Turn in the Portal and the Whole Country Will Follow Me on an Expedition to the Interstellar Battlefield.

[Submit national flow + science fiction apocalypse + relaxation + alien development] In the interrogation room, Gu Jun was treated as a madman until a fragment of an alien battleship sliced through the steel table like a hot knife cutting through butter. He grinned: "I picked this thing up on a planet that was full of the remains of a god-level civilization. Enough!" Facing the general's shocked eyes, I pointed to the countdown in my head: "There are still 5 hours left. If the country doesn't take action, I will be forcibly teleported back to die!" Running a scrap recycling depot that was about to close down, I accidentally discovered that a broken wooden door that no one wanted in the warehouse was actually a portal leading to an alien battlefield! Here, the armor of Star Destroyers is treated as scrap metal, energy cores can be seen everywhere, and the war garbage of god-level civilizations piles up in mountains. And this door can only be opened by me. A piece of debris picked up made Daxia's technology soar on the spot. I chose to hand it in, and the entire country became my strongest supporter! The recycling bin was heavily guarded, and I became a top secret codenamed 'Spark'. From then on, Daxia began a crazy era of "scavenging" in the universe! Warp drive, energy shield, genetic technology... When the interstellar fleet began to take shape, we deciphered a shocking secret from an alien log: This battlefield is not a ruin. A terrifying "liquidator" civilization is cleaning the battlefield, and their new coordinates are the Earth!
