The idea of constructing this underwater world came from an animation I watched when I was a child, called Future Boy Conan, which tells the story of the protagonist and his grandfather living on an island after more than half of the earth’s land was destroyed in a war. In the early stages of the story, the underwater ruins are impressive, this scenario may be as anti-war propaganda, perhaps can make people recall childhood memories, or can be as simple as an experience of visiting ruins in the underwater world, after all, visiting underwater ruins is almost impossible in the real world.<br>
