Whether it is formation, casting, or alchemy, it is the same path as the path of cultivation, and the division of each major realm level is clear.

In terms of the way of alchemy, in addition to reaching the level of Xuan-level first-grade alchemy master in terms of alchemy, his own cultivation must also reach the realm of a great war master before he can refine a Xuan-level first-grade elixir, which is common sense, but it is not impossible to break.

Just as a cultivator of a lower realm can cross the realm and kill a cultivator of a higher realm, if an alchemist's cultivation is not enough, he can use other means to refine a higher level of pills.

Among them, alchemy is the most important factor, just like the cheats are for cultivators.

A low-level cultivator who cultivates high-level exercises can defeat a high-level cultivator who cultivates low-level exercises, in other words, an alchemist who has mastered high-level alchemy, even if his own true qi cultivation is insufficient and his soul power is barely enough, he can refine high-level pills.

Li Xuan is such a special case.

In terms of cultivation, he used to be a top powerhouse, controlling his own strength to a terrifying degree, integrating his multiple powers, owning the Nebula Dantian, and comprehending countless cheats.

In the way of alchemy, he used to be a heaven-level nine-rank alchemist, these experiences and memories are priceless, and what he has mastered is the ancient alchemy left by the Great Freedom Demon, and the soul power is even stronger to a terrifying point, and he can completely cross the limit of common sense, and refine the Xuan-level six-grade elixir with the cultivation of the Great War Master.

But there is no limit to such a thing as leapfrogging, a cultivator of the Great War Master realm may be able to compete with the War Spirit, but no matter how powerful it is, it is absolutely impossible to compete with a strong person at the Battle Sect level, because the gap between them is too big and beyond the limit.

Therefore, with Li Xuan's current ability, he was actually unable to refine 100% of the Xuan-level six-grade elixir.

As for the so-called mysterious master behind him, it is just a fictitious thing.

However, if he could obtain a kind of Heaven and Earth Alien Fire, with the alchemy he had mastered, he would be able to refine the Xuan-level Six-Rank Soul Immortal Pill with great confidence!

After all, in the past, he had mastered the existence of several different fires, but unfortunately now Ziyanyan and Liuliyan were lying in the system space and could not be used.

The help of the alien fire for alchemy and refining weapons is simply an extremely terrifying increase.

There is still some time before the closure of the Spirit Martial Realm, and the next opening will not be until fifty years later, and only those under the age of thirty will be allowed to enter.

One person, there is only one chance to enter the Lingwu Secret Realm once in his life, Li Xuan naturally does not want to miss such an opportunity, and wants to make use of his limited time to find more resources and treasures.

More than two months have passed, and most of the more than one hundred and twenty Great War Master cultivators who have entered the secret realm have lost most of them, and among them, those who died at the hands of Li Xuan alone, there are more than a dozen people in the Star Palace and the Qin family's royal family combined.

In addition to some of them being killed by other cultivators, there were also many people who broke into the treacherous place in the process of searching for the treasure of chance.

Those places where the aura of heaven and earth is rich are more likely to give birth to treasures, and there will also be more dangers, such as the prohibition of ancient formations, or powerful demon beasts, blood souls, and there is no shortage of existences comparable to the battle spirit level.

In an open plain, Li Xuan saw several disciples of the Golden Spirit Palace, among them was a young man named Huang Xuanhong, who had won him over on behalf of the Golden Spirit Palace.

At this time, Huang Xuanhong and several people had some injuries on their bodies, as if they had just experienced a fight.

"Brother Li is also going to Lingwu Cave Mansion?"

Seeing Li Xuan, Huang Xuanhong asked.

"Lingwu Cave Mansion?"

Li Xuan muttered with a puzzled look on his face.

Glancing at Xu Mengxi and Ruo Shuirou beside them, the two of them also shook their heads to indicate that they didn't know.

Seeing Li Xuan's expression, Huang Xuanhong knew that he didn't know about the existence of the Lingwu Cave Mansion.

"Lingwu Cave Mansion is not a big secret, your Qin family royal family of Lingwu Country, as well as our Golden Spirit Palace, as well as Xingchen Palace and Meteor Palace, all know the existence of this Ancient Cave Mansion. ”

After Huang Xuanhong pondered for a moment, he explained slightly, it looked like he had a good relationship with Li Xuan.

Although Xu Mengxi was a member of the Qin family's royal family before, she was not told about Guan Lingwu Cave Mansion in her identity, and Ruo Shuirou did not hear Chen Yaojun and others mention it.

Obviously, this Ancient Cave Mansion, if not a big secret, is definitely the core secret of the four major forces. This made Li Xuan look at Huang Xuanhong with some doubts, why did the other party tell him about such a confidential matter?

Seeing Li Xuan's puzzled and inquiring eyes, Huang Xuanhong smiled and said, "Even if I don't tell Brother Li, as long as you continue to move forward, you can still see the location of the Ancient Cave Mansion, so there is no such thing as a secret or not." ”

"Since there is an Ancient Cave Mansion, why don't you go in? ”

Li Xuan's eyes flickered a little, and he asked slowly.

