The volcano is about 100 feet high, and there is no grass growing on the entire mountain, and the traces of magma flowing through it are still vivid, but judging from these stones, this volcano has not erupted for decades.

Yi Xuan stood on the crater and looked down.

Hundreds of meters below, the magma was constantly bubbling and bubbling, and waves of heat continued to hit Yi Xuan.

Yi Xuan used the Mixed Yuan Sword Technique in his body, and sent streams of hot qi out of his body. Yi Xuan had not yet reached the level of a Xuan Master, and he was unable to form a layer of Xuan Force shield outside his body to isolate the invasion of the heat wave.

"The ignorant crystal mine that Shi Lie said is here. Yi Xuan looked at it.

Just above the magma, there are large and small caves. These caves are naturally formed, and at Yi Xuan's location, some of the caves can faintly reflect a trace of red light. Yi Xuan knew that those should be fire crystals.

"The fire crystal is a high-grade spiritual object at the human level, although Shi Lie said that this fire crystal mine is only seven or eight miles, and it is only a low-grade ore vein, but it is enough for Zixiao to advance. Yi Xuan thought secretly.

"However, Zixiao's advancement is to directly devour all the fire crystals. All the fire crystals are gone, which will inevitably cause the mountain to collapse. The movement of the mountain collapse is too loud and may indirectly trigger a volcanic eruption. Yi Xuan then thought.

"At that time, I may face the danger of being crushed by boulders and magma entering my body. It's okay for the boulder to be pressed on the top, with my current physical strength, even if hundreds of catties of boulders hit me from a height of tens of meters, it will at most make me suffer a little skin trauma. ”

"But this magma entering the body is different, the temperature in this magma is afraid that it has reached thousands of degrees, even if I enter the body of the human level equivalent to a high-grade mystical weapon now, it will not take a moment and a half, there will be a wisp of gray smoke!"

Rumble!

As if in response to Yi Xuan's words, a boulder fell into the magma, gurgling, and in half a breath, the boulder was swallowed up.

Yi Xuan's face was solemn, due to the high temperature test for many years, although the stones on this volcano had not evolved into spiritual objects, the hardness of each stone was no less than that of ordinary human-level mid-grade mysteries.

Even such a stone was completely dissolved in just half a breath, and it was conceivable that even if Yi Xuan's physical body was stronger than this stone, it would definitely not be able to support it for long.

"It would be nice if my physical body could reach the level of the best human level, although this physical body level still can't resist the high temperature erosion of magma, but it can support enough time for me to escape from this volcano. Yi Xuan's face was slightly regretful.

Yi Xuan's physical body has already reached the level of the upper grade of the human level, and it is only one step away from the level of the best grade of the human level.

"But now I can't take care of it so much, there are less than twenty days left in the Xuanling Secret Realm, and in such a short period of time, I'm afraid it will be difficult for me to find a third vein. You have to take a risk!" a hint of determination flashed across Yi Xuan's face.

"What's more, if I'm faster, it's not necessarily impossible to escape from this volcano before the magma destroys my body!"

Yi Xuan looked at the large and small mines on the volcanic wall, trying to find a mine cave that could be entered. Some of these caverns have no contact with any other places, as if a hole had suddenly been smashed into a flat surface. If you want to enter through such a mine, unless you have cultivated to reach a high-level mystic, you can fly.

However, due to the impact of several volcanic eruptions, the volcano Bishan has been washed out of protrusions similar to roads. Some of these roads are wide, some are narrow, some are flat, some are uneven, some are coherent, some are broken. And the outside of some of the mines is connected to such a road.

Yi Xuan found the widest and smoothest path from beginning to end. The cave connected by this road is about 100 meters away from the crater, not far or close. If the road continues, Yi Xuan can cross it in two breaths.

If the road is broken, then Yi Xuan can only ask for more blessings.

Although the road is wide, it is only compared to the number of roads here. In fact, the widest part of this road is only half a meter, and the narrowest one even reaches twenty centimeters.

