In the distant interstellar era, the "Galaxy Alliance" controlled the power and order of the galaxy. Five young people from the bottom with different circumstances met through an accidental freight accident and embarked on an interstellar journey full of intrigue, collusion of interests and technological crises. With personal growth and teamwork, they continue to break through themselves, dismantle the corrupt alliance system, and respond to crises with humor in multi-line parallel adventure missions. They eventually become the saviors who lead the reform of the galaxy and ignite the hope of the weak. The three volumes of the book are compact and full of ups and downs, integrating humor, friendship and growth, depicting how teenagers on the edge of the interstellar world reverse their fate and write legends.
