Galaxy World: Star Girl

I am a repeat offender of time travel, and I have taken the system to travel through and accumulate in several spaces, the magic space, the demon space, the alchemy space and the misty world. Now I have entered the galaxy world to start dismantling the scrap ship and building a new ship... But what does this have to do with Star Girl? What is Star Girl? I don't know, the system has no explanation, only the vast stars, and the journey is in the endless sea of ​​stars.
