My Space System in the Siheyuan: Blackmail the Corrupt Elder

Wang Tiedan's transmigration to 1965 Beijing lands him in a desolate Siheyuan courtyard, penniless and starving, just like the body he inherited. This infamous courtyard is a den of vipers: the hypocritical Elder Yi, the brutish Sha Zhu, and the manipulative Qin Huairu, all eyeing each other's scraps. But when a mysterious portable space awakens, instantly restoring his strength and sharpening his 21st-century mind, the game changes. He knows their deepest, darkest secrets. His first target? Blackmail the revered Elder Yi for his ill-gotten fortune. Can one desperate transmigrator outwit an entire courtyard full of human \"beasts\" and climb from starvation to prosperity?
