I recommend " The Legend of Nine Dragons Sealing the Demon " to you. It's a fantasy immortal cultivation novel written by Mo Weitu. The novel described a disciple of the Divine Sword Sect who was born in an ordinary family and had a powerful demonic aura. He was also the one who had the secret behind him. The story revolved around the Nine Serenities Soul Devouring Sword. It was said that if one could get this sword, they could get the power of the Nine Serenities Hell Devil. I hope you like my recommendation.π
