Mecha: Rising from the Scrapyard

On the day of the Holy Pool's awakening, Renn was judged to be a waste with zero-level magic power. His fiancée broke off the engagement on the spot, and the family elders teamed up to abolish his inheritance rights, and sent him to the No. 13 Scrapyard full of magic radiation on a cold rainy night. Everyone is waiting for him to rot in the garbage. But they didn't know that what he awakened was not the waste form, but the [Omniscient Eye] that had only appeared twice in ten thousand years - a terrifying computing power that could see through all energy flows and deconstruct magic and machinery into precise data. Deep in the scrapyard, he awakened the remnant soul of an ancient mechanical dragon that had been sleeping for thousands of years, and used scrap metal to build the mecha "Scavenger" with his own hands. When the genius mages in the imperial capital were still showing off forbidden spells, he used steel and gears to teach them what dimensionality reduction strikes were. "Scrap metal also has dignity." This is a story about a mortal using steel and will to redefine the dignity of scrap metal in an era of decayed magic.
