In the troubled times of the late Ming Dynasty, soldier Li Jianan traveled through time and activated the "Super Copying System", which can copy materials infinitely. He first saved his family and killed the bandits, quickly accumulated wealth and military strength by virtue of his copying ability, and was promoted to an officer. Since then, he has repeatedly made military exploits, resisting Japanese pirates, suppressing rogue bandits, and resisting the Qing army, and gradually rose to the rank of Qianhu and count. He maneuvered between officialdom and the battlefield, using the power of replication to build an iron army and reverse the situation of the war, and was highly regarded by Chongzhen. In the end, internal and external threats were put down, and he became the pillar of the country and protected the mountains and rivers of the Ming Dynasty.
