There are some naturally occurring passages in the cave, although not as many as in the gold concentrate, but most of the ignecite is connected.

As Yi Xuan walked, he used his soul perception to probe the content and approximate location of this fire crystal ore in order to find the most suitable devouring location.

In Yi Xuan's perception, large and small crystals with fiery red light were mixed within these stone walls, and only a few were exposed. Needless to say, these crystals that shimmer with a fiery red light are naturally fire crystals.

Yi Xuan walked for a while and saw a piece of exposed fire crystal, only a small part of this fire crystal was exposed, and the whole body was like glass, flashing with a fiery red light. Yi Xuan was a little curious when he saw it, and wanted to get this piece of fire crystal down to take a look.

Yi Xuan pulled it out vigorously and found that the fire crystal did not move at all.

Yi Xuan was surprised: "How is it possible? With my current strength, even a giant elephant can be easily lifted by me, and this small piece of fire crystal can't move at all?"

Yi Xuan, who did not believe in evil, increased his strength and pulled it out, but the fire crystal still did not move. In the end, it was Yi Xuan who used Sancheng Xuanli to knock open the stone wall next to this fire crystal, and only then did he get this fire crystal out.

This fire crystal is eight-sided diamond-shaped, palm long, three fingers wide, two fingers thick, and the whole body exudes a fiery red light. Yi Xuan held it in his hand, and he also felt a trace of heat in his hand.

Seeing this fire crystal, Yi Xuan couldn't help but breathe a sigh of relief.

"Fortunately, I don't need to dig these fire crystals by myself, I only need Zixiao Shi to expand the devouring realm, and I can devour all of these fire crystals. Otherwise, with the hardness of these stone walls, I may not be able to dig out all these fire crystals after digging for a year!"

Yi Xuan knew very well what the concept of his Sancheng Xuan Force was. Ordinary ninefold peak Xuanshi may not be able to withstand the blow of his own three-percent Xuanzi. And this small fire spar needs to be taken out by himself with thirty percent of his power.

And this is only exposed, you can imagine how difficult it is to mine these igneous crystals. I'm afraid that it will take Master Xuan to be a miner to dig this fire crystal mine.

However, what kind of identity is Master Xuan, he is at the elder level in the five major sects, how can he become a miner.

"However, this pyrotechnic ore should be considered relatively special among many ore veins, and ordinary ore veins may be attacked by high temperatures at all times. Just like the gold concentrate I encountered, the average three or four mystics can be mined. Yi Xuan swept the fire crystal in his hand and said lightly.

It took more than half an hour for Yi Xuan to finally check the entire Fire Crystal Mine.

Generally speaking, the veins will be inhabited by demonic beasts. Because the mineral veins will make the aura of a certain surname in it extremely rich, it will be of great benefit for the demonic beast to cultivate in it.

For example, gold concentrate, the metal surname aura in it is extremely rich. The Iron Armor Beast is a metal surname Demonic Beast, and it cultivates in the gold concentrate, and its speed is at least twice that of the outside world!

The same is true in the fire crystal mine, and the aura of the fire surname contained in it is far richer than that of the outside world. It stands to reason that there should be a fire-surnamed demonic beast stationed, but the place where the fire crystal mine is located is in a volcano.

In addition to the fire caste, the magma in the volcano also has a very special corrosive caste. In addition to magma demonic beasts and fire spirits, other fire-surnamed demonic beasts will inevitably be eroded by this corrosive caste when they enter this volcano to cultivate, and no fire-surnamed demonic beast wants to come here.

This is not to say that it is not good to cultivate in this volcano, on the contrary, if there is a Fire Surname Demon Beast that can persist in cultivating in the volcano, its own strength will grow even more rapidly. Because although the corrosive caste in the magma will erode its body, as long as it has been resisting it with spiritual power, it will have an excellent purification effect on the spiritual power in its body.

The corrosive caste in the magma will corrode the inferior spiritual power, thus raising the purity of the spiritual power to another level. Shi Lie did just that, although Shi Lie had just broken through to the Ninefold Xuanshi, his Xuanli level was no less than that of the ordinary Ninefold Peak Xuanshi. This is the result of his years of persistent cultivation in the volcano.

However, cultivating in the volcano is really too hard, not to mention the extremely high temperature, and you have to use your occult power to resist the erosion of the corrosive genus in the magma, and you have to maintain a high level of concentration at all times. This kind of life is something that ordinary fire monsters can't hold onto.

Shi Lie can persist for several years, which shows how strong his willpower is!

This is also the reason why Yi Xuan values Shi Lie. In Yi Xuan's opinion, in the cultivation of the Xuan Dao, the importance of willpower is no less than one's own talent.

In the midst of the volcano, Shi Lie's cultivation relied on willpower. And magma demonic beasts and fire spirits can cultivate in the volcano, but they rely on talent. They are not naturally afraid of the corrosive caste in magma, and even this corrosive caste can give them a boost in strength.

However, these two kinds of demonic beasts are very rare, and Yi Xuan has only seen them in the "Catalogue of Warcraft", and he has never heard of them appearing there in Mu Yunguo. Although the Xuanling Secret Realm was peculiar, Yi Xuan guessed that there were probably no such two kinds of demonic beasts here.

After all, both of these types of Demonic Beasts are simply too rare.

After reading it, Yi Xuan really didn't find the figures of these two kinds of demonic beasts. However, at this time, his face was a little unpleasant.

"It's not in a circle, it's in a half-moon shape. And its thickness is also uneven, starting from the apex on both sides of the half-moon, the thickness gradually increases, and when it reaches the lowest point, there is already a part of pyrotechite and magma connected together!" Yi Xuan's brows furrowed tightly.

"Zixiao's devouring realm has a limited range, with Zixiao as the center, it can only form an oval domain ten miles wide and one mile high. Once beyond this realm, Zixiao will not be able to devour the fire crystal. I have to go to the center of this pyrolite mine to ensure that Zixiao's devouring can successfully reach its goal. ”

"However, judging from the distribution of this pyrolite mine, as long as Zixiao devours it, it will definitely cause a volcanic eruption, and I, who am inside, I'm afraid it will be difficult to escape!" Yi Xuan's eyes almost crinkled into a Sichuan character.

After a long time, Yi Xuan suddenly gritted his teeth and said, "No matter what, no matter what, I have to try it! Not to mention that I am still wearing a human-level supreme defensive weapon, it may not be hopeless!"

Xuandao cultivation is to use one's own life to win the future.

For this, Yi Xuan saw it very clearly. Therefore, he will not retreat because of a little difficulty, not to mention that he will not be able to win enough resources, even in the depths of his heart, it will leave a shadow that will never be erased!

This is something that Yi Xuan will never allow!

Even if it's not for Zixiao Sword, just for himself, Yi Xuan has to fight it!

Yi Xuan spent nearly half an hour checking the entire Fire Crystal Mine again. One passage after another crossed in Yi Xuan's mind, and gradually, several of the fastest and shortest paths were selected by Yi Xuan.

Yi Xuan deliberately chose a few more roads to prevent the mine from collapsing.

After choosing the road, Yi Xuan came to the center of the fire crystal mine, a small cave of thirty or forty square meters. Yi Xuan didn't immediately start to let the Zixiao Sword devour, but found a place to sit down and breathe.

Half an hour later, Yi Xuan stood up. Whether it is the Xuan Force, the soul or the mentality in his body, he has reached the best level.

"Everything is ready, it's time to go!" Yi Xuan's eyes flashed with a gleam.

Yi Xuan pulled out the Zixiao Sword and plunged it into the ground.
