Although Iska still refuses to believe it, what has happened in the past few days makes her have to believe it. Since Chu Tianjiang is not a farmer on the farm, his skills, especially his rich knowledge, as well as his survival skills in the wild, show that he is definitely not an ordinary person.

Could he really be a savior!?

When going up the mountain, Iska deliberately pulled behind.

In Iskar's understanding, there are only three kinds of people in this world. The first is the lackeys of the Church and the Empire, the second is the common people who are oppressed and enslaved by the Church and the Empire, and the third is the warriors who secretly rebel against the Church and the Empire. Obviously, Chu Tianjiang does not belong to these three types of people.

Although there are some exceptions, such as the wandering rangers, the detached ascetics, or the robbers who live outside the system, none of the people with strong personal abilities are farmers on the farm, or even have anything to do with the farm.

You must know that the farm represents remoteness and danger, and only desperate people will go to live on the farm.

With a little ability, it is impossible for a strong person to survive in this world as a farmer, let alone let the church and the empire enslave him.

A person as strong as Chu Tianjiang definitely didn't come from the farm.

Iska wanted to ask, but she knew that if Chu Tianjiang refused to say, it would be useless for her to ask.

The more he thought about it, the more doubts grew in Iska's heart.

Chu Tianjiang didn't know what Lu Dao Iska was thinking, he just wanted to climb to the top of the mountain now, stand high up, and take a good look at this place known as "Ice and Snow Ridge".

After more than two days of exploration, Chu Tianjiang already had a general impression of the "Ice and Snow Ridge".

This is not a mountain range, but a basin between mountains. Because it is surrounded by towering snow-capped mountains, outsiders call it a snow ridge.

What's more, there must be a secret buried in this basin.

When he was about to reach the top of the mountain, Chu Tianjiang stopped.

According to the measured air pressure, the altitude here is already more than 6,000 meters. This is only an estimate, because the figure does not know what the sea level pressure is in the world of the Lunar Channel, so it is impossible to accurately measure the altitude through the air pressure, and can only refer to the previous data to give an approximate result.

Standing at this height, you can see the basin at an unobstructed glance.

I have to say that Chu Tianjiang's luck is very good, because the basin is a clear sky, and there are no clouds to block the view.

With just one glance, Chu Tianjiang understood.

This is not a naturally occurring basin, but a man-made basin because it is an extremely regular circular basin. What's more, the edge of the basin is noticeably lower, and although it is covered with vegetation, it is a distinct ring when viewed from above. In addition, the surrounding peaks are extremely steep on the basin side, and the terrain is very steep. If the basin is naturally formed, such as a volcanic crater or a crater, then the surrounding peaks will definitely have different shapes. As for the distribution of vegetation in the basin, affected by temperature and precipitation, the south is the cold forest, and the north is the ice and snow tundra.

"Did you find anything?"

Chu Tianjiang glanced at Iskar and did not rush to speak.

Before going up the mountain, Chu Tianjiang said that there was a secret hidden in the Ice and Snow Ridge, and the purpose of going up the mountain was to find this secret, so Iska asked him so.

Chu Tianjiang didn't rush to answer because the figure was analyzing.

After a moment, Chu Tianjiang's guess was answered, and the mountain basin was indeed the remains of a man-made facility. After being reminded by the figure, Chu Tianjiang pulled up a windproof hat made of bear skin and covered his face. Because of the strong wind on the mountain, this move did not attract the attention of Iska.

The figure displayed the virtual three-dimensional scene in front of Chu Tianjiang.

Although it was only a shrunken three-dimensional image, Chu Tianjiang could still see it clearly.

Using the information obtained, the figure depicts a man-made structure with a dome structure, i.e., a structure that resembles a pot lid that covers the entire basin. Subsequently, the figure began to speculate on the overall structure of the building, and came to a conclusion that surprised Chu Tianjiang.

This is supposed to be a spherical structure, less than a tenth of the total volume exposed to the ground, and the rest is under the ground.

Immediately, the figure gave a conclusion that surprised Chu Tianjiang even more.

Originally, the building was entirely underground, and in order to resist external impacts, it was designed to be a spherical shape with the highest strength of the stressed structure. A blow from the outside blew up the topmost part of the building and created this mountain basin, while the part below the building was buried.

Obviously, the building has an entrance, and most likely in the center of the circle.

After the figure came to this conclusion, Chu Tianjiang pulled down his hat.

"How?"

"Let's go to the middle of the basin and have a look."

Iskar nodded, not saying anything more.

