Mingdynasty 中,百姓受难于东厂势力,正直而勇敢的锦衣卫赵正武,与朱大典、张震,被帝王赐名为《三剑侠》。由于目睹民间之苦难,赵正心生愿为人民请命。偶然遇见叶向高之女儿叶敏,双方暗情绽放。 sudden, the emperor dies under mysterious circumstances, and the crown prince, aided by Lei Xing, successfully ascends to the throne.
However, the deceased emperor's secret is far from over... To avoid debts and gambling addiction, Wei Jin Zhong manipulates the east factory forces and corrupt officials across various regions, resulting in increased taxes and suffering among the people. A fabric worker named Tang Lang refuses to submit and organizes a tax protest march. The investigation of this matter catches the attention of none other than Beizhuang himself.
Tang Lang crosses paths with Zhang Jing and Shaolin masters, mistaking them for guardsmen. When Beizhong arrives in time to resolve the confusion, he develops a deep respect for Tang Lang. The three meet again three times, during which Tang Lang sacrifices herself to save Beizhong, leaving him with a feeling of gratitude that goes beyond conscious thought.
Motivated by national interest and guided by righteousness, Beizhong decides to distance himself from Lei Sheng, inadvertently creating the tragic sword style known as "Sorrowful Sword Technique." The battle begins, with Beizhong intentionally revealing a weak spot. The emperor uses his mastery of the Heavenly Anger Sword to wound Beizhong, but the latter is unexpectedly poisoned by the emperor instead.
The emperor emerges victorious and Lei Sheng officially enters the palace. The emperor, inspired by his new bride, becomes a more proactive ruler, eventually becoming a respected monarch. However, Lei Sheng's ambition for power resurfaces once again...

The emperor believes Lei Sheng's slander and orders Beizhong's arrest. In a surprising turn of events, thousands of guardsmen storm the Forbidden City, rescuing the emperor and Lei Ming while killing Zhang Jing in the process.
Beizhong and Tang Lang arrive just in time to confront Lei Sheng, but it is too late for Zhang Jing, who has already succumbed to his injuries. With the heavens crying down and thunderstorms brewing, a bloody and fierce battle erupts...
