Lin Yi, a military-industrial engineering doctoral student at the University of Chinese Academy of Sciences, transmigrates into the world of Drawing Sword, only to be press-ganged by Li Yunlong from the start into repairing Hanyang rifles!
He has no System interface. The hardcore military-industrial knowledge in his head is his greatest cheat.
Li Yunlong thinks he's found a college student who can repair rifles. Little does he know the kid will turn around and pull out flying mines, shoulder-fired rocket launchers, and even field artillery!!
