If it's the refinement of the Soul Beads, then there is nothing unusual.
But if Su Ziyu directly refines ghosts, the Demon Gourd's pollution value will increase. He suspects that this is how Jiutun Tongzi turned it into a contaminated entity. This Great Demon somehow got his hands on this Demon Gourd, and it's said that after occupying Danbo Mountain, Jiutun Tongzi used human blood to brew wine, probably allowing the Demon Gourd to directly refine it.
"Can it even refine humans?" Su Ziyu was a bit curious, but dared not try it easily.
If he turns the Demon Gourd into a contaminated entity again, he would suffer a huge loss.
"Let's see if there are any ghosts around." Su Ziyu got up and looked at the sky. Since he couldn't sleep anyway, he might as well take a stroll in the Underworld.
There weren't many ghosts wandering in the Underworld nowadays.
