Doomsday Rebirth: My Base Can Be Upgraded Without Limit

[Reborn + System + apocalypse + extreme hoarding + obsessive builder + ruthless and decisive + multiple heroines + advanced technology] Betrayed by his brother and set up by a bleeding-heart do-gooder, Lin Yuan, humanity’s last leader, closed his eyes in hatred amid the zombie horde. In a single moment, he was reborn three months before the apocalypse broke out! Looking at the tens of billions in his account, money his enemies from his past life had used to make their fortunes, Lin Yuan smiled. What’s yours is mine! Bound to the [Seeds of Civilization] System, he had unlimited storage space from the start! In this life, he would stockpile supplies and save no one! Ruthless and decisive, he would look out for himself alone! When disaster struck and the world descended into chaos, with everyone fighting over a piece of bread, Lin Yuan was lounging in an impregnable doomsday fortress, eating steak and drinking red wine. While others ate dirt, he ate meat. While others hid, he built a city! He advanced technology, built an army, recruited talent, and absorbed rival factions! From one man’s safe house to the only mechanical empire in the world! By the time his old enemies knelt outside his city and the truth of the world came to light, Lin Yuan had already risen to the pinnacle of civilization, with the entire wasteland at his feet!
