In order to test the hardness of the earth-stone, Xu Jianxing took a few steps forward and got another piece. After using the force of seven minutes, Xu Jianxing discovered that his pure power that could crush even the ninth grade ordinary materials at this moment, left a white mark on the earth-stone.

Looking at this situation, Xu Jianxing was overjoyed again. According to his estimate, the Earth-Central Stone had at least reached the level of a demigod-level material, and perhaps it was directly a god-level. Although the Great Sage of Qiankun brought him a lot of materials, Xu Jianxing still didn't want to move those materials, and not to mention that some things were free and what they obtained through himself were two concepts.

The most important point is that the mining profession will definitely be revealed here and 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, he still had more than 1,000 pieces. Even if one item can be supported for half a month, he could resist it for nearly fifty years, not to mention that he also had various magical pills and the fur of many Immortal Priest-stage monsters. The fur of these monsters, even if they are not made, are equivalent to the top-grade immortal weapon level. If you do it casually, even if you can't reach the semi-devil artifact, there will be no difference. In this case, Xu Jianxing believes that staying in this area for thousands of years is a small matter.

Of course, if Xu Jianxing is really allowed to stay here for thousands of years, he may have to go crazy. After all, this place is not a good place. Maybe one will die in an accident. After all, this place is not a stable area at first glance. There is a change at a certain point. It is not normal. And if he falls into the magma, things will be really unpredictable.

Below, Xu Jianxing began to explore this huge magma cave carefully. During the exploration, Xu Jianxing did not forget to collect ores, and perhaps carefully dug a few easy-to-digging ores. As he dug out one ore every time, the mining experience value would have a small jump.

At this time, a star element will also be born out of thin air in Xu Jianxing's dantian. Although these star elements cannot support Xu Jianxing's external consumption, it also relieves a lot.

Just explored this soon after.

Xu Jianxing found that there was no way to go in this direction, which made Xu Jianxing very painful. There might be places to go in other directions, but it would not be a problem to just wander around like this.

In fact, it’s not that there is really no way to go, but the road is just above the narrow stone wall flowing through. But Xu Jianxing can’t pass through the stone wall above, and if he does that, he will be really tired of living. After all, the stone wall is too hard, and seeing that the magma flow channel is only one person high, although he can suck the stone wall tightly after using the Star Yuan, he consumes a lot of money in the scorching heat of this terrifying road. If the road is very long, then in the end it is not a matter of seeking death.

As for the idea of ​​directly opening the hole and walking towards the top, Xu Jianxing didn't think much about it, because if he did that, if there was a magma flow in some place above, he would really have nowhere to escape. If the movement was a little bigger and he was directly submerged in it, it would be very normal. Therefore, Xu Jianxing dared not open the hole here randomly. Even if it was about to open it later, there was nothing we could do about it.

Then, Xu Jianxing didn't think much about it and changed direction. During the change, Xu Jianxing naturally would not forget to collect ores on the ground. However, Xu Jianxing only collected simpler ones, such as those that were really difficult to make, and Xu Jianxing was not moving. At this time, he still wanted to find a way to leave and said that if he could leave, it would not be difficult to come here in the future.

The reason why Xu Jianxing had this idea was naturally because somersault clouds were already there. Now, Xu Jianxing has discovered the biggest disadvantage of somersault clouds. This disadvantage is that it is easier for him to go in anywhere, but it becomes very difficult to get out. It is like a man deliberately dug a hole for him to jump, and after he jumps, he doesn't care. If he thinks about it, he can only find a rope by himself.

After a while, Xu Jianxing's eyes lit up, because he found a small stone island in the center of a magma stream. This small stone island only emitted red light under the magma, and its appearance was not good. However, Xu Jianxing knew very well that there must be another mystery here. Otherwise, in such a magma stream, how could a small stone island appear? Why does this small island seem to be absorbing the heat of the magma stream? If it is placed outside, not to mention this small stone island, even a million-foot-high gold and silver mountain will probably be melted in a moment.

After a little moved, a small flame that looked like a thin hair appeared from Xu Jianxing's hand, and then Xu Jianxing carefully threw it out. The main reason why Xu Jianxing did this was that considering different factors in the region, and according to his understanding, in some regions, a small spell with the same attribute would be infinitely enlarged, and this is also the kind of area that would be enlarged. The only different Xu Jianxing was to know how many times the spell would be enlarged and what kind of performance would be. If the performance was appropriate, he could use a little power to capture the small stone island.

However, there must be two prerequisite conditions here. First, it must be the true fire of the origin to achieve this condition. If there are other different fires of change, it can only make both of them unavoidable and explode. Of course, if your cultivation is high enough, this problem will not occur. Second, you must put your spiritual consciousness outside and hook the surrounding aura. There is still a great danger here. The danger is that if a person cannot control the spiritual consciousness well, it will make a certain attribute of the outside world more violent. Therefore, Xu Jianxing's movements are so careful.

