A Journey of Salvation That Begins with Pirates

This is a fantasy world full of fantasy, with cities floating on the sea, fire-breathing dragons, and the towering mage academy. These are no longer adventure stories only found in books, but reality within reach. This is also a cruel fantasy world. The story of the ogre and the human-sized mouse is not a fairy tale told to children before bedtime, but a reality that lives in the mountains next door or even 30 meters below your home. In addition to these monsters, there are also disputes between intelligent creatures. Being hit by a fireball is no different from being hit by a cannonball. It will only leave a scorch on the ground. How can a half-vampire Norseman reach the top of the world and become the brave man who saves the world?
