Cheng Lin was surprised to see that people stopped digging after reaching a certain depth underground, probably because this depth was no longer cold, and then they began to expand horizontally, and the scale of the entire underground city was rapidly expanding.
"The shift from vertical to horizontal means we need to recuperate and develop productivity, right?"
Cheng Lin thought that during the excavation period, the main consumption was the food accumulated on the surface, while the establishment of underground cities requires more diverse energy supplies and food sources. This is a problem that humans need to overcome.
Details were not visible in the picture, but through overall macro control, Cheng Lin was pleased to see that the underground city was gradually becoming more prosperous, and the population seemed to have finally stopped its downward trend and began to slowly recover.
At this time, the overall structure of the entire underground city was already very complex and chaotic. After the initial hasty and desperate excavation, people finally began to seriously transform the living environment. This reminded Cheng Lin of "historical necessity", such as the
It seems that today's underground city dwellers are also undergoing this transformation, such as pollution first and then treatment, economic first and then culture.
During this period, some social changes seemed to have taken place. Cheng Lin discovered that during a certain period, people stopped working and started fighting. Even though he could not see the specific situation of the struggle, the overall situation was very clear.
"At first it was all about survival, and no other things were taken into consideration. Now it is starting to gain a foothold, so changes in the social structure are beginning to happen."
Cheng Lin was not surprised by this.
Moving from the ground to the underground is simply a change in survival, science, and production methods. This is the most obvious change, while the more hidden changes lie in the fragmentation of the entire world and the destruction of the original order.
"For example, one of the serious problems is information isolation. After the world was frozen, people in various regions went underground in unison, so the large structure of globalized information communication suffered a devastating blow.
Originally on the ground, starting from the Age of Discovery, global information exchange has completely ended, and every underground city is an independent individual.
Information is blocked, trade is stopped, and at most, we can only have limited communication with a few surrounding underground cities, which is bound to have some kind of retrogressive impact on the form of human society."
Cheng Lin was floating in the air, facing the huge "ice ball" in front of him alone, muttering to himself.
This change in form may also breed new ideologies... but these cannot be seen with the eyes, so he can only guess secretly.
However, the overall transition is still relatively stable, which is good news. Cheng Lin is really worried that humans will survive the cold winter but die from internal fighting.
Finally, the horizontal expansion of the underground city also stopped, and several passages touched mineral veins and underground resources, coal, geothermal heat, ores, underground rivers... They even started cultivating plants underneath.
A true underground city emerged.
Then, Cheng Lin discovered that humans began to build passages to the surface in reverse, mainly to stabilize the vents. The oxygen content underground was low, and vents had to be dug to keep the air flow smooth. However, the vents were often buried by wind and snow, and they had to be
Someone is always there to clean up.
As a result, a surface "observation station" based on the vents was established.
"Is it a mountain peak that was used?"
Cheng Lin was surprised to see that the observation station was not built in the city, but was dug through a tunnel and led directly to a nearby mountain peak.
"To put it simply, it is to hollow out the inside of the mountain and make holes on the side of the mountain. This can ensure the safety of the air holes to the greatest extent and not be blocked. At the same time, it also provides enough living and storage space for the observation station, as well as observation
The height of vision.”
Cheng Lin quickly realized the human intention.
This is a very smart approach.
"And snowmobiles..."
Cheng Lin saw that after the observatory was established, a strange snowmobile emerged from the snow-capped mountains. It was driven by strong practitioners and began to conduct short-distance operations on the surface, exploring the surface, collecting and transporting supplies, and drawing maps.
"Human beings still don't give up on the ground."
Cheng Lin sighed.
However, such exploration is ultimately limited. The main job of the observatory is to maintain the vents and try to re-establish global communications based on radio... The snowstorm and the restless aura between the sky and the earth make the propagation of communication signals very difficult, and the radio weakens very quickly.
, communication can only be carried out within a certain radius.
In addition, they faithfully record the changes in surface temperature every day, trying to wait for the day when the world "thaws" and look forward to the melting of glaciers and their return to the surface.
