Not wanting to fly over that crack, Feng Ruo searched down this huge and terrifying crack, and now he had finally found two reference positions in this black abyss, and he didn't dare to guarantee that with these two reference positions as the center, he could guarantee that he would not lose his way within a radius of ten thousand miles. Of course, this premise is that you won't meet those third- or fourth-level demon kings. After wandering around like this for two or three days, Feng Ruo finally found a suitable retreat place for himself, this is one of the many mountains, there is nothing special, and he didn't pay much attention to it originally, but when he passed by here by chance, the purple water spirit in his body once again sensed a low-grade dragon crystal. Feng Ruo hadn't figured out the understanding of this thing yet, but he knew that this thing was very valuable, and the purple water spirit could sense this dragon crystal, which also made him feel very curious, so he took a little effort to collect this low-grade dragon crystal, and then he found that there was actually another space under this mountain. Feng Ruo, who was worried that he couldn't find a place to retreat, was suddenly overjoyed, so he cautiously entered the place of this mountain, which was naturally formed, and there was no trace of the demon king's infestation, and this place was nearly a hundred zhang deep from the ground, so after some investigation, he decided to build his retreat cave here. Of course, if this space is not very large, if the belly seal of the mountain will not move, he began to dig down in the most hidden corner, and while digging, he used purple fire at the same time to melt the gravel behind him and then re-block, so that even if the demon king accidentally broke into the belly of this mountain, he could not find the entrance to his cave. In this way, it was dug down for a full 500 zhang. Feng Ruo just gave up. And this five-hundred-zhang passage was also melted by purple fire at the same time, which means that his cave is six or seven hundred zhang away from the ground, even if there is a fourth-level demon king going crazy on it, he can't help it! And at this time, it is the time to build a real retreat cave, Feng Ruo first used the Allure Sword to carve out a space that is at least about a thousand zhang in a radius, such a large space is of course not something he wants to enjoy, but wants to emulate the nest of the fourth-level demon king. In the lair of the fourth-level demon king. The surrounding rock walls were so hard that even Feng Ruo's Alluring Sword was helpless due to the countless magma flames that scorched it, and there was no doubt that it would be an excellent means of defense. Feng Ruo is now building a second line of defense for his retreat cave, it's not that he's too careful, it's really because this black abyss is too perverted, he doesn't want to go through all the hard work himself, and he can finally hit the spirit infant stage, but when he is about to kick his head, he is bad! He now knew the horror of this purple fire, ordinary rocks could melt into magma in the blink of an eye, so he burned all the rocks in the entire space with purple fire, waiting to remove the many impurities in it. What was left behind was a rock that was as hard as fine iron! With these rocks, he built a stone house with a radius of only twenty zhang, and this stone house had no doors, windows, and entrances and exits, so he controlled the purple fire inside and poured it layer by layer until the entire stone house was completely formed. The thickness of this stone house is more than ten zhang, according to Feng Ruo's estimate. Even if it's a third-level demon king, don't think about crashing into it in a short period of time! Of course, this is just one of them, when building this special stone house, Feng Ruo didn't forget to arrange various formations in it, and in the end, it consumed nearly six hundred or so top-grade Five Element Stones, with these formations. No matter how much he tossed inside, there must not be any bō movement to pass out. After building this almost perverted stone house, Feng Ruo breathed a sigh of relief, if it were other cultivators, he would definitely not do this, because it was safe to do so, but it couldn't relieve the Heaven and Earth Yuan Qi, and ordinary cultivation was just that, but it was definitely a joke to impact the Spirit Infant Stage. Because the cultivator's impact on the spirit infant stage not only requires the cultivator to accumulate a large amount of mana, but also needs to deal with a huge amount of heaven and earth vitality, therefore, the best place to impact the spirit infant stage is those places where the spiritual veins are abundant, and there are not too many blocking formations, because that will affect the flow of heaven and earth vitality. But Feng Ruo is now doing the opposite, he not only drilled into the place of six or seven hundred zhang underground, but also built a perverted stone house that can't penetrate the slightest bit of aura, not to mention the aura of heaven and earth, even ordinary air, don't even think about penetrating the slightest, in this case, it is almost a taboo for cultivators...,

