In the sixties of the twenty-first century, when Yuan Haochen was still a young man, the total population of the earth reached a peak, nearly 9 billion. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

However, since the apocalyptic crisis was exposed, the earth's civilization has begun to fall into the quagmire of chaos. Due to the long-term social unrest and frequent wars, the total global population had plummeted to about 7.5 billion by the time of the Gamma-ray Burst crisis.

Today, this deadly catastrophe has harvested more than 6 billion lives almost overnight! And this figure does not include other plants and animals that live on Earth!

The reality is so cruel that human beings are so small that they are insignificant to the vast universe. Even if the earth's civilization prepared more than a century in advance in order to resist this catastrophe, the outcome was still tragic. It is inconceivable that if the earth's civilization had not discovered this potential crisis in advance, perhaps the earth would have become the grave of all mankind......

According to the post-disaster feedback sent by the Earth Defense Camp, out of a total of 3,012 [Geocentric Cities], only 981 Geocentric Cities can be contacted now, and two-thirds of the Geocentric Cities, with nearly 2.1 billion people, have been buried in the underground world forever.

After the gamma-ray burst, 61.2% of the atmosphere was destroyed, and now the Earth's surface atmospheric pressure is only 40% of the original level, which is equivalent to the original pressure level of the Earth at an altitude of nearly 5,000 meters. To make matters worse, the ozone layer has been completely destroyed by gamma-ray bursts, and the rarep atmosphere is so full of toxic gases that it is impossible to breathe.

Due to the severe damage to the atmosphere, the average temperature of the Earth's surface has also begun to plummet, with temperatures falling below freezing in all regions except around the equator, especially around the North and South Poles, where the lowest temperature has dropped to -118 degrees Celsius.

The temperature of the oceans has also begun to continue to fall, and it has gradually frozen from the North and South Pole regions to the lower latitudes. It is expected that in ten years' time, more than half of the planet's oceans will be covered with thick ice caps......

After reading the above information, Yuan Haochen silently closed the file system and said nothing.

After a long time, Yuan Haochen continued to ask the young scientists who had been waiting by his side.

"Is that all?"

"Yes, Commander-in-Chief, that's all we received!" The young scientist replied cautiously.

"I see, you continue to pay attention to the direction of the earth, and report to me as soon as you have any information!" Yuan Haochen commanded.

"Yes, Commander-in-Chief!" The young scientist hesitated for a moment, then continued, "Well, Commander-in-Chief, we have already contacted the Earth Defense Camp, this is good news, and we will definitely receive more news from the Earth side in the future, so please pay attention to rest." ”

"This, okay, thanks for the concern."

"Then I'll leave first."

"Okay, you go get busy, everyone has worked hard."

Yuan Haochen understood the young scientist's intentions. As soon as the crisis broke out, the entire fleet flew non-stop to the solar system. In the past three years, due to his busy work, Yuan Haochen not only did not sleep, but even the normal rest time could not be guaranteed. Although he didn't feel anything wrong with it, the rest of the staff were secretly worried about his health.

......

The command ship Combined Fleet, as well as the second, sixth, eighth, and ninth Falcon frigates, and the 30th-50th Deep Space Resource Development Fleet, are still flying to Earth at the highest speed, and according to the plan, they will arrive in the solar system in another year.

Originally, after receiving the information from the earth, everyone reduced some of their mental pressure slightly. However, as time passed, everyone's nerves became more and more tense again. Because, after receiving the first message from the Earth Defense Camp, the Interstellar Migration team has not received any other relevant information.

Such a situation is obviously extremely abnormal!!

In the same situation, after the resumption of communication with the Fifth Space City Group, the latest work report will be received almost every day, but in the past period of time, not only has the command ship not received any message from the earth, but even the information sent back to the earth by the command ship has been like a stone in the sea, and there is no response at all.

What exactly is the reason?

Could it be that the Earth Defense camp is too busy to respond?

Or are they in some big trouble again?

As long as you have a complete ultra-long-range communication system, it is not difficult to simply make a reply, and even if the Earth Defense camp becomes anxious and embarrassed after the disaster, it should not even be unable to spare time for simple ultra-long-range communication.

Unless, unless, they don't want to, or can't do ultra-long-distance communication. And there is a clear contradiction between these two reasons.

The logic behind this is incomprehensible: the reluctance of the Earth defense camp to contact the interstellar immigrant camp obviously does not make sense. And since the command ship has received the message from the earth, it means that the earth has restored the ability of ultra-long-range communication.

Therefore, Yuan Haochen deduced that there must have been a problem on the earth side, which caused them to lose the ability to communicate ultra-long distances again.

But now that the horrific gamma-ray bursts are behind us, what else could make the Earth worse?

It seems that the reason behind this will only be revealed when all the rescue teams return to the solar system.

......

Another 11 months have passed, and the long and torturous journey is coming to an end. The second, sixth, eighth, and ninth Falcon frigates, and the 30th-50th deep space resource development fleets are already very close to Earth, and the command ship Combined Fleet will return to Earth in just one month.

"Report to the commander-in-chief, the command ship Combined Fleet has just passed by the asteroid Sedna, and beyond that is the Kuiper belt."

Every once in a while, there will be a special staff member who reports the real-time voyage to Yuan Haochen.

"Okay, I got it!" Yuan Haochen nodded and replied.

Sedna is an outer Neptune object, one of the reddest objects in the solar system, composed mostly of water, methane, nitrogen ice, and torin. Sedna is currently nearly 100 AU from the Sun, 3.5 times the distance between Neptune and the Sun.

The Kuiper Belt is a densely populated hollow disk-like region of the solar system near the ecliptic plane outside Neptune's orbit (about 30 AU from the Sun). The Kuiper Belt contains a number of microstars, fragments of protoplanetary disks from the Sun that have not successfully combined to form planets, resulting in smaller bodies, the largest of which are less than 3,000 kilometers in diameter.

When each of the Space City groups passed through the Kuiper Belt, they ruled out a large number of scientific expeditions and deep-space resource development spacecraft to explore the area.

Yuan knew that when the command ship combined fleet crossed the Kuiper belt, it meant that it was not far from the earth......
