The area of the Lock Heart Fire Vein is actually very large, and the slack horn that really leads to the underground rock river is actually only one of the countless passages leading to the Earth Core Fire Vein, just because it is the largest, the longest, and the most spacious place to which it can be used to build a smelting room.

In addition to this most important wide passage. The walls of the passage are densely packed like beehives. Large and small passages can also lead to the underground rock river, but these passages are too narrow, or the place leading to them is too heavy and hot, so they are abandoned, or not taken seriously.

You must know that there are two most important functions of the fire vein in the center of the earth, one is that a smelting family like the Wu family can use the rock flow in the center of the earth to create sub-divine weapons in batches, and the other is that people who practice fire practice exercises like Little Leopard can condense and refine Gang. Boost your cultivation.

After all, there are very few forces in the world who are qualified to build a smelting room in this fire vein in the center of the earth, and now the Great Jin has only to go home, and they have been assigned to it, and although there are many people in the martial arts who need fire vitality to practice the fire practice method, there are very few people who are qualified to enter this fire vein. Even if you are qualified to enter this fire vein, if your strength is not enough, that is, if you can't reach the third grade, you will be poisoned by the fire poison in it.

And some people whose strength is truly more than the third grade, and who want to use this earth-centered fire vein to enhance their cultivation, are not qualified to enter this earth-centered fire vein. So there is a phenomenon of sneaking in like a leopard.

It's just that there are very few such people after all, and the Great Jin Dynasty and the four major smelting families are not so easy to deal with, in addition to the guards outside the door, there are also masters who go home in the main passages, so. Even if the guards outside the door are overturned, it is impossible to enter the depths of the main passage.

After all, there are already very few people who have cultivated to more than seven grades, and there are even fewer people who have cultivated more than seven grades of qi in the fire line, and these people are also the objects of the Great Jin Dynasty and the major forces, so there is no need to worry about not having the geocentric fire veins available, so it is enough to go home and arrange some masters in this main passage.

Originally with the status of the little leopard now. If you want to cultivate in this earth-centered fire vein, you only need to say hello to the Wu family, and the Wu family will naturally arrange everything, because now the leopard is not only the elder of the Wu family, but also the strongest combat power of the Wu family, no one doubts that his combat power has surpassed that of the Wu family's great elder Lu Yueyue, and he wants to retreat and improve his strength, which is also a matter of unwantable for the Wu family.

However, the leopard didn't think of this stubble at all, and he didn't have the heart to alarm the Wu family because of this matter, so he came directly. Unexpectedly, he actually ran into the rotation of the disciples of the Wu family.

Straight along the passage of the fire veins in the center of the earth. After walking for a while, the little leopard found a passage with the thickest fire vitality among the forked passages on the cave wall, and drilled into it.

There were very few passages, the height was up to his shoulders, and the width was about the same as his body. When the little leopard went in, it used a drill.

It was like a rat that got into this passage, and as soon as it entered the passage, a strong fire vitality rushed to the face with fire poison.

"It's so strong fire power, it seems that I have chosen the right place this time!" the little leopard said secretly in his heart. The Nine Dragons Divine Fire Skill of the Body Immortal was in operation, and he saw a faint fiery red flame swimming around his body, devouring the incomparably strong Fire Movement Yuan Power.

This is the second form of the Nine Dragons Divine Fire Skill, and in the world today, those who have cultivated the Nine Dragons Divine Skill to his point are afraid that there is no one else except for a few immortal elders of the Heavenly Dragon Dao

Finish.

For others, these fire poisons will kill them, but for the little leopard. The fire and energy around here are all great supplements.

The entrance to the passage was very narrow, and the leopard was ready to be a mouse, but after drilling for a while, the passage ahead gradually widened. Soon, he was able to walk straight through the passage.

After walking for a while, the surroundings became hotter and hotter, and the golden-red horses around the little leopard's body had increased to three, but he could still feel the bursts of heat.

"It's almost time to get to the location of the underground rock river under that sharp passage!"

The little leopard silently calculated his position.

This passage is very straight and very empty, and the speed of the little leopard is not slow, so after a little calculation, he found that he had gone deep into the ground at this time, and the little leopard frowned slightly when he looked at the passage in front of him, which still looked deep. "The rocky rivers under this earth are all connected. How is it that I still can't see a trace of the rock river until now?!"

This time, the main purpose of his coming to the center of the earth was to find the underground rock river, because he needed the earth fire essence of the abundance of the rock river to temper his muscles and bones, penetrate his fist intent, and condense his internal qi.

For others, the earth fire essence is an extremely rare thing, because they are hidden deep under the rock flow of the earth's core fire vein, ordinary martial arts masters, even the nine rank powerhouses, do not have the ability to go deep into the earth's core rock flow to collect this kind of fire vitality, and only by extreme chance, in some very special places, can they find this kind of superb fire vitality.