Yi Xuan didn't choose to use eight steps to chase the wind all at once, but walked slowly step by step. He wanted to see if there were any dangling or unsturdy places on this road, these places were nothing to step on when he walked down, and with Yi Xuan's current eight-step realm of chasing the wind, it was impossible to fall, at most it would take a little time.

But if you step on it when you come back, it will be miserable, and this little time wasted may kill you!

When it comes to his own surname, Yi Xuan has to be cautious. Not to mention, when Yi Xuan walked, he really found a few places that were suspended as soon as he stepped on them. These places are very secret, and if Yi Xuan hadn't stepped on them personally, his soul would not have been able to perceive them.

Soul perception can only reflect the structure of the object, and as for what the structure is, soul perception cannot know. Legend has it that when the soul perception reaches a high level, it can even automatically analyze all the components of the object and what kind of attacks it can withstand.

Although Yi Xuan's soul perception was already comparable to that of a dual Xuan Master, it was still far from this realm.

Yi Xuan firmly remembered these positions, and secretly told himself that he must not step on them when he comes back!

The further down, the higher the temperature. By the time I got to the front of the mine, the temperature had reached hundreds of degrees. At this temperature, I am afraid that it will not take long for ordinary people to be roasted.

Fortunately, Yi Xuan is a Xuanshi and can use Xuangong to resist. Although it will consume some Xuan power, it is not a problem for Yi Xuan, who has the five major dantians. As soon as the five major dantians are operated, the consumed Xuan power can be recovered immediately.

The cave is not big or small, about two meters high, and the width is barely enough for two people to pass through.

Yi Xuan slowly walked into the cave and unfolded his soul perception at the same time. As soon as he released his soul perception, Yi Xuan felt that his soul perception had been affected. Yi Xuan exerted all his strength, and found that the soul perception that could have shrouded nearly three miles could now only envelop more than one mile. Nearly half of the shrunk!

"Could it be that there is any naturally generated formation here that suppresses the soul?" Yi Xuan thought. In Yi Xuan's memory, only the formation could suppress the soul perception.

But soon, Yi Xuan denied his idea.

"No way, I can't feel a trace of the formation here. Even if it is a natural formation, as long as it is formed, there will definitely be traces of the formation. Although I haven't studied much about the formation, I rely on the soul perception of the dual Xuanshi, unless this formation is of a very high level, and it is the legendary heaven-level formation. Otherwise, it would never be impossible for me not to see a trace. ”

Yi Xuan is still very confident in this point. As for saying that there is a sky-high formation here, it is even more impossible. The Heavenly Rank Formation is so precious, and it is also the existence of the Mountain Guarding Array among the five major sects. Yi Xuan didn't believe that such a formation existed in a volcano he found at random.

"There is no formation, why is that, why is my soul perception suppressed here?" Yi Xuan thought as he lowered his head. Thinking about it, Yi Xuan's soul perception couldn't help but extend downward, and he wanted to find out.

But the further down he went, the more suppressed Yi Xuan found that his soul perception was suppressed, and even when he reached the surface of the magma, Yi Xuan found that his soul perception could no longer enter. If you force yourself in, you will even hurt your own soul.

"Temperature will suppress soul perception?" Yi Xuan was surprised.

Seeing this phenomenon, Yi Xuan thought about it for a while, and naturally came to the result. However, Yi Xuan was still a little surprised by this result. The soul cannot feel it, but the temperature can be felt. Temperature can suppress soul perception and even hurt souls, which made Yi Xuan a little surprised.

"But it makes sense when you think about it. The soul can be a type of energy, and temperature can also be a type of energy. It turns out that it is all energy, and nature can also affect each other. I don't usually feel the effects of it, it's just that I've been at a similar temperature. ”

"Isn't there a rumor in ancient times that there were powerful evil mystics who even forcibly detained and destroyed people's souls with their own mystical powers?

However, from this incident, Yi Xuan also found that his knowledge was a little thin and incomplete, and there should be records in these sects, but he hadn't even seen it.

"When you go back, you must read through these materials. Yi Xuan thought secretly in his heart.
