Lin Ye, a scavenger from the garbage planet, accidentally obtained fragments of the protoss survivors and half a mecha blueprint, and was involved in the human experiment conspiracy of the human federation's "Star Core Project". He started by modifying a simple mecha to survive. He teamed up with retired mecha master Mo, technical genius Xiaoya and other companions. He first escaped from the federal pursuit and left the garbage star, and then joined forces with the Freedom Front to reveal the truth about the star core plan. With the invasion of the Void Predators, Lin Ye awakened his identity as a descendant of the protoss and took the lead in establishing the Interstellar Defense Alliance. He went deep into the protoss home planet to obtain the ultimate mecha technology. He also united with the mechanical race, plant race, and energy race to form the interstellar resistance alliance. At the sacrifice of countless companions, he crushed the ambition of the void reavers to devour the core energy of the universe. In the end, Lin Ye lifted the shackles of the fusion of human and machine souls, established a cosmic civilization symbiosis system, and traveled across the stars as a "civilization fire carrier", turning the star-core mecha from a weapon of war into a bridge of civilization.
