Under the gray sky, the mountains are undulating and endless, and in a dense mountain forest, there are many figures.

"Hurry up!

The sound of scolding was faintly heard, and it was a group of underworld races with various appearances driving a group of people into a dark hole.

The entrance of the cave is only one zhang in size, but it is bottomless, and rows of miners enter it one after another, and the mine seems to be able to accommodate hundreds of rivers, all of which will swallow people.

The two tiger-headed men said, "The condition has been getting better and better in recent times, and after four years of hard work, I finally dug up to be able to use it, alas, it's really not easy." ”

"Who said no, in the first two years, the dug up color was not good at all, but I didn't dare to sell it to the outside world, so I could only treat it as a few years of vain, and now it's finally about to be harvested. ”

Two tiger-headed men were chatting in front of the cave, not noticing that a strange ox-faced man had also mixed in with the team.

The pitch-black underground cave leads straight to the ground, and the power of Gu Chen's soul unfolds, and he can only feel the intricate mine path spreading far away, but he can't find out how deep it is, as if it goes straight to the ground.

As Gu Chen continued to go deeper, finally, one fork in the road appeared, leading to different directions, and the crowd also dispersed at this time, walking to different passages.

Looking at the several forks that suddenly appeared in front of him, Gu Chen couldn't help but wrinkle his forehead, which passage to take?

Just as Gu Chen was hesitating, there was a sudden sound of wind behind him, and he was about to make a move, but in the end, he gave up, allowing a heavy big hand to suddenly slap his shoulder.

"Brother, just came, didn't you?"

Gu Chen turned around, he was also a bull-faced person, but he was burly and looked very thick.

Gu Chen nodded, "That's right, my name is Niu Er, I just came, and I don't know where to go at this time." ”

"Hahaha, follow me. The cow-faced man patted his chest and said, "My name is Niu Qi, and I've been working here for three years, let's go, everyone is from the same clan, I'll take you with me." ”

Niu Qi was very hearty, and after that, he strode directly to the passage on the far right, Gu Chen did not hesitate, and followed directly.

The pitch-black passage did not have any light, and he couldn't even see his fingers, of course, it was naturally not a matter for Gu Chen, but Niu Qi walked steadily in front of him, and he did look extremely familiar with this place.

Erniu's voice suddenly sounded in Gu Chen's mind, "Gu Chen, I'll eat him, so I don't have a clue." ”

"Nope. Gu Chen said, "Although this person is an underworld, he is very hearty and not bad-hearted, if such a person is killed, we will be a little too much." ”

"Hehe, casually, in fact, there is nothing to explore in this place, as long as you find the blood marrow vein, it is enough to get more. ”

Gu Chen nodded and continued to follow Niu Qi forward.

Suddenly, Niu Qi said, "Niu Er, how long have you been here?"

Gu Chen was stunned for a moment and said, "I just came here today." ”

"You just came here today, and you went to the mine on the first day, didn't anyone teach you some knowledge about the mine?"

"Mine knowledge?"

"Yes, this underground is not as good as the ground, sometimes you will encounter some very dangerous things underground, and you will die if you are not careful, so you have to learn some common sense to save your life in the mine, hey, Heimen is becoming more and more irresponsible now, and he didn't teach you to let you go to the mine, if you encounter danger, then it will be troublesome. ”

Gu Chen inadvertently wrinkled his forehead: "Brother Niu Qi, could it be that under this mine, what is the danger of death?"

"It's more, but you don't have to be afraid, you will follow me in the future, if you really encounter any danger, I will cover you, let's go, it's still deep below, we must return before dark, this is not the time to go up and down, the time to really mine, it's only two hours, if you don't hurry up, I'm afraid I won't be able to harvest anything today." ”

The speaker had no intention, the listener had a heart, Gu Chen subconsciously said, "Brother Niu Qi, why should we go up before dark, do we have to clean up people in the mine after dark?"

"Hey, of course not, what, haven't you heard the rumors of the Blood Marrow Mine?"

"What rumors?"

"The blood marrow mine is the blood of the earth, we are digging the blood marrow mine now, it is like sucking the blood of the earth, during the day when the earth is sleeping, it is naturally unharmed, but once it is night, when the earth wakes up, if he finds out who is sucking his blood, then he will not kill him. ”

Although it was a rumor, Gu Chen also heard it, once at night, everyone who stayed in the mine would die, but Niu Qi didn't know what the specific reason was.

Thinking of this, Gu Chen sent a message to Er Niu and said, "Er Niu, do you know what is going on with this kind of rumor about the Blood Marrow Mine?"

"It's hard to say for a while, because there are indeed some strange things underground, but they can all be explained, either mountain spirits, or souls that do not disperse after death, and some other underground species are haunting, but I prefer the last one. ”

"Which one?"

