Tombstone of Civilization: I Press the Fast Forward Button for All Mankind

A countdown burned on my retinas: seven years, three months and fourteen days. Seven years later, cosmic scavengers called "Sweepers" will arrive on Earth and erase all traces of human existence like words on a blackboard. But I, a "former genius" whose achievements were stolen by my mentor and who made a living by delivering food, had a grave buried in my mind - the Archives of Civilization Fire. There lies the entire legacy of 137 extinct civilizations, and I am the only gravekeeper. When the National Security Strategy's gun was pointed at me, I didn't explain. I just took out a piece of junk made of scrap parts from the takeout box. "It's called a local gravitational field generator," I said, "a kindergarten toy for a warp drive. I can make this coin float against gravity for a second—at the cost of possibly folding us all into two dimensions." The moment the coin floated, Secret Service Director Chen Shanhe's pupils shrank to pinpoints. Because he knew that his son, who had just entered the special training camp at the age of sixteen, would be the first to face the butcher's knife in the starry sky seven years later. "Gamble," I stared at him. "Give me the highest authority. I will dig up the graves of 137 civilizations and take out all the technology inside." "Seven years later, I want the sweepers to see no longer a lamb to be slaughtered——" "It's a steel hedgehog with black technology spikes all over its body." Now, the countdown starts beating: 7 years, 3 months, 14 days, 06 hours, 49 minutes and 37 seconds... And my first mission is not to build a spaceship. It is to uncover those "one's own people" whose brains have been corroded by the starry sky and lurk within human beings.
