Apocalypse Arrives: I Become a Powerhouse by Scavenging

Moira Lynch never expected that something like transmigration would happen to her. At first, looking at her vast fortune, with no siblings to fight with and no dramatic relatives to contend with, she thought she had been handed a script for a life of idle leisure. Just as Moira was preparing to embrace this life of ease, she discovered she was wrong. Various natural disasters struck one after another, and without a system, Moira's world went dark. Fortunately, although there was no system, having a spatial dimension was good enough, and Moira began her hoarding mode. She originally thought that this relaxed life was not bad, but the sudden arrival of a game showed Moira a more vibrant and colorful world. Looking at Caelus behind her, ravaged and scarred by natural disasters, Moira felt she had to do something. Thus, Moira became a packrat, treating others' unwanted items as treasures and bringing them back to upgrade her people's equipment: Exoskeleton Mecha, Space Buttons, Flying Devices, spaceships... Many years later, when Caelus officially integrated with the interstellar community and the natural disasters were resolved, the people of Caelus once again lived peaceful and serene lives. And all of this was thanks to one person—Moira Lynch. — Description from novelcodex.org
