"It has a bit of a philosophical flavor to it..."
Haruno Sakura massaged her forehead, recording in her heart everything she had seen that day. Returning to reality, she picked up the "Yo-Yo" transformed from the Yin-Yang Treasure Bead, only to find that it had changed into a small, black stick with white rings at both ends.
Simple, unadorned.
It was about seven centimeters long, looking like a hairpin.
"What is this?"
"You also need a weapon. I noticed when you fought with Senju Hashirama you borrowed power and refined it into a staff, so I helped you reforge the Yin-Yang Treasure Bead in advance, turning it into an As-You-Will Cudgel that can coexist in yin and yang," Sun Wukong explained briefly, "It can grow large or shrink small, extend or contract, become thick or thin."
"But it's just a rudimentary form now. As a weapon for battle, it's indestructible, but it can't be considered a treasured relic. You'll need to constantly refine it with your spirit to make it perfect."
