The origin of this article is just because when the author was reading most of the mecha and post-modern articles, the author expressed confusion about the existence of space buttons. It is not that he cannot understand it, but it is just because the development of dimensional space can be said to be a permanent issue of modern mankind, and more puzzles are waiting to be studied.
The author is just a chuunibyou with a little bit of obsessive-compulsive disorder. He really likes the setting of this kind of future world. After reading the article for many years, he still can't let go of the skipped period that should have a heavy color. That's why he opened this pit. When will it be completed? Is it possible to complete it... This question is not something the author will think about! ! !
PS The author is a complete idiot, and a lot of academic theoretical support was provided by Du Niang. Corrections are welcome!
