After resting for two days, Zhang Zhe recovered to full blood, took everything with him, and went out of the city alone, he was ready to find a mountain with no one and start his retreat.

Of course, he didn't go too far, there were still large oases out of the Holy City, there were many places that no one cared about, Zhang Zhe could find uninhabited peaks by looking casually.

After only one day of travel, I found a relatively satisfactory mountain, the vitality of heaven and earth is also very sufficient, and the trees are shady, obviously no one lives here, and some people are just passing by.

Zhang Zhe found a relatively flat place halfway up the mountain, took out all kinds of things, and prepared to stop here. He didn't build another small house, and although he might stay here for a long time, he wasn't prepared to live here in the future. With his practice, he is not afraid of the wind and rain in the natural world, and all the things he uses are stored in treasures, and building a house is also a waste of time.

Finding a large rock, stretching out his hand and scribbling it, he smoothed the surface like a mirror, and Zhang Zhe sat cross-legged on it, ready to start his first retreat.

Take out the smallest and thickest tuning fork, flick your fingers, there is a faint sound out, almost inaudible, this is the tuning fork that Zhang Zhe can hear the smallest vibrato, whether it is 20Hz He doesn't know, and there is no professional measuring instrument, so he can only use it. However, this is already the shortest and thickest tuning fork that can be made to hear the vibrato, and if you shrink it again, you can only hear the thump, not the trill.

Since he wanted to comprehend, Zhang Zhe naturally considered the problem of the continuation of the sound, and he specially learned a small formation, the function of the formation is to play a solid small iron ball, which will hit the tuning fork every once in a while, so that the sound can continue to be emitted.

After making all preparations, Zhang Zhe's body and mind began to merge into the innate Dao pattern and enter the state of enlightenment.

In the case of autonomous control, only the faint vibrato of the tuning fork reaches the ear, blocking out all other sounds.

As the sound entered his ears, Zhang Zhe slowly released his spiritual consciousness out of his body to explore the way the sound passed.

After the psychic consciousness covers all the paths in a straight line, the psychic consciousness begins to beat with the frequency of the sound wave, slowly merging with that frequency to form a resonance.

After the resonance of spiritual consciousness and sound waves, Zhang Zhe controlled the true element to resonate with the spiritual consciousness, and then went to the major secret realms such as the Wheel Sea and the Dao Palace to merge with the true element to complete the resonance.

This is what Zhang Zhe can do, with other people's cultivation methods, he must not change the vibration frequency of the secret realm, and Zhang Zhe uses this cultivation and studies it very thoroughly, so that the secret realm can change the frequency and true element resonance.

After the resonance of the major secret realms was completed, Zhang Zhe did not stop, but continued to control the blood qi to start beating slightly in the process of flowing, and slowly resonated with the true yuan, and then the meridians, skin, and bone marrow also vibrated together.

From the outside world, Zhang Zhe's whole person was constantly trembling, as if he was trembling, although the amplitude was very small, but it never stopped.

After doing this, Zhang Zhe integrated all his mind into the frequency of this vibration, and drove the Yuan Shen with his mind, so that the Yuan Shen also slowly began to resonate with the vibration frequency.

When everything in his body resonated with the slight sound wave, Zhang Zhe completely entered the state of enlightenment, shielding all perceptions of the outside world and himself, and comprehending the mystery of sound with all his heart.

In Zhang Zhe's feelings, he seems to have turned into a sound wave, with the help of air, transmitted into the distance, and then touched all kinds of objects, or was bounced away, or penetrated into it, with the help of the object's body, continued to spread.

Zhang Zhe can feel the shape of every object he touches, although he can't remember what those shapes of objects are, but he can know every trace of the object's external performance, and after penetrating into the object, he can also feel the subtle state of the object.

When the energy of the propagating sound gradually decreases until it disappears, Zhang Zhe's perception is also blurred little by little, and he loses that perception as the vibration stops.

Zhang Zhe's spiritual sense did not have a trace of other releases, but with the help of this vibration, he could perceive all this, which was quite surprising, Zhang Zhe was unconsciously immersed in it, unable to extricate himself.

After a while, Zhang Zhe came to his senses, the corners of his mouth rose slightly, and the pleasure from his heart filled his heart.

Zhang Zhe finally decided to find the direction of cultivation, and he really felt the joy of cultivation, and now even if no one forces him, including his own habitual practice, he will calm down and practice on his own.

The happy mood slowly calmed down, Zhang Zhe's state of mind also returned to naturalness, and he began to check the harvest of this independent enlightenment.

There is indeed a slight increase in the realm, but this is not the most important thing, the most important thing is that Zhang Zhe's basic realm has increased a little, and the increase in equal proportions is equivalent to a pyramid, which is wrapped in another layer on the outside, but there is no gap between it and the inside.

Although it only increased slightly, it made Zhang Zhe very happy.

With this change, it means that his foundation can be new and pragmatic, and he will not have a weak foundation in the future, but also have the opportunity to reach the highest level.

In the past, Zhang Zhe felt desperate when he saw his weak foundation, only when the foundation is solid, can the top be built higher, and now he can finally change his fate, he is really happy and can't help himself.

Zhang Zhe had long discovered that the size of his major secret realms was not simply decreasing upward, and his latter secret realm was a little more than three-fifths of the previous secret realm, that is, 0.618, that is, the major secret realms were all cultivated by him, and he knew every trace of each secret realm, so he could accurately understand this ratio.

What a perfectly proportioned number, and only this perfectly proportioned pyramid is the most stable pyramid that can stand tall and survive forever.

Zhang Zhe also discovered this ratio after cultivating several secret realms, which is also the reason why he can use this method to cultivate to the point where he can no longer improve, he thinks that this is not accidental.

Now it seems that this is indeed not an accident, now, the increase in the proportion of the secret realm he used to practice means that he can lay the most solid foundation, and before becoming holy, he may be able to become the most powerful mortal.

Of course, these are just Zhang Zhe's guesses, but they also give him enough confidence to continue on the path of cultivation.

What makes people desperate is not the difficulty of the road, but the lack of direction.

The first practice of trying the right direction was a success, and this success made Zhang Zhe's heart tremble, and he couldn't calm down with excitement, and he couldn't wait to start the next practice immediately.

However, Zhang Zhe is still measured, knows the truth of overreach, has read a lot of novels, and knows that people who are in a hurry will have accidents, no exceptions.

Of course, this may have been arranged by the author, but it is still enough to teach a lesson, and this kind of thing can happen through it, so now there is no difference between my legendary life and the novel.

In order to calm his mood, Zhang Zhe didn't use the power of Zhenyuan, and only relied on his body to start running wildly on the mountain, venting the excitement in his heart.

After sprinting for more than an hour, Zhang Zhe was exhausted, his mood completely calmed down, and he began to prepare for a long period of retreat.