Before coming here, she had always thought that this was a mountain range, but when she saw the basin at the foot of the mountain, she immediately realized that Chu Tianjiang's judgment was not wrong.

There must be an amazing secret in the snowy mountains.

It was almost evening when the two of them reached the foot of the mountain. Because there was no night demon appearing, Chu Tianjiang didn't plan to wait until after dawn to investigate.

In the second half of the night, Chu Tianjiang took Iska to the center of the basin.

Although there are torches to illuminate, it is still a hassle to find the entrance to the ruins. The main thing is that this ruin may have been built thousands of years ago, at least more than 1,500 years ago, and that devastating blow must have released a huge amount of energy and caused a geological disaster. Even if the entrance to the ruins had not been completely destroyed, they would have been buried in the ground by now, or even blocked.

Of course, all Chu Tianjiang needs is time.

The figure's detection system is capable of detecting situations within a one-kilometer radius, and the atomic-level detection device is not blocked by matter.

When it was almost dawn, the figure was discovered.

After digging through the soil layer about one meter thick, Chu Tianjiang found the entrance to an underground karst cave, which was not very wide and could barely allow one person to pass through.

Even if there is no figure to introduce, Chu Tianjiang also knows that this is not a naturally generated karst cave.

The reason is simple, the cave is made of melted rock, and the interior space is very large. According to the results of the figure analysis, this is the former breaking point. The building was supposed to be destroyed by a very powerful bomb, which released the equivalent of 100 million tons of TNT explosives, but no nuclear radiation was detected, so it was likely to be a pure fusion bomb, or an antimatter bomb. The high temperature generated by the explosion vaporized the material near the explosion point in an instant, but the shock wave generated by the explosion was transmitted to the outside world at a faster speed, creating a high-pressure field nearby, causing the vaporized silica to condense near the explosion point. As the temperature near the explosion point decreases rapidly, the vaporized silica begins to solidify, eventually forming a powdery solid substance. Because the rate of solidification is not the same, and the degree of aggregation is different, these solid materials form a complex cave structure.

Under the guidance of the figure, Chu Tianjiang took Iskar all the way to Luxia.

How long has it been, Chu Tianjiang didn't have a clear idea. It wasn't until he stopped that the figure reminded him that almost eight hours had passed.

That is, it was already afternoon outside.

After eating something, Chu Tianjiang took Iskar and continued to go deep into the cave.

Comparatively speaking, the temperature inside the cave is a little higher than outside, but it is very humid. Although I walked for a long time, the height of the vertical descent was not large, mainly because the structure of the cave was too complex and I took many detours. If you descend vertically, it won't take so much time at all.

After walking for about four hours, the figure reminded Chu Tianjiang that the entrance to the ruins was ahead.

"This is a relic of an ancient civilization, and after the era of catastrophe, the history is about 5,000 years old."

"Are you sure?"

"You can use the semi-handsome cycle of the primordial elements to confirm how long the ruins have existed."

"So the building was built five thousand years ago?"

"About 5,000 years, plus and minus errors are no more than 100 years. Want to know the function of this building? ”

"What?"

"A laboratory."

"Lab!?"

"If my speculation is correct, this was established by the Shadow Empire, whose main function is to test the antibodies used to completely kill the genetic virus."

Chu Tianjiang's brows jumped a few times, according to the information he had obtained before, he had already learned that the Shadow Empire had killed the genetic viruses in the atmosphere, saved many people, and also allowed the newborns of the survivors to no longer be infected, fundamentally preserving the foundation of human civilization.

"When was it destroyed?"

"About fifteen hundred years ago."

"Fusion bomb, or antimatter bomb?"

"Neither, it's supposed to be a pure energy body bomb."

"Energy Body Bomb!?"

"Or it's a weapon related to space technology, which is very powerful, otherwise it wouldn't have caused so much damage. It's just that the building was not completely destroyed, the lower part remained, and the damage was not very serious. The central system that controls the building is highly intelligent and able to operate completely independently. To put it bluntly, this is a building with artificial intelligence. ”

"What else?"

"It's alive."

Chu Tianjiang wasn't surprised, because he had already guessed the result. It is precisely because of this that the Night Demon does not dare to enter the Ice Ridge.

"It's not a relic of Clara, though." The figure reminded Chu Tianjiang.

"How do you get in?"

"The entrance is behind the rock wall in front of it, and it's about two meters thick. Don't use too much force, the cave is made of silica powder, which has been deposited for 5,000 years before it becomes stronger. If you use too much force, the cave will collapse due to structural damage. ”

Of course, Chu Tianjiang understood the meaning of the figure, the cave collapsed, and he and Iska would be buried alive.
