The change that Li Ji thought of was: coordinates.

The application of the divine soul in the cultivation world is mainly divided into two aspects.

First, perception, detection, this level of application has very little consumption of the divine soul, which is also the reason why most monks can maintain a minimum vigilance at almost any time, in this state, the recovery can keep up with the consumption, Li Ji called it the divine soul induction.

Second, the real use, just like a simple soul manipulation of the aerial subject, the magic of the law to cast spells, the sword cultivation of the flying sword, the control of alchemy, the concentration of the divine consciousness of the talisman, these consumption is obviously not in the same order of magnitude as the soul induction, it is impossible to rely on the recovery at any time to achieve the balance of the divine soul, and can only rest and operate the exercise recovery afterwards, Li Ji really called this the consumption of the divine soul.

Sword cultivation's divine soul consumption starts as soon as the flying sword comes out of the Mud Pill Palace, until it hits the opponent or is broken halfway, as the power of the flying sword increases, the faster the speed, and the farther the distance, this divine soul consumption also increases.

Li Ji's idea is to use the strength of the Divine Soul Induction, with himself as the origin, to establish a three-dimensional three-dimensional coordinate system, so that the flying sword will fly to the general direction of the other party according to the coordinates in the early and middle stages of rushing out of the Mud Pill Palace, and only at the end will he take over the flying sword at the level of divine soul consumption, so as to facilitate the final fine-tuning.

If everything goes well, releasing the sword in such a coordinate system, the Divine Soul consumption can be reduced by at least six or seventy percent, or even more.

This may be a great system, it may not be practical, and who knows until you practice it?

To do all this, the premise is to change the divine consciousness that you usually release into a three-dimensional coordinate system with yourself as the origin, and insist on using the coordinate system to observe the world every moment and every breath every day.

The second thing Li Ji wants to solve is the response to the thunder of the meteorite group, there is nothing to say about this, let's try it first.

A quarter of an hour later, Li Ji, who had a scorched black face, hair standing on end, and black smoke in several places in his robe, fled back to the original stone in embarrassment, fortunately, the thunder at a thousand feet was not very powerful, otherwise he Li Ji would have turned into a corpse and danced with the meteorite group.

Although the power of the thunder is not great, but the speed is incomparable, and it is extremely difficult to destroy on the physical level, although the speed of his flying sword is fast, but it has not yet reached the speed of sound, and the thunder is the speed of light, how can this compare? To describe Wang Ba chasing rabbits, he underestimated the huge gap between the two aspects.

After resting for a while, I felt that it was no different to go in again, and after nearly a year, Li Ji asked for help again, "Ah Jiu, is Ah Jiu here?" “

"Yes." Ah Jiu is still so sorry, fortunately it didn't laugh at Li Ji, maybe it can't understand such embarrassment?

"Ah Jiu, don't you have a good time?" Li Ji may have been struck by lightning, and his brain was a little confused, and he had a relationship with ordinary people.

"Let's talk about the point, don't talk nonsense, Ah Jiu has been like this for 10,000 years, don't you know?" Ah Jiu was very polite.

"Okay, what I want to ask is, when you watched Wei Ji Master Ancestor practice swords with your master, did you ever go out of the range?"

"The master watched him practice swords, and he watched it many times, most of them were thousands of zhang away, and the farthest one seemed to be three thousand zhang, as if it was."

Li Ji was overjoyed, "Then can you see how he responds to the thunder?" I know you don't know the exercises, I mean, Wei Ji Shi Ancestor used a flying sword to deal with thunder? Or is there another way? Like, absorb something. “

Ah Jiu was silent for a long time, as if recalling, Li Ji didn't urge it, and then Ah Jiu said, "I didn't see Wei Ji dispersing the formed thunder, there seems to be a layer of shiny things on his body, and when the thunder light falls, it doesn't seem to be effective for him?" “

This is a very valuable sentence, and after being determined repeatedly, Ah Jiu insisted on his memory.

There are two important messages revealed in this sentence: did not disperse the thunder that had already taken shape? Could it be that the formed thunder cannot be dispersed? Or, can you break up the thunder before it takes shape? Li Ji was actually negligent at this point, perhaps because he was a little nervous and didn't notice the process of the formation of thunder in the depths of the meteorite group.

The second important piece of information is: a layer of shiny things, Ah Jiu can't tell what it is, and he can't even remember what color it is, but when Li Ji showed his sword trick, Ah Jiu made it clear that it wasn't this layer of things...... Sparkling? What the hell is this? Magic? Cassock? Or something else?

Li Ji decided to confirm the first point first, the formation process of thunder.

He wandered in the meteorite group at a depth of thousands of zhang, but most of his attention was on the distance of the meteorite, but fortunately, he was able to deal with the attack of the meteorite group at this location, so he was able to free up most of his divine sense for exploration, and every trace of energy fluctuation in the space outside the thousand zhang.

Soon, he caught the first energy fluctuation, a void in the dark space, from birth to growth into a small thunderbolt, but only three or four breaths; With the first understanding, I found that the formation of the thunder became much simpler, and after observing it many times, at the beginning of a void energy that began to fluctuate, Li Ji passed by a flying sword and successfully destroyed the formation of this thunder.

…… Li Ji once again returned to the original stone with a disgraced face, and successfully interrupting the formation of thunder could not help him continue to go deeper, because after dealing with countless meteorite groups, he really couldn't spare his hand to interrupt more thunder formation, unless he could breathe out twenty swords, thirty swords, obviously, this was impossible.

More importantly, as it continues to go deeper, the number and power of meteorite groups continue to increase; Not to mention more powerful thunderbolts; So, the question comes back, what exactly is that shiny thing? If he didn't figure this out, the depths of a thousand zhang were his limit, and the Nine Palace Realm could no longer provide him with a more effective cultivation environment.

Time has passed in cultivation like this, and now it has been a year since the last time the Nine Palace Realm was opened, and the time multiplier has only really reached ten times now, Li Ji has plenty of time to practice the technique, to build and maintain the coordinate system, and to guess the origin of that layer of bright crystal.

Fortunately, over the years, Li Ji, who is very familiar with Fan Lou's book, has a vague and preliminary judgment.

Knowledge is power, and this saying is equally true in this world; This also stems from the fact that every time Li Ji comes to a new environment, he will learn from the local library.

returned to the cave mansion and continued to practice the Jingjing Sutra in the Yellow Garden, the technique of the Six Senses; Early in the morning of the second day, Li Ji, who had finished his homework, did not rush to enter the Nine Palace Realm, but went straight to the Fan Tower of Wen Guangfeng Tianxuan Hall.

Here, perhaps, he will find the answer.
