In the super city "New Kowloon City" in 2242, under the neon light and shadow of the skyscrapers, there is an unknown "jianghu" hidden. The knights here no longer just rely on breathing and breathing to practice qi. They use neural interfaces to download martial arts, use nanomaterials to recast their muscles and bones, and use high-energy batteries to drive their internal forces. Ancient sects and technology giants infiltrate each other, competing for the final explanation of a mysterious power called "Qi".
Long Jin is the only descendant of the "Yunxin Sect" - the last ancient sect that insists on pure physical cultivation. When the sect's supreme mental method "Dragon Heart Art" was stolen, he had to step into this familiar yet unfamiliar steel jungle to find the inherited fire.
Night Falcon is Sky Technology's top prosthetic executive, a perfect weapon that has lost its past and is only born for the mission. Her next goal is to seize the "Dragon Heart Secret" and eliminate all insiders, including Long Jin.
When the purest descendant of ancient martial arts meets the most advanced technological creation, a duel about Tao and law, flesh and steel, memory and future is inevitable. However, every time they had a confrontation, scenes that were not his own flashed through Night Falcon's broken memories, and Long Jin also discovered that behind the stolen mind book, there seemed to be a shocking secret that could subvert the entire order of New Kowloon City. Are they old enemies, or puppets manipulated by the same thread of fate?
