The rough stone mines are not all open-pit mines, except for the veins in the mountain, these rough stones are embedded in the mountain, at all depths, and the exposed surface of the mountain has long been emptied, and can only be found and mined everywhere by experience. Therefore, after entering the mining area, there are shallow or deep mine holes everywhere, there is no law at all, and when you find a vein, you will dig it indiscriminately, regardless of whether it is wasted or not, Bei Mingxuan couldn't help but shake his head.

When they arrived at the mining area, the jade miners gradually dispersed, digging stones and mining in groups of three or five, and from a distance, it seemed that each of them had a harvest. Du Chun had been with Bei Mingxuan at the beginning, but looking at his aimless actions and clumsy digging techniques, he had no gains after half a day, and he gradually separated.

Traces of indiscriminate mining on the mountain can be seen everywhere, and the full set of skills of the North Ming Xuan is to go up and touch the stones when they see them, and finally find 2 pieces of rough stones that are not too big or small, but the jade quality is still passable, so the back basket of the North Ming Xuan and the Fan is still empty. Turning to the back mountain, he saw a mountain col, Xiao Yan suddenly flew over from the col, and chirped happily in front of Bei Mingxuan. Bei Ming Xuan Daxi waved his hand, Xiao Yan slid through a graceful arc in the air, and flew into the mountain col again, and the two of them rushed to follow.

After a while, the two of them came to a place at the end of the col that looked ordinary, but the entrance of the cave was obviously old and tall. Xiao Yan didn't wait for Bei Mingxuan to speak and flew straight into the cave, the two followed up in the mine, and found that this mine was a large mine that had been properly mined, the mining surface was neat and orderly, the incision on the stone wall was very flat, and the entire mine was 5 meters high and 6 meters wide. Bei Mingxuan took out a strong flashlight and carefully looked at the mining traces, it seems that it has been some years, at least more than a thousand years of mining history, which can be proved by several or even more than a dozen theoretical bases for the mineral knowledge of Bei Mingxuan. But so many years ago, did there be such technology, tools, and manpower to do mining on such a scale?

Bei Mingxuan couldn't help but say loudly: "Impossible, right?"

Lifan asked, "Brother, what's wrong?"

Bei Mingxuan shook his head and sighed: "Looking at the traces of mining for more than a thousand years now, but it is really incredible that people thousands of years ago could mine such neat mines. ”

He had no idea about any of this, and shrugged his shoulders to indicate that he could not answer. Not to mention the jade in the mine, even the ordinary jade material did not leave a penny, but Xiao Yan did not hesitate to fly in the mine. The deeper the tunnels go, the more criss-crossed, chaotic, and lower and lower. Xiao Yan's speed is extremely fast, and the speed of the two of them is no longer slow, but they are still gradually unable to keep up. Finally, an hour later, the two of them stopped and sat down on the ground panting. Xiao Yan flew back again, and when she saw the embarrassment of the two, she chirped to express her dissatisfaction. After a little rest and recovery, they got up again and walked with Xiao Yan, unconsciously going deep into the depths of this ancient mine.

After turning more than a dozen extremely long mine roads, Xiao Yan stopped in front of a stone wall, screamed a few times at the stone wall, and stopped on a raised stone block opposite the stone wall. Bei Mingxuan irradiated it with a flashlight, and found that the stone wall was the end of this mine, and compared with the previous mine, this mine was not standardized and neat, and it looked hasty and disorderly.

He stepped forward and touched some of the fine jade materials left on the stone wall, could it be that the ancient jade mine was mined here and stopped because of some change? Xiao Yan is a psychic bird, in the jade shop of Longzai, it is it that it found this piece of the best southern jade that is still in the Bei Ming Xuan's satchel, so the North Ming Xuan is still very much looking forward to Xiao Yan. He took out the pickaxe and excavated the remnants of jade on the stone wall, and Lifan also stepped forward to help. After a while, Bei Mingxuan suddenly stopped Fan, because he found that the back of this stone wall was actually hollow, and carefully determined by tapping that there was a hole one meter wide and one meter five high less than 3 meters behind the stone wall. Two noble ancient martial arts cultivators transported the internal force that martial arts enthusiasts could not see and hear in their lives, and became hard-working miners.

