You Promised to Ascend Mechanically, but Your Body Will Explode to the Stars?

I, Link, a wasteland orphan who can't even afford a basic prosthetic body, am bound to the stingiest system in history. It doesn't send artifacts or tasks. It only whispers in my ear: "Host, the rusty steel pipe on your left hand side can actually be optimized to vibranium quality." So, when others spent money to modify cool mechas, I picked up the trash and started my journey of "magic modification". Until that day, the fleet of the universe-level consortium came to the city, and I walked out of the ruins carrying the steel pipe that had been optimized 10,000 times. A frightened voice suddenly sounded across the channel: "Warning! Unknown law weapon detected! All energy shields... Are being 'optimized' into scrap metal!"
