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.

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?"

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

"Ah Jiu, how are you doing after a year?" Li Ji may have been struck by lightning, and his brain was a little confused, but 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 swordsmanship, 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 in his heart, "Then can you see how he dealt with the thunder? I know you don't know the exercises, I mean, Wei Ji Shizu dealt with the thunder, did he use the flying sword to disperse it? Or did he have another way? For example, 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 disperse the thunder that had taken shape, there seemed to be a layer of shiny things on his body, and when the thunder light fell, it seemed to be ineffective for him?"

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

There are two very important pieces of information revealed in this sentence: did not disperse the thunder that had already formed? It means that the thunder that has already formed cannot be dispersed? Or, can it disperse the thunder before it was formed? Li Ji was actually negligent in this point, perhaps because he was a little nervous and did not 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...... What the hell is this?Magic?Vestment?Or something?

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 captured the first energy fluctuation, a void in the dark space, from birth to growth into a small thunderbolt, but three or four breaths of effort; with the first understanding, and then found that the formation of thunder has become much simpler, after observing many times, at the beginning of a void energy began to fluctuate, Li Ji a flying sword passed, 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.

What's more, as he continued to go deeper, the number and power of the meteorite group continued to increase, not to mention more and more powerful thunderbolts, so the question came back, what was that shiny thing? If he didn't figure this out, the depth of the thousand zhang was 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 also extremely true in this world, which also comes from Li Ji's habit of absorbing the local library every time he goes to a new environment.

Returning to the cave mansion, he continued to practice the Jingjing Sutra in the Yellow Court, the technique of the Six Senses, and 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.
