Witcher Hunt: from Ultramarine to Emperor

In a world where wizards are king, wizards use mortals as livestock, breeding, enslaving, experimenting, and killing them. Lister was reborn from the test subjects abandoned by the wizard, carrying the Analytical Eye and the Ember Workshop, and used science as a weapon to hunt down these villains called wizards. Psychic? Spell? They are all causes of the destruction of the world! I will start by becoming an Ultramarine and eliminate these traitors who have abandoned the human bloodline and switched to the monster bloodline! Until I achieve the title of Emperor as a pure-blood human!
