Tang Yin, a reclusive master, lived quietly in the marketplace running a butcher shop. His only daughter, Tang Xiaolei, was humiliated by her fiancé and driven to fall from a building. Casting aside his low‑key life, he pursued the wrongdoers through legal channels, cooperated with the police to expose his former sworn brother Lin Long—who was involved in cross‑border smuggling—and worked with an undercover agent to gather solid evidence, bringing all the underworld forces to justice. In protecting his family, he also restored peace to the city, found warmth and love, and with justice and responsibility, safeguarded the safety of thousands of homes.