In less than an hour, there was a pop, and the stone wall was pierced, revealing a smooth passage. The two of them bowed their heads and walked forward for twenty meters, and then Huo Ran became cheerful, the height of the passage was more than two meters, and the width reached one and a half meters. After the two walked more than 100 meters, there was a huge stone room, a huge stone platform of more than 10 meters in the stone room, and there were forty or fifty stone benches around it, and there were thick jade chips on the platform and on the ground. It seems to be a place for the initial processing, cutting and decomposition of the quarried jade, which is obviously not the previous jade mine, and should be connected to another large jade mine.

Could it be that in ancient times, jade materials were all processed in caves? It doesn't make sense, this location is the depth of the cave, and if you want to process it, it should be close to the exit, is it necessary to bother to excavate such a large stone chamber in such a deep stone mountain? Looking at the passage and the stone walls of the stone chamber, they have been carefully polished, and they are extremely smooth and smooth, is it necessary to spend so much manpower and material resources? Bei Mingxuan kept shaking his head gently.

There is also a passage at the other end of the large stone chamber, which is more than 30 meters long, and there are six stone chambers neatly distributed on both sides. The stone door opens and closes, and the seemingly heavy stone door opens and closes, but it is quite agile. Behind this group of stone chambers, this passage goes straight into the distance, and the strong flashlight cannot shine to the end, and I don't know where it leads. Bei Mingxuan curiously looked at the stone rooms one by one, there was a large stone room with a huge stone shop in it, which was supposed to be a place for the miners to rest, and the four small stone rooms were a single stone bed, there were no tables and chairs in front of the bed, only a moldy futon, which should be the place where the jade mine managers rested. Each stone chamber seemed dry and airy, and in the air, Bei Mingxuan felt a much richer Heaven and Earth Yuan Qi than the outside world.

The stone door of the innermost stone room was closed, and the two of them could not open it by all means. Bei Mingxuan was pondering the way to open it, Xiao Yan couldn't bear it, and flew forward to grab it, and the two of them were surprised to see that the stone door was extremely hard, and it was actually grabbed by Xiao Yan A piece of stone. Xiao Yan chirped, reminding the two of them that they didn't have to be polite, and it was not their own property. Bei Mingxuan and Lifan then took turns to pick up the miners for the second time, the stone gate was far less thick than the previous stone wall, and it didn't take long to dig a big hole, and both of them and Xiaoyan drilled through.

The stone room is more than 100 square meters in size, which is full of rows of wooden frames, and the four walls of the stone room are also carved with stone lattices. In the right-hand corner of the door, there is a stone table and a stone chair, and there are several empty drawers under the stone table, and there are several animal skin rolls in the top empty drawer, and a cloth bag is placed in the corner of the bottom empty drawer. Bei Mingxuan took out the things in the empty drawer and put them on the stone table, Xiao Yan flew to the table and stopped, staring at the small cloth bag, and his little head turned around to look at it. Bei Mingxuan picked up those few animal skin scrolls and looked at them carefully, there were some ancient words and numbers written on them, this kind of knowledge in the sea of consciousness of Bei Mingxuan was completely unhindered, although he read it slowly, but it did not hinder him. Here are a few running accounts, which read:

In the year of Yichou, on the third day of the month of the monkey, it was harvested:

50 pieces of spirit stones (lower grade);

5 spirit stones (medium grade);

1 spirit stone (top grade);

3 pieces of yuan jade (lower grade);

High-grade jade: 15 squares.

...

On the fifteenth day of the month of the dog, the following was obtained:

48 spirit stones (lower grade);

6 spirit stones (medium grade);

0 spirit stones (top grade);

Yuanyu (lower grade) 5 pieces;

High-grade jade: 11 squares.

...

