person in all realms of the universe.
As soon as this news spread, there were actually many more people who specialized in selling secret sect quotas.
But I have never heard of anyone being promoted to Daluo Jinxian in this way.
