After witnessing your parents dying before your eyes, you actually mastered the power of Nine Yins and Nine Yangs. Then a conspiracy to kill you began to attack and defend the aliens. A bloody killing swept through the entire martial arts world. The world regarded you as a catastrophe in this martial arts world. However, not only did you not take it seriously, you even founded the Demon Sect with the slogan "Men should practice peerless martial arts and kill all enemies in the world." Since then, you have been divided into two martial arts circles with the "famous and decent sects", fighting to the death!
