Espionage

Information transmission is not limited to radio waves, but there is also a kind of "brain teaser". In order to obtain the top-secret fortress map of the Japanese army, the lurker Guo Fei had to be awakened. The transmission of information relies on word splitting, homophones, and code words in paintings - for example, a picture of "turtle shell stuck in the railing" can convey the message "the big cover can't come out". His opponent is the spy Midnight Wolf Shadow, a being with high IQ. This novel is purely fictional, but the cruelty of the game is far more real than reality.
