Driving a small sail while cruising in the boundless sea, due to the sudden bad weather, I was involved in this strange haze. When I woke up, I found myself on a beach on the coast. I didn't know where it was. I decided to survive first and slowly explore these endless coasts, which revealed mystery and weirdness. I wonder if I would encounter any adventure among these mountains? Or it's a huge danger... Or maybe I can meet someone like me.
