The Machine Age: Another Apocalypse

[A male lead whose combat strength is Schrodinger's cat + a sharp-tongued female lead who's an old-timer on online forums + apocalypse + mechanical race + insect race + slow burn + huge worldbuilding with a multi-threaded plot that demands maximum reading comprehension] Bored with ordinary life, An Ren receives a travel System from "Big Sis." The first world he visits is "Mechanical Star," a planet 500 years after humanity's extinction. [What will the world become after humanity has been gone for 500 years?] "This world is so interesting!" "The insect queen hunts the insect race, the mechanical natural enemy commands the machines, and weak humans gain eternal life, while the mighty me... am going to die." "I don't want to hurt the only ones of my kind, but death hangs over my head like a sword." Redeem myself? No need. To stay alive, I'll be shameless and do whatever it takes! Someone whose story is about to end Bleh~ I'm no good at writing blurbs, and the story isn't much better. I'm just soft and floppy all over~
