After the negotiations were completed, Tang Jie followed Na Xi Canhen into the mine cave. As for Qiu Shuyu and others, they did not follow due to the rules.

Some miners in the mine were still walking around with mine baskets on their backs, but the narrow mine tunnels led to the unpredictable darkness.

It is said that for this spirit stone vein, the Shimen Sect almost dug the mine channel deep into the abdomen of the mountain. Now the periphery of the mine has been hollowed out, and it is as bright as a hall in the mountains. If miners want to dig enough spirit stones, they often have to walk along the mine channel for a long time.

The mine walls around the mine pit were reinforced by cultivators with earth-based spells. After confirming that the mines in this area have been dug, cultivators will seal them with earth-based spells to prevent collapse. However, according to the rules, there will be a certain gap at each blocking and reinforcement point, which is convenient for spiritualists to investigate.

At this moment, as Xi Canhen walked a few steps in the hall, Tang Jie came to a rock wall, reached into the gap, and placed his hand in it, activated the spiritual energy. A trace of spiritual energy penetrated through the gap, and felt the energy fluctuations after feeling the barrier.

After exploring for a while, Tang Jie only felt a little bit of extremely weak energy fluctuations, knowing that it was just some residue that was not worth digging, and this rock wall had indeed been hollowed out.

This is not surprising. This is the entrance of the mine cave, which is the most unlikely place to be missed. Tang Jie investigated here, mainly to feel the feedback of the soil and spiritual energy here.

After trying, Tang Jie took out the mine pit map, wrote a few strokes on it, and said to Xi Canhen: "Let's go."

The mine pit map was an early map. As the mine tunnel was dug later, the map gradually could not keep up. Therefore, even if there was a map, Tang Jie still needed to find a guide to move forward accordingly.

He was not afraid of getting lost, but if he was dizzy, he didn't even know where he had been. If he missed a certain point and there was a batch of ore behind this point, it would be a loss for the Moon Washing School.

Tang Jie's instructions to Xi Canhen were: use the shortest route to walk every mine path.

At this moment, the two continued to move forward. Every time they walked a distance, Tang Jie would stop and carefully search each mine wall without missing any.

Under the dim light, the two of them moved forward step by step.

The more you go, the more rugged the road becomes, and as the forks gradually increases, fewer and fewer people meet. At first, you can see some miners squatting in front of broken stones looking for the raw stones. They are cautiously alert to everyone who is approaching them. Gradually, there are fewer and fewer miners, but occasionally you can hear the sound of mine picks hitting the rocks in the distance.

"Didn't it mean that the deeper the mines, the more mines they get? Why are most miners concentrated in the middle and back sections, and when they go deeper, there is no one?" Tang Jie asked.

The boy replied without looking back: "Because there are monsters in the deepest part."

"Monster?" Tang Jie was shocked: "You said there are monsters in the mine? Then why didn't you find the spirit master of the Stone Sect to take action to eliminate monsters?"

"I've been here." Xi Canhen replied: "It's a pity that it's useless. Once they come, the monster disappeared and did not appear at all, just like they could find them."

After Xi Canhen’s account, Tang Jie understood.

It happened about two years ago that the mine was in trouble.

That day, the miners were mining on various mine tracks deep in the middle, and suddenly they heard a scream. When the miners arrived with the screams, they found that there was only a pile of blood on the ground, but one of the miners had completely disappeared.

Shortly after that, three more miners disappeared in succession.

It was at that time that the Shimen Sect sent people to investigate, and this was their first time.

However, after investigation, the people from the Shimen Sect found nothing.

However, with the departure of the disciples of the Shimen, the incident of monsters appeared again, and it appeared even more fiercely.

This time it appeared directly - someone saw the monster with his own eyes.

Tang Jie asked: "You said someone saw the monster with his own eyes but did not die?"

