Ansh Scans is that online fan translation group for a whole bunch of Korean webnovels, right? I see their work pop up on aggregator sites all the time. I’ve never seen them officially compile and release anything as a downloadable ebook file you could load onto a Kindle. Their thing seems to be putting chapters up on various reading websites, usually with ads everywhere. Those sites let you read online, maybe save a chapter for offline viewing within their app, but that’s not the same as a proper EPUB or PDF file you own.
If you really want an ebook version of something they translate, you’d probably have to find a community that manually scrapes the text and formats it themselves, which is a hassle and the quality is hit-or-miss. Honestly, the reading experience on those ad-infested sites is so bad I usually just wait for an official translation to hit a platform like Webnovel or Yonder, even if I have to pay. At least then it’s clean and supports the author.
