Buzzing...... Sneer...... The faint sound of flapping wings echoed faintly in the dim tunnels.

No one noticed that the small insects were flying everywhere in the various tunnels in the mining area, and when they flew near some miners in hidden corners, especially when these miners were still alone and no one else approached within a few tens of meters around, the small insects would stop.

Then, these miners often feel tired and sleepy, and then unconsciously stop mining and fall asleep.

Soon after, the sleeping bodies of these miners would be enveloped in a cloud of silver streamers that appeared out of thin air, and then slowly turned from real to virtual, turning into wisps of streamers glittering with data codes and disappearing directly into the air.

In just one hour, more than a dozen people disappeared silently in the mine, and by the time someone noticed something was wrong and found their last location, there was only an unlost pickaxe and pieces of raw ore, and the original miners had completely disappeared.

Although many people were missing, it did not cause much reaction in the mining area, because the miners were basically scattered in groups of two or three to work in various mines, and they were not familiar with each other except for their companions in the same group.

After all, as slaves, even if they know each other well, they don't know if there will be an accident in a few days and they will never see each other again.

What's more, this kind of work in the field of mines, there is not much guarantee of safety, maybe there will be some accidents, cave collapses and attacks by wild elves, etc., it is common for one or two slaves to disappear on weekdays, and the slave miners are almost used to it, or they have become numb.

It wasn't until the sun went down and the mine was closed that the supervisors of the mine counted the number of slave miners and found that there were more than 20 people missing, and they felt that something was wrong, so they reported the result to their superiors.

After the high-level management of the mining area asked about the situation, they were not too careless, because if there were no corpses left behind and no reaction to the collapse of the mine was detected, then it was very likely that the attack of the wild elves was responsible.

Ordinary miners are not capable of fighting elves, especially such slave miners who can't eat from time to time, even if they encounter only a mortal-level elf, they don't have much ability to resist.

Knowing that there may be an elf attack on humans in the mining area, but still letting it go, he only lost a dozen coolies today, and maybe he will have to lose more slaves every day, which is a big loss for the owner of the mining area. No matter how cheap the slave miners are, they are still valuable human resources for the mining area, and they still do not have to pay salaries, so they naturally cannot be allowed to lose in vain.

As a result, the manager of the mining area sent his own guards into the mine and began to investigate the possible wounding elves.

This mining area is directly contracted by the empire, considering the safety of the mining area in the wild, the people responsible for guarding the town are all regular elves who are at least the rank of soldiers, even if the opponent is also a wild elves of the rank of soldiers, there is basically no way to make any waves in the face of the power of regular elves.

However, the results of the investigation were indeed nothing, not only did they not find the so-called wild elves that hurt people, but they also did not find any traces of corpses and struggles that the miners might have left behind, as if they had directly evaporated from the world.

Although the senior management of the mining area who did not get the results felt a little uneasy, they could not really stop the mining area for unknown reasons, which would delay the mining income too much.

So the next day, the mine was still working, but this time a few more elves and a group of heavily armed soldiers divided into groups and patrolled the various mine tunnels discreetly.

The slave miners also sensed a different atmosphere from this formation, but because of the order, they could only continue to work with their strength in anxiety.

Then, the next day, there were still people in the mining area who disappeared without leaving even their bodies, but the number was much less than yesterday, only four or five, and they were all missing in the middle of nowhere, in a remote corner and unnoticed by the patrol soldiers. The mining area is very large, and after many years of mining, the internal mine tunnels are as intricate as spider webs, and the number of soldiers who can be sent out is naturally not as luxurious as the number of miners, so it is impossible to take all the mines into account, and there will always be omissions. And where the omissions are, where the slave miners are missing, are located.

On the third day, about five or six people were still missing, and on the fourth day, four or five more were missing......

No matter how diligent the patrolling soldiers were, they could not catch the traces of the attackers in the obviously problematic tunnels, and at most they suppressed their tendency to attack the miners.

After a long time, the management of the mining area simply took a ruthless heart, abolished most of the patrol personnel in the mines, and only retained the minimum monitoring power of the major mines, and then stopped taking care of it. After all, we can't continue to waste manpower without results, because during this time, the fear of the attackers in the mine tunnel has made even the guards on the outer layer of the mine a little empty.

Even in normal times, there are an average of one or two people who have accidents in this kind of wild mining area due to various accidents every day, but now the frequency is just a little higher, since it has taken so much effort and can't find it, then simply leave it alone.

Anyway, the one who happened was just a lowly slave!

There were thousands of slaves in this mine, and every once in a while new slaves were sent over to replenish the consumption, but the loss of a few people was still bearable. That's what the top brass of the mine had in mind. It seems to be very cruel, and it is very in line with the style of the strong supremacy and the weak ants of the empire.

However, although the patrols of most of the soldiers have been abolished, a few senior patrols at the level of regular elven envoys will occasionally sneak into the mine under the instruction of high-ranking officials in the mining area, and secretly probe the attackers who may be lurking in the mine.

