A shrill whistling, filled with an evil aura...

Ling Feng clenched the bronze javelin and walked forward vigilantly.

It was pitch black ahead, and if it wasn't for the glowing stone, it would have to be dark.

Even though the Dark Eye Gate could allow him to see farther, it would take too much effort.

The passage is wide enough for five people to walk side by side, and there are lamps arranged on both sides, not modern wall lamps, nor like ancient oil lamps.

Ling Feng took one from the rock wall, it was obviously a bronze lamp, the surface of which had been covered with a layer of black lacquer.

As for the fuel, it is already impossible to discern, and even the smell has disappeared.

There is only the smell of decay.

Ling Feng put the lantern back in its place and continued to look around as he walked.

I walked for a long time, but I didn't find anything else except the lamp.

Ling Feng looked up and down, there were also lamps hanging on it, and there were two deep ruts on the ground, and he couldn't see the direction of the ruts.

Judging by the depth of the ruts, it must have been a heavy baggage cart, but I don't know what heavy things are going to pass underground.

Suddenly, Ling Feng seemed to feel that he had overlooked something, so he looked at the rock wall.

I saw that this rock wall was like the Taigu Tongling, and it was all black and ancient Tai Sui.

The only difference is that there is no blood Tai Sui in this.

Moreover, the black ancient Tai Sui here is obviously older than the one at the entrance of the Taigu Tongling.

It's kind of like a fossil, but it's not a fossil by its texture.

If there is a dark shadow passing by, there may still be a glimmer of life.

After walking a little further, suddenly the passage became wider

Immediately, a bronze door with a patina was found on the side of the rock wall.

The bronze lock on the door was rotten.

Ling Feng didn't use much force, and ripped off the bronze lock.

Immediately, Ling Feng pushed open the bronze door...

A smell of decay rushed towards him, but fortunately, Ling Feng was prepared and hurriedly moved sideways.

After a while, the smell faded a lot, and Ling Feng stood at the door again, holding the glowing stone and walking in vigilantly.

It was a cell, with rusty chains on the walls at intervals, and shackles on top of the chains.

Needless to say, this must have been the place where the ancestors were imprisoned.

In this dark and harsh environment, no one will feel good here.

Ling Feng scrutinized it along the wall...

Suddenly, some stains on the walls caught his attention.

On the pitch-black wall, there was a layer of upturned wall skin, Ling Feng tore off a small piece, and when he looked closely, it was not the wall skin, but blood stains!

Not only here, but also on the walls that are almost chained and shackled, there are such blood stains.

Ling Feng couldn't help but clench his fists, there was no need to think about it, these blood stains must have been left by the ancestors when they were sad and angry.

One can imagine how miserable and desperate they are here.

Or, the evil scream when they first came in was their condensed grief and indignation!

Out of this cell, Ling Feng walked a few steps forward, it was another cell, and the situation inside was the same...

Further on, Ling Feng saw countless prison cells, all of which were places where the ancestors were held.

It's hard to imagine that it was a purgatory-like existence at the time.

Even though Ling Feng's heart was already firm, seeing such a scene was also touched!

When he passed through these cells again, Ling Feng did not inspect them one by one.

After a long walk, the cells finally came to an end.

These cells are only a part of the prison cell, and thousands of people are being held, which is a huge size!

Walking through this passage, there is no fork in the road.

Ahead is a passage that turns downward, and obviously, this is not the deepest point...

From the hole in the side wall of the abyss, it could be seen that Ling Feng's current position was the top layer of the entire underground fortress.

If it weren't for the black ancient ants hollowing out the rocks beneath the karst landscape, I'm afraid this underground fortress would not have been exposed.

After walking all the way down the passage, it immediately became a large hall.

The hall is supported by dozens of thick stone pillars.

There are various rooms around the hall, all with closed doors.

Ling Feng walked into the hall, and suddenly some carvings on the stone pillars caught his attention.

The carvings are badly worn, but some are still recognizable.

Among them, a creature with a hideous face is vaguely recognizable.

Its head is slender, its facial features are sunken, and its limbs and body are extremely elongated, making it look particularly awkward.

"This must be an abstract painting!

In addition to such creatures, there are other creatures carved, all of which look very strange and cannot be found in the slightest resemblance in life.

Ling Feng looked at the stone pillars one by one, and the creatures on each stone pillar were different.

When he saw the last stone pillar, Ling Feng couldn't help but feel a chill down his back.

The three creatures on this, Ling Feng had seen before.

It was the black sand vines, the unknown black creatures and the black ancient ants.

It's just a little different, the color of these three creatures is actually white.

There is no doubt that they were all transformed by the Nine Great Families in the later period with the Black Gu Tai Sui.

The white black sand vines and black ancient ants, Ling Feng had already seen them, but the white creatures with two meters of tentacles had never seen them.

Just as Ling Feng had finished looking at all the stone pillars and was about to go to the various rooms to inspect them, a sudden cracking sound came.

This sound is all too familiar to Ling Feng...

It's the rock that is shattered...

Ling Feng's nerves immediately tensed, and when he looked around, suddenly a slender black shadow slipped down from one of the stone pillars.

Immediately, the black shadow swam towards Ling Feng at an extremely fast speed.

Yes, they swam over, but not in the water, but in the rocks of the ground...

Ling Feng secretly felt bad, wasn't this the unreasonable creature he saw on the first stone pillar?

After a few breaths, the creature swam to Ling Feng's feet, and immediately poked out its sharp fangs from the rocks and bit down on Ling Feng...

Ling Feng frowned, and immediately jumped up to avoid its bite, and at the same time, the bronze javelin pierced directly...

Immediately, there was a sound of metal crashing against a rock, and the creature was pierced without making a sound.

Immediately after, a ghostly light swirled from its surface towards the bronze javelin.

The creature turned white.

"It turns out that this has also been transformed! But how can so many creatures be modified? Was it modified, or was it the contamination of these originally white creatures during the experiment? ”

Ling Feng was also a little uncertain at this time...

He drew his javelin, and the creepy wasn't dead.

Obviously, it is not an easy task for such a creature to kill.

The creature was shaped like a tongue fish, flat and long, and its body was still in the rocks, except that its head was exposed outside the rocks.

"There is even a creature that can survive in the rocks, and its body is actually one with the rocks!"

"That is, it doesn't have a body of its own, the rock is its body! Isn't that what the black sand vines are? ”

"What kind of existence do they have?"

…
