At this time, Moko's voice attracted everyone's attention.

Xia Lian raised his head. On the right side of the assembly room, there was an iron staircase about three or four stories high. At the top of the staircase was a mechanical door, which was now open. Moko was standing on the handrail next to the door, facing him.

The door beckons.

They temporarily diverted their attention from the spaceship, walked up the stairs, and entered behind the door.

Behind the door is a place similar to a main control room. The octagonal space is surrounded by control panels and virtual projection screens.

"Your Highness, look at this." Moko pointed to one of the projection screens, which was playing images at the moment.

Like a top-down perspective, he saw towering peaks, spreading mountains, endless green grass and buildings on the land.

It was a house with a wooden frame structure. The streets were paved with stones. Women in simple clothes were shopping with their children on the streets. Animal-drawn carts were interspersed among them. It looked a bit like a small town on the edge of Europe in the 16th and 17th centuries.

.

"What is this? Video or real-time?" Xia Lian asked.

Moko looked at Aisha, who was in charge of technical support in the team.

Aisha stepped forward, stretched out her hand and touched the control screen above, and the picture on the screen moved accordingly. Starting from the small town, they moved across the mountains and rivers, and they saw a relatively prosperous city.

.

The architecture is beautiful and full of artistic sense, and there are many buildings made of high-grade limestone materials. It has a cathedral-like style. It seems that there should be worship of gods in this city.

A seven- to eight-meter chimney stands on the ground, spewing billowing black smoke and steam. This is a civilization that has just entered industry, and everything looks so prosperous.

"Monitoring?" Xia Lian whispered softly.

"They seem to have left a satellite in the orbit of the Evernight Star." Mercury walked up from the stairs on one side, and countless data flows seemed to be projected on her irises.

"It looks like it's still running."

Xia Lian raised his head and stared at the picture on the screen with his dark blue eyes.

"Those just now should be areas with normal day and night changes, right?"

"Yes." Elsa responded.

"Look at Yongye District." Xia Lian said.

Aisha nodded, and then began to control the LCD control screen in front of her. The images on the projection screen were moving.

Soon, the screen was occupied by a land of ice and snow. Everything as far as the eye could see was white snow, thousand-year-old frozen soil, storms mixed with ice and snow sweeping across the earth with destructive power. The entire sky was shrouded by a huge "black ball", and only the black

The edge of the ball is illuminated by scattered arc light.

The entire land was devoid of any life, and it was deathly silent.

This is the result of losing sunlight. Judging from the data displayed on the satellite, the average surface temperature here is almost -40°. Fortunately, this planet is not completely shielded from the star. Otherwise, the temperature should reach -68°C.

° below.

The coldness in this area will undoubtedly affect areas with normal day and night cycles, and their winters should be extremely cold.

This is not a planet suitable for human survival, but in this galaxy, it is the only planet that allows human beings to survive.

"Is there no one?" Xia Lian asked.

"There aren't even plants, so how could there be people there?" Karl said, "This land should be permafrost and not suitable for planting at all. Where will humans get food from?"

"That's not necessarily true," Moko interrupted, "I heard that thousands of years ago there were genetically modified crops that could be grown in frozen soil."

People in this era basically have no shortage of energy, and can directly use energy to synthesize food. With current genetic modification technology, as long as there is energy, a huge amount of food can be grown on a small amount of land.

It’s not that there is no good land, crops grown in frozen soil are completely unnecessary in this era, and they have naturally been forgotten by people.

Xia Lian said at this moment, "Under the premise of ensuring genetic diversity, there is a minimum number for a mammalian species to reproduce without degenerating.

Lower than this number will lead to a reduction in the genetic diversity of future generations and the degeneration of the entire population, and there is also a minimum number for civilization experiments.

Let's assume that the initial population they put on this land was 10,000..."

"Your Highness, there are data records here." Aisha flipped through the computer in the main control room and said, "The total number of people they released was one hundred and three thousand."

Xia nodded and continued: "If we want to continue for more than a thousand years and almost two thousand years, the population growth rate must not be negative, otherwise, their end will be destruction.

