I wrote some old articles from three years ago and then discarded them. I don't know how much better I wrote three years ago than what I write now. Others are becoming more and more stupid, while I am becoming more and more novice. It's really not as good as it was back then, which makes me feel weak even when trying to fill my own pitfalls. Then I would like to thank my colleagues at 21 Martial Arts. If it weren't for your constant encouragement, I probably wouldn't have thought of writing this bloody article. The plot is based on the original work, and is probably just a combination of ambiguous words and all kinds of nonsense. The specifics are too long and I can't remember how it was set up in the first place, so I have to fill it in based on my feelings.