The time on the hides is not continuous, and there are traces of alterations, so it is believed that the ledger was discarded when it was filled out. As for the spirit stone and yuan jade, I don't know what this refers to, but it can be speculated that since it is mined with the jade mine, it must be something that is born with the jade mine. Since it is called Lingshi and Yuanyu, the cool aura contained in the best Nanyu contained in the best Nanyu is either called aura or vitality.

It seems that this ancient jade mine is by no means as simple as an ordinary jade mine, at least it involves those ancient martial arts cultivators in the ancient era, because whether it is called aura or vitality, the best southern jade is obviously helpful for ancient martial arts cultivation. He handed the animal skin scroll to Fan, who had just gone to find all the wooden frames and stone lattices, and he should have found nothing when he saw that he was empty-handed. Lifan flipped through the animal skin scroll and looked at it over and over again, and he didn't recognize any of the ghost-like characters on it.

Bei Mingxuan picked up the small cloth bag, the cloth bag was only a few feet long, the mouth of the bag was no more than the size of a cup, and a rope of unknown material tied it firmly. The cloth bag and rope have not rotted for so many years, and they are not ordinary things. He casually untied the mouth of the bag, looked inside, the mouth of the bag was gray, he couldn't see what was inside, he reached out and tried to reach in and touch, but he couldn't get in at all. Bei Mingxuan was shocked, shook the bag, the bag seemed to have nothing in it, and Li Fan also put aside the animal skin roll at this time and looked at Bei Mingxuan, Bei Mingxuan threw the cloth bag to him, and after trying it, his face also changed greatly. What is the situation? A small cloth bag that looks ordinary has such a strange situation, Bei Mingxuan couldn't help but take out a knife and wanted to cut open the cloth bag. Xiao Yan screamed, flew over and took the cloth bag away, his eyes full of reproach.

Bei Mingxuan looked at Xiao Yan embarrassedly and said, "Xiao Yan, there's nothing in here, I can't even put my hand in..."

Before he could finish speaking, Xiao Yan flew up and sent the cloth bag to his forehead with his mouth, Bei Mingxuan hurriedly supported Xiao Yan with his hand, and Xiao Yan nodded on his Yintang acupoint with his mouth. Bei Mingxuan took the cloth bag with his other hand, nodded thoughtfully, and put the cloth bag into the satchel, now the treasure hunt is important, and there is no time to study this cloth bag.

Bei Mingxuan asked Fan: "Let's go to the jade mine here?"

For half a day, they really didn't gain anything except digging a few pieces of jade that looked good from the stone wall blocking the passage. Fan nodded, he had always looked at the head of the Northern Hell. Xiao Yan didn't want to leave, so she suddenly jumped off the table and kept spinning around the bottom of the table. After a while, Xiao Yan firmly screamed excitedly at the bottom of the stone table, and began to dig the ground under the stone table with his steel claws. Bei Mingxuan stepped forward to check, this stone table was carved from the original stone when the original stone room was excavated, and the stones at the bottom of the table and the ground were originally one, since Xiao Yan thought that there was a treasure below, he did not hesitate to call Fan, knocked down the stone table, and began his third miner career.

These stones were extremely hard things, and if it weren't for the fact that both of them were ancient martial arts cultivators with internal strength, it would have been impossible to dig up the previous stone wall and the stone door of this stone chamber in a short period of time. Even so, the stones under the stone table still made the two of them sweat all over, rested three times, and finally chiseled through with a pop after digging more than ten meters. Immediately, there was a strong cool aura in the face, and the two miners suddenly felt refreshed, and the fatigue of their bodies was relieved a lot, and Bei Mingxuan was even more motivated. After a while, after digging a hole large enough for a man to burrow, the two of them jumped into a spherical closed stone cave, which was not large, but only 3 meters in diameter.

As soon as he jumped into the cave, Bei Mingxuan saw that the fluorescence in the cave was faint, and the stone walls of the entire stone cave were crystal top quality southern jade, which was inlaid with jade that was brighter than the best southern jade, and the surface flowed with milky white spiritual light, and the concentration of cool aura in the entire stone cave was so high that it almost condensed the spiritual mist. These were not the most magical and attention-grabbing places for the two of them, who were leaning against the cave walls, all staring intently at an illusory light suspended in the middle of the cave.

