Chen Liao, a top identity broker in the northern black market, has the special ability to copy other people's identities and memories. However, due to a well-planned frame-up, he was forced to be involved in the warlord's civil strife and the conspiracy of the mysterious organization "Identity Bureau". He originally wanted to make enough money to retire, but unexpectedly discovered the mystery of his life experience that he was the young leader of the Shou Ling tribe and was once an experimental subject. In order to clear his grievances and find the truth about his parents, Chen Liao formed an alliance with the marshal guard Zhao Hu, the female killer Su Mei and others to fight against the Identity Bureau's cruel experiments and power ambitions. As the investigation deepens, they discover that behind the Identity Bureau lies a mysterious force that controls the world. It also involves interstellar threats such as the "Source of Identity" that can give life identity, the "Void Tribe" that feeds on identity memories, and the "Reverse Alliance" that subverts the balance of the universe. From the swords and shadows in the Northern City, to the seal protection in the Mobei wilderness, to the secret exploration in the American rainforest and the ultimate showdown in the depths of the universe, Chen Liao always sticks to his heart and unites the global forces of justice. In the game of identity, power and survival, he grows from a lone avenger to a core guardian who protects the earth and balances the energy of the universe. This war about the essence of identity and the survival of the universe is far from over.
