It is not an easy thing to tear the space, although Xin Yu has Chen Linqiang's guidance and has the experience of personally shuttling through the space, but it is not an easy thing to successfully split the sky and teleport in one fell swoop.

Of course, even in terms of the total amount of spiritual power, Xin Yu had the basic ability to tear through space as early as when he had just reached the subtle realm. It's just that at that time, his grasp of his own spiritual power had not yet reached the point of being meticulous, not to mention that he could not control the output of his spiritual power by himself.

Although the perception ability is meticulous or not, it is equivalent to the resolution of the camera, if the resolution of the camera is high, the effect of natural monitoring and ingestion is much better, but as long as the resolution is not too low, it will be enough, but it can also be used.

In the same way, if the mental ability to perceive is excellent, it is true that in the process of perceiving whether the space is weak or not, it will have the ability to perceive more and more detailed spatial conditions than a person with weak perception ability.

However, although the density of the heterogeneous distribution of space is also very dense, there may be subtle weak gaps at the molecular and even atomic and electronic levels. However, as far as an astrologist is concerned, mental perception does not need to be so accurate. Because the uneven distribution of space, or the weakness of a certain space, is not necessarily subtle to that extent.

Of course, if you can perceive a more subtle degree, it will naturally be easier to find the weak points of the space, and it will naturally be easier to tear the space, as long as you can have enough control accuracy and strength.

This is also why some astromagicians can shuttle through space anytime and anywhere, while some astromagicians must choose a specific location before shuttling, because they can't clearly perceive the subtle weak points of space, so they naturally don't know where to start tearing the space.

However, don't dare to be able to perceive how delicate it is, for the star magician, perceiving the weak point of the space is a prerequisite for shuttling through the space, but just like the problem of having and not and the problem of having and refining, being able to perceive the obvious spatial weakness is enough to advance to the Heaven Split.

For Xin Yu, this is not a particularly difficult thing, at least now his spiritual power has become stronger...... And because he almost started to accumulate and purify his spiritual power again, Xin Yu's control of his spiritual power now is different from before.

As far as the perception of the microcosm is concerned, although Xin Yu is not as powerful as those strong or astromagicians who specialize in the laws of space, and can perceive countless spatial weaknesses in the space, he is now at least much stronger than those astromagicians who have just stepped into the realm of Heaven Splitting, after all, if he can perceive the strength of space or not, he will definitely have a higher and better start and starting point than other Sky Splitting Star Magicians.

Therefore, even if Xin Yu has handed over the perfect "graduation paper" in the subtle realm, and has raised the level of his spiritual power perception to sub-nanometers, that is, at the level of molecules and atoms, if he can't distinguish the strength of space, it is impossible to perceive where the weak point of space is.

In this regard, Chen Linqiang's existence has given Xin Yu a lot of help, at least although Xin Yu himself has observed and realized this aspect when he experienced space travel before, but it is not very easy to make a detailed judgment.

After all, space itself is a conceptual thing between nothingness and substance, and it is impossible to distinguish between stable and unstable space if the understanding of space is not sufficient.

It may be a bit vague to say this, so let's use a figurative analogy. In this metaphor, space can be seen as a huge body of water with uneven material density, and humans are fish living in this body of water, generally speaking, if the situation is stable, the density of the water body is the same in most places, but because there may be some air dissolved in the water body or local temperature differences, which leads to the subdivision into each small point, the density of the water body is different. If the density is high, then the stability of the water body in this place will definitely be stronger...... This is also similar to the distribution of "density" in space, where the density is small, it will naturally become the weak point of the entire water body, and the weak point in space is similar to this situation.

Now the question arises, if the astrologist wants to perceive the weak points of space, he must find the places with less "density", just like the fish living in the water, how can he find those points with less density?

If it is full of light, it may be possible to judge the water body in those places that is weak and the water body in which places is stable by the refraction path of light. However, space is to an astrologist what a body of water is to a fish in the dark.

That is, if there is no such aid as light...... For astromagicians, it's something like the law perception...... Then you can only rely on your own "feelings" to judge. This is undoubtedly a difficult thing to do, because fish themselves do not have the concept of water density differences, just as humans do not know that space is stable and weak.

In this way, the mental power of the Wizard must also be able to perceive the differences in space...... And this leads to a situation where the astrologer must first understand ...... At the very least, you need to understand some spatial concepts.

Generally speaking, without the guidance of famous teachers and the detailed explanation of the classics, it is impossible for those casual cultivators to figure out such a difference on their own. And Chen Linqiang is to Xin Yu, which is the light that guides him to quickly understand the difference between the interior of the space.

Actually, from this point of view...... Well, there are still some differences between the laws of space and the understanding of space, first of all, the laws of space are like detectors that assist astromagicians in understanding space...... And when the astrologist has mastered the laws of space, it is like a fish in the dark with night vision goggles, and can perceive the surrounding space more clearly.

And if the spiritual power of the astrologist can be so strong that he can perceive even a Planck length, that is, one ami, which is about equal to the smallest unit of space of one billionth of a nanometer, and this astrology can also distinguish the strength of space under this precision, it can be said that even if he does not understand the laws of space, he can also shuttle in any space with weak points.

Of course, what the law of space can do is not something that can be done with a strong perception ability, because the law of space not only includes the perception of the intensity of space, but also has other abilities for the effect of space...... For example, tearing apart a stable space in the most effortless way, and so on, is not something that can be done with strong perception.

