So Hetu Luoshu said slowly, "Another method is to wake me up through this sonic attack of Pu Lao, the reason why this method is the most difficult is because almost no one knows the location of Pu Lao's lair. Not only that, even if you are lucky enough to find a pujiao, if the other party's strength is too strong, if you don't pay attention, you will be shattered on the spot by the sound waves emitted by it. Therefore, this second method is the most difficult, and if you are not careful, you will lose your life. I really didn't expect that your luck would be so strong, young master, and it happened that it was the most suitable place to awaken my sleeping consciousness at the moment. Moreover, the strength of the young master Qianyuan Realm can just strengthen your physique." When he said this, Ling Feng said, "Although that's what I said, how can I escape from here later, with my current strength, I don't even have the slightest resistance in front of Pu Xuan." Not to mention strengthening the physique." Hearing Ling Feng's somewhat helpless words, Hetu Luoshu spoke again and said, "Don't worry, young master, I have a way for you to cultivate." As for your safety during your cultivation, just leave it to me." Since Uncle He said so, of course Ling Feng chose to believe him, after all, Uncle He had helped him overcome many difficulties before. So he said, "Okay, Uncle He, you can start it later." Let me prepare first".

Uncle He said, "Young Master, you don't have to make any preparations, you just need to regain control of your body in the outside world, and let me do the rest." However, you need to be aware that the sonic attack I will cause will definitely cause a drastic change in the sea of spirits, and your mind will be slightly deranged, which means that you may see some hallucinations. If you really encounter that kind of situation, young master, you must stay awake, otherwise you will be hit hard if you are not careful." Then Ling Feng squinted at Uncle He and said, "Uncle He, didn't you say that my safety is fine." Hetu Luoshu felt Ling Feng's eyes, and said, "Yes, young master, your safety can be guaranteed, what I said is that life will not be threatened, as for whether you are injured or not, it is not within my control." Besides, don't you always say that wealth is in danger?" Ling Feng could only sigh helplessly and said, "Okay, wealth and danger are in danger."

As soon as Ling Feng finished saying this, he saw that Hetu Luoshu's gesture changed, and he directly formed a handprint and hit Ling Feng's back. Of course, Ling Feng also felt the change in his back, so he asked, "I don't know what just happened, Uncle He." "Actually, it's nothing, it's just a rune that can induce Pu Lao to carry out a sonic attack, and it can also temporarily keep your life safe." When your consciousness merges into your physical body again, that rune will take effect and trigger Pu Lao's attack, and then I will take the next step to help you exercise your physical physique again, young master." Although Uncle He said this, Ling Feng still felt that he had no bottom in his heart, after all, the other party could easily defeat Pu Jiao of the Qianyuan Realm, and his current strength was completely heaven and earth compared to the other party. Although he thought like this, Ling Feng still believed in Hetu Luoshu, so his consciousness merged into his body again without hesitation. It's just that when Ling Feng regained his body, he found that he was buried in the mound. So his head burst through the mound of dirt and began to breathe in the fresh air from the outside world.

After relieving his tired body for a while, Ling Feng's entire body began to break through from the mound. As soon as Ling Feng came out, the runes on his back began to work. At this time, Pu Lao in the outside world obviously felt a mysterious attraction coming from the earth cave. In order to find out what it was, Pu Lao released a sonic attack, but because it was a temptation, the power was not very great. Even so, Ling Feng was also hit a lot. Under the collision of this sound wave, the body once again made close contact with the earth wall behind him. After stabilizing his body, Ling Feng said to himself, "Uncle He can't be lying to me, how can this level of sound waves help me refine my body, is it just to constantly attack my body, and then take the opportunity to break through the limit at this moment?" Hearing Ling Feng's question, Hetu Luoshu spoke, "Young Master, don't get me wrong, Pu Gao's attack just now was just to test the reality of that rune. Presumably, the next wave of attacks, it will go all out."

Ling Feng, who heard Uncle He's words, wanted to ask questions, but the outside world really changed greatly at this moment. At this time, because of the temptation to feel the rune behind Ling Feng, Pu Liao went violently, and without saying a word, he used his strongest sonic attack to attack the earth cave where Ling Feng was. Under this wave of attacks, the earth cave where Ling Feng was located was directly moved to the ground, and this area was also full of dust, so there was no situation in which Ling Feng could not be seen at all. When the dust cleared, a humanoid mound of earth appeared in the middle of the flat. It seemed that Ling Feng had blocked this blow with his very human physical strength. Although he blocked this blow, Ling Feng did not react at this moment. The reason why this happened was entirely because this sonic attack had already entered Ling Feng's spiritual sea, and at this moment, Ling Feng's soul was suffering from the pain caused by the sonic attack. From time to time, Ling Feng would feel as if his spirit was out of order.

