A long time ago, human beings all over the world died in various harsh environments.
Many souls who are still worried after death are corrupted by the resentment of the surviving people and become ghosts when they have no way to become Buddhas.
After these ghosts gain more resentment, they will have supreme magic power. They find that the resentment is the strongest when a person is approaching death! It can provide more nutrients for themselves, so those ghosts keep killing... And the people who become ghosts cannot become Buddhas because their deaths are unclear. In order not to lose their souls, they also rely on killing to maintain themselves...
The world has become a living hell...
However, by chance, a princess in trouble discovered that she could see things that others could not see, and those seemingly dirty things were instantly purified with the touch of her own hand...
More and more people are awakening their spiritual abilities, and they find that when they say certain words, their spiritual abilities will react strongly, and these reactions can actually make the ghosts seem to be hurt and in agony!
So, this group of people began to use such spells to attack ghosts. Finally, the ghost was defeated.
However, the ghost gained a new power - human desire while lingering.
Finally, the war between humans and ghosts began again...
