Master of Arcana!

Mystery is the nourishment that will prevent me from being ordinary.Having arrived in a world similar to the European modern era twenty years ago, Flynn, with his precocity, mastered a skill and finally became a respectable person.He originally thought he would marry, have children, and live out a quiet life, but he discovered that beneath the shadows of the world, there was another world.In that world, there are Arcane Masters who cultivate arcane arts, mastering extraordinary power.There are eerie creatures lurking in the darkness, watching humans, and feeding on humans.There are cultists of evil gods, worshiping evil gods, through bloody sacrifices to please the evil gods, exchanging power for them.There are evil gods wandering outside the world, peeking at the world, and just a touch of their power is enough to make people fall.Taking mystery as nourishment, after twenty years of ordinariness, he is no longer ordinary.
