We all know that detective Conan's 23rd theatrical version of Black Youth Boxing was actually staged in Japan six months ago. This story is actually about a world-famous gem called Blue Fist. But in the19th century, it disappeared in the Sea of Singapore with the shipwreck. Then it was bought by a rich man. We all know that Haidong in Blackfield is collecting a large number of gems, just to find the secrets. If there is no secret in the gem, Haidong of Blackfield will return it. So Kaito Kuroba wants to get this gem at this time.
We all know that Conan drove him to Singapore, and then Haidong Black Market found the information about the gem. And I feel that generally speaking, if Haidong Heiye and Conan appear at the same time, it is usually a cooperative relationship, that is, helping each other out of some difficulties.
So, in fact, apart from the love story between Serena Sebastian and her boyfriend Kyogoku Makoto, the only thing worth seeing is the cooperation between Heiye Haidong and Conan. Another funny thing is that Conan is tanned and turned into a Singaporean child, who looks particularly cute.
