The Counterattack Guide to the Interstellar Slums

A family of three traveled to the interstellar world, but they were still on a failed frontier planet. They "picked up" an interstellar child as soon as they landed, and then faced an interstellar war and became interstellar refugees. We have no money, no land, no resources, but fortunately our family has a golden finger. Even if the journey is long, she must sing all the way and lead her friends to make a comeback and help the original family reverse its decline. The daughter will then find the heir to the Star Lord as her son-in-law.
