The end of the spiral corridor is like a pure black mirror, and everyone has the illusion that it is reflecting light.

Dozens of people were only a few meters away from each other, unusually cautiously walking towards the huge black cavity behind the end. When the temperature around us reaches minus 230 degrees Celsius, the air seems to have turned into colorless and invisible ice crystals, and inhaling the lungs will take away a lot of water. Everyone at least maintained the light that their bioelectric induction force field gathered a little bit to excite it, but whether it was the light or the perception of everyone, after entering the end, they all fell into the abyss that they could not break free from, and there was no feedback.

Everyone looked at their feet in tacit understanding, but it was still a black hard rock, a rock that could cause a crisp sound at the slightest collision. After a few breaths of silence in place, someone finally approached the end, and the heat wave swept around, revealing a faint form of a wide gray-white road that existed below, but the light still did not touch any boundary of the black void space behind the end. The frozen black, as if it hadn't been nourished by any nutrients and energy for a long time, had disappeared after the heat wave and light had gone out of a distance.

However, everyone understands that the ultimate reason is simply that this underground space is too large, and the influence that exists around them makes it impossible for them to let the light go to the boundary of this space.

"Rocky mountains and conch conch in ancient history. The man at the end of the tunnel turned around at this point, and after scanning the surroundings with the light on his fingers, he spoke, "We are probably somewhere in the center of this underground space, and although we have substantial rocks under our feet, it is not unreasonable to think that we are in a suspended state. As he spoke, the intensity of the light in the man's hand rose again, and the gray-white road dozens of meters below the spiral passage was completely exposed.

After listening to the man's words, Lisuman's mind already appeared in the pictures of rocky mountains and conch drawn by historians. In ancient history, it was a strange creature that lived in a huge sea area and lived by devouring rocks and underground volcanic lava. However, after various follow-up data, it is clear that rocky mountains and conches do not really live on magma and various rocks. It is so large that it can be called a moving island on the seabed, and it has a complex parasitic and symbiotic relationship in its body, and its food source comes almost entirely from these creatures. Rocks and magma are nothing more than the nourishment needed by parasitic and symbiotic organisms within it.

While thinking about it, the man at the front had already jumped off the end of the spiral corridor, and after a breath, landed on the gray and white road. Seeing this, dozens of people around followed the footsteps one by one, and when everyone was standing on the road, a few points of light suddenly skyrocketed, wanting to test the boundary limit of this space.

All failed, and the surging light was only a corner of the shell left behind by the dead rocky mountain conch above their heads. One or two unique circular spirals can be observed, and the rest is completely hidden in the darkness.

The off-white road extends to both ends with an upward slope. tacitly chose to walk to the high place together, and the footsteps became a relatively "low" knock at the moment. Although no one spoke, the gray-white road under their feet was actually the spine of some kind of snake in ancient history, and they were very clear in their hearts. It is known as a graveyard in bizarre writing, and it is quite normal for the bones of some ancient historical creatures to appear. In addition, as five-stage surgeons, the amount of knowledge in their heads allows them not to be surprised.

However, the white points of light that constantly sparked heat waves around Twelve O'clock completely lost their luster after entering this underground space. In Lisuman's eyes, including herself, there is a feeling like a candle flame that will go out at any time in the wind.

The extreme cold caused many things to change their normal state, and the condensed air made every step feel like walking in cold liquid metal. It was quiet, and the darkness around it was not only swallowing up light and heat, but also sound and perception, and everything that could be consumed.

The speed of the twelve gradually increased, and after a few breaths, it turned into a trot. The path of the spine seemed to have no end, and Lisuman calculated that after walking nearly seven or eight thousand meters, he still did not see any change. The spine that bites one by one at his feet remains the same, as does the black of the void around him. It was as if it had always been in place, and even the upward slope of the spine road had not changed in the slightest in the sense of everyone.

But with the hearts and willpower of the twelve, this labyrinthine road structure and the erosion of the surrounding environment cannot affect any one of them in the slightest.

It was only about two kilometers before everyone stopped at the same time. Something other than black finally appeared on both sides of the skeletal road. They were all gray and white bones distorted in the extreme cold, stacked on top of each other like garbage. Huge, tiny, straight, curved, all forms of bones that some collectors will surely enjoy.

Everyone who stopped looked at each other at this time, and they all understood what the others were thinking—the path formed by this spine was probably the true center point of this space, combined with the position of the spatial boundary that the light had just reached and the upward slope of the road、、、

They were now walking on a mountain of bones made up of the bones of countless ancient creatures. What's at the top of the mountain of bones, and at the center of this subterranean space? The bizarre text on the fossilized dragon skeleton doesn't tell all the information here, it's more like an epitaph copied much later, with only an approximate location.

As a cemetery, no matter the size of the underground space, or the almost endless spine road, the corpses of countless creatures that existed in ancient history piled up under the road are just a rough imagination, and it is enough to show the magnificence of this cemetery in ancient history. Everyone had the same curiosity and interest in their hearts for a while, and at the same time, vigilance also appeared in everyone.

Not knowing what the others thought of the cemetery, Lisuman walked at the back, following in the footsteps of the others, looking at the bones that had piled up below to become fossils. The extremely low temperature around her made her feel like she was back on the tundra at the moment. She was already guessing what kind of creature it was going to be associated with.

"It's just that with such a huge scale, what is the reason for the construction of this place?" There are many records of various cemeteries in the databases of the Holy Emperor Hall and other forces, and it is not that there is nothing of such a scale, but the things that remain in those cemeteries are extremely terrifying. The doubts in Lisuman's heart were completely covered by the danger signals that suddenly surged up in her body before she could enter the later stage of thinking.

A little white light suddenly bloomed high in front of everyone, far away from everyone, where it seemed to be the end of this spine path.
