After spending hours of research, Ye Xing found that this formation did not have the ability to cross space.

In fact, it is only a matter of using the divine sense to place the position of the item at will, and when the item is placed on the outward teleportation array, it can be teleported out.

In the same way, it can also be teleported into a designated spatial location, and this formation can move items to a designated location, which is also activated by divine consciousness.

Now, Ye Xing has fully understood all the principles of the space bag, of course, he still needs to restore the space bag to its original folding state, if it can be successful, it will be the real mastery.

For this research, Ye Xing stayed in the room for a full fifteen days, of course, it was not without food or drink, and he couldn't completely clear the valley.

Although, he actually has food and drink, all elixir and spiritual water, and even sleeps, but he rarely sleeps, but he never opens the door.

When the spatial folding rune formation was fully understood, Ye Xing's energy was exhausted, and his body was extremely tired, so he had to rest completely.

Ye Xing packed up his things and put them in the phoenix ring, then withdrew the magic circle, pushed the door out, and saw Mu Yi staying at the door, he was overjoyed when he saw Ye Xing come out.

Mu Yi explained, it turned out that the four of them said that Ye Xing wanted to break through his cultivation and not let people disturb him, only let him guard at the door, and not let outsiders disturb here, Mu Yi stayed at the door of this room day and night, did not dare to leave, and stayed there for many days!

The four of them were not at the inn, Mu Yi said, the four of them had been out for many days, and they only let him stay here.

Ye Xing and Mu Yi came to the dining room of the inn, ordered a lot of delicacies, and the two sat down together, and they ate and drank.

Mu Yi told Ye Xing that in the past ten days, the four of them have been desperately trying to earn silver, and a few days ago, the four of them also bought a lot of tools for opening the mountain, saying that they would go to another mine to mine together, which was very weird, and they didn't come back until now.

Ye Xing and Mu Yi waited at the inn for another five days, Ye Xing's fatigue was gone, his spirit was restored, and the four of them finally returned.

Seeing the appearance of the four of them, Ye Xing could also guess what the reason was, but he didn't ask, he just let the four of them go to rest after eating and drinking, and talk about it tomorrow.

After the four of them finished dinner, Ye Xing asked the four of them to rest, and he didn't practice, but just took out the newly revised "Celestial Movement" to see, after this period of strong use and practical training, the exercises have become more and more perfect, and the newly discovered starry sky runes have given Ye Xing a new understanding, and it is necessary to redesign a magic circle that gathers starry sky energy.

The starry sky rune is actually corresponding to a certain area of the starry sky, so that the starry sky rune is automatically positioned to point to that area and attract the starry sky energy of that area.

That is to say, if there is such a starry sky rune array inside Ye Xing's brain, he can locate his own position according to the direction of the starry sky, and let the starry sky energy automatically stimulate the high-speed operation of the brain.

Thinking about all this clearly, Ye Xing was very happy, now he had to find a starry sky area that his brain was most suitable for, as long as he could solve this problem, he could locate anywhere without getting lost with such an ability, and the natural teleportation array could be more accurately positioned and teleported.

Ye Xing also thought that the superintelligence he relied on to survive in this world was obviously using the energy of the starry sky, if he could substantially master and use it, then the superintelligence might be completely recovered, which would be of great help.

Of course, Ye Xing is also faintly afraid, afraid that superintelligence is no longer controlled by himself, but reversely controls himself, which will be tragic, so don't do it, at least for now, his own autonomous consciousness is using the ability of superintelligence to calculate, reason, and derive.

Regarding the Starry Sky Rune Array, Ye Xing has a lot of ideas, but he still has to be cautious, write down his thoughts first, and slowly think about and experiment with the details, now is not the time.

At noon the next day, after having lunch together, the four of them walked into Ye Xing's room, and after Ye Xing set up an isolation array, the four of them talked about the harvest of going out for more than ten days.

Now he has purchased two pieces of ethereal crystal rough from the town, because the betrayer does not know the true value of this spar, only as a rare jade, and then forcibly bought another ethereal stone from the monk's hand by half-threatening means, costing tens of thousands of taels of silver.

