Warhammer 40,000: The End of Annihilation

The protagonist, Ling Ji, was a lowly slave in a primitive civilization in his previous life. In that cruel world of cannibalism, he witnessed his fellow citizens being treated as food by the powerful and playthings by alien forces. He suppressed his humble longing for warmth and, with his extreme cunning and ruthless methods, meticulously planned and destroyed half of the primitive civilization's world—a "liberation" he offered to his suffering compatriots, and the grandest art in his eyes. His only regret was failing to drag the other half of the world into annihilation. A gift (or malice) from an unknown entity led him to be reborn in the 41st millennium of the Holy Empire of Humanity, reduced to a serf in the Nest Capital. The decay, brutality, and cannibalistic nature of this world are exactly the same as in his previous life. What will Ling Ji choose to do now?
