Becoming the Swordmaster Rank Young Lord of the Sichuan Tang Family (Korean: 사천당가의 소드마스터급 소공자, RR: Sacheondangga-ui Sodeumaseuteogeup Sogongja) is a standout "fusion" Murim manhwa written by Gat-Jin and illustrated by 99. It has gained significant traction for its unique premise: transplanting a peak Western fantasy Swordmaster into the heart of the most famous Eastern poison-and-needle clan.

The story follows Adel, the strongest Swordmaster of a Western fantasy realm. After falling in battle, he is reincarnated as Tang So-hyeop, the youngest and most ridiculed son of the Sichuan Tang Family. In a clan that prides itself on poison, hidden weapons, and assassination, So-hyeop is considered a "failure" for his lack of talent in their traditional arts. However, by applying the principles of Western Sword Aura and mana-breathing to the Eastern Qi system, he begins to exhibit a level of power that the Murim world has never seen.
