The deep cave was bottomless, spiraling downward, the little leopard, Jin Nanqing, and the rest of the Wu family disciples followed closely behind Zhao Ting, walking towards the bottom of the cave.

At the front of the line was the King Snake, and beside him, there were four masters of the Bone Forging Realm, two of these four were from the Mingyi Academy, and the other two were masters of the Heavenly Dragon Dao.

Zhao Ting followed closely behind them, followed by Little Leopard and the others.

The king snake's expression was a little unpleasant, and so was the little leopard, holding the hammer handles with both hands, and his face was serious, as if he was a little nervous.

And Jin Nanqing and the others, while looking nervous, were more excited.

Underground fire veins!

In this Zhonghe county, there is an underground fire vein.

This can't help but make Jin Nanqing not excited, the underground fire vein refers to the place where the fire surname Yuan power is the most abundant in this world, for those who practice the fire line internal qi, it is simply comparable to the legendary cave heaven blessed land, because practicing in the fire vein and honing the internal qi can almost omit the most tedious step of cultivation.

The first step of cultivation is to incorporate the Yuan Qi in the Heaven and Earth into the body, and then use the internal power to decompose these Yuan Qi, absorbing only the Yuan Power of the Fire Xing in it, and expiting out the rest of the Yuan Power of the caste, which is Tuna.

And in the fire vein, there is no need to consider this step at all, because in the underground fire vein, all the yuan power is the fire force, you only need to directly incorporate these yuan forces into the body, in this way, the efficiency of cultivation will be greatly improved, and one day of cultivation here can even be compared to a month of cultivation in the outside world, or even several months.

If you don't consider the factor of physical strength, practicing the Fire Movement Technique here can raise the internal qi to the sixth rank in the shortest possible time.

Because of this, the little leopard's face looked a little unhappy, if he had known, he wouldn't have listened to the words of that guy from the king snake, and let his Wai Dan also practice the Nine Dragons Divine Fire Skill, in this way, in this underground fire vein, wouldn't his Wai Dan cultivation have risen and flown away?

It's a pity that there is no regret medicine in this world.

Besides, this king snake didn't force you to cultivate, just gave you a suggestion, you cultivated after the people left, so even if it's weird, you can't blame it on the head of the king snake, and the little leopard can only consider himself unlucky.

Of course, this is just a function of the underground fire vein, a very inconspicuous function.

After all, there are countless exercises in this world, and the Five Elements Exercises are just one of the countless internal qi exercises, and the Fire Movement Exercise is only one of the Five Elements Exercises, although there are a lot of cultivations, but there will definitely not be too much, not to mention, this underground fire vein is not something that any cat or dog can use, like the little leopard who practiced before the fire heart method, ran to this underground fire vein, and it is estimated that within a few days of cultivation, he will be supported by the powerful fire force and die.

The biggest benefit of the underground fire vein is for the Wu family.

The smelting family of the Wu family creates all kinds of blades, and the more divine weapons, the less impurities there are, and if you want the impurities of the blade to become less, the most important thing is the temperature, even if you have a smelting family like the Wu family, the control of the fire temperature is also limited, at most, when refining some real divine weapons, in order to reduce impurities, the spirit stone of the fire line is used in the furnace to increase the temperature of the furnace.

Not to mention that the spirit stone of the fire surname is extremely precious, but even if the spirit stone is really used, the temperature of the furnace water will not increase too much, all along, a smelting family like the Wu family has been studying how to increase the furnace temperature, and the ancestor of the Wu family was able to lay the foundation of the Wu family, in addition to his own efforts and strength, the most important thing is that he has mastered a fuel that can greatly increase the furnace temperature, and it is this fuel that has taken advantage of other smelting families at the beginning of the Wu family's business.

But five hundred years have passed, and the Wu family has also experienced several periods of troughs and tribulations, and this fuel production method that originally belonged to the Wu family has also leaked out, which is no longer unique to the Wu family.

Although it is not popular, all smelting shops of some sizes have used the Wu family's unique fuel as early as fifty years ago, which has raised the smelting level of the entire Dajin Dynasty to a whole level, but for the Wu family, this is not a good thing.

Their biggest competitive advantage is gone.

Fortunately, they still have the Nine Dragons Divine Fire Skill.

This internal qi gong method from Tianlong Dao is not something that anyone dares to touch, and no one will be stupid enough to fight the idea of this exercise, and it is obvious that this exercise is also miraculous for removing impurities in the metal, so the Wu family has survived the most difficult years after its establishment.

These are all off-topic.

The topic is that the fire element power in this underground fire vein is extremely strong, and it even goes straight to the underground rock flow, if a smelting workshop can be built here, then the forged blades are at least three grades higher than those forged in other places, and even, if the operation is good, it can even produce sub-divine weapons in batches here.

Yes, sub-divine soldiers!

The divine soldier is a kind of thing that can be encountered but not sought, and it is impossible to forge a divine soldier without chance and real strange things and materials.

