Playing Games in the Interstellar in Order to Survive

Star calendar year 3285 is another ordinary year. It should be like this, but who would have thought that the world would be different from this day on. "Mad, who knows where that damn Bai Yuan's family lives? I have a bunch of fun and wonderful gadgets that I want to give to him!" Looking at these comments, Bai Yuan said that if there were no changes after time travel, wouldn't it be a waste of time~ But can you tell me who the person who appears in the game is? Is this who is supposed to be there? Do this for me and do that? Is this still the interstellar era?
