Universe For All: I Am Mechanical Species

A moment when eight billion souls, once human, were instantly transported across countless universes. Each person was reborn into a completely unique form, chosen by a powerful, higher-dimensional being for an ultimate challenge: to survive, evolve, and rise as the Master of All Universes. This is the incredible journey of Keon. Once a brilliant human mind, he now finds himself as a rusty, one-inch repair bot, stranded in a forgotten cave beneath a vast, desolate wasteland. He's a mechanic without tools, a warrior without weapons, a king trapped in the body of an insect. But every great master's story begins with a single step, no matter how small. — Description from novelcodex.org