But the sub-divine soldiers are different, they do not have the magical effect of the divine soldiers, but in terms of sharpness and toughness, they are also second only to the divine soldiers.

The most important thing is that the sub-divine soldier is not as difficult to produce as the divine soldier, as long as there are good materials and smelting conditions, the top craftsmen can make it.

Just like Xu Yong, the master of the little leopard, he is a top-level forger, if he builds a furnace in the fire vein of the center of the earth and gives him some high-grade materials, he can quickly create a sub-divine weapon.

Therefore, if the underground fire vein is obtained by the Wu family, then the overall strength of the Wu family will inevitably reach a new level, and the Wu family with the fire vein can even become the real number one forging family in the world.

Of course, this is just an illusion, Jin Nanqing is not a fool, and the Great Jin Dynasty is not a fool, how can such a place be given to the Wu family?

The underground fire vein has another benefit, that is, it will produce spirit stones belonging to the fire element.

The leylines can't be taken away, but the spirit stone can, although the spirit stone is known as the most peculiar thing, but the strange thing is a strange thing, no matter how many there are, it is impossible to sell it like Chinese cabbage, and the closer the place with the largest number is to the underground rock flow, that kind of place, how can ordinary people go?

The strength of people who can really get close to the underground rock flow is at least above the seventh grade, and they have been refined into a gang qi amulet, but the strength has reached such a point, the attraction of the spirit stone to them is small, and besides, the strength of the strong person who has reached the seventh grade, will you be a miner?

This is impossible, so even if there are more spirit stones in this leyline, it is an unattainable treasure.

However, in addition to the place near the underground rock flow, in this fire vein, other places may also contain fire caste spirit stones, but the number of such spirit stones can be imagined, and if you want to get it, you have to rely on your own luck.

Fire Vitality, Earth Fire, and Spirit Stone These are the three most attractive benefits of the fire vein.

In addition to these three major benefits, the underground fire vein also has other benefits, but these benefits are relatively niche and the audience is relatively small.

The Wu family is also among this very small audience.

That is, generally speaking, in the fire veins that contain the underground rock flow, there will also be the earth's vein evil qi, which is fatal to ordinary people and even martial arts masters, but it is an incomparably precious blessed land for those who have cultivated to the sixth rank of the fire practice method, because they can condense these evil qi into gang qi.

Condensation!

The Wu family, as a smelting family, will appear in each generation of seven-rank powerhouses, therefore, they also have some places for the condensation of the leyline evil qi for the elders in the family to use for refining Gang, but these earth vein evil qi either exist for too long, use too many people, or the number is not enough, the success rate of condensing is not high, and even the evil qi is mixed and impure, and there will be danger in the process of refining.

Therefore, in recent years, some elders of the Wu family, even if they have cultivated to the seventh grade, rarely condense and refine Gang, just for fear that something will happen, and the same is true for Lu Yueyue, he is a seventh-grade cultivator, but unfortunately, he has not condensed Gang Qi, so when facing other strong people, he always feels that he will be a head shorter.

And the associated leyline evil qi in the underground fire veins is countless times that of the Wu family in terms of quality and quantity, if Lu Yueyue can condense it here, I believe that there is a seventy percent certainty that it can succeed.

This is what Kim Nam-hyun is most happy about, and at the same time, he is the most concerned thing.

This time, they left Yunzhou just to track down the whereabouts of a batch of goods, which was just a very small thing for the huge Wu family, but they didn't expect that they would encounter so many uncoordinated things, and finally found an underground fire vein in this inconspicuous Zhonghe County.

This underground fire vein is in the county town of Zhonghe, it must belong to the Great Jin Dynasty, and other families can't touch it, and as the court of the Great Jin Dynasty, in order to effectively use this fire vein, it will inevitably take into account the influence and technology of the major smelting families of the Great Jin Dynasty, you know, even in the Ministry of Industry of the Great Jin Dynasty, those craftsmen, most of them are from the major smelting families, and the real technology is in the hands of the major families, not the imperial court, although the imperial court will send people to the major families every once in a while to learn skills, but the major families are not fools, and will pass on the real skills to these people, because, want to effectively use this fire vein, indispensable for the participation of major families.

And how to participate, how to distribute the benefits, this will inevitably lead to a fight, whether he Jin Nanqing, or the little leopard, in front of these giants, they are just little ants that can be trampled to death, the only difference is that now, these little ants of the Wu family have taken the lead.

If they can take this opportunity to seek a little advantage for the Wu family, this credit will be great, not to mention anything else, if they can win a place for Lu Yueyue to condense here, then, at least until Lu Yueyue dies, they can all go sideways in the Wu family.

Of course, this is just a beautiful fantasy of his, a little ant of their status can't turn the tables, at most they just fight for some advantages that other families can't get for the Wu family.

Even this little advantage can be endlessly beneficial for them in the future.

So, Kim Nam-cheong was excited.
