After Yi Shui and the others sent away the people who came to recruit from the Three Ghost Sects, they finally went back to continue their work. And Ye Chen didn't know about this matter at all, and even if he knew, he didn't care, at this moment he was being troubled by something.

"How can there be a cave here?"

At this time, Ye Chen stood in front of a cave with a shocked expression, looking at the cave in front of him with a surprised expression. When he was practicing swordsmanship, he inadvertently smashed the wall, and as he practiced, he found that he had unintentionally opened a cave. He was very surprised, he never thought that there would be a cave here, could someone dig it?

In front of him, there was a hole half a meter wide, and it could be seen that the black mist was tumbling inside, and there was a ghostly aura sweeping out. What's even more surprising is that it is accompanied by a strange breath that makes people addicted for a while.

"Strange, how do I feel a sense of longing to go in?"

Ye Chen's expression changed, and he exclaimed, almost thinking that he was delusional, but finally sensed a mysterious aura coming from the cave. It was this mysterious aura that gave him a desire to enter, as if something inside was tempting him.

"Would you like to go in and have a look?"

Ye Chen's face hesitated slightly, and finally gritted his teeth and muttered, "If you don't enter the tiger's den, you will get a tiger?" I'll go in and take a look, what the hell is going on." ”

Click!

With a push of his palm, there was a click, and the half-meter-wide hole in front of him suddenly cracked. Then, with a bang, the wall collapsed, creating a hole that could accommodate one person in and out, and the figure entered the hole with a single drill.

"This?"

As soon as Ye Chen entered it, he found that there was a passage on the left and right sides, which was very spacious. At this glance, it is obvious that he came out of the middle, that is, this passage was dug from somewhere else, and he just accidentally discovered it.

"Who dug the passage?"

Ye Chen frowned slightly, muttered, and said, "Could it be that other forces want to dig out the channel for dividing ore veins like us?"

Crash!

He turned around and waved his hand, and a surging ghostly aura gushed out, and in the blink of an eye, the hole that came out was submerged. The ghostly aura was surging, tumbling and boiling, and then a raging flame burst out, finally enveloping the front.

Call!

As Ye Chen dispersed the blazing ghost fire in front of him, a wall was finally revealed, which merged with the surroundings, and he couldn't see anything strange in it. He was temporarily sealing the cave he had come from, just in case other ghosts passed by and would find it.

"Let's take a look!"

After Ye Chen did all this, he instantly decided in his heart to take a look at those other sub-ore veins, so he didn't hesitate to turn around and walk in the direction of that strange aura.

Ye Chen walked cautiously all the way and found that this tunnel could accommodate five people, and the walls of the four sides were full of potholes, and it was clear at a glance that someone was digging out. Moreover, there were a lot of gravel scattered on the ground, and what surprised him even more was that there were also a lot of tiny soul crystals mixed in them.

"What a ghostly aura!"

Ye Chen followed and found that the further he went, the stronger the ghost aura of the cave ** became. The black air is billowing in front of you, and the ghost fog is sweeping in, making people feel very comfortable when they take a deep breath, which is the feeling of a ghost.

"Could it be that one of the sub-mines has a high-grade soul crystal?" he thought in surprise as he walked.

Ye Chen had learned about it over time, and finally figured out the grade division of this vein soul crystal. The sub-vein where they were originally located only produced primary soul crystals, and after coming to the main ore vein, most of them were intermediate soul crystals, and a small number of high-level soul crystals. However, it was a pity that he had never seen a high-grade soul crystal, and the highest was only the middle-grade soul crystal they had excavated.

"Maybe you can get some high-grade soul crystals to cultivate!"

He muttered as he walked, his face fluttering, his steps light, and he quickly passed through the thick ghost mist. His figure was illusory for a while, as if he had melted into the void, but the ghost mist rolled back and forth from time to time, making it difficult to distinguish.

Ye Chen held the pitch-black ghost sword in his hand and walked cautiously towards the front of the cave, his soul thoughts emanating out, sensing all the movements in all directions. He felt that breath getting stronger and stronger, and there was a surging longing in his heart, as if there was a call tempting him forward, very strange.

"What a weird feeling!"

Ye Chen's expression was awe-inspiring, and he was on guard as he walked, and his inner vigilance was raised to the limit. From this strange aura, he couldn't distinguish any information, and if something was abnormal, it would be a demon, which made him very vigilant.

Syllable!

Suddenly, a fist-sized object slipped from the top of his head, and it alarmed Ye Chen with a snap. He was instantly alert, and when he looked closely, he found that it was a crystal stone with a whole body, the light was shining, and there were wisps of ghost qi swirling, but this was a soul crystal the size of a fist.

Call!

