Transmigrate into a Book Set in the Apocalypse: The Second Male Lead and Supporting Heroine Are Perfect for Each Other

[Apocalypse + Stockpiling + System + Power Fantasy + Sweet Romance + Defying Fate] I wake up to discover I’ve transmigrated into a book, becoming the cannon-fodder female supporting character in an apocalypse novel? The System says I can only die stupidly to help the heroine succeed? I’m not the original host of this quick transmigration! If she dies, she gets another mission. If I die, I’m finished! But this little System actually has a disassemble-and-reassemble function!? Can I take apart a few rice cookers and put them back together as an oven? If I have water and flour, can I reassemble them into bread? Can I learn the blueprints for anything I touch, and even build a gun if I have enough materials? Is this the real-life version of Minecraft? Chen Chuyi carefully carries out her main storyline mission as the cannon-fodder female supporting character, while happily scavenging every day. System! Are you sure you’re a female supporting character System!? And what’s with the mini farm and mini ranch that can be bought with points in your interface? Care to explain? Huh? Isn’t that the second male lead? He’s clearly got an excellent background and plenty of power, but this aloof second male lead is a shameless simp. A simp remains a simp, and in the end, he gets nothing. He’s incredibly powerful in the apocalypse and becomes the leader of the top base, yet he keeps indulging his unrequited love. In the end, he’s gravely injured saving the heroine, only to be abandoned by her! Wait, what?! Why does he seem different from the novel? Why isn’t he following the plot?! Why isn’t he chasing after the heroine and hanging around me instead?! Wait, what?! Is the story turning into one about a pampered little wife doted on by a domineering CEO?!
