I recommend "Virtual Sky Fantasy". This is a fantasy novel from before 2005. It is already completed and has been published in physical form. The vitality of the Celestial and Demon Realms was greatly damaged. The Celestial and Demon who lost their physical bodies in the war had no choice but to exist in the form of primordial spirits. They found suitable mortals to possess and become the "Protector Beasts" of these people. The mortals who possessed the "Protector Beasts" became "Imperial Censors". A graceful and beautiful young man who knew nothing about martial arts, no spiritual power, and only knew music had somehow become the trainer of the ancient demon god Chi You. How could he control this legendary and unpredictable ferocious demon god? How could he stay out of the storm that was about to rise in the human world? I hope you like this fairy's recommendation.