"Yeah." The boy nodded: "And there were more than one person, and about ten people saw it in front and behind. He said that he had thick long hair, about three meters high, extremely powerful, and had sharp claws. He could make a big hole in the rock wall in one go. He could drill into the ground, and by the way, he could also swallow the original ore."

"Long hair, three meters, sharp claws, great strength, drilling into the ground, swallowing raw ore... What kind of monster is this?" Tang Jie thought repeatedly, but he didn't expect any kind of monster like this. However, there are all kinds of monsters in the world, and grass, trees, and raw stones can become essences. Even if there is something that he has never seen before, it is not uncommon. Not to mention himself, even the great master of Xiyue dare not say that he is used to seeing strange things in the world.

"Then later?" Tang Jie asked.

The young man shrugged: "What else can it be done? I'll inform the Shimen Sect again. But the monster is really cunning. As long as the people from the Shimen Sect come, they will immediately lie dormant. This is a mountain, and it can drill into the ground. If it doesn't come out, unless the entire Yongsui Mountain is lifted up, the Shimen Sect will have no choice. Later, the Shimen Sect simply sent his disciples to pretend to be miners, restrain their breath, and wait for the monsters secretly. As a result, they were really waiting for one time. A Shimen disciple fought with the monsters, but unfortunately they couldn't kill the monsters.

, the monster was slipped away by the monster before the Shimen reinforcements arrived. However, the disciple also learned some situations, saying that the monster should have some ability to draw its own territory, and any life that enters its territory can be discovered by it. Therefore, it is very difficult to encircle and suppress this monster. In addition, the method of impersonation has been used, and the monster suffered a loss, and it is almost impossible to catch it. However, as long as it is outside the territory of the monster, the monster should not be easily dispatched."

"So the miners stop digging deeper into the mine?"

"Yes. Fortunately, the monster was released late, and the mines that were easy to dig deep in the deep have been dug. In addition, its territory is not large, so although it will miss some ore, the loss is not too great. Moreover, sometimes there will be brave miners sneaking over and knocking them a few times and stealing some raw ore out. As long as the movement is not too great, the monster will ignore it."

As he said that, Xi Canhen looked back at Tang Jie: "The reason why I get the most raw ore is because I sneaked in the most times. Maybe it's because I'm too small, and every time I go in, the monsters don't eat me."

"So that's how it is..." Tang Jie made a long tail sound and his eyes narrowed slightly.

After walking for another period, Tang Jie and Xi Canhen have reached the deepest point.

At the end of the mine channel is a bottomless abyss. Looking from above, it is pitch black inside the abyss and nothing can be seen.

"This is the end of the day." Xi Canhen said: "The mineral veins end here. There are still some raw ore on the rock walls here, but there is the monster underground. The miners dare not come easily. If you weren't there, I wouldn't dare stand here. I used to be on the edge of its territory, pick some and run away."

The ore walls in this area were not blocked. Tang Jie stretched out his hand and found that there were indeed large areas of energy fluctuations behind the rock wall, which confirmed that there were indeed many raw ore here.

This is also the last surplus place for this ore vein.

According to the Shimen Sect, after the ore in other places is mined, the Shimen Sect will personally send disciples to guard the place and dig the remaining mines. What Tang Jie has to do is to report the number of discovered remaining mines. After the Xiyue Sect collects his own portion, he will no longer have to pay attention to this ore vein.

To confirm that the remaining mine is simple, it requires the cultivator to worry about the specific amount of the remaining mine, and to detect it with all his energy. However, Tang Jiewu's wisdom palm insight was only a trivial matter for him, so if he only uses his energy, the original ore behind the rock wall will be roughly clear.

After counting the number, Tang Jie took out a black stone: "What about this one?"

This black stone is what Xi Canhen gave him before, and it is also the core key to the young man being able to open the Jade Gate, and it is also the key to moving Tang Jie.