But the baby leopard does not have this problem. His Black Sun Fist intent has a seduction function, which can lure the Earth Fire Essence out of the Earth's Core Rock Flow. Therefore, he only needed to find a core rock flow, and then activate his Black Sun Fist Intent, how much did the Earth Tip Yuan Marrow want, and then use the Nine Dragons Divine Fire Skill to guide the Earth Fire Yuan Marrow into the body. Refining the body, refining the qi, refining the fist intent, this is his plan. But unexpectedly, after walking for half a day, he didn't find any trace of the underground rock river, which couldn't help but make him feel a little depressed.

"Damn, I think it was said in the book. These passages in the fire veins of the center of the earth eventually lead to underground rock flows!" So the little leopard also chose a channel where the fire line yuan power is the most prosperous, in his opinion, the fire line yuan power is the most prosperous, and the closer it is to the rock flow, otherwise, what is the fire burning so strong?

But unexpectedly, not only is it not the most recent. It may even be the farthest.

"That's not right, since the distance is so far, why is there such a strong Fire Element Force in this passage? I have now condensed five fire dragons, but if I don't reach the rock flow for another section, I'm afraid that the five fire dragons won't be able to hold so many Fire Element Force barbecues!"

The little leopard's cultivation is high, but he is also a human, and the fire power in this passage is getting stronger and stronger. made him a little unbearable, that is, he could still hold on for such a long time, if he was replaced by someone else, even if he was a seventh-grade powerhouse and cultivated to Gangqi, it would be enough for him to bear.

As soon as his mind moved, a faint layer of green light flashed around the leopard's body, and he carried the newly cultivated Qingyu Qianyuan Gang Qi, and the Biyou Sword also turned into a blue aura at this time, swimming around his fingertips, blocking all the boundless heat outside.

He came to practice, not to suffer, and the three golden red colors flying around him seemed to have absorbed the power of the fire line, and under the chaotic gathering, they were all flashing with golden red scales. The horns of the head, the dragon's whiskers, and the five claws became clearer and clearer, and they didn't look any different from the real existence, and they couldn't see that these three fire dragons were actually condensed by the inner qi of the little leopard.

The little leopard with a faint blue light around him descended for another two or three hours, and his expression changed suddenly, because, not far in front of him, the direction of the passage had changed, and he was standing here. He couldn't see the real situation after the passage turned a corner, but he could feel a huge amount of vitality enough to melt gold in the passage, gushing out at the mouth of the passage, and among these vitality, there was actually a large amount of earth fire essence mixed with it.

"No, this passage is the only one that leads to the bottom of the core rock flow. Only the earth fire marrow will exist in the place, my luck will not be so good?!" The little leopard muttered to himself in his heart, there is only one place where the natural earth fire marrow can exist, and that is the bottom of the core rock flow.

You must know that the depths of the center of the earth are mysterious and abnormal, and the wonderful places are no less than the bottom of the sea, like most of these core rock flows are directly connected to the center of the earth, but under this core rock flow, sometimes there will be some holes, these holes, just like those river tunnels in the previous life of the little leopard, the submarine passes, may pass people, but they are full of fearful fire poison, even a strong person of the first grade may not be able to survive in such a place.

So the little leopard stopped.

The blue light on his body was first sheng, and then, as if he thought of something, the blue light disappeared completely. As soon as he raised his hand, five golden-red fire dragons flew out of his fingertips and rushed directly to the hole at the bend, and at the same time, the little leopard's hand was raised again, and three golden flames flashed, and finally turned into a pillow composed entirely of flames, and also pounced towards the hole.

"Shhh After rushing straight over, the little leopard hissed violently, and he felt a steady stream of heat transmitted to his body through the fire dragon and the pillow, the Xuanhuo beating in the dantian, the Nine Dragons Divine Fire Skill, and the Bright Moon Transformation Divine Determination all ran violently at the first time, frantically absorbing the huge energy at the bottom.

I don't know how long it took, but the five fire dragons and Hui Zhu flew back from the entrance of the cave. Drilling into the body of the little leopard, a faint golden-red light emerged from the little leopard's skin, swimming.

The little leopard's eyes opened violently, and he took out a small white porcelain bottle from his arms, poured out three white pills from it, and put them into his mouth.

Yi Jin Dan!

This is Yi Jin Dan!

With the enhancement of the little leopard's strength and the improvement of his status in the Wu family, he has obtained a lot of resources from the Wu family, and An Yuantang has also relied on his strength to grow stronger and stronger, and now he not only monopolizes the shipping on the entire Luojiang River, but also starts a business of medicinal materials.

