Siheyuan: From the Start, I Took on Every Villain in the Courtyard

Everyone in the siheyuan pretends to be righteous, while secretly preying on families without heirs, stealing grain coupons, and plotting murder. When Shen Jianye arrives in this world, he refuses to play along. A Marrow-Cleansing Pill strengthens his body, and the System rewards him with practical skills. With a strong body and unshakable confidence, he writes denunciation letters and reports them to the Public Security Bureau, exposing the entire courtyard's schemes. Even when the villains band together, they can't escape justice. He settles every blood debt, one by one, without relying on fake affection. His life is steady, and his revenge is never left unfinished.
