The Undead Monarch Began to Practice Holy Light Magic

Three hundred years, a whole three hundred years, do you know how I got here these three hundred years? Why can an elf monarch hug a long-legged elf girl while eating, drinking and having fun? Why does the demon king have a bunch of succubi rubbing his shoulders and beating his legs? Why is there always a female orc beside the Lord of Beasts... Well, forget it, And I, the Undead Lord, am trapped in this pile of bones, My soul is a strong man! I want flesh and blood too, no one can stop me, Kingdoms, churches, magician associations... I will destroy anyone who stands in their way!
