The End of the World: from Wasteland Scavenger to Military and Industrial Overlord of the Universe

[Apocalypse + Zombies + Zerg + Military Industry + Building Power + Decisive Killing + Base Construction] Travel to the end of the natural disaster more than thirty years later. The Tyranids are ravaging the world. Human industrial systems were destroyed and metal deposits were occupied. As long as the survivors try to rebuild the industrial base, they will immediately attract a wave of Zerg, Orcs, and zombies to cleanse them wildly. A wasteland that is extremely lacking in weapons and equipment. Even a broken revolver can become a life-saving artifact that survivors frantically scramble for. Fine. Lin Hao, who has awakened the [Scrap Refurbishment] system, can renovate and recast military-grade military equipment by collecting crystals and scraps. The dazzling life of a post-apocalyptic scavenger and wasteland garbage man officially begins! From pistols, rifles, machine guns, to tanks, aircraft, battleships... Relying on the garbage man Lin Hao, mankind has rearmed its teeth and spread the war into deep space. Countless civilizations and monuments that were exterminated by the Zerg were discovered—— "Sir Lin Hao, we found a large number of heavy armor parts on Mars..." "Sir Lin Hao, the wreckage of the orbital gun was excavated on Pluto..." "Sir Lin Hao, the ruins of the Star Destroyer Fleet were detected at the edge of the galaxy..." … The Terran Zerg didn't even think about it until the moment they were completely wiped out—— Isn't it true that only Zerg can devour civilized creatures, fuse genes, continuously evolve, and proliferate infinitely? How can the backward civilization of the earth be able to infinitely copy even the technologically advanced starships and mechas? We had just destroyed one Star Destroyer, why did ten more appear in such an instant? Not only do they look brand new from the factory, but they also look exactly the same?
