Dark iron can be said to be the most common and common refining equipment in the cultivation realm, but it does not mean that it is overflowing, just like gold and silver in the mortal world, it is also a precious thing.

And according to the year of formation, different dark iron in the quality and value, there are worlds of difference, generally a hundred years for the entry level, where iron at least through the erosion of heaven and earth vitality for a hundred years, its internal structure to change, can be regarded as a dark iron, generally a hundred years of dark iron hardness is more than four or five times that of steel, and spirituality is strong, and the divine consciousness is easy to form communication and resonance, so it is a common thing to refine all kinds of magic weapons, in front of this piece of dark iron vein and regardless of its year, only with such a large scale, it is an extremely considerable wealth, not to mention from the scene of divine consciousness to open, the quality and year of this piece of dark iron vein may be high bizarre。

The aura of steel emanating from this vein is like the abyssal sea, vast and endless, the divine consciousness is reflected, and the soul is like the oppression of the mountains, and there is a sense of darkness.

Moreover, among these steel mountains, there are many fossilized bones, the shape and outline of which are not today's creatures, quite ancient.

"The breath of this dark iron vein is vicissitudes and ancient, and it contains the bones and fossils of the primeval beasts, I am afraid that the age is quite old, and it is close to the dragon vein of Puyang City, which is eroded by the vitality of heaven and earth, and the quality is also extremely high, and it can be directly refined into a magic weapon without quenching. Zhang Qian's heart was secretly astonished, extremely surprised, and suddenly remembered that Shen Gu was the city god here, and this dark iron vein was right under his nose, and the scale was so huge, he didn't know anything about it, so he asked: "What is the scale of this dark iron vein? It seems that it has existed here for a long time, and such a heavy treasure, how can no one take it." ”

Shen Gu remembered when he mentioned it, and said: " This dark iron vein has indeed existed for a long time, at least I had it when I was a city god, but it is not here, but in the lava layer in the center of the earth, more than 5,000 zhang away from the ground, there are very few people who can detect it, only the earth immortal Yuan Shen of the Yuan Shen realm can be found when he comes out of the body, and the master of the earth immortal is a person who does not know how to measure, although this black iron vein is a huge wealth, but how difficult it is to take it out of the lava layer in the center of the earth, even if there is such a means, making such a big disturbance will make the entire Puyang City become a sea of fire, such a sin, who is willing to bear it？”

"Before, in the lava layer in the center of the earth, no wonder this is the case, the primordial gods and earth immortals are all people who are close to the birth and destruction of the thunder tribulation, and they pay great attention to merit, how can they increase the variables when they cross the tribulation because of things outside their bodies. Zhang Qian nodded secretly.

"And Emperor Dongyue also knew about this, and he issued an edict at the beginning, who dared to covet this thing and bring natural disasters to the human world, and he would not spare it, so few people dared to fight the idea of this thing. Shen Gu continued.

There was one point, Zhang Qian's heart was already extremely incomprehensible, listening to what he said, it became more and more strange, although this dark iron vein is infinitely valuable, but for Emperor Dongyue, the lord of the human world, it is nothing, as for Puyang City, it is only a remote town in Shuzhou, and it is not so important, but it is an edict to give instructions, which is obviously a bit excessive, frowning and asking: "How big is this vein?"

"It's about ten miles in diameter. Shen Gu replied.

Zhang Qian was slightly surprised when he heard this, although the scale of ten miles was not small, but it did not exceed his estimated value, he was surprised by Shen Gu's words, mentioning the word diameter, which means that this vein is a spherical shape? Zhang Qian once stayed in the Qinghe Mine Cave in Xiaowei Mountain for a period of time, and naturally knew what the distribution of the veins looked like, most of them were in the shape of pages, long strips, or sporadic distribution, although the natural creation was a miraculous workmanship, it was impossible to form a round and regular shape, and I didn't know if this Shen Gu used the wrong words, so he asked: " You said earlier that this vein of dark iron ore is ten miles in diameter, is it still a symmetrical circle?"

