Modern shooting-club instructor Lin Wan unexpectedly transmigrates to the Taihang Mountains in the latter stages of the 1937 Battle of Taiyuan, where she becomes a sixteen-year-old orphan. In a war-torn world of incessant bombardment, she leaves behind her comfortable modern life and, armed with superb marksmanship, solid first-aid skills, and wilderness survival knowledge, encounters a scattered Eighth Route Army guerrilla unit and embarks on a fierce, arduous campaign against the Japanese.
From guerrilla warfare in the mountains, short on guns and ammunition, to sabotage and assaults during the Hundred Regiments Offensive; from outwitting the cruel and cunning Japanese major Matsui Ichiro to fighting side by side with Chen Jingming, an officer trained at Whampoa; from leading her squad through desperate battles to expanding her forces into a brigade under her own command, Lin Wan remains on the front lines. She turns farm tools into weapons, compiles first-aid manuals, and teaches villagers to dig tunnels. With modern tactical thinking, she repeatedly tears through Japanese defenses. Amid the flames of war, she also forges bonds of life and death with her comrades, defending the land beneath their feet and their fellow countrymen.
Over eight years of bloody fighting, she witnesses countless sacrifices and shoulders ever greater responsibility. After Japan surrenders, when the chance to return to the modern world presents itself, Lin Wan looks at her devastated homeland, now slowly recovering, and at the comrades and loved one who have fought beside her for years. She resolutely chooses to stay. Taking off her uniform, she devotes herself to building the new China. She goes from war hero to local official, leading the people to reclaim wasteland, build water conservancy projects, and establish schools. She gives all her passion and youth to this land she defended with her life.
This is an epic of resistance against Japan told through the eyes of someone who transmigrated, and a hymn to ordinary people who defended their country with their very bodies in the years of war. With no golden finger to rely on, only resilience and faith, see how Lin Wan is tempered into steel amid the chaos of war.