This kind of response shows that those high-ranking officials in the mining area are not really brainless, after all, the previous investigation was fruitless, and it was also possible that the attackers were afraid of the strength of a large number of soldiers and chose to lurk. So they took a more stealthy approach.

But the results are still in vain.

In the mining area, there are still several or even a dozen people who disappear inexplicably every day, so that the senior officials in the mining area who have always been suspicious are considering whether to ask for help from the empire, although once they ask for help, they may add disgraceful achievements to their resumes, but compared to the obvious worse outcome of the huge danger hidden in the mine but the heavy losses due to their own inaction, the senior officials still chose to act safely.

But just as he was about to make a decision, the strange disappearance of slaves in the mine suddenly stopped. Although it can't be said that there will never be an accident in the future, after all, this kind of mining work can't be guaranteed to be safe, but the strange phenomenon of making the elves who stayed behind undetectable, and the corpses have never left any traces, like evaporating out of thin air, has not happened again, and the mining area has returned to the normal situation in the past.

After hesitating for a while, he found that there were no more abnormal high-ranking officials in the mining area, and gave up his plan to ask for help, and pressed this question in his heart.

Abnormal events no longer appear, maybe the covert attacker has become disgusted with this place and left himself? The high-ranking official has reached the point where he can be transferred and promoted after another year or two, and since he has a choice, he certainly does not want to stain his political performance.

At most, it is enough to keep a private file to remind future successors.

The high-ranking official in charge of the Empire's Slar Seventh Mining District did not know that the inexplicable evaporation of the slave miners in the mine was not only in his mining area, but also in other mining areas throughout the country.

The time lasted for about half a month, and the total number of slave miners who disappeared during this period was already in the thousands.

And it's not just the mining areas, the low-level serfs who are responsible for growing food and herbs in the major planting areas outside the towns planned by the empire, as well as the worker slaves in the factories in the towns, and the female ** subordinates who are struggling in the red light district for unavoidable reasons......

The low-level slaves in various regions and all walks of life have more or less mysteriously disappeared. It's just that because the number of people is so scattered, and the timing and place of the incident often occur in a single situation where no one else notices, this phenomenon of disappearance is very inconspicuous.

After all, the country is very large, and there are all kinds of atmospheres that can easily brew the suffering of the low-level civilians, and it is really normal for someone to disappear once in a while.

What's more, the missing people are all slaves of very low value, basically belonging to the type that no one cares about even if they disappear, and there is almost no cause any waves in society before and after the disappearance......

All these factors combined, even the intelligence agencies of the empire failed to find that there was something obviously wrong in this.

......

Jiang Yan stood in a dimly lit underground cavern, his ability working silently, transferring a silver stream of data in front of him, and then skillfully transforming it from a data state to a physical state.

The silver streamer dissipated, and what appeared in front of Jiang Yan was a middle-aged man in ragged clothes and a sloppy body, with a lot of muscles on his back and arms brought by years of labor, which seemed to be quite strong, but the state of qi and blood that represented the health of the body was clearly presented under Jiang Yan's ability scanning, which was like a candle in the wind.

Although the middle-aged man had some muscles, his face was visibly thin and wrinkled with aging, his skin was yellow and rough, and even a third of his hair was gray and withered.

Obviously, what appeared in front of Jiang Yan was a person who had been malnourished for a long time, whose physical potential had also been destroyed and who had begun to die.

"Tsk...... I'm not in good health. Looking at the state of the person in front of him, Jiang Yan frowned slightly: "Forget it, I am also my future laborer, since I have the ability to do it, then I will help you improve it somewhat!"

Without him making a move, a bull-shaped elf with a huge forehead and curved horns came up next to him, and came to Jiang Yan's side and meekly lowered his majestic body.

"Luckily, I had anticipated this when I chose my target, and I had been prepared for it. Whispering, Jiang Yan raised his hand to remove the lid of the large leather bag hanging from the unicorn cow's body, and took out a small glass bottle from it, and the bottle was filled with a glowing pale green aura.

Shaking the bottle, looking at the beautifully colored potion that bumped back and forth with his movements, Jiang Yan showed a smile.

"Fortunately, after the network of the submachine is laid, I can easily collect the information of the local high-level pharmacists in this world, and I can successfully copy the herb refining related software on my body! Otherwise, there may be subtle differences in the properties of herbs in different worlds, if I just explore it myself, I don't know how much time I will waste, let alone refining potions of various attributes!"

This bottle of potion was one of the large number of recovery elixirs that Jiang Yan had spent a lot of effort refining in his spare time.

The technology has been copied through the ability, and the raw materials Jiang Yan has countless sub-machines and smart brains to help collect them, so don't worry, the key is only the output, because the only pharmacist who can be competent at present is himself, so although the output of the medicine is a lot, it is not too much.

But after today, the problem of manpower shortage in this area is no longer a problem.

"Even though this level of recovery elixir can't replenish the lifespan you've already been squeezed, it's okay to drastically improve your body's current condition. Otherwise, I'm really worried that you're going to die suddenly in the middle of work. ”

Potter, an experienced slave miner who had been working hard for seven or eight years,
