From the mouths of the two elders of Jinhuo before, Duan Tian also had some understanding of the Huogang Cave, and now the two elders have gone to sleep and recuperate.

In the depths of the Lianyun Mountain Range, there are many caves that run through it, and these caves are born with Huogang, which is a kind of evil qi, which can also be called Gangfeng, which is of great benefit to monsters and humans.

The most pure Yuntian Huogang Cave in the core area of the Lianyun Mountain Range, the grade is Tianpin Huogang, which is occupied by the Huoyun Roaring Yun family, and its strength is huge, and its strength exceeds any of the ten major factions in Chuzhou, even the Qingyun Sword Sect is probably not an opponent.

Tianpin Yuntian Huogang Cave is surrounded by hundreds of thousands of miles, full of earth products and human character Huogang, and it is also where the demon clan forces affiliated to the Huoyun Roaring Yun family are located.

When the Heavenly Machine Divine Sect was at its most powerful, it was unable to completely occupy this place, and these Huogang were born by attaching to the leylines of the Lianyun Mountain Range, and they could not be transferred at all, unless they moved the Lianyun Mountain Range for millions of miles.

Even with the strength of the Divine Machine Heavenly Sect back then, it was impossible to do it at all, and he could only take away some Gangfeng, and with the passage of time, these Gangfeng would slowly dissipate.

In addition to the Lianyun Mountain Range, there are naturally Gangfeng in the vast mountain range and the Flame Basin, but the highest quality is the ground product, which is far less pure than the Huogang in the Yuntian Huogang Cave.

Gangfeng is of great benefit to the cultivation of the fire-attribute demon beast human race, not only can it cultivate spiritual power, strengthen the body, but also cleanse the soul.

For the human race and demon beasts, all kinds of Gangfeng are extremely rare things, and they can be used directly.

Outside of the Nine Heavens, there were also a wider range of various types of Gangfeng, but only Yuanying monks could reach them, and ordinary monks could not fly to such a high place at all.

Although the effect of Gangfeng is excellent, but the general human race and demon beasts are also unbearable, the foundation building period can use the character Gangfeng, the Jindan period can use the earth Gangfeng, only the Yuan infant level can use the Tianpin Gangfeng.

Through Tie Er, Duan Tian also knew that there were some character Huo Gang distributed in the vast mountain range, and after the foundation was built, he could go to find Huo Gang to cultivate, Duan Tian was a golden fire attribute, and both gold and fire Ergang could be used.

The Gangfeng Tunnel is also pregnant with natural Gangsha, and these Gangsha are also quite different in combat power according to the different quality of Gangfeng and the length of time it has been formed.

The Heavenly Fire Gang Cave will give birth to a fire gang spirit with spiritual intelligence, and its combat power is like that of a primordial infant.

The Evil Spirits equivalent to the Jindan Period were bred in the Ground Gangfeng Cave, and the Evil Spirits equivalent to the Foundation Building Period were bred in the Character Gangfeng Cave, and these Evil Spirits will never be destroyed, but will only be dispersed.

Later, it will be slowly reborn in the Gangfeng Cave, growing with the growth of Gangfeng, and dissipating with the dissipation of Gangfeng, and many monks and demon beasts are buried in the hands of evil spirits.

However, in the long process of cultivation, the Terran monks also found a lot of ways to collect and use Gangfeng, and many monks went to find Gangfeng Cave and collect Gangfeng for sale, of course, the price was extremely expensive.

In particular, the Evil Spirit is used in more places, and the price is also extremely high, and the higher the level, the more expensive the Demon Spirit.

More than a month later, in a high mountain in the middle of the vast mountain range, Duan Tian was looking for the Gangfeng Tunnel.

There are also countless natural caves in the vast mountain range, some of which stretch for tens of thousands of miles, crisscrossing countless branches, and if you are not familiar with the road, you will not be able to walk out at all.

The interior of this cave in Duan Tianlai stretches for thousands of miles, and there are countless large and small caves, many of which have no wind, and they need to be found slowly.

Here Tie Er had been here with Song Hongyi back then, and he was also familiar with this, and under the guidance of Tie Er, Duan Tian slowly looked for Gangfeng.

The generation of Gangfeng is also irregular, especially the character Gangfeng, which is not as durable as the earthly and heavenly Gangfeng.

Some will dissipate over hundreds or even decades, while others will persist for thousands of years, and many caves will spawn at any time.

What Duan Tian was looking for was the land of Gangfeng that had hundreds of years, and the evil spirits produced by this land of Gangfeng had the strength of the late stage of foundation building, and the Gangfeng was relatively stable, which had an excellent effect on cultivation.

