Siheyuan: War Hero, Battalion Commander at Nineteen!

When others transmigrate into the Siheyuan, they start by attending a meeting with the three masters of the courtyard.

Zhang Fan is different. He enters the courtyard with three identities: war hero, battalion-level cadre, and deputy chief of the security department. The Jia family tries to claim one of his rooms by pleading a lack of housing, only to discover that this is a hard wall they cannot kick down.

His Reputation Draw System only cares about influence. Teach his coworkers how to train, help capture enemy spies, earn praise from the whole factory, and once his reputation is high enough, he can draw potions, books, and technical blueprints.

Zhang Fan originally just wanted to be a laid-back slacker and enjoy a cozy life with a wife and children, but one case after another keeps pushing him toward meritorious service and promotion.

By the time he marries Lou Xiao'e, even his father-in-law has been trained into an engineering expert using information from the future, quietly accelerating the nation's military-industrial development.
