In order to test the hardness of this core stone, Xu Jianxing took a few steps forward and got another piece, and then after using seven points of strength, Xu Jianxing found that his pure strength that could be crushed even by ordinary materials of the ninth grade, at this moment, it was also on the top of the core stone, leaving a white mark.

Looking at such a situation, Xu Jianxing was overjoyed, according to his estimate, this core stone has at least reached the level of demigod-level materials, maybe it is directly god-level, although the Qiankun Great Sage has brought him a lot of materials, but those materials, Xu Jianxing can not move or does not want to move, not to mention, some things are in vain, and through his own acquisition are fundamentally two concepts.

And the most important point is that the profession of mining will inevitably be vividly revealed here, and it can also save him countless time. As for the danger, Xu Jianxing didn't think too much about it, because, although he didn't have many defensive artifacts in his hands, he also had more than 1,000 pieces, and even if one could support half a month, he could resist for nearly fifty years, not to mention, he still had all kinds of magical pills in his hands, as well as the furs of many immortal stage monsters, the furs of these monsters, even if they were not made, were equivalent to the best immortal artifact grade items, if they were casually played, even if they couldn't reach the semi-artifact, they wouldn't be much different. In this way, Xu Jianxing believes that staying in this area for thousands of years is a small matter.

Of course, if Xu Jianxing was really allowed to stay here for a thousand years, he was afraid that he would have to go crazy. It's not a good place after all. Maybe you will die in an accident, after all, this is not a stable area at first glance. That changes at one point. It's not too normal. And if he fell into the lava, things would be really unpredictable.

Next, Xu Jianxing carefully began to explore in this huge magma cave, and in the process of exploring, Xu Jianxing did not forget to collect the ore, maybe carefully dig a few pieces of ore that are easier to dig, and as he digs out a piece of ore each time. Then there will be a small jump in the experience of mining.

At this time, Xu Jianxing's dantian will also give birth to a star element out of thin air, although these star elements cannot support Xu Jianxing's external consumption, but it has also alleviated a lot.

It was not long after I explored it.

Xu Jianxing found that there was no way to go in this direction, which made Xu Jianxing feel painful, there may be a place to go in other directions, but it is not a matter to go around like this.

It's not that there's really no way out, it's just that the road is over the rock wall where the narrow lava flow flows. But Xu Jianxing can't always pass over the stone wall above, and if he does, he can. It's really tired and crooked, after all, the stone wall is too hard, looking at the magma flow channel is only one person high, although he can suck the stone wall to death after using Xingyuan, but in the scorching heat of this terrifying heat, it is also consumed, and if this road is very long, then it is not looking for death at the end of the road.

As for the idea of opening a hole directly and walking towards it, Xu Jianxing didn't think much about it at all, because, if he did that, if there was a magma flow somewhere above, then he would really have nowhere to escape, if the movement was at a big point, he would be directly submerged in it, which was a very normal thing, so where did Xu Jianxing dare to open a hole here. Even if it will be opened later, there is no way to do it.

Subsequently, Xu Jianxing didn't think much about it, so he changed the direction, in the process of changing, Xu Jianxing naturally did not forget to collect the ore on the ground, however, Xu Jianxing only collected relatively simple ones, like those that are really difficult to get out, Xu Jianxing is not moving, at this time, he is still trying to find a way to leave, if he can leave, in the future, it should not be difficult to come here.

The reason why Xu Jianxing has this idea is naturally because of the somersault cloud, and now, Xu Jianxing has also discovered the biggest drawback of the somersault cloud, this disadvantage is that it is easier for him to go anywhere, but it becomes very difficult to get out, as if a person deliberately dug a pit for him to jump, and after the jump, he didn't care. If you want to figure it out, you can only find the rope yourself.

After a while, Xu Jianxing's eyes lit up, because he found a small stone island in the center of a magma flow, this small stone island only emitted red light under the illumination of magma, and its appearance was not good, but Xu Jianxing knew very well that there must be another mystery in this, otherwise, in such a magma flow, how could there be a small stone island, what is this small island as if it is absorbing the heat of the magma flow, and if it is left in the outside world, don't say this small stone island, Even if it is a million-zhang high mountain of gold and silver, in a moment's effort, I am afraid that it will be melted away.

After a little thought, a small flame like a thin hair emerged from Xu Jianxing's hand, and then Xu Jianxing carefully threw it outside, the main reason why Xu Jianxing had this move was that considering the factors of different regions, and according to his understanding, in some regions, a small spell of the same attribute would be infinitely magnified, and this is also the kind of region that will be magnified. The only difference Xu Jianxing is to know how many times this spell will be magnified, and what kind of performance it will have, if the performance is appropriate, he can use a little bit of strength to catch that little stone island.

However, there must be two prerequisites in this, one of them is that it must be the true fire of the origin in order to achieve this condition, if it is a different kind of abnormal fire, it can only make the two incompatible, exploding, of course, if you cultivate high enough, this problem will not appear, and second, you must put the divine consciousness outside, hook the surrounding breath, and there is still a great danger in this, the danger is that the divine consciousness is not well controlled, it will make the qi of a certain attribute in the outside world become more violent. That's why Xu Jianxing's movements are so careful.

Xu Jianxing threw a small flame outside, and at the same time forcibly endured the flame outside that seemed to be able to burn spiritual consciousness, so he slightly communicated with the qi of heaven and earth, and when Xu Jianxing used the qi of heaven and earth to communicate with the small flame slightly, the boundless fire element instantly crowded over, suddenly turning the small flame into a big fireball. In an instant, it was the size of a basin.