Xi Canhen pointed to a rock wall not far away and said, "It's right here. That day I came over to steal the ore and happened to see a bare raw ore in front of me. For the miners, the exposed raw ore is like gold on the ground, so I went over without any danger and mined the raw ore, and took it out. I saw that the stone was a little strange, so I took it back. I didn't expect that my whole body was hot that night, and something seemed to rush around in my body. Later, I felt much more powerful..."

"It's true." Tang Jie murmured.

"Do you know what this is?" Xi Canhen asked. Since he got the black stone, he felt that his body had changed significantly and was curious about what this was. But he knew that he did not have the ability to keep the secret and did not dare to reveal it. It was not until Tang Jie saw his secret that he was forced to say it. Now that Tang Jie has known it, he naturally wants to ask clearly.

Tang Jie did not hide it from him: "This is a crystal-turned sand silkworm."

"Sand Silkworm? Are you saying this is not a stone, an animal?" Xi Canhen asked in surprise.

"Yeah." Tang Jie nodded: "To be precise, it is a sand silkworm that has become a stone, and it is a rare material in the world of cultivation."

The exact name of the sand silkworm is actually called the spirit-eating sand silkworm, which is an extremely rare monster insect. The biggest feature of this kind of monster insect is that it is addicted to eating spirit stones. The lifespan of a sand silkworm is generally about 500 days. During these 500 days, it desperately devours spirit stones at a speed of two kilograms a day. It can swallow about one thousand kilograms of spirit stones in its lifetime. It is converted into a spirit stone that is one hundred spirit stones.

With such a terrifying appetite, the sand silkworm does not waste a trace of spiritual energy. Except for those meaningless residues, every bit of spiritual energy is in its body. The reason for this is that the sand silkworm has a special ability, namely, spiritual energy crystallizes. However, as the sand silkworm swallows more and more, the crystallized spiritual energy becomes more and more fierce. In the end, the entire body of the sand silkworm will completely crystallize, which forms the black stone in Tang Jie's hand.

For practitioners, it is the supreme treasure.

Because it is an important material that can increase the spiritual energy reserves of cultivators.

For practitioners, due to innate limitations, practitioners can only liquefy spiritual energy.

For example, at the peak of the Spirit Sea, ten thousand drops of spiritual liquid are manifestations of spiritual energy liquefaction. Even the cultivator who has escaped from the mortal world can only use the spirit in his body to activate the spirit of heaven and earth. However, his own spiritual reserves are actually the same as those of the peak of the Spirit Sea students, and there is no change, because this is the limit of the human body.

If the spiritual energy can crystallize, the magic power of the cultivator will undoubtedly be greatly improved. Unfortunately, the innate limitations of the human body make it almost impossible for the cultivator to crystallize spiritual liquid.

Crystalized sand silkworm is a treasure that can make up for this regret. It can help cultivators generate structures that can crystallize spiritual liquid in their bodies, crystallize some spiritual liquid, thereby increasing spiritual energy reserves.

Of course, cultivators cannot crystallize all spiritual liquids because of this. It will only make cultivators like mortals swallow gold, fall into the spirit sky and die. Therefore, the spiritual sea is still the basis, and crystallization is only for assistance, just like an iceberg in the sea, which is limited to improvement.

Although it is limited to improvement, it is the total amount of spiritual energy that has been improved, and its value can be imagined!

For this reason, crystallized sand silkworms are a hundred times rarer than spiritual ore, and almost every piece can be sold at a sky-high price on the market.

Like the crystalline sand silkworm in Tang Jie's hand, if used properly, it can help Tang Jie form a crystallization structure of about 300 points of spiritual energy. The crystallized spiritual energy that a cultivator can accommodate is about 30% of the upper limit, which means that ten crystalline sand silkworms can increase Tang Jie's total magic power by 30%, which is quite amazing.

