Are Mechanics Weak? From the Start, I Transform the Campus Beauty into an Android

Ye Zhen was incredibly lucky: he got hit by a hundred-ton stroke of fortune and, unfortunately, transmigrated to a parallel world! Ferocious beasts ran rampant in this world, foreign races wreaked havoc, and the wilderness was full of dungeons and secret realms. Humanity was on the brink of ruin! Fortunately, there was still a way forward. Humans could awaken as various classes and level up and grow stronger by killing monsters. From the start, he changed class into a Mechanic, widely considered the most useless and weakest class of all! Luckily, he awakened the God-Tier Class System. His Mechanic class evolved into the one and only god-tier class, Mechanical Overlord, which could extract the blueprints of any mechanical creation from the Myriad Worlds! He drew the blueprints for Androids 17 and 18 from the start, turning the useless campus belle into an android! After that, all kinds of mechanical creations appeared one after another: Androids, Skynet, Genos, the Digimon series, the Transformers series, artificial monsters, artificial Ultramen... S-rank class holders? SSS-rank class holders? Hidden classes? I don't care who you are. In the face of my mechanical creations and modified beings, you're utterly powerless! As god-tier monsters from beyond the stars descended and the world stood on the brink of its end, Ye Zhen silently summoned his latest mechanical creation: Artificial Heavenly Emperor, Huang!
