My Skills Have Special Effects

Lin Yan took out the cloth map and carefully compared the surrounding environment.

On this map, the area on the lower left is clearly consistent with the valley in front of you, and the red point marked on it is at the upper right of the map, and there is a curve that is probably a river, reaching the red point.

"So, first find the river in the valley and walk along the river to reach the red dot mark."

Lin Yan's physical fitness was greatly improved at this time, and his hearing was also extremely strong. He soon found a stream in the jungle-covered valley.

The stream is at most an arm's length wide, actually has an orange-red color, exudes a pungent smell of sulfur, and winds its way deeper into the valley.

Lin Yan moved forward along the stream, gradually going down the hillside, and going deeper into the valley. The plants along the way became darker and greener, with many plants similar to banana trees growing. The air became more and more humid, and water could come out with a touch.

Soon, we arrived at the bottom of the valley, a narrow cave entrance three people high and one person wide.

The stream flowed rapidly inward along the entrance of the cave, making a faint sound of water, and submerged into a gloomy darkness, as if being swallowed by a cracked mouth.

"I didn't expect it to be a cave. This is the place marked by the red dot. The stream continues to flow in, but it does not fill the cave. There must be a cave inside."

The mouth of the cave is a golden rock mouth. The rock walls inside are smooth and moist, with some gray moss growing on them. Further inside is a dark cave with nothing visible.

Lin Yan searched around and found that the surrounding trees were all wet. He had no choice but to climb up the valley slope again, found a thick dead tree, made a torch, and then came back to the cave.

Inside the cave, a thin and hazy white mist emerged. Below was a stream, and the left and right rock walls were polished smooth by the water flow.

Lin Yan didn't want to step into the water, so he directly formed a claw with one hand, grabbed it on the rock wall, and entered sideways.

The skylight fell behind him, and the environment suddenly turned south. Lin Yan raised the torch forward. The cave in front of him was extremely deep and winding, and the dark firelight could not illuminate it completely.

Climbing quickly along the rock wall, the darkness becomes thicker as we go deeper, and the rock walls on the left and right, up and down, open up, making the internal space wider.

"There are some traces of excavation here, like some abandoned mine."

There must be some mineral components nearby, especially the smell of sulfur is stronger.

There was the sound of a waterfall crashing down the rock wall, and Lin Yan soon came to a large crack in the ground.

The stream forms a waterfall here.

It does not go down in a straight line, but goes down one or two feet, accumulating a turbid and yellowish pool, and then continues to overflow from the edge downwards, winding and twisting, until it goes deep into the depths of the ground.

"The surface of the nearby rock is as smooth as the rock wall just now, which means that the crack has existed for a long time and was not caused by a recent earthquake."

The waterfall was winding and flowing. When Lin Yan was illuminated by the fire, he jumped directly across several feet of darkness and jumped to the rock wall opposite the pool below. He inserted one hand into the rock wall and hung himself firmly.

There was a black, bottomless abyss underneath. Wet water drops gathered along the rock wall and onto his hands, and there was only a small patch of firelight.

At this time, Lin Yan looked to the left side of the rock wall and saw a thick and long iron nail driven into the rock wall there.

“There’s not a lot of rust, it was nailed in recently.”

Naturally, he didn't need nails to make a ladder, he just followed the law and jumped down again, to the rock wall opposite the pool further down.

Just like that, he jumped down and kept going down the rock wall.

Along the way, waterfalls merged into streams again, and in some areas, a large area of ​​jagged cobblestones was exposed, and he walked on it.

Going down like this, I don't know how deep I went down. I just felt that the surroundings were extremely hot and stuffy, and I heard a rumbling sound of water.

"There's a big pool underneath this sound!"

Lin Yan walked forward, and an underground rift appeared in front of him again. It turned out to be an underground cliff!

The water poured down along the cliff, falling into the unknown depth of darkness, making a roaring sound.

"Aren't these blood stalactites on top? This depth is already deeper than the depth of the underground black market in Ding'an City!"

Lin Yan found the smooth rock wall on the side of the waterfall, held the torch in his mouth, and used his hands and feet to climb directly down the smooth rock wall.

The rock wall shows a translucent white jade color, which should be some kind of special mineral. It has been polished extremely smooth by the erosion of water, and it can almost reflect the human figure.

Iron nails were driven into it at regular intervals.

