[No clichés, no sleazy writing, no harem, full of attitude] This story takes place after the events of "Through the Vastness." As Earth enters an irreversible warming phase, becoming uninhabitable, humanity launches the "Dandelion Project," which digitizes all of human civilization, compressing, encoding, and modulating it into radio signals, broadcasting them into the depths of space. Hoping to encounter a technologically advanced civilization, they would demodulate, decode, and decompress the received signal, then transfer the information to a new medium, thus continuing human civilization—even a fragment of it. Unknown how long ago, at the edge of the universe, a fragmented civilization and a fragmented people yearn for wholeness. A young man can rescue a dejected man from jumping into a river due to layoffs, stop a heartbroken woman from hanging herself, persuade an elderly man abandoned by his children from taking that final leap, and even help a child lost in a chaotic street find their parents, yet they know nothing of their own origins. He wants to search, they all want to search, searching in the vast void of the universe. Where have past civilizations, past loved ones, gone? How can they find them? What dangers will they encounter? What whirlpools will they be drawn into?

In February 2021, the concept of "low-altitude economy" was incorporated into the national plan for the first time. Supported by multiple policies, including airspace, economic, and industry policies, my country's low-altitude economy is finally entering a golden age of rapid development... However, Sun Qin and Yuan Zhiliang have been working hard for five years to achieve this moment. They once worked for well-known aircraft manufacturers and vehicle manufacturers, respectively, with stable incomes and social status. However, their optimism about the low-altitude economy and the future of three-dimensional transportation led them to resign and start their own businesses. The "Decepticons" and "Autobots" began their journeys to the same destination, having weathered many setbacks before finally embracing the opportunity presented by the era...

Thick fog hangs over the airport, international flights are delayed, and an ace agent from the Space Survey Agency navigates a polar vortex. Enduring severe turbulence, his passport expires, and his luggage is lost, he finds his own body on the baggage carousel, clutching the pendant of his ex-girlfriend, whom he had just met thousands of miles away in New York City. On the tarmac, at the airport control tower, in the cockpit, in the first-class cabin, even on communications satellites... Mysteries unfold in every corner of the sky and on the ground. Who is behind this? Under the vast sky, when will the mystery lift?

Development is an eternal pursuit for humanity, but at what cost? It certainly cannot be the Earth itself, for it is humanity's shared and only home. What does development require? Energy. However, our supply chains in traditional energy are somewhat fragile. Whether protecting humanity's home or ensuring our own energy security, developing new energy and achieving carbon neutrality is the only path forward, a path that has been elevated to national strategy. Our young new energy entrepreneurs are continuously achieving technological breakthroughs and commercial success along this path, driving the development of the global new energy industry.

What if one day, every spacecraft in outer space around Earth—whether it's China's Changgong Space Station or the US SpaceLink satellite constellation—were destroyed, their debris forever circling the Earth, like the gnarled rope tightly wrapped around a prisoner's neck on a gallows? Would you still be able to breathe? Could you escape unscathed? Could such a scenario ever happen? If it did, would it be a blessing or a curse? Would you choose to be imprisoned in the heavens, or break free? Waiting online, it's urgent.

The ancients determined the seasons based on the direction pointed by the Big Dipper. Today, we have a new Big Dipper, spanning the skies above us, becoming our "eye in the sky," safeguarding national security and serving society and the people's well-being. This is the BeiDou satellite navigation system, independently developed and built by my country. The novel depicts the arduous and magnificent construction process and the growth of each individual along the way. Like the Big Dipper, they shine like a starry sky.

In 2048, the Earth's climate will officially enter an irreversible warming phase, and mankind will have to accelerate the exploration of the continuation of civilization.

It is too difficult to move the Earth to other galaxies, and it is impossible to solve the problem of “single point of failure”, so we can only broaden the radius of human activities through the development of aerospace science and technology within a limited period of time, and at the same time, we can prolong the survival cycle by means of the development of biotechnology and intelligent science and technology.

Seeking the continuation of civilization in the vast universe has become the highest goal of the whole, under which every individual has to make his own choice.