Xu Jianxing threw a small flame outside, and at the same time, he forced the flame outside that could burn spiritual consciousness, and communicated slightly with the energy of heaven and earth. When Xu Jianxing used the energy of heaven and earth to communicate slightly with the small flame, the boundless fire element instantly crowded over, and suddenly turned the small flame into a big fireball. In an instant, it turned into a washbasin as big as a washbasin.

"Damn..." Seeing this, Xu Jianxing looked shocked. He knew how much mental power he had used, if he put this mental power outside, he could at most ignite a flame smaller than a match. He never thought that after coming here, he would be so terrifying, probably more than ten thousand times.

As Xu Jianxing's mind turned, the basin-sized fireball turned into the size of an ordinary round table. Then, in the notes of Xu Jianxing's eyes, the round-sized fireball trembled sharply, almost trembling for no reason. The huge fireball exploded with a loud bang.

Xu Jianxing was not very clear about how strong the explosion was. When the terrifying flame aura came towards him, Xu Jianxing hurriedly retreated. He instantly retreated to a place where there was nowhere to retreat. The explosion sparks sprayed everywhere, and suddenly a muffled sound of banging sounds. The only good thing was that the sparks did not cause much damage to the stone wall. Otherwise, Xu Jianxing himself didn't know what would happen, but even so, Xu Jianxing sensed that the flame slightly sprayed outside the artifact shield dimmed the light of the artifact's defense.

"Huh!" Xu Jianxing took a light breath and said, "Damn it, it's so scary."

Then, Xu Jianxing used metallicity, fire attributes, and other spells with various attributes to experiment here. Finally, he learned that no matter which spell is used, the ones that can play here are very small, so small that they do not use even a trace of heaven and earth energy. It is only his own star energy that plays a role, and the water attribute is the most. After all, the two have this mutual restraint. As for the wood attribute spell, it encourages some aura, but the aura that encourages is almost ignored here. Who made the earth-sensing true fire here powerful to an unknown level?

After the experiment was completed, Xu Jianxing began to conduct the next experiment. This experiment was to see how many fire elements were connected so that he could reach the point where his mind could go at will.

Don’t look at the simple experiment that Xu Jianxing did. But if the flame breath here does not reach a common rhythm, it is impossible to rely on the force. Just like although people in the real world are all humans, the fluctuations of the magnetic field are still completely different. The flame breath in the fairy world is naturally the same. Even if Xu Jianxing finally reaches the level of rhythmic balance, he can only use force to fight force, but he must not let the flame breath here hurt him. Unless the fire law that Xu Jianxing comprehended is higher than the flame strength here.

It took three days like this that Xu Jianxing had reached a subtle balance between his fire spell and the flame law aura here. In fact, if we talk about it, Xu Jianxing had another simpler way, which was to absorb the flame aura here for himself, and then slowly realized that although Xu Jianxing would suffer some pain here, he thought that there would always be a success day when the earth's true fire itself belonged to the original fire law.

But the problem here comes again. If he understands the true fire of the earth here, he will definitely ascend in the end. What Xu Jianxing doesn't want to do the most is ascend. After all, this not only involves the experience of adventurers, but also involves more unknown things. Moreover, if he doesn't pay attention to it, he will still attract a lot of fire. Who can tell that when he understands something, he must devote himself to it. If he is distracted from doing it, then there will be ghosts if nothing happens in an accident.

Not to mention, there are other unknown situations that will happen, such as the cave collapse caused by the hedge between the fire current and other places, such as the consumption of star elements, etc. So the best way is to escape and find a safe place to come.

However, even so, after finishing the balance of fire, Xu Jianxing carefully used the slight amount of Earth-Earth True Fire to practice for some time. After all, no matter what, this has many benefits for his safety, and it can also consume less Star Yuan. Moreover, Xu Jianxing was mentally prepared for a protracted battle.

The reason why Xu Jianxing was prepared was because he knew very well that the underground world of polar true fire must be like a huge maze, complicated, maybe after walking for a long time, it was possible to return to the origin. If you say that in that case, how could Xu Jianxing get out of it so simply? In Xu Jianxing's idea, the disaster he was going to survive this time was not the polar true fire. I am afraid that the main thing was the maze.

Of course, it is impossible to say that the polar true fire does not have any threat. After all, the instability of the underground world is almost something that people know. According to legend, there are still various strange creatures living in the underground world. As for whether it is, Xu Jianxing doesn't know.

In a blink of an eye, another ten days have passed.

After ten days, Xu Jianxing changed into a defensive artifact on his body. As for the one on his body, Xu Jianxing had entered the space. Although this artifact was damaged, the problem was not too big. I think it would be possible to recover after a few years with the nourishment of the spiritual energy in the space. To a certain extent, the artifact was exactly the same as a cultivator's injury.

When everything was ready, Xu Jianxing calmed down and carefully used the exercises. Suddenly, an invisible hand of flame appeared out of thin air. Immediately, the hand of flame grabbed the island in the magma stream.

As soon as he grabbed it, Xu Jianxing was stunned, because the endless flame energy was absorbed by Xiaoshidao, and nothing was left.

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