Age of Echoes

In 2147 AD, physicist Lin Zhao received a warning from four thousand years in the future: Do not build a Dyson sphere, as it will attract "reapers" who will destroy civilization. He and his wife Su Wen secretly launched the "Hermit Project" on the back of the moon to transform humans into quantum dark matter life and sow the seeds of civilization to all parallel time and space. Four thousand years later, Lin Zhao, the last survivor, made a broadcast in the lone ship, only to discover that the "reaper" was actually the sower - what was harvested was the courage of civilization to touch the starlight. The seven thousand three hundred last words of mankind are integrated into the cosmic network, and the three descendants of the Hermit, the Burner, and the Sower continue the same story in the long river of time: existence itself is meaning.
