The reborn Jiang Yansheng carries his memories of the past life, returning to the time before the old case of Hanchuan broke out. Relying on his internal affairs authority, Pei Zhuxiao embezzled spiritual marrow, framed his father, and suppressed humble families. Forsaking private brawls, Jiang Yansheng unites with Lin Zhaowei and others, seals and rubs evidence, and builds a complete chain of evidence, applying for the Heavenly Punishment Sword Trial according to the old rules of the sect. Through ten days of special training, he masters the three-path ink breath circulation in a locked-meridian environment, breaks through three formations, opens the internal affairs general ledger in public, overturns the old case, clears his father's name, and drives the sect to revise the rules for resource allocation. Ultimately, he lays down his obsession with revenge, returns to Hanchuan to impart teachings, and uses his sword to guard the foundation of fair cultivation for humble families.
