On a rainy night in the south of the Yangtze River, Wudang successor Su Qinghan, who carries the secret of the "Xuantie Sword Manual", encounters the famous "Seven-Star Scimitar" Ling Shuang - the two people who were supposed to be the pursuer and the fugitive, unexpectedly stood on the same front because of a sudden siege by the Qingcheng Sect.
The sword manual hides the truth about the catastrophe in the martial arts world twenty years ago: the bloody storm that severely damaged Wudang and Emei was actually a conspiracy secretly controlled by the imperial court. In order to reveal the truth, Su Qinghan took the broken jade sword to search for evidence in the world, while Ling Shuang gave up the killer's reward and protected him with a machete. From the first trace of the shadow guard revealed in the secret of the ruined temple, to the dangerous rescue of Master Jingxuan at Qixia Mountain, to the gathering of martial arts heroes at Wudang Mountain, the two of them broke through the obstacles all the way. The lightness and agility of the sword intertwined with the fierceness of the knife, becoming the most powerful blade against the tyranny of the imperial court.
When the Jin Yiwei marched towards Wudang, and when the imperial army encircled and suppressed the Yangzhou uprising army, the two powers joined forces to break the situation: Su Qinghan used his unique sword skills to tear open the enemy's defense line, Ling Shuang used the seven-star scimitar to kill the mastermind behind the scenes, and even instigated the upright general Li Qing to gather the resistance forces of the rivers, lakes and courts, and finally went straight to the capital to end the tyranny.
This is a journey that begins with pursuit and ends side by side. The green front mirrors the frost blade, and the two strong hands hold hands. With chivalry as the front and trust as the blade, in the conspiracy and war, the catastrophe is solved and the peace of the world and the world is restored.
