Oh, hunting for 'Trap of the Ace'? That's a tricky one because its official availability is surprisingly limited. I spent ages looking for a proper digital copy a while back. From what I gathered, it doesn't seem to have an official global English translation published by a major platform like Webnovel or Dreame. That usually means the author might have originally serialized it on a Korean portal like KakaoPage or Naver Series, but accessing those often requires a Korean payment method and navigating the site in Korean, which is a huge barrier.
Your most likely legal route, if you read English, is checking if any fan translation groups have partnered with the original author for official distribution. Sometimes these groups move their work to sites like Wuxiaworld or similar aggregators that secure rights after a novel gains popularity. I'd start by searching for the novel's title plus 'official translation'—sometimes a fan project gets legitimized after the fact. If that fails, the only 100% legal way is the raw version on the Korean portal, which is tough but doable with a translation app extension, though it's a clunky reading experience. I ended up not reading it because the hassle outweighed my curiosity, which is a shame because the premise sounded fun.
It's one of those novels that exists in this frustrating gray zone for international readers—popular enough to have fan discussions, but not popular enough to warrant an official licensed release. I keep checking NovelUpdates every few months just in case its status changes, but no luck yet. Maybe if more people show interest on forums, a publisher might pick it up.
