Xiao Zhan, former captain of the “Dragon Soul” special forces, infiltrates Binhai City disguised as a delivery worker, carrying the identity of a survivor of genetic experiments and the mystery of his comrades' betrayal. He calculates delivery routes like a sniper lining up a shot, saves an elderly man having a heart attack with battlefield first aid, and converts his electric scooter into a nuclear-powered transforming suit of armor. Amid the bustle of everyday life, he hides the strength of a Zhongnanhai-level bodyguard.

As the four great families' genetic purification plan comes to light, Xiao Zhan uses his identity as a “Delivery Star” to uncover the chemical ingredients used to adulterate top-shelf wine and contacts military agents through Morse code. He gradually reveals the truth: his comrades were turned into bioengineered humans, and he himself is the “genetic savior” cultivated by the Council of the Old Gods! From the top floors of the Dihao Group to the Golden Triangle, home of the genetic source, from an Antarctic refuge to a space research institute, Xiao Zhan undergoes twelve awakenings of his genetic potential, catches an RPG rocket with his bare hands, and takes on the Council of the Old Gods' twelve Knights of the Round Table by himself. He ultimately establishes an international genetic security alliance, only to uncover an even more astonishing genetic truth in the depths of space...
