Also known as: "A Journey to Another World Begins with a Brain Swap" and "Crisis! A Broken Mech from the Start"
Lu Ye, an ordinary wage earner, transmigrates into the body of a mech pilot who has been drifting alone in planetary orbit for 8,000 years. He gets the mech he has always dreamed of, only to have his brain swapped out on day one. After escaping the danger of his mech falling into a star, he plans to reach the pinnacle of life with pure technology far beyond that of the natives. Then he discovers this is a world of swords and magic, where modern technology is useless. Every native he meets has a wild imagination: they either mistake Lu Ye for an evil god or a powerful demon. Lu Ye is constantly fretting over how to make himself look strong.
Lu Ye: "I'm freaking out. I'm stuck in a pile of scrap with no magic resistance. How am I supposed to deal with magical threats? Waiting for answers, urgent!"
Cute, busty priestess of the Dark Moon Elves: "You are the savior of our people!"
New leader of the Chaos Demons: "Great one, please let our people follow you into battle!"
Cat-eared female thief: "You're sure you won't lust after my body and eat me?"
Lu Ye: "..."
He planned to quietly build up his strength, but a stone tablet from 8,000 years ago constantly reminds Lu Ye of the deadly threat this world holds for him.
