The film opens with a flashback to the events of the first movie, where Jacky Cheung as Yin seals away the tree demon and tells the scholar Ning Tsai Shen that it will awaken again after a hundred years. The forward gaze of that ancient warning sets the stage for a collision between old powers and new lives, as the past refuses to stay buried.
One hundred years later, two Buddhist monks—master Bai Yun and his somewhat clumsy disciple Shi Fang—are tasked with transporting a golden Buddha statue. On their journey, they encounter the relatively honorable mercenary Yin, a Taoist swordsman whose name echoes the original Yin and who even faced rejection from his legendary predecessor when he sought to become a student. During a conversation with a merchant, Yin accidentally cuts the roof off Shi Fang’s backpack, exposing the gleaming Buddha statue inside. The moment exposes not only treasure but the fragile balance between duty and temptation that threads through the entire story.
As they travel, the party is beset by thieves and rowdy locals, forcing them to seek shelter at a temple that is none other than the Orchid Temple—the same sanctum seen in the first film. Unbeknownst to the travelers, they are shadowed by bandits who, upon entering the temple precincts, encounter an otherworldly danger. One bandit trips over a corpse arm and mistakes it for a ghost, prompting the frightened group to flee because the place is rumored to be haunted. The lurking tree demon then rises from the shadows, seizes the remaining bandits, and vanishes them, leaving silence and a chilling echo in the air.
While the monks are meditating, Master Bai Yun investigates the disturbance, instructing Shi Fang to remain within the temple walls. The tree demon, aware of these intruders, summons a female ghost, Lotus, to lure Shi Fang away. Lotus, Joey Wong Cho-Yin in the role, makes bold attempts to seduce the young monk, testing his resolve. When Shi Fang discovers she is a ghost, Lotus makes a move to kill him on orders from the demon, but he repels her with mantras and, moved by compassion, allows her to depart when his master returns. Yet over the following nights, Lotus returns, and an unlikely bond grows between them.
Meanwhile, a second spirit, Butterfly, Nina Li Chi, grows suspicious of Lotus. The two ghosts are rivals for the Tree Demon’s favor, and Butterfly schemes to seize Shi Fang and reveal Lotus’s deception. When the Tree Demon attempts to capture the monk, Bai Yun intervenes, using his staff to transport his student to safety, only to have himself seized in the ensuing struggle.
Moved to act, Shi Fang seeks help from Yin to rescue his master and to recover Lotus’s urn. The two warriors join forces, facing the Tree Demon with a blend of Taoist and Buddhist techniques. Their combined power eventually shatters the demon’s grip, saving Shi Fang and, to some extent, Lotus as well. Yet the reunion is bittersweet—though Bai Yun disapproves of Shi Fang’s romance with a ghost, he does not abandon Lotus, and ultimately helps ensure her safety.
With the Tree Demon defeated, a new threat—the Black Mountain Demon—dramatically intensifies the pursuit. He raises high pillars to block any escape and darkens the sky, creating a suffocating barrier of shadow that clings to the earth. In response, Master Bai Yun casts a potent spell, sacrificing a portion of his own life energy by dripping his blood onto Shi Fang, which has taken on a golden hue from accumulated spiritual energy. Lotus then carries Shi Fang up into the sky, above the oppressive clouds, enabling him to channel the Buddha’s power and pierce the demon’s barrier of darkness so that sunlight can finally return to the world.
In the climactic moment, the sunlight breaks the gloom and the Black Mountain Demon is undone by the very light it sought to blot out. As the dawn returns, Shi Fang fears for Lotus’s safety, believing she may have perished in the glare. He searches and eventually finds her sheltered beneath a pile of rocks, safe from the sun’s rays. Lotus reveals that her spirit will accompany him as long as he carries her urn away from the temple, a final vow that forever binds their fates to the fragile, luminous line between life and the supernatural.
