On a rainy night, silk merchant Ning Wuchen breaks into an abandoned ancient temple to take shelter from the rain, and accidentally discovers wet blood on the ground. As lightning pierced the darkness, he caught a glimpse of a figure hiding behind the Buddha statue. Before he could escape, he was subdued by a mysterious man who was seriously injured. The man's voice was pleasant but angry. Before he died, he thrust a blood-stained secret letter into Ning Wuchen's hands, instructing him to deliver it to "White Plum Swordsman" Ye Hanchuan, and warning that the matter was "related to the survival of the martial arts world." Ning Wuchen discovered that the deceased was actually the famous "Iron Pen Judge" Cui Mingyuan. As soon as he left the ancient temple, he was chased by men in black. At the critical moment, the swordsman in white Ye Hanchuan appears to save him. The secret letter revealed the shocking conspiracy of Duan Tiande, the leader of the martial arts alliance, who colluded with the demon sect to eradicate the leaders of various factions at the gathering of heroes. Ning Wuchen, who was originally forced to get involved, became the target of pursuit because he knew the secret, and had to go with Ye Hanchuan. A businessman who just wants to protect himself and a lonely swordsman embark on a dangerous journey to prevent the catastrophe of martial arts. An encounter at the ancient temple on a rainy night completely changed Ning Wuchen's peaceful life, and pushed him into the center of a whirlpool that could overturn the entire world.
Purpose: Through the involvement of businessmen in Jianghu conspiracies, it shows the awakening and responsibility of ordinary people in the face of righteousness, and interprets the core of the martial arts spirit that "chivalry is not about martial arts, but about the heart".
