The newly built Land Ship... no, it should be called the spaceship, needs real-world testing to uncover any potential issues or areas for improvement.
For the testing of this spaceship, it's not the navy or Land Ship crew coming in, but astronauts sent by the space department.
These astronauts were reassembled by the space department after Chen Xin's superstorm purified the skies of Flame Country, and went through a period of retraining.
Originally, the space department's plan was to send them into space to resume the use of the space station, but there was always a lack of sufficient funding to restart space activities, resulting in the plan not taking place, and the astronauts could only continue training without getting the opportunity to return to space.
But now with the spaceship built by Chen Xin, they finally have the chance to go back to space, allowing humanity to return to the universe.
