Erlu originally planned to give them and find a few mounts to explore the underground world together, but they sternly refused.

What are you kidding? They're a cloth armor class, and they're not knights like a steel can, sitting directly on a giant armored dragon with bone spurs, and they'll pierce their butts, right?

After Erlu had dealt with the giant armored dragon group, Eryi and them also floated down from the edge of the ice and snow sinkhole.

Looking at the bottom of the sinkhole, Er Yi felt that he should cover up this place, otherwise he would have to make a fuss for a while if it was discovered by the group of scientists who were engaged in scientific research in Antarctica.

However, the two ones in the inflated state are not suitable for infrastructure construction.

So he asked Eryan to summon Sister Vicky over, and in this environment, she just exercised her ice and snow ability.

At the same time, he summoned the Yeti Yeti clan on the fourth floor of the ladder and the [Deep Cold Snow Field] plane to give Vicky a hand.

The initial plan is to build a large Antarctic base based on the ice and snow sinkhole.

The first is to guard the exit of the warm cave to prevent any more dinosaurs from running out.

The second is that the second one has a hunch, and the sudden appearance of the underground cave must not be as simple as running out of a group of dinosaurs.

Entrusting the construction of the Antarctic base to Sister Vicky, Er Yi and the others hurriedly entered the underground cave, following the traces left by the giant armored dragon, all the way to the depths of the cave.

To their surprise, unlike the ice and snow on the surface of Antarctica, the Antarctic underground is full of life.

Huge underground cavities are filled with thick moss and dense algae, as well as incomparably large fungi covering the entire underground space.

The abundant volcanic hydrothermal vents ensure a warm and humid microclimate in the underground space.

All kinds of strange bugs and small animals that have not even been on the biological atlas of human civilization.

It thrives and thrives in the vast underground cavities, and it is clear that a self-contained ecosystem has been formed.

In addition to the group of giant armored dragons that accidentally escaped from the surface, a wide variety of dinosaur groups lived here leisurely, making people wonder if they had traveled back to the Jurassic era.

Eryi originally thought that the underground space of the Kunlun Void Base was huge enough, but compared to the underground space here in Antarctica, it was a drop in the bucket.

After all, it is an environment that can accommodate a giant creature like a dinosaur.

The huge space makes people wonder if they are underground, or some magical foreign world.

I don't know how such a huge underground cavern has supported the surface of the earth, and it has not collapsed for countless years.

Along the way, I hardly found any narrow places of them, and I couldn't help but be amazed, it's not that I don't know, it's really the world is too wonderful!

What's even more surprising is that they also found traces of human activities in the underground space, not the remains left by ancient humans, but traces of modern humans with a fairly high degree of technology.

Although most of them are abandoned camps, as well as settlements destroyed by dinosaurs.

But judging by the remnants, these underground humans have been living here for quite some time.

The longest of the abandoned camps and settlements is no more than 100 years, and the shortest can even be seen to be about 10 years.

They couldn't help but look at each other, could it be that the legendary Aryan dungeon in the Antarctica of the Third Reich was real?

It seems that there is only one explanation, because the scale of the human relics found by them is not small, and there are even large mining areas and factories, and there are traces of war in many places.

The so-called "traces of war" do not refer to some small-scale small arms conflicts, leaving behind a few bullet casings and other remnants, but the surrounding environment with large-scale heavy weapons and violent explosion craters.

Although most of the ruins have been hidden by the natural environment, there are almost no visible traces of erosion in the warm and humid environment of the underground warm cavern.

But they still found a railway rail network extending in all directions under the thick moss layer, which shows that there was a train as a means of transportation here!

Legend has it that during the heyday of the Third Reich, there were often cases of the disappearance of formed armies or large-scale disappearances, and some people wondered whether they were forcibly relocated to some mysterious place under the supreme order of the Führer.

According to statistics, the number of troops who mysteriously disappeared during World War II was as high as hundreds of thousands, and the number of missing people may even exceed millions.

Although this huge number is hidden in the casualty statistics of 60 million in World War II, the strange situation of missing some of them and not seeing the dead or the corpse will inevitably leave the world with inexplicable doubts.

Regardless of whether the existence of the Aryan dungeons of the Third Reich is true or not, at least there is no doubt that the human relics they found are left by modern humans.

It's just that I don't know why, the human remains found along the way are showing traces of destruction, and the second one doesn't think that this is what dinosaurs can do.

After all, no matter how powerful the dinosaurs were, they were just beasts, and under the blows of modern high-powered thermal weapons, it was impossible to resist the hunting of humans.

In addition, the food resources in the underground world are very abundant, and even the most brutal dinosaurs do not need to target dangerous humans as prey targets, which leads to the reason why these human settlements are abandoned.

It's hard to be in this underground world. What else is worthy of the existence of the elite troops of the Third Reich, a powerful enemy who is fighting hard?

Searching all the way along the human relics, they have traveled hundreds of kilometers underground, and found a lot of underground rivers, underground lakes, and even deep water caves connected to the underground sea along the way.

The environment is too complicated, so even if they are two, it is difficult to explore this place in a short time, so they simply stopped by an underground hot lake, it is indeed a little difficult for the four of them to explore such a large underground world, and decided to rest on the spot and wait for reinforcements to arrive.

The so-called underground hot lake refers to the fact that the temperature of the lake is quite high, and it is conservatively estimated that it is also seventy or eighty degrees, such an environment is actually not suitable for the survival of living creatures, but the four of them only relaxed their vigilance slightly, and they were attacked by an underground troll hidden in the hot lake!

It was a transparent creature about a meter thick, looking a bit like a snake or an eel, it lurked motionless in the lake near the shore, because of its natural protective color, coupled with the lack of any life reaction, even the second one was blinded and did not notice its existence.
