With the martial arts strength of about eight grades after two extreme realms, the one-handed strength has increased to nearly thirteen,000 times that of ordinary top professional warriors, about 1,500 tons of strength, and the ordinary soil no longer feels like the previous thin mud, but more like some kind of liquid. He seems to be able to "dive" like a fish at a speed of several meters per second. The ordinary military steel and even granite, which seemed to take a lot of effort before, felt like a little harder mud in his hands.

Even so, in order to avoid too much movement, Zhang Fan still cautiously "dived" in the gap between the underground granite and the aquifer at a speed that did not exceed the limit of mortal swimming at a speed that was not too fast, and constantly tried to restore the soil layer to its original state behind him with superb mental power and even internal qi means, so it took about ten hours to reach a distance of two hundred miles, and Zhang Fan poked his head out slightly in the dark night.

Then, in the dark night, the surface of the earth quietly flew a distance of more than six hundred miles at a level that did not exceed the level of the top masters of the ordinary inner gate, and quietly dived into the earth again and cautiously traveled a long distance in a place where the underground water source was relatively abundant and very suitable for concealment detected by spiritual power perception

This time, Zhang Fan was not sloppy, and spent about ten days away from the previous city for more than 5,000 miles before finally determining the place to settle down, which was about a thousand meters deep under a high mountain, and the temperature seemed to be very high. According to Zhang Fan's estimate, as long as he is not good at some special exercises, even if he is a strong person at the peak of foundation building or an ordinary golden pill that is not too much higher than that level, it should be difficult to find his figure, so he finally settled down and took out the Qiankun shield and escaped into the shield.

At this time, it seems that thirteen years have passed in the time in the shield, and even ordinary people who are not particularly good in eyesight should be able to see that the hundred-year-old spirit gathering grass has changed slightly. The Qi Gathering Pill only maintains its original quality and does not deteriorate.

Of course, Zhang Fan didn't dare to rashly take the Qi Gathering Pill refined by the seventy years of Qi Gathering Grass, although the senses given by the Venerable Lord of Luoyun Mountain were not bad, but after all, people's hearts were separated from their stomachs, and they didn't know how to do things. If there is any more back-up, I am afraid that I will face a lot of trouble in the future. What's more, the internal qi of the martial arts is not his weak point for the time being, and the spiritual power that has not yet entered the realm of qi refining is his biggest weak item without a spiritual root. Therefore, Zhang Fan was not in a hurry to do anything to the Qi Gathering Pill.

From then on, Zhang Fan spent about 20% of his time adjusting and correcting, about 20% of his time cultivating internal qi, about 20% of his time cultivating spiritual power, and about 40% of his time spent on spiritual power training.

In the patient cultivation, the days in the Qiankun Shield flickered, and seventeen years passed, and the spirit stone spiritual liquid, which was still very rich before, obviously began to become a little weaker under the absorption of the Gathering Spirit Grass, and the speed of the spiritual energy release also decreased greatly. Zhang Fan used the original method to crush a few more spirit stones and put them into the spiritual liquid.

What Zhang Fan didn't expect at first was that after the smoke-like green gas that these spirit stones turned into after crushing was merged into the spiritual liquid, the spiritual energy emitted by the entire spiritual stone spiritual liquid began to soar, obviously exceeding the time when this kind of spiritual energy release speed was comparable to that of medium-grade spiritual stones at the beginning. Of course, Zhang Fan also guessed one or two later: his spiritual power had entered the realm of the purple soul ring, his internal force cultivation had reached the level of the eleventh grade of the transformation realm, and his spiritual power had reached the level of about thirty-six levels. The spirit stones crushed by the CO2 ultrasonic method were obviously of higher quality than the previous one. According to Zhang Fan's careful observation of his spiritual power at this time, the fineness of the spirit stone powder fused this time should be at the level of about ten nanometers or one hundredth of a micron. The effect of three broken walnut-sized spirit stones is almost equal to the effect brought by the original ten broken spirit stones.

In this case, not only did the Gathering Spirit Grass begin to become more luster, but he also gained tremendous benefits in the cultivation of spiritual power and even spiritual power. Originally, after entering the level of spiritual power of the Purple Soul Ring Warlock, the spiritual power cultivation speed had decreased, and this time it seemed to have been significantly replenished.

Of course, the total spiritual power of each spirit stone seems to be limited, and when the speed of releasing spiritual energy reaches several times that of the previous and dozens of times the normal speed, it is only about ten years before that the speed of the release of these spirit stones begins to decline. In order to ensure the quality, Zhang Fan began to crush a spirit stone to a smoke cloud powder state of about three nanometers with a higher quality after he entered the spiritual power cultivation of the Red Soul Ring Warlock at this time and had about thirty-seven levels of spiritual power, once again restoring the spirit stone to its original release speed.

In this way, from the beginning of entering the Qiankun Shield, in the thirty-second year, Zhang Fan began to encounter the first bottleneck. After entering the spiritual power level of the Red Soul Ring Warlock for a full six years, Zhang Fan finally began to gradually feel some kind of bottleneck. Although his spiritual power is already thirty-eight order, it is comparable to the late stage of Jindan monks, and it is unique among the lower-level spiritual power monks. However, without a spiritual root, it is obviously a huge threshold obstacle to break through the bottleneck of the Qi Refining Realm. This time, Zhang Fan smashed ten spirit stone fragments with all his strength to the level of one nanometer of dust, and the unprecedented spiritual power in the spiritual liquid began to form a layer of green bright light around it, and the spiritual energy also emitted at an unprecedented speed at this time. For the next three months or so, Zhang Fan did not waste the slightest time and devoted himself to spiritual power cultivation. Suddenly, his spiritual power changed from crimson to golden with orange red, Zhang Fan began to understand from some knowledge he learned from the library: this is because he forcibly broke through without a spiritual root and reached the extreme realm above a certain red soul ring warlock, after this realm was gradually consolidated for three years, Zhang Fan made up his mind to put twenty spirit stone fragments into the liquid configuration again at one time, so that the aura release speed of the entire spiritual liquid began to exceed that of some legendary commercial spirit stones, and controlled the spiritual power with strong spiritual power to enter his limbs and hundreds of remains。

It took about another three months or so, and just after his spiritual power began to enter the level of about thirty-nine steps, the orange red in the golden yellow of the external spiritual magic became lighter and thinner, turning into a complete golden light, and finally the golden light began to glow with a green like a spirit stone spiritual liquid, and this green accelerated to become vigorous, and finally let the color of the spiritual power near his body and the color of the spiritual ornament spiritual liquid absorbed into his body merge into one. When his spiritual power reached the peak of Jindan, and at the same time, he overdrew the threshold of the Qi refining realm.

At this time, Zhang Fan roughly tried one or two, now he doesn't need to use special tools and spend too long, he can form a thunderball with a certain power in his hand with the actual combat spiritual technique, and the thunder and lightning seem to come from the air with strong spiritual power in the Qiankun shield.

Of course, Zhang Fan also roughly estimated it at this time: if he only used the traditional way to fight with people at this time, because of the lack of some special spells, although the spiritual power was very strong, at most he could only be with ordinary qualified monks at the peak of qi refining, and the fundamental improvement of combat effectiveness was of course with the help of special tools. The power of the Divine Thunder Cannon Warhead will undoubtedly increase by a step from now on.
