I'm guessing you're asking about the novel 'Supreme of Ten Thousand Swords'. The plot is about an itinerant cultivator from the Primordial Realm, Chu Li, who reincarnates as a young man. He then embarks on a path of martial arts cultivation that defies the natural order. He regards the sword as the most important and the myriad worlds are under his control. I recommend this novel to you. I hope you like it!😘
