Under the city shrouded in cyberneon, there are mysterious codes left over from a century-old history. Explorer Lu Chen accidentally activated the "tracing back" golden finger, which was able to decipher the secrets deep in the city. However, it also attracted dark opponents who coveted power, peers who were jealous of his talent, and even alien forces lurking on the earth. When he was tracing the historical truth, he met Su Nian, who had a tragic life experience but was tenacious, and the two worked together to fight against various crises. When conventional methods fail, Lu Chen uses counter-routine operations to break the deadlock repeatedly. From neon alleys to virtual battlefields, he wants to uncover the secrets left over from history, but also to protect the people around him and carve out a path of survival for an explorer in the cyber city.
