Unable to make any useful discoveries along the way, the black bear simply gave up his plan of careful search, and led the seven members of the fourth detachment along the main streets that ran through the city to the center of the city.

The city is characterized by the fact that the buildings on the outskirts and periphery are the lower they are, and the closer they are to the center of the city, the more majestic they are.

"This place is either a government council, or a church temple!" The black bear said as he stood on the steps of the tallest building in the center of the city.

There were thousands of steps in front of him, and the height of each step was about thirty centimeters, far exceeding the height of human habit; Dozens of huge stone pillars on the steps support a huge dome more than ten meters high, forming a huge space in the building, which at a glance cannot help but remind people of the temples of ancient Greece.

It's a pity that the tenacious stretching plants in the cracks of the stone destroy the original sense of sacredness, adding a bit of dilapidation out of thin air.

Fortunately, the main building material here is stone, so it can still maintain part of its original appearance after being abandoned for so long, if it is a city built of reinforced concrete like humans, it will be dilapidated for decades, and it will collapse into ruins in a few hundred years, if it is a thousand years later, I am afraid that all the traces of human existence will be covered up by a long time, and there will be no trace of existence.

Man-made materials may have much better performance than natural materials, but natural materials can withstand the erosion of years and winds, while man-made materials can only slowly disappear.

This is also the point that many believe that there were prehistoric civilizations in the history of the earth that far surpassed modern humans. One of the reasons why I can't find ironclad evidence is that I can't find it!

The black bear held his position and took a few clear close-ups of the tallest building: "Chief, I'm ready to go in." ”

"Stay safe!" Ye Fei instructed.

"Don't worry, if you find out that it's not for me, you will withdraw immediately." The black bear turned on the auxiliary power and jumped up more than a dozen steps.

The warriors followed, leaping forward like a troop of frogs, and in a few moments the group reached the foot of the great stone pillar at the top of the steps.

At this time, it was just past noon, and the scorching sun was shining on the earth, and bursts of water vapor were rising.

The sun shines unusually brightly on the outside, while the interior of the building is very dark due to the shadows. Even if the black bear is only a few steps away from the shadows inside the building. I can't see what's inside.

The black bear did not want to take any risks, so he put his rifle on his back and took off a flare and stuck it in the muzzle of the pistol. Shoot flares steadily into the building.

Gun grenades must use 5.5 mm bullets to fire. In peacetime, it was customary for fighters to use rifles to fire grenades. But the black bear changed to a large-caliber rifle today, and fortunately, the pistol was designed with a barrel outside the sleeve, which can fire grenades. It is also possible to install a silencer.

Although the height of this building was the absolute highest in the city, its dome did not reach the point where it could exceed the range of a grenade, and the flare slammed into the dome, and a lightning white light exploded.

The ball of light paused for only a moment before falling down.

Due to the lack of height, the small parachute on the flare failed to open, and the body of the projectile fell directly to the ground from a high place, but this short moment was enough for the black bear and others to see the situation inside the building.

An empty hall, nothing more, and one of those vaulted halls, the black bear searched all his memories, and felt that the closest place to this place was the church, except that there were no rows of chairs, and there was no crucifixion.

The black bear was immediately disappointed, but everyone had arrived here, and there was no reason not to go in and retreat directly.

Walking into the hall, the flares that fell to the ground had not yet burned out, and the bright light illuminated the surrounding space, and the black bear suddenly found countless mottled murals painted on the walls around him, and he was stunned for a moment, and then he was overjoyed.

Words need to be translated accurately, but murals don't, and the paintings on the walls are the most visual way to convey certain information!

"Iron sheet, quick, one person, one position, hurry up and scan the mural!" The black bear urged excitedly.

"Wow, this is good!" Tin Hide was amazed and immediately began to arrange.

The warriors were assigned by Ironhide to go in all directions, one mural after another, and Ironhide himself and the black bear were no exception.

Several of the warriors who had been assigned to the frescoes in the dome had to fly into the air.

I don't know how many years the murals here have existed, and the original color has faded, leaving only simple black-brown lines to outline different scenes.

Ye Fei in the bridge of the Aquila witnessed all this in real time through data sharing, but in his impression, in addition to the ancient murals showing the scenes of daily life, similar to this kind of large-scale buildings with a certain level of civilization are painted with unreliable content such as legends or religion, which is almost not helpful for understanding the scientific and technological level of the aborigines of the Blue Star.

The reason why the black bear was not stopped is that through the murals, we can indirectly understand what the aborigines of the area are like - even if the content of the murals is all from mythology, at least the images of the gods must be from intelligent beings!

Whether it is ancient Chinese mythology, ancient Indian mythology, ancient Greek mythology or Norse mythology, the image of the gods is based on human beings themselves, such as the gods of ancient Egypt with human bodies and animal heads, which are really examples of individual cases.

A high-definition scanned mural was sent back to the Aquila, and no one cared about the meaning of the mural, everyone paid attention to the image on the painting.

The main element on the mural full of vicissitudes is indeed an erect creature, but this creature is somewhat different from the human image, the head is tilted forward and the mouth is prominent, although the lines are very simple, but from the outline, this creature is very strong, and the biggest difference between them and humans is that in addition to two legs, there is also a thick tail.

With the exception of this erect creature, the other depictions of the mural are non-erect beasts, making it easy to distinguish between the two.

Ye Fei couldn't help but look at the mural on the screen and nodded: "Similar to the bones found in orbit, those spaceship fragments should be the natives of the Blue Star." ”

Scissors sizzled: "The gravity of this planet is so high, how can the evolved creatures be so large?" "Theoretically, the stronger the gravity, the more gravity the creature has to overcome, and the smaller the body should be. (To be continued......)
