In the super city "New Chang'an" in 2242, under the neon light and shadow of skyscrapers, ancient rules of the world and cutting-edge technological prosthetics coexist. Ling Kong, an amnesiac prosthetic transformer, was involved in a shocking conspiracy involving major technology giants and underground martial arts sects in order to pursue his broken memories. His only clue is the mysterious prosthetic arm that is out of control and often performs peerless martial arts on its own. During the investigation, he met Mo Yun, an information broker. She used data as a compass to navigate the world of virtuality and reality. From testing each other to joining forces, the two gradually uncovered a huge mystery about consciousness uploading, immortality technology and the secrets of martial arts. They gradually discovered that the "jianghu" of this era was no longer the light of swords and shadows, but the silent fight between codes and electricity.
