An illegitimate son of an imperial prince and a papal saint, lived for twenty years without knowing his identity, and became a black laborer in the Federation. Soon after, he even transformed into a criminal who illegally sells magic crystals, a desperado who licks blood every day, and a bastard who lives in a haze. But such a bastard gradually became the notorious mage thug leader in the Federation, and also became a hero of the Federation by accident.
However, just when (Jack Byrne) was getting carried away, his father (Bourne George) ascended the throne of the empire and proclaimed himself emperor, and his identity was also revealed by Bourne George. From then on, Jack Byrne became a spy that everyone in the Federation wanted to beat, thus creating a galaxy butcher who was feared by the entire universe!