The weak firelight flipped up and down, and Lin Yan was obviously moving, but he still had the illusion of stagnation, as if he was moving in place in an endless darkness, following a mirror that could never reach the bottom.

Fortunately, this rock wall has a bottom. After climbing for a long time, Lin Yan clearly felt that the water vapor below had increased significantly.

Taking off the torch and shining it, his eyes narrowed slightly: "What a big pool!"

Under the rock wall, there is actually a pool with a radius of more than ten feet, showing an amber-like green color, and there seems to be a vortex in it.

In the center of the pool, there is a huge black rock standing in it.

Amidst the roaring sound of the water, Lin Yan swept the torch and realized that the underground space was surprisingly large. There was also a rugged rocky land covered with square cobblestones beside the pool.

He turned around so that he was standing on the rock wall. His feet suddenly exerted force, and he was ejected like a slingshot, landing in the open space beside the pool.

The torch swept left and right, and a silver dragon-like waterfall poured down from above and landed in the middle of the pool, with a deafening roar.

But the water surface of this pool did not rise at all. It seems that there is a deeper seepage channel under it, and all the water flow gathers here and is swallowed up silently.

There was a hint of shock in his eyes. Who could have imagined that in such a deep underground world, there was actually a silver waterfall flowing down three thousand feet!

suddenly.

Lin Yan frowned.

He slowly approached the water pool, and the torch carefully shone on the water pool.

In the dark underwater depths, there was a huge black shadow lying quietly!

Its appearance looks like some kind of fish, but its body is about the size of two adults. It lies quietly in the deep water without moving.

Lin Yan held his breath, picked up a stone from the ground, used his wrist strength, and threw it into the water!

boom!

A dull sound came.

The water waves suddenly became chaotic, as if there were creatures rolling and moving beneath them.

When the water surface calmed down again, Lin Yan took a torch to see, and the black shadow had disappeared!

Only the dark, deep layer of water remained.

"It's really alive! Is there such a huge fish in this underground pool?"

This pool obviously cannot support such a big fish. It seems that this pool leads to a larger and deeper river.

"Huh? What is this?"

On the surface of the water, a black shadow half the size of a palm appeared, floating on the water and spinning continuously along the current.

Lin Yan lowered the torch, raised his eyebrows slightly, and saw another fish!

No, it's half one. It looks very fierce, like a carnivorous species, but the whole body seems to have been soaked in acid and corroded by more than half, leaving only the most mutilated body.

"These teeth look really weird..."

Its teeth protrude, two on each upper and lower jaws, but they are all in the shape of curved hooks. The tips stick together, but the center cannot be closed, like a ring. If you put a person's finger in it, no matter how hard it bites, it will bite. Can't even bite it.

suddenly!

Lin Yan tightened his wrist slightly, and the eyes of this strange fish moved!

It only had one fierce fish eye, which seemed to sense the fire and actually stared at the fire part!

"You're still alive after all this?"

But the strange fish suddenly opened its upper and lower jaws at a weird angle of 180 degrees. It swung its tail vigorously, opened and closed its bite wildly, and swam in the direction of Lin Yan's fire!

"This vitality is so tenacious! This ferocious temperament is definitely that of a piranha!"

The body of the strange fish was originally mutilated. With the huge range of movements, liquid and internal organs could be seen oozing out of the body. However, it actually swam to the edge of the pool with such a mutilated body, and then...

He fluttered among the rugged cobblestones, dying and motionless, killing himself.

Lin Yan took a torch and shined it at him. His eyes were dark, and he was completely dead this time.

But the strange thing is that its blood is actually green, which is somewhat similar to the green pus blood of the corpse cockroach.

"Are the creatures in the underground water so weird..."

With one step, Lin Yan turned around and continued exploring.

In the cave after the water pool, the color of the rock walls is obviously different, with black and yellow intertwined, like a spider web pattern. It is a rock formation that can only be seen in extremely deep strata.

"There is actually an oil lamp nailed to the rock wall. There is only a little rust on the oil lamp, and the oil inside has not completely evaporated, which means it hasn't been long. It seems that someone has been here before me."

Lin Yan raised the torch and lit the oil lamps on the rock walls one by one. The entire dark tunnel immediately became much brighter.

"I didn't see it just now. There are actually footprints and drag marks in the mud on the ground. It looks a bit blurry. It means that someone was working here before, dragging something."

Lin Yan continued inward along the tunnel, but after walking around, it turned out to be a blind road, a dead end.

