After a civilization is destroyed, how long can the traces that can prove its existence be maintained?
Hundreds of years?
Thousands of years or tens of thousands of years?
It seems to depend on whether there are any remains of this civilization, such as buildings like altars, or armor and weapons like those in the waterfall cave.
All these can prove that a civilization has existed.
Or...
For example, in the Dinglong Mountains, there is a small base on a high slope between the wooden house base and the giant sword base, as well as the dam base of the Na Ning tribe.
These architectural remains can also prove the existence of a civilization.
Similarly, the black bricks used inside the giant buildings in those V-shaped passages also have this effect.
If we look at the civilizations on earth, Stonehenge seems to have the longest history that can be traced back. It was a product of the Neolithic Age and has been preserved until now despite the constant erosion of nature and some human activities.
It is much more difficult to trace back further into the history of time. Many traces of civilizations that have appeared on the earth have been completely erased and cannot be traced back at all.
Therefore, after the destruction of civilization, the value of the buildings or other things left behind by them, as long as they can prove the existence of this civilization, will become higher and higher as time goes by.
Antiques are expensive for a reason.
If a civilization existed for hundreds of thousands or even tens of millions of years, what if it is proven that this civilization existed?
In fact, this mainly depends on the level of development of the civilization. If things like steel are placed on the surface for decades, they will basically disappear when the wind blows and rains. If they are buried under the ground, they will last longer, but that's not the case. There is no way to reach thousands of years.
It takes less than a few decades for the ruins of the city to be directly covered and decomposed by the vegetation on the ground, and the changes in the rivers, lakes and seas with the movement of the earth's crust can completely bury some ruins.
The ruins of the lost civilization will eventually be isolated from the world!
The special environment on the Snow Star, with its eighteen-month long cold winter and the extreme transition period between spring, summer, and autumn, seems to have provided natural conditions for the preservation of civilizational relics.
Without that very short period of spring, summer and autumn, some civilization relics seem to be preserved for a long time...
Ye Qiong's shock came from the platform in front of the big hole in the mountain!
If you look down from the air, the first impression you get is that this platform is very big and very long!
The width is about fifty meters, and the length soars to more than one hundred and fifty meters!
The end of this long platform is the big hole in the mountain.
The other section facing outside the Dinglong Mountains is not a cliff, but its slope is still very steep, about 70 degrees. It is difficult for humans to stand on it, so they can only use climbing postures.
Such an area can only be discovered by looking down from the air.
Looking up from the bottom of the mountain, there are only dense forests and endless vegetation of large trees.
Ye Qiong's first thought when he saw this platform was...
track!
What is it used for?
The kind where planes take off and land!
It’s so similar!
However, Ye Qiong definitely didn't dare to directly confirm this matter now. He could only suppress the excitement in his heart and stabilize the thunder in the air, which also started to get a little excited after feeling his excitement.
There was no way Ye Qiong could help it. Seeing the long platform below, Ye Qiong really couldn't calm down.
What is this thing for?
The problem is that this platform is directly linked to the big hole!
Suppressing the curiosity and excitement in his heart, Ye Qiong landed on the platform with Qing Zhi and Hua Huangji behind him.
The platform with a width of more than fifty meters was riding down on a thunderbolt, which suddenly made Ye Qiong feel like he was in another world.
The standard dimensions of an aircraft carrier...
Judging from the size of the Thunder's wings after they are unfolded, after landing on it, the adult Golden Eagles following behind can only land in some areas behind. If they land on the left and right sides at the same time, it will feel a bit crowded. .
However, this kind of crowded feeling is naturally not compared to Feng'er, whose size is incomparable to that of a normal adult Golden Eagle.
Thunder's body size has reached the level of a king. After its wingspan is spread out, it gives the impression that it is twice as big as the wingspan of a normal adult Gale Golden Eagle.
The visual impact is very shocking.
Therefore, on this platform with a width of about fifty meters, the thunder landed in the central area. Only after retracting its wings will the sides look wider.
Following the landing of the Gale Golden Eagle, you can land at will. As long as they don't land side by side, there won't be a big problem.
"Buzzing..."
Thunder had already landed on the platform, and Ye Qiong was not in a hurry to jump off.
It’s not flat grass down there…
There are some grey-brown vine marks on it.
On the surface, vines will grow wildly in spring and summer, and will not stop growing in autumn until the first snowfall of winter.
The cold will wrap up those vines in a very short time.
So there will be a scene where there is a layer of vines below and snow on top.
As the thickness of the snow increases, in early winter, there is a layer of vegetation below and above the ground.
The temperature of this layer will remain above zero for a long time. At this time, some ice insect eggs below the surface will begin to hatch, and the layer of vegetation area sandwiched between the ice and snow and the ground will become ice. food for insects in early winter.
Some small animals will also feed on it and will enter hibernation in mid-to-late winter.
On this platform, what Ye Qiong saw was not the vegetation that had been eaten and decomposed by ice worms and small beasts, but some gray-brown vines and some things that had turned yellow.
There are big and small ones, very much like...
Fruits!
Ye Qiong's curiosity was immediately aroused. He raised his head and glanced at the big hole on the platform in front. It was so dark that he couldn't see anything deep inside.
For the time being, he focused his attention on the ground, so he jumped up and jumped directly from Thunder's neck.
"Bang..."
"Bang...bang bang..."
Qing Zhi and the warriors behind him also jumped off the backs of their respective Gale Golden Eagles and gathered around Ye Qiong's position.
At Ye Qiong's feet, there was a yellow ball.
As the poison could not be ruled out, Ye Qiong naturally would not touch it with his hands, so he raised his right hand, reached for the quiver behind his back, and pulled out a large iron arrow from the quiver.
"Huh? What is this... it looks like... edible?" Qing Zhi came to Ye Qiong and saw Ye Qiong walking towards the yellow ball next to him with an arrow, so he immediately followed him , after arriving, I asked curiously...
