In the New Star Calendar era, the Interstellar Alliance established the "Garden of Eden" system. Since then, humans have been able to stay away from all pain and troubles since birth. Unfortunately, 1% of the population in the eight galaxies still cannot access the "Garden of Eden". They were exiled to the eighth galaxy and became what people call "defective products". At that time, General Lin Jingheng of the Alliance was framed and displaced to the eighth galaxy, where he met Lu Bixing, a young man full of educational ideals. However, life seems calm, but there are undercurrents. The alliance overturned, pirates were rampant, and the two had to lead the "defective products" on an interstellar adventure to uncover layers of mysteries.
