The Duel of the Century

Ximen postponed the duel because the entire confrontation was part of Wang An's conspiracy. The eunuch needed time to set up his assassination plot against the emperor. By delaying the fight, Wang An could use the fake Ye in the actual duel while the real Ye carried out the assassination. The postponement also allowed rumors to spread about Ximen being afraid, which served the conspirators' needs.

Earlier, Lu Xiaofeng notices the unusual delay fuels speculation among martial artists, hinting at hidden motives beyond the duel itself.

Ye was poisoned by agents working for Wang An, the chief imperial eunuch. The poisoning served a dual purpose: it made Ye physically weakened and therefore more controllable, and it created the story that Ximen could only cure Ye with an antidote. This gave Wang An leverage over Ye and a way to manipulate him into the assassination plot.

Leng Qingqiu's desperate search for an antidote and Ximen's willingness to provide one establish early that Ye's poisoning was engineered for control.

Wang An orchestrated a scheme to assassinate the current emperor and install a fake heir (the bastard of the previous emperor) on the throne. The plan involved merging China with Tibet through a marriage to a Tibetan princess from the Holy Water Sect. The publicized duel between Ximen and Ye was a distraction to draw imperial guards away from the emperor, allowing the real Ye to carry out the assassination.

The presence of the White Cloud sect leader Kuo Chingfeng, who is Wang An's godchild, and the arrival of the Holy Water Sect's chief lama early in the investigation hints at the political conspiracy.

Wang An created a fake Ye Gucheng to serve as a decoy in the public duel while the real Ye carried out the assassination. The impostor would fight Ximen Chuixue in what everyone believed was the real confrontation, drawing attention and protection away from the emperor's quarters where the real Ye would strike. This double scheme allowed the conspiracy to proceed while keeping the true assassination hidden.

The reveal of an imposter sent to kill Lu at Ye's summons, combined with the mysterious wax figures, plant seeds of identity confusion.

No, Ye Gucheng did not kill Zhang Renying. When Lu Xiaofeng and Ximen examine Zhang's body at the crematorium, Ximen concludes the murder was not Ye's doing. The wax figures Yan Renying found on Zhang's body pointed to the true killers: Wang An's agents and the Holy Water Sect lamas. The framing was designed to create bad blood between Ye and Ximen, setting up the politically motivated duel.

Yan Renying's accusation at the brothel, which Ye firmly denies, early establishes doubt about his guilt.

Ye Gucheng was manipulated into believing his mission would bring prosperity to his country. He was kept ignorant of the broader conspiracy and thought he was serving a noble cause. Wang An exploited Ye's sense of patriotism and his desperation to save his dying wife, using the promised antidote for Leng Qingqiu as additional leverage.

Ye himself tells Lu he does not fully understand why he agreed to the duel, suggesting his motivations are being externally influenced.

Ye chose to die by Ximen's sword rather than be captured or live in defeat. Though he was manipulated by Wang An, Ye had still agreed to assassinate the emperor, an act of treason. Rather than surrender to the shame of his manipulation, Ye chose an honorable death in combat. His final request was for Ximen to kill him, and Lu eulogized him as a tragic figure who spent his life seeking a greater truth.

Throughout the film, Ye is portrayed as an honorable swordsman manipulated by forces beyond his understanding, setting up his tragic end.

Lu Xiaofeng served as the investigator who pieced together the truth behind the duel. He assembled a team, consulted Guisun Daye, tracked down gamblers who knew about the bet, discovered the poison, found the wax figures, and ultimately raced to the emperor's chambers to prevent the assassination. Lu's involvement was what exposed Wang An's plot and saved the emperor's life.

Lu's decision to form a team and pursue hidden motives establishes him as the driving force unraveling the mystery from the beginning.

The fake Ye fought Ximen Chuixue in the staged duel while the real assassination attempt occurred. During the climactic confrontation at the emperor's quarters, the fake Ye was present alongside Wang An and Kuo Chingfeng. When Ye turned against his manipulators, the fake Ye was defeated along with the other conspirators. The impostor was part of Wang An's forces and faced capture or death along with the eunuch and the false heir.

The reveal of an imposter Ye at Lu's summons early demonstrates Wang An's willingness to use identity deception.

The highly publicized duel drew martial artists, imperial guards, and public attention away from the emperor. While everyone focused on the dramatic showdown between two legendary swordsmen, the real Ye slipped into the emperor's quarters to carry out the assassination. The fight was staged to empty the palace of protection, making it easier for Wang An's coup to succeed.

The intense media attention and rumors around the postponed duel establish it as the most talked-about event in the martial world, making it the perfect cover.

Kuo Chingfeng was the leader of the White Cloud sect and the godchild of Wang An. He managed the gambling operation involving the bet on the duel and served as a key figure in the conspiracy. After Li Yanbei relinquished his bet to Kuo, the White Cloud sect became fully entangled in Wang An's political scheme. Kuo attempted to kill Ye at the climactic confrontation but was defeated.

Li's transfer of the bet to Kuo signals the White Cloud sect's direct involvement in the conspiracy.

Yan Renying believed Ye had murdered his senior master, Zhang Renying. At the brothel confrontation, Yan accused Ye of the killing and attempted revenge. However, Ye denied the charge, and Yan was unable to pursue effectively because his horse, carrying Zhang's body, escaped. This attack established early in the story that Ye was suspected of the murder, though the truth would later reveal he was framed.

The brothel confrontation introduces the murder mystery and sets the revenge plot in motion.
