Reincarnated in Another World, Becoming a Beautiful Nun

As a church nun, but an undercover agent planted by a heretical organization, Olivia felt she could be burned at the stake at any moment. Fortunately, she had the advantage of time travel: a magic mirror that could answer all her questions. From the monastery to the church, from the church to the capital, and from the capital to the whole world, the gradually repaired magic mirror revealed more and more secrets to Olivia. She knew about the advancement rituals for various extraordinary paths. She knew the methods of sealing many forbidden items. She knows the best meditation methods. She knows what everyone likes, dislikes, and needs. She is not a god, yet she seems like one, watching over the world. The battles between the extraordinary, the revelation of the gods' secrets, and the magnificent world unfolding in its most splendid colors. Myths become reality, and mystery never truly disappears. The legend of the nun begins here!