There is only one circumstance that Ling Feng will feel better, and of course the feeling here is only relative to the most painful time. It was only when he switched between sound waves that Ling Feng felt a little better. It can be said that this kind of moment is what Ling Feng desires the most now. Although it was said that every time the sound wave switched, the interval was very short, and the power did not decrease much, but in Ling Feng's opinion, it was the happiest. If this had been placed on an ordinary cultivator, it would have been wiped out long ago. Although the sonic attack was very powerful, Ling Feng's most fundamental thing did not suffer any damage. Moreover, under the effect of this sound wave, Ling Feng's soul strength had a vague upward trend. Not only that, but at this moment, Ling Feng's spiritual sea was also surging as before, but unlike before, this time the spiritual sea was churning much more violently than before. Hetu Luoshu, who felt the changes in the spiritual sea, also quickly controlled his soul body to the top of the main body, and then sat cross-legged on it, closed his eyes and used the main body to continuously suppress the restless spiritual sea.

It seems that this move of Hetu Luoshu was very effective in suppressing the spiritual sea that was rioting, and after the spiritual sea stabilized a little, Uncle He left from the ontology, but when he left, Uncle He still moved Hetu Luoshu to the center of the spiritual sea to avoid the spiritual sea from rioting again. After doing all this, Uncle He began to pose in a strange posture again, constantly using the spiritual power in Ling Feng's body to resist the incoming sonic attacks, originally thought it was just a simple resistance, but it turned out that the defensive shield erected by Uncle He at this time, every time a trace of sound waves passed through it, the sound waves seemed to be purified. This purified sound wave power directly wrapped around Ling Feng's body after it came out, and finally formed a thin film around Ling Feng's body. As more and more sound wave power is transformed, the role of this film is also revealed. It turned out that the function of this film was actually used to envelop those mysterious powers that overflowed.

After those mysterious powers reached a state of overflow, Ling Feng's skin began to change gradually. The skin that was originally dull, under the action of mysterious power, began to slowly appear on the surface of the starlight. The overall look revealed a slight sense of mystery in the depths, and looking at it for too long would give the cultivator a sense of depth, as if the starlight on Ling Feng's skin would constantly move. Of course, this soon ended with the disappearance of those mysterious powers. Of course, at this moment, the first wave of sonic attacks in Pu Lao has also ended. Of course, Ling Feng's cultivation would definitely not end because of this, after all, in Hetu Luoshu's opinion, all this was just the beginning. Therefore, Uncle He's gesture changed, and the mysterious rune on Ling Feng's back shone again, and the same Pu Lao once again felt the mysterious summoning power coming from Ling Feng's back. This time it was no longer calm, because it felt a sense of fear that came from its bones, as if it were their natural enemy, and it was something that could suppress them.

Since Pu Lao had this feeling, it must be ready to destroy the other party, especially since the blow just now did not cause any damage to Ling Feng, which also increased Ling Feng's threat in its heart. So Pu Lao launched a second sonic attack, and it was obvious that this attack was much stronger than the first, which could be clearly seen from the hole under Ling Feng's feet. Because this time, compared to the ground, the place where Ling Feng was located was directly under the action of sound waves, sinking twice as deep as the hole that Ling Feng had dug before. The same Ling Feng's body also fell to the bottom of the giant pit. Not only that, but the walls of the crater were lined with threads, which was clearly due to the trajectory of the sound waves. Of course, these sound waves also all invaded Ling Feng's spiritual sea. As soon as these sound waves entered Ling Feng's spiritual sea, they were firmly controlled by Uncle He, and the rhythm of those sound waves gradually slowed down. Then, under Uncle He's control again, one by one, it was transformed into the mysterious power that helped Ling Feng forge his body. As soon as these powers appeared, they directly began to continuously strengthen Ling Feng's body, and the flickering starlight on Ling Feng's body was also much more gorgeous than before. Of course, all this is just a psychedelic appearance.

At this moment, what Ling Feng was suffering was the pain of separation of flesh and bones. This is all caused by the effect of mysterious power, in fact, this mysterious power also has a name that is familiar to cultivators in the crape myrtle realm, that is, the power of the source sound. If the cultivators of the Ziwei Realm knew that there was a source sound power generated here, I am afraid that they would all come here with their heads squeezed. The reason for this is entirely because the power of this source sound is the most primitive and purest power of sound waves. If a cultivator can get a trace of it, he can use it to increase the strength of his physical body, of course, this is only one of the effects, and ordinary cultivators will not use it to refine their bodies when they get the power of the source sound. Because in their opinion, using the power of the source sound to forge the body was completely a waste, not to mention anything else, just the pain of separation of flesh and bone caused by the forging of the body was not something that ordinary cultivators could bear. Moreover, the power of the source sound is very insignificant to the general physique, so only someone like Ling Feng who has a rare physique can feel the great effect that the power of the source sound brings to him.