Light and Shadow is a magical creature that has never been seen before, with the same dragon head as in the legend, two deer antlers with forks on the head, two feet long whiskers on the long mouth, a pearl of light under the jaw, a purple scaled snake body, the tail is divided into three fins like a fish, and the abdomen has 4 dragon claws divided into five toes, which is no different from the legendary dragon. But it has two pairs of colorful butterfly wings on its back, two large and two small patterns are mysterious, giving people a gorgeous and abnormal feeling, and it is a dragon with butterfly wings!

Bei Mingxuan muttered: "Phoenix Bird Nirvana Dragon Butterfly Dance, this is a dragon butterfly?"

The few verses that Elder Yuankong had chanted before he parted naturally appeared in his sea of consciousness, and he turned his head to look at Xiao Yan, who nodded to him. Bei Mingxuan shook his head a little confused, and looked back again at the dragon butterfly in the light and shadow, and found that the scales on its body were not like fish scales, but peculiar purple, and the scales were hexagonal, feeling thick and hard. Bei Mingxuan looked at these scales and suddenly had a sense of déjà vu, by the way, it was the strange insect in the secret valley of Yuexiu Mountain, he found a few residual scales when he searched the scene of the fight between the strange insect and Xiaoyan in the secret valley, and those scales were very similar to the scales of the creatures in the light and shadow.

Suddenly, the dragon butterfly in the light and shadow suddenly opened his eyes, is this light and shadow actually a living thing? Bei Mingxuan was shocked, and after opening his eyes, the dragon butterfly showed a look of surprise, and slammed into Bei Mingxuan, flying around in front of him, bringing out phantom shadows. Suddenly, it stopped in front of Bei Mingxuan's chest and stared at a place on Bei Mingxuan's chest, Bei Mingxuan reached out and touched it, where he put the strange insect eggs. After the eggs sucked a lot of his sperm and blood last time, under Xiao Yan's prompting, he kept the eggs in the pocket of his clothes close to his chest.

The strange insect stared at it for a while, opened its mouth and took a deep breath, and the cool aura in the stone cave surged into the dragon's mouth as if it had been summoned, including the cool aura that escaped from the circular stone cave they had chiseled through the circular stone cave. With so much aura pouring in, I didn't see the light and shadow of the dragon butterfly getting bigger, but the light and shadow became much more condensed.

Without waiting for the North Styx Xuan and them to react, after the dragon butterfly sucked the light and shadow, he put the dragon's mouth to the strange insect eggs on the chest of the North Styx Xuan, and spewed out the cool aura. The air flow through the clothes sprayed directly onto the eggs, and the eggs suddenly became hot, and also flashed with a shining light, inhaling the air flow of cool air, and sucking as much light and shadow as it sprayed, as if it was a bottomless pit. After spraying this long breath of cool aura, the light and shadow were obviously dimmer than before, but the expression on Long Die's face was extremely excited and joyful. The eggs in the chest pocket of Bei Mingxuan disappeared after absorbing these cool aura, and the temperature returned to normal, and there was no abnormal movement.

I don't know if it was affected by the cool aura of dragon butterfly light and shadow, the green vine treasure in the dantian of the Northern Darkness Xuan suddenly emitted bursts of golden light, and the golden light flashed out from the Yintang acupoint in the heart of the forehead. The dragon butterfly's face immediately froze, and a pair of dragons' eyes became even more round, full of incredible expressions, followed by an expression of extreme surprise, and rushed towards the golden light without hesitation, bathed in the golden light. The light and shadow of the dragon butterfly writhed comfortably in the golden light, and the butterfly wings on its back were constantly flapping gently, which seemed to be very enjoyable. After a few breaths, the golden light rolled back, and the dragon butterfly light and shadow followed the golden light through the Yintang acupoint into the head of the Northern Immortal Xuan, and entered the upper dantian. In the consciousness of Bei Mingxuan's inner vision, he brushed into the mouth of the automatically opened green vine treasure gourd and disappeared without a trace.
