Great Qin: From the Start, a Foot Soldier Who Becomes Invincible Through Training

A modern college student transmigrates to the Warring States period after saving someone. He takes over the body of Meng Yi, a young soldier in the Meng family army, and awakens the Iron-Blooded System. Daily training permanently boosts his strength, and he comes with a once-a-year death-defying reprieve. He improves the Qin army's training methods and befriends Nangong Lie and Li Meng. Starting out as a lowly Qin soldier, he campaigns across the land and ultimately unifies the seven kingdoms.
