Time Travel 1937: I Fought Guerrillas in Songhu

Time travel to 1937, the eve of the Battle of Songhu. Su Wanqing, a modern special operations researcher, woke up with only a piece of wood and three terrified soldiers. A Japanese squadron is approaching. She used lime powder to blind the eyes, used broken glass cloth to trap, and used firecrackers to pretend to be machine guns - in twenty minutes, she killed seventeen Japanese. From then on, there was an additional woman on the Songhu battlefield who specialized in fighting "impossible battles". She taught the defeated soldiers how to fight in the streets, taught the guerrillas how to make explosives, and taught the Eighth Route Army how to fight ambushes. No CP, just doing business, using modern tactics to teach the Japanese how to behave. ——Because some battles must be fought by someone.
