Fantasy: I Kill Ghosts and Subjugate Demons in a Different World

There are people, demons, and ghosts in this world, but there are no immortals or Buddhas. So how do humans gain a foothold in this world where demons and ghosts are rampant? The answer is martial arts and magic. The martial arts and magic in this world are very strong. After reaching a certain level of practice, martial arts can collapse mountains with one punch, or even break rivers with one palm; martial arts can overturn rivers and seas, and control extraordinary abilities. Because of a heavenly book that records many martial arts and techniques, the world is in turmoil again... When the court learns about the heavenly book, will it sit back and watch the world turmoil, or will it take a hand? This novel and its characters are purely fictitious.
