A historical political-strategy drama set in the Great Jing Dynasty. The imperial court is rotten, powerful aristocratic families monopolize the government, nobles oppress ordinary people, right and wrong are turned upside down, and loyal officials are unjustly accused. Commoners at the bottom of society have no voice, while the powerful trample upon their lives and dignity at will. Nie San, a man from the lowest ranks of society, uses human nature, rules, political strategy, and underworld connections to carefully advance his plans step by step. He breaks through the barriers of class, overturns the political establishment, tears his enemies apart, clears his family's name, supports a wise ruler, protects the people, and turns the tide of fate. He wins entirely through intelligence and strategic planning, with no cheats, extraordinary combat abilities, or supernatural powers—only overwhelming intellect, mastery of the rules, and ingenious reversals of identity.