Shen Gu shook his head, his expression was also a little strange, and said, "This dark iron vein is spherical, like a chicken egg. ”

"Spherical! How can the vein be of this shape?" Zhang Qian was even more surprised this time, if the vein is round, it may be a coincidence, forming a spherical shape, how small is the probability of this, hundreds of millions of stubborn stones in the world, it is impossible to find a pure round stone, let alone the vein? What is even more incredible is that such a big thing, obviously in the lava layer 5,000 zhang deep underground, suddenly floated up 4,000 zhang, and happened to block his way! muttered to himself, unable to figure it out for a while:" This vein is bigger than a mountain, like a star, who has the ability to lift it from the lava layer deep in the center of the earth! Shen Gu, do you know who did this?"

Shen Gu shook his head when he heard this, and said: "At the end of the war, I had run out of oil and lost consciousness, and I didn't know what happened later, I think this dark iron vein was also affected by the aftermath of the great array and changed its position at that time. ”

Listening to what he said, Zhang Qian was able to accept it, after all, the dragon vein stone pillars were all broken and sank by three thousand zhang, and it was indeed reasonable for this vein to be displaced.

"What should we do now, is it to bypass this vein?" Shen Gu asked.

Zhang Qian's eyes closed slightly, looked at the pitch-black iron curtain in front of him, shook his head, and said: "Break it, the heavens will not take it, but take the blame, now that Puyang City has been destroyed, it will also cause something that is not afraid of natural disasters." ”

"That being said, how can such a large vein of dark iron ore be obtained?" the corners of Shen Gu's mouth twitched, as if he had a toothache.

He was born in a businessman, extremely profitable, and he was unwilling to give up such a large sum of infinite wealth in front of him, but he was self-aware and his ability was limited, so he had no way to take this vein.

"Take as much as you can, and when you enter the treasure mountain, you can't go home empty-handed. Zhang Qian said indifferently, as if this infinite wealth in front of him was just dispensable, and then his divine sense reflected the boundless iron curtain under him, and the door of the Linglong ** Tower quietly opened, and the dazzling sun true fire turned into a "Zifeng Chishu Spirit Mantra" The fish came out and landed on the pitch-black iron curtain, although this dark iron vein is extremely huge, and even the most superficial year is more than three or four hundred years old, and the ordinary flame is not calcined at all, but in front of Zhang Qian's perverted means, it is like snow water, easily melting, and then turning into hot gold juice, flowing into the world in the tower along the portal.

Zhang Qian did not take all the orders, first calcined them fiercely with the true fire of the sun to remove impurities, and some of the dark iron that was insufficient in the year was directly turned into vapor volatilization.

What remains is at least close to the quality of a thousand years, and washed with a god of heaven, leaving only a part of the sinking water, suspended above the water surface of the direct exclusion, this day a god water density is very large, a drop weighs more than 10,000 catties, although it is divided into a lake, the density is much smaller, but some years are insufficient, It is still very difficult for low-quality dark iron to sink into the water, after such screening, the years of the dark iron that finally sank to the bottom of the water are at least more than 1,200 years, and they are perfectly eroded by the vitality of heaven and earth, and the flawless kind only accounts for about one or two percent of the total, and the rest are all abandoned, and Zhang Qian is helpless.

This piece of dark iron ore vein is extremely huge, even if he has Lingling Liuhe Tower, but the world in the tower is only about ten miles in radius, and the sky dome is not opened, it is very low, not as long as the four poles, it can't accommodate it at all, so he has to give up.

Just because he gave up these dark irons, the quality of the vintage was not low, and after some calcination and quenching, it was also a sought-after thing when placed in Xiuzhen Street.

However, there is an inexhaustible supply of dark iron in front of him, and the deeper he goes, the higher the quality, the longer the vintage, he doesn't feel much pity, and later, the proportion left by the screening is getting higher and higher, and when he dives into the depths of a hundred zhang, the dark iron in the Linglong ** tower has been piled up into a ten-zhang high hill, I am afraid that there are tens of millions of pounds, and there is such a heavy burden, and the urging of the Linglong ** tower is also more and more difficult, and now he is underground, unable to grab the true fire of the sun, Zhang Qian also has to support Linglong with his own true qi The operation of the tower, with the power of only one person, may be difficult to support alone, and in the end, Ji Du and Luo Hu also provide assistance, injecting their own pure yang vitality into the Linglong ** tower.

The two of them are favored by it every day, and now they also have a heart of return, although this pure yang true qi can be described as a drop in the bucket, but it is also a heart, and it is better than nothing.

