The problem I see isn't the "bad English", but your understanding with the raw text itself and martial arts terms in general. I don't have the terms understood either.
For someone with a good heart, that's an awful lot of advertising on the chapter and ads on your site.
If you would like to improve, I'd recommend starting from chapter 1, with your fast translations, you'd reach the later chapters in no time.
I see more effort in putting links to your site and commenting everywhere rather than taking time to work on the translation terms. I feel offended from the lack of respect to the original author of this series, you have literally said you went for a fast translation rather than the quality of the translation, if you are working to improve, take time to properly translate rather than post 3 chapters a day.
