Undead Scourge: How Did I Start Helping the Undead?

The Scourge of the Undead destroyed everything, leaving Brian Wilder with only hatred. And the demon awakening in his body needs this hatred as nourishment. The devil said: "I will not give you power, that is too boring. I will give you 'methods' - how to find companions, how to win, how to approach your enemy step by step." But every method is a carefully packaged poison: Because what the devil wants is never his success, but the pain, anger and sadness that are constantly brewing in his pursuit of success. But gradually, when Brian no longer indulged in his revenge, he realized something was wrong. Then until Brian looked up at the looming cracks outside the sky, he heard the screams of the falling remains of the gods. Deep in his soul, the devil let out a contented, almost gentle sigh: "Finally... Touched the edge of the truth." (This is not a cool novel. Everyone close to the male protagonist may be sacrificed at any time.)
