Gu Xiaowu only considered how to build a nest and how to move the spirit cave into the nest when he was in the middle stage of building a cave, at that time, his spirit cave was almost filled with black and white true yuan, and only the place where the floating life was located was still a little empty.

He tried to extract a trace of pure fire attribute spiritual power from a piece of fire refining yuan crystal into his body and forcibly refine it into a trace of fire attribute mana with exercises, and then arranged it in his dantian, and sure enough, this trace of mana did not flow indiscriminately, but honestly stayed in the dantian. This is also one of the reasons why this material can be used as a material for condensing cultivation, only some special materials can have their essential properties after refining, as long as this attribute mana does not flow into the spirit**, it will not be transformed, it is very wonderful. Xiao Wu was excited about one of his attempts, which he only remembered when he listened to Bingjie tell Yun Zi about the wonderful use of this fire refining yuan crystal, and then he continued to refine the fire refining yuan crystal in his hand, and finally built a messy silk net composed of countless fiery red crystal filaments in his dantian, and then he was going to try to move the spirit acupoint into the dantian.

Only then did he discover another problem of his own, this spirit acupoint is very difficult to move, this mid-stage spirit acupoint is very different from the early stage of the spirit acupoint, the energy contained in it is several times the original, and the divine consciousness required to move the spirit acupoint is also several times stronger, which is why other monks have to move the spirit acupoint in the early stage. Gu Xiaowu didn't know the reason, and he didn't see any reaction after moving for a long time, so he immediately searched for various materials in confusion, and finally found the answer in a miscellaneous book.

Xiao Wu secretly scolded his stupidity, patronizing the cultivation of the first layer of exercises, but forgot that he should first find a more specific cultivation method after his cultivation was advanced, and immediately went out to the sect trading place to find useful information, but unfortunately the information there was an introduction to the condensation, and finally Xiao Wu took the risk of using a precious material to exchange for some introduction to cave building from the condensing monk there. Gu Xiaowu was very helpless after checking this information, so he had to spend another half a year forcibly scattering the true element of the spirit ** into all parts of his body, and endured the damage of the meridians in various parts of the body before slowly moving the spirit acupoint into the dantian, and then retracted the true element in the body to recover the damage in the body.

The third problem that Gu Xiaowu encountered soon appeared, although the spirit acupoint was moved into the dantian and could still be connected with the body, but that layer of fiery red wire mesh was like a wall that hindered the close connection between the spirit acupoint and the body, and he actually felt that it was a lot more difficult to run the exercises, and even the perception of the power of heaven and earth was a little blurred.

He could only sigh and seriously reflect on his mistakes, first of all, he blindly pursued the results of cultivation but forgot about the changes in his own cultivation, and secondly, he did not plan in advance and collect all kinds of cultivation materials, and he dared to continue cultivating without knowing anything, and it was easy to go astray without knowing it.

The following time is much simpler, Gu Xiaowu gave up the cultivation exercises, but practiced the secret technique "Golden Cicada Breaking the Law" that he had already comprehended while comprehending the second layer of the "Immortal Demon Robbery Dao". Although the middle-level exercises are difficult to practice, as long as they practice more times after comprehending them thoroughly, it will be easy, so after three years, Xiao Wu finally mastered this middle-level secret art. After three years of meditation and meditation, I finally realized the second layer of the exercises, and it turned out that there was a relevant explanation of the cave building and condensing the soul in the exercises, but I didn't understand the reason for building the cave before and ignored it, and then started my own acupoint building practice according to the content of the second layer of the exercise.

After the trial of the second layer of exercises and continued enlightenment, he finally completely understood all the meaning of the foundation stone of the treadmill, and this second level should be able to cultivate to the stage of becoming a pill. According to the above, after entering the Tao, you can feel the power of heaven and earth and refine it for your own use, but if you want to get more and more powerful power from heaven and earth, you must first have a container that can carry the power of heaven and earth. This second layer is to explain how to prepare to carry strength with the body, which is laying the cornerstone for the acquisition of the road, and it is also a key step in whether you can go far on the road.

After understanding thoroughly, I also found a way to build a nest from the inside, although the words in it are called the spirit cave shield, but from the specific practice, it is the same purpose as building a nest. He took back all the mana threads that were still woven haphazardly in the dantian into the spirit cave and transformed them into pure mana, and now that the spirit cave was emptied, he could start trying new construction methods.

Next, he took out all the precious materials used for building caves and condensing spirits, and divided them into categories according to the attribute categories, and after silently calculating in his heart, he took a piece of material and tried the exercises.......

This immortal demon robbery Dao exercise is wonderful, can produce three forms of mana in operation, one is to absorb and refine the spiritual qi into ordinary pure mana stored in the body, this method is the simplest, but the amount of mana that needs to be condensed is the largest, because they need to be distributed all over the body, is the basis for how much ability the body can exert; But it is used to extract special powers in various materials, and it is necessary to carry these attribute powers around his body, and finally return to the dantian together to build a protective shield for the spirit cave. Although it will bring great pain to all parts of his body, it is also to refine his body, so that it can be more adapted to the various forces of heaven and earth, and he can still hold on to it if he endures it. Although this immortal demon robbery path becomes more and more complicated the more he cultivates, the truth in it is still acceptable to Xiao Wu, if he wants to compete with heaven and earth for life, he will not easily achieve his goal, which is also the tempering he needs to endure.

There are no specific restrictions and explanations on what resources to use and what kind of nests to build, but it only mentions that the richer the power that the body absorbs and refines, the more obvious the effect of the final exercises. Although there are only five kinds of resources in his hand, all of them are single-attribute materials, but the number is definitely rich, so there is no need for him to go around buying the materials needed for Ning Ling, as long as he uses up these single-attribute materials in his hand, there will be no problem with Ning Ling. But it didn't take long for him to encounter a fourth problem, and he has been bothering him ever since.

In the end, I have to admit that this Immortal Demon Tribulation Dao is really not something that ordinary people can cultivate, no matter the pain that will be brought to him in cultivation, or the amount of resources required for this cultivation is not something he can bear, the seemingly amazing amount of materials in his hand, after the polishing of his own exercises, there are not many spiritual threads that are really used to condense into caves. This made Gu Xiaowu sigh that he chose the most resource-consuming exercise, and the five pieces of Fire Yuan Refining Crystal in his hand were only refined by his own special exercises, and the other materials were similar, and finally when he consumed all the materials that could be refined in his hand, there were only dozens of filaments. But each of these filaments is also wound with two thin chains, one is composed of black and white mana true elements, and the other is a crystal line condensed by divine thoughts, and the three are tightly woven into a slightly thicker rope like a braided rope, but unfortunately there are only so many dozens of ropes of different lengths, and there is no tight clothing for the spirit cave to wear. Originally, Xiao Wu was full of confidence, but he had to worry about whether the resources in his hand were enough, did he still have to go out to collect resources? Can he collect resources in the wilderness? Gu Xiao Wu couldn't help but have a headache.
