The Siheyuan Farm Sign-In System

A twenty-first-century street loafer transmigrated to the Red Star Courtyard and became Su Heping, a traditional Chinese medicine doctor at the steel mill clinic. He activated the Farm Sign-in System, received a Marrow-Cleansing Pill that transformed him inside and out, unlocked the skills of a master physician and a top-tier chef, and stocked his spatial storage with flour, pork, and eggs.