Although specific data cannot be calculated due to various factors such as the environment and medical care, based on the lowest population growth rate, the number of people who should exist in this land now is in the hundreds of millions.

But looking at the productivity of this paradise, the maximum number of people that can exist should be around tens of millions.

Excluding natural disasters, plagues and other factors, if they want to survive, they must artificially reduce their population.

War is inevitable."

"But they don't look like there is a war." Moko said.

"Yes." Xia Lian murmured in a low voice, "There is a problem. Where did the rest of them go?"

Everyone present frowned and fell into thinking.

"Your Highness." Elsa's voice attracted everyone's attention, "I think you should come and see this."

Xia Lian looked at Aisha's satellite image. The image at this moment shifted to the junction of frozen soil and paradise, where he saw a "Great Wall."

As the plains and mountains wind up, they are like a barrier, separating them into two worlds.

At a certain section of the Great Wall, a long procession was heading towards the permafrost through the Great Wall. They wrapped themselves in thick robes, held torches, and looked numb.

From the top-down perspective of Xia Lian and others, the long flow of people holding torches formed a long flaming dragon, winding and orderly, which looked very shocking.

Moko was a little confused, "What are you doing? Why are such a large group of people running to the frozen soil?"

"Didn't you notice?" Xia Lian stared at the screen, "Most of the people in this team are old people."

Moko looked at the screen carefully and said, "It seems to be true."

Then, he frowned, "But what does it mean to let the old man go to the frozen soil?"

"Abandon old age."

Oak, who had been silent all this time, said a word, there are micronanites, and his limbs were quickly put together by Aisha, and he has basically recovered now.

"One thousand two hundred years ago, there was a custom in my ethnic group, that is, all elderly people over sixty years old needed to commit suicide, and their bodies were given to livestock for sharing, as a way to contribute to the ethnic group in another way.

This custom is called abandoning the old among you humans, and it was banned after humans brought civilization."

"How could this be possible?" Mo Ke was a little unimaginable. "In that case, the whole society would soon be in chaos. Everyone will grow old. If the young people do not support the old people, but the old people will be abandoned, then people will lose it."

Do you have the motivation to live?"

The rest of the people also frowned slightly. Obviously, this behavior has deeply impacted the ethics of human beings who have entered the interstellar age.

But in fact, ancient humans also did the same thing.

"Productivity determines everything." Xia Lian commented, "Human beings are essentially animals, and the instinct of animals is to reproduce.

The basis of all actions is for reproduction and the continuation of the race. When resources cannot be supplied to an ethnic group and thus affect the continuation of the race, the ethnic group will find ways to reduce resource consumption, and abandoning the elderly is one of the options.

Many animals have similar behaviors of abandoning the elderly, or in other words, supporting the elderly, which is also a sign of the advancement of civilization."

Mercury also spoke at this moment, "Judging from the results, if abandoning the elderly can continue the ethnic group, then war can be avoided, allowing more young people to survive."

"It seems that there are more than just old people in this team?" Karl's voice reminded everyone.

They once again focused their attention on the long dragon in the picture and found that in addition to the old people, there were also some young men and women in the crowd.

"Why are there still young people?" Moko frowned and said.

He looked at Xia Lian and said, "Your Highness, do you know?"

The others couldn't help but look at Xia Lian. During this period, Xia Lian's omniscient and omnipotent posture left a very deep impression on them.

I always feel that I can always find the answer from him.

Xia Lianze said calmly: "There should be some kind of quantitative indicator in this civilization. When there are not enough old people, it will be the turn of young people, maybe the poor, or maybe the bottom of society who have no talent and have no role in society.

"

"Is it true that no one resists?" Aisha couldn't help but ask.

Xia Lian did not reply, but continued to stare at the screen.

Some young people at the end of the team seemed to want to escape, but after running a certain distance, a middle-aged man in a white robe landed from the sky on their escape path.

His palms lit up with light, and he waved heavily at those who were running away. Flames appeared around him, shooting at those who were planning to run away, quickly devouring them, and burning them directly to ashes...

This hand directly shocked the rest of the people who were about to escape, and they returned to the team in silence.

Xia Lian's eyes flashed, "It seems that this is the reason..."