"It does not belong to the mountain spirits, nor to the souls that do not disperse after death in this underground, nor to the underground species. ”

"What's that?"

"Mineral spirits. ”

Minerals?

Gu Chen was stunned for a moment, and subconsciously said, "What is the mineral essence?"

"This is a kind of ore vein life that can only be born in a large ore vein, like a guardian, protecting the entire ore vein, and the ore essence does only appear after dark, if we can find the ore essence, then this time it will really make a lot of money, there are ore veins with ore essence, there must be ore source stone, and the ore source stone does not know how many times higher than those ordinary ores!"

Gu Chen nodded understandingly, he didn't expect that this random piece of news would have such an unexpected extension, and he couldn't help but look forward to it at the moment, if everything was really as Erniu said, then this would be good for his second doppelganger.

Niu Qi is a hearty person and is also very good at talking, and constantly asks Gu Chen about some things about the outside world along the way, and Gu Chen also prevaricates, and after some exchanges, he understands a lot about him.

Niu Qi was caught in the Black Gate three years ago, and at that time he was still thinking about how to escape for his life, but because the Black Gate's security was too tight, after several times to no avail, he settled down.

Because the treatment of the Black Gate is very tempting!

In fact, not only in the underworld, but even in the human world, miners exist, and in much the same, the work is hard and the pay is very low, which can be said to be a helpless choice for desperate people to make a living.

But the treatment of the Black Gate is different, the treatment of the Black Gate is very high, not to mention that there are only about two hours of mining time every day, I am not tired at all, and the food and drink are also extremely rich, as long as you can eat, all kinds of wine and meat are enough.

Not only that, but Black Gate will also arrange women on a regular basis, and a woman who has agreed in advance what race you want will be arranged to your side in a maximum of three days.

In addition to the need to work in the mines, it is completely the general treatment of the master, and Niu Qi chose to stay steadfastly because of this generous treatment, not only him, but also 90% of the people.

Temptation can make a person stay willingly, and no matter how strict the control is, as long as there are more people who escape, they can always escape.

This method of the Black Gate, Gu Chen is quite admired, although the power is not large, but the person who leads the Black Gate is a person with means, over time, the growth of the Black Gate will inevitably be unlimited.

As Niu Qi said, the mine is very deep, and as it goes deeper, the temperature around it also gets higher and higher.

Niu Qi said, "Niu Er, you be careful, from here on, the temperature below will be higher and higher, if you can't support it, you must tell me in advance, in the past three years, there are many people who just didn't take this high temperature seriously, and as a result, they fainted from heat stroke, and they never got up again." ”

Gu Chen nodded, "Thank you Brother Niu Qi for reminding us, but how long do we have to get there?"

The temperature was not a threat to Gu Chen, but he was still very grateful to Niu Qi for his reminder.

"Immediately, hehe, this place is a small road that I dug alone, it is rich in blood marrow minerals, seeing that we are brothers of the same clan, this is the first time I have brought outsiders here, come and go here. ”

A hidden gap appeared, Niu Qi was in front, and he took the lead in walking in, and only after Gu Chen went in did he find that there was a hole behind this gap, which was very spacious, and he couldn't help but say, "Brother Niu Qi, you didn't dig this place, did you?"

"Hehe, you've found out. Niu Qi smiled and said, "Actually, I discovered this crack by accident, and after a little exploration, I found that the blood marrow ore content in it is much richer than the ore veins outside, help me keep this secret, I have never brought anyone else here." ”

A faint smell of blood began to appear, Gu Chen couldn't help but nodded, and finally, after the two of them continued to go deeper, the smell of blood became even stronger, and the two of them also stopped.

Niu Qi lit an oil lamp, and Gu Chen realized that in front of him was a stone that seemed to be stained with blood, but it exuded a strange power.

Niu Qi said, "Look, this is the blood marrow mine I found, the content is much higher than the outside, there is no need to work hard at all, we only need to knock down two pieces, and we can make a difference." ”

Niu Qi said with a smug face, but Gu Chen's eyes narrowed slightly, his blood-red eyes swept from the ground and the stone walls on both sides, and he couldn't help but say, "Brother Niu Qi, how long have you been digging here?"

"Well, it's been almost three months. ”

Trimester?

Gu Chen walked slowly to the rock wall, his fingers stroked from a faint trace, and said, "It seems that Brother Niu Qi is still here, and it is really fateful." ”

Niu Qi was stunned for a moment, "What do you mean?"

"There's a thing in here, look at the traces on the rock wall, the earliest traces are already a month ago, that is, you have been together for nearly a month, but it didn't kill you. ”

"What?" Niu Qi's eyes widened, his expression incredulous.
