The scarlet fog swept across the world, and humans became prey amidst the roars of alienated monsters. Former project supervisor Lin Mo accidentally activated the [Infrastructure System], which allowed him to see item levels, unlock defense blueprints, and transform ruins into steel fortresses.
He used corroded steel bars to build traps, relied on rot-resistant potatoes to stabilize the granary, and relied on electromagnetic barriers to block the tide of corpses. He went from being a loner surviving in the warehouse to becoming a leader of a force with a satellite stronghold.
"My base has three layers of defense towers and the moat has to be filled with magma." Lin Mo held a compressed biscuit in his mouth and directed a team of superpowers to reinforce the city wall. "Dare you come to demolish your home? Ask me first if I agree with this red-level cannon."
When the global forces are still struggling for survival, he has used concrete and steel to build a new beacon of human civilization in the apocalypse - but the artillery fire of this lighthouse always hits the intruders who are short-sighted first.