The reason why most cultivators are bent on obtaining the power of the source sound is entirely because they are not only able to peek out a trace of the origin of the sound power from it, but also use the power of the source sound to open the huge treasures left behind by those dungeons. Of course, peeking into the origin of the power of sound is actually of no use to ordinary cultivators, and what they value most is the treasure left behind by Pu Lao. You must know that there was once an unknown cultivator, because of the coincidence of the power of the source sound to get the treasure left by Pu Lao, and finally with those treasures is all the way up, it didn't take long to become one of the peerless powerhouses at that time. You must know that it is a peerless powerhouse in the Ziwei Realm, and it is definitely not comparable to the Ethereal Continent that Ling Feng is in now. One can imagine how attractive this treasure is for cultivators. At that time, because of this incident, the power of the source sound in the crape myrtle realm was speculated to a sky-high price. At that time, the power of the source sound of a jade bottle had already reached the same price as a high-level weapon of the spirit level, and it was also the kind of spirit weapon that came from the hands of a famous master and was close to an artifact.

You can imagine the preciousness of the power of the source. Fortunately, there are no magic weapons in the current Ziwei Realm that can effectively sense the power of the source sound, otherwise Ling Feng's situation would be really dangerous. Of course, Uncle He was also aware of this, so he dared to extract the power of the source sound in this place, and then help Ling Feng quench his body. Otherwise, Uncle He would really be looking for death. In fact, the reason why this source sound power is so precious. There was another reason, that is, there was no way for cultivators in the entire cultivation world to extract the power of the source sound. Except, of course, the book of Hetuluo. The reason why I say this is entirely because the Hetuluo Book is something that existed in ancient times, if it is more accurate, the Hetuluo Book should have appeared at the beginning of Chaos, so it is said that the Hetuluo Book records all the exercises and martial arts since the birth of heaven and earth. It's just that now because of the incomplete book of Hetuluo, Uncle He's memory is far from that much. However, at present, it seems that this method of extracting the power of the source sound is precisely preserved in this part of the Hetuluo book itself. It can be said that any thing that Uncle He showed today, as long as it is taken out, it may not be able to cause too many fluctuations on the Ethereal Continent, but if it is in the Crape Myrtle Realm, it will cause turbulent waves. Of course, all of this is not clear to Ling Feng at this time. He didn't even have time to notice the changes that were taking place in him, as all his attention was focused on the pain that the sound waves were causing to his soul.

At this time, the severe pain brought by the soul made Ling Feng feel as if he was about to die, but this kind of thing could not bring him real death, he could only continue to bear that kind of pain, and the most uncomfortable thing was that Ling Feng's consciousness was very clear at this moment. Tasting the stinging sensation brought by the soul under the sober consciousness was exactly the situation that Ling Feng was in at this time. Under this kind of torture, the thought of dying once popped up in Ling Feng's mind. But he was soon interrupted by himself, because he still had his mother to rescue, and Yi'er to meet, which did not allow him to commit suicide at will. Therefore, Ling Feng had no choice but to keep hovering on the edge of pain like this. It didn't take long for the side effects of this round of sonic transformation to Ling Feng's soul to disappear. Although the pain of the soul is gone, the pain of the body immediately replaces the pain of the soul. And this is also the time when the power of the source sound is at its strongest.

In other words, Ling Feng's quenching body at this moment is the most intense time. The same was when Ling Feng felt the separation of flesh and bone the most intensely. This time, it can be said that Ling Feng completely felt the pain of what is called the separation of flesh and blood. It is clear that this pain is not the same type at all from the previous one. The previous pain came from the soul, but this time the pain came from the body, and finally conducted in the nerves deep in the brain. Therefore, this time Ling Feng was holding his head with his hands, and from the outside, he looked like he was in pain. After all, Ling Feng's pain nerves were really stimulated at this time, and this was still on Ling Feng's body, if it was placed on other cultivators, it was estimated that he would not be able to bear it and faint to death. Although Ling Feng could withstand it without fainting, he had to endure inhuman torture. This may be a test of Ling Feng's mind.

In fact, the pain caused by all this Uncle He couldn't be clearer, but Uncle He didn't tell Ling Feng what he had to go through, which can be regarded as a test for Ling Feng by Uncle He. Because in Hetu Luoshu's opinion, if Ling Feng can't even withstand this test, then he may really be a little unsuitable to be the master of Hetu Luoshu. To put it bluntly, this time it is a project used to assess Ling Feng's mind after Hetu Luoshu wakes up, if Ling Feng passes, not only can his physique be strengthened, I am afraid that Uncle He will definitely do his best to cultivate him in the future. If Ling Feng can't meet the standard in Uncle He's heart, I'm afraid that if Hetu Luoshu fuses the rest of the remnants in the future, he will leave Ling Feng, and whether he will find a suitable master is Hetu Luoshu's own business. However, with the character of Hetu Luoshu, it is estimated that he will not find a second master.

The reason why Uncle He thought so was entirely because after Hetu Luoshu fell asleep this time, he regained some of his memories. And the secrets involved in this part of the memory are too big. Hetu Luoshu can be regarded as understanding the reason for its existence in this world. As for the reason why Ling Feng came to this world, Hetu Luoshu also had some preliminary understanding.
