Detective Conan Kyogoku Makoto is a suspect. What does the last message Liang Shi received mean?

Original: ps: Have you seen the Magic Messenger?

Have you ever seen a magician's reasoning ability? Personally, I understand that the magician refers to Conan who turned Richard Moore into a detective. It means that the sender already knows Conan's identity.

Introduction: Detective Conan is an animated work of the same name based on the detective cartoon Detective Conan created by Japanese cartoonist G?sh? Aoyama. A cartoon with detective reasoning as the theme tells the story that Kudou Shinichi, a senior high school detective, was poisoned by a mysterious black organization code-named APTX4869, and his body was reduced to a pupil, so he concealed his identity and cracked various cases while investigating the organization. Originally created in 1994, it is still serialized in Japanese elementary school comic magazine "Weekly Youth Sunday". The animation was produced by V 1 Studio, broadcast on June 8, 1996 by1Japan Yomiuri TV Station, and it is still broadcast today.

Personal data:

1) Kyogoku Makoto: The character in the Japanese anime Detective Conan. All-Japan karate champion, titled "Beat your son". I began to like this garden after seeing Serena Sebastian's posture of desperately cheering for his friend Mao Lilan in a karate competition. After that, they rescued the garden many times and became lovers. Now I am studying abroad.

2) Shi Liang: The character in the Japanese anime Detective Conan. A female high school student who claims to be a detective, and the sister of Akai Shuuichi, a search officer of the Federal Bureau of Investigation. He transferred to Danish High School Class B for two years and became a classmate of Mao Lilan and Serena Sebastian. Good at Jeet Kune Do and excellent in reasoning. Always wear neutral clothes, flat chest. I am interested in the identities of Conan and Haiyuan Ai in Edogawa. I seem to know Conan's true identity and meet Xinyi and Xiaolan somewhere. The rest of the identity is unknown.
