Mechanic on a Steam Treasure Hunter

Traveling to the age of steam islands, Li Ang brought a "Mechanical Maintenance Manual" [The power core wear degree is 33%, please replace the sealing ring] [The tail rudder steam pipe is slightly cracked and materials are missing (titanium alloy*1, tungsten steel*3)] [Observed the complete structure of the lost technology "Wind Spirit Bead"] [Can be upgraded to "Old Windweaver Power Core"] Without a certificate and no house, Li Ang could only squeeze in the basement to repair machines to make a living. He looked at the increasingly outrageous golden finger in front of him. "I just want to be a low-key machine repairman, get a certificate, and earn a living." Unfortunately, it backfired. The church's "Psalm Armor" had a power core that no one could repair for ten years, so the Archbishop sent an aerial rider overnight to invite him. The blueprints of the Imperial Military Department's "Dawn-class" strategic airship were so altered in his hands that even the original designer called it a miracle. Even the old academics of the royal family were chasing after his airship, holding the "Difference Engine Construction Diagram" that had been lost for centuries. Many years later, when Li Ang stood in the floating fortress he built, he couldn't help but sigh, "As expected, I still prefer building things than repairing them." "Li Ang! My tail rudder is stuck, come and fix it!" Li Ang activated the "Sunfury" plasma main gun on the bow of the ship that he designed himself. "Repair what? Direct fire coverage." From a low-level gangster machine repairman to the recognized "god of all weapons" in this airspace. Li Ang said, "I really didn't do anything, just repairing gears and raising squirrels every day, and it ended up like this before I knew it."
