I Will Kill All the Evil in the World If I Bear the Injustice.

I died unjustly. I accidentally swallowed the demon's blood, killed the evil spirits, and awakened the yin and yang law enforcement system! On the night of returning to the soul, the ghost hunting conspiracy of the underworld is uncovered, the black-hearted hospital hides the organ secrets, and the souls of transnational war criminals are at large... Since the laws of heaven are unfair and the laws of the underworld are out of order, then I will ascend to the position of the underworld as a wandering soul! Kill the bad guys, clear up the shady story, extradite the heroic souls, and pay for the blood debt! From now on, the human world is a prison, and Yin and Yang are the boundaries. Anyone who harms me, deceives the world, or disrupts order will be killed by me with my own hands!
