In 2090, neuroscientist Ji Linzhou stands on the brink of a breakthrough in digitizing human consciousness, unaware that he has long been on the assassination list of a transnational organization. The National Security Bureau assigns top agent Shen Zhao to pose as a research assistant. This sunny young man’s daily duties involve more than recording data: he also checks the ingredients in the coffee and keeps strange women away from the professor.
When Ji Linzhou discovers that Shen Zhao comes from a family of martial artists, is a cybersecurity expert, and has mastered both neuroscience and computer science by the age of 24, the protection that began with a lie starts to unravel. Only when Shen Zhao faces off alone against three agents from the transnational organization late one night does Ji Linzhou understand: the most dangerous weapon has always stood beside him, wearing the warmest smile.
