The story begins with a dead end. A cowardly young man awakens to his ancient heritage in despair and transforms from a mortal into a guardian overnight; from "self-preservation" to "self-preservation" "Guardian" directly enters the protection of the national level, breaks the seal, revives spiritual energy, cultivates the whole people, and makes a civilizational leap. The human race walks out of the earth and fights into the heavens to fight for a chance of survival; the alien army invades, and Blue Star enters the life-and-death battle of civilization to pacify the heavens and restore peace to all living beings. Instead of being the emperor of the heavens, he only becomes a keeper of the scriptures in the world of mortals, returns to his homeland, stays with Su Qing, and lives a life of fishing and farming.
