Karel gripped his dagger and cautiously walked into the mine, which was completely dark, but not a problem for Karel with night vision goggles.

Because it was a reconnaissance activity, all Karel walked very slowly, and tried to gather as much information as possible to see what was going on here.

Walking through the twists and turns of the mine, Karel noticed that there were more or less strange scratches on the surrounding rock walls, well, maybe not quite right to describe them as scratches, the scratches could not have been so smooth, as if they had been corroded.

Karel deduced it in his mind and came to the conclusion that the creature with a highly corrosive liquid in its body fluids was walking in the mine, and the epidermis was broken by the mine wall, and the liquid in the body rubbed against the mine, so that this kind of long strip of corrosion marks appeared.

Karel picked up some long strips of stone from the ground, and buckled them in the corrosion marks, easily seizing a large piece of stone dust.

The entire stone wall has been corroded and crisped away.

Throwing away the stone in his hand, Karel continued to walk deeper into the mine, where he could not see anything by tapping the stone through the crack in the doorway.

The entrance to the mine is very long, about 50 meters before you really enter the mining area, from the angle and length, it should be already underground at this time.

In front of Karel, there are three forks in the road, each leading in one direction, and it is not certain whether there is a crossing behind it.

Through the night vision goggles, Karel saw a torch stuck in the fork on the right, so Karel walked over, for which it was impossible to light it. Once lit, the entire mine monsters will be attracted, and Karel will just see if the torch has been lit recently.

Taking off his gloves, Karel twisted a little dust from the torch, then rubbed his two fingers together, and felt that as expected, the dust was dry and should have been lit within 10 days, so the young man that the militia captain said should be the right road.

Rubbing his fingers clean against the wall, Karel put his gloves back on. Then head to the road on the right.

After a short tunnel. Karel came to an unusually open mining area with a lot of tools scattered around, but surprisingly, there weren't any monsters here. And it's quiet all the way. There are no monsters in sight. Not even a sound.

As an elf, you can't go wrong when it comes to hearing.

"What about the undead monsters? Where have they gone? "Originally, it was expected that this place would be similar to an ant's nest. It's densely packed with undead, and then an unknown being is constantly producing undead, as long as that source is killed, the crisis in Romi Town will be directly resolved, but now it seems that something is wrong.

The situation was unexpected.

At this moment, Karel saw a few small glowing white dots in the mine, although it was a bit inappropriate to do something extra in such a dangerous place, Karel couldn't help but be curious, and walked over to take a look.

Actually, there is nothing unusual, just a few glowing fluorites, but the problem is that with the faint light of this fluorite, Karel can see what kind of ore is produced in this mine.

The ore is black, semi-metallic, and plate-like, with uneven fractures and hard and brittle physical properties, and Karel clicks a small piece down.

"It's kind of familiar." Looking at the ore in his hand, Karel fell into deep thought, it was clear that this must be some kind of metal ore, which may contain a small amount of iron, so it looks like inferior iron ore, but its essence is not this.

"Isn't this tungsten?" Suddenly, Karel had a flash of inspiration, remembering that when the fortress was first established, a group of people were looking for minerals all over the mountains, and along the way, they heard Dwarf Gasla chattering over there, saying that most of them were tungsten, but unfortunately they had been looking for more than half a month, not to mention the ore veins, and few ore had been found.

Thinking of this, Karel really admired the blacksmith in Romi Town, who was able to melt the iron in the tungsten ore separately and make it into a tool, which is really amazing.

Throwing away the ore block in his hand, Karel got up and continued to investigate, there must be something here, but he didn't find it.

After wandering around for a long time, I really found something for Karel, and there was a footprint on the ground.

Although this is a mine, there are places where it is not hard rock, but relatively soft sand, that is, crushed ore powder, and on a gravel floor against the wall, Karel saw a footprint two or three times larger than himself.

After eating the Luna Fruit, most of his body became much smaller, including his feet, so this anomaly was easily visible to Karel.

As for why there is an abnormality, the reason is very simple, from the stress state of the footprints, the front is deep and the back is shallow, it is obvious that this person was running at the time, and the heel of this footprint is facing the wall, and this is not a platform of nine and three-quarters, people can't run out of the wall, so if you put these together, it means that this wall originally did not exist.