Ye Chen breathed a sigh of relief, muttered, and said, "Startle me, it turned out to be an intermediate soul crystal." ”

He raised his head slightly, and the whole person was stunned for a moment, only to see that the top of his head was inlaid with one crystal after another crystal crystals. They vary in size, from the size of a human head to the size of a thumb, and the small ones are the size of a thumb. 120

"Why are there so many?"

From the aura of the soul crystals above his head, Ye Chen could tell that these were all intermediate-grade soul crystals, which surprised him. followed by a heartbeat, thinking about whether to take them down, after all, this is also a rare soul crystal.

"Forget it!"

Ye Chen finally rejected this idea, he continued to walk forward, after all, he was here to check, if something went wrong with one of them, it would be troublesome.

In the billowing black mist, a faint shadow was moving rapidly, as if it was fused with the surrounding ghostly energy. Ye Chen kept walking forward, feeling that strange aura was getting stronger and stronger, and there was a rush in his heart.

The long cavern seemed to have no end, only the ghostly energy swept and the mist rolled. From time to time, there was a gust of yin wind whistling, this discovery made Ye Chen look puzzled, where did the yin wind come from here?

"Is this a passage beyond the veins?"

Ye Chen's expression suddenly became excited, and he wondered in his heart whether this passage was leading beyond the ore vein. If that was the case, then they would be able to escape the cage and be free, and at this moment, his heart was excited.

He forced himself to endure the excitement in his heart, and muttered: "I can't be impulsive, I can only be sure of one first, otherwise I will be in vain." ”

Although he guessed that it might be a passage to the outside of the ore vein, Ye Chen still resisted an impulse in his heart. He needed to see what was going on before he could draw a conclusion, and besides, he needed to find out if there was any danger hiding.

Ye Chen looked around in surprise as he walked towards the front of the cave, and he found a lot of soul crystals scattered on the ground. This discovery suddenly lifted his heart again, and it all seemed very wrong.

"Why so many soul crystals?"

His face was serious for a while, and he watched as the cave was surrounded by a large number of soul crystals, of different sizes, and was gushing out one after another of rich ghost qi.

Call!

A yin wind blew on his face, and Ye Chen, who was startled, was cold, and he looked ahead, but he didn't find anything. The black fog in front of him was filled, and the ghostly qi was rolling, like a raging wave, sweeping in wave after wave.

"Where the hell does this lead?"

Ye Chen was completely confused, and from that surging ghost aura, he felt an even stronger aura. It was that strange aura, as if there was an inexplicable force that lured him in, which was very weird.

Brush!

As soon as he stepped out, his figure moved naturally, and disappeared with a brush. Ye Chen's figure was ethereal, moving quickly forward like an illusory shadow, and the whole person seemed to be contained in the surging ghost qi.

This was his ghost step, and after a long period of cultivation, he finally reached a point where he disappeared without a trace. It is no longer a shadow like before, but like now, it seems to merge into the surrounding ghostly energy, which is difficult to distinguish.

Ye Chen found that the further he went into the entire cave, the narrower it became, and it could originally accommodate five people, but now it could accommodate one person to pass through. Moreover, the surrounding walls are even more full of soul crystals, densely covered with walls, and the light is shining, which makes people feel excited.

"What's going on?"

Ye Chen was surprised as he walked, and saw countless dense soul crystals along the way, like a rich soul crystal mine. But now he doesn't feel any emotion, only a very strange feeling, which is very abnormal.

"What the hell is mining in this channel, and what else is going on?" he muttered, frowning.

Judging from the excavation traces in the four directions, he concluded that it must be the work of several people, and it seems that this excavation trace is still newly excavated. However, why didn't so many soul crystals be excavated, but they just dug out a passage that could accommodate one person?

"Looks like there's a secret in there!"

Ye Chen's expression was slightly serious, and such a thought flashed in his heart, and then his figure floated and moved forward quickly. The feeling of longing in his heart grew stronger and stronger, as if there was really a voice calling and guiding him.

"It's close, it feels like it's ahead!"

As Ye Chen moved forward, the more intense the feeling in his heart became, tumbling and boiling, as if he wanted to break through the shackles of his body and sweep out. He could clearly feel that there was a strong aura in front of him, which seemed to guide him, very strange.

Bang!

Crash!

Ye Chen's expression was suddenly startled, and at this moment, a slight vibration came from the front, followed by the sound of things collapsing. His figure flashed suddenly, and the whole person merged into the void ghost qi, carefully sensing the movement in front of him, and his heart vibrated endlessly.

"Big brother, we've finally dug it through!"

At this time, a slightly excited voice came from the front, which made Ye Chen, who was hidden in the ghost qi, suddenly taken aback, only to find that there was actually someone in the tunnel ahead?
