Is There Anything Wrong with Being a Saint in Another World?

Dragons, elves, and magic all tell that this is a different world full of fantasy, so here comes the beautiful Elf Sister, Miss Orc! But my system seems to be contaminated, and the tasks issued are a bit strange. "Today's task is to help people solve their food problems. Reward: five loaves and two fish." "Today's mission is to destroy the sinful city of Sotoma. Reward: The Love of the Lord." Why are the grooved pigeons chasing me? All in all, this is a story about becoming a saint in a fantasy world.
