On a rainy night, Jiang Liu, a delivery boy, was working hard to earn tuition, but unexpectedly awakened the "Heavenly Road System" - the blue path line emerging in his eyes, which could calculate the optimal solution for all things. With this ability, he climbed up to a 42-story building in 3 minutes, overturned a transnational kidnapper with a takeaway order, and his peaceful life was completely overturned.
The next day, three black cars drove into the site and were approached by the state paranormal department. Only then did he realize that the female CEO he rescued was actually the leader of the special agent team, and that his seemingly ordinary mother was actually the first-generation ability user who mysteriously disappeared twenty years ago. An old photo of a non-existent military uniform and a physical examination report with a brain activity level of 3000% dragged him into unfathomable undercurrents: the kidnapping of the transnational criminal organization "Northern Desert", the periodic "sample harvest" of higher civilizations, and even the cruel truth that the entire planet has become an experimental site.
Jiang Liu, who was forced to recruit, had to deal with the game of multiple forces. His biological father was actually the leader of the enemy, his mentor might have hidden agendas, and the woman who moved his heart was actually an indifferent observer from a higher civilization. With the power of a path that can evolve to control cause and effect, Jiang Liu's every choice is a matter of life and death. Should he become a chess piece at the mercy of others and inherit the so-called "family business", or should he use his mortal body to figure out an unprecedented path of resistance for the people he loves and the world beneath his feet?
From urban street fighting to gunfire in the rainforest, from data torrent to reverse causality, this is an extreme counterattack by a deliveryman in a desperate situation, for freedom and true love, against the established destiny. The path points to a journey.
