Apocalypse Descends: I'm an Eighth-Level Electrician at Endfield!

[Apocalypse + System + invincible + infrastructure building] A global upheaval wipes out electricity, and the game Arknights: Endfield descends into reality. Humanity becomes food for monsters. Luo Yue, a college student who had just finished wiring up a power line in the game, discovers that he is the world's only “Administrator.” His golden finger is a game System? And his ability is... wiring? While his classmates despair over their phones running low on power, Luo Yue's room is brightly lit, and a movie is playing on his computer. When even the army's artillery can't pierce a monster's defenses, Luo Yue casually lands a basic attack from the game and blasts it to smithereens! What? You want to know why he's so powerful? All Luo Yue can say is that you don't become an eighth-level electrician in Endfield for nothing!
