Wei Niesheng, the second son of the Wei family, has lived in seclusion in a remote courtyard since childhood, neglected and bullied by his entire family. When arrogant servants publicly overstep their bounds and defy their master, he invokes family law to restore discipline, establish rules, and assert his authority. His unwavering resolve shakes the capital, earning praise directly from the Emperor. Using extraordinary intelligence and the principles of clan law, he presents his case and breaks through the impasse, transferring into the eldest branch and establishing an independent lineage. He then impresses the former Chief Minister Feng Yan with his astonishing talents and becomes his disciple. Within the family, he takes charge of its affairs and resolves longstanding problems; beyond it, he calmly debates and contends with powerful ministers. From an abandoned son confined to a remote courtyard, he gradually carves out his own path to prominence among the great families.
