Natural Disasters in the Apocalypse: I Built a Safehouse from Scratch

【Apocalypse + Natural Disasters + Base-Building + Farming + Cutting-Edge Technology + No Rebirth】Disaster strikes, and eternal night descends! I’m an utterly ordinary engineer, yet I awaken the god-tier 【Civilization’s Spark】 System! Analyze anything and generate blueprints! I build an air purifier by hand from scrap while the neighbors are still choking! I use my knowledge to build a water recycling system while they’re still fighting over a mouthful of muddy water! I use technology to build a fortress for the apocalypse while everyone thinks I’m just a lucky shut-in! But as my base grows more and more secure, I uncover more and more secrets. Why did the intercom of the wicked neighbor who died horribly across the hall carry military-grade encrypted signals? Why are there fresh footprints and signs of feeding in an underground shelter that should be empty? And why has my System given me a map pointing to an “unknown biological laboratory”? They think this is just the apocalypse. Only I know this is a damn conspiracy! And I’m the one who’s going to rip it out by the roots!
