Hehe, I know you're talking about Necromancer Holy Light Cat! This novel was about a necromancer. Because he couldn't cast magic of the undead element, but could cast holy light magic, he was regarded as a saint by the Holy Church, and he was accompanied by a holy light kitten. Furthermore, he had also encountered many dangers, which had exposed many of the internal conspiracies of the Church. I hope you like this fairy's recommendation. Muah ~😗
