The Ordinary Me Became the Strongest in the Human World?

In a world full of harmony, there are seven realms: The Realm of Power of Physical Skills and Mass: Giant Realm The realm of wisdom in science and technology and industry: the dwarf world The dark realm of evil and cruelty: Demon Realm The Realm of Justice and Shining Light: Fairyland The Realm of Life of Agility and Longevity: The Spirit World The Abyss and the Realm of Chaos of Creation: The Realm of Space and the realm of incompetence without talent: the human world. World view: These six worlds form a sphere (the giant world, the dwarf world, the demon world, the fairy world, the spiritual world, and the empty world) The space at the borders of these worlds is the space inside the sphere formed by the six worlds, which is called the human world. Concept: Originally, these seven worlds were supposed to be living and developing in peace, happiness, and independence without any hatred. However, for unknown reasons, dungeons, towers, and some unknown creatures appeared, and they came to the seven worlds that were defenseless. But not everything was tragic. At the time of their arrival, the consciousness of all the world's highly intelligent creatures was transported to an unknown space. They chose their own abilities and launched resistance against races and unknown creatures in exchange for so-called peace. Under this inexplicable coincidence, an ordinary student embarked on his own adventure like everyone else. And accidentally became one of the strongest men in the human world.
