One Sword Controls Nine Days

I have a sword that can suppress the nine evil spirits! I have a tower that can crush the gods and Buddhas of the ten realms! Three years ago, young Zhu Luoyu lost all his cultivation and became a useless person! Three years later, a mysterious black tower recast the young Zhu Luoyu, and Zhu Luoyu's martial arts journey began! However, is all this happening secretly or someone did it deliberately? As the fog is lifted layer by layer, bits and pieces of the truth emerge. How should Zhu Luo Yu choose? I am the respecter of the Eight Wastelands and Liuhe, and I am the emperor of the Nine Heavens and Ten Realms! All directions are silent, and all realms surrender!
