Return to the Lord from Heaven

Only when humans entered the 800th year of the interstellar era did they truly realize that they could never do without Blue Star. Without the nourishment of the earth, human beings are like dandelions that can never take root, floating in the universe, and eventually even blooming becomes a luxury. So, they want to go home! Even if the earth is already riddled with holes, they still have to set foot on that land again! PS: Short humanities and soft science fiction, not hardcore at all.
