The Last Years of Humankind

It's not a cool novel, it's not time travel, it doesn't have a golden finger, it's about experiencing the magnificent interstellar war from the perspective of the protagonist, an ordinary person... I was neither born in the age of interstellar navigation nor in the golden age of human prosperity. I was born in the era of the unprecedentedly brutal final battle of interstellar war. This war is no longer a simple racial grudge, but a life-and-death struggle for living space and resources. In this struggle, where will the history of mankind go? There is no black technology, no two-way foil, the realistic writing style restores war, welcome to collect!
