It's Obviously a Star Destroyer Cannon, but You Think It's Magic?

Su Xin traveled to a parallel world and mysteriously revived. All races, new gods, ancient gods, and old rulers all peered at the Ancestral Star. In a fateful awakening trial, Su Xin unlocked the system panel and changed his profession to become a mechanic. But in this world, the mysterious side has risen, and technology has declined. Non-mysterious sides cannot join the Extraordinary Academy. So—— Su Xin was wearing a silver-winged mecha, shooting out laser beams from his chest, and the powerful flamethrower on his hand sprayed out overwhelming flames. Vice President of the Extraordinary Academy: Please explain, what is this? Su Xin scratched his head: This is light and fire magic. When the Ten Thousand Tribes invaded, Su Xin activated the space-based Star Destroyer Cannon and killed several Ten Thousand Tribes gods. The ** of the Extraordinary Academy blew his beard and glared: You said this is magic? As Su Xin's level gets higher and higher... Cthulhu: Your glacial star cannon froze my Dead Sea! King in Yellow: Please stop bombing me! I just want to write a good script! Gods of all races: Destroy! Hurry! This novel and its characters are purely fictitious.
