According to Zhang Fan's rough estimate, from the level of spiritual power that the white soul ring warlock has just entered the realm of qi refining, the theoretical combat power value should be increased to two and a half times the original, about ninety million times, which is equivalent to a perfect formation between nine thousand and ten thousand people. It is estimated that the combat power advantage of a beginner martial artist like a sweeping monk over an ordinary professional martial artist is similar, and it should be far less than the advantage of the junior god in "Douluo Continent" over the white soul ring soul warrior, perhaps there is no martial soul and natal true body in this plane, so those spirit warlocks are obviously much weaker in the middle and high levels.

It's just that he only uses one aspect of spiritual art, not as the main combat power, so after reaching the high-level spiritual power, the power of the thunderball warhead that can be stably condensed will be increased to about four or five hundred times the original, and the increase in combat power is about equivalent to the improvement of only three foundation building grades.

Zhang Fan roughly estimated: Now his materials are not enough, and he can't give full play to the strength of the Divine Thunder Cannon and the Qiankun Shield, but even so, if he encounters a master at the peak of foundation building, he should be able to kill it more calmly and directly, and he doesn't need to control the Qiankun Shield to overdraw all his combat strength as before. If you have to fight like that when necessary, you should be sure to deal with an opponent with the strength of Jindan's first and second grades.

Of course, even so, Zhang Fan didn't feel that it was safe for him to rush out of the Qiankun shield now. Because the effectiveness of foreign objects in dealing with raids and even special situations is still somewhat limited. If he only relies on the means of transforming internal qi and spiritual power to fight, it is estimated that he can only fight with the masters of the non-spiritual power system above and below the eight grades of the foundation.

Therefore, starting from the thirty-seventh year after entering the Qiankun Shield this time, Zhang Fan temporarily shifted the direction of improving his combat effectiveness to the cultivation of internal qi. The speed at which the aura can increase the cultivation speed of the internal qi is limited, so Zhang Fan did not waste the spirit stone in the cultivation of the internal qi for the time being. However, in order to be able to try the effect when facing a breakthrough bottleneck, Zhang Fan still cultivated at a normal rhythm using a concentration equivalent to the spiritual liquid of twelve spirit stone fragments when his internal qi cultivation was on the verge of reaching the threshold of the twelve spirit stone fragments, and in this case, it seemed that some of the bottlenecks he had felt had gradually been opened. After entering the Qiankun Shield, his internal qi finally broke through the bottleneck and entered the realm of heaven and man, which is equivalent to the foundation level.

If to a large extent, the realm of transformation martial arts is only the accumulation of internal force to a certain extent and begins to have some qualitative impact on the body, then the realm of heaven and man is to a large extent the integration of spiritual power and internal force. Zhang Fan found that although after entering the realm of heaven and man, aura could still only play a very limited role in the improvement of martial arts cultivation, but because he had reached about thirty-nine levels of spiritual power, the cultivation of cultivation strength was much smoother than before. It took only about fifteen years to cross most of the Heavenly and Human Realm, and reached the strength of the Heavenly and Human Realm Martial Dao Eleventh Rank, which was equivalent to the strength of a monk of the ninth rank of the Foundation Building.

At this time, Zhang Fan suddenly discovered that some hidden dangers that he had estimated before also came at this time. Perhaps because he had to absorb some energy that was not very suitable for him when he was fighting with the monk named Ouyang Jian, the threshold of the Heavenly Man or the equivalent of the Foundation Building Realm had finally arrived. According to the saying: A monk who can cultivate to this extent can break through to the equivalent of the Shattered Void Realm in the martial arts, which can be described as one in a thousand. Zhang Fan also realized that if there was not much chance, his realm in the martial arts would probably stop at the level of the eleventh rank of heaven and man or at most the twelfth rank of heaven and man.

According to Zhang Fan's thoughts: If a confidant can continue to obtain the spirit stone spirit liquid, I wonder if it can raise the spirit gathering grass to the standard of more than three hundred years or even a thousand years? If I was taking the spirit gathering grass at that time, and my cultivation in other aspects was unprecedentedly improved, I don't know if it could play a role. The world is so big, as long as there is enough strength, I believe that there may not be a lack of such opportunities. The same soldier may be difficult for ordinary martial artists in the realm of heaven and man, but it may be a different matter for people with completely different levels of identity?

At this time, it happened that the Gathering Spirit Grass also began to change a little, and the originally lush green color seemed to have begun to have some instability, and a faint yellow qi penetrated through it. Zhang Fan didn't dare to be too stingy at this time, and began to make sub-nanometer size spirit stone fragments and smoke clouds with his attainments at this time and integrated them into the spiritual liquid, so that the release speed of the spiritual energy was ten times that of the original, and once again formed a green light curtain that enveloped the entire plant, and the yellow qi seemed to be temporarily suppressed.

In this way, the second time there was a little bit of a similar sign, Zhang Fan threw a spirit stone fragment after the shattering of the smoke cloud substance to strengthen the concentration so that the spirit grass always maintained its vitality, and finally Zhang Fan had to speed up the use of spirit stone fragments, until the full use of twenty-one spirit stone fragments, the spirit gathering grass that once seemed to be in crisis was rejuvenated.

This time, the Gathering Spirit Grass for two hundred years was not a catastrophe at all, and the "Two Hundred Years Tribulation" cost twenty-one spirit stone fragments, which made Zhang Fan have to start reconsidering some thoughts: The Three Hundred Years Tribulation seems to be a kind of spirit grass pass that was mentioned in the books of the library building during the brief introduction. It is said that there is a certain chance of spending it only in some places where the aura is particularly strong. The millennium is another elixir, the millennium elixir will cause a thunderstorm that is not too big, and the millennium elixir after the thunderstorm will have spiritual intelligence. Of course, Zhang Fan didn't plan to raise this Gathering Spirit Grass for more than a thousand years, which would only add any trouble or trouble. I plan to make it my own help when I am seven or eight hundred years old. However, will this three-hundred-year pass consume too many of his spiritual energy spirit stones, so that it will affect his spiritual power cultivation in the future and even some combat uses of the Qiankun shield itself?

Thinking of this, Zhang Fan felt that he didn't need to cultivate in the Qiankun Shield for about a hundred years, and then spend about twenty years to consolidate the strength based on spiritual power, so he should go out and find some materials and even some people's mold. After entering the realm of heaven and man, Zhang Fan, whose theoretical healthy life expectancy increased to about 600 years old, became a teenager who looked like him at about 15 or 6 years old. Twenty years later, his appearance should be similar to that of his previous ordinary light years, and it will not make people doubt in vain.

In this way, in the following twenty years or so, Zhang Fan began to refocus his cultivation on the spiritual energy itself after his internal qi and martial arts cultivation and spiritual power reached a certain limit.

Because of his super high spiritual power and the assistance of the spirit stone spiritual liquid, Zhang Fan's spiritual power cultivation in this area soon improved to the level of about eight grades of the authentic qi refining realm. Even if it is just a random thunder technique without using any tools and authentic spells, it may be able to match the self before entering the Qiankun Shield. In this case, Zhang Fan had a plan to prepare to go out of the customs.

According to the rough calculation, even if he encounters the siege of many masters at the peak of foundation building at this time, he should be able to at least escape calmly by just using his own ability without exposing the Qiankun Shield? Even if he is facing some Jindan middle and early stage masters, he may be able to have a more reliable sense of danger with his spiritual power at this time? In this case, his survivability is undoubtedly not comparable to what he was before.
