Early the next morning, Gu Xiaowu took advantage of the fact that there were not many people who came out in the early morning to carry out activities, and went to the sect trading attic to collect some information and simple maps about the Blood Sand Mountain Range and the surrounding situation, which were much more comprehensive than those given by Deacon Zhao, and the price was only four hundred spirit stones, which made Xiao Wudi speechless.

He never left his attic for the rest of the year, and now he already knew that he had slept for ten years, and in the end he only got one 'sleeping' exercise, which could only mean that he accepted his incompetence. Fortunately, the exercise was picked up by the two guys of the spirit ** mung bean and blue bean, they were connected to Gu Xiaowu's mind, Xiao Wu could understand it, of course they also understood it, and immediately cultivated on their own. And what made Gu Xiaowu most happy was that the ignorant red bean also seemed to be interested in that exercise, and also fell asleep paradoxically. This time, the three guys have been asleep for a lot longer, it should have been more than four years, I hope they can surprise themselves when they wake up, so that it is worthy of the ten years he wasted.

Gu Xiaowu cultivated with peace of mind, but the cultivation speed was not fast, although it was no problem to comprehend and refine the spiritual energy on the spirit stone on those two wonderful peaks, but as soon as he arrived at the place where the spiritual energy was strong, he found that the speed at which he operated his mana had actually slowed down, and the thick external aura actually hindered the running speed of his exercises. Although I can still feel the various powers in the aura, and those powers have become larger, I am hindered when I extract those powers from it. It is very easy to extract a trace of the power in the aura, but when the power of the aura of heaven and earth exceeds that of oneself, it is extremely difficult for oneself to extract a trace of refining from it, this should be the kind of situation written in the Taoist book, the monk has been seizing the power of heaven and earth, and heaven and earth have been hindering the monk's seizure.

If you want to cultivate the second layer of the Immortal Demon Tribulation Dao, you must be able to easily run the first layer of exercises, so Gu Xiaowu patiently cultivated, slowly increasing the speed of refining the power of heaven and earth, and when he reached a certain time, he could cultivate the foundation stone of the treading path. It's just that he doesn't know how far he can advance his cultivation before he can be considered the end of the first-level exercises, the biggest problem with this Immortal Demon Tribulation Dao is that it is not created according to the current level-level cultivation system at all, which makes Gu Xiaowu very troubled himself and doesn't know what preparations are needed to advance and what resources to use?

Gu Xiaowu's retreat is not no one cares about, the four people who traveled with him have been looking forward to him for a long time, but unfortunately the attic where Gu Xiaowu lives has been closed, making their minds unable to succeed. In the end, the four of them joined a team composed of fellow Daoists in the cave building period and began to search and hunt the black lion, but within a month, there were two fewer people among the original four, which made the remaining two people extra careful, and they were not so concerned about Gu Xiaowu, because they also saw that this little Tuoji planned to retreat and cultivate all the time, and would not come out to move at all.

Ten years and ten years, Gu Xiaowu never went out except for paying the rent of the attic once a year, and he had no intention of leaving the fortress, and no one else paid attention to such a Tuoji monk who rarely showed up.

The black lions near the Black Lion Mountain did not decrease rapidly because of the slaughter of the monks, even those disciples in the condensation stage could only hunt and kill three or four in a year, after all, the strength of these black lions was amazing, and their spiritual intelligence was not low, and it was always easy to escape if they couldn't beat them. However, the number of monks who die in the mouth of the black lion every year has not decreased, but because the area of the search has increased in recent years, many disciples have not come back as soon as they went out, and there have even been three cases of the inexplicable disappearance of the ten-person team of Ning Ling, and finally the Nine Sound Valley had to transfer a Chengdan stage elder to sit in charge.

Gu Xiaowu didn't know if the mission of exterminating the Black Lion Castle was smooth or not, but he knew that his cultivation of advanced spirit condensation was not going well. In the third year after the retreat, he easily advanced to the cave building period, and finally realized the difference between the cave building period and the topography. The divine consciousness has been strengthened by two times, and at once you can clearly feel everything within the range of 100 zhang, even the movement within 200 zhang can be perceived. Not to mention the mana, his body seems to have doubled in size all of a sudden, and the mana that he had accumulated and condensed before was only thirty percent of the original, and after breaking through, a large amount of true yuan of the spirit ** was scattered all over the body, and finally the body was in a state of false fullness, ensuring that the meridian body would not shrink. In this way, the spirit ** is vacant, and the internal space has also expanded a lot, and the floating life only occupies a little space inside, and the layer of cyan silk satin that originally appeared outside the spirit cave after absorbing the green silk wood actually melted into the outer wall of the spirit cave, making the spirit cave appear more mysterious. But Gu Xiaowu finally discovered the secret of this spirit cave, its inner and outer walls turned out to be a kind of crystal barrier condensed by divine thoughts, and around the spirit cave, there are countless mana threads rotating around it, and at the same time, the spirit cave can also be urged by divine thoughts to move autonomously.

The purpose of both the acupuncture period and the foundation building period is to continuously deepen the communication between the spiritual acupoint and the body, and if you want to succeed in condensing the spiritual acupoint, you need to first build a more suitable place outside the spiritual acupoint and expand the spiritual acupoint. Ning Ling and Cheng Dan are both imitating the spirit acupoint and maximizing the role of the spirit acupoint, so the building of the acupoint before the condensation period is to find a more suitable and wider nest for the spirit acupoint. These principles are already well-known to monks, as long as the monks who build the cave successfully, they will begin to build a nest for the spiritual cave in their dantian, which is not only the place with the largest space in the body, but also the place that is most in line with the balance with the body, and the difference between the monks also starts from building their own unique spiritual nest, because the nest built will sooner or later change into their own inner pill.

How to build a nest has become the first problem that Gu Xiaowu faced, there was no writing in those materials about how to do it, and I had never heard anyone say how to do it before, but there was a space bracer in his hand that Yun Lan helped him classify all kinds of precious materials that could help him condense the spirit, but he didn't know how to use it. Gu Xiaowu didn't have a way to build a nest in his hands, and he didn't know the tricks inside, so he didn't start building a cave at that time, but continued to practice the first layer of the Immortal Demon Tribulation Dao, and set aside a part of the time every day to comprehend the second layer, until after another thirty years, he finally broke through to the middle stage of the cave building, and the first layer of the exercise was also completed, and he seriously thought about how to build a cave.

It stands to reason that every successful disciple who builds a cave will first collect all kinds of information on condensing the spirit and building a nest, and then choose the method of condensing the spirit according to the resources in hand. Due to the different exercises of cave building, different physical qualifications, different personal attributes, different types of resources in hand, etc., it is difficult to find two people who build the same nest among the thousands of monks who condense the spirit, but there are indeed many similar points, and many famous cave building techniques have also been promoted, and many disciples of the same sect and master are also roughly similar. Some monks build their own special nests because of their own differences, and some pursue unique avenues and build alternative nests, in short, this is the only chance that monks can do as they want since they have cultivated, because there are no special requirements for building nests, as for whether the final spirit condensation can succeed, it only depends on whether they build it densely, whether they can attract the nest to be closely connected with the spirit cave, even if the spirit condensation is not successful, it is just that their own spirit cave does not have enough contact with the nest built, If you want to make up for it, you just need to keep strengthening your own nest.
