After Traveling Through Time and Becoming an Evil God, I Can Only Be a Fun Person

Xiang Yan accidentally gained extraordinary power and traveled to a different world. Due to the nature of the power, he had no choice but to become an evil god. Then an evil god appeared who only wanted for his own desires and pleasure, causing trouble for thousands of years. Countless worlds and civilizations have suffered murderous attacks. Many years later, when a reporter asked the great Nightmare Immortal what was his lifelong creed? Xiang Yan replied elegantly, "[Slaanesh], [Khorne], [Tzeentch] and [Nurgle] are my best guides in life." Note: The protagonist does things based on his mood. He may have a sense of morality, but it is not much and flexible. PS: This article has nothing to do with Warhammer. The introduction is too short to move to the main text.
