Reincarnation Of The Strongest Death Knight

He was a Death Knight that served as the strongest thrall of the Death God, and the most loyal servant who followed the Death God to the very latter. Until one day he drove a sword through the back of the Death God and killed him. He went on a rampage and no man, no god could stop him… He destroyed the world. And perished with it. Yet he had no name and sense of self. However, as the Thrones of the Heavens would have it, he rencarnated. But this time in a different world with a sense of self, a name and the memories of his past life. What would the Death Knight who destroyed the world without a sense of self do to this new world, now that he has a name. Would he be its salvation or its ruin, especially when he might have a little bit of a tendency for evil things. — Description from novelcodex.org