"There was a formation in front of the door of the cave, and we couldn't pass through it, and only a very few people entered. ”

Huang Xuanhong shook his head slightly, and said with some pity.

"Oh, what's in the cave?"

Li Xuan asked again.

Since someone has entered, Li Xuan believes that he should be able to enter as well, after all, among these people who have entered the secret realm, in terms of strength, no one can compare to himself.

He was more concerned about what treasures were in the cave.

Regarding this question, Huang Xuanhong shook his head and said: "I only know about the Lingwu Cave Mansion, and the other things are not very clear, I heard a senior brother in the palace who came here fifty years ago said that someone had found a first-grade soldier in it. ”

"Oh!?A soldier of the first rank of the prefecture?"

Li Xuan couldn't help but be a little surprised.

In the Lingwu Realm, only a few powerhouses at the peak level of the Battle Sect have ground-level soldiers.

After a while, Li Xuan took Xu Mengxi and Ruo Shui Rou to the location of the so-called Ancient Lingwu Cave Mansion.

According to Huang Xuanhong, the Lingwu Secret Realm is a place for the disciples of the Lingwu Sect to experience in ancient times, and all kinds of treasures, treacherous places, blood souls, demon beasts, and caves placed in it are all to sharpen the disciples.

The cave mansion was located in a valley with open space, and there was a formation light curtain flickering at the entrance of a stone cave, and more than a dozen cultivators gathered nearby.

Of the cultivators who are still alive today, except for a few people who are scattered in other places and who have entered the cave mansion, there are only these people left.

The masters of the younger generation of various forces can be described as suffering heavy damage this time, Li Xuan estimated that when the time came, there would be no more than thirty people alive among the more than one hundred and twenty people.

Here, Li Xuan once again sensed the majestic and vast aura of heaven and earth, just like the aura that erupted later in the area where a large number of colorless stones appeared.

The breath of the dragon vein!?

Li Xuan looked at his feet, obviously this Ancient Cave Mansion was on top of the dragon vein.

The entire secret realm is a super-large formation arranged on the basis of the dragon vein, and the level of the formation surpasses the ground level, even the powerhouses of the Zhanzun realm cannot break in with their strength.

Moreover, this dragon vein has existed for endless years, and the terrifying power it contains makes people feel terrible even when they think about it.

Li Xuan took a deep breath, although the dragon vein made people feel terrifying, but the so-called wealth and danger were sought, this ancient cave mansion, he had to break through everything.

From time to time, there were more than a dozen cultivators in front of the stone cave who stepped forward to try to see if they could enter, but as soon as they walked over, they would not be able to move an inch, and they retreated back one by one with pale faces.

"Is it a soul attack? Their souls seem to have been impacted, and their soul power is extremely consumed. ”

Ruo Shuirou whispered beside Li Xuan.

Li Xuan nodded, the formation in front of this stone cave did have the effect of soul attack, even in ancient times, the formation that could attack soul was extremely rare and rare.

"I'll try. ”

The voice fell, Li Xuan walked over, and there happened to be two people trying to pass through the formation light curtain together.

These two people were disciples of the Meteor Palace, and they both had high-level cultivation of the Great War Master, and as soon as they walked in front of the formation light curtain, they couldn't continue to move forward, and they retreated back with a pale face.

At this moment, Li Xuan walked forward, and a mysterious aura rushed towards him, hitting the depths of his soul.

This mysterious aura that impacts the soul is probably equivalent to the soul attack of a Xuan-level soul refiner, and it can generally be resisted as long as it has the soul power strength of a Xuan-level alchemist.

Shaking his head slightly, Li Xuan continued to walk forward, and when he walked to the front of the formation light curtain, the impact of the mysterious aura on the soul went from the low level of the Xuan level to the level of the middle level of the Xuan level.

This level of soul attack was naturally nothing to Li Xuan, who used to be a heaven-level alchemist, but if he didn't have the corresponding soul power strength or cultivation to reach the high level of the Great War Master, he would definitely not be able to support it.

Obviously, the people who had entered this Ancient Cave Mansion before should all be high-level cultivators of the Great War Division.

Even if you don't have the ninth-level cultivation of the Great War Master, you must at least have the soul power of the Xuan-level low-level.

Among the dozen or so people present, almost all knew Li Xuan, this was a guy with enough strength to kill the ninth level of the Great War Division in seconds, and no one showed an expression of surprise when he was able to smoothly walk to the front of the formation light curtain, and his face did not change.

Just when everyone thought that Li Xuan was about to enter the stone cave through the light curtain, they saw him suddenly turn around and walk back.

"Mengxi, come here. ”

Standing still, Li Xuan suddenly shouted with a smile to Xu Mengxi, who was not far away.

Xu Mengxi's cultivation is only the peak of the sixth level of the Great War Division, and she is not a special profession, the strength of her soul power is definitely not enough, if it were herself, she would not be able to enter this ancient cave mansion.