When it went down to the depth of 500 zhang, the quality and age of the surrounding dark iron had reached an incredible level, which was nearly 10,000 years old, and there was the vitality of heaven and earth overflowing from it.

Ten thousand years of dark iron, the spirituality is vast, and it can be used to refine ancient spiritual treasures!

Now melted into the tower these dark iron gold juice years are seven thousand years old, just cut a piece, no need to spend a lot of effort, as long as it is polished into the shape of a flying sword, it can be classified as a high-level spirit treasure, you can imagine how high the quality of these dark iron is, but it is a pity that the more Zhang Qian swept away, the burden on his body became heavier, and the higher the quality of the surrounding dark iron veins, the more difficult it was to smelt, it was simply difficult to move an inch, Zhang Qian had no choice but to learn from the monkey to break the bag, and discard a large part of the dark iron that had been hard to screen before, and try his best to scavenge these higher quality dark iron that has been nearly 10,000 years old, and at the same time continue to sneak into the depths to seek greater benefits, all the way down, like an earthworm, in the hard soil layer to drill a deep tunnel.

"This is only halfway through, if you go to the bottom, wouldn't the year of Xuantie be as high as tens of thousands!" Zhang Qian secretly thought in his heart, quite excited, tens of thousands of years of Xuantie can only be described by the words "can not be found".

If he can get it, it will be a huge windfall for him, even if he is calm, he will be shaken by it.

However, Lingling Liuhe Tower sank halfway, but it was suddenly blocked, and it was difficult to advance an inch.

Condensed into the "Purple Phoenix Red Book Spirit Mantra" The layer of dark iron in front of the calcination of the sun true fire was unresponsive, Zhang Qian was secretly surprised, the fire pill in his body rotated violently, the sun true fire gushed out like a stormy wave, the fire was strong to an incredible point in an instant, Bai Huanghuang sunlight radiated away, it was actually the previous melting of the Yongdao illuminated, like an extreme bright world, there was nothing else in the sight, as if everything was swallowed by the strong light, the high temperature swept away, Zhang Qian's previous burning out of this temporary mine road was actually invasive, the iron walls on all sides were like paraffin, rolling and melting, Zhang Qian did not waste, all into the bag。

These 9,000-year-old dark iron had begun to melt when the fire radiation was even directly burning, but the black barrier under him did not move at all.

Zhang Qian's brows furrowed, even if it was a 10,000-year-old black iron, it should have shown signs of melting like this, but now it was useless.

"When things are impermanent, there must be demons. Zhang Qian frowned slightly, extinguished the true fire of the sun, in addition to wasting his efforts like this, there was no point at all, and when he exhausted all his strength, I am afraid that he could only be trapped underground, and then put the breathless armor on his body, and raised his wings, like a long knife out of the sheath, through the portal, escaped out of the Linglong ** tower, and landed on the black barrier, in Linglong** In the tower, the consciousness is affected by the breath of steel, and the things in front of him are like seeing flowers in the fog, and there is no reason at all, but now with personal contact, he has found many clues, and the armor of no breath is extremely heavy, and when he lands, his feet are on the iron wall, making a really heavy and muffled sound.

The sound is extremely strange, like a heavy wood colliding, without the crispness and melodiousness of the intersection of gold and iron.

Zhang Qian was suddenly surprised, how could there be wood in this dark iron vein, even if it was involved by chance, it should have become a fossil now, it was definitely not this kind of sound, he squatted down, his fingertips lightly touched the black barrier under his feet, the tentacles were cold, and a sharp steel breath invaded from the fingertips, making the meridians faintly painful, and a layer of goosebumps appeared on the fingertips, it must be metal, and the breath was so strong, it was enough than the years he had scraped before** The thousand-year-old quality of Xuantie was even higher, and as soon as his mind moved, a wisp of pure yang true qi escaped from his fingertips, and suddenly the dark and lightless barrier under his feet suddenly surged with a burst of blue light.

A jade like jade in the sun!

"Ten Thousand Years Xuantie!" Zhang Qian's color changed suddenly, although he had already prepared for this, but when he suddenly saw it, he was still shocked in his heart.

