Alien Epic 2035

When people realize that this universe has more than just our space and time, many things have silently changed. Facing the depletion of resources and the expansion of people's ambitions, it seems inevitable to launch a war on the other side of time and space. When people really launched this war that spanned time and space, they found that no one could fully control the direction of this war; when people finally realized that they could no longer be alone, the great, absurd, selfish, smart but self-inflicted characters took turns to be on the stage of the war, but no one could stay at the end; when at the end of the story, the giant wheel of history slowly rolled over, how many people could smile with relief at this long war. (Maybe this is just a world of events with trends dictated by the Book of Answers)
