Quick Answer
Worth reading if you're a Murim regular curious how one of the genre's most recognizable clans got started, though the story is still finding its footing and the art is functional rather than flashy this early on.
Quick Verdict
“Genuinely fresh angle on a Murim genre staple, built around watching Tang Mujin grow into the founder of a clan you may already recognize from a dozen other Murim series.”
Best for: Murim readers who enjoy origin stories and want to see the mundane, ground-level beginnings behind a legendary clan's later reputation.
Not for: Readers who want immediate high-stakes power fantasy rather than a slower, doctor-turned-craftsman-turned-martial-artist build-up.

Tang Mujin is a young physician at his family's clinic in Sichuan when a strange dream shows him becoming Ou Yezi, a legendary blacksmith who forged divine blades and ascended to immortality. Dangmunjeon, also circulating under the English title Tang Clan Legend, uses that dream as the spark for a genre rarity: an origin story for one of Murim fiction's most recognizable names. Readers of Murim manhwa have run into the Sichuan Tang Clan and its poison-and-hidden-weapons specialty dozens of times as an established faction; this series is about how it got that reputation in the first place, following Tang Mujin's evolution from doctor to blacksmith to martial artist.
The original web novel by Je J. Herbin ran on Naver Series from 2023 to 2024, and Song Ui-seop's webtoon adaptation began on Naver Webtoon in August 2025. There's no confirmed official English release yet, so English-reading access currently depends on fan translations.
The founding-story angle is the whole appeal, and it works because the series takes its world-building seriously instead of just retconning a legendary clan into existence. Watching Tang Mujin's skills stack, medicine, then blacksmithing, then martial arts into the toolkit that will eventually define the clan gives his power growth a grounded, earned quality that's rarer in a genre that often just hands its leads a cheat power on page one. The story also does real work explaining details other Murim series take for granted, like why the Tang Clan leans on poison and hidden weapons rather than straightforward swordsmanship, which gives genre veterans a satisfying sense of connecting dots.
The supporting cast helps too. Reader reviews single out a female co-lead introduced partway through the run who gets genuine credit as the mind behind the clan's signature contraptions, rather than being sidelined as a love interest with no function.
The art is functional rather than a selling point on its own, it renders characters and settings clearly but doesn't have the polish of the genre's more visually ambitious entries. Because the series is still relatively early in its run, some factions and side plots (a beggar sect's internal conflict, the absence of an established orthodox alliance) are introduced without much context yet, which can leave newer readers a little unmoored. And without a confirmed official English license, anyone who wants to read it now is relying on fan translations rather than a stable, licensed source.
An origin story that finds a genuinely fresh angle on a familiar Murim institution, worth a look for genre fans curious how the Tang Clan's reputation actually started. It's more of a slow build than an immediate power fantasy, and the art and some underdeveloped side plots keep it from standing out on craft alone, but the premise itself is doing real work that most Murim manhwa never bother with.
Strengths
Weaknesses
The Sichuan Tang Clan's Entomologist
A different, unrelated series that also uses the Tang Clan, following an outsider who joins the clan rather than founds it.
The Genius Swordsman of Mount Hua
A more traditional sword-focused Murim story if the founding-a-clan angle isn't the draw for you.
No. Both use the Tang Clan setting, but Dangmunjeon (also known as Tang Clan Legend) is an origin story about the clan's founding, while The Sichuan Tang Clan's Entomologist follows an unrelated modern-day reincarnator who joins the already-established clan.
No, it's an ongoing manhwa. The webtoon adaptation began in August 2025 on Naver Webtoon, based on a completed web novel.
There's no confirmed official English release yet; it's currently only readable through fan translations.
