After experiencing a big battle in the Qiankun Shield, Zhang Fan no longer always stuck to the Qiankun Shield when flying in order to save his life, but he began to overdraw more cooling water to seek a higher speed, even so, after reaching about thirty times the speed of sound, he seemed to have encountered some kind of extreme bottleneck, and had to use the time in the Qiankun Shield to make wind and heat avoidance charms, while hurrying at the fastest speed. In the following two months or so, Zhang Fan successively came to three places where the fourth-order demon beasts were relatively concentrated, and there were a few fifth-order demon beasts to sweep. It seems that the previous great tribulation and pass overdrafted the bad luck, or maybe it was because his perception was more sensitive after entering the fortieth level of spiritual power, so he didn't encounter any major problems. In the case that he also possessed a certain degree of illusion confrontation ability, it was easy for him to have a four-thousand-ton equivalent divine thunder cannonball that safely swept away one hundred and two fourth-order demon beasts in successive stages. The choice of these targets is not based on spiritual power, but on fourth-order demon beasts such as the Dragon Snake, the Ming Corpse, and the Xuangang Tree Monster, which are mainly based on their strong physical combat ability. Of course, there are also three fifth-level powerhouses who are comparable to the peak level of Jindan, such as the Dragon Snake King, the Ming Corpse King, and the Xuangang Tree King.

Previously, Zhang Fan's idea was that those demon beasts with a spiritual power system might be beneficial to improving his spiritual power and spiritual power, and they would be easier to deal with, but in the end, he felt that this might not be the case. Those demon beasts of the spiritual power system are obviously much more intelligent, and the most important thing is that they "don't follow the routine", if they run into a demon beast of the seventh-order spiritual power system again, will they still have the same luck as before? Moreover, Zhang Fan found that the spiritual power and spiritual power possessed by many demon beasts of the spiritual power system do not seem to be all the way to himself, and their soul cores do not seem to be pure energy, and they cannot safely use or directly obtain any benefits for themselves. And the hardest part of the body material of these "hardcore demon beasts" with relatively strong bodies is obviously a good material for refining armor and powering aviation hair. Now his attack power is not bad, and his mental power is still in the past and there is a lot of room for improvement. However, its own strength, especially its defense, is obviously still a hard flaw.

In order to ensure that the risk would be further reduced in the next round of operations, Zhang Fan first began to try to refine a suitable integrated armor using the hardest core bones of the corpses of the Ming Corpse King and the Xuangang Tree King, with a total weight of about 100 kilograms. According to Zhang Fan's rough estimate, the strength of these materials is about 10 million times that of ordinary steel and tens of thousands of times that of quasi-Xuangang. Even with Zhang Fan's strength at this time, even if it is directly processed with hard objects such as the mysterious short sword or even the Qiankun shield, it seems to be extremely difficult, and the final choice can only be to select one or several equally hard bones as the "warhead" in the Shenlei Cannon shell, and constantly "smash" through the accurate firing of the medium-sized Shenlei Cannon to "smash" the method of making stone tools to forge in the Qiankun Shield.

The difficulty and effort required are simply unimaginable to ordinary people, even with Zhang Fan's fortieth-level spiritual power and even good cultivation at this time, he has been busy in the Qiankun Shield for about three years, and has carried out millions of collisions and fires, before finally forming a combined plate armor-like armor. After some actual combat exercises in the Qiankun shield, the thickness distribution of this armor is probably the strongest place in the back of the head, neck, back, and ribs. The limbs and even the front are much weaker. Because monks are different from ordinary mortals, if a small wound on the calf of an ordinary ancient soldier is not noticed, it is possible to bleed to death in a long-term confrontation and battle, and for monks in the foundation building period and above, being cut into a human is only a general attritional injury, and it can be good for a few days of cultivation. Moreover, in the virtual drill simulation in the fantasy world: because the front is the most focused part, the probability of hitting in the face of various dangers is the smallest, and there is also a Qiankun shield responsible for protection.

Therefore, the entire armor also presents a "key protection layout" with strong back and head defense, and slightly worse limbs and front protection. In verification: The defensive effect of this armor against physical attacks or general transformation strength attacks is basically equivalent to the fourth layer of the Jindan peak, which is about the protective strength of the thirteenth grade of Jindan. After having these protective means, Zhang Fan roughly estimated that his combat effectiveness at this time had also increased by at least three grades. With the various means he has at this time, and even some of the protective talismans he has made, even if he encounters an ordinary opponent at the threshold of the Yuan Infant, he should be able to win steadily, and the seventh-order ghost before encountering it is of course another matter, but it should not be the same as before.

Just these, of course, Zhang Fan didn't think that he could relieve himself of potential danger, because if the true situation in the Qiankun Shield was leaked, the master he might face would probably be much more powerful than that seventh-order ghost.

