From the War to Resist US Aggression and Aid Korea to the Steel Mill: Life in a Beijing Courtyard

Modern-day Yi Ping'an transmigrates by accident and becomes the long-lost son of Yi Zhonghai, the First Master of the courtyard compound. He awakens a skill proficiency System. Just as the War to Resist U.S. Aggression and Aid Korea breaks out, he heads to the battlefield with his System, tempering himself into steel. After leaving the army in 1954, he joins the security department at the Beiping Steel Rolling Mill and is assigned to Courtyard No. 95, where he unexpectedly reunites with his biological father, Yi Zhonghai. Faced with the beastly neighbors in the courtyard, he draws on the decisiveness he forged on the battlefield and the strength granted by his System to deal with them one by one and keep his family safe. From battlefield hero to pillar of the courtyard, he puts down roots amid the tides of the times, gets married, raises children, and lives a life all his own.
