The sea of stars is like a dream, and the exiles are like shadows. In Xingque's eyes, the universe is a crack with no way back. When he was young, he once glimpsed a legendary starship called the "Shadow Boat" under the ruins of his hometown. It was said to be able to carry the lost to pursue their dreams and return. But the truth about the starship is buried in the hearts and grudges of countless exiles. Xingque wanders around the interstellar border, both a hero and a shadow, wandering between redemption and betrayal. His motivation is not only to find his homeland, but also to explore the boundary between dreams and reality - under the lonely starlight, he dances with his fellow exiles and together they solve the memory puzzle hidden in the starship fragments. The highlight of the story lies in the intertwining of dreams and reality. Every decision made by Xingque flows like a star shadow, affecting the glimmer of fate. Exile is not an escape, but a self-questioning: At the end of the infinite universe, who can protect your dreams?
