Becoming the Swordmaster Rank Young Lord of the Sichuan Tang Family

Briefly about Becoming the Swordmaster Rank Young Lord of the Sichuan Tang Family manga:

The Sichuan Tang Family was formerly a prominent lineage of poison and secret weapons, but it has since declined. Tang Yeon-myeong, born there, gets infatuated with swords, recalling a previous life in which he reached the peak of swordsmanship. “In this life, I want to live quietly.” To live quietly, I must conceal my swordsmanship skills. However, there are too many barriers in my way.
