Time will slowly fade away memory, and the past is like the wind, whistling past everyone.

Time will never stop, and a lot passes by people accidentally during this thought.

Some people say that time will never allow us to make too much souvenirs about the past. Just like all the magnificent events, the departure of the Second Space City Group has gradually faded into the hearts of those who stayed on Earth.

However, when people look up at the stars, they often think of those relatives and friends who have been away from them, and then they will feel sad, and then they will continue their lives and see their own scenery.

In May 2122 AD, 143 years have passed since the first year of the crisis, 1969.

Durunik fulfilled his promise and within 8 years, he led the [Former Interstellar Exploration Alliance] who left behind on Earth to complete the construction mission of the Third Space City Group.

The Third Space City Group contains a total of 370 space cities, a population of about 110 million, a deep space resource development fleet, and 1,400 escort warships. So far, the interstellar immigration camp has a total of 1,071 space cities, a population of about 350 million, a 104 deep space resource development fleet, and nearly 4,000 escort warships.

At the same time, the construction progress of geocentric cities has also exceeded the target upper limit. A total of 2,600 [geocentric cities] have been built (the original construction target is 2,000), with a total of 2.7 billion people living in underground cities, exceeding the original target by 25%.

There is a problem of upper capacity in underground cities, so the construction of [Geocentric City] is actually coming to an end, and it is unlikely that a large-scale new geocentric city will be built in the future. However, nearly 5 billion people are still left behind in the ground world.

Due to the implementation of special policies for more than 40 years, while a large number of young people have moved underground or space, a large number of aging populations in geocentric cities have shifted outward. In addition, some left-behind young people have grown old while waiting for time. Therefore, the population structure of the left-behind world on the ground has shown a sharp aging and negative growth trend.

It is particularly important to mention that due to the impact of the end-of-day crisis, in the turbulent and frequent wars, more and more young couples choose to have less or not have children. Therefore, the birth rate of the population has also been greatly affected. In the past 50 years, the total population of the earth has dropped sharply from 9 billion to 8 billion.

This is certainly not a good sign, but it has indeed relieved the pressure from governments to a certain extent, so governments also turned a blind eye to it and let it go.

To sum up, 70% of the 5 billion people left behind in the ground world are elderly people, and only 30% of the population under 50 years old, but this also means that there are still 1.5 billion target populations that cannot be properly resettled.

In the fifth year after the Third Space City Group left the solar system, the First Space City Group was about 1 light-year from the Sand Star in the Alpha Centaurus, and they had entered the stage of slowing down. The Second Space City Group where the Original Naichen is located has just entered the second year of stable flight, about 2.8 light-years away from the Sand Star.

On this day, in the highest administrative district of Central Space City, where the federal government is located, Yuan Shichen received an email from the earth. The email was sent to him more than a year ago.

At this moment, Yuan Shichen was sitting alone in the office. He turned on the email system and an old but extremely familiar face appeared on the display screen.

It is his friend Durunik. He is nearly 90 years old, and his wrinkled face is like a sand bucket of time, and he can clearly see the traces of the wind and rain of the years. In the slightly sunken eye sockets, a pair of dark blue eyes can still see vitality and spirit.

Before Durunik could speak, Yuan Shichen sighed first. Durunik was only a few years older than him, but it formed an extremely sharp contrast with himself. It really made him feel astonished as if he was as bright as black hair and snow.

"Yi Chen, you're okay." Durunik's slightly low voice rang, "Old habit, today I will tell you a bad news and a good news!"

"I know you are used to listening to bad news first. Just a few days ago, the Commander-in-Chief passed away," Durunik made a prayer move and continued, "When the Commander-in-Chief left, he told us all, including you. The Commander-in-Chief said he was very happy because he had lived in his 100s and when he left, the end-of-day crisis had not yet erupted, which means that the earth's civilization has made another precious time."

Even though this news surprised Yuan Shichen, it seemed reasonable. Including the death of Dr. Mingqi a few years ago, although he felt regretful, he could only sigh secretly and could not change anything.

"The Commander-in-Chief hopes that we will not be sad. He has seen through life and death. There is no regret in leaving him this time."

Durunik was silent for a while and continued, "It's true, I can especially understand the mood of the Commander-in-Chief. Life is short, and I don't think I will have any regrets when I leave this world. But I still hope to live a few more years, and I hope to see more space cities full of hopes to leave the solar system."

"Okay, let's talk about the good news next." Durunik changed his tone and continued to say slowly, "You know, the construction of [Geocentric World] has long exceeded the load of the earth. Therefore, governments around the world have gradually stopped the construction of [Geocentric City] and shifted the focus of construction to space cities."

"So, the construction progress of Space City is expected to accelerate further. Unfortunately, most of the labor force on Earth has been transferred to underground cities. Otherwise, the construction of Space City will be faster." Durunik said with a smile, "Haha~, no matter what, in another two years, the Fourth Space City Group will be expected to fly out of the solar system. I believe I can see that day!"

"I really smile so slutty when I'm old," Yuan Shichen said sadly as he looked at Durunik's wrinkled smiley face.

"In the end, I want to say one more thing."

Speaking of this, Durunik's face suddenly became gloomy.

"I believe you have also realized that by comparing the trajectory of star w over the past century, we have found that the rotation axis of star w is more accurately aligned with the earth."

"This is really a great irony. Is the Earth civilization the abandoned child of the universe? Is the universe deliberately trying to kill us? Star w is like a terrifying sniper rifle aiming at the earth. The earth is completely in the center of the strong gamma-ray explosion particle beam without any tilt." Durunik said angrily.

"Why is this happening? I have a strong premonition that the earth has been accurately locked, and the doomsday may not be far away."

After saying this, Durunik fell silent with a helpless look on his face.
