Detective Dee: the Dragon Storm

Era background: In the first year of Tang Shenlong (705), Wu Zetian abdicated and Zhongzong Li Xian was restored. The situation in the DPRK is turbulent, and there are undercurrents from all parties. [Main line settings] The core mystery: Bizarre murders occurred one after another in Luoyang City. The deceased were all close associates of the heroes who participated in the "Dragon Coup". A bronze dragon scale was left next to the corpse, with the word "tail" engraved on the back of the dragon scale. Di Renjie noticed that someone was liquidating the participants in the coup, and behind this was a larger conspiracy that had not yet been completed: someone wanted to completely cut off the tail of the "Dragon", or even... Behead it. Hidden line: A mysterious organization that calls itself "The Wagtail Man" has members all over the government and the public. Their ultimate goal is not revenge, but to support a "true dragon".
