Wang Han Investigates Case Involving Star Mirror

Wang Han is investigating the disappearance of a 'Star Mirror' which may have been taken to Luoyang. A group of accomplices attacked Yihongyuan to obtain the diagram from Ajin, which also explains the incident involving 'Tongmen Xiaoniang'. These individuals rescued Su Zhen from Puzhou government and arranged for her to be in Luoyang as a 'Chang Nü' to lure Wei Yuejiang out. Wang Han's cousin, Zi Huan, was sent to apologize to Lai Junchen on Wang Han's behalf. Wang Han and four friends are drawn into a murder case amidst political chaos during Empress Wu Zetian's reign. Wei Yuejiang's actions, including returning to Hongyuan and Hongguan, were motivated by the 'Xuanji Tu'. Prince Jinyang Wang Han was summoned to the palace by an imperial envoy under Princess Taiping's orders. The text also mentions the rebuilding and renaming of 'Zhetianmen' to 'Yingtianmen' during a period when a ruler changed the dynasty name to Zhou and called himself 'Zhetian Huangdi'. Wang Han's home was surrounded by officials under Luo Yang County Magistrate's orders, with intent to arrest everyone. Wei Yuejiang's actions suggest he is seeking the 'Xuanji Tu' (mysterious map), which Wang Han also believes is the motive for a group that killed Hu Bing and sold his wife into prostitution, and later rescued Su Zhen to lure Wei Yuejiang. Wang Han questioned why he was being pursued after attending a banquet at Lai Junchen's home, learning that Lai Junchen acted preemptively due to Wang Han's refusal to abandon Yu Xian. Wei Yuejiang is seeking the 'Xuanji Tu' and has been to the 'Yi Hong Yuan' (One Red Courtyard) for it.
