In the Age of Interstellar Discovery, human civilization was highly prosperous, but it also left behind endless ruins of war and garbage. Lin Yuan, a scavenger living at the bottom of society, searches for valuable scraps in the dangerous space cemetery every day in order to treat his sister's illness. By accident, he obtained a mysterious super upgrade system from the wreckage of a legendary ghost battleship. From then on, any piece of scrap metal in his hands can be turned into a magical weapon that roams the universe. The shabbiest spaceship can be upgraded into the fastest ghost battleship; the most common energy gun can be upgraded into a star-destroying cannon that can shatter stars with one strike. Those who looked down upon him were all trampled under his feet; those who hindered him were all blown into cosmic dust. I, Lin Yuan, am destined to go from being a scavenger to becoming the only king of this sea of stars.
