As for the medium-grade spirit stones, they are rare in this evil dragon mining area.

At this time, the mine chief hurriedly ran from a distance, this person was an innate master under Hu Longchou, but now he had surrendered, "Kitano greets the lord. Kitano hurriedly bowed his hand, extremely respectful to Ling Yun.

Ling Yun nodded and said, "I'll go take a look at this mining area." ”

"Yes, my men will go down with you. Kitano nodded, and took the lead in front and walked forward with Ling Yun.

"Okay!" The group slowly descended, and finally saw the mine, which was a horizontal passage dug under the ground, and at least a third of the slaves were now mining spirit stone mines in the mine.

"Kitano, how many spirit stones can be mined in the mine every day?" Ling Yun asked, turning his head.

Looking at the pitch-black mine in front of him, Ling Yun also frowned, although he had been wandering and fighting for several years, he had never entered this dark and damp, and pitch-black mine.

Kitano hurriedly said: "The number of daily is not fixed, but 30,000 spirit stones in a year should be about the same, but now the environment in the mine is getting worse and worse, and in the last month, dozens of slaves have died in the mine." ”

"What's going on?" Ling Yun was surprised for a while, and hurriedly asked, Ling Yun had not entered the spirit stone mining area before, so he was a little puzzled.

"With the continuous mining, most of the places that can produce spirit stone mines are close to the sand layer, and it is likely to collapse during the mining process, and many slaves will die in it, but the most dangerous are some underground demonic beasts hidden in the mines!"

Kitano led everyone into the mine, which was now only the very edge of the mine, and the walls of the cave were all hard rock, so there would be no danger.

"Underground Demonic Beasts?" Ling Yun looked at Kitano suspiciously.

Kitano nodded, and then explained: "Yes, this underground demonic beast is also divided into two kinds, one is some earthly beasts that live in the rock layer and sand, some are large and some are small, and the attack methods are completely different, there are swarm-living gravel ants, there are also lone rock snakes, Kui demons, etc., and the other lives in the water, of course, they can also impact people on the road."

"Because of the uneven distribution of Lingshi mines in the mining area, the current mine cave has become extensive, intricate, if there is no one to lead it, it is even very likely to get lost in the mine.

"And as we continue to dig down, we found a huge underground lake, in this underground lake there are a lot of water monsters, strange and unpredictable, and generally very huge, and the means of attack are also extremely ruthless, so the most dangerous thing in the mine is this water monster. ”

Ling Yun was surprised for a while after hearing this, if he hadn't come here by himself, he really didn't know that there were so many secrets in the mine.

As they slowly moved forward, everyone had come to the depths of the mine, where there were torches, oil lamps and other lighting facilities, but because the passage was in all directions, most of the places were not too bright.

Especially around the corners, this kind of place is the most vulnerable to the attack of underground monsters.

Shan Haizi and the natural disaster are also frowning, but the natural disaster still has a trace of expectations for this environment, if it can devour some underground demonic beasts, and then complete the decomposition of their life structure and ontological genes, maybe they can also create a group of weird underground killers.

However, thinking about it, this underground demonic beast should not be easy to parse, and the number of most underground demonic beasts is not too much.

Shan Haizi always followed Ling Yun's side, and many civilians next to him walked towards the outside of the mine with stones on their backs, and some civilians also entered the mine.

After another incense stick, Ling Yun finally saw the slaves who were mining spirit stones, these slaves were almost bloodless because they lived underground all year round, and their upper bodies were almost without clothes.

Although the inside of the mine was a little cold, it didn't feel cold for people like them who were desperately mining ore, but sweated profusely.

These slaves have different identities, many of them were originally sold here as slaves, some were captured by Hu Longyu from all directions, and some were captured on the battlefield, and they were directly reduced to slaves and thrown into this mine.

There is almost no light in their lives, and whoever reoccupies this mining area is the lowest slave in the mining area, and they can only desperately mine the spirit stone mine.

However, not everyone is without opportunities.

As long as someone mines ten low-grade spirit stones, they have the opportunity to be promoted, and they can become the captain of the slaves, and the captain can not work, as long as he takes good care of the other slaves.

And the slaves under his guardianship can mine a hundred low-grade heavenly stones or a medium-grade spirit stone, and they can become centurions, have the right to leave the mining area, and even have a certain salary, and can also marry some ordinary girls in the town or in the surrounding villages.

This was their only chance, but it was not easy to mine ten lower-grade spirit stones, after all, more than 20,000 slaves could only mine 30,000 lower-grade spirit stones a year.

Ordinary people are afraid that it will take about ten years to become the captain and manage fifty slaves, but they are still working hard because this is their only chance.

Kitano told Lingyun about the rules in the mine.

Ling Yun understood that the exploitation of these slaves was also a helpless move, because if all the civilians were overrecruited to mine the spirit stones in this kind of place, I am afraid that even the cost would not be enough.

Moreover, in the world of slavery, slaves themselves are the lowest class of beings.

There were dozens of forks in the road, and each fork in the road extended to the depths of the ground, and there were many forks in it, if no one led it, Ling Yun and the others could really get lost in it when they entered this evil dragon mining area.

"My lord, are we going to move on?" Kitano thought that Ling Yun was just here to take a look, so he turned his head to look at Ling Yun and asked.

Ling Yun nodded and said, "Continue to lead the way, I want to see the entire mining area." After saying that, under the leadership of Kitano, everyone continued to move forward, and the number of slaves here had begun to increase.

Although the possibility of spirit stones appearing in many places next to it is extremely low, in order to mine spirit stones more safely and efficiently, Kitano ordered those slaves to continue mining from the cave wall next to it.

Mining ore requires a lot of tools and equipment, and some even require dozens of slaves to work together to break through a boulder underground, so it's a dangerous and heavy job, and almost every slave is working in pain.