After inquiry, they learned that the place where this kind of rough stone was produced, a mineral deposit hundreds of miles away, and the four of them went to excavate, and after nearly ten days of hard work, they got eight pieces of this kind of rough stone.

Now there are a total of eleven pieces of this kind of rough stone, and after the detection of everyone's divine sense, it is already certain that there are ethereal crystals inside the eleven rough stones, but I don't know the size of their space.

Ye Xing took a piece of rough stone, probed his divine sense into it, and after indulging in it for a while, he said softly, "It's really a small space inside, it's hard to say how big it is, and you have to refine the ethereal crystal to know."

The four of them were also smiling, and Pose said, "In order to find the eight rough stones in the back, I dug all the craters within a radius of fifty miles."

The Golden Seven Wolf said, "It's the first time I've done this kind of hard work, and it's so difficult to find an ore."

Zi Ying also said, "Now I also agree with why the crystal ore is so expensive, the crater within a radius of dozens of miles, the four of us are disgraced, and we have been digging for more than ten days without sleep to get a small eight pieces, if we can't succeed, we really want to die."

The trial also said, "If you can buy it in the future, don't look for it yourself, it's too painful."

Ye Xing laughed and said, "If you succeed in refining the storage space bracelet, then everything will be worth it, and I am more confident now."

Ye Xing said his perception of the past ten days, he has already understood this critical space folding formation, and he will soon be able to conduct the test, once the test is successful, then the space bag and space bracelet will definitely be refined.

The four of them became happy, and the topic turned to how to prepare other auxiliary materials, and looked at the list of materials, there are more than 20 kinds of materials, and the actual situation can only be determined if Ye Xing has studied all of them, but now it is known that he will prepare immediately.

Ye Xing said, "Next, you prepare other auxiliary materials while walking, and I, continue to study carefully to ensure a success, the Ethereal Stone is a rare skyland meteorite, and it is impossible to test it."

The four of them nodded hurriedly, and they all said, "For such a rare thing, it is already extremely lucky to get eleven pieces, it is impossible to have such an opportunity again, I believe that Brother Ye's ability will definitely succeed once."

Ye Xing really has this confidence, his predecessors can refine it, and there are so many space bags in existence, so it must not be too difficult, otherwise it is impossible to refine it in large quantities, you must know that Ye Xing's reasoning ability is rare through the ages.

Ye Xing never believed that his predecessors were really amazing, but he had never been exposed to this knowledge, the key was that no one taught him, and now that he knew the operation of the storage space, he must be able to reproduce it.

Everyone discussed, and now the materials are not complete, so they will march towards Rouran first, and the four of them will collect all kinds of materials that are lacking along the way, while Ye Xing will try to make a magic circle on the road.

After finishing, the four of them went to the town to inquire about the remaining materials, and Ye Xing began to repair the spatial folding array.

The repaired circle was actually extremely difficult, and Ye Xing's progress was slow due to the lack of materials and the consideration of extremely subtle details.

The next day, under the leadership of Mu Yi, the five of them set off again, of course, the goal was to go to Rouran, but the speed of the march was slower, because Ye Xing often had to retreat for a short time.

Ye Xing asked Po Sai to write the list of materials into multiple copies, and then when he arrived in the town, everyone inquired and purchased, and in order to raise funds, he often had to refine high-quality weapons to sell, so naturally a lot of time was wasted.

Originally, it should have been able to reach Rouran in two months, but as a result, it took more than three months to reach the border of the Rouran Empire.

Now Mu Yi also understands the personality and temperament of the five people, and helps the five people to arrange food and accommodation every day, and takes the list of items to inquire about various places, and has become the most powerful assistant of the miracle mercenary group and the real logistics housekeeper.

Ye Xing spent his energy every day researching and repairing the space folding array, spent countless thoughts and experiments, and finally achieved great results in two months, completely clarifying the methods and methods of depicting the space celestial runes, and the materials were also understood.

Ye Xing originally wanted to study it in depth, but thinking that his predecessors could arrange it and succeeded, then he really didn't need to be too obsessed with being proficient, and he could copy it first.

In fact, there is really no need to be proficient, as long as you refine it first, then take some time to correct it slowly.
