To collect Deep Blue Star's flora and fauna, humanity had dispatched many Mountain-Class Biosphere Spaceships to the planet over the past few years. They then began collecting biosphere samples on a global scale, taking batches of nearly every plant and animal they encountered, or even entire communities outright.
To allow these plants and animals to live aboard the Biosphere Spaceships, humanity had specifically configured the ships' overall environments to match Deep Blue Star's. Deep Blue Star's gravity, soil, air, water sources, microbial environment, and so on—even its lighting conditions had been simulated aboard the ships.
All of this had been prepared long ago. Humanity had always planned to acquire Deep Blue Star's Biosphere Resources; now, they were merely flying Mountain-Class ships directly to Deep Blue Star. This was far more convenient than transporting specimens back and forth between the planet and space with cargo ships. Once in space, they could simply dock with Planet-Class Biosphere Spaceships.
Thus, several hurried years passed, and humanity finally completed the broad collection of Deep Blue Star's plants and animals. It was time to leave.
Humanity's journey to Deep Blue Star had come to an end. Those who were meant to return did so, and after everyone had withdrawn, Lyra entered its launch countdown.
"Farewell, civilization of Deep Blue Star. We hope you will strive to grow stronger, successfully leave your homeworld, step into the vast universe, and pursue your own ideals." At parting, Lyra sent its farewell message.
"Thank you, great Star Alliance. We of Deep Blue Star will never forget your kindness. Thank you for teaching us so much precious knowledge. We will unite and develop our technology. Our goal will be the Sea of Stars. One day, like you, we will embark upon the Great Voyage Road. We, too, will pursue that
