Why does Jide Li, the magician of Conan Blade, pretend to be Shinichi?

At the beginning of the eighth edition of "The Blade Magician", Kidd openly pretends to be Kudou Shinichi in order to see the terrain (in front of Conan in order to sneak shots) ... that's obvious provocation). Kidd already knew Conan's identity. Kidd knew Conan's identity was in the theatrical version 3 "The Magician at the End of the Century". There he disguised himself as a policeman in Bai Niao, and through the monitoring and observation of Conan, he deduced his identity. In that episode, Conan signed a lottery ticket and said, "Travel, your identity will be exposed, don't go." At first we all thought it meant Xiaolan. Xiaolan had doubts about Conan, but she didn't know the truth in the end. In fact, the person mentioned in the sign refers to Kidd, who knew about it in that episode, so in the end Kidd pretended to be Conan's new group to hide from Xiaolan in order to repay Conan for saving his pigeon.