Although the 9,000-year-old Xuantie and the 10,000-year-old Xuantie are almost the same in age, the quality is vastly different, just like a watershed in the cultivation realm.

The 10,000-year-old Xuantie already has spirituality, and when it encounters pure yang vitality, it is like a shark smelling blood, and there is a strong devouring **.

Therefore, the spirit treasure made of 10,000 years of dark iron, and the pure yang vitality of the high fit is incredible, the power is also extremely strong, the quality alone has been able to initially reach the standard of the ancient spirit treasure, look at the ghost light in front of you, it seems to spread from the depths of dozens of zhang, the glimmer is like water, flawless, obviously the quality is also extremely high, such a large piece of excellent quality of the ten thousand years of iron, if you are willing to continue to invest in the world, I don't know how many ancient spirit treasures can be refined, what a huge wealth? However, Zhang Qian did not move for this, since he was a 10,000-year-old Xuantie, he should not be able to resist the erosion of his 'Purple Phoenix Red Book Spirit Micro Mantra', fire energy can overcome gold, not to mention the true fire of the sun that gathers into a fire pill!

And the 10,000-year-old black iron knock shouldn't make such a sound.

Zhang Qian collected the pure yang true qi, gathered a wisp of fire at his fingertips, and gently pointed to the surface of the 10,000-year-old Xuantie, his eyes condensed, staring at it with all his attention, not daring to miss a trace of details, and at the moment when the fire touched the huge 10,000-year-old Xuantie, a layer of fine runes suddenly emerged, the handwriting strokes were like ant touches, and the color changed with the firelight, it was extremely difficult to be found in this dark and lightless underground, and it was also Zhang Qian's eyesight, only to find a clue, I am afraid that nothing could be found with the divine sense induction, because these talismans did not have a trace of breath, but they were like an unbreakable barrier, blocking all the fire, and it was impossible to burn the 10,000-year-old Xuantie below。

"It's incredible. Zhang Qian's eyes and brows were furrowed, and he was touched by the scene in front of him.

Shen Gu was able to accommodate himself in the Breathless Armor, and communicated with Zhang Qianxin, so naturally he also saw this scene, and he was already speechless.

"This ...... This...... What the hell is going on?"

He has been in the position of the city god of Puyang City for more than 200 years, although this dark iron vein was once buried deep in the underground lava layer, but with the dragon vein stone pillar, it can also be sensed remotely, only when it is the formation of heaven and earth, today Zhang Qian went deep into the core but found that there was a talisman blessing in it, that is, this thing is not naturally formed, but created by manpower, who has such a hand, gathered such a large-scale dark iron, especially the core of this 10,000-year-old dark iron, its value even if it is a big sect of the Sanqing Palace, but also give birth to a covetous heart, but this thing is not a spiritual treasure, what is the meaning of being stored hereCould it be the treasury of the great power of the heavenly immortals in ancient times?

"No wonder this dark iron vein is of such a strange shape, it turned out to be a gathering of manpower. Many of the questions in Zhang Qian's mind were gradually solved.

Suddenly thought of the edict issued by Emperor Dongyue, and also faintly guessed, could it be that this also knew about this, or that he had a friendship with the original owner of this batch of huge quantities and extremely high quality Xuantie, so he deliberately maintained it, and now he plundered it privately without his permission, will it make him angry, but then he shook his head and denied his own thoughts, now that Puyang City has been destroyed, these Xuantie will be exposed to everyone's sight sooner or later, and he will lose his care, even if he doesn't take it, others will take it and fall into his own hands, which is better than cheap outsiders。

Immediately, his gaze fell back on the huge piece of 10,000-year-old black iron, causing the fire to continue to burn, and the talisman reappeared.

Zhang Qian was prepared this time, but he saw it more clearly.

I found that these talismans were a little familiar, as if I had seen them somewhere, and after thinking about it carefully, I grabbed the clue in my memory, and I was shocked on the spot!

The words mixed in these talismans are very similar to the two talismans that Zhang Jiude sent him away and Su Muqing painted in the heart magic realm at that time, but the talisman covered with the 10,000-year-old Xuantie under his feet is more than 10,000 times more complicated, and it is even more huge, with so many words, like an ocean, even if Zhang Qian's soul is now strong and his mind is quick, at a glance, he also feels dizzy and embossed, let alone sort out his head.