Such a terrifying spiritual content and quality is normal to help Xi Canhen break through the Yumen, but this kid is also lucky. Although the crystal-formed sand silkworm can help break through the Yumen, the danger is not low. If he does not die, he is lucky. It is rare that under no guidance, this little guy has reached the sixth level of the Yumen. Tang Jie asked, and then he realized that this kid is stubborn by nature. Although his whole body was in pain at that time, under no guidance, he did not say a word based on his nature alone, and did not waste his talent at all, which made Tang Jie admire him.

At this moment, Xi Canhen also knew the meaning of the sand silkworm and was stunned: "Then isn't this thing very valuable?"

This is the first thought that popped up in his mind.

"Yes, in the cultivation world, a crystalline sand silkworm can be sold at least 100,000 yuan, but it still has a price but no market." Tang Jie replied: "But because you are not properly maintained, your value has been reduced a lot... You are extravagant to use the crystalline sand silkworm to rush into the jade door, but it is not completely useless. At least your body is strong."

Xi Canhen had never learned the magical cultivation technique, and the excess spiritual energy had nowhere to go, so he spontaneously nourished his body, making the boy's body strong, otherwise he would not have defeated the four strong men.

"100,000 spiritual money." The boy's eyes were almost spitting out of fire when he looked at Black Stone.

"What? Do you regret it?" Tang Jie asked with a smile.

The boy thought about it and replied: "It's just a pity, but it's nothing. If you don't tell me, you won't know. You will only waste good things in vain."

"I'm still a sensible person." Tang Jie nodded with satisfaction, and suddenly shook his hand and gave the crystal-shaped sand silkworm Xi Canhen.

Xi Canhen looked at Tang Jie in confusion, and Tang Jie said: "Any life will not exist alone. There are often ones and twos. So if you can have a crystalline sand silkworm, there will be a second and third... All I want is the place where they exist. As for this, I will give it back to you, so that you can think that my dignified cultivator is cheating on you, a little child."

Xi Canhen shouted: "I'm not a little broken child!"

However, his hands and feet quickly put away the crystalline sand silkworm, and his eyes showed a hint of gratitude.

Only then did Tang Jie continue to explore the mine wall, looking for crystal-formed sand silkworms.

However, no matter how hard Ren Tangjie tried, he couldn't find a piece.

This made Tang Jie very puzzled. Although the crystal-formed sand silkworm has very little energy to escape due to crystal-formed sand silkworms, and there are spiritual stones everywhere behind the rock walls, their energy fluctuations are more easily disturbed, Tang Jie is a person who understands and understands, and is confident that if there is really a sand silkworm in this area, he will not be able to find it.

Is this really the only one sand silkworm?

This is not impossible. The sand silkworm is escaping from the soil and rushing to the spirit mine for a hundred miles a day. If it is just an alien sand silkworm who finds the ore veins here to come to eat, although the chance is a little smaller, there are precedents to follow.

Or has it been mined by the previous people?

This is not impossible.

In fact, supervisors must steal themselves. This is a common thing in the cultivation world. Even the Xiyue Sect does not think that the Shisect will be clean, but everything needs to be moderate. As long as it is not done too much, the Xiyue Sect usually turns a blind eye, just like the Shisect party is Wu Xiucai turns a blind eye.

But sand silkworms are a big deal. If this is the case, they will steal it themselves. Once it is spread, it will be a disaster for the family to be destroyed.

Moreover, it is difficult to keep this kind of thing secret. After all, after the crystalline sand silkworm comes out, it will either use it for its own use or sell it outside. No matter which choice it is, it will be big news when it is spread. As long as there is no exact origin, major sects will definitely pursue its source. It is difficult for the Stone Sect to hide it.

However, since the monster incident, no miners have come to mine the rock walls here. The rock walls are intact. If someone secretly stole them, the rock walls will not be kept so complete, and it is even more impossible for miners to not know.

Or... Actually, this is not a nest for sand silkworms?

Tang Jie turned his head and looked towards the abyss at the end of the mineway.
To be continued...
