[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?