In the land of Gangfeng that is less than a hundred years old, the Gangfeng grade is not good enough, and the evil spirits produced are not powerful enough.

The more powerful the evil spirit is recovered by the human race, the better the effect, and it can be used to refine the alchemy array method to feed the spirit beast, and the greater the value.

On the one hand, Duan Tian went to borrow Gangfeng to cultivate, and on the other hand, he also wanted to recover some evil spirits in order to earn Xuanshi.

Of course, it is more important to charge as much gangfeng as possible. After Duan Tian communicated with Elder Jinhuo, he knew that the foundation of creation could also collect Gangfeng.

If the cave is opened up to accommodate it, the capacity of the Gangfeng absorbed is far greater than that of the ordinary magic weapon that collects the Gangfeng, although it cannot be stored permanently, but the storage time is greatly enhanced, and the speed of the Gangfeng dissipation will be much weaker.

Duan Tian has been asking Duan Sanfat and the other three beasts to open a cave in the foundation mountain of creation in order to store Gangfeng.

With these winds, it will also be of some help to the restoration of the foundation of creation.

After continuing to search for more than a month in the vertical and horizontal cave, Duan Tian finally found a Gangfeng Cave, and as Duan Tian went deeper, the Gangfeng became stronger and stronger, it was Huogang.

Clusters of red mist-like things emitted a dry heat, and as the wind became stronger, the temperature became higher and higher.

This cave is winding and turning, and there are many branch caves, and it is impossible to find out whether there are demon beasts infested, and Duan Tian can't help but be careless and sneak in slowly.

This fire gang is like a dense fog, it can't see the distance at all, and it also has a great impact on the divine sense, and it can only be detected for more than ten miles here, and it is blown away by the fire gang.

Even if there were other cultivators or demon beasts cultivating with the help of Huogang ten miles away, Duan Tian would not be able to detect it.

Carefully laid down the small Jiugong Bagua Array, Duan Tian asked Tie Er to manipulate the array, and he began to cultivate with the help of Huogang.

This small Nine Palace Bagua Array was adapted by Yi Qingchen from Wei Ning's Nine Palace Bagua Array that day, it was a three-level formation, Duan Tian studied the formation in general, and he didn't use it much on weekdays, so he passed this array to Tie Er.

Tie Er is also a little proficient in the formation, Song Hongyi's two formations have been destroyed, and this formation is just right for him.

Duan Tian ran the Flame True Gold Technique, carefully absorbed Huo Gang into his body, and began to cultivate.

These Huo Gang are much more stimulating than the fire spiritual power in the air, and the spiritual power is peaceful, while Huo Gang is irritable, and when it enters the body, it is like a wild horse that has escaped from the reins, and it is out of control.

In addition, the temperature of the Huogang is extremely high, the stimulated Duan Tian's meridians are boiling hot, and the muscles and bones are also tormented, Duan Tian runs a hundred refining and purifying the heart, calms down, carefully controls the Huogang in his body, slowly concentrates the scattered Huogang, and constantly impacts the meridian bones.

At the same time, the soul is also wandering in the fire gang, feeling the stimulation of the fire gang to the soul in order to improve the strength of the soul.

Qi Yun Leopard and Black Jin naturally seized this opportunity to absorb the Gang Qi well, both beasts have fire attributes, and this Fire Gang is also very beneficial to them.

Duan Sanpang did not have a fire attribute, and the environment here was extremely unsuitable for him, so he naturally hid in the foundation of creation.

Tie Er had borrowed Huogang many times before, and now the effect of Huogang was not very obvious, so he concentrated on protecting and patrolling.

After more than a month of cultivation, Duan Tian had completely adapted to the Huo Gang here, so he continued to dig deeper to find the place where the Gang Wind was stronger.

After such a gradual strengthening of January and January, after March, Duan Tian has penetrated into the central area of this Character Gangfeng Tunnel, which is also the place where the Gangfeng is the strongest.

The temperature of these Huogang is even higher, if it weren't for the other Huogang baptisms that Duan Tian had experienced before, I am afraid that he would really not be able to bear it for a while. The effect of this thickest fire is definitely the best, and it is of great benefit to Duan Tian's cultivation.

After cultivating for a few days, Duan Tian heard Tie Er's voice: "Childe, some evil spirits have appeared in front of you, and they are slowly floating over. ”

As soon as he heard this, Duan Tian immediately collected his skills, and came in to practice for several months, but he had not yet discovered the evil spirit, and he just happened to see it this time.
