1, 2, 3. End.

Did you feel it?

Earth has existed for 4.6 billion years, while humans have only existed for 5 million years, accounting for about 0.1% of Earth's history. If we compare Earth's history to 24 hours, humans have only existed for 3 seconds.

In the 4.6 billion years of Earth's history, it's hard to imagine that only one human civilization has ever existed.

Time will erase everything.

Perhaps modern human civilization is merely built on the ruins of ancient civilizations, and will ultimately be destined to return to ruins as well.

A basket is full of eggs. One day the basket falls to the ground. What will happen to the eggs inside?

What if we replaced the basket with the Earth and the eggs with humans?

Eggs should be placed in different baskets.

Humans must migrate to other planets to settle.

As early as the beginning of the last century, scientists around the world reached a consensus: humans should migrate to other planets within 100 years to reduce risks.

The survival of civilization is never an easy task. No god will reach out from the clouds to help humanity through calamities; the only thing we can do is try to minimize risks through the knowledge and experience we have.

If humanity can settle on multiple planets, it means that the species as a whole can withstand greater crises and successfully overcome difficulties.

However, given the current level of human technological development, large-scale, feasible interstellar migration will have to wait at least 100 years.

This also means that for the next 100 years, human civilization will be in a state of hanging by a thread and defenseless.

At the request of almost all of the world's top scientists in various fields, governments around the world have reached a rare consensus to launch the "Human Backup Project".

The core of the "Human Backup Plan" is the "Bird's Nest" Mars base.

The "Bird's Nest" Mars base freezes 100,000 human fertilized eggs and 100 million seeds of basic plants, stores DNA maps of known animals on Earth, and houses a digital database of all human civilization, to ensure that if Earth were to suffer a catastrophic disaster one day, the survivors could rebuild a complete human civilization on Earth or elsewhere.

Qiongzhou Island, Wenchang.

On this day, the "First International Multilateral Symposium on Human Rescue to Mars" was officially convened!

Although it was just a small group of people sitting around on small stools, eating sunflower seeds and chatting.

However, since the Director General of the European Space Agency, Bruno Fernandes, was in attendance, the staff simply hung up a banner on an A4 sheet of paper, instantly making it look more upscale and, at least in name, an international conference.

"From a realistic perspective, to achieve Zhang Fan's rescue or return, the first step is to unify our thinking and recognize the arduousness and long-term nature of the Mars rescue mission; the second is to establish a multilateral cooperation mechanism to strengthen organizational leadership and coordination; the third is... um... um..." As the presenter, Liao Changtian, director of the aerospace research office, flipped through several pages of his manuscript, and finally threw it away, saying, "I'm sorry, I can't continue making this up."

“We can’t save him.” Director Liao also sat down and started eating sunflower seeds.

"Mr. Xiao, has our technology regressed to this extent?" ESA Director General Brosnan looked up in bewilderment.

"All the spacecraft on Blue Star were destroyed in the 'New Era,' and all kinds of short-range missiles were exhausted in the defense against meteor showers. Even the only 'Firebird' is still missing." Director Liao continued to explain while eating sunflower seeds.

“But we’re still here,” Brosnan said. “Our talent is still here!”

“We have technical personnel, but we lack the space and equipment. At most, we can build a ‘skyrocket’ to have some fun during holidays.”

"Ah, this..."

"So we should change our approach now. Instead of us going to rescue him, we should let him come back on his own," Xiao Yimin said while cracking sunflower seeds. "Don't forget, although the technology on Earth has been buried in the ocean, Mars still preserves humanity's complete technology."

“Mr. Xiao, you’re right.” Brosnan nodded while cracking sunflower seeds. “If Earth has regressed to the Stone Age, then Mars is the ‘realm of the gods’.”

“Indeed.” Chief Engineer Yang nodded while cracking sunflower seeds. “Mars’ technology is now completely overwhelming that of Earth. It wouldn’t be an exaggeration to say that Zhang Fan is a ‘god’ now.”

"So, ptooey, ptooey, ptooey," Brosnan said, spitting out sunflower seed shells, "our current task is to invite the 'gods' to descend to earth. Pshaw."

“I think there must be quite a few countries in the world that think this way, ptooey, ptooey.” Xiao Yimin said while spitting out sunflower seed shells, “You know why, Mr. Brosnan… ‘A phoenix in the bird’s nest.’”

"Mr. Xiao, pshaw, I appreciate your frankness, pshaw. Perhaps Europe could strengthen its cooperation with your country in Mars exploration..."

"Mr. Brosnan, I completely agree with you, bah, this is a great cause that will lead to a win-win situation through cooperation, bah, bah."

The international multilateral symposium on the first time humans have ever eaten sunflower seeds has come to an end.

Similar meetings are held in many parts of the world. After all, in a post-apocalyptic world, sticking together is essential for survival.

The Presidential Sanctuary in the United States.

The US president was very dissatisfied with the report submitted by NASA Administrator Griffin.

"Is this your answer to me?"

“Mr. President, you must understand that this was originally a top-secret mission, and there’s actually not much we can do…”

I don't want to hear the reasons.

"Mr. President, we have no other choice now..."

"I don't want to hear 'no,' 'can't be done,' or 'there's no way' anymore! I need to find a way to contact Wano Country. I know they have a spaceship on Mars right now..."

Ross, Red Square Fortress, Moscow.

“Mr. Prime Minister, we can’t wait any longer. We must take action, or we will fall behind in this global competition.”

Still no news from Katerina?

"If I may be so blunt, Mr. Prime Minister, General Katerina has been missing for six months. Theoretically speaking, it can be understood that she is actually dead."

“Our country owes her a debt.” The Prime Minister looked out at the sky through the dome, but there was only darkness outside.

“Yes, we should award her the National Hero Medal.” The Defense Minister changed the subject. “Therefore, we should complete her unfinished mission. Now, to allow the Red Empire to rise from the ashes, we must obtain the ‘Phoenix’!”

...

Humanity should thank the group of outstanding scientists of the last century. It was their tireless efforts and almost coercive persistence that left a "spark" for all mankind on Mars.

It left human civilization with a backup and a chance to restart.
