Detective Conan: Doctor Cipher [Chinese]

By Gosho Aoyama

In Conan's mystery plots, cracking codes is always one of the most exciting key elements! Did the ancients first invent Braille to encrypt messages? Did the Caesar cipher use letter substitution to hide information? Did the Morse code use dots and dashes to transmit messages? And what about cipher sticks, where a strip of cloth is wrapped around a stick to write on, and when unfolded, it becomes undecipherable ciphertext? Let's explore the history and development of cryptography through these classic codes!
