Synopsis

A gifted young man named Chen Ji finds himself stuck in a mental hospital, which is already a rough starting point. After settling a score with the person who killed his parents, he somehow gets thrown back in time to an ancient dynasty — and lands a gig as a medical clinic apprentice. Sounds peaceful, right? It doesn't stay that way. He gets pulled into the world of the imperial Secret Service, only to find out he's apparently also a spy for an enemy nation. So now he's juggling a dual identity in a political landscape where one wrong move gets you killed. This ONA from Cloud Art is based on a web novel, and the setup has that layered espionage tension where you're never quite sure who's playing who. The action-fantasy combo works because the stakes aren't just about fighting — they're about survival in a system rigged against you from both sides. Chen Ji isn't just punching his way through problems; he's navigating court intrigue, secret agencies, and his own murky loyalties. If you liked the political chess matches in Kingdom or the isekai-meets-espionage vibe of something like The Apothecary Diaries (but darker and more action-heavy), this could land well for you. Fans of Raven of the Inner Palace who wanted more combat might also want to keep an eye on this one. It's set for 2026, so there's time to get the source material on your radar first.
