In the World of Demons and Ghosts, I Rely on the System to Become a God of War

This is a world of ghosts and monsters. Human beings can be food for the monsters and monsters, and they have been fighting against them for a long time. The human race developed ghost masters. Ghost masters are divided into innate ghost masters and acquired ghost masters. Innate ghost masters can awaken to their souls and practice ghost ways at the age of eight. Acquired ghost masters have failed to awaken and lack spiritual strength. They can refine demons and ghosts to allow themselves to practice the ghost way. Since refining is difficult to match the natural awakening, practice is relatively dangerous. If you cannot control it or are seriously injured, you will suffer backlash. Ordinary mortals can improve their blood and internal energy and strength through martial arts training. In this way, cultivation is slower, and it often takes decades or decades to achieve certain achievements. The realm is divided into: 1. Third-rate master, 2. Second-rate master, 3. First-rate master, 4. Innate extraordinary, 5. Grandmaster, 6. Marquis, 7. King, 8. Emperor, 9. Great emperor, 10. God of war.
