When a tyrant, conqueror of the world, is killed by a god and ordered to become his apostle, would he accept such an offer? Of course he does. Why does he do so? Let me ask you a question to answer the question. What's the point of living when you already have everything? None. With one task, a peculiar man is sent upon a world where heroes and villains with technology, powers, armies of monsters or other crazy things rule. What is said task? Well, bring chaos to that world. It's as easy as that~.
