"The Seductress Bell and Feather"
That child was just an ice and water phoenix, but this phoenix was a ghostly Yin Phoenix who finally worked for the Underworld!
The feather of a Yin Phoenix was extremely cold, and it was the thing that many souls liked the most.
Thus, people from the Underworld with a high position often used the Yin Phoenix's feather to hook the soul of their target.
Of course, the feather used was not a 'fresh' one that was still attached to the Phoenix.
Others only stole some feathers that the Phoenix shed during summer and other special cases.
This feather, coupled with the soul bell, made a top-notch soul-hooking tool known to the entire Underworld.
After all, the soul bell was also sold separately and many citizens of the Underworld got one or two for fun.
The effect of this tool could be imagined.
The moment Bello swung the cat teaser stick, the soul masters who were controlling their soul weapons suddenly froze on the spot.
