The Yin-Yang Master: Dream of Eternity

Centuries ago, a malevolent serpent demon was born from the desires of humans. Four masters—Hongruo, Longye [Jessie Li], Boya [Deng Lun], and Qingming [Mark Chao]—travel to the Imperial City to awaken the four stone guardians and seal the serpent within the body of the empress. Since then, whenever the serpent threatens to emerge, these masters must again journey to the Imperial City to wake the guardians and keep the ancient prison intact. When trouble stirs once more, the quartet—Qingming [Mark Chao], Longye [Jessie Li], Boya [Deng Lun], and the aging Hongruo—return to the heart of the capital to face an unseen peril and protect the realm from a fate that once nearly swallowed it.

Qingming and Boya clash from the start over their divergent views on demons, but they are compelled to work together when a ruthless Hair Demon attacks in the dead of night and kills Hongruo. In the wake of the murder, the empress orders Princess Zhang Ping [Wang Ziwen] to investigate and installs the palace priest He Shouyue [Wang Duo] as Hongruo’s replacement. The new arrangement stirs uneasy echoes: Shouyue bears a striking resemblance to Qingming’s late master, Zhongxing, and as a Spirit Guardian of Zhongxing, he is supposedly here to protect the empress. Yet Shouyue’s presence comes at a perilous cost, for Zhongxing’s death appears to be tied to his own.

A failed assassination attempt on the empress fans distrust among the four masters, and suspicion flares as each man follows his own path. Longye is accused almost as soon as she uncovers something vital, but before she can reveal it, the Hair Demon strikes again and she falls. With her dying breath, she tries to pass along her discovery to Qingming, but the message is misread as an accusation against the princess. Boya refuses to accept that the princess could be the culprit, insisting instead that He Shouyue must be the traitor. The two men split to confront the princess and Shouyue separately, while the princess confronts Shouyue with anger—accusing him of Hongruo’s and Longye’s deaths. Shouyue, cool and calculating, argues that their sacrifices were necessary to protect their secrets, and that in order to silence others who know too much, both Boya and Qingming must also die.

When Qingming finally faces the princess, she is seized by the Hair Demon. He hunts the demon down and discovers that it has waited sixty years to avenge the princess for her own death. The truth dawns on him: the princess has not aged at all for sixty years, which leads him to suspect that she is the true empress and the hidden vessel of the serpent. The duo—Qingming and Boya—launch a direct confrontation with the princess and Shouyue to uncover the real plan: to save Shouyue from dying, he must become the serpent’s new vessel, granting immortality to the serpent itself. The princess, realizing she can no longer remain immortal, bears the serpent into the world and recalls her first meeting with Zhongxing: a forbidden love that had once drawn Zhongxing away and driven him to create He Shouyue as a protection for her. Zhongxing’s memory haunts the moment, and the princess confesses that he once loved her before he left.

The princess and Shouyue flee—riding a now-giant serpent—while Boya and Qingming give chase. The princess, realizing the folly of their plan, attempts to commit suicide with Shouyue, but they are swallowed by the monstrous coil. Boya notes that only three of the four stone guardians have awakened; Shouyue has not stirred the guardian meant for him, which would allow the serpent to depart the Imperial City. From the serpent’s ashes, Shouyue emerges as the new vessel and engages Boya, Qingming, and the Spirit Guardians that Qingming summons—the Snow Hound, the Killing Stone, and the Mad Painter—in a desperate clash for control. Boya, meanwhile, awakens as a Spirit Guardian himself, manifesting as the Crimson Bird.

As the Crimson Bird and Shouyue battle, Qingming makes a pivotal move: he slips inside the serpent to show the princess the last memory he shared with Zhongxing. Zhongxing reveals his enduring love for the princess and urges her to do the right thing. Qingming and the princess escape the serpent momentarily, and the princess—no longer immortal since she has shed the serpent’s vessel—kills herself with the sacred sword Zhongxing had named Fangyue. In the chaos, Shouyue is impaled by the Crimson Bird, and the serpent begins to falter. The Crimson Bird sacrifices himself to save Qingming, allowing Shouyue to rise again from the serpent’s ashes but at a terrible cost: Qingming dives in front of a fatal strike intended for Boya and, in a moment of clarity, grasps the real meaning of being a Yin-Yang Master.

Boya awakens to the new reality of their bond and fate, and the two friends share a quiet goodbye as the entombed Longye somehow remains alive. The city breathes again, but the cost is high, and the line between guardian and host, vessel and freedom, has blurred forever.
