Rebirth at the End of the World: My Base Can Be Upgraded Infinitely

[Rebirth + System + Apocalypse + Extreme Stockpiling + Infrastructure Maniac + Decisive Killing + Multiple Female Protagonists + Black Technology] Betrayed by his brothers and framed by the Virgin, Lin Yuan, the last leader of mankind, closed his eyes with hatred in the tide of corpses. Once reborn, he went back to three months before the apocalypse broke out! Lin Yuan smiled when he looked at the tens of billions of dollars in his account that his former enemy had made. What's yours is mine! Bind the [Civilization Fire] system and have unlimited space at the beginning! In this life, I only stock up on goods and don't save people! Kill decisively, just for yourself! When a natural disaster struck, the world fell into chaos, and everyone struggled for a piece of bread, Lin Yuan was lying in the impregnable fortress of doom, eating steak and drinking red wine. While others eat dirt, I eat meat; while others hide, I build cities! Climb technology, build an army, recruit talents, and gain power! From one person's safe house to the world's only mechanical kingdom! When the former enemies knelt before the city, when the truth of the world was revealed, Lin Yuan was already standing on the top of civilization, with the entire wasteland world at his feet!