Although the medicinal materials of Yijin Dan are difficult to find, they are rare. But the little leopard didn't use these rare medicinal materials to make a decoction, he used it for alchemy, and he didn't need many medicinal materials, so although it was not easy, after he came back from the northern grassland, An Yuantang had already gathered the medicinal materials for alchemy, although the amount of several of the rarest medicinal materials was very large, but it was enough for him to refine a bottle of Yijin Dan.

After swallowing the three pills of Yijin Pill, the little leopard made a fortune to dissolve the medicinal power, and after the medicinal power was dissolved, the three strands of cold and piercing energy merged into one. began to swim between his muscles and bones, and the cold force was like a fierce ice thorn, piercing his meridians and bones, freezing his meridians and bones.

The baby leopard is now beneath the core rock. The boundless heat scattered around, but it still couldn't resist the fierce and boundless cold.

He stood up violently, his legs apart, and pulled out the frame, and the bones of his body clicked and clicked with his movements, sounding a little astringent, like the sound of stepping on the hard soles of his shoes in winter.

But after a while, the astringent sound of bones began to mellow.

"Click, click, click, when. Dang, ding, ding!"

In the change of voice, the movements of the little leopard were fast and slow, one moment was the Moon Demon Painting Skin Fist, the other was the Blood Demon Quenching Bone Fist, and finally, the Tai Chi Fist.

Slowly, his movements suddenly slowed down, looking at the speed, it seemed that he was playing Tai Chi with one move at a time, but in the middle of the action, it was mixed with the blood demon quenching bone fist and the moon demon painting skin fist.

The sound coming out of the bones of the baby leopard is getting clearer and clearer.

Ding, ding, ding, ding

It is like a pearl falling jade, a plate, crisp and pleasant.

Brush, brush, brush. Brush.

Suddenly, in the midst of this crisp and pleasant sound, there was a tidal wave.

Brush, to, brush

In the beginning, the sound was not loud, it was not very clear and incoherent, and as time went on, the speed of the little leopard's punches became slower and slower. The sound is also getting louder and more regular. It is as straight as the tide of the sea.

Whew, whew, whew. call

At this time, the little leopard seemed to be covered with mercury all over his body, and every movement had to drive the qi and blood in his body to churn. It evolved like a tide to the end, and it made a hula sound like waves in the sea.

At this time, the little leopard, the whole person has been immersed in a mysterious atmosphere, and the blood demon has a fist. Moon Demon draws a leather fist. There are also some other forging fists that the aliens in the thunder have concentrated into his brain, which are integrated in his mind, and they are no longer separated from each other, and what binds these fists together is Taijiquan.

Boom, concubine, boom,

I don't know how long it took, but a burst of thunder sounded from his body, and the slower the movement, the louder the thunder became.

"Whew, no, it's still a little close!"

The little leopard's movements suddenly accelerated, his arms stretched out violently, like an ape's arms, and his body rolled over as if uncontrollably in the air and fell to the ground. Under his feet, he seemed to be stumbling.

Straightening up, the little leopard's eyes narrowed slightly, and without thinking about it, he stepped straight towards the bend of the passage.

"There is still some heat left, although there are many earth fire primal marrows here, but they still can't meet my requirements. If I forcibly break through the Bone Forging Realm at this time, it will have an impact on my future development, and I need more and more refined Earth Fire Essence Essence. I need to go deeper into this passage!"

The little leopard thought to himself, and his feet did not relax at all. Directly into the bend of the passage.

"Whew!"

The violent heat rushed to his face, almost blowing the little leopard backwards, and the little leopard bit his teeth. There was a burst of golden-red light on his body, and he rushed in.

"This is the place!"

Finally, after the turn of the passage, the little leopard who passed through this extremely hot underground tunnel felt relieved.

He was extremely lucky, because the tunnel was not very long. After passing through this pass, the passage began to go upward, and the boundless heat weakened a lot, and the influence of the little leopard did not shake off the road!

The boiling lava was like slurry, emitting a huge amount of heat, and the golden red light illuminated the entire underground space very brightly.

This is a place where underground rock flows pass. There is also an underground cavity, but it is much smaller than the underground cavity that the main passage of the fire vein in the center of the earth leads to, but again, the heat is much stronger.

However, compared to the previous pass, which was mixed with a large amount of heat from the Earth Fire Elemental Marrow, the situation here was much better.

"It's here, it's finally here, and I'm just here "What is this?!"

The little leopard secretly rejoiced, preparing to use this place as his practice place, but suddenly, he was stunned.

Because he saw a strange thing, there was a rock in the middle of the rock flow in the heart of the earth.

The rock flow in the center of the earth is actually similar to the river on the ground, the difference is that the river flows water, and the rock flow is magma.

Therefore, in the process of the flow of the core of the earth, it will also be hindered, and the materials that make up the magma are different, and there are some special materials that may accumulate in the flow of the rock flow, just like the sand and gravel in the surface river, and over time, some small islands, stones and other things will be formed in the rock flow.

