Lynch, an ordinary (actually a bit unlucky) young man from Earth, inexplicably traveled to a fantasy continent where magic and technology coexisted, and races were harmonious (actually chaotic). He also brought with him a strange legacy: the ability to summon the legendary Sky City. His companions include the arrogant mage Afia, the cute orc Doru, the cold-faced assassin Sylvia, and a glib crab. In the process of wandering, escaping, and accidental collisions, everyone was involved in a power conspiracy between the heaven and the devil, and were forced to become a "drama adventure group" to save the world. Laughter and tears, crises and turning points were intertwined. In the end, everyone faced themselves, cracked the mysterious curse seal, activated the Sky City, brought peace and new life to the other world, and also achieved the "protagonist-level awakening" in their own lives.