"Impossible. The dragging tool ropes can't be left behind, right?"

Lin Yan turned around and searched carefully inch by inch along the way.

"here!"

I saw a pile of huge black and yellow rocks scattered on the ground in a corner near the center of the blind path.

"These rocks are not here naturally, but were piled up later."

If Lin Yan hadn't looked carefully and saw a crack as thick as an arm underneath, breathing out wind, he would not have realized that there was a cave entrance under the pile of boulders.

The rock was huge, so Lin Yan moved several smaller ones around it, but the central one was huge and terribly heavy. It was probably weighing dozens of tons, and even he couldn't shake it.

Helpless, he directly exerted his strength and grasped the stone with his hands, as if grasping dough, claw by claw from the stone.

Of course, he could break it with one punch, but in this case, the broken and scattered stones would most likely fall into the entrance of the cave below and block the entrance.

The firelight flickered, revealing his silhouette as he worked hard digging rocks.

Soon, a lot of gravel was scattered around him. Only a thin layer weighing about a thousand kilograms of this huge stone was left. He lifted it with both hands and flipped it aside.

"Huh? This is..."

Lin Yan's eyes narrowed slightly. The lower part of the stone was actually covered with bloody scratches, criss-crossing it, and human fingernails could be seen embedded in the stone, which showed the despair of its owner!

"Is anyone trapped down there?"

Looking down, there is an abyss gap extending vertically downwards below the cave. The entrance is only the size of a person, and the downward gap is also extremely narrow and bottomless.

Lin Yan was secretly vigilant, following the entrance of the abyss gap and climbing down the rock wall.

The crack is extremely narrow, only large enough for one person to climb down. The chest and back are pressed against the rock wall, which saves effort.

There were many iron nails driven into the rock wall and many ropes hung there, showing obvious signs of someone climbing.

Thinking of the scratches all over just now, is there really someone down there?

Compared with the above, the rock wall here is obviously much rougher, and the traces of fault separation are obvious. The cracking time will definitely not exceed half a year.

After descending another thirty or forty meters, the surrounding space suddenly opened up.

Moreover, a thin layer of blue light appeared from nowhere, coating the surrounding rock formations with a mysterious light.

"This is...the light of the Netherworld River!"

But the depth he has descended to now has already exceeded the depth of the underground black market in Ding'an City. In other words, the height of the Netherworld River should be at least two to three hundred meters above him!

How come it appears here?

Lin Yan grabbed the rock wall and climbed down quickly.

The surrounding space is getting bigger and bigger, like an inverted funnel. The further down you go, the more open the space becomes.

Finally, the rock walls in front and behind suddenly became clear, and Lin Yan's eyes narrowed slightly. A blue and mysterious underground river, exuding a rich light, flowed through the underground cavity below!

This cavity has a huge area, surrounded by blue-gray rock walls with rugged twists and turns. There is also a huge open space by the river, covered with rugged and huge rocks.

Stepping on the stubborn stone, Lin Yan slowed down his breathing slightly. It was really the Netherworld River!

What secrets are hidden in the underground space of this world?

What's going on with this Netherworld River?

It's like appearing and disappearing, and there are actually them at different heights? !

There was enough light, and Lin Yan's field of vision was broadened.

He walked to a flat open space by the Netherworld River. The stones were moved away to enclose a cavity area, with several tents set up in the middle, as well as pots, pans and other traces of human existence.

On the left side of the camp, several baskets were neatly placed, containing some gray and black stones. Lin Yan walked over, picked them up and looked at them. They were just ordinary scraps, nothing special.

But there was only one missing figure.

Lin Yan originally thought that someone was trapped under the crack in the ground, trying to push away the boulder blocking the passage, but couldn't get out, so the criss-crossing blood marks were left.

There were also many tragic situations that popped up in his mind, such as a group of people trapped in a dark underground with no food, and in the end they could only compete with each other and feed on each other... and so on.

But after checking the surroundings, everything was perfectly preserved, and there were no signs of fighting, struggle or blood stains.

Everything was peaceful except for the lack of people.

Did this group of people go somewhere else?

Lin Yan looked back at the other end of the river, which looked like a horizontal tunnel leading to an unknown place.

But if there is another way out, why are there such desperate scratches under the boulder?

Lin Yan couldn't think clearly for a moment, so he raised the torch and walked up the river step by step.
