In the underground karst cave, there is a winding and rugged underground crack, which is more than ten miles long, about one mile wide, and nearly 100 zhang deep. Underneath the great fissure in the ground is a slow-flowing fiery magma with a dazzling red glow.

The earth fire continued to gush out from the big crack, and the earth fire even rushed to a height of dozens of feet, and there were many hot bubbles in the magma river. The entire magma river was red and red, and the red light soared into the sky, turning the entire karst cave into blood red. By the magma river, the scorching heat is pressing, and even ordinary low-level fire-type demon beasts can't withstand such a strong force, and rarely haunt near the magma river.

At this time, a figure in green clothes and a girl in a blue shirt were standing on the edge of this big crack. It was Ye Qin and the girl in the veil, they carefully avoided the demon beasts along the way, and killed more than a dozen third-order demon beasts in a row, so they finally came to this magma river. Nearly a hundred feet deep beneath their feet is a breathtaking magma river.

Ye Qin had already turned on the blue water system body shield to resist the scorching aura that was rushing towards his face. The scorching heat here is so strong that in order to maintain the amulet, it is necessary to constantly and slowly consume mana to support it.

The veiled girl stopped at the edge of the big crack and looked at the magma river below, feeling the need to explain to Ye Qin, lest he be confused.

She pursed her red lips lightly, and said in a delicate voice, "This big crack is the deepest part of the Ten Thousand Dry Mountains. Thousands of years ago, the earth fire in this magma river erupted violently, terrifying all the demon beasts in this underground cave, and as a result, they fled in panic from the collapse of the second floor of the cave, and frantically rushed into the spirit stone mine, causing countless casualties to the miners of the major immortal cultivation sects. After the earthfire subsided, these demon beasts returned here one after another. ”

Ye Qinqi said: "How did Senior Sister Huangfu know?"

The veiled girl chuckled and said, "Thousands of years ago, the ancestors of various sects noticed that there was a fire gushing here, and they came to investigate, and they once entered this karst cave together, and took away a large number of tens of thousands of years of fire mineral crystals by this magma river. Including one of the patriarchs of the Qingdanmen, he also came here, and left some trivial information for the juniors of the sect, briefly mentioning the situation here.

The reason why the spirit stone veins of Wankuling were sealed was not only because of the open and secret battles of various sects, but also because the underground magma river here was unstable and could erupt at any time, so they were forced to give up the spirit stone veins of Wankuling, and the ancestors of each faction personally sealed the Wankuling cave. Otherwise, even if the major immortal cultivation sects killed and injured more miners, they would not leave here even if they were afraid.

There are many underground magma rivers like this in the Lingwu Mountain Range. There will be igneous ore crystals for hundreds, even thousands, or tens of thousands of years near the magma river. However, once the fire crystal of the Magma River is discovered, it will be quickly picked up by high-level immortal cultivators. In the underground of the Qingdan Mountain Range, there is also a tiny earth fire, and every five hundred years, fire-based crystals will be collected to quench fire-based magic weapons. ”

The veiled girl paused for a moment and continued: "After hundreds of years of eruption of earth-fire magma here, it subsided, and the major immortal cultivation sects gradually forgot about this place, and no one mentioned that they wanted to reopen Wankuling Mountain, so this place was completely abandoned. Now it seems that the ground fire in this Ten Thousand Dry Mountains is just a small-scale eruption, and it is not too much of an obstacle, and it only needs to completely wipe out the demon beasts in this underground to avoid injuring the miners. ”

Ye Qin couldn't help but say: "This Ten Thousand Dry Mountains have been sealed for thousands of years, and this must have accumulated a lot of thousands of years of fire mineral crystals. After the monks of various factions enter this cave and clean up all the demon beasts here, they will definitely mine fire ores here on a large scale. ”

The veiled girl said, "Yes, we must take away a small part of the fire mineral crystals here as soon as possible." Otherwise, when the monks of various factions come, there will be a lot of trouble. ”

Ye Qin nodded silently.

Senior Sister Huangfu's words suddenly solved many doubts in his heart.

He looked down at the magma river, and the most precious fire ore crystal, just below the rock wall of this big crack, was scorched by the earth fire for thousands of years, and was quenched from the most ordinary fire ore into an incomparably precious ore crystal.

He said quietly: "This rock wall is nearly a hundred zhang long, how deep do you have to go down to find this fire type ore crystal?"

"On the verge of an eruption of earthfire"

The veiled girl hesitated and said, she didn't know much about it. The Jindan ancestor of Qingdanmen thousands of years ago only mentioned that there was a fire mineral crystal in the underground magma river here, but did not say where the ore crystal was.

She stood on the edge of the Great Crack, looking at the rock walls on both sides of the Great Crack Magma River, and after a while, she saw the red shining crystals on the rock wall one by one, and her face suddenly showed a look of surprise, and said, "Senior Brother Ye, the Fire Mineral Crystal is just below, about ten zhang high from the magma river. ”

Ye Qin narrowed his eyes and looked over carefully, on the large crack rock wall shrouded in the dazzling red light of the magma river, there were indeed some faintly shiny red ore crystals.

But after seeing it clearly.

Instead, he gasped.

The earth fire in this magma river was violent, erupting from time to time and spewing out a stream of hot magma, splashing more than ten zhang high.

Even if the protective shield is opened, it will at most support a small moment in this fire.

But in this short period of time, it is impossible to dig out the fire ore crystal. Even the spirit stones on the second floor of the cave are difficult to dig. Not to mention the fire ore crystals on the side of the three-layer magma river in this cave.

