I’m Building Railways in the Apocalypse

[This story has been revised through Chapter 63. Chapter 64 onward has not been revised yet, and some content is repeated. Please purchase with caution.] [Many chapters have been almost entirely rewritten, so revisions are slow. Quite a few character details and settings have changed, and the revised version differs greatly from pirated copies.] In her previous life, after the apocalypse began, Lin Ran was an ordinary person. She earned a meager amount of food by doing hard labor for a road construction crew, barely managing to support herself. Her former family mocked her, unscrupulous ability users bullied her, and in the second year of the apocalypse, she died trying to save someone. Reborn three minutes before the apocalypse, the first thing she did was find a zombie with an ability and get it to bite her, hoping to awaken an ability of her own. This time, she would become a respectable person capable of protecting herself. Later, she discovered that the bracelet her sanctimonious classmate had taken from her in her previous life came with a pocket dimension. [Ding! Bind with me to activate Saint Mode. For every 100 Gratitude Points you earn from other people, your space will expand by one square meter!] Lin Ran replied coldly, "I won't bind, activate, or play the saint." [All right, then. Activate Railway Construction Mode. For every 100 meters of railway you build, your space will expand by one square meter.] And so Lin Ran was forced to embark on a career building railways. In the apocalypse, rampant mutant plants destroyed roads, making transportation a huge problem. The bases were completely cut off from one another. Then one person appeared. The railways she built couldn't be damaged by mutant plants, and zombies wouldn't go near them. They were absolutely safe and reliable. From then on, the clattering green passenger trains, puffing steam as they rolled along, became the sight that gave people the greatest sense of security. Wherever the railway reached and the trains could go became a place where civilization could be rebuilt. Theme: Rebuilding after the apocalypse starts with building roads.
