System Blessing: I Will Be the King Alone in the Last Days

In 2299, a silicon-based catastrophe broke out, iron-eating insects devoured the world's metals, "mechanical variants" that were half-mechanical and half-biological were rampant, and human civilization collapsed into ruins. Luo Zheng was reborn 10 days before the disaster and was bound to the "Hunting Evolution System". The only rule is: walk alone, hunt, and evolve. In his previous life, he died due to the betrayal of his teammates. In this life, he only believes in himself—— There are no teammates, no weaknesses, and no cheap emotional bonds. Compressed cookies? He stocked up enough to last ten years. A safe fortress? He chose the depths of the ceramic ruins that Ironeater hated most. Arms? Ceramic knives, stone spears, and even reassembled mechanical remains are good things as long as they can transform into killing weapons. System releases tasks? Kill ten primary mechanical variants? Too simple. Unlock the "Machine Affinity" power? Can you control drones in ruins? It's just a hunting tool. Encountered scavengers robbing resources? Then let them become the rations of the mechanical mutants. From the iron ruins to the iron-eating insect nest, from the primary hunter to the mechanical master—— In Luo Zheng's dictionary, there are only "survive" and "become stronger". As for the warmth and bond in the apocalypse? "That's garbage that will kill you faster." (No heroine, no team, purely solo. Let's see how the lone wolf uses the system and reborn memory to fight his way through the silicon-based apocalypse.)
