War of Resistance: Start as an Engineer, a Tyrant on the Battlefield

In 1937, the Battle of Songhu ended. The Japs threatened to destroy our Dragon Kingdom in March, and their troops were approaching Jinling, the capital. At this time of crisis, Su Wu accidentally traveled through time and awakened the universal role-playing system. "Playing as Gruno, you can invent the MG42 universal machine gun." "Playing as Edwin Bagsley, you can research and develop the M1 Carbine." "Playing as William Mauser or Peter Paul Mauser, you can develop a 98K sniper rifle." "Playing as Hulek, you can develop the Czech light machine gun." "Play as John Thomson and invent the Chicago Printer and the Thomson submachine gun." "Playing as a Watervliet technician, you can develop the M-19 mortar." "Playing as Nie Peizhang, you can invent heartless cannons." ..... At the foot of Mount Fuji, Su Wu sat calmly on a wooden chair and looked at the little Japanese Emperor: "I heard that you want to destroy our Dragon Kingdom in March?"
