I don't know how to summarize this article at the moment. In fact, the concept of this article was conceived almost two years ago, and the dense outline of the book was written more than a year ago. However, I probably took my relatives and friends too seriously, and the moment I was abandoned, I couldn't even code. However, I still want to give it a try, not for others, just for myself, and keep writing, even if it is only this article...
Of course I will be happy if someone supports me, but if no one reads it, I will try my best to keep writing.
