This medium-class world had a starry sky of tens of billions of light-years. Countless black holes and stars filled the starry sky, forming a magnificent and vast sea of stars.
On the outside, it was a beautiful sea of stars, but on the inside, it was a dead land.
There was no life in the infinite starry sky.
Because it was the Age of Doom.
The original life-bearing planet had become a planet with a harsh environment without life after evolution.
Only one planet was still the cradle of life.
Planet New Sun.
Planet New Sun was the only planet with life in the entire medium-class world.
Due to the Age of Doom, the humans on this planet were the same as the creatures and civilizations in the universe. 80% of the civilizations after the Age of Doom took the path of technological civilization. This was the evolution of living beings.
The remaining 20% could only be said to have a low potential. They did not evolve into a technological civilization and were still in the ancient civilization stage.
Liu Yu didn't seem to have anything to do here.
It was purely because Liu Yu, who was at the Eternal Sage level, didn't know how long he could live. He had to walk around, right?
Just like that, Liu Yu arrived at the One Thousand World.
Liu Yu naturally knew about the Age of Doom and understood it, but he had never experienced it physically and mentally.
This time, Liu Yu planned to stay here for a while.
The entire planet New Sun was very large. It had seven continents and ten oceans.
Liu Yu could clearly sense that there were some ancient existences in the depths of the sea. The weakest were at the Nascent Soul level, while the more powerful ones were at the Combination level.
However, they were all in a deep sleep.
On the continents outside the sea, there were also many ancient existences in the depths of the earth.
As for the appearance, there were no extraordinary existences on the entire planet. There were no extraordinary items either. Even if there were, they were also in a deep sleep.
This was a civilization that was about to enter the interstellar era.
However, the interstellar era would disappoint them because the infinite starry sky was peaceful. Their civilization was lonely. Although there were no life-bearing planets, they could still change it with technology. This was also one of the many escape routes of the medium-class world's consciousness.
A technological civilization could naturally make a universe rise.
The population of the entire planet was 30 billion. It was already at the point where there were too many people and too few resources. Therefore, the seven states had begun to march into space. This slogan had been shouted for more than ten years.
Even if a lot of money was spent every year, the results were still not great.
Technology was not something that could be achieved overnight.
What's more, Planet New Dawn had only been in the modern era for two hundred years.
However, Planet New Sun was extremely huge. Modern technology had not made much progress in the past two hundred years. Large amounts of resources had been expended for nothing. When the population and resources reached their limits, the countries in the seven continents began to panic.
Although modern technology couldn't colonize space, it wasn't too bad. If they didn't enter space, they would be swept in and eventually destroy themselves.
In order to save themselves, seven countries in seven continents signed a border law.
In other words, there were no large numbers of troops stationed at the border area, only daily patrols by the police.
Within the country, the seven nations originally had over 100 million soldiers, but now they were only left with 10 million soldiers. Ninety percent of them had been reduced.
And these funds were used to research aerospace technology.
With such a huge amount of research funding, after more than ten years of development, they had developed some skills.
Although space colonization was still far away.
But soon.
There was a satellite next to Planet New Dawn, which was Planet New Dawn's moon. There were more than 100,000 researchers from the seven major countries on Planet New Dawn. In just over ten years, Planet New Dawn's development was quite fast.
However, the development of things was often unsatisfactory.
Breaking through the threshold of civilization would also lead to disaster.
This was the disaster of civilization. If they survived, they would naturally move forward and become a huge technological civilization. If they failed, everything would start anew and wait for a new civilization to appear.
Planet New Dawn.
Demon City.
Zhang Mou opened his eyes. Didn't I die under the claws of a Lord-level monster? Why am I fine now?
Zhang Mou thought to himself.
Zhang Mou, who was at the window, felt very complicated.
Although he didn't die, he lost the ability to split mountains and split seas.
The world was still prosperous.
People, including the various countries, didn't realize that in five years, the entire Planet New Dawn's spirit energy would recover. At that time, human civilization would be destroyed.