Therefore, after all this was over, Zhang Fan first started his retreat cultivation again, and the substance made by using the nine hundred spirit stone fragments to further crush it seemed to have begun to possess some characteristics of "qi", not just a tenth of a micron of dust, and the effect of the spiritual liquid seemed to have begun to strengthen significantly. In order to break through the small threshold from the Nine Grades of Foundation Building to the Peak of Foundation Building, Zhang Fan had to start trying to use some of the branches and leaves of the Spirit Gathering Grass that had survived the three hundred years of tribulation to enter his body for assistance and assistance.

With the help of the rich aura and even the three-hundred-year-old Gathering Spirit Grass, Zhang Fan finally broke through the small threshold between the ninth grade of foundation building and the peak of foundation building, and continued to start the cultivation process within the Qiankun Shield.

Compared to the last retreat, which was a grade of a few years, this time the pace of progress was significantly slower under more favorable conditions. The hard wound of the spirit root, even if it is the spiritual power of the Yuan Infant level, the part of the three-hundred-year-old spirit gathering grass, and the nourishment of the spiritual liquid that is not bad, it cannot be completely compensated. Progressing from the first level of the foundation building peak to the second level almost made Zhang Fan spend a generation of twenty years in the Qiankun Shield, and it took thirty years to progress to the third layer, and when he reached the fourth level of the foundation building peak, a hundred years had passed. Zhang Fan looked like a middle-aged man in his forties at this time.

There seems to be a saying in the mundane world that "fifty knows the destiny of heaven". The same is generally true in the cultivation world, if you don't make an important breakthrough when you are nearly half a hundred years old or halfway through your life, it is very likely that you will not be able to progress to the next level in your life. Only a handful of unpredictable super-chances can change this fate. Therefore, when the Gathering Spirit Grass had broken through four hundred years and had been possessed at the most, the more than 1,000 and hundreds of lower-grade spirit stone fragments were exhausted in cultivation, Zhang Fan also had to start taking the risk, risking that in the end, there was still not much to gain, and the Gathering Spirit Grass was smashed one by one with unique means in a not too long time, and with super spiritual power, he could identify the impurities in it and remove the impurities in it. Although he didn't have a furnace ding and was not proficient in refining medicine, relying on the absolute spiritual power level advantage, Zhang Fan finally absorbed the entire Gathering Spirit Grass to the maximum extent by refining the essence. Zhang Fan didn't let him wait until the Gathering Spirit Grass was more than five hundred years old, first, the time seemed to be a little tight at this time, and second, according to Zhang Fan's previous understanding, although the five hundred years of Gathering Spirit Grass did not have the spiritual intelligence of high-level animals, it also began to have many signs of life. Zhang Fan was not willing to overdraw this kind of life in order to bury any hidden dangers for possible cultivation in the future.

When the essence of this Gathering Spirit Grass was transmitted into the limbs and hundreds of bones by means of unique spiritual power internal qi, and gradually converged in the sea of qi, a green ball of light began to gradually form in the position of the sea of qi, and finally many meridians in the body seemed to begin to become useless, and the whole body began to undergo some changes. And Zhang Fan's age seems to have gradually stopped passing quietly at this time. In the following decades, the golden yellow of the internal qi in the cultivation became more and more, and finally it seemed that almost all the spiritual qi on the outside had turned from blue to golden color, and Zhang Fanyuan's original appearance gradually returned to his youth from middle age, and when all this dust settled, Zhang Fan's heart was initially relaxed.

A series of cultivations have increased his original strength to about 4,000 times the comprehensive strength of the original six foundation building grades and above, and relying on the bonus brought by the refining "Three Bone Armor" protective power to form the improvement of the strength of the three foundation building grades and above, plus the spiritual power and even the use of illusion have also improved a lot, the entire strength has once again risen to a big level, and Zhang Fan finally has the confidence to deal with some stronger risks.

When the march began again, because he began to have the ability to control heat with spiritual means and heat dissipation charms, and when he used the Qiankun shield to fly, the speed was also greatly increased compared to before, reaching nearly 100 times the speed of sound, and the distance of 2.9 million kilometers and five or six million miles per day was about 5 or 6 million miles. Moreover, in the case of flying at such a speed in actual combat, there are many ways to hide the traces of his too obvious high-speed movement when the flight altitude is not very large, which is the actual result of the spiritual power after entering the fortieth order.

Zhang Fan's destination this time was the habitat of a fifth-order demon beast "Lightning Dragon" in the "50 Million Miles of General Knowledge" map, which was also located near the edge of the entire map. According to previous experience, the so-called "Land of X-Order Demon Beasts" is bound to deal with the preparation of sixth-order demon beasts because of the time of the map and even the expiration date, and it is not impossible to encounter seventh-order shape-transforming demon beasts. In the face of this kind of dangerous place, Zhang Fan may have had concerns in the past, but his confidence at this time is undoubtedly much stronger.
