I Use My Mortal Body to Refine a Vicious Sword

On the night of the wedding, my bride, Chu Qingyi, the daughter of the leader of the martial arts alliance, pointed her sword at my Dantian: "Lin Qiwu, are you a good-for-nothing like you worthy of marrying me?" She doesn't know that I still have a blood letter written by the devil's saint in my arms: "Tonight, at midnight, I will come and snatch you away." Little did I know that the reason why I started practicing martial arts three years ago was to refine the most vicious sword in the world. When the watch drum was beating, the moment she cut off my meridians—— The roof shattered suddenly, and a man in red clothes fell like blood, laughing crazily: "Sister Qingyi, I want this person."
