Plot

The story is set in the final years of Emperor Gaozong's reign. The emperor and Wu Zetian overrule opposition and send a fleet against an enemy state, but the fleet is struck by a mysterious force at sea and nearly annihilated. Popular rumor blames the disaster on the Dragon King (龙王), a sea god the fleet is said to have offended. In Luoyang, the famed courtesan Yin Ruiji is targeted for abduction, and the young Di Renjie, newly arrived to report for duty at the Dali Temple, becomes entangled in the case.³^•⁸

Di Renjie rescues Ruiji and wins the trust of the temple's chief, Yuchi Zhenjin, and together with the skilled physician Shatuozhong the three investigate the "Dragon King case." Ruiji's former lover Yuan Zhen, a wealthy young man who vanished without explanation, turns out to be key to the mystery, which connects the disappearances at sea to a conspiracy threatening the Tang royal house.³ The film's antagonists include a masked figure called the Mystic Man, a giant sea monster identified in promotion as the Ao Huang (鳌皇), described as Asia's largest movie monster, and a plot involving poison insects (蛊虫).²

Production

Tsui Hark conceived the film while writing Detective Dee and the Mystery of the Phantom Flame: side stories kept emerging during that screenplay, and after shooting he discussed with Chen Kuo-fu and the screenwriter Chang Chia-lu whether to film the episode of Dee's first arrival at the Dali Temple as its own movie. Producer Wang Zhonglei admitted initial hesitation about entrusting a large-scale production to a young cast, but the success of the first film gave the project confidence.⁹

Underwater 3D. The production was promoted as the first Chinese-language film to enter underwater 3D, with full native 3D shooting described as being at the top Asian technical level. Tsui Hark said the underwater setting served the story in two ways: it forced Dee to overcome his weakness in the water during the investigation, and water's mysterious qualities allowed strange cases to arise and relationships among characters to shift, including the bonding of the three leads.²^•⁹ Production costs reached 150 million yuan, with marketing bringing the total to about 200 million yuan; Wang Zhonglei said the largest share went to post-production visual effects, and the film used more than 60 sets, a record for a Tsui Hark production.⁴^•⁹

An eight-minute 3D reel screened for international distributors at the Cannes Film Festival sold rights to buyers from 32 countries and regions, and the film was subsequently released in more than 50 countries and territories.¹⁰^•⁴

Reception and box office

The film opened on 28 September 2013 and dominated the National Day holiday box office. Reported opening-day figures differ among sources: 54.30 million yuan,¹¹ 56.0 million yuan,¹² or 64.0 million yuan.¹³ Cumulative totals are consistent across reports: over 100 million yuan in three days, over 400 million in nine days, and over 300 million yuan during the 30 September to 6 October holiday week alone, contributing more than half of that holiday's roughly 600 million yuan total.¹¹^•¹²^•¹⁴

By 14 October, sixteen days after release, the film had taken 544 million yuan, breaking Tsui Hark's own record of 540.55 million yuan set by Flying Swords of Dragon Gate and far exceeding the near-300 million yuan of Detective Dee and the Mystery of the Phantom Flame.⁵ It went on to pass 600 million yuan, becoming the eighth domestic film in the mainland market to cross that threshold and finishing 2013 as the third-highest-grossing film in China behind Journey to the West: Conquering the Demons and Iron Man 3.¹⁵^•⁶ Outside mainland China, the film earned about 99.4 million US dollars worldwide on The Numbers' accounting, of which only about 88,000 dollars came from the limited North American release.¹⁶

Critical response. Reviews praised the spectacle and divided over the story. A Southern Metropolis Daily-organized preview screening in Guangzhou found audiences nearly unanimous that the 3D effects, including the naval battle, an underwater kiss, a cliff-top duel, the monster smashing warships, and an underwater horse-riding sequence, were striking and spectacular.¹⁷ Sina's review compared the film's relentless pacing to Sherlock Holmes, Pirates of the Caribbean, and Indiana Jones, calling it successful on those terms while noting that revealing the mastermind too early weakened the second half's suspense compared with the first film.⁸ A Douban review titled "good technique, watery plot" made the same trade-off from the opposite direction, arguing that the mystery's clues were contrived to flatter the detective.¹⁸ A commentary in Overseas Network observed that across Tsui Hark's recent work, from Flying Swords of Dragon Gate through the Detective Dee films, the fantasy element had grown stronger while the wuxia element faded and the fight scenes became increasingly technology-driven.¹⁹

Place in the series

The film is the second entry in Tsui Hark's Detective Dee trilogy, between Detective Dee and the Mystery of the Phantom Flame (2010) and Detective Dee: The Four Heavenly Kings (2018), and it moves the timeline back to Dee's youth, before Wu Zetian's personal rule.⁷^•⁴ At the Beijing premiere Tsui Hark said he hoped to make Dee a representative hero of justice for Chinese audiences, in the manner of a Chinese answer to the James Bond series, and suggested that more than twenty sequels were possible.²⁰ The film's end credits carry 23 concept images, which Tsui Hark said represented 23 planned Dee mystery cases, including titles such as Lover's Vine, The Gorean Beauty, Valley of the Netherworld God, and Heavenly Fire; he said audience preferences would help decide which stories became sequels.²¹ The next film, The Four Heavenly Kings, picks up after the Dragon King case, with Dee caught in a vortex of power and intrigue.⁷
