Infinite Job Transfers Starting from Mechanic

This is the 40,000th year of the Empire's dominance over the Galaxy. The glory of the Great Expedition has long been buried in the dust of history. Su Yu has transmigrated here, opening his eyes to the ruins of a planet in front of him, utterly bewildered. On this planet, there are war machines that stretch for thousands of kilometers, now broken to the extreme, alien beasts whose roars can shatter mountains and rivers, and radiation alien beasts whose mere movement causes further destruction to the surrounding environment— There is everything here, except hope. Whether willingly or not, Su Yu struggled to survive for three years and finally inevitably contracted radiation sickness, seemingly about to become one of the despairing. Until his Profession Panel, capable of infinite job transfers, finally activated. "Ding!" "Detected that the host has met the prerequisites; do you want to take the profession of [Mechanic]?" "Completing this job will allow you to gain profession experience through daily maintenance, recovery, and assembly of mechanical creations, leveling up the profession, and with each upgrade, you receive an enhancement amplification of your physical attributes..." Looking at the pile of broken gun parts in his repair room, an unprecedented light lit up in Su Yu's eyes! Years later, at the core of the Empire, at the highest point of the Terra world, Su Yu, the Mechanic from Ruins Star, Ghost Shadow Blade of Dead Silence Wilderness, Initiator of the Giant God Soldier Project's Restart, Governor of the Shattered Star Region, Master of Mechanical Ascension, Supreme Throne of the Forging World, looked at the torrent of steel gathering below and commanded with a wave of his hand! [Our goal is to make the (second) (crossed out) Empire great again!]