"Nima ......" see here. Xu Jianxing's face was full of shock. How much spiritual power did he use, he knew that if he put these spiritual powers outside, at most they could be ignited into a flame smaller than a match, where did he ever think that after coming here, it would be so terrifying, I'm afraid. More than 10,000 times.

In Xu Jianxing's thoughts, the basin-sized fireball became the size of an ordinary round tabletop, and then in the annotation of Xu Jianxing's gaze, the fireball the size of the round tabletop trembled sharply, almost trembling like this, and the huge fireball exploded with a bang.

How strong the explosion was, Xu Jianxing was not very clear, when the terrifying flame breath. When he roared towards him, Xu Jianxing hurriedly retreated. Instantly retreated to a place with nowhere to retreat, and the sparks that exploded sprayed everywhere, suddenly setting off a muffled sound of banging, the only thing that was okay was that these sparks did not cause much damage to the stone wall, otherwise, what would happen, Xu Jianxing himself didn't know what to do, but even so, Xu Jianxing also sensed that the flames that were slightly sprayed outside the artifact's shield made the light of the artifact's defense dim a little.

"Whew!" Xu Jianxing took a light breath and said, ", it's too scary." ”

Subsequently, Xu Jianxing used metallic properties, fire attributes, and spells of various other attributes, and tested it here for a small time, and after the most lucrative time, he learned that no matter what kind of spell was used, the effect that could be played here was very small, so small that he did not use even a trace of heaven and earth vitality, only his own star element was in play, and the water attribute was the most, after all, the two existed in this mutual restraint, as for the wood attribute spell, it was to fuel some arrogance, but, The arrogance that fueled is almost negligible here, who made the true fire of the earth here already strong to the point of unknown.

After the test was completed, Xu Jianxing began to carry out the next experiment, which was to see how many fire elements were hooked up, so as to reach the point where the heart could walk at will.

Don't look at Xu Jianxing's simple experiment, but if it doesn't reach a common rhythm with the flame breath here, it is impossible to borrow power, just like the people in the real world are all human, but the fluctuation of the magnetic field is completely different, and the flame breath of this fairy world is naturally the same, even if Xu Jianxing reaches the point of rhythmic balance after the most reluctance, he can only fight with force, but he can't help but let the flame breath here hurt him. Unless, the fire system law that Xu Jianxing comprehended was higher than the flame intensity here.

In this way, three days have passed, Xu Jianxing can be regarded as having reached a delicate balance between his fire spell and the flame law aura here, in fact, if you talk about it, Xu Jianxing has a simpler way, that is, to absorb the flame breath here for his own use, and then slowly comprehend, although Xu Jianxing will suffer some hardships in this, but with the situation that the earth pole true fire itself belongs to the origin fire law, there will always be a successful day.

But here comes the problem again, if he comprehends the true fire of the earth here, then when he reaches the worst, he will definitely ascend, and the last thing Xu Jianxing wants to do is to ascend, after all, this not only involves the experience of adventurers, but also involves more unknown things, and, in this, if he is not careful, he will also be very self-immolated, who let, when he perceives something, he must devote himself wholeheartedly, if he is distracted to do it, then if there is no accident in an accident, there will be ghosts.

Not to mention, there are other unknown circumstances that will happen, such as the collapse of the cave caused by the hedge of the fire flow and other local fire flows, such as the very consumption of star elements, and so on. Therefore, the best way to do this is to escape and find a safe place to come.

However, even so, after Xu Jianxing was busy with the balance of the fire method, he still carefully used a small amount of earth pole true fire to cultivate for some time, after all, no matter what, this has a lot of benefits for his safety, and it can also make Xingyuan consume less, and Xu Jianxing is also mentally prepared for a protracted battle.

The reason why Xu Jianxing has this preparation is because he knows very well in his heart that this underground Polar True Fire World Realm must be like a huge labyrinth, intricate, maybe it is possible to return to the original point after walking for a long time, you said that in that case, how could Xu Jianxing be able to come out so easily, and in Xu Jianxing's thoughts, the catastrophe he is going to go through this time is not the polar true fire, I am afraid, the main thing is the maze.

Of course, to say that the polar true fire is not a little threatened, it is simply impossible, after all, the instability of the underground world is almost a matter that people know. According to legend, there are still all kinds of strange creatures living in the underground world, and as for whether it is or not, Xu Jianxing does not know the way.

In the blink of an eye, more than ten days have passed.

As soon as ten days passed, Xu Jianxing changed a defensive artifact on his body, as for the original one, Xu Jianxing was included in the space, although this artifact was damaged to a certain extent, but the problem was not too big, I think that under the nourishment of the aura in the space, after a few years, it can be recovered. And the artifact is in a way, exactly like the situation of a monk when he is injured,

When everything was ready, Xu Jianxing calmed down his mood, that is, he carefully ran the exercises, and suddenly an invisible flame hand appeared out of thin air, and in an instant, this flame hand grabbed towards the island in the magma flow.

A grab falls. Xu Jianxing was dumbfounded, because this endless flame qi was actually absorbed by Xiaoshidao, and there was not a drop left.

Immediately after, Xu Jianxing smiled dumbly after thinking about it again, after all, since this inconspicuous island of about two square meters can exist in the true fire of the earth pole and can absorb the breath of flames, doesn't that mean that the strange things in this small fire island are not afraid of this magma flow.

"What's in there?" Xu Jianxing touched his chin and said, if you want to let him leave like this, Xu Jianxing must be unwilling, after all, how can he be willing to give up this thing that is about to be in hand, the most important thing is that if he gets what is here, it is not a way to leave here. At least in a sense, he didn't have to be so taboo about this extreme true fire. (To be continued......)
