Pet? He levels the whole city

The Story

In the year 3055, alien races treat humanity as mere prey, exploiting flesh and blood for their own amusement. Extinction looms over a species reduced to slaves and toys. Louis Smet, a boy from the slums, changes this fate when he awakens the Ancient God System. Refusing to accept a world built on his people’s suffering, he decides to let it burn. He survives a brutal operating table and climbs the Dragon God Tower in a torrent of blood. He devours gods and demons, absorbing their immense power to fuel his rage. Every humiliation inflicted upon his kind is returned tenfold. With a single roar, he makes the entire universe tremble. The era of human subjugation ends as he reclaims his place.
