The film tells a story about a fool traveling back from modern times to the Chibi era with a box. From *A Chinese Odyssey*, Lau Kar-wai extracted concepts to rework the story; the new film, *Time Traversing Treasure Box*, may once again deploy its "unique kung fu" for a time-travel style narrative. Judging from the current cast list, several main actors from back then, such as Chrissie Choi (Purple Fairy), Cathy Tsai (Iron Fan Princess), and Kong Yu-cheng (Blind Man), have reunited for *Time Traversing Treasure Box*. This clearly shows that director Lau Kar-wai wants to give the audience another taste of *A Chinese Odyssey*. Since the name of this film differs from *A Chinese Odyssey* by only one character, it raises suspicions about their "ambiguous" relationship. However, lead actor Zheng Zhongji denied any resemblance between himself and Zhou Xingchi's previously played character, "Chun Tin Bao". When asked why Lau Kar-wai chose the name *Time Traversing Treasure Box*, he explained that "traversing" means "time travel", and that it is an entirely different story from *Moonlight Treasure Box*. "Traversing means crossing over, and this story is completely different from head to toe compared to *Moonlight Treasure Box*."
Although not officially a sequel to *A Chinese Odyssey*, the story of this film actually originates from two treasures of the Purple Fairy: the Purple-and-Blue Sword and the Moonlight Treasure Box. Chrissie Choi reprises her role as the Purple Fairy, but she is merely a supporting character. The female lead in this film is Sun Li, who plays the Rose Fairy. The Rose Fairy steals the Purple-and-Blue Sword out of admiration for the love between Purple Fairy and Chun Tin Bao, hoping to seek a predestined love. She helps the male protagonist, bandit Qing Yishe (played by Zheng Zhongji), obtain the Moonlight Treasure Box, leading to a wild tale of time travel across different eras. One could say that these two celestial beauties tie together the story of *Time Traversing Treasure Box*. However, under the direction of the mischievous Lau Kar-wai, one becomes a lovesick character while the other turns into a "celestial tragic figure," forming a pair of "neurotic immortals."
