[At the beginning of the volume, this paragraph is before the table of contents] I hope to be able to define what I am going to say next. All of these things happened almost in the past few years, forcing me from an ordinary person to what I am now.I have tried many definitions of my experience, but to no avail.Not because the things I experienced were too noble, but because they were too complicated and obscure. But I still have to define it. I think all this is a nightmare that I don't want to wake up to. In the months leading up to writing these lines, I nearly woke up.But now, I find that I still want to go on with this dream.
