Dlsite has updated its reader, and this manga is now only accessible via web browser. Consequently, my previous download method is no longer functional. The current download method results in slightly lower image quality compared to before. Until I find a new solution, the image quality is unlikely to match the previous standard. Please be advised.
My English is not strong, so this notice was translated using DEEPL. I hope it accurately conveys my meaning.

Dlsite更新了阅读器，该漫画现在只能网页阅读，所以我用的旧有下载办法已经失效，目前的下载方法图片质量较之前有一些下降，在我找到新方法前恐怕图片质量都无法与之前的相比，望周知。
