[The Legend of Lu Xiaofeng] Tempered Edge

Simple blurb: A sword god and a sword immortal team up to run dungeons and go on adventures. Ten years to hone a sword, a hundred years to temper its edge. “You study the sword?” “I am the sword.” “I started learning the sword at seven, and mastered it in seven years.” “Thirty years to cultivate an immaculate sword heart.” “What joy is there in life? What fear is there in death?” “With an honest heart, I ask the sword, and at last I find my original purpose.” The strongest duo in the martial arts world, running all kinds of dungeons across different worlds.