Invariably, almost the same process was carried out in underground cities around the world, and as a result, observation stations built on mountain peaks were erected one after another.
There was no communication, no communication, but all underground cities made the same decision.
This is not difficult to understand.
"Probably... all human beings long in their hearts to return to the earth."
…
…
Cheng Lin found that his clairvoyance ability had disappeared and his body was falling rapidly.
"Has time stopped accelerating?"
He thought to himself, stretched out his body control, and landed on the ground smoothly.
"puff."
When his legs touched the ground, he instantly fell into the snow due to gravity, and his entire body was buried.
"change!"
He was slightly stunned, waited for a while, confirmed that time was no longer accelerating, circulated all his spiritual energy, and uttered a word.
Instantly, two fireballs appeared around his body.
Low-temperature fireballs are no longer suitable for Cheng Lin to use in battle, but they are still very comfortable to use as assistance. The two fireballs quickly melted away the snow and quickly rotated around his body.
Soon, the snow within a few meters around Cheng Lin melted.
"receive."
Cheng Lin removed the fireball with a wave of his hand and stood in an almost perfect circular snow pit looking up at the sky.
The weather is exceptionally good today.
It was still very cold, but the sun was shining brightly, the sky was exceptionally clear, and the world was extremely quiet.
The world is extremely bright.
That was caused by the snow reflecting sunlight away. The atmosphere had been damaged, but the situation was still good. Cheng Lin took a deep breath, and the cold air entered his lungs, making him shiver subconsciously, as if he was drinking in the hot summer.
I took a big gulp of ice water and the pores all over my body shrank.
"If it didn't have the cold-repelling property, I'm afraid it wouldn't just be irritating, it would be painful." Cheng Lin thought.
[Fifty years have passed, and the remaining humans around the world have moved thousands of meters underground to start a new life, and a new ecology has already been formed on the ground]
[The coming of the blizzard killed most of the creatures, but after all, some creatures that were good at resisting the cold survived and began to thrive]
[The emergence of the cold wave is accompanied by a more violent and rich aura. This aura makes many plants mutate first, becoming extremely cold-resistant, with extremely deep roots, and are suitable for survival in glaciers and snowfields]
[With plants, animals have a source of food, and the violent aura and cold have prompted global creatures to undergo rapid transformation within a few decades. The cruel living environment has brought opportunities, and creatures living on the surface have begun to usher in great changes.
The awakening of the scope, with stronger physique, combat power, and moderate wisdom, almost all the creatures that have not awakened died, and the surface creatures ushered in a new round of reshuffle]
[Because humans went underground, they retained a larger population, but at the same time, they lost the opportunity to awaken on a large scale. Except for a small number of human practitioners, most are still ordinary people]
[The world has formed a new ecological layer. This time, human beings have finally lost their status as the master of the ground]
Information comes to mind.
Cheng Lin walked out of the snow pit while reading. The ground was not soft. Except for the few dozen centimeters of soft snow on the surface, most of it was hard ice.
This allowed him to successfully walk on the desolate and cold surface.
"Sure enough, there is a new ecology."
Cheng Lin stood on the frozen soil, dusted his clothes casually, looked up and saw a forest on the snowfield. The trees were dark, wide, and stretched out, as if they were trying their best to absorb the sunlight.
The appearance is distorted and arrogant, probably because no one is watching, so it grows casually and looks ugly.
There were other black, red, and orange strange-shaped grasses in the woods, and even some fruits, which were actually full of life, which surprised him.
"I originally thought the world would become extremely desolate, but I didn't expect... life can always adapt to the environment... Of course, those who can't adapt will be eliminated."
Cheng Lin walked over.
It is natural to feel the rich fire element in these black trees.
"These trees are also spiritual plants that have been transformed by spiritual energy. However, in the past, spiritual plants in my mind only referred to grass, flowers or fruits. The entire forest is full of spiritual plants... which is really rare."
Cheng Lin touched the dark, strange-looking tree trunk and looked around, but found no trace of the animal.
"Where are the animals? Didn't it mean that there are many awakened animals alive?"
he asked curiously.
