In the thirty-fourth year of the Daxia era, Prince Jin's household was framed by Zhou Yong and Zhang Congshan. The entire family was sentenced to death for treason. Fourteen-year-old Lady Lin Nianyi escaped by a hair's breadth and went into hiding under an assumed name, carrying a blood feud with her.
She gathered the remnants of the Blazing Flame Army and joined forces with the martial world, laying her plans step by step in Jiangnan. She exposed the Netherworld Sect's illicit pill-making scheme, uncovered conclusive evidence of collusion between corrupt officials and evil forces, and destroyed the heretical sect's main headquarters. She solved a string of interconnected cases involving the salt trade, grain transport, and stolen maps, and rebuilt the intelligence network of the Heavenly Secret Pavilion.
Along the way, she gathered loyal and courageous allies and exposed the mastermind's plot to manipulate the imperial court and plunge the realm into chaos. At last, armed with irrefutable evidence, she stormed the Golden Throne Hall and exposed Zhang Congshan's crimes, clearing the names of Prince Jin's household and the Blazing Flame Army.
From a fugitive orphan to the master of the Heavenly Secret Pavilion, Lin Nianyi swore to "stay true to herself and protect the people." Amid flashing blades and clashing steel, she upheld justice and carried on the legacy of the loyal and virtuous.
