Heavenly Master Has a Ghost on His Body

After death, the soul returns to Hades. A soul with deep resentment has the ability to hide from heaven and remain in the human world, turning into a fierce ghost. There are also souls with deep feelings of love. After arriving in the underworld, in addition to reincarnation, they can also sign a ghost contract with the underworld, undergo nine tests, and can also settle in the ghost world or wander around the world of the world. The heavenly masters in the underworld specialize in punishing ghosts, but they cannot find the ghosts who signed the ghost contract unless they interfere with the living beings in the underworld.
