Awakening in the body of an innocent child, the fallen king finds himself in a parallel world, where he discovers his true lineage as "Cosmos," the illegitimate son of an emperor and a maid. As he grows into adulthood, Cosmos faces a treacherous conspiracy that brings about his disgrace and banishment. Framed by his conniving stepmother and siblings for a crime he did not commit, Cosmos is stripped of his rightful birthright and bestowed with the modest title of a mere baron. To compound his isolation, his own father commands him to govern a lawless city steeped in criminality, corruption, and anarchy. In a bid to aid him in this seemingly insurmountable task, his father grants him a contingent of 500 soldiers. Armed with the memories of his past as a great king and fueled by the revelation of his true identity, Cosmos embraces his destiny with unwavering determination. Resolute in his mission to restore justice and reclaim his rightful place, he embarks on a transformative journey. Drawing upon his strategic acumen, cultivation prowess, and innate leadership abilities, Cosmos endeavors to reform the chaotic city and rally a loyal following.
