The Magpie Bridge mentioned in the ancient version of the Yijin Jing was a term from an ancient martial arts novel. It referred to a special martial art that used a special technique to make one's body's strength and speed reach the extreme, allowing one to move as fast as the Magpie Bridge to achieve the purpose of attack and defense. This kind of martial art was very famous in martial arts novels and was called the Magpie Bridge Technique or the Fast Magpie Bridge Technique. However, it should be noted that the specific cultivation methods and techniques of this martial art were not described in detail in the original work. Therefore, the specific implementation and application of this technique still needed to be understood according to the plot of the novel and the imagination of the readers.
