I Rely on the Underworld to Save the Common People

Have you ever thought that diseases that have existed since ancient times were born from diseases invaded by other worlds? Have you ever thought that the mysterious underworld in the cold forest supports the spirits of ancestors who can cure diseases and slay demons? Have you ever thought that in the world where spiritual energy is hidden, there are rebels who stick to the legacy of their ancestors? In the peaceful and peaceful human world, endless diseases have penetrated; In the inaccessible and dark place in the far north, the heroic spirits of our ancestors are guarded! Why can't the ancestral heroic spirits who defend the human race in the nether world be reincarnated? In this world of "people", the "disease" needs to be eradicated!