Generally speaking, on these islands, the stone does not exist for too long, because no matter how hard the substance. It can't withstand the erosion of rock flows day after day, year after year.

Now this rock flow in front of the little leopard is not wide. The golden-red magma flowed very smoothly, and the only anomaly was that there was a small island in the middle of the flow, or rather, the stone protruding from the flow was not an island at all, at most it was just a slightly larger stone, an obstacle.

To the surprise of the little leopard, it was this obstacle, on this black, very ordinary-looking stone, that the little leopard felt spirituality.

Strong spirituality, this stone is not a dead thing at all, judging by the feeling of a small leopard. It was a living creature, and such a strong spirituality was much stronger than the spirituality of the materials used in his green bead sword, and it was also stronger than the spirituality of his Shura Yin Evil Needle.

"The best material, this is the best material for refining magic weapons!" the little leopard screamed wildly in his heart, "If you wait for a few thousand more years, maybe this stone will be able to open up your spiritual wisdom, and maybe a monkey will come out of it." But now, it's just a stone, a piece of the best material for refining magic weapons!"

I don't know how many years this stone has existed in this core rock flow, how many strange substances in the rock flow have been accumulated, and it has gone through thousands of years of rock flow refining before it gave birth to such a strong spirituality.

When encountering such a baby leopard, he will naturally not be soft, nor will he let go, and raise his fingertips. The sword qi of the Anode Heavenly Sword shot out. Rushed straight into the rock flow, and cut it violently according to the place where the little leopard felt that the stone began to have spirituality.

"Sand!"

A strange sound sounded from the place where the sword qi of the Anode Tongtian Sword was cut, and then, the little leopard felt an extremely domineering force rebound from the root of the stone, and slammed into the Anode Tongtian Sword, and it was also a loss that the little leopard used the Anode Tongtian Sword, if it was replaced by something else. Whether it is a weapon or a martial art, it will definitely be blown away by this domineering and incomparable force.

"Not a stone!"

After this, the little leopard was finally determined. It is not the black stone that he sees in his eyes, but what lies in the stone.

The Anode Tongtian Sword was extremely sharp, although it received a strong counterattack, but it still stubbornly cut the root of the stone, and the dazzling golden-red light came out violently from the bottom of the rock flow, and the stone sank and disappeared into the rock flow.

There's no better place to hide than in a rock flow, when the roots of the stone have been cut off, and when it sinks into the rock flow, it goes with the flow like gravel in a river, and God knows where it will go.

Of course, the little leopard would not let such a thing happen, and when he saw the stone sinking to the bottom of the rock flow, he turned his palm into a knife, and the part of the rock flow that emitted a golden red light in the rock flow was everything.

The Art of Dividing the Two Realms!

In an instant, that space was cut open. Coming out of the surrounding space, naturally, the stone is nowhere to be found.

After the two spaces were separated, the little leopard's sleeve waved violently, and in the rock flow that was divided, a stone with a pitch-black body and flashing golden-red light flew out of it, and flew straight towards the little leopard.

Golden-red, like gold but not gold, like stone but not stone, and the shape is also very irregular, presented in front of the leopard's eyes.

I don't want to think about the little leopard's fingertips lightly. A ghostly thought fluttered towards the strange substance.

This was exactly one of the little leopard's thoughts.

This level of strange things little leopard understands tightly. It's already psychic, it's just the last threshold, if you give it another thousand eight hundred years, you can definitely evolve your sanity, but now, it's cheaper for him.

Such a strange thing that is about to evolve its sanity does not reject the idea, and it can even be said that as soon as the idea of the little leopard is entered, it immediately blends with this mysterious thing, regardless of each other.

Under the control of the little leopard, the light on the surface of this thing gradually faded, revealing a cold and hard shell, and the volume began to change, and finally it shrank into a fist-sized one. A black "stone" that looks like a boulder

"It's a good thing, but I don't know how to use it, so let's put it first!" said secretly to the little leopard in his heart, because the volume of this thing does not take up much space, so the little leopard directly threw it into the space that was divided by himself and put two big hammers.

Although the two hammers are large enough to fill the entire space, it is more than enough to put a fist-sized stone!

After doing all this, the little leopard breathed a sigh of relief gently, and untied the technique of dividing the two realms just now, the Black Sun Fist intent rose behind him, and the originally smooth flow of the earth's core rock flow began to boil under the influence of the Black Sun Fist Intent, and bubbles the size of fists emerged from the bottom of the rock flow.

"Okay, it's time to cultivate, just see if I can break through this time!"

Yesterday's Zhongyuan Ghost Festival, I was pressed by ghosts three times at night. Not a good sign!
