When the explorers first arrived at this cave, the captain Robert, biologist Franklin, archaeologist Saloyan, physicist Mike, geologist William, engineer John and a group of six people entered the cave at the same time under the excitement of Robert, wanting to explore the mysterious ruins of this ancient civilization.

Yes, the mysterious ruins, in their opinion, they are still in the Antarctic continent, but they have been teleported to an unknown valley by unknown means by ancient civilizations, and this cave hides all these secrets.

Of course, the discovery of this secret will leave a name for the ages, become a monument to human history, and a bright future is beckoning to them, so neither the calm old man nor the lively young man in the team has opposed Robert's seemingly dizzy opinion.

Continuing along the dark cave, the searchlights were almost out of power, and the cave had no end in sight, which was not to blame them, after all, they had consumed a lot of electricity on the way to the cave, and they had no intention of carrying out the separation operation at the beginning, so they naturally did not carry portable generators and batteries.

In order to ensure the normal use of the camera device, Captain Robert had strict control over the power used by the searchlight, but before the light of the searchlight disappeared, they saw a ray of light from the front, and it seemed that this long and unspoken passage had also reached the end.

Robert was very happy to see this, and along the way, he had recorded the frescoes that remained on the long passage, yes, there were some ancient frescoes on the walls of this passage, and this strengthened the conviction of the explorers that this was an unprecedented discovery.

Robert was relieved to see the entrance to the cave, it was just some frescoes, and if he expected, there must be a ruins of an ancient civilization hidden at the end of this passage, maybe they could still distinguish the buildings that had been there in this place where no one disturbed.

Seeing that the team members also seemed to be enthusiastic, Robert still led them to the forefront, and no one else competed with him for this credit, Robert, as the captain of the team, still has this prestige, and everyone will not compete with him for the title of the so-called first person at this juncture.

Walking to the entrance of the cave, Robert subconsciously held his breath, the scene in front of him made him feel deeply shocked, and his sudden stop also aroused the curiosity of the team members behind, they also gathered around, looked at the scene in the distance, and then fell into shock with Robert.

Not far from the mountain, there is a strange complex of buildings, although there are years of erosion, but these ancient buildings are still intact, different buildings still exude different lights, yes, this is not an open-air building complex, but built in the mountainside, artificially excavated a huge space.

The light they felt was also emitted by those buildings, and it was this that made them feel extremely shocked, it is hard to imagine that countless years ago, there was such an ancient civilization, they hollowed out the belly of a mountain range, built a city in it, and each of their buildings could emit light, this is simply a city that never sleeps in ancient times.

"Captain, I'm not mistaken, a glowing city, how is this possible." Mike was the first to react, and the sound of surprise also woke up the rest of the team members who were in a state of surprise.

"What's this, don't forget how we got here, I said it must have been a great discovery." Robert also came to his senses, his face flushed with excitement, and he was already sure that he would become the most famous Antarctic explorer based on the appearance of the city alone.

"Captain, shall we go in?" Mike was a little nervous, as a young man in the team, the moment he saw the city, he felt that this must be an alien base, although it didn't seem to have any sense of technology, but maybe it was the characteristic of this alien civilization, of course, he wouldn't say this idea again and argue with the captain.

"Of course, let's go down this road, and after we go down, we must take more photos and videos, this is our great discovery." Rob nodded and said to the people around him, he had seen a slope here, which should be the passage for primitive people to go up and down.

As they walked down the slopes toward the city, the group's smiles of joy faded into disbelief and were replaced by frowning thoughts and disbelief.

"Captain, the buildings here are not suitable for human habitation, and the scale of the buildings is too large, and the furnishings inside are very weird." Franklin approached Robert, and since entering the city, he had noticed many strange things, such as the fact that many details of the building were not suitable for humanoids, and this thought became even more obvious after entering the building.

It stands to reason that the buildings built by the ancient civilization that built such magnificent buildings are naturally suitable for the life of that civilization, but in terms of the current reconnaissance, these buildings are too strange.

First of all, the gates of these buildings are much higher than those built by normal humans, which may explain that the individuals of the civilization are taller than normal humans, but the interior of these buildings is very strange, there are no tools for sitting or sleeping inside, and there are no related objects left, it is difficult to imagine that the life that could build such a huge city would not have any furniture, which is a strange thing.

Mike, who was in the group, was very happy, believing that this must be the base of the aliens, and this was the evidence of the presence of aliens in Midgard in ancient times.

Soon after, they found a mural in the building, which confirmed this completely, this is indeed the base of aliens, from the mural, it can be seen that this is an alien creature that looks like a plant, they have a huge body similar to a spindle-shaped vat, with starfish-shaped limbs on the top of the body, five things that should be legs below, and a pair of wings on their backs.

Although the alien civilization is no longer a secret, compared with the miracle of the ancient human civilization, first of all, it is not so attractive, and secondly, the country will definitely not allow the relevant information to be leaked, but Robert thought about it, maybe he can rely on this matter to get benefits from above, and it will not be a loss.

A group of people who were full of interest adjusted their mentality slightly, and began to carefully explore this alien base, after all, the alien base is not as good as the ancient civilization, and there may be some high-tech traps, so the bold explorers have also become cautious.