You must know that even if a cultivator has mana and can maintain normal life operation without breathing for a long time, this kind of thing is still okay occasionally in normal times, but it is absolutely not possible in normal cultivation, let alone this critical moment of impacting the spirit infancy, because the slightest difference will lead to immeasurable consequences! Feng Ruo understands this truth very well, but he still chooses this way, the reason is not that he wants to die, nor is it because of the environment! In fact, a long time ago, Feng Ruo had already been thinking about his preparations when he was impacting the Spirit Infant Stage, at that time, his Purple Fire had not yet advanced, nor had he fused the Purple Water Spirit, let alone indirectly subdued the Innate Water Demon! At that time, Feng Ruo still wanted to impact the Spirit Infant Stage in the same way as an ordinary cultivator, because at that time, even if he had two Innate Spirit Veins and controlled the Innate Wood Evil and the Innate Water Demon, the gap between him and ordinary cultivators was not very far away, and it was not too exaggerated! However, when Feng Ruo fused with the Purple Water Spirit and fused the Xuanhuo clone with the Purple Fire to form his right arm, the gap between him and ordinary cultivators could already be described as worlds apart. And it is precisely because of this that the advanced methods that are suitable for ordinary cultivators are not suitable for him at all! Ordinary cultivators need to rely on the power of heaven and earth to attack the spirit infancy, after all, cultivators are going against the heavens, and they must try to make their own conditions as close as possible to the power of heaven and earth, and imitate them, so that they can reverse the power of heaven and earth for their own use. But does Feng Ruo still need to rely on the power of heaven and earth now? Answer: Yes, not much! This situation is not intentional by Feng Ruo, and he can't do it on purpose, in fact, his current fate, everything he needs now, has been transferred from the power of heaven and earth to his body, in other words, he can already be self-sufficient to a large extent. Of course, whether it is the Purple Water Spirit or the Purple Fire, or the Innate Wood Sha, the Innate Golden Sha, or the Congenital Water Sha, they all belong to the entire heaven and earth in principle, but they have become their own sī items, and when other ordinary cultivators are still struggling to absorb the aura that is floating in the heavens and the earth, he no longer needs it! But this is not necessarily a good thing! The vastness of heaven and earth, the secret of the Heavenly Dao, is not something that Feng Ruo can imagine and control at will, every time he masters a little more power, he has to bear a little more pressure, he now controls the innate wood sha, the congenital golden sha, the congenital water sha, and the purple fire in one go, which is absolutely unimaginable in other cultivators. Usually, it's just that, but if it is to impact the spirit infant stage, it is equivalent to this kind of extremely powerful power in his body to redivide the territory, this is inevitable, Feng Ruo will not be idiotic to think that everything will be fine, there are some dangers, but it has not reached the critical point! Therefore, it is precisely considering this situation, coupled with the environment he is in now, Feng Ruosuo has a heart, and wants to impact the spirit infant stage in a way that is completely different from the advanced of ordinary cultivators. That is, completely isolated from the power between heaven and earth, he doesn't need the Heaven and Earth Yuan Qi Condensation, not even at all, because his body is already chaotic enough, and his body can't bear a little more power! But this way of impacting the Spirit Infant Stage has not been tried since ancient times, since the ancient god created the cultivation system for cultivating the Spirit Infant! Feng Ruo didn't know what the result would be? He had to go all out! In his opinion, the so-called impact on the spirit infant stage is not a difficult thing, as long as he integrates the chaotic power in his body and determines a foundation, then he is already a spirit infant stage cultivator, this is beyond doubt, because the various forces in his body are different from each other, and they are tearing each other down and suppressing each other at all times! And if Feng could integrate the chaotic power he had now into fifty percent, or seventy percent, then the power he burst out would be enough for a spirit infant early stage master to run away, even in the middle stage of the spirit infant! Of course, things are not so simple at all, these forces entrenched in the sealed body are not one or two kittens and dogs, whether it is the congenital wood or the congenital gold, the congenital water evil, or even the purple fire, any one of them can be taken out breathtakingly, dare not despise, this is the most extreme power existence in the immortal cultivation world! Therefore, Feng Ruo's greatest wish is to be able to exert at least fifty percent of these powers, so that the fusion between them can go further, as for the perfect fusion, he didn't think about it at all, because it was definitely a very distant, very distant thing. However, although it was completely different from the advancement method of ordinary cultivators, Feng Ruo did not think that he would subvert the cultivation path of the Spirit Infant, he would still achieve the Spirit Infant, but what kind of power was this Spirit Infant made of? What proportion did they occupy? Who would restrain whom? Who would assist whom? This was the most troublesome, the most dangerous, and the most thorny thing!。