In any case, Xin Yu now has the ability to roughly distinguish the spatial differences at the molecular level, that is, the sub-nanometer level accuracy, and with the guidance of a great star magician like Chen Linqiang, he will soon have the spatial strength difference in perceiving the sub-nanometer accuracy within a radius of several miles.

When he did this, the whole space seemed to him to be filled with countless "cow hairs", or filled with various dotted and mottled glass blocks...... Of course, when inside the planet, these weak points in space are not obvious due to the effect of space gravity...... Because the space is generally solid, the "diameter" of its weak point is itself small.

In this way, just like a person with weak eyesight who looks at the outside world through frosted glass, these "cow hairs" or "black spots" will become difficult to see clearly due to the blurring of perception. Without being able to perceive clearly, these spatial weaknesses are naturally impossible for astromagicians to use...... It is impossible to find a hole that can be torn, and the force required to tear the space is definitely much greater than tearing the space in the weak point.

Therefore, at present, like Xin Yu, who can still see the existence of "cow hair" in the space inside the planet, basically belongs to the ability that he had when he was in the high stage of Splitting the Sky...... From this point of view, the delicacy of the perception of spiritual power actually determines the ability of the Sky Splitting Star Magician to travel through space.

After being able to perceive the strength of the space, Xin Yu found a little helplessly that he knew that there were countless weak points in the space, and he could clearly perceive the specific direction, but when he released his spiritual power, and adjusted the frequency of the spiritual power that was ready to be used to tear the "crack" of the space to the frequency that Chen Linqiang showed when he tore the space, it seemed to be a hammer hitting the air, and there was no focus at all.

This question made Xin Yu very confused, after all, he clearly remembered that when Chen Linqiang tore the space into the subspace, he did use such a frequency...... Even the strength of the spiritual power did not dare to change, how could it not have an effect on the space?

Therefore, having a famous teacher to guide is far better than groping by yourself or even having a "strategy". Under Chen Linqiang's detailed explanation, Xin Yu realized that it turned out that these weak points of positive space were actually the "interfaces" connecting subspace.

...... To explain a little, in fact, whether it is positive space, anti-space, or subspace, it does not want to be physically oriented and has different coordinates. If we use the concept of three-dimensional coordinates to describe it, these three spaces are actually in the same "one place". That is, at any point in positive space, it is possible to correspond to antispace or subspace.

From here, it is necessary to introduce the concept of four-dimensional space or even multi-dimensional space, in the positive space or in the separate anti-space, subspace, it is true that the three-dimensional coordinate system can be used to determine the position of the object, but when these three spaces are juxtaposed, the astrologist needs to cross the space, and the concept of four-dimensional or multi-dimensional must be used...... Four-dimensional is to add a timeline, while multi-dimensional is to add some other axes.

Because subspace is a kind of chaotic nothingness that occurs after the "collision" of positive space and anti-space, it is natural that where the positive space and anti-space "blend" or "collide", there will be cracks that merge into subspace and point to subspace, or weak spots that have not yet had time to completely "heal and solidify".

And because the three-dimensional coordinate systems of the three spaces themselves are completely overlapping, the weakness of the space, that is, the so-called "interface", is embodied in the three-dimensional coordinates of the positive space, that is, randomly distributed in no corner of the positive space. And ordinary astromagicians or great astrologers also use such points to achieve the purpose of tearing the space into the subspace.

In this way, a problem arises, that is, the astrologist may be able to perceive these spatial cracks or weak points, but how to "widen" these cracks or "open up" the weak points of space with spiritual power is a very elaborate knowledge.

Widening the spatial rift actually acts on the positive space, and the "density" of the positive space itself is not uniform, naturally, if the astrologist wants to widen this small "spatial channel" that already exists, the force exerted must also resonate with the space around the rift.

If it can't resonate, it's just like using mental power to "dance" in space under normal circumstances, there is no "focus point" at all, and naturally it can't change the state of space.

And if it is not possible to form a resonance with the weak points of space, it is naturally impossible to penetrate these weak points, so as to achieve the purpose of opening up the passage or crack connected to the subspace.

In short, in a word, the frequency of spiritual power must form an absolute resonance with a certain spatial density at the space passage that needs to be opened, and in this way, every time you shuttle through space, you must need to release different frequencies of spiritual power.

When Chen Linqiang opened the space channel in space, the spatial rift he opened or widened was definitely different from the spatial intensity of Xin Yu's place...... If the frequency is different, it is naturally impossible to have an effect.

Therefore, Xin Yu's rote memorization of the frequency of the spiritual power released when Chen Linqiang opened the space channel, and then used it in the space he was in, is not in tune at all...... To put it in the words of the philosophers of Xin Yu's previous life, it is impossible for two leaves to be exactly the same in the world, and it is impossible for people to jump into the same river twice.

After understanding this, Xin Yu wondered, every time he shuttled through space, he had to determine the weak point or crack of the space that needed to be torn apart, and what kind of spiritual power frequency was needed to cross the space? Isn't it possible to use a kind of astral magic or spell to "automatically decode" this frequency to achieve a "fool-like" use effect?

In other words, there is no need to know the "parameters" of specific spatial cracks or weak points, and the "intelligent" ones release the spiritual power of the appropriate frequency?