If it is sprayed by this ground fire, it is equivalent to being hit by a mid-level fireball that is greatly enhanced, which will greatly consume the mana of the amulet. Once the mana in the body is exhausted, it is death. It is not easy to get your hands on the fire ore crystals there.

Ye Qin was shocked: "The river is ten zhang, and it is too close to the magma river. The earth fire can erupt to a height of ten feet, and it can be hit by the earth fire at any time. It's not too much of a problem to bear it, and you can't break the protective cover, but if you take a few more hits, no one can bear it!

The veiled girl shook her head cautiously and said, "You can't use a body shield to resist the earth fire." The ordinary Red Flame Earth Fire is about as good as the Yang Fire of a Qi Refining Stage cultivator. And among the thousand wisps of red flame earth fire, there is also a more domineering wisp of green flame earth fire, which is completely comparable to the power of the innate true fire of the foundation building period monks. And among the thousand wisps of blue flame earth fire, there is another wisp of blue flame, which is similar to the samadhi true fire of the Jindan monk. If it touches a wisp of blue flame earth, it is enough to break through the protective shield and be burned to ashes, and the original god will not be able to escape. Therefore, you must not use a protective shield, you must use a magic weapon to resist. ”

Speaking of this, the veiled girl seemed to smile, and said crisply: "Senior Brother Ye, I remember that the magic weapons on those ancient artifact disciples are gone, and they should all be taken by you, right? ”

The veiled girl was reluctant to use her own Ice Spirit Sword to dig hematite crystals on the rock wall, and if she damaged her Ice Spirit Sword, she would not be able to draw it. She smiled slyly and hit Ye Qin with her idea, she knew that Ye Qin had a lot of garbage magic weapons on his body.

Ye Qin was stunned for a moment, touched the storage bag for a long time, and was stared at by the blazing gaze of the veiled girl, and reluctantly took out a low-level flying sword magic weapon and a low-level Ruyi ring magic weapon. The disciples of the Ancient Artifact Sect left six or seven magic weapons, all of which were put away by him, and they were not used for a while, and they were all thrown in storage bags, but he didn't expect them to come in handy now.

The veiled girl took the two small magic weapons, her pretty face was indifferent, but she smiled quite proudly in her heart. Senior Brother Ye Qin is really well-behaved, this flying sword can be used to mine ore, once the earth fire erupts, it can rely on another Ruyi ring to resist, it is just right.

"Let's go, come with Senior Sister!"

She walked miles along the edge of the Great Fissure in the ground, finding a place where the magma river was gentle and the fire was not erupting. After observing for a full hour, he found that there was nothing abnormal, and then he slowly climbed down the rock wall on the side of the large crack. It's so dangerous here that I don't dare to use the Wind Resisting Technique at all.

Ye Qin then cautiously stepped on the concave rocks on the rock wall, and gradually climbed down, but showed a bitter smile.

He couldn't help but think of the situation seven or eight years ago, when he was digging herbs in Zhuqi County, he also had to take great risks to collect herbs on the mountain peaks and cliffs. It's just that at that time, he was only a ten-year-old apprentice of herb picking, except for his stamina, he had no strengths, and when he encountered a wild wolf in the suburbs and mountains, he could only desperately flee for his life. If he hadn't accidentally stepped into the immortal path, I was afraid that he would still be in Zhuqi County at the moment, running among the mountains for the herbs one by one.

Now he is a ninth-level monk in the Qi refining period, and he doesn't know how many times better than seven or eight years of money. But in the entire immortal cultivation world, he is still the lowest level of cultivators, and he has almost no status. If you die in this cave trial, you won't even be able to make a wave.

Ye Qin thought as he grabbed the rock and climbed down slowly.

He was surprised to find that there were many cracks in the rock wall, and the large ones could even hold several people. It is estimated that when the large cracks in the ground cracked, these small cracks also cracked and formed.

I climbed down about seventy or eighty zhang, and there were about twenty zhang or so from the magma river. The scorching heat here can't even be stopped by the protective shield, making the skin faintly painful. On the rock wall at this height, there are already a lot of pale red and red igneous ore crystals.

Ye Qin glanced down, and Senior Sister Huangfu was still climbing down. He gritted his teeth, took the gourd on his waist, and took a small sip of frost fruit wine, and suddenly his whole body was extremely cold, not only recovering his mana, but also dissipating the heat all over his body.

They continued to climb down until they were only ten feet away from the extremely threatening Earthfire Magma River, and the two of them stopped climbing any further.

The location here is the best, and when the fire erupts, it burns right here. The fire-based ore here has been quenched by the earth's fire for thousands of years, and has been extremely pure.

Fortunately, the magma river surface of this section of the river they selected seems to be calm now, and there is no earth fire spewing out. They can calmly dig up the fire ore crystals here. If you go further down, close to the surface of the lava river, it is too dangerous. Upward, the fire of the earth fire is not enough, and the ore crystals are not pure enough.

The fire ore here is already light purple or even dark purple. The darker the color, the older the crystal.

Ye Qin was pleasantly surprised to see that on the dark and hot rock wall nearby, there were small pieces of purple crystals, most of which were light purple, but one was dark purple. He suddenly glanced at the purple knife used for mining in his hand in confusion, and the purple knife in his hand was very pale purple. "This purple ore crystal, with purple purple like a purple knife, is it quenched from this purple ore crystal?"

The veiled girl glanced at it, but said with a smile: "Your purple knife is only oozing a small amount of amethyst, where is it the same." The amethyst here is formed after repeated refining of the blue flame fire. If the whole amethyst is used to refine the magic weapon, then the power is afraid that the Jindan monk will not be able to hurt it in the slightest. ”
