The Dajing Dynasty has been at peace for three hundred years. The aristocratic families in the court have controlled the power. The undercurrents of local vassals are surging. The barbarians in the north have been knocking on the gate for years. The surviving tribes in the west are looking for opportunities to restore the country. Internal and external troubles are intertwined. Under the skin of the prosperous times, it is already in turmoil. Young Shen Mo was born into a poor family in the south of the Yangtze River. His father was framed by an aristocratic family and died unjustly, and his mother died of an illness due to overwork. He lived in a ruined temple since he was a child and made a living by copying books. He suffered all the hardships of the world and the bullying of the powerful. He has a family blood feud and the ambition to help the world and bring peace to the people. He studied military strategies and practiced close-quarters halberds diligently. His black iron halberd hides the unyielding pride of a boy from a poor family. In order to clear his father's grievance and find a way out, Shen Mo abandoned his literary career and joined the army. However, due to his poor family background and helplessness, he was reduced to the lowest rank soldier in the military camp. He was squeezed out, framed, and plotted by soldiers from aristocratic families, and was killed several times. He worked step by step, endured and lurked, and relied on his extraordinary resourcefulness, iron-blooded courage, and extraordinary martial arts to fight his way through the mountains of corpses and seas of blood at the northern border. He grew from a pawn who was trampled on by others to a young general guarding one side. In troubled times, he was deeply involved in the whirlpool of court intrigues and feudal princes' rebellion. While resisting the iron hooves of foreigners, he was investigating old family cases, tearing apart the family's corruption network, smashing the feudal prince's conspiracy, subduing the forces of the surviving clan in the Western Region, getting to know life-and-death brothers, confidants, and beauties. He also encountered betrayal, calculations, and life-or-death separations. He guarded the border, quelled civil strife, purged traitors and pacified the common people. With his humble background, he broke down the class barriers of aristocratic families. With his military exploits and loyalty, he shook up the centuries-old imperial court structure of Dajing. From a humble young man in the south of the Yangtze River, to an iron-blooded general in the north, to the pillar of the auxiliary country who decided to make peace and stability, and finally to wear a python robe, take charge of the military, and be a noble lord, guarding thousands of miles of rivers and mountains, creating an eternal legend.