So why are there rock walls here that shouldn't be there?

Karel was puzzled.

But this is clearly an anomaly, so it caught Karel's attention.

After groping around the wall for a long time, Karel found that it was not a complete wall, but a large number of stones piled up, needless to say, it must have been man-made, and it would never have been possible to collapse such a neat plane if it had collapsed naturally.

Therefore, this road is not possible to cross at this time, unless it is fried. medicine, but this can easily collapse the entire mine together, and it can't be scratched.

Thinking of this, Karel retreated, and then walked towards the intersection, there are 3 intersections in total, and now he has only explored one, so there is no hurry.

Retreating to the fork in the road, Karel chose the middle hole to explore this time, as before, this place is also quiet, but the mine is full of messy marks, footprints, scratches, friction, traces of corrosion, everywhere as if this place has only been held before, the middle passage is very long and deep, like a sugar gourd, the two mining areas are connected by a tunnel, mining tools and other things are scattered all over the place, but there is not a single undead, very, very quiet.

"Hell, why isn't there anything?" Karel muttered at the strange sight before him, then took off his engineering glasses and wiped off a light stick.

With a hissing sound, a red light illuminated the mine, and Karel held a light rod to look closely through the mine, from the deepest to the outermost part, and unfortunately, there was nothing but the messy scratches.

Karel dropped the light stick, put on his engineering eyes, turned on the night vision goggles, and walked to the last passage, and if he still couldn't find anything in the last passage, then he had to test the thickness of the wall with explosives.

"Hmm, it smells rancid." Walking in the leftmost passage, this passage is more shaky, and it keeps going down, in this world where space backpacks are flooded, the mine cave does not need to be very smooth, dozens of tons of ore are packed into cheap space backpacks, and even a small child can run around with it.

Walking in this passage, just a few dozen meters deeper, a strong sour smell rushed straight to the brain, making people sick to their stomachs. Looks like you're going to find something here.

After rummaging through his backpack for a long time, but he couldn't find anything that could stop the disgusting smell, Karel had no choice but to endure it, hoping that he wouldn't vomit.

The leftmost passage leads to the underground in a spiral shape, and there is a disc-shaped mine every 10 meters or so at vertical distances, and the smell gets stronger as Karel goes down, and finally, in the third mine, Karel finds the source of this smell.

A puddle of green water, in the far middle of the third mining area, was a puddle of eerie green liquid that emitted a fluorescent and disgusting smell.

Holding back the disgusting smell, Karel walked in to observe, and at that moment, the ground exploded at his feet!

Three strange-looking creatures emerged from the dirt and let out a gurgling roar, and because they couldn't see Karel in a stealthy state, the three guys looked confused, screaming and spun around.

The iguanamen, though they had turned into disgusting walking corpses, still recognized at a glance what the creature was.

The Iguanamen, a creature that feeds mainly on ore, have short and stout limbs, a large mouth that can grin to the root of the ear, hard and sharp teeth, and a gland in the mouth that secretes a corrosive acid, enough to melt any ore, the Iguana frequently haunts various mines, and in the mine in the fortress, several iguana corpses are dragged out almost every day.

The iguana man has 3 stomachs, all of which are used to digest ore, from the third stomach of the iguana, that is, the stomach closest to the intestines, you can find metals of almost 100% purity, and the fortress has not yet found a way to smelt titanium ore, but all the titanium metal on hand is taken out of the stomach of the iguana.

The iguanas in front of them are very similar to the children they saw when they first arrived in Romi Town, their eyes are gone, they have turned into some writhing tentacles, their mouths are split into three petals, and their bite has been enhanced, but unlike humans, these iguanas have many green pustules on their bodies, and some of them are still trembling, looking very unstable.

So now there is a question, is it because this pool of green water leads the people of zhì iguana people to become undead or because of the iguana people who have become undead to make this pool of green water?

Either way, there must be a problem with both the iguana and the green water.

Thinking of this, Karel pulled out the M500 Hand Cannon from his lap and installed the silent enchanted version at the same time.

When dealing with things that will explode on their own, it is best to explode them far away. (To be continued......)
